Reception of goods tsd. TSD (data collection terminals) - how to use, what you need, use and connection

It is difficult to imagine modern logistics and trade processes without various automated devices and systems, whether it is a WMS system for warehouse management or various automated racks. A variety of equipment and device manufacturers provides the end user with a wide choice and the ability to choose equipment for their specific needs. One such device is a data collection terminal (TSD). There are many different types of TSD from different manufacturers equipment. Below we will consider what TSD is, their types and their purpose.

What is a data collection terminal (TSD)

TSD is a specialized portable computer designed to collect data, process it and interact with the information system in the organization. This is a type of equipment for

The simplest modification is a device the size of a cell phone, with a built-in barcode scanner. The most complex models can work underwater or at temperatures down to -50 °C. With the help of TSD, warehouse workers process goods, ship out-of-pocket orders, or take inventory.

The principle of operation of the TSD

The principle of operation of the TSD is the reading of information by scanning a barcode and further transferring this information to the information system.

Also, tasks can be issued to warehouse workers on the TSD screen, and if additional functions are available, the TSD can be used as a printer or intercom.

Transfer of information to the information system is possible via wireless communication or by connecting the TSD to a computer via a cable.
Some TSDs can be attached to the hand, and some are equipped with a pistol grip for easier operation.
There are also industrial data collection terminals that scan specialized types of codes or operate under difficult environmental conditions.

How to use the data collection terminal

Using the TSD is quite simple, you need to point the laser scanner at the barcode so that the terminal reads the encrypted information. Further, this information is stored on the internal storage for subsequent transfer to the information system or is transmitted immediately via a wireless connection. A special program for TSD is usually installed on the terminal itself, which processes the scanned information.

Also, tasks can be issued to warehouse workers on the terminal screen, and if there are additional functions, the TSD can be used as a thermal printer or an intercom.

Using the terminal, you can take inventory, receive and ship goods, check the expiration date of goods, check the correctness of price tags on the trading floor. When barcoding documents, terminals can be used in document management.

How the data collection terminal works

Data transfer to the information system:

After reading the information from the barcode, the data must then be transferred to the information system of the organization. For this, data collection terminals are equipped with various data transfer interfaces.

Some terminals are connected to the information system in real time and data exchange takes place via wireless communication,
and some scan information on internal storage and further transmit it when connected through a wire.
It is also possible to transfer information via memory cards.

The main methods of data transmission TSD:

Connecting the TSD via a wired connection. Connection interfaces: RS232, USB. Sometimes a so-called cradle stand is used (a stand for a TSD connected to a PC). There are several options for the operation of the cradle stand - one-to-one (one base stand + one data collection terminal) and multi-point (one stand + several scanners). The advantage of a wired connection can be considered a long battery life, because. there is no need to waste energy on maintaining the communication channel. The disadvantage is the lack of constant communication with the information system and feedback.
Connecting the TSD via a wireless connection. Connection interfaces: BlueTooth, Wi-Fi, IrDA (IR port), GSM. There are restrictions on the working distance of the terminals: with a BlueTooth connection they work at a distance of up to 15 meters, Wi-Fi - up to 100 meters. IrDA is an infrared port, it works at a close distance of up to 10 cm. To connect via GSM, the information system must have a modem to receive the signal, it works in the zone of a stable cellular signal. Advantages in constant connection and feedback with the information system, always up-to-date information on TSD. The disadvantages include a slightly higher price than wired terminals.

Scanner operation:

Modern barcode scanners have differences in the type of reader, decodable codes, the ability to read QR codes and RFID tags.

The reading element device can be laser or LED.

Laser TSDs are the most common and use a red diode laser. Scans a standard linear (1D) barcode of various sizes (up to several decimeters).
An LED scanner (image scanner) takes a picture of a barcode, and then analyzes and extracts information.
The imager can scan more complex barcodes (1D, 2D, mixed, damaged, QR codes) and work at a distance of up to 15 meters.
Scanner RFID - tags are not very common yet, but they successfully combine several technologies (bar coding and radio frequency identification). They can be used for labeling expensive products.

There are also specialized scanners for recognizing codes made using Direct Marking Technology (DPM). The application of a barcode is possible by drilling, laser engraving, etching with chemical reagents, extrusion (perma-code) and other methods, depending on the type of surface. Such coding is often used in industrial production. The work of a simple scanner is hampered by the fact that the barcode is made on the very surface of the product, whether it be metal or polyethylene. Therefore, a special DPM scanner was developed.

Operating system

The data collection terminal is a specialized mini computer with its own processor, operational and long-term memory, and any computer must be controlled by an operating system. There are several such operating systems for TSD:

The old operating system is found mainly on older models and has a number of limitations. On a DOS system, only certain software developed by the device manufacturer generally runs. It is also possible to use software developed in programming languages such as C++ or Visual Basic.

DOS terminals have a monochrome display, low computing power and internal memory storage. It would seem that such terminals are not in demand and are already out of use, but with all the shortcomings, such TSD have a number of advantages over more complex terminals. Low power consumption and, as a result, longer operation time from a single charge, system reliability, affordable price, which still allows us to compete in the equipment market.

