Embodiment Construction

[0049] The structure and performance of the present invention will be further described below in conjunction with the accompanying drawings.

[0050] An intelligent collaborative linkage control method for downhole dampers based on video detection. The downhole camera is used as an information collection device to realize real-time monitoring of the damper area. The acquired video data is sent to the edge computing device for inference. Based on the graphics processing function of the edge reasoning device Realize the recognition of video content, including the recognition of target attributes (personnel recognition and vehicle recognition) and the monitoring of the damper status (open or close), the recognition result of the target attribute is combined with the damper control logic to generate a decision signal and send it to the PLC controller and generate monitoring feedback to the ground monitoring host to provide managers with visualized monitoring information. Based on ...

Abstract

The invention discloses an underground air door intelligent cooperative linkage control method for video detection, belongs to the technical field of intelligent monitoring, and aims to identify the real-time target type and detect the position of an air door area by utilizing an intelligent video monitoring technology and confirm the target attribute and the current passing requirement (pedestrians open small air doors and vehicles open large air doors) of the air door area. Therefore, intelligent opening and closing of the two air doors and efficient passage of the roadway are realized; logic locking of opening and closing of the two air doors is designed at the same time, the situation that the two air doors are opened and closed at the same time is limited in software function, and safety risks caused by human factors are eliminated fundamentally; in addition, in order to meet the personnel evacuation requirement under the emergency condition, a manual air door locking release button is arranged, and the personnel evacuation efficiency when an accident occurs is maximized.

Description

technical field [0001] The invention belongs to the technical field of intelligent monitoring, and relates to an intelligent cooperative linkage control method of an underground damper through video detection. Background technique [0002] The damper is the main ventilation facility in coal mines. It is often arranged in the roadway. Its main function is to ensure the stability of the ventilation system on the working face and reduce ineffective air leakage; to ensure that the underground personnel supply enough fresh air to meet the oxygen demand of the personnel; to dilute the toxic and harmful gases and Dust, to ensure safe production. If the underground damper is opened illegally due to various factors, the air flow in the mine may be disturbed, and the fresh air will directly enter the return air lane through the opened damper, causing the underground air points to fail to meet the air distribution plan, and the air volume at the mining face is insufficient, resulting i...
