高速测量电子线路的设计

A Design for High-speed Measuring Electronic Circuit

介绍了弹射试验中的非接触式高速测量电路系统的核心部分——速度信号测量电子线路的设计。该电路的原理是通过触发移位寄存器使其输出一组编码,根据接收器所接收到的编码来判断滑行的距离,由计算机所记录的时间就可以计算出此处的速度。

This paper introduces the nuclear part of contactless high-speed measuring system of the e-ective experimentation--the design for speed signal measuring electronic circuit. Contactless highspeed measuring system is mainly designed for intelligentization and detection precision of plane＇s speed measuring. The designing principle of the system is showed as follows. The speed of a specified point can be calculated according to the time recorded by a computer and the sliding distance identified by a set of outputcode from a triggered shift register received by a receptor.