Windows

This is the most common and flexible operating system for the data collection terminal. Windows Mobile is a more universal system, it can be used in various modern terminals, but this operating system has higher system requirements. It is considered the most popular operating system, because. a lot of applications have been developed for it for all areas of trade and logistics. Windows CE is lightweight and flexible to use.

Android OS

A fairly new operating system that has recently appeared on the market for data collection terminals. It is distinguished by ease of use, lower cost of developing applications for the terminal (compared to applications for Win), and the absence of complex software licensing. Interested in small and medium businesses.

Relationship with WMS (thin client, thick client)

To work on the data collection terminal, one device is not enough, you also need the appropriate software. This software (TSD driver) is developed for the operating system installed on the terminal. Large developers of their own corporate information systems develop their own programs for TSD. Some hardware vendors offer comprehensive solutions for TSD + drivers for popular ICs (for example, for 1s). In general, there are two approaches to the organization of the workplace.

Thin client based

For Windows devices, Remote Desktop Protocol or the Citrix Metaframe client can be used. With their help, you can remotely display the contents of the server desktop. Also, to create a "thin" client, you can develop WEB applications. In this case, any web browser supported by the system will act as a “thin” client on the TSD. For DOS terminals, you can use telnet. In this case, the application running on the telnet server will be displayed on the TSD screen using the telnet client. The wireless connection mode ensures uninterrupted communication between the TSD and the information system. This approach is considered obsolete, because. equipment running DOS systems is becoming less and less.

Organization of a workplace based on a "thick" client

A "thick" client is an application developed specifically for a specific data collection terminal. The application can be developed for both offline and online modes. Modern operating systems in TSD (Windows, Android) allow you to develop various applications for the terminal. The disadvantages of a “thick client” are the binding to the operating system for which the application was developed. There is a risk of data loss if, for some reason, the data is not transferred to the information system.

Interface (sensor, buttons)

Different terminals use different ways to enter information. It can be a keyboard with a different number of keys or a touch screen, it is also possible to combine a touch screen with function buttons. The number of buttons varies, both in the types of TSD and in the models. The advantages of the touch screen include the fact that any number of buttons and their combination can be displayed on the screen. The disadvantages are that it is not always convenient to press buttons on a small screen, the accuracy of entering information may suffer. Keyboards in terminals are also different. In the simplest version, these will be keys with numbers only. Some models have keys with numbers, each of which has its own set of letters for typing, and there are keyboards with a full set of letters and numbers, necessary for the full input of information. The number of buttons in such terminals is different (12, 32, 53, etc.). A terminal with function keys, up to 8 pieces, is considered convenient. There are terminals with a full qwerty keyboard, but these are already specialized industrial models.

Additional features of TSD

There are models of terminals, with their own characteristics.
An optional barcode printer can be connected to some RTD models, allowing you to print and replace labels if they are found to be in error.
It is also possible to have a camera for additional shooting of objects and entering information into the database.
Some TSDs in the form of PDAs have a GSM module and can be used as a cell phone.
Sometimes TSDs are equipped with backup batteries of small capacity and size. In the event of a discharge of the main battery, the backup allows you to save data and, if possible, transfer them to the IC.
There are models with an adjustable laser angle for scanning barcodes, which can reduce the muscle load on workers, and this affects labor productivity.

Battery, autonomy

One of the main characteristics of TSD is the battery life. Naturally, the larger it is, the better. At a minimum, the TSD should last for one 8-hour work shift, and some models, with a large battery capacity, work up to 24 hours without recharging. Most models of data collection terminals are powered by Li-ion or Li-pol batteries. The rest are from ordinary alkaline batteries or other types of batteries. Some TSD models come with removable batteries that can be hot-swapped. The advantage of this is to ensure continuity of operation, but as a result, the price of such models is higher.

Temperature, protection

There are specialized scanners that can operate in a wide temperature range, from -50 °C to + 50 °C. They have enhanced protection against the external environment, a durable housing, sealed connectors, and a screen with shock-resistant glass. Also, TSDs are equipped with enhanced sound and light indication, for operation in conditions increased noise and limited visibility. Scanners have a rubberized housing and can withstand repeated drops from a height of up to 2 meters. Such scanners have a protection class, which is determined by the international standard IEC 60529, denoted by IPXY (X - the degree of protection against the ingress of foreign objects, dust. Y - the degree of protection against moisture).

Types of TSD at a glance

Data collection terminals can be divided into several generally recognized categories. There are also many different companies that produce TSD. There are also separate services that repair TSD.

TSD elementary grade , equipped with a simple barcode scanner and a small number of function keys. Designed for small organizations. The data obtained as a result of barcode reading is stored on the device and later transferred to the information system via a wired connection. The setup of such TSDs is minimal.

Advantages: low price, ease of use, reliability.

Disadvantages: lack of computing power for complex warehouse operations, little functionality, the need to connect to a computer for data transfer.

Many firms produce entry-level TSD

TSD with handle- a special kind of terminals, which are distinguished by an attached pistol grip for ease of use. Handled RTDs often have a long-range barcode reader that works up to 9 meters away and can scan through glass, allowing forklift workers to read codes without standing up.

Advantages: ease of use, protection from the external environment, all the functionality of full-size TSD.

Cons: price.

