Embodiment Construction

[0018] In the process of realizing the present application, the inventor found that the current pressurized air supply devices are installed at the ends of both sides of the safety evacuation passage. When a fire occurs in the middle of the tunnel roadway, the positive air pressure in the evacuation passage cannot be guaranteed in time, and there is smoke. The problem of air intrusion into safe evacuation routes.

[0019] In view of the above problems, the embodiment of the present application provides a tunnel safety system. By installing a smoke arresting device at each safety exit, no matter where a fire occurs in the tunnel roadway, the smoke arresting device can provide positive air pressure in time to prevent The smoke from the tunnel roadway invades the safe evacuation channel to ensure the safety of evacuation.

[0020] The solutions in the embodiments of the present application can be realized by using various computer languages, for example, the object-oriented progr...

Abstract

The embodiment of the invention provides a tunnel safety system. The system comprises a plurality of smoke blocking devices and a control device, wherein the smoke blocking devices are all electrically connected with the control device; the smoke blocking devices are arranged at safety exits respectively; the safety exits are arranged between a safety evacuation passage and a tunnel roadway; and the control device is used for controlling the smoke blocking devices to provide positive air pressure for the safety exits when a fire occurs on the tunnel roadway. By the adoption of the tunnel safety system, the smoke blocking devices are arranged at the safety exits, no matter where the fire occurs on the tunnel roadway, the smoke blocking devices can provide the positive air pressure in time, smoke of the tunnel roadway is prevented from invading the safety evacuation passage, and evacuation safety of people is guaranteed.

Description

technical field [0001] The present application relates to the technical field of tunnel safety, and in particular, relates to a tunnel safety system. Background technique [0002] The current tunnel is usually equipped with safe evacuation passages. When a fire occurs in the tunnel roadway, people can enter the safe evacuation passageway from the tunnel roadway to evacuate through the safety exit between the tunnel roadway and the safe evacuation passageway. [0003] Problems existing in the prior art: [0004] In order to ensure the safety of personnel evacuation, the safe evacuation passage needs to maintain a positive air pressure compared with the tunnel roadway, so as to prevent the smoke from intruding into the safe evacuation passage from the tunnel roadway. However, at present, the pressurized air supply device is installed at the ends of both sides of the safe evacuation passage. When a fire occurs in the middle of the tunnel roadway, the positive air pressure in t...
