Mobile computer is also known as handheld terminal PDA, can help us complete work, study, entertainment, etc. on the move. Classified by use, it can be divided into industrial-grade handheld terminals and consumer-grade handheld terminals. Industrial-grade handheld terminals are mainly used in the industrial field. The common ones are barcode scanners, RFID readers, POS machines, etc., which can be called handheld terminals;
The industrial-grade handheld terminal has data storage and computing capabilities, has display and input functions, can perform data communication with other devices, has an independent battery power supply, and can be used for secondary development. It is characterized by firmness and durability, and can be used in many places with relatively harsh environments. At the same time, it has made a lot of optimizations for industrial use characteristics.
Industrial-grade handheld terminals are specially designed and developed for industrial fields or special work application scenarios. In terms of function, the industrial-grade handheld terminal has a built-in scanning head, which can scan one-dimensional, two-dimensional barcodes, and even DPM codes. Equipped with Bluetooth, camera, call, GPS, multi-mode wireless network, data communication and other functions, with large capacity battery, long battery life, and high industrial grade above IP65.
The industrial-grade handheld terminal equipped with RFID reading function can automatically identify the target object and obtain relevant data through the radio frequency identification signal without manual intervention. It can identify high-speed moving objects and identify multiple RFID tags at the same time. For low frequency, high frequency, UHF, active, etc. All of the above are not available in consumer-grade handheld terminals.
Handheld terminal refers to Android or WinCE operating system, memory, CPU, graphics card, screen and keyboard, with data transmission and processing capabilities, has its own battery, mobile data acquisition and processing terminal, widely used in logistics, retail, medical, manufacturing, Transportation, energy, finance, government and public, and other industries, and play different roles.
Handheld terminals can be attributed to changing cumbersome and lengthy data records into devices that can be scanned, automatically matched, and confirmed, which greatly improves the efficiency of item processing. Automatic matching by scanning the code to minimize the error rate. Turn the operator's work of repeatedly checking data and acceptance into an easy and simple barcode scanning. Real-time data collection, transmission, and upload greatly simplify business flow compared with traditional models.
The most important of these is to configure a unique barcode or electronic label for the product. The electronic label or barcode corresponds to the product's production date, product name, price, manufacturer, batch number and other information. In the stages of product warehousing, transportation, etc., the handheld terminal can be used to read and update product information. During product transportation, the location of the product can be uploaded to the system background at any time through the real-time positioning function of the handheld terminal. In the sale or use stage of the product, you can use the handheld terminal to read all the information of the product, and if there is a problem, you can trace the responsibility.
Main features include:
- Barcode scanning: There are currently two technologies for barcode scanning, laser and CCD. Laser scanning can only read one-dimensional barcodes. CCD technology can recognize one-dimensional and two-dimensional barcodes. The more popular view is that when reading one-dimensional barcodes, Laser scanning technology is faster and more convenient than CCD technology. Handheld terminals with barcode scanning capabilities are often called barcode data collectors.
- IC card reading and writing: handheld terminals with integrated IC card reading and writing functions are usually called IC card handheld data terminals, and are mainly used for IC card card management
- Non-contact IC card reading and writing: handheld terminals integrated with non-contact IC card reading and writing functions are usually called non-contact IC card handheld data terminals, and are mainly used for non-contact IC card management.
- Built-in information button: The so-called information button is a built-in non-contact IC card chip, which is mainly used for patrolling.
- Fingerprint collection and comparison: the handheld terminal with integrated fingerprint collection module is mainly used for public security, social insurance, etc.
- GPS: Industrial applications are mainly used for public security, and more in the civilian market, providing electronic maps and positioning services for drivers
- GSM/GPRS/CDMA wireless data communication: the main function is to exchange real-time data with the database through wireless data communication. There are mainly two situations where this function needs to be used. One is the application that requires high real-time data, and the other is that it may be needed when the required data cannot be stored in the handheld terminal due to various reasons in the application. The data is too large, and it may also need to be kept secret, etc.
- Bluetooth communication: Bluetooth communication function is a new generation of short-distance wireless communication technology, which is mainly used in PDA and mobile phones at present. Other data terminals have gradually begun to use this technology. The short-distance Bluetooth communication can reach 10m, and the long-distance Bluetooth communication can reach 100m. When the amount of communication data is not large, Bluetooth technology can also replace 802.11B networking.
9. 802.11B: As the mainstream technology of wireless LAN, 802.11B is currently developing very fast. Many handheld terminals have been equipped with this function. Handheld terminals with this function can form a network within a relatively large range and communicate with PCs and servers. etc. for data exchange, wireless data exchange can be carried out in large closed spaces (such as factories and warehouses). If the space exceeds the range that the wireless signal can cover, you can add multiple nodes to solve the problem
Application fields:
