Research Of RFID System Based On ZigBee Technology

Radio Frequency Identification system is an untouchable auto-identifying technology, which identifies an object and gains the relevant data through the radio signal. But the present RFID technology has a low flexibility when reading and writing systems,a short transport distance,a low safety characteristic and a high equipment cost. In order to solve the problems of RFID, developing a RFID system based on the latest RFID system and ZigBee technology.The paper introduces development situation of RFID technollgy at home and abroad and researches the background of the ZigBee technology and ZigBee protocol in detail. ZigBee technology has a low power-waste characteristic, a low equipment cost, a high reliability and a great network capability. According to the function and the working principle of the RFID system based on ZigBee technology, the whole project of this system has been designed. The paper gives the hardware circuit design of the system, selects STC89C52RC and MF RC500 as the microprocessor and the radio frequency chip of radio frequency module ,and chooses MSP430FG4618 and CC2420 as the microprocessor and the radio frequency chip of ZigBee wireless communication node. According to the function of the system, the software structure has been designed, including the RFID reader and the communication between the ZigBee nodes based on ZigBee stack. Finally the debugging process of the system has come true. The system features with flexibility, no extra orientation configuration, long working distance, and extensibility.In one word, the hardware and software of the RFID system based on ZigBee technology have been designed。It has resolved the abuse of existing RFID system, increased the area of application, and discussed the future of the technology.
