Description

Technical Field

[0001] The invention belongs to the technical field of tunnel fire management and relates to a fire emergency plan management method for a highway tunnel. Background Art

[0002] At present, highway traffic safety has long become a serious social problem in my country. Once a traffic accident occurs on a highway, especially in a tunnel, it will cause serious consequences and seriously endanger people's lives. In recent years, the exposure rate of tunnel safety accidents has become increasingly high, which has made the fire safety management of tunnels more and more concerned by the society. In 2012, the Ministry of Transport issued the "Technical Requirements for Highway Monitoring", proposing the need to build a traffic incident detection system.

[0003] There are many sources of tunnel fires. Tunnels are generally humid, which can easily accelerate the aging of various electrical equipment and lines, and is prone to problems such as short circuits and excessive local resistance. Since the tunnel space is relatively closed, in order to eliminate harmful gases and ensure ventilation, the wind speed in the tunnel is generally relatively high. Once a fire occurs, the fire spreads rapidly.

[0004] At present, in the emergency management of tunnel fires, when a fire occurs, firefighters rush to the scene to take measures after receiving the alarm, which often misses the best rescue opportunity and fails to carry out early rescue in time. Therefore, it is necessary to monitor and warn tunnel fires in real time and carry out emergency treatment for early fires. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, the present invention generates a tunnel fire emergency plan based on fire alarm information, reasonably guides highway managers to carry out fire rescue and disposal in the first time, and promptly takes corresponding emergency measures to minimize the losses of fire accidents. The present invention is achieved through the following technical solutions: The present invention provides a highway tunnel fire plan management method, including the following steps: S1 obtains fire alarm information; S2 formulates a corresponding fire emergency plan based on the fire alarm information, and the fire emergency plan includes an escape induction stage, a fire rescue and extinguishing stage, and a traffic restoration stage; S3 executes the fire emergency plan.

[0006] As a preferred solution, a fire alarm host, a temperature-sensitive grating and a fire alarm button are installed in the tunnel. The temperature-sensitive grating and the fire alarm button are electrically connected to the fire alarm host respectively. The fire alarm host is connected to the monitoring platform through a network protocol and exchanges data with it. When the temperature-sensitive grating or the alarm button is triggered, the monitoring system will obtain fire alarm information such as the status and location of the alarm equipment through the fire alarm host.

[0007] As a preferred solution, after the monitoring system obtains the alarm information from the fire alarm device, it transmits information such as the alarm device, alarm location and on-site monitoring video to the highway tunnel manager in the form of a sound alarm; after the manager confirms the actual occurrence of the fire through on-site monitoring video or emergency calls, the monitoring system will automatically formulate a fire emergency plan based on the confirmed fire location. The specific fire emergency plan methods include the escape induction stage, the rescue and fire extinguishing stage and the traffic restoration stage.

[0008] As the preferred solution, the traffic lights, lane indicators, tunnel lighting, fire pumps, rolling doors, fans and other equipment involved in the implementation of the fire emergency plan are all controlled by the monitoring system connected to the PLC controller, and the information board and broadcast are connected to the monitoring system through the network.

[0009] The beneficial effects of the present invention are:

[0010] The present invention generates a tunnel fire emergency plan according to the fire alarm information, reasonably guides the highway administrator to carry out the fire rescue disposal in the first time, takes corresponding emergency measures in time, and minimizes the losses caused by the fire accident.
