混合动力汽车实时远程监控系统的开发

Research and development of the real-time remote monitoring control system of hybrid electric vehicles

采用GPS/GPRS的数据传输单元DTU(data transfer unit)和CAN总线数据采集模块,集成为车载远程数据采集终端,借助无线手机基站网络、Internet网络、并集成上层的数据监控软件,构建了混合动力汽车实时远程监控系统。车载终端采用内置CAN控制器模块的PIC18F4580和工业级DTU-MD610G,通过GPRS(general packet radio service)和Internet网络将数据及GPS信息传输到远程控制端,并以VC++为开发工具,编制了上位机的监控软件。软件系统不仅具有车载终端、服务器、客户端三者的数据交互和数据处理功能,并且具有CANoe数据回放及协议解析功能,增强了系统的通用性。通过实车实验表明,系统可以完成车辆状态和GPS位置信息的采集与显示。

This paper develops a vehicle-carried remote data acquisition terminal based on GPS/GPRS integrated DTU（data transfer unit） and CAN Bus data acquisition module,and built a parameter remote monitoring system of HEV with GPRS and Internet.By using PIC18F4580 with built-in CAN control module and industrial DTU-MD610G,we transmitted the parameter data and GPS information of the HEV（Hybrid-Electric Vehicle） terminals to the remote data control center through GPRS（General Packet Radio Service） and INTERNET.Taking VC＋＋ as the development tool,we programmed a monitoring software of data exchanging,data processing and monitoring.The software also has the function of CANoe data playbacking and strengthened the system versatility.Eventually,the parameter remote monitoring system of HEV is developed.The experiment results show that the system works well.
