1.故障特点目前总线技术已广泛应用于工程机械中,其通讯方式大都以CAN数据总线为通讯基础,建立由多组电子控制单元组成的计算机网络控制系统。电子控制单元之间通过CAN数据总线实现数据传输,通过控制程序保证执行机构可靠有效的动作,实现工程机械安全、可靠、高效的运行。工程机械上的CAN数据总线控制技术较为成熟,其控制软件不易出现故障,其故障一般都是由CAN数据总线、外接传感器、控制开关、相关连接线路等硬件问题引起。
1. Fault Features At present, bus technology has been widely used in construction machinery, and most of its communication to CAN data bus as the basis for the communication, the establishment of a multi-group electronic control unit composed of computer network control system. Electronic control unit through the CAN data bus to achieve data transmission, through the control program to ensure that the implementing agencies reliable and effective action, to achieve safe, reliable and efficient operation of construction machinery. CAN data bus construction machinery control technology is more mature, the control software is not prone to failure, the failure is generally caused by the CAN data bus, external sensors, control switches, related connection lines and other hardware problems.
