[0002] A coal mining area refers to a geographical area rich in coal resources where coal mining is being carried out or is planned. A coal mining area usually includes related facilities on the ground and underground mine systems. Coal mining areas can be located in mountainous areas, plains or hilly areas, usually near rich coal deposits.

[0003] At present, coal mines have installed a variety of multi-channel real-time cameras for safety monitoring, but for fixed area and mobile equipment area monitoring, they mainly rely on safety training and manual review of monitoring videos for inspection. The main problem with the existing solutions is that they rely on human resources and cannot achieve real-time monitoring, early warning and alarm functions, and the effect is not good. Moreover, most of the current monitoring is only for one side. If an accident occurs in a coal mine, it is likely to cause changes in the entire area. Therefore, the current monitoring method is unreasonable. Summary of the invention

[0047] The embodiment of the present invention solves the unreasonable technical problem of the current safety management and control method for coal mine areas in the prior art by providing a coal mine area safety management and control method.

[0048] The technical solution of the present invention is to solve the above technical problems, and the overall idea is as follows:

[0049] A method for safety management and control of coal mine areas, the method comprising: dividing a target mining area according to regional characteristics of the target mining area to obtain a plurality of sub-areas, wherein the types of sub-areas include: excavation area, transportation area, electromechanical area, ventilation area, drainage area and mining area; obtaining a first real-time video and a second real-time video of each sub-area, wherein the first real-time video is a video of a fixed angle, and the second real-time video is a video of tracking a dynamic target, wherein the dynamic target includes a dynamic object and a dynamic vehicle; generating a safety alarm event of the target mining area when any of the following conditions is met, and sending the safety alarm event to all clients in the target mining area, including: traversing a plurality of sub-areas, when the sum of the danger levels of the plurality of sub-areas is greater than a preset danger level threshold; or, respectively setting a safety distance threshold for each sub-area, when the real-time distance between the dynamic object and the dynamic vehicle in the sub-area is lower than the safety distance threshold corresponding to the sub-area; or, when the sum of the screen area proportions of the dynamic targets of the plurality of first real-time videos and the second real-time videos is greater than a preset screen area proportion.

[0050] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0051] First of all, the term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0052] The present invention provides Figure 1 A method for safety management and control of coal mine areas is shown, comprising steps S11-S13:

[0053] Regarding step S11, the target mining area is divided according to the regional characteristics of the target mining area to obtain several sub-areas, wherein the types of sub-areas include: excavation area, transportation area, electromechanical area, ventilation area, drainage area and mining area.

[0054] The target mining area refers to the coal mining area with safety control needs. Before coal mining, the entire mining area can be divided into several functional sub-areas according to regional characteristics, which is helpful to optimize resource allocation and improve work efficiency. Among them, regional characteristics can refer to the geographical location, geological characteristics and mining needs of the target mining area. The target mining area can include the excavation area, transportation area, electromechanical area, ventilation area, drainage area and mining area.

[0055] Excavation area: responsible for excavating new tunnels to provide channels for coal mining; transportation area: responsible for the transportation of coal and other materials within the mine; electromechanical area: responsible for the maintenance and operation of mechanical equipment in the mine; ventilation area: responsible for the ventilation system of the mine to ensure good air circulation; drainage area: responsible for removing accumulated water in the mine; within each stage or mining level, mining blocks with independent production systems are divided along the direction of the coal seam, which are called mining areas (for nearly horizontal coal seams, mining areas are sometimes called panel areas; for inclined longwall strip mining, they are called belt areas).

[0056] Regarding step S12, a first real-time video and a second real-time video of each sub-area are obtained, wherein the first real-time video is a video of a fixed angle, and the second real-time video is a video of tracking a dynamic target, wherein the dynamic target includes a dynamic object and a dynamic vehicle.

[0057] Video surveillance systems can be set up in different sub-areas of the target mining area to obtain two types of real-time video streams, one is video shot from a fixed angle, and the other is video that can automatically track dynamic targets such as moving personnel and moving vehicles.

[0058] The first real-time video is taken by a camera installed in a fixed position. The angle of the camera does not change. It is suitable for situations where you need to continuously focus on a specific area, such as an entrance, around important equipment, or at a key intersection.

[0059] The second real-time video is shot by a camera with automatic tracking function. The camera can rotate and translate with the moving dynamic target to keep the dynamic target in the picture. The dynamic targets include:

[0060] Dynamic objects: refers to people who are moving, for example, miners at work;

[0061] Dynamic vehicles: refers to various vehicles traveling in the mining area, such as mine cars, transport trucks, forklifts, etc.

