The Design of Equipment's ECU Fault Testing Device Based on Modular Technology
A large number of embedded controllers,sensors and intelligent components are used in engineering equipment,and the cou-pling degree of electronic system,hydraulic system and mechanical system is greatly improved,which leads to the difficulty of fault detec-tion,diagnosis and maintenance support.It is difficult for equipment maintenance personnel to master the working principle,fault charac-teristics and occurrence mechanism of the electro-hydraulic system,and it is difficult to judge and repair the fault in time and accurately af-ter the equipment fails.This paper explores the application of embedded technology and bus technology to design and develop the fault de-tection device of the electronic control system of engineering equipment.Kvaser dual-channel CAN analyzer is selected to collect the CAN bus signal of the equipment,and LabVIEW language is used to develop fault detection software to identify and diagnose the fault state of the electronic control unit of the equipment.Fault alarm,storage,trend analysis and prediction.The research results have important practical significance and significant military and economic value for improving the technical level of equipment maintenance support personnel.
