在微型计算机迅速普及、应用水平不断提高的今天,微机不但可以用于机车控制系统,而且可以用于内燃机车的参数识别、计算机数字仿真,故障诊断和机车运行状态的检测分析等研究领域。本文介绍了以IBM PC/XT微型计算机为中心的内燃机车数据采集系统的硬件电路设计、微弱信号的处理与传输技术以及软件设计的方法,为从事这方面研究工作的同志提供一些参考。
Microcomputer is not only used in locomotive control system, but also used in the field of parameter identification of diesel locomotive, computer digital simulation, fault diagnosis and detection and analysis of running status of locomotive. This article introduces the hardware circuit design, weak signal processing and transmission technology and software design method of diesel locomotive data acquisition system centered on IBM PC / XT microcomputers, and provides some references for the comrades working in this field.
