Abstract

An interrogator system design scheme is proposed based on UHF radio frequency identification（UHF RFID）

which is a popular technology in the front-end apperceiving system of internet of things.Working principle of the UHF RFID system is given

and the hardware and software of the system is elaborated respectively.The system test results is analyzed.The main controller peripheral circuit

the design of UHF interrogating module circuit

and the software flow of the system are described.The results show that the design

which support the protocol of EPC GEN2 and ISO/IEC 18 000—6A /6B can be realized.The system has the advantages of simple structure

small size

low power consumption

and the working distance can reach 6m

which can meet the needs of practical application.
