基于无线传感器网络的RFID系统

采用无线传感网络ZigBee的树型组网方式代替传统的RFID网络系统,不仅能降低RFID系统的成本,而且能使RIFD组网更加灵活,省去了传统RFID系统繁琐的布线,提高了系统实用性和可靠性。系统由管理服务器、网关节点、路由节点、RFID终端节点组成。采用低成本通信芯片CC2430和FM1702SL组成RFID终端节点,具有体积小、低成本、低功耗等特点,适合使用在识别距离比较短,数据传输比较远,网络比较繁杂应用场合,系统具有较强的实用性和灵活性。

Design of RFID System Based on WSN

Instead of traditional RFID network system,the wireless network ZigBee sensing of the tree mesh way reduces the cost of RFID system,enables RIFD mesh more flexible,leaves out the traditional wiring of RFID and improves the practicability and reliability of the system.The system was made up of management network servers,gateway node,route node and RFID terminal node.The use of low cost communication chip CC2430 and the node FM1702SL RFID made RFID terminal node small,cheap and low consumption.It’s suitable for recognition in a short distance,comparatively remote data transmission,and mesh in school,parking,the security and other applications.The system has strong practicability and flexibility.
