接触网短路热循环实验多路温度测量开关切换装置

Realization of Multi-Way Switching Device Used in Shortcircuit and Heat Cycle Experiment of Catenary

讨论了一种基于 89C5 1的多路开关切换装置的实现方法。使用该装置可以对接触网短路热循环实验各个测温点进行循环测量。该装置具有完善的串行通信功能 ,在PC机上使用C + +Builder6 .0设计图形用户界面的控制软件 ,与多路开关装置进行串口通信 ,可以对开关切换的过程进行显示与控制。

In this paper, the design of a kind of multi-way switching device based on 89C51 is discussed in detail. Using this device can control the test point of contact line in shortcircuit and heat cycle experiment of catenary, as a result, the temperature of contact line can be measured. This device has perfect function of serial-port communication, and the software, which can communicate with serial port of multi-way switching device and can display and control the process of switching, of graphical user interface is designed by using C++ builder 6.0 in PC. Field running shows that this device is stable and reliable.
