2.4火災發(fa)生控制

      火(huo)(huo)(huo)災(zai)發(fa)生(sheng)的(de)(de)(de)時間(jian)、地(di)點具有相(xiang)當的(de)(de)(de)不可預見(jian)性，具有破(po)壞性強(qiang)，危(wei)害嚴重，易造成秩序混亂等(deng)特點，也是城市軌道(dao)交通安(an)全防范(fan)的(de)(de)(de)主要事件之一。當車站(zhan)發(fa)生(sheng)火(huo)(huo)(huo)災(zai)時，智(zhi)慧安(an)防系(xi)(xi)(xi)統(tong)(tong)通過(guo)和綜合(he)監控(kong)系(xi)(xi)(xi)統(tong)(tong)的(de)(de)(de)融合(he)接口，迅速(su)定位火(huo)(huo)(huo)情(qing)發(fa)生(sheng)的(de)(de)(de)位置，通過(guo)視(shi)(shi)頻監控(kong)系(xi)(xi)(xi)統(tong)(tong)調取火(huo)(huo)(huo)災(zai)點的(de)(de)(de)現(xian)場(chang)視(shi)(shi)頻，按照設(she)定的(de)(de)(de)報警級別，發(fa)出(chu)聲光報警，記錄事件，界面顯(xian)示(shi)應急(ji)處理流程(cheng)，告知車站(zhan)管理人員(yuan)前(qian)往(wang)處理。同(tong)時系(xi)(xi)(xi)統(tong)(tong)實(shi)時聯動觸發(fa)公共廣(guang)播循(xun)環(huan)播放乘客疏散(san)語音(yin)，乘客信息(xi)系(xi)(xi)(xi)統(tong)(tong)顯(xian)示(shi)乘客疏散(san)信息(xi)，環(huan)境與設(she)備(bei)監控(kong)系(xi)(xi)(xi)統(tong)(tong)啟動相(xiang)應的(de)(de)(de)火(huo)(huo)(huo)災(zai)模(mo)式，自動售檢(jian)票系(xi)(xi)(xi)統(tong)(tong)打開(kai)閘機，視(shi)(shi)頻監控(kong)系(xi)(xi)(xi)統(tong)(tong)顯(xian)示(shi)火(huo)(huo)(huo)情(qing)區(qu)域、臨近區(qu)域、疏散(san)人員(yuan)的(de)(de)(de)圖像信息(xi)，門禁系(xi)(xi)(xi)統(tong)(tong)打開(kai)相(xiang)關(guan)

區域門禁，確保(bao)乘(cheng)客(ke)安(an)全有序的撤離。

3 對風(feng)管采取(qu)防火保護措(cuo)施

       需完(wan)善風管耐火(huo)試驗(yan)的相關標準，普通風管判定標準為完(wan)整性(xing)和隔熱性(xing)，消防風管判定標準為穩定性(xing)、完(wan)整性(xing)和隔熱性(xing)。

      應根據(ju)吊(diao)頂(ding)的(de)防火(huo)性能，決定是否縮(suo)短吊(diao)頂(ding)內風(feng)管的(de)耐火(huo)極(ji)限，且(qie)縮(suo)短時(shi)間不超過吊(diao)頂(ding)的(de)耐火(huo)極(ji)限。

      風管防(fang)火(huo)保護(hu)段不應開(kai)設風口，當(dang)開(kai)設風口時，此段風管可不設防(fang)火(huo)保護(hu)措施。

      軌道交通中(zhong)風管穿越防(fang)火分隔(ge)體(ti)(ti)處(chu)無(wu)論是否有防(fang)火閥(fa)，均應設防(fang)火保護措施，其耐(nai)火極限(xian)不低于分隔(ge)體(ti)(ti)的(de)耐(nai)火極限(xian)。
