基于CAN总线和2.4G无线网络的RFID收费系统

摘要

Traditional RFID charging system which uses RS-485 has the disadvantage of lower real-time and communication efficiency. So a new RFID charging system based on CAN bus and 2.4G wireless network is come up with. One CAN node can control the data transmission of six RFID terminals through the 2.4G wireless network. The system is tested by transmitting data from the temperature sensor through wireless network and the result proves the correctness of this design.%针对传统基于RS-485总线的射频识别技术(RFID)收费系统具有实时性差和通讯效率低的缺点,提出了一种基于CAN总线和2.4G无线网络的新型RFID收费系统.该系统采用2.4G无线网络环境,使一个CAN节点能够控制六个RFID收费终端的数据传输.应用温度模块获取的数据的无线传输对该系统进行测试,测试结果表明该方案设计的正确性.
