摘要
为了保证紧急情况下乘客的安全,地铁各车站均安装有紧急按钮,用于控制闸机的紧急放行。介绍了闸机紧急放行控制器系统构成和工作原理,分析了闸机异常放行的主要原因,并对紧急按钮采用常闭接点和常开接点的优缺点做了比较。使用常闭方式更能及时发现故障,保证紧急放行时能及时响应。
To ensure the safety of passsengers emergency conditions, every subway station is installed with emergen- cy button for the operation of AGM. In this paper, the structure of emergency open controller and its working principle are introduced, the main reasons for abnormal AGM open are analyzed, then the merits and demerits of NC （normal close） and NO （normal open） are compared. In adopting the NC mode, the working failure of AGM could be detected timely and thus the quick response of AGM in emergency conditions could be ensured.
