Design and Implementation of Portable Reader System Based on UHF RFID

Firstly, this paper briefly introduces UHF RFID technology, and then analyzes the domestic and foreign background of UHF RFID technology, the research progress, the existing problems and the development trend. Secondly, aiming at practical application, we design a set of small and low power consumption UHF RFID portable reader system. Hardware design is the design of the lower computer, including STM32F103ZET6, the RFID module of AS3992, the power supply, the display of ILI3941, the wireless module of ESP8266, the memory card and the key module. The software design includes the server system program design, the mobile application (APP) system program design, the lower computer system program design and the improvement of collision prevention algorithm. Finally, the test and analysis are carried out.