[0062] Regarding step S13, when any one of conditions [1] to [3] is met, a security alarm event of the target mining area is generated, and the security alarm event is sent to all clients in the target mining area, wherein the security alarm event of the target mining area includes the event content, the time of the event, and the location of the event, including:

[0063] [Condition 1]: Traverse a number of sub-areas. When the sum of the danger levels of several sub-areas is greater than the preset danger level threshold, a safety alarm event for the target mining area is generated, including:

[0064] The regional parameters of each sub-area are obtained, wherein the regional parameters of each sub-area include: the excavation speed for the excavation area, the average speed of the dynamic target for the transportation area, the percentage of the number of equipment failures for the electromechanical area, the inverse of the air exchange flow rate for the ventilation area, the inverse of the drainage flow rate for the drainage area, and the coal mining speed for the mining area; corresponding weights are set for each sub-area; a number of sub-areas are traversed, and the danger level of the sub-area is determined according to the regional parameters of the sub-area and the weight of the sub-area; when the sum of the danger levels of any number of sub-areas is greater than a preset danger level threshold, a safety alarm event of the target mining area is generated.

[0065] Excavation area - Excavation speed: Indicates the speed of excavation work, which may be measured in meters per hour or meters per day. Excessive excavation speed may mean that workers are overloaded and increase the risk of accidents.

[0066] Transport zone - average speed of dynamic targets: refers to the average speed of all vehicles and personnel moving in the transport zone. If the speed is too fast, the risk of collision may increase.

[0067] Mechanical and electrical area - percentage of equipment failures: determines the proportion of equipment failures within a preset time period. The higher the failure rate, the more likely the mechanical and electrical equipment is to be improperly maintained, posing a safety hazard.

[0068] Ventilation area - the inverse of air flow rate: The air flow rate is the amount of air exchange per unit time. The smaller the air flow rate, the larger the inverse of the air flow rate, indicating that the ventilation effect is poor, which may lead to the accumulation of toxic gases.

[0069] Drainage area - the inverse of drainage flow: The drainage flow is the amount of water discharged per unit time. The smaller the drainage flow, the larger the inverse of the drainage flow. A low drainage rate may mean that the accumulated water is difficult to discharge in time, and there is a risk of flooding.

[0070] Mining area-coal mining speed: refers to the speed of coal mining. The higher the coal mining speed, the worse the roof stability and the higher the risk of collapse.

[0071] According to the importance of each sub-region, a corresponding weight can be set for each sub-region. For each sub-region, the danger level of the sub-region is calculated according to its regional parameters and the assigned weight, where danger level = (parameter value × weight).

[0072] Continuously and randomly traverse several sub-areas. If the sum of the danger levels of any number of sub-areas exceeds the preset threshold, it means that the overall risk of the target mining area is high. A safety alarm event for the target mining area can be generated and sent to all clients in the target mining area to remind all staff in the target mining area to pay attention to safety.

[0073] It can be understood that, compared with the prior art, the present invention does not carry out safety management for a single risk, but rather provides early warning for the overall safety of the target mining area. In addition, the present invention does not need to sum all factors. As long as the sum of the danger levels of any number of sub-areas exceeds the preset threshold at the same time, an alarm can be issued, and its alarm efficiency is higher.

[0074] [Condition 2]: Set a safety distance threshold for each sub-area. When the real-time distance between the dynamic object and the dynamic vehicle in the sub-area is lower than the safety distance threshold corresponding to the sub-area, a safety alarm event for the target mining area is generated, including:

[0075] The real-time distance between the dynamic objects and the dynamic vehicles in each sub-area is obtained from the first real-time video and the second real-time video of the sub-area; when the real-time distance between any dynamic object and any dynamic vehicle in the sub-area is lower than the safety distance threshold corresponding to the sub-area, a safety alarm event of the target mining area is generated.

[0076] First real-time video: Video streams from fixed-angle cameras that are placed at strategic locations in the mine to provide continuous field of view coverage.

[0077] Second real-time video: from a camera that can automatically track dynamic targets (such as workers and vehicles). The camera adjusts the viewing angle based on the movement of the target to ensure that the target is always in the picture.

[0078] Computer vision technology (such as image processing algorithms, machine learning models, etc.) is used to analyze these two types of videos, identify dynamic objects and dynamic vehicles in the picture, determine the positions of dynamic targets in the picture through image recognition technology, and use methods such as spatial coordinate transformation to estimate the actual distance between them.

