Design of A Intelligent Monitoring Instrument of Breakthrough Status in Train pipe

文章介绍了以 89C51为核心所组成的智能化列车管贯通状态监测仪的工程设计与实现，它能在机车的正常运行中自动显示出列车管内压力和差压的动态参数，并能实现系统的实时校准和测量数据的误差修正。

This paper introduces our research work of a intelligent monitoring instrument of the breakthrough status in the train pipe base on 89C51 micro－ controller.The dynamic characteristics of the pressure and differential pressure in the train pipe is automaticaly displayed.By the micro－ controller dealing with the signal from sensor,the real－ time self－ calibration and the error compensation is realized.
