摘要
介绍了DS-28型定时机构测试仪的研制原理,提出了利用光电耦合器将幅值变化的开关信号转换为TTL电平信号的方法,设计了支持硬件及软件结构,并对测量误差进行了分析.
The developing fundamentals of mearsuring set for DS 28 timing mechanism is introduced in this paper. The method of transforming singal from differnt level into TTL level by using optoisolator is proposed. The support measuring hardware and software are designed. Finally, the measuring errors have been analyzed.
