摘　　要：为实现地铁车厢火灾自动报警,以西安地铁2号线B型车厢为研究对象,利用PyroSim软件进行数值模拟,比较地铁车厢内不同火灾场景下,红紫外火焰探测器不同数量、不同位置时的报警时间。结果表明,纵火火灾时探测器更早报警;设置3个火焰探测器A_1、B_1、C_1,B_1布置在地铁车厢顶的中间位置,A_1、C_1与B_1之间的距离均为3.5 m,为最优布置方案。In order to realize the automatic alarm of the subway car fire,this article takes the B-type carriage of Xi'an Metro Line 2 as the research object,and uses PyroSim for numerical simulation.The alarm time under different fire scenes in the subway cars,with different number and location of red UV flame detectors was compared.Results showed that the detector alarms earlier when the fire is arson;the optimal layout scheme is setting three flame detectors A1,B1,C1,while B1 are arranged in the middleof the top of the subway car,and the distance between A1,C1 and B1 is 3.5 m.
