摘要： 目前轨道交通门控器定期检修维护尚无相应现场检测仪，现场手工测试效率低、准确性不高，并且要求对门控器设计原理很熟悉。该文在分析总结手工测试原理和业务逻辑的基础上，成功研制了基于ARM9＋Linux的移动式轨道交通门控器现场检修维护设备，使检测人员可以现场判定故障所在的具体元器件，对故障作出定量分析，介绍了系统结构、功能以及实现中的关键技术。

Abstract: At present, there is not the equipment to test railcar electro-door control unit on the spot. The efficiency and veracity is very low by hand-test, and tester is required to know well the design of railcar electro-door control unit. Based on the analysis of the principle and logic by hand-test, this paper designs the equipment with embedded CPU and Linux, so test man can easily make a quantitative analysis. The paper introduces the equipment’s structure, function and main technique.
