一、地鐵屏蔽門系統的組成有哪些
地鐵屏蔽門系(xi)統(tong)(tong)(tong)由機(ji)械(xie)和電氣兩部分(fen)構(gou)(gou)成,機(ji)械(xie)部分(fen)包括門(men)體(ti)結(jie)構(gou)(gou)和門(men)機(ji)系(xi)統(tong)(tong)(tong),電氣部分(fen)包括電源系(xi)統(tong)(tong)(tong)和控制系(xi)統(tong)(tong)(tong)。主(zhu)要構(gou)(gou)成部分(fen)有:門(men)體(ti)結(jie)構(gou)(gou)、門(men)機(ji)系(xi)統(tong)(tong)(tong)、門(men)機(ji)控制器(DCU)、車站級控制、監視系(xi)統(tong)(tong)(tong)。屏蔽門(men)門(men)體(ti)結(jie)構(gou)(gou)通(tong)常由滑動門(men)、固定(ding)門(men)、應急門(men)、端頭門(men)及(ji)門(men)機(ji)頂箱(xiang)、踏(ta)步板(ban)、上下部連接結(jie)構(gou)(gou)等構(gou)(gou)成。
其中門(men)(men)(men)機(ji)是由驅動(dong)機(ji)構(gou)、傳動(dong)機(ji)構(gou)、懸掛機(ji)構(gou)、鎖定解鎖機(ji)構(gou)組(zu)成。電機(ji)在門(men)(men)(men)機(ji)控(kong)(kong)制(zhi)器(DcU)的控(kong)(kong)制(zhi)下,通(tong)過螺桿(gan)或皮帶傳動(dong)來(lai)實現滑動(dong)門(men)(men)(men)的開(kai)關運動(dong)。屏蔽門(men)(men)(men)控(kong)(kong)制(zhi)系統設備(bei)由中央控(kong)(kong)制(zhi)盤(pan)(PSC)、遠程監視設備(bei)(PSA)、就地控(kong)(kong)制(zhi)盤(pan)(PSL)、緊急控(kong)(kong)制(zhi)盤(pan)(IBP)、門(men)(men)(men)機(ji)控(kong)(kong)制(zhi)器(DCU)、就地控(kong)(kong)制(zhi)盒(LCB)組(zu)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,實現屏蔽門的站(zhan)臺級控(kong)制操作。
2、監視功能
主(zhu)監(jian)(jian)視(shi)系(xi)(xi)統(tong)(MMS)是(shi)中(zhong)央接(jie)口(kou)盤(PSC)核心部分,完成每(mei)(mei)側屏蔽(bi)門單(dan)元(yuan)相關(guan)信(xin)(xin)(xin)息(xi)的(de)(de)(de)集成。包括收集PSC,PSL,IBP 以及屏蔽(bi)門電源(yuan)的(de)(de)(de)信(xin)(xin)(xin)息(xi),屏蔽(bi)門故(gu)障警報儲存,屏蔽(bi)門正(zheng)常系(xi)(xi)統(tong)運行記錄等。單(dan)元(yuan)控(kong)(kong)制器(qi)(PEDC)與主(zhu)監(jian)(jian)視(shi)系(xi)(xi)統(tong)(MMS)之(zhi)間的(de)(de)(de)監(jian)(jian)測信(xin)(xin)(xin)號(hao)通過(guo)可靠的(de)(de)(de)硬線來(lai)連接(jie),每(mei)(mei)個(ge)單(dan)元(yuan)控(kong)(kong)制器(qi)(PEDC)將為主(zhu)監(jian)(jian)視(shi)系(xi)(xi)統(tong)(MMS)的(de)(de)(de)邏輯輸入模塊提供其操作(zuo)狀態(邏輯電平(ping)信(xin)(xin)(xin)號(hao)),由主(zhu)監(jian)(jian)視(shi)系(xi)(xi)統(tong)(MMS)監(jian)(jian)測屏蔽(bi)門系(xi)(xi)統(tong)的(de)(de)(de)基本操作(zuo)狀態。門控(kong)(kong)單(dan)元(yuan)(DCU)與主(zhu)監(jian)(jian)視(shi)系(xi)(xi)統(tong)(MMS)之(zhi)間的(de)(de)(de)監(jian)(jian)視(shi)是(shi)通過(guo)使用通訊網(wang)絡(現(xian)場總線)來(lai)實(shi)現(xian)的(de)(de)(de)。每(mei)(mei)個(ge)門控(kong)(kong)單(dan)元(yuan)(DCU)在網(wang)絡上(shang)都有一(yi)個(ge)唯一(yi)的(de)(de)(de)地(di)址(zhi),工程(cheng)上(shang),為了便于管理和標識,每(mei)(mei)個(ge)門控(kong)(kong)單(dan)元(yuan)(DCU)的(de)(de)(de)地(di)址(zhi)可取(qu)決于門控(kong)(kong)單(dan)元(yuan)(DCU)在站臺上(shang)的(de)(de)(de)位置(上(shang)/下(xia)行線、門單(dan)元(yuan)號(hao))。由主(zhu)監(jian)(jian)視(shi)系(xi)(xi)統(tong)(MMS)監(jian)(jian)測門控(kong)(kong)單(dan)元(yuan)(DCU)的(de)(de)(de)相關(guan)狀態信(xin)(xin)(xin)息(xi)。
