基于ZigBee技术的RFID读卡器的设计

mobile RFID reader based on Zigbee wireless technology is designed in this paper.This paper shows the block diagram of the mobile reader,and detail the external circuit of the RF chip CC2420, an card reader integrated chip MF RC522,and main control chip MSP430F1611,as well as the reader's software architecture.The reader collect tag data, and send the data to the server automatically through the ZigBee network. Mobile RFID reader reduces the RFID system network cabling, saves the cost, and is used more convenientiy and flexibleiy.Because of the virtue of fast network deployment and simple maintenance,the system is used in temporary emergency situation.
