Description

Technical Field

[0001] The invention belongs to the technical field of coal mine safety, and relates to a monitoring and early warning system for mine fire and a monitoring and early warning method thereof. Background Art

[0002] Mine fire refers to fires that occur in underground tunnels, working faces, chambers, goafs and other places in coal mines. Once a mine fire accident occurs, it will cause serious personal injury and property loss. Mine fires may also induce gas and coal dust explosions, thereby further expanding the degree and scope of disasters, greatly troubling coal mine fire rescue. Coal mine fire accident prevention is the foundation of coal mine safety production. Real-time and effective detection of coal mine fires can effectively prevent fires on the one hand, and detect fires early on the other hand. Rescue can be carried out when the intensity of coal mine fires is small, the scope is relatively small, and the spread is slow, thereby reducing losses and casualties.

[0003] The existing technical solution discloses a coal mine fire detection system, including a video acquisition module, a target detection module, a data processing module, a target recognition module and a fire alarm module. The video acquisition module is composed of a front-end camera and is used to perform real-time scanning of the underground environment. The target detection module is used to detect the smoke area from the acquired video image. The data processing module is used to perform grayscale processing and image enhancement processing on the detected suspicious smoke area. The target recognition module is used to extract and recognize features of the smoke area to determine whether a fire has occurred. The fire alarm module is used to sound an alarm when a fire is detected.

[0004] The existing technical solution also discloses a method and device for detecting and preventing external fires in underground coal mines. The method includes obtaining the temperature and multiple sensor data of the underground area of ​​the coal mine, the multiple sensor data including carbon monoxide concentration, smoke data and open flame data; judging whether the temperature warning conditions are met based on the temperature; using data fusion technology to process the temperature and multiple sensor data to obtain effective feature information; and making decisions and outputting judgment results based on the logical reasoning algorithm of the adaptive DS evidence theory on the effective feature information.

[0005] However, the existing technology still has problems such as single monitoring parameters, high false alarm rate, poor real-time performance, and imperfect early warning mechanism in the coal mine fire monitoring system. Therefore, it is very important to provide a mine fire monitoring and early warning system and a monitoring and early warning method thereof. Summary of the invention

[0006] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a monitoring and early warning system for mine fires and a monitoring and early warning method thereof. In the present invention, by providing specific settings for the monitoring and early warning system for mine fires, the functions of multi-parameter comprehensive monitoring, intelligent data analysis and efficient early warning mechanism are realized, so as to realize real-time monitoring and early warning of mine fires, and achieve fast early warning response, thereby ensuring safe production in mines.

[0007] To achieve this object, the present invention adopts the following technical solutions:

[0008] In a first aspect, the present invention provides a monitoring and early warning system for mine fires, including an underground tunnel, wherein the monitoring and early warning system comprises a video acquisition module, a sensor module, an early warning unit and a control unit, wherein the control unit is connected to the video acquisition module, the sensor module and the early warning unit respectively by wire or wirelessly;

[0009] The sensor module includes a temperature sensor, a smoke sensor, a carbon monoxide sensor, an oxygen sensor and a humidity sensor, and the video acquisition module is used to acquire and identify video images of fires in the mine;

[0010] The control unit includes a video analysis module, a processing module and an execution module. The video analysis module is electrically connected to the video acquisition module, and the execution module is electrically connected to the processing module and the early warning unit respectively.

[0011] In the present invention, by providing specific settings for the monitoring and early warning system for mine fires, the functions of multi-parameter comprehensive monitoring, intelligent data analysis and efficient early warning mechanism are realized, so as to realize real-time monitoring and early warning of mine fires, and the early warning response is fast to ensure safe production in mines.
