智能化多功能测时仪研制

The design of intelligent multi-functional chronometer

研制了一种用单片机实现的测时仪 .该测时仪的四个输入通道分别记录该通道输入脉冲信号的时刻值 .配接线圈靶、天幕靶和光幕靶等区截装置 ,四个通道两两任意配对即可实现对飞行弹丸速度的测试 ,速度值可直接在仪器面板上显示 ;如果配接四个天幕靶 ,可实现弹丸着靶位置的测试 .本仪器既可室内使用 。

A chronometer which is realized by single chip computer was designed.The chronometer, which has four channels, records the time of input pulse from each channel. Connected with four intercepting devices, e g. coils target, sky screens and light screens, it was able to measure the flying bullet in any pairs of them. The final velocity was directly displayed on the panel. Connected with four sky screens,it can measure the position where the flying bullet touches on the target.The chronometer can be used not only in room but also in field.
