1、 1 摘要 机车安全运行，一直是人们非常重视和关注的问题，每台车机都有大修、中修、和入出 库检修等，机车上的仪器、仪表种类繁多，有些可以在机车停止时检测，有些必须在运行中 检测， 而以前后者的检测方法就是机车在线运行检测， 需要调度、 司机、 检测等多人员配合， 本课题是设计制作一台能够让机车在停止状态下提供速度信号让机车模拟运行状态， 方便机 车检修。 机车速度信号发生器就是对机车质量多种检测方式中的一种，它能对机车在静止状态 下， 模拟 机车光电传感器装置而发出模拟无线脉冲信号， 将信号传送至监控装置的主机箱， 监控装置主机箱再发送信号至监控装置显示器，从而随着操作者控制遥控发射增减速度指

2、 令， 速度信号发生器对应接收指令信号， 监控装置显示器对应显示遥控器所发射的增减速度 值， 以检验机车监控装置速度信号显示的作用是否良好， 它能快速方便地实施对机车监控系 统速度显示的诊断。 本文通过介绍各个模块的组成部分和工作原理，旨在阐述如何通过 51 单片机最小系统 及信号输出模块等，设计出一台能够模拟机车速度在 5-160km/h 之间的机车速度信号发生 器，方便机车的检修和维护。并说明其工作原理、工作方式、应用范围。 关键词: 机车检修 单片机 信号发生器 2 Abstract The safe operation of the Locomotive is that people

3、attaches great importance and concern. every locomotive need overhaul, repair, into and out of repair, etc. There are many different kinds of instruments, meters on a motorcycle, some during t he locomotive to stop testing, some must be in the running test. And before the latter detection method is

4、the locomotive running online detectio n, need scheduling, driver, testing and other personnel. The signal generator for locomotives is one of the many ways in detect. It can simulate locomotive light and electricity transducer to sent analog signal wireless pulse under the locomotive in the stage o

5、f stillness. It bring the signal to the main box of inspect device. Then the main box bring to display of inspect device. Thus by the operator control remote device to sent the dictate, the speed signal generator corresponding incept the speed value, so that to check up the stage of the signal appea

6、r good or bad of inspect device of locomotive, It can diagnose fast and convenience to inspect device of locomotive, This topic is to design a can let the locomotive speed signal in stop state provides for locomotive running state, a simulated locomotive maintenance convenience. In this paper, through the introduction of the component and working principle of eac h module, mainly discussed how to use single chip microcomputer minimum system a nd the signal output module and so on, to design
