摘　　要：针对车辆段客车供电系统操作管理方式落后和电能浪费严重的问题,采用面向对象方法开发了一种低成本的电量远程监控系统。依据Modbus-RTU协议设计的异步串行通信程序,实现了对地面电源现场供电参数的实时显示及对多台分布较远的地面供电柜进行实时在线监控。对运行中的故障采用传输错误检测与控制、通信错误和传输超时处理的方法,保证了系统网络通信连接的可靠性和智能仪表实时数据传输的准确性。This paper developed an inexpensive power remote supervisory control system with object- oriented method to solve the problem of slow operation management of power supply of the passenger train and much power waste. Asynchronous serial communication procedure designed in terms of Modbus-RTU protocol realized real-time display of field power supply parameters of on-ground power and real-time online supervisory control of more on-ground power supply cabinets distributed apart. By adapting such methods of checking and controlling transmission errors, processing communication error and timeout to operational diagnosis, we ensured the reliability of network communication connection and accuracy of real-time data transmission.
