摘　　要：介绍一种高精度时间自动测量装置实现的原理和方法,并给出测量装置的软硬件设计原理框图,测量装置首先对输入被测信号进行信号调理,然后和启动信号一起送入高速AD采集卡采集,将采集后的数据通过CPCI总线送到主板进行数据分析,计算出两路信号某两点之间的时间值;测量装置的研制解决了以往测量耗时长、精度低,各项功能和性能指标已达到技术指标要求。This paper introduced an automatic high precision time measurement hardware and software design method. The measurement device did the signals device, and expounded the regulation of the input sig- nal, and then sent it with the start signal to the high speed AD acquisition card, finally analyzed the ac- quired data collected through the CPCI bus from motherboard and calculated out between two signals＇ time value. The measurement device solved the problem of time-consuming, low precision for previous system, all function and performance parameters of the device has already reached the technical requirements of the users.