TSD with handle

Wearable TSDs are attached to the wrist, leaving your hands free, and the ring-shaped laser scanner is put on your finger. Maybe voice control. A very handy device when workers need to have their hands free while scanning.

Advantages: ease of use, protection from the external environment, all the functionality of full-size TSD.

Disadvantages: price.

It is a compact device for reading a barcode and storing the received data. In the company's online store Company"THIS" you will find various models terminals, as well as a range of accessories to facilitate their use.

Features of data collection terminals

TSD can significantly simplify warehouse (receipt and movement of goods, inventory) and trading operations, as well as minimize the likelihood of errors. Using terminals allows you to:

exclude the occurrence of regrading;
reduce inventory time;
simplify the search for goods in the warehouse.

For ease of use, the terminals are equipped with a keyboard, a screen and a rugged housing. The main difference between a TSD and a barcode scanner is its great functionality, the device allows not only to read and store information, but also to transmit it over the air or by direct connection to a computer, and print receipts. Modern models have modules for reading information from smart cards and RFID tags.

The principle of operation of the TSD

The TSD works like this:

Reading information from the bar code located on the label, packaging of each product.
Processing of the received data and their ordering according to a certain structure (this structure is set by the user, based on the characteristics of the enterprise or personal preferences).
Saving the received data and transferring information about all products to the main computer of the enterprise (using USB, infrared, Bluetooth, Wi-Fi).

For example, you have delivered a batch of goods and you need to enter information into the company's database. You simply read the barcode (indicating the quantity of goods), connect the TSD to the computer in any convenient way and transfer the data to 1C.

Types of TSD

Accumulative type terminals can collect and store information for its further transfer to the database. This is the best and cheapest alternative to wireless barcode scanners.

Radio terminals can operate in three modes:

Batch mode used only to transfer information from terminal to terminal. The device works autonomously, the operator does not need to use a data exchange cradle. After activation this mode the radio interface turns on and sends a request to the server about the availability of jobs. At the end of the work, the mode is turned off to save battery power.
Online mode implies a permanent connection with the server. This mode is the most convenient, because it allows you to keep the information up to date and quickly fix errors.
Remote Desktop Mode displays the screen of the remote computer, on which all the main work is carried out. Models that support Windows and have a good screen resolution can work in this mode.

Also, TSDs differ in the amount of memory and the conditions in which they can work. Industrial models perfectly cope with their functions in adverse environmental conditions - dusty rooms, at low temperatures, high humidity.

How the terminal differs from the scanner, how to choose a TSD, which models of devices have earned a reputation for being inexpensive and reliable, is described in the article.

Owners of even small stores with a team of 3-5 people prefer to automate the accounting of goods by purchasing equipment that can read barcodes. One of the leading devices of the automation system is the data collection terminal (TSD). He is responsible for reading, memorizing, processing information "hardwired" into the barcodes of the goods. How the terminal differs from the scanner, how to choose a TSD, which models of devices have earned a reputation for being inexpensive and reliable, is described in the article.

How is a TSD different from a scanner?

A portable data collection terminal is a miniature computer running on the Microsoft Windows Mobile, Palm OS, DOS or Linux operating system. It is equipped with a scanner that reads product codes, as well as a module that communicates with the warehouse computer via WiFi.

Build a customer base with a ready-made loyalty system, use a flexible discount system to attract customers during off-peak hours. Operate like a big store, but without the cost of specialists and server hardware today, start earning more tomorrow.

Stationary devices are also produced, but these devices costing from 2-3 thousand dollars are designed for use by large warehouse and logistics companies that process several hundred items of cargo every day.

The TSD color display is often made using the “touch-screen” technology, only you need to work on it not with your fingers (as with a smartphone), but with a special stylus included in the kit.

An ordinary scanner will read the code (they are at the cash desks of stores), and the terminal will not only read it, but remember it and make it possible to immediately add the quantity, batch number and make notes on the condition of the goods. The data entered into the device is stored in its memory, then transferred to a computer with an installed accounting program via a wired or wireless connection.

Three steps towards choosing a terminal

A person who has never encountered the choice of special equipment will simply be confused in the abundance of brands, models, modifications of data collection terminals. Start with the simplest:

Step 1: Decide what the machine is for

The cheapest model (200-300 USD) with a minimum of functions can accept the goods, conduct an inventory, move between the warehouse and the trading floor. But if the business develops, the possibilities of technology should not interfere with this development.

Example: a device that does not support wireless connection with a PC is selected, the store has moved, the warehouse area has increased by 2 times, the number of goods received daily has increased. The memory of the device was not enough to free up space, you have to constantly run to the warehouse, connect via a cord to a PC, spend 2-3 hours per shift on this.

Step 2: Consult with a specialist

The data collection terminal should not complicate life, but simplify accounting. Therefore, it is important that the filling of the device is synchronized with the accounting program installed in the store. The IT specialist who installed the software will be able to suggest which models are suitable. If automation of accounting is just planned, immediately discuss the set of equipment that will be needed in your store.

Step 3: Determine the budget

The cost of models with approximately the same capabilities differs significantly. It's better to decide which one price category devices affordable for the store. There will be 2-4 device models in the chosen price niche, of which you can find the most suitable ones: technical specifications, availability of support service, service center, warranty period, replacement speed of a broken (defective) device.

