Embodiment Construction

[0016] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0017] As shown in the accompanying drawings, a fire detection and positioning system for highway tunnels, including tunnel-specific fire detectors, a controller host, a distributed optical fiber temperature measurement system and a positioning system, the controller host is installed in the monitoring room, and is connected to the tunnel dedicated Fire detectors, distributed optical fiber temperature measurement system connection.

[0018] The detection parameters of the tunnel-specific fire detector include ultraviolet energy, infrared energy and video image information generated by flames and reflected by ground walls. The reflected active and weak ultraviolet and infrared energy does not require the flame to be directly exposed to the detector's...

Abstract

The invention discloses a system used for highway tunnel fire detection and positioning. The system comprises a tunnel-dedicated fire detector, a controller host machine, a distributed type optical fiber temperature measurement system and a positioning system. The controller host machine is installed in a monitor room, and is connected to the tunnel-dedicated fire detector and the distributed type optical fiber temperature measurement system. In the invention, in consideration of the problem that the flame is susceptible to the obstruction of a vehicle after a fire occurs in the highway tunnel, and the detection of the covered flame is realized by ultraviolet, infrared, optical fiber and image acquisition means, and the image identification means is used to realize the accurate positioning of the fire, so that the problem of fire extinguishing system linkage in the tunnel is solved.

Description

technical field [0001] The invention belongs to the technical field of tunnel fire detection equipment, in particular to a fire detection and positioning system for highway tunnels. Background technique [0002] Fires in highway tunnels are generally divided into two categories: vehicle fires and fires in ancillary facilities in tunnels. According to the investigation of previous tunnel fire cases in my country, vehicle fires in tunnels account for the vast majority of tunnel fires. When a vehicle fire occurs, the fire source is often located in the compartment or at the bottom of the compartment. For example, a passenger car fire often manifests as arson by personnel inside the compartment or burning of hazardous chemicals in the compartment. Fires caused by truck tires also occur from time to time. However, a fire inside or at the bottom of a vehicle is difficult to be detected by conventional ultraviolet or infrared flame detectors. In order to realize the detection of...
