Development of microsecond time interval and action device

文章详细介绍了微秒级时间间隔发生及动作装置的设计思路、电路原理、仪器制作以及最终的功能实现。利用模拟电路、数字电路和单片机的知识,设计软硬件电路,利用高准确度晶振和分频、计数模块,发出标准时间间隔信号并且驱动继电器,模拟漏电保护器的分断动作,实现对漏电开关测试仪、机械开关特性测试仪等仪器动作特性的计量检测。

The thesis introduces in detail design ideas, circuit principle, instrument manufacture and function realization of microsecond time interval and action device. The design of software and hardware circuit are based on analog circuits, digital circuits and MCU.The device makes use of high accuracy crystal and divider and counter modules to give standard time interval signal and drive relays. And it imitates breaking action of leakage protector to fulfill measurement and detection of leakage switch tester and mechanical switch tester features.