When the first steps are taken, start studying the technical characteristics.

Technical specifications

How much the terminal will help in the operation of the store, how much it will cost, is determined by the technical characteristics:

1. Read type. There are three types of devices available:

laser: read linear barcodes, work poorly with damaged, blurry labels, cost from $150;
equipped with a photo scanner(largest group): reads 2D codes, PDF417 and QR codes, can be used to work with EGAIS, will read even a damaged code, the cost starts from $ 350-400;
working with RFID tags or RFID: works only with special tags (such products are marked with natural fur, expensive clothes), optimal choice for large stores with a warehouse area of 200 sq. m.

2. Hull protection: each model is supplied with data on the recommended operating temperatures, moisture resistance, protection from mechanical stress. There are models that operate at a negative temperature, after being completely immersed in water, transferring a fall from a height of 2-3 meters. For heated warehouses, most of the protective functions can be neglected, but if you have to take the goods on the street, it is better to choose a device that can work normally in adverse environmental conditions.

Comprehensive trade automation at a minimum cost

We take a regular computer, connect any fiscal registrar and install the Business Ru Kassa application. As a result, we get an economical analogue of a POS-terminal as in a large store with all its functions. We start goods with prices in cloud service Business.Ru and start working. For everything about everything - a maximum of 1 hour and 15-20 thousand rubles. for the fiscal registrar.

3. Method of transferring information to the host computer: wireless or using a cord (the second name is a batch) connecting the TSD to the PC. Typically, devices with wireless connection additionally equipped with a cord for RS-232, USB port. Wireless data transmission is possible via IrDA, Wi-Fi, Bluetooth, GSM. Batch-standard models are cheaper, but supplement them wireless module will not work.

The data collection terminal (TSD) is a device that is in demand and often indispensable in a modern trading enterprise. Let's get acquainted with the specifics of its purpose and with the features of choosing a TSD model suitable for specific tasks, taking into account a rather large number of technical characteristics of this type of equipment.

What is it and how to use TSD

A data collection terminal is the traditional name for a device that is used in the management of a trade or warehouse, and is a relatively small (designed for manual use) gadget adapted to:

to reading various barcodes (in which information about goods is encrypted);
to the transfer of read data to some external computing module (as a rule, to writing data to the built-in memory, in many cases, to processing this data using built-in computing modules).

Perhaps a long preliminary placement of the collected information inside the terminal, and then "batch" data transfer to an external module with a set frequency. But it is not excluded (and, moreover, it should be considered as one of the typical scenarios) such transmission in real time. Depending on the specific tasks of the trade or warehouse management process, a specific method (or their combination) of data processing is selected.

Thus, the main functionality of the device fully corresponds to its name: the terminal is designed to “collect” the required data in a certain way (in practice, to scan a barcode in which this data is encrypted). This function is inextricably linked with another - the function of ensuring further processing of "collected" data - in internal or external modules.

Video - how to use the data collection terminal TSD CipherLab 8001L:

In practice, the terminal - for example, in a warehouse, can be used to compare the actual quantity of goods received with their quantity according to the invoice (or other accounting documents). For this purpose, an invoice file is written to the terminal's memory in the prescribed manner (or a connection is provided with this file, which is located on an external medium), with which the data received from the device's scanner is then verified. As soon as all the goods actually accepted by the warehouse employee are scanned on the TSD, and information about them is compared with the file, the warehouse program will determine the degree of correspondence between the data on the file and on the scanner. If there are discrepancies, the TSD user will be notified about this (and this notification will list the missing items - or, conversely, the extra ones for which there is no data in the invoice).

Thus, the data collection terminal is generally a control tool. There is a certain normative number of objects taken into account, and there is an actual number - based on the results of operations with these objects. With the help of TSD, data on both parameters are compared. Then, on the basis of the information received, the employees of the enterprise take the necessary actions (aimed at eliminating discrepancies or others that are provided for by the instructions or orders of colleagues).

The main areas of use for data collection terminals are as follows:

Carrying out operations related to:

with the movement of goods in the warehouse, between the warehouse and the trading floor;
with an inventory of goods;
with control of conformity of the prices for the goods.

Accounting for documentation, control over the correctness of the data reflected in them.

The functionality of the data collection terminal may involve various “feedback” options, which involve displaying information on the screen of the device in response to one or another reading operation. For example - a detailed display of data about the scanned product (its characteristics, quantity, location) - which can be used by an employee of a store or warehouse for various purposes.

Other useful features that many modern data collection terminals are endowed with include their suitability for use as a cell phone or walkie-talkie, as a device for accessing the Internet - if software capabilities allow, as a network messenger in an enterprise. In general, the functions of many modern TSDs are close to those that characterize modern mobile gadgets - in essence, terminals become their variety (which, at the same time, is used to solve highly specialized tasks).

Due to the presence of a built-in scanner, the data collection terminal can be used in those areas of the organization of the store, where scanners are used as such - for example:

at the checkout - in order to speed up data entry into the cash computer when generating a receipt;
on the trading floor - in order to obtain information about the price and other information about the product at the request of the buyer.

