Hardware Design of Subway Electrical Universal Tester

摘要:

地铁控制系统是一个庞大的电气控制系统,在控制系统中包含大量的控制电路和逻辑器件;在地铁系统出厂投入运行之前必须确保控制系统的安全性以及其逻辑功能的准确性,为此对控制系统中所有电气柜的检测是一个必不可少的工序;而以往大多采用人工检测方法,效率低也容易引起人为操作错误;为了能够高效、准确地对电气柜内的接线和元件的逻辑组态进行检测,文章研究并设计开发一种通用电气柜逻辑测试仪,测试仪提供1 000个普通测试点和10个大功率测试点,接线使用标准的接线器,检测操作简单、可靠性高;文章研制的测试仪已成功应用于地铁电气柜的测试中。

Abstract:

The subway control system is a large electrical control system, consisting of many control circuit and logic devices. Safety and accuracy must be ensured before the system is put into operation, so it is an essential procedure to check all electrical cabinets in the control system. While in the past the electrical cabinets were checked by labour, leading to inefficiency and misoperation. In order to improve the levels of efficiency and accuracy, the paper researches and designs a new universal electrical cabinet logic tester, which can provide 1 000 general test points and 10 high-power test points with standard connecter. Meanwhile the operation process is simple with high reliability. The tester has been applied in test of the subway electrical cabinets successfully.
