| description | In order to study the fire detection method of cable tunnel. We carried out physical experiments in the cable tunnel test section, using the heater pyrolyze PVC so that its pyrolysis as the ignition source obtained a total of 17 fire source location points in the horizontal and vertical directions of seven different fire detectors, and only processed the response time data of the alarm detector obtained the response time and the analysis results were drawn. With the increase of the distance from the fire source, the response time of each type of detector increases in different forms. It is found that the detection distance of the grating fiber temperature sensor is shorter, and the response time near the fire source is more stable. The detection performance of the point pyrolytic particle detector is more affected by the detection distance, which is advantageous for the detection point to have better response performance. The intelligent active suction detector is also affected by the detection distance, which is less affected than the point detector, the response time curve is more stable, and the detection performance is better at each test point.
