摘　　要：针对多种类型的车用开关,设计了一款具有通用性的车用组合开关耐久性检测系统,应用CAD/CAM设计了可对旋动、拨动、抬动3种开关动作进行耐久检测的多工位试验台,软件系统采用双控结构,中控主机利用Windows API多线程技术编写通信程序,ARM分控机采用针对共享内存的多线程编程技术OpenMP完成了多工位控制的调度程序设计,实现了多开关并行检测,提高了系统的检测效率。A versatile durability testing system is designed for vehicle combination switches of different kinds. With application of CAD/CAM, the system consists of a multi-station bench which can test durability of 3 switch movements-turning, toggling and lifting. The software system has a dual-control structure-the central control host uses Windows API multi-threading technology to write communication programs;the ARM sub-controller uses multi-thread programming technology OpenMP for shared memory to design the multi-station control scheduling program – which allows the system to test multiple switches in parallel, improving the testing efficiency.
