Background

The construction and management of the road tunnel enters into a repeat period. In the management of highway tunnel operation, tunnel fire is a type of safety accident with the greatest harm. In case of fire accident of highway tunnel, it will not only cause serious injury to driver and passengers in tunnel, but also will cause huge damage to tunnel lining structure, tunnel pavement and tunnel facilities. At the initial stage of a fire on a highway tunnel, whether drivers and passengers can safely evacuate depends on 2 time factors, namely the time required for the fire to develop into a danger for the drivers and passengers and the time required for the drivers and passengers to evacuate to a safe area. Only if the safe evacuation time is longer than the time required for evacuation to a safe area, the highway tunnel can be considered to be safe for the evacuation of the driver and passengers after the fire occurs. If the early flame of the fire of the highway tunnel can be effectively detected and early warning is carried out, the fire early warning device is not only beneficial to the safe evacuation of drivers and passengers, but also beneficial to the timely starting of fire-fighting equipment to inhibit the spread of fire, and the casualties and property loss caused by the fire are reduced to the maximum extent. In order to ensure the safe operation of the highway tunnel, it is necessary to timely identify and alarm all suspicious flames appearing in the tunnel.

The highway tunnel fire is mainly caused by various factors such as the failure of an electric line or equipment in the tunnel, the electromechanical failure of a vehicle, the traffic accident of an automobile, the ignition of a vehicle-mounted combustible or combustible material and the like. The traditional temperature-sensing fire flame detector is easily influenced by factors such as monitoring space area, height, dust, air velocity and the like, and is not beneficial to timely and effective detection of flame at the initial stage of tunnel fire. In the existing tunnel and subway fire alarm systems, the most applied fire detector products are mainly divided into two categories, namely a point type flame detector and a linear temperature-sensing fire detector. The point-type flame detectors are classified into infrared and ultraviolet flame detectors according to the spectral range. The principle is to judge whether the ignition point exists or not by detecting the flame distribution spectrum. The biggest problem in tunnel applications is the susceptibility to false alarms caused by interference from construction light sources such as sodium lamps, mercury lamps and electric welding arcs. The linear temperature-sensing fire detector comprises three types, namely a cable type, an air pipe type and an optical fiber temperature-sensing detector. The principle is that an alarm signal is generated by sensing the change of the ambient temperature. The main problem of the application in tunnels and subways is that effective alarming can not be carried out at the initial stage of fire occurrence.

With the development of artificial intelligence technology and the progress of image algorithm technology, the processing and understanding of video images gradually become the mainstream research direction of computer vision, the flame detection technology based on videos is more and more emphasized and researched, the detection technology can overcome the limitations of limited detection distance, slow response speed and the like of the traditional sensor, as long as flame appears in a video monitoring area, a flame detection program can immediately identify and output an alarm signal, and the detection is more accurate and rapid. The detection technology based on the video image is one of the most effective technologies for realizing the flame detection of the early fire of the highway tunnel at present.

With the development of traffic engineering construction and traffic industry in China, the mileage of traffic tunnels built in China is rapidly prolonged, and due to the ever-increasing traffic flow and road condition improvement and the complexity of article transportation, the risk probability of fire and tunnel abnormal events of the traffic tunnels is increased, and great threat is caused to traffic facilities and human production activities. The intelligent and information management of the tunnel is more and more important. With the rapid development of internet of things equipment and computer technology, a large amount of data of various conditions of the tunnel is accumulated in the intelligent construction process of the tunnel, and the management of how to effectively screen, clean, store, analyze and the like the data is very important. The method has great guiding significance for the intelligent construction of the tunnel at the present stage and in the future by establishing a data management platform integrating data acquisition, processing, storage, calculation analysis and application display.
