| 摘 要： | 通过油盘火试验和模拟研究隧道火灾探测技术.油盘火试验分汽车下着火和汽车后方着火,模拟分为发动机舱着火和乘客舱着火.只有闭路电视图像探测器和感烟探测器能探测到车辆下方火灾,线型光纤感温探测系统探测车辆后方火灾较快.探测系统对乘客舱火灾的响应时间比发动机舱火灾的响应时间长.以50 km/h行驶的移动车辆着火,所有探测器无响应.建议采用两种及以上技术进行探测.

| Abstract: | The fire detection in tunnel was researched by simulation and pool fire experiment.Pool fire experiments of fire under the car or fire behind the car were done and the fire in engine cabin or passenger cabin was simulated.Only closed circuit television image detector and smoke detector can detect the fire under the car.Response time of detector by fire in passenger cabin is longer than that in engine cabin.All kinds of detector have no response to fire in a car which moving at 50 km/h.2 and more kinds of de... |
