A Design of Performance Testing Platform for Electronic Control System on Excavator

针对传统测试方法中效率低、耗资大等问题,提出一种电控系统性能测试平台的设计方案.设计代替挖掘机各电气部件与传感器的工作状态信号模拟电路,并使用LabVIEW软件开发监控界面.测试平台通过串行口和CAN总线建立与电控系统之间的实时通信.实验结果表明:该测试平台能实现对电控系统电气逻辑功能、主控制器算法有效性等项目的测试.

A design of performance testing platform for electronic control system is presented to solve the costly and inef- ficient problem of traditional testing methods. The signal analog circuit used to replace various working status of electron- ic components and sensor in excavator is designed. In addition, monitoring interface is developed with LabVIEW soft- ware. The real-time communication between the testing platform and electronic control system is established through seri- al port and CAN bus. Experimental results show that, the testing platform can realize the tests of the electrical logic function of electronic control system, the effectiveness of main controller algorithm and other projects.
