摘　　要：针对WINDOWS系统中的普通定时器定时精度低,不能准确测量数字式随动系统调转时间的特点,利用串口事件进行定时触发的测量机制,结合Windows高精度时间函数,设计出一种测量数字式随动系统大角度调转时间的机制,解决了用传统定时器所产生的记时不准和误差较大的问题,提高了随动系统指标的测试精度。Aiming at that the common timer timing precision in WINDOWS system is low and cannot be accurately measured with the characteristics of digital dynamic system switch time, using measure mecha- nism to have timing trigger of serial events and combined with high precision time function of Windows, we designed a mechanism for measuring the digital servo system of large angle maneuver time, and solved the problem of big error and incorrect timing generated by traditional timer, which improves the test precision of pneumatic system index.
