摘　　要：基于国家标准规范的要求,在水下隧道可能出现危及两端或其他区段安全时,应设置防淹门,从而保护地铁设备以及人身安全。首先,介绍了地铁信号系统和防淹门系统接口的基础电气要求,以及分工界面和逻辑接口关于输入、输出的定义;其次,总结了信号系统需要实现的防淹门基本功能,在此基础上以一个常规站型为例,说明了在不同的控制模式下(基于通信的列车控制模式和联锁降级控制模式),防淹门状态丢失、请求关门、允许关门这3个故障场景下基本功能的具体实现,阐述了信号系统实现防淹门功能的基本设计原理;再次,在实际过程中,还需考虑项目的具体线路类型,如上下行是否连通,业主是否需要上下行联动等,以项目实际情况选择最终设计;最后,强调了防淹门功能是需要防淹门系统、信号系统,以及工作人员共同配合实现的一个安全功能。Based on the national standards and the requirement of metro equipment and personal safety protection,this paper introduces the floodgate(FGD)function in signaling system including their electrical definition and Input/Output of the logical interface.This paper summarizes the basic functions of the flood gate which need to be realized in the signal system.On this basis,a conventional station is taken as an example to illustrate the specific implementation of the function under three fault scenarios:loss of the flood gate state,request to close the door,permit to close the door,under different control modes(train control mode based on communication and interlock degradation control mode).The basic design principle of flood gate function in signal system is described.In the actual process,it is also necessary to consider the specific line type of the project,such as whether the upstream and downstream are connected,whether the owner needs upstream and downstream linkage,etc.,and select the final design according to the actual situation of the project.Finally,it is emphasized that the flood gate function is a safety function which needs the cooperation of the flood gate system,the signal system and the staff.
