摘　　要：构建了掌握电动汽车运行状态的远程监控系统。下位机有电池管理系统和电机控制器实现电池电机信息的采集,整车控制器通过控制器局域网络(CAN)实现车内数据通信,数据由CAN转为RS232。采用了通用无线分组业务技术,经数据传输单元传输,借助移动信号和Internet网络传至上位机。利用动态交换技术实现组态王和MATLAB及VB联合,然后利用MATLAB对接收的数据进行理论计算和VB调用MAPX控件,扩展了运算能力和定位功能。实际应用说明系统具有良好的实时性。A system was built to grasp the operating status of many electric vehicles. In the slave computer there were a battery management system and a motor controller to collect the informations from the battery and the motor. A vehicle management system relized the data communication with other units via a controller area network（CAN） and the data were transfered from CAN to the RS232. The data were transfered by a data transfer unit to the host computer by the general packet radio service（GPRS） technology and by help of the mobile signals and the Internet. The host computer used the dynamic data exchange technology to combine Kingview, MATLAB and Visual Basic（VB） by using MATLAB for theoretical calculation and VB calling MAPX control unit and the computing and positioning powers were expanded. The practical application of the system showed that the system was characterized by good real-timelyness, it will play an actual role in the development of the electric vehicle.