Due to the fact that the data collection terminal, as a rule, is built into a single information base of the enterprise, it does not require additional complex configuration at the program level. The device quickly integrates into the current infrastructure at the checkout or on the trading floor.

In some cases, TSD can also find application outside the trade sphere. For example, when accounting for correspondence and parcels at the post office, cargo and cars at various transport infrastructure facilities.

How is the data "collected" on the TSD processed?

The TSD can be connected to an external computing module - which processes the "collected" data - in various ways - wired and wireless. Increasingly, data collection terminals with Wi-Fi and those that are adapted to transmit data via mobile Internet are in demand. But at localized workplaces - for example, at the acceptance of goods to a warehouse, it is quite a working option - wired connection terminal to the warehouse computer. There are terminals optimized for placement on cars, special equipment.

The information read on the TSD can be processed on the external module for different purposes and with the help of different software. It is common to use popular 1C warehouse accounting modules and their competitors - that is, those solutions that are being implemented in order to automate the management of trade and warehouse. And the TSD themselves thus become part of the toolkit for such automation.

What are the benefits of using it

So, regardless of the specific method of using the terminal, its main purpose is to automate one or another part of the production process. In the absence of a data collection terminal, a store or warehouse employee would have to perform the same accounting procedures - but only manually.

Thus, TSD is, first of all, a tool for saving time and labor of personnel. According to a number of experts, appropriate automation speeds up key warehouse and inventory operations on average up to 5 times - in comparison with the time it takes to perform such operations manually. In addition, the need for a large number of employees in those areas where such operations are carried out is reduced.

Data collection terminals, unlike a person, work flawlessly (provided, of course, that they are correctly configured both in software and in hardware). Errors will be minimized when comparing different types of data, compiling registers, checking various indicators that people work with in sales and warehouse management areas.

The use of data collection terminals allows you to organize more effective control over the work of employees in the relevant areas. The controlling person - the head of the warehouse or his immediate supervisor, can implement programs at the enterprise that allow tracking each operation performed using the TSD. This will avoid uncontrolled movements of goods - each of which will be taken into account in this program. The level of personal responsibility of warehouse workers is increasing: the probability of product leakage to the side, its replacement with poor quality, and failure (with subsequent inaction in its elimination) will be minimized.

Design and technical characteristics of TSD

Data collection terminal - as a rule, a small device, the size of an average smartphone, is designed primarily for portable use (but there are also stationary models of TSD). Many modern TSD models are adapted to operate in difficult temperature conditions, have a durable housing that is resistant to external mechanical stress.

The terminal can be controlled using the built-in keyboard or touch screen - more and more are equipped with it modern models TSD. Perhaps, of course, a combination of different device management tools.

From the point of view of hardware capabilities, the data collection terminal is a very productive computing solution. In some cases, its characteristics are comparable to computer ones or those that are typical for modern mobile gadgets. A typical combination of the following hardware components for a mid-priced TSD is:

processor with a frequency of 1-1.5 GHz;
RAM with a volume of about 256 MB;
internal memory up to 32 GB (expandable with plug-in memory cards).

A typical display, which is equipped with terminals, has a vertical orientation, a diagonal of about 3-4 inches and a resolution of about 480 by 800 pixels.

Video - connecting the data collection terminal to 1C:

TSD can be equipped with various types of scanners. Most often it is:

laser and LED scanners (installed mainly on budget models of terminals);
photo scanners or image scanners (installed on more expensive devices).

Laser scanners are usually cheap, however, they have a disadvantage - in the form of limited adaptability to reading erased bar codes. Photo scanners are generally very good at recognizing even low-quality, dim barcodes.

LED scanners are a solution that can be considered a kind of "compromise" between laser and image scanners. On the one hand, an LED scanner is about the same price as a laser scanner. On the other hand, it has a number of technical advantages over it, especially in terms of:

barcode scanning on deformed (jammed, scratched) paper;
barcode scanning on glossy surfaces;
reading color barcodes (for example, red).

Laser and LED scanners are approximately equal in their capabilities when reading data from barcodes:

well readable, printed on undamaged surfaces;
small size (with narrow stripes).

In turn, laser scanners certainly outperform LED scanners in scanning bar codes at considerable distances - more than 30 cm. Image devices are also adapted to reading codes at a similar distance.

Note that the rule "laser - cheap TSD, image - expensive TSD" has exceptions. There are high-tech laser scanners adapted for installation on premium models of data collection terminals. Their ability to read low-quality barcodes can be quite high.

There is a special subspecies of scanners for TSD - RFID devices. They are designed to read data at a great distance from the scanning module (sometimes up to tens of meters). This data is generated using special radio tags. As a rule, RFID scanners are in demand at large cargo terminals, ports, and industrial enterprises.

Video - how to use the TSD data collection terminal in 1C Trade Management:

A typical data collection terminal is characterized by the presence of a built-in battery that can provide autonomous operation for 8-16 hours (with a recharge time from zero of about 8 hours).

In the software part, modern TSDs operate, as a rule, under the control of special modifications of the Android and Windows OS, sometimes DOS. Less often - factory firmware. Thus, it is possible to install special applications on the terminal (or implement software algorithms based on existing applications), which adapt it to solve various types of production problems.

