Abstract :
An UHF RFID(radio frequency identification) reader is implemented to meet the needs of data acquisition in the IOT(internet of things). Firstly, this paper introduced the principle of the reader. The RF front-end circuit was taken as the focal point,and it was simulated with ADS. AS3992 and its peripheral circuit implemented the transceiving of RF signals, STM32 completed the process and control of baseband signals, USB and RS232 communication interface were designed.And also we have considered the collision algorithm and low power details. Test results show that the reader supports ISO/IEC18000-6B/C, reading and writing distance up to 3 m, rated power less than 5 W. It is of miniaturization, long distance reading, low power consumption, easy to expand. It could meet the practical requirement of perception layer in intelligent IOT.
