摘要
针对汽车用转向柱锁性能检测过程中多任务并行执行的要求,系统采用了多线程技术,在驱动待测产品运动到各数据采集点以实现精确定位的同时,对所采集的各项数据进行实时处理并实时地显示运行结果。介绍了系统的硬件构成和软件设计流程,并详细阐述了多线程技术的实现。现场运行结果证明该系统使用方便,性能可靠,能满足检测系统对实时性、可靠性和运行效率的要求,实现了汽车用转向柱锁动态特性的自动精确测量,并取得较好的经济效益。
Aiming at the request of synchronization existing in the test system of dynamic characteristics of steering column lock,the problem of synchronization between motion control,data acquisition and results display was successfully solved by using the multithread technology.The hardware structure and the software design were introduced,and the multithread technology was described in detail.The results show that： the system can meet the need of real-time,reliability and efficiency of guidance.The precise parameter testing technology in course of the system is greatly improved and remarkable economy benefit is gained.
