| Abstract: | A system design and realization of the front - end apperceiving of internet of things based on UHF RFID, and the function of its main modules are introduced. The hardware ,working flow and design of software are elaborated. The system＇s working frequency is adjustable between 860 -960MHz, supporting the standards of EPC Gen2 and ISO/IEC 18000 -6B/6C. RF chip AS3992 is used as main part ,with the internal PA which integrated on the RF chip, and some peripheral circuits, the RF front - end of the system. The advantages of this system are small size,light weight, high integration and low cost. The realization result shows that the system＇s communication distance can get 2.5 m, meeting the practical application need. |