How much does a data collection terminal cost, depending on the type of TSD

The classification of data collection terminals into the following main varieties is common:

storage devices.

Their main feature is their adaptability to the accumulation of a large amount of data on operations that characterize the work of the production site where the terminal is used. In many cases, these data can be edited in the prescribed manner, supplemented by others, used as an object for analytics.

broadcasting devices.

Their main purpose is the rapid transfer of data to external computing modules - where, as in the case of devices of the first type, they can be accumulated and used in various ways.

However, on modern market data collection terminals, there are more and more solutions that essentially combine the functions characteristic of the two indicated traditional varieties of TSD. Thus, the above classification of terminals should be considered very conditional - like, for example, their traditional division:

according to the degree of adaptability to movement (as an option, based on the capabilities of the battery) - to mobile and stationary;
according to the method of data exchange with external devices- wired and wireless.

The fact is that many of the modern terminal models, firstly, are extremely difficult to classify according to the above criteria (since they are, in fact, universal), and secondly, assigning a specific TSD model to one or another type may not give anything. in terms of determining the degree of its compliance with the tasks that are typical for the production site where it is planned to use the terminals.

It can be quite useful to classify modern TSD according to the following main criteria:

Operating system level .

Here are the terminals:

single-tasking (with DOS, with factory firmware);
multitasking (running Android and Windows).

Indeed, data collection terminals with a single-tasking OS are designed to solve only the task that the warehouse worker faces directly at the moment of using the terminal. It cannot use any of the device's parallel functions. In turn, these functions can be applied to multitasking TSD. For example, along with scanning a product, a warehouse worker can view the current balance of such a product on the screen.

Despite being single-tasking, terminals of this type are in demand, because, in turn, they have many advantages over multi-tasking ones, for example:

stability in work (on a single-tasking OS, the likelihood of freezes, crashes, virus infection is minimized);
speed of operation (to perform a computational operation in a single-tasking OS, it is required to be able to perform tasks at the expense of a much smaller processor and memory resource - as a result, the device can be equipped with the most low-cost microcircuits, which reduces the overall cost of the terminal).

Thus, a single-tasking TSD is, in fact, a "pure TSD", performing all its key functions - but at the same time cheaper in comparison with multitasking devices.

The Casio DT-970 device (cost - about 25,000 rubles) can be attributed to the number of popular single-tasking terminals on DOS. For comparison, its functional analogues from among the budget multi-tasking TSDs can be bought, as a rule, for no less than 28-30 thousand rubles (Proton PMC-2160, PMC-2260 devices).

At the same time, multitasking terminals, for obvious reasons, have a higher adaptability for integration into the company's existing inventory infrastructure. At the level of a full-fledged OS - Android or Windows, it is almost always possible to implement the necessary applications for integrating TSD with the inventory infrastructure.

So, in the PMC-2260 device, a quick integration with EGAIS is implemented at the software level (while ensuring data transfer to it from single-tasking TSD in many cases requires the development of separate software interfaces - which in most cases is not economically profitable).

Supported barcodes .

According to this criterion, data collection terminals can be classified in the most general case:

on devices that support scanning 2D codes;
to devices that do not support such scanning.

A common variation of 2D code is the QR code. Regular codes - with "stripes", these are 1D codes.

The ability to read 2D codes requires higher technological effectiveness from the terminal, especially in terms of processor performance (since information “encrypted” in a two-dimensional code is usually incomparably more complex than that written in a one-dimensional code). Therefore, the difference in the price of TSD - supporting and not supporting complex codes scanning, can be noticeable.

For comparison - one of the cheapest single-tasking terminals with support for scanning 2D codes - the CipherLab 8200 device, costs about 56,000 rubles, that is, more than twice as expensive as the Casio DT-970 device. At the same time, cheaper devices can be found in a number of multitasking TSDs. For example, a Datalogic Memor X3 device on Windows OS costs about 43,000 rubles.

Adaptability to work in difficult conditions .

So, we can distinguish data collection terminals:

adapted to difficult climatic conditions - for example, at low temperatures;
having a shock-resistant case;
resistant to moisture.

Among the most "frost-resistant" devices are the solutions of the CipherLab line - devices 9730L (71,000 rubles), 9700L (75,000 rubles), CP60L (84,000 rubles). All of them are able to work at temperatures from minus 30 degrees.

The most protected from falls are Casio DT-X200-10E devices (66,000 rubles), DT-X200-11E (71,000 rubles), DT-X200-20E (85,000 rubles). All of them are able to withstand drops from a height of up to 3 meters.

The most waterproof devices have an IP67 index. There are quite a few of them, and the Casio DT-970 budget terminal known to us belongs to them. According to the criterion of moisture protection, therefore, there is no correlation with a high price - this is a universal TSD parameter.

Type of scanner used in TSD .

This is the most important, and at the same time very controversial criterion. We noted above that with the general rule - when a laser scanner, which is cheaper compared to a photo scanner, is inferior to the second one in terms of adaptability to recognize low-quality bar codes - there are exceptions in the form of technological laser devices working at recognition of such codes is very efficient.

