基于C51语言智能测时仪的设计与实现

The design of intelligent electrical chronometer based on C51 language

基于单片机高级语言C51设计了可与光幕靶、天幕靶等曲截装置组成弹丸速度测试系统的测时仪器,介绍了该仪器的工作原理以及基于CPLD设计的硬件组成电路和基于C51语言设计的软件流程结构.测时仪配接相应的曲截装置后,可完成4个通道两路测时.靶距通过测时仪器面板装入,弹丸速度值通过仪器面板直接显示.经靶场实弹射击验证,仪器工作性能稳定可靠,效果良好.

The system of the velocity measurement is made up of the electronic chronometer and the light screens or the sky-screens. The electronic chronometer based on C51 language uses the micro-controller unit and achieves two routes of time measurement with four channels. This paper introduces the principle of the electronic chronometer, the hardware circuit based on CPLD and the software flowchart based on C51. The distance between the two targets is inputinto the electronic chronometer by the panel, the velocity of projectile is directly displayed on the monitor. The experiment has proved that the electronic chronometer performs stably and accurately.
