　　Principle of industrial RFID identification system

　　A complete RFID system consists of reader, RFID tag and computer system.

　　Reader is a key part of RFID system, which is mainly composed of wireless transceiver module, antenna, control module and interface circuit. These readers can write and read the information in RFID tags, and they are an important part of the data acquisition terminal in RFID system. The reader communicates with the RFID tag through the wireless transceiver module, the control module is responsible for processing instructions and data, and the interface circuit is used to connect the reader and the computer system.

　　RFID tag is a data carrier used to mark the object to be traced, which records data information and can read and write with RFID reader. Tag antenna and tag chip are the core components of RFID tag. The tag antenna is used to receive the signal sent by the reader and transmit it to the tag chip, which is used to store and process data information.

　　Application advantages of industrial RFID identification system

　　In the industrial production environment, data recognition technology plays a vital role. At present, barcode, QR code and RFID technology are commonly used data identification technologies in industrial scenes. However, each technology has its specific limitations. For example, although bar code technology is widely used, it needs to match a specific light source when reading data, and it has high requirements on the brightness of the light source. In addition, it needs to be scanned by the scanner aiming at the light in the visible range in order to read the information successfully. This technology requires high mechanical accuracy. Once the objects bearing bar codes such as trays are deformed, the bar codes may not be recognized. In addition, barcode recognition can only be scanned one by one, and only one barcode can be read at a time, which greatly reduces the work efficiency. Moreover, because the bar code is easy to wear and dirty, its service life is short, and it cannot be reused after being modified.

　　On the other hand, although the two-dimensional bar code provides a solution in terms of information capacity and adds the function of information error correction, it can realize the functions of reading and anti-counterfeiting on the surface of articles through laser engraving technology, but there are still some disadvantages. For example, its application scenarios are relatively limited, which can not fully meet the needs of complex application scenarios in industrial production.

　　To sum up, although barcode, QR code and RFID technology have played an important role in industrial data identification, they all have certain limitations. Therefore, it has become an urgent problem to find a more efficient, reliable and adaptable new data identification technology in the industrial field.