So, for example, the Zebra MC3190-Z premium RFID terminal (its cost is 257,000 rubles), at the user's choice, can be equipped with both a 1D laser scanner and a 2D photo scanner (despite the fact that all configurations cost the same). Thus, under certain technological conditions, a "cheaper" recognition technology may be more needed than a more "more expensive" one. But here we are talking about a very narrow scope - after all, the specified scanner from Zebra is a typical industrial RFID solution, and the specifics of its use should be carefully transferred to other areas.

Regarding the “cheapness” of a laser (or LED) and the “high cost” of an image, not everything is clear either. Of course, the general price trend - in accordance with which laser or LED RTDs, all other things being equal (with exceptions - for example, the device from Zebra) are cheaper than those on which a photo scanner is installed - is still relevant. But, firstly, the difference is still not astronomical. For comparison - one of the cheapest TSD with a photo scanner, the Proton PMC-2260 device (32,000 rubles) - costs a little more than the cheapest Casio laser terminal. There are other inexpensive models with a photo scanner - for example, Honeywell EDA50k (34,000 rubles).

Secondly, it is impossible to assert a direct relationship between the type of scanner that is installed on the TSD and the device's ability to recognize a certain type of codes. Of course, image scanners are the most versatile. They read any type of codes. At the same time, there are many terminals with a two-dimensional laser scanner - for example, Zebra MC2180 (45,000 rubles), Datalogic Skorpio X3 (76,000 rubles).

Thus, if in the process of using the terminal it is supposed to read two-dimensional codes, a device with a laser reader, which supports the recognition of such codes, may well be used for this purpose. If desired, in most cases, you can find the closest analogue of such a TSD in terms of price - but only with an image scanner, since in practice the difference in the cost of devices, as a rule, is not large with other comparable characteristics.

Note that LED TSDs adapted to reading two-dimensional codes are a very rare occurrence. In this sense, this type of terminals are much inferior to laser and image terminals.

But if scanning 2D codes is not expected, then the LED terminal will be an excellent alternative to the laser TSD. As we noted above, LED devices can be more effective when reading codes on deformed paper, on glossy paper (but inferior to a laser when reading codes at a distance). Examples of budget devices with an LED scanner are the single-tasking CipherLab 8200C terminal (25,000 rubles), the multi-tasking CipherLab RS30-C / R (43,000 rubles).

In many TSD models, two modules are pre-installed at once - for example, one-dimensional laser and two-dimensional imager. Thus, the type of TSD scanner is a criterion in relation to which it is very difficult to single out universal patterns in terms of application practice. Every time you need to look at the specific conditions for using the data collection terminal, the characteristics of the scanner (or scanners) pre-installed in it, its suitability for installing the necessary scanning modules one by one.

And if you still try to identify some patterns in terms of the use of scanners, then it is very conditional to cite the theses that:

to scan barcodes that are regularly located at a large (more than 30 cm) distance from the scanning module of the TSD, laser and image scanners are best suited;
for reading barcodes, which, due to the specifics of the production process, may be partially damaged, become fuzzy - image scanners are best suited;
for scanning barcodes on glossy, deformed surfaces, image scanners will be optimal, and if the budget is limited, LED scanners.

LED terminals in most cases are not suitable for reading 2D barcodes.

It should be noted that in many TSD models - moreover, this rule characterizes both budgetary and more expensive solutions, it is provided for the installation of a scanning module of a specific type at the user's choice. You can purchase two modules at once (as a rule, this is a pair consisting of a laser and an image scanner) - and then, if necessary, use the first or second.

AvailabilityRFID-module .

The criterion under consideration has a low position only from the point of view of the likely narrowness of the scope of the device (which is due to the fact that a small percentage of enterprises have an objective need for an RFID terminal). However, in relation to the corresponding narrow area, the presence or absence of an RFID scanner in the TSD is undeniably the most important parameter that will come first.

Video - inventory of bags using an RFID data collection terminal:

In practice, RFID modules are used, as we noted above, at large cargo terminals and in industry. These are highly technological hardware components - and their installation in the TSD significantly increases their cost. But you can also find quite low-cost RFID solutions. For example, the Casio IT-G400 multitasking terminal based on Android (cost - 60,000 rubles).

Availability of additional communication accessories .

For example - a microphone, a built-in camera. These accessories can be used to communicate and exchange information between warehouse employees who work at a distance, and, moreover, due to the work they perform, they need to use such communication tools.

Examples of devices that have both a microphone and a camera are Casio DT-X30 terminals (46,000 rubles), Honeywell Dolphin 60s (53,000 rubles), Proton PMC-1100 (63,000 rubles).

How to choose a TSD for your needs

There are quite a lot of criteria for choosing the right data collection terminal (taking into account the variety of technical characteristics of the device discussed above). Which of them are considered the main ones can be determined according to the “industry” principle.

For example, a terminal used in a freight warehouse will most likely not be used in any other way than to enable its main functionality - which is to scan bar codes (almost always in such cases - two-dimensional) and transfer data to an external computer. module for further processing. Therefore, in the case under consideration, the cheapest single-task terminal with a one-dimensional laser reader will be optimal.

However, if the warehouse is open and located in a cold region - as an option, in one of the ports of the Northern Sea Route, where minus 30 is almost a resort temperature, then, most likely, TSD, at least in winter, will be used regularly in extreme climatic conditions. In this case, attention will have to be paid to the frost-resistant terminal.

