摘　　要：针对不同总线协议的车型需要反复去现场更新车载终端中的程序问题,设计一种灵活可配置总线的新能源车辆远程监控系统。首先车载终端采用数据透传的方式读取CAN总线信息,通过CDMA 1X EVDO无线通信网络进行数据通信;然后数据通信服务系统根据应用服务系统界面的配置结果,自动生成带有编号的协议解析脚本,根据CAN总线数据包中的协议版本号进行脚本解析,对数据进行解码,并存储到数据库服务系统中;最后通过Web界面访问应用服务系统,对协议版本及内容进行选择,实现对车辆信息的准确监控,大大提高了生产研发效率。测试结果表明,该系统能改善可扩展性及软件可移植性,为未来新能源车辆的全面推广和资源整合打好基础。The vehicles with different types of bus protocols have to repeatedly go to the site to update the procedure in the vehicle.mounted terminal,so a new energy vehicle remote monitoring system with flexible configurable bus is designed.The method of data pass.through is adopted in vehicle.mounted terminal to read the CAN bus information,and the data communication is executed through the CDMA1X EVDO wireless communication network.The data communication service system automatically generates the numbered protocol parsing script according to the interface configuration results of the application service system,and the script is parsed on the basis of protocol version number in the CAN bus data packet.The data is decoded,and stored in the database service system.The application service system is accessed by means of Web interface to choose the protocol version and content,and realize the accurate monitoring of the vehicle information,which can greatly improve the production and development efficiency.The test results show that the system can improve the scalability and software portability,and lays a foundation for the comprehensive promotion and resource integration of new energy vehicles in the future.
