地鐵屏蔽門系統(tǒng)它沿地鐵站臺設(shè)置，在列車與站臺候車室安裝隔離的玻璃幕墻，只有在地鐵到站時，才會和列車門同開同閉，嚴絲合縫，這樣一來，乘客只能通過這道門進出列車，而不能到達軌道等有危險的地方;并且地鐵屏蔽門系統(tǒng)具有的節(jié)能、環(huán)保和安全功能，減少了站臺區(qū)與軌行區(qū)之間冷熱氣流的交換，降低了環(huán)控系統(tǒng)的運營能耗，從而節(jié)約了營運成本。是現(xiàn)代化地鐵工程的必備設(shè)施。
　工程概況
　　南京地鐵一號線全長21.72公里，南起河西新區(qū)奧體中心，經(jīng)小行、中華門、新街口、鼓樓、玄武門、南京火車站，止于邁皋橋站，共設(shè)車站16座，其中地下車站11座，地面及高架車站5座，貫穿南京市主城區(qū)南北向中軸線。
　　解決方案
　　地鐵車站的環(huán)境特殊，有較強的短期高電磁輻射現(xiàn)象存在。在充分考慮其可靠性、易維護性及可擴展性，并具備故障診斷、在線修改等功能要求下，結(jié)合工藝需求，對系統(tǒng)的軟硬件充分遵循模塊化和冗余設(shè)計的原則。根椐地鐵的特殊要求，采用施耐德電氣公司MODICON系列可編程序控制器，提供全冗余解決方案。施耐德電氣MODICON系列PLC在冗余技術(shù)上世界領(lǐng)先，提供極高的可靠性和世界一流的冗余技術(shù)。冗余的實現(xiàn)無需軟件編程，大大減少人為因素對熱備性能的影響。硬件系統(tǒng)采用模塊化的結(jié)構(gòu)，所有模塊和系統(tǒng)組件均能帶電插拔，實現(xiàn)現(xiàn)場區(qū)域控制器的配置，完成數(shù)據(jù)采集、實時控制、數(shù)據(jù)通訊的功能。保證了控制系統(tǒng)運行的連續(xù)性，大大提高了系統(tǒng)的整體安全可靠性。
　　屏蔽門控制系統(tǒng)網(wǎng)絡(luò)采用國頒標準MODBUS TCP/IP工業(yè)以太網(wǎng)技術(shù)，將 DCU作為網(wǎng)絡(luò)節(jié)點掛接在系統(tǒng)上，工業(yè)以太網(wǎng)的10M/100M的自適應(yīng)傳輸速度、高可靠的短幀傳輸充分滿足地鐵運營對安全門的工作要求，通過網(wǎng)絡(luò)上的監(jiān)控主機/DCU等設(shè)備實現(xiàn)對安全門的基本控制、參數(shù)修改、報警、顯示、監(jiān)控等功能。
