混合动力汽车参数远程监控系统的开发

以混合动力电动汽车为研究对象,进行了车辆运行参数远程采集监控系统的开发。利用下位机通过串口采集模拟CAN格式数据并通过GPRS无线通信模块将数据发送至远端服务器,最后由上位机数据处理软件对原始数据进行数据处理。针对系统的要求和特点,主要对下位机硬件进行了模块选型和整体设计并对上下位机软件进行了设计编写。最后以多台电脑作为模拟车辆数据发射源进行了实验,实现了数据的无线传输,同时对多个数据源进行数据接收,以及对数据的分析处理、回放,并可自行设置数据协议的功能。尤其是数据无线传输和协议设置功能,提高了诊断系统的便利性和通用性。

Development of the remote data supervisory system of the hybrid electric vehicle

Taking the hybrid electric vehicle as the investigation subject, this paper studies the remote data acquisition, supervisory control and redisplay system of the hybrid electric vehicle fault diagnosis. The system gathers the simulate CAN BUS data through serial ports by the data acquisition device and send data to the remote web servers by the GPRS wireless communication module. For the demands and features, the paper makes the module selection and design the hardware of lower computer ,and the software on the host computer and lower computer. It takes several notebooks as the simulate vehicle date emission source to make an experiment, achieving the function of wireless data transfer, data acquisition, supervisory, redisplay for multi hybrid electric vehicles at the same time, and protocol setting up. Especially the function of wireless data transfer and protocol setting up, make a big progress on the common use and convenience of fault diagnosis system.
