一、地鐵屏蔽門系統的組成有哪些
地鐵屏蔽門系(xi)(xi)統由機(ji)械和電(dian)氣(qi)兩部分構(gou)成(cheng),機(ji)械部分包括(kuo)門(men)體(ti)結構(gou)和門(men)機(ji)系(xi)(xi)統,電(dian)氣(qi)部分包括(kuo)電(dian)源系(xi)(xi)統和控(kong)制(zhi)系(xi)(xi)統。主要(yao)構(gou)成(cheng)部分有:門(men)體(ti)結構(gou)、門(men)機(ji)系(xi)(xi)統、門(men)機(ji)控(kong)制(zhi)器(DCU)、車站級控(kong)制(zhi)、監視系(xi)(xi)統。屏蔽門(men)門(men)體(ti)結構(gou)通(tong)常由滑動門(men)、固定門(men)、應(ying)急(ji)門(men)、端頭門(men)及門(men)機(ji)頂(ding)箱、踏步板、上下(xia)部連接結構(gou)等構(gou)成(cheng)。
其中(zhong)門(men)機(ji)是由驅(qu)動機(ji)構、傳動機(ji)構、懸(xuan)掛機(ji)構、鎖(suo)定解鎖(suo)機(ji)構組成。電(dian)機(ji)在門(men)機(ji)控(kong)制(zhi)(zhi)(zhi)器(DcU)的控(kong)制(zhi)(zhi)(zhi)下,通(tong)過螺(luo)桿或皮帶傳動來實現滑動門(men)的開關運動。屏蔽門(men)控(kong)制(zhi)(zhi)(zhi)系統設(she)備由中(zhong)央控(kong)制(zhi)(zhi)(zhi)盤(pan)(PSC)、遠程監視設(she)備(PSA)、就地(di)控(kong)制(zhi)(zhi)(zhi)盤(pan)(PSL)、緊急控(kong)制(zhi)(zhi)(zhi)盤(pan)(IBP)、門(men)機(ji)控(kong)制(zhi)(zhi)(zhi)器(DCU)、就地(di)控(kong)制(zhi)(zhi)(zhi)盒(LCB)組成。
二、地鐵屏蔽門主要有哪些作用
1、系統控制功能
系統級控制是在地鐵屏蔽門正常運行模式下由信號系統(SIG)直接對屏蔽門進行控制的方式。在系統級控制方式下,列車到站并停在允許的誤差范圍內時(如:±300mm),信號系統向屏蔽門每側單元控制器(PEDC)發送“長/短車開/關門”命令,單元控制器(PEDC)通過門控單元(DCU)對每扇滑動門進行實時控制,實現屏蔽門的系統級控制操作。單元控制器(PEDC)與門控單元(DCU)通過可靠的硬線連接。站臺級控制是由列車駕駛員或站務人員在站臺的就地控制盤(PSL)上對屏蔽門進行“開/關門”的控制方式。當系統級控制不能正常實現時,列車駕駛員或站務人員可在就地控制盤(PSL)上通過“專用鑰匙”及”開/關門按鈕”對屏蔽門進行“開/關門”操作,實現屏蔽門的(de)站(zhan)臺級控制操(cao)作(zuo)。
2、監視功能
主(zhu)監(jian)(jian)(jian)視系(xi)統(MMS)是(shi)中央接(jie)口盤(pan)(PSC)核心部分(fen),完成每側屏(ping)(ping)蔽門(men)(men)(men)(men)單(dan)(dan)(dan)元(yuan)(yuan)相(xiang)關信(xin)息(xi)的(de)集成。包括收集PSC,PSL,IBP 以及屏(ping)(ping)蔽門(men)(men)(men)(men)電源的(de)信(xin)息(xi),屏(ping)(ping)蔽門(men)(men)(men)(men)故障(zhang)警報儲(chu)存(cun),屏(ping)(ping)蔽門(men)(men)(men)(men)正常系(xi)統運行記錄等。單(dan)(dan)(dan)元(yuan)(yuan)控(kong)制器(qi)(qi)(PEDC)與主(zhu)監(jian)(jian)(jian)視系(xi)統(MMS)之間的(de)監(jian)(jian)(jian)測信(xin)號通(tong)過(guo)可靠(kao)的(de)硬線(xian)來(lai)連(lian)接(jie),每個單(dan)(dan)(dan)元(yuan)(yuan)控(kong)制器(qi)(qi)(PEDC)將為主(zhu)監(jian)(jian)(jian)視系(xi)統(MMS)的(de)邏輯輸入(ru)模塊提供其操(cao)作狀(zhuang)(zhuang)(zhuang)態(邏輯電平信(xin)號),由(you)主(zhu)監(jian)(jian)(jian)視系(xi)統(MMS)監(jian)(jian)(jian)測屏(ping)(ping)蔽門(men)(men)(men)(men)系(xi)統的(de)基本操(cao)作狀(zhuang)(zhuang)(zhuang)態。門(men)(men)(men)(men)控(kong)單(dan)(dan)(dan)元(yuan)(yuan)(DCU)與主(zhu)監(jian)(jian)(jian)視系(xi)統(MMS)之間的(de)監(jian)(jian)(jian)視是(shi)通(tong)過(guo)使(shi)用通(tong)訊網絡(現(xian)場總線(xian))來(lai)實現(xian)的(de)。每個門(men)(men)(men)(men)控(kong)單(dan)(dan)(dan)元(yuan)(yuan)(DCU)在(zai)網絡上(shang)都(dou)有(you)一個唯一的(de)地(di)址,工(gong)程上(shang),為了便于管理和標識(shi),每個門(men)(men)(men)(men)控(kong)單(dan)(dan)(dan)元(yuan)(yuan)(DCU)的(de)地(di)址可取(qu)決于門(men)(men)(men)(men)控(kong)單(dan)(dan)(dan)元(yuan)(yuan)(DCU)在(zai)站(zhan)臺上(shang)的(de)位置(上(shang)/下行線(xian)、門(men)(men)(men)(men)單(dan)(dan)(dan)元(yuan)(yuan)號)。由(you)主(zhu)監(jian)(jian)(jian)視系(xi)統(MMS)監(jian)(jian)(jian)測門(men)(men)(men)(men)控(kong)單(dan)(dan)(dan)元(yuan)(yuan)(DCU)的(de)相(xiang)關狀(zhuang)(zhuang)(zhuang)態信(xin)息(xi)。
