摘　　要：针对联合疏通车电控系统的智能化水平和可靠性水平不高的问题,采用CAN总线技术,搭建以主控制器、I/O扩展模块、可编程显示器和遥控接收器为节点的CAN总线网络。各节点之间以CANopen协议进行通讯,通过识别数据的COB-ID号,使各节点相互传输数据,从而实现对动力系统、高压疏通、吸污/反排等模块的准确可靠控制,以及对整车关键参数、元件执行状态和故障诊断信息的有效监控。For the problem of sewer dredge vehicle electronic control system of intelligent and reliability level is not high, CAN bus technology is used in the sewer dredge vehicle, set to the main controllerthe I/O extension module, programmable display and remote control receiver for the node of CAN bus network. With CANopen protocol to communicate between each node and by identifying the COB -ID number of the data make each node to transmit data to each other. So as to control the main functional modules, including power module, sewer dredging and sludge suction/discharge module accurately and monitor the critical parameters of the vehicle, the status of each actuators, diagnosis information efficiently.