In turn, in industrial production, in construction, there is an obvious need for TSD that is resistant to mechanical stress. When working with goods on an industrial scale, it is quite obvious that a high-tech RFID device will be needed.

If the terminal is supposed to be used on the trading floor, then, most likely, the case will be limited to using its most basic functions - reading data from bar codes (probably one-dimensional) and simultaneously transferring them to the inventory system. Again, the most budgetary, not necessarily frost-resistant and protected, single-tasking terminals with a simple laser scanner are able to cope with this task.

Among the leading brands-manufacturers of TSD include such companies as:

Casio;
datalogic;
honeywell;
Proton;
Zebra.

Excellent terminals are produced by the Russian brand ATOL. Among them - one of the most affordable multitasking 2D terminal ATOL Smart.Lite (costs 19,000 rubles), a MobileBase DS5 device with two scanners - laser and image (71,000 rubles), a secure terminal ATOL Smart.Droid 1D / 2D (29,000 rubles).

The argument for choosing a terminal from a Russian supplier may be the ease of upgrading the scanning module (if such an option is provided in a specific RTD model), repair, flashing - due to the availability of spare parts and, possibly, a wider geographic coverage of the territory of operation of service centers.

How to choose software for it

Choosing a data collection terminal as a hardware solution is half the battle. Its practical application, as we already know, involves the transfer of "collected" data for further processing to an external computing module - on which a special program is installed.

Such solutions on the Russian market are presented in an exceptionally wide range. An example of an inexpensive, versatile, and at the same time functional option is the ATOL Mobile Logistics program (LINK). It allows you to integrate data collection terminals and popular commodity accounting platforms based on 1C products.

This program involves the use of the terminal as an element of the inventory infrastructure, which operates on the basis of an algorithm that is developed using the configurator. This algorithm is created in the program in question and then loaded into the terminal. At the same time, the TSD must have the required hardware and software characteristics - for compatibility with the program (a list of compatible data collection terminals is given).

As part of the general scheme of practical application of the terminal, it is supposed to pre-load information on goods that are subject to accounting - in a warehouse or on a trading floor. Orders for shipment are formed at the warehouse - and with the help of the program, the corresponding orders are reflected in the TSD. The order includes an established list of information on shipped goods. Using a data collection terminal allows you to track the actual volume of shipped items - each of which is read by a barcode, the volume that is shown in this list.

Video - work with the data collection terminal:

The employee who uses the terminal promptly receives data on detected inconsistencies between the declared indicators and the actual ones, as well as instructions on the need to correct discrepancies. Also, using the data collection terminal, the employee can make notes in a special register about the identified damage to the goods, marriage, and indicate other important facts about the shipped items.

Upon completion of the shipment and upon the collection of all the necessary data on it using the TSD, all information is loaded into the accounting system. With the help of it, various accounting documents can subsequently be generated.

The procedure for using terminals on other types of software for TSD, in general, is very similar to that which characterizes the application of the solution from ATOL. Actually, this is due to the uniformity of tasks that characterize the use of TSD in the framework of typical accounting operations in a warehouse and in areas where goods are sold.

Thus, the main criteria for choosing software for data collection terminals will be - with the likely comparability of their basic functionality (which, one way or another, is aimed at integrating the TSD and the inventory interface - based on 1C or an alternative solution):

compatibility of software and a specific TSD model (you need to request lists of such compatibility from a specific supplier - as an option, referring to an example of such a list from ATOL);
compatibility of the algorithm for processing "collected" data, which is offered by the developers of software for TSD, with those production operations in which the terminal is involved.

And if such compatibility is not implemented by default in the selected (and suitable according to other criteria) software, then it is necessary to pre-determine the possible costs for the necessary modernization of the existing data “collection” or inventory infrastructure infrastructure - it is possible that they will turn out to be lower than the additional costs for installation of alternative software.

Summary

The terminal for data collection in terms of basic functionality is essentially a very simple device. Its main purpose is to collect information on objects in respect of which certain production operations are carried out (for example, acceptance or shipment) and to ensure the necessary processing of this information (for example, in order to compare the actual volume of goods received or shipped with the data reflected in attire and other accounting documents).

In the general case, the collection of such data is carried out by reading the barcode placed on the accounting object. Thus, the main criterion for the quality of the work of the TSD can be called adaptability to reading such codes:

accurately;
promptly.

For these purposes, it is necessary to introduce terminals in production, equipped with the required type of barcode scanners. In addition, the data collection terminal itself must be suitable for the conditions of use in a particular environment (at least taking into account climatic conditions).

The data collected by the terminal is subject to transfer to an external computing module. For this purpose, wired or wireless interfaces that are optimal for specific application conditions are used - which the device must be equipped with.

TSD can be used only for solving basic problems - and be single-tasking (both in essence and in terms of its technical capabilities). And it can be used as a multitasking device with an extended set of functions - for example, as a communication tool in the interaction of employees of an enterprise.

The choice of a data collection terminal with certain characteristics can be made taking into account the software factor with which the integration of the TSD is supposed. Compatibility is required between the algorithms for managing "collected" data, which are provided by such software, and software-hardware interfaces on a specific terminal model.
