摘　　要：针对现有轮胎管理系统无法提供轮胎替换操作所需的安装位置和行驶里程等信息的不足,基于CAN总线和射频识别(RFID)构建了车胎信息采集系统。该系统设计了CAN解析模块用来解析车辆行驶里程信息;采用RFID技术完成对车胎电子标签的信息读写;通过以太网实现RFID读写器与控制端的信息传输。实验结果表明:该系统能准确采集车辆速度并在行驶状态下(速度<50 km/h)对电子标签进行有效读写,实现了对轮胎安装位置的存储及电子标签信息的实时显示功能,极大地方便了车辆检修人员快速、准确地进行车胎替换与管理工作。Aiming at the problem that the existing tire management system is unable to provide information such as installation location and driving distance required for tire replacement operation,the information acquisition system was designed for vehicle tire based on CAN bus and RFID.In this system,CAN analysis module was designed to analyze the vehicle mileage information.RFID technology was used to complete the information reading and writing to the tire electronic label.The information transmission of RFID reader and control terminal was realized through Ethernet.The experimental results show that the system can acquire the vehicle speed accurately and read and write the electronic tag effectively in driving state(speed<50 km/h),and implements the storage of tire installation location and the real-time display of electronic tag information,which provides great convenience for vehicle maintainer to conduct tire replacement and management work quickly and accurately.
