城市轨道交通列车客室火灾主动预测报警装置布置方案研究

Layout Scheme of Active Predictive Alarm Device for Fire in Passenger Compartment on Urban Rail Transit Trains

研究了城市轨道交通列车客室火灾的特点,分析了不同探测器的适用性。对列车客室的防火设计进行建模,选取车厢中部座椅处发生汽油火灾和端部角落发生汽油火灾两种场景,并选取了3种探测器布置方案进行模拟研究,得到了不同场景下各布置方案的探测响应时间,给出建议的探测器布置方案。该建议方案经济、有效,可为列车客室的防火设计提供理论基础和实践依据。

The characteristics of fire in passenger compartment on urban rail transit trains are studied,and the applicability of different detectors is analyzed. The fire protection design of the train passenger compartment is modeled,and tw o fire scenarios are selected,namely seat gasoline fire in the middle of compartment and gasoline fire in end corners. Three detector layout schemes are selected for simulation research. The detection response time of each layout plan in different scenarios is obtained,and the suggested layout plan of detectors is given. The proposed scheme is economical and effective,providing a theoretical and practical basis for the fire protection design of train passenger compartments.
