地铁屏蔽门系统它沿地铁站台设置，在列车与站台候车室安装隔离的玻璃幕墙，只有在地铁到站时，才会和列车门同开同闭，严丝合缝，这样一来，乘客只能通过这道门进出列车，而不能到达轨道等有危险的地方;并且地铁屏蔽门系统具有的节能、环保和安全功能，减少了站台区与轨行区之间冷热气流的交换，降低了环控系统的运营能耗，从而节约了营运成本。是现代化地铁工程的必备设施。
　工程概况
　　南京地铁一号线全长21.72公里，南起河西新区奥体中心，经小行、中华门、新街口、鼓楼、玄武门、南京火车站，止于迈皋桥站，共设车站16座，其中地下车站11座，地面及高架车站5座，贯穿南京市主城区南北向中轴线。
　　解决方案
　　地铁车站的环境特殊，有较强的短期高电磁辐射现象存在。在充分考虑其可靠性、易维护性及可扩展性，并具备故障诊断、在线修改等功能要求下，结合工艺需求，对系统的软硬件充分遵循模块化和冗余设计的原则。根椐地铁的特殊要求，采用施耐德电气公司MODICON系列可编程序控制器，提供全冗余解决方案。施耐德电气MODICON系列PLC在冗余技术上世界领先，提供极高的可靠性和世界一流的冗余技术。冗余的实现无需软件编程，大大减少人为因素对热备性能的影响。硬件系统采用模块化的结构，所有模块和系统组件均能带电插拔，实现现场区域控制器的配置，完成数据采集、实时控制、数据通讯的功能。保证了控制系统运行的连续性，大大提高了系统的整体安全可靠性。
　　屏蔽门控制系统网络采用国颁标准MODBUS TCP/IP工业以太网技术，将 DCU作为网络节点挂接在系统上，工业以太网的10M/100M的自适应传输速度、高可靠的短帧传输充分满足地铁运营对安全门的工作要求，通过网络上的监控主机/DCU等设备实现对安全门的基本控制、参数修改、报警、显示、监控等功能。