[0079] The safety distance threshold set for each sub-area can be determined according to actual conditions. When the real-time distance between any pair of dynamic objects and dynamic vehicles is lower than the safety distance threshold, a safety alarm event can be generated immediately. The safety warning based on video analysis can improve the safety of coal mine operations and reduce work-related accidents caused by close contact.

[0080] [Condition 3]: When the sum of the screen area ratios of the dynamic targets in the first real-time videos and the second real-time videos is greater than the preset screen area ratio, a safety alarm event for the target mining area is generated, including:

[0081] Traverse all first real-time videos and all second real-time videos of all sub-areas, obtain the real-time image of the first real-time video and the real-time image of the second real-time video at any moment; determine the screen area ratio of the dynamic target in each real-time image, including: determining the sum of the screen areas of all dynamic targets in the real-time image; determining the screen area ratio of the dynamic target in the real-time image according to the ratio of the sum of the screen areas of all dynamic targets in the real-time image to the screen area of ​​the real-time image; traverse all real-time images at this moment, if the sum of the screen area ratios of any number of real-time images is greater than the preset screen area ratio, generate a safety alarm event for the target mining area.

[0082] First, all dynamic targets are identified from real-time images through computer vision techniques (such as motion detection, target tracking, etc.). For each identified dynamic target, the number of pixels it occupies in the image is calculated, which can be regarded as the screen area of ​​the target. The screen areas of all dynamic targets in the same image are added together to obtain the sum of the screen areas of all dynamic targets in this image.

[0083] The screen area ratio of the dynamic objects in the image is calculated based on the ratio of the sum of the screen areas of all dynamic objects in the image to the screen area of ​​the entire image (ie, the total number of pixels in the image).

[0084] Acquire multiple real-time images at a certain moment (for example, images from different cameras), perform the above-mentioned screen area ratio calculation on each image, add up the screen area ratios of all images at that moment, and obtain the total screen area ratio.

[0085] Randomly traverse the sum of the area proportions of any number of screens. When the sum of the area proportions of any number of screens (all referring to the real-time images at the same time) is greater than the preset area proportion, the mining area may be crowded or abnormal. When a large number of dynamic targets appear in a limited space, it may cause congestion and increase the risk of collision or accidents.

[0086] The present invention does not need to sum up all screen area ratios. As long as the sum of any number of screen area ratios is greater than a preset screen area ratio at the same time, an alarm can be issued, and its alarm efficiency is higher.

[0087] In order to further improve safety, it also includes: generating an audible and visual alarm signal when the number of safety alarm events generated in the target mining area within a preset time period is greater than a preset event number threshold.

[0088] In summary, the present invention provides a method for safety management and control of coal mine areas, the method comprising: dividing the target mining area according to the regional characteristics of the target mining area to obtain a number of sub-areas, wherein the types of sub-areas include: excavation area, transportation area, electromechanical area, ventilation area, drainage area and mining area; obtaining a first real-time video and a second real-time video of each sub-area, wherein the first real-time video is a fixed-angle video and the second real-time video is a video for tracking dynamic targets, wherein the dynamic targets include dynamic objects and dynamic vehicles; when any of the following conditions is met, a safety alarm event of the target mining area is generated, and the safety alarm event is sent to all clients in the target mining area, including: traversing a number of sub-areas, when the sum of the danger levels of the sub-areas is greater than a preset danger level threshold; or, setting a safety distance threshold for each sub-area, when the real-time distance between the dynamic object and the dynamic vehicle in the sub-area is lower than the safety distance threshold corresponding to the sub-area; or, when the sum of the screen area proportions of the dynamic targets of the first real-time videos and the second real-time videos is greater than the preset screen area proportion. Compared with the prior art, the present invention does not perform safety management for a single risk, but rather provides an early warning for the overall safety of the target mining area. In addition, the present invention does not need to sum all factors. As long as the sum of the danger levels of any number of sub-areas exceeds the preset threshold at the same time, an alarm can be issued, and its alarm efficiency is higher. The present invention does not need to sum all screen area ratios. As long as the sum of the screen area ratios of any number of screens at the same time is greater than the preset screen area ratio, an alarm can be issued, and its alarm efficiency is higher. The safety early warning based on video analysis of the present invention can improve the safety of coal mine operations and reduce industrial accidents caused by close contact.
