Problems solved by technology

[0004] At present, the detection / detection of the tunnel protective door is mainly carried out by maintenance personnel within the time of the tunnel skylight. It is difficult to realize the real-time detection of the state of the tunnel protective door, and there is no way to judge the use status of the tunnel protective door and possible safety hazards in advance. This is extremely unfavorable for the safe application of the tunnel protective door and even the safe operation of the tunnel

Abstract

The invention discloses a method for detecting the state of a tunnel protective door based on image recognition, which belongs to the technical field of tunnel protective door detection. It sets a camera corresponding to the tunnel protective door, and sets a data transmission unit and an industrial computer corresponding to it, and utilizes the image of the tunnel protective door The real-time collection and fast processing of data can realize the rapid detection of the state of the tunnel protective door, and then realize the accurate judgment of the opening and closing state of the tunnel protective door. The image recognition-based tunnel protective door state detection method of the present invention has simple system setting and accurate determination, can realize unmanned patrol inspection of the tunnel protective door, ensure real-time performance and accuracy of tunnel protective door state detection, and improve tunnel protection The safety and reliability of the door can ensure the safe operation of the tunnel and reduce the maintenance cost of the tunnel protective door, which has good practical value and application prospect.

Description

technical field [0001] The invention belongs to the technical field of tunnel protective door detection, and in particular relates to a method for detecting the state of a tunnel protective door based on image recognition. Background technique [0002] With the rapid development of my country's railway network, the number of tunnels is increasing day by day, resulting in the application of tunnel protective doors becoming more and more common. In general, the tunnel protection door is set beside the track to separate the track area from the equipment cavern or evacuation passage. In order to ensure the safety of tunnel operation, it should be ensured that the tunnel protective door will never intrude into the train's operating limit. [0003] However, due to the piston wind effect generated in the tunnel when the train is running in the tunnel, the facade of the tunnel protective door will be subjected to repeated and high-intensity piston wind effect for a long time. Beca...
