[0002] Non-coal mines are a high-risk industry, especially underground mines where problems in hoisting, ventilation, fire prevention, waterproofing, and open-pit mine slope protection can easily lead to major accidents. Particularly in economically underdeveloped areas, there is a lack of online information collection and monitoring systems for production enterprise risk points. This results in weak online monitoring and early warning capabilities for production risks and hidden dangers, failing to comprehensively, proactively, in real-time, and dynamically grasp all safety hazards. Existing monitoring systems often have low design standards, aging equipment, and inadequate safety monitoring facilities, resulting in insufficient safety assurance and risk mitigation capabilities to meet the demands of safe production in mining areas. Therefore, this invention proposes a satellite positioning-based safety production accident monitoring system and method. Summary of the Invention

[0017] Based on satellite radar positioning, the target is located within the satellite monitoring range of the mining area. A second mark is added to the mineral deposit satellite image. The second mark is compared with the first mark. When the first mark and the second mark are inconsistent, it is determined that illegal mining exists within the target satellite monitoring range. Based on satellite positioning, the illegal mining area is located and an illegal mining data packet is generated. The illegal mining data packet is sent to the secondary mining area management terminal.

[0018] Preferably, in a satellite positioning-based safety production accident monitoring system, the data analysis module includes:

[0019] The data processing unit is used to add tags to the acquired monitoring data, obtain the data storage path of the monitoring data corresponding to each monitored mining area based on the added tags, and send the monitoring data to the corresponding sub-storage space according to the data storage path.

[0020] The target determination unit is used to identify any monitored mining area as the target mining area and obtain the first monitoring data of the target mining area based on the sub-storage space.

[0033] The risk assessment subunit calculates the suitability of the current action based on the correspondence. When the suitability is lower than a preset value, it determines that there is a risk of a production accident in the worker's production operation.

[0034] Preferably, in a satellite-based safety production accident monitoring system, the behavior recognition subunit further includes:

[0035] The accident identification subunit is used to confirm whether workers in the production area can be properly positioned. If not, it is determined that a third-class accident has occurred in the target mining area.

[0036] The accident investigation subunit generates a worker distribution map after confirming that each worker in the production area can be located normally. Based on the worker distribution map, it determines whether there are any abnormal worker movements in the target mining area. If so, it obtains the actual environmental data of the production area of ​​the target mining area based on the target satellite and determines the environmental risk value corresponding to the production area. When the environmental risk value is greater than a preset value, it determines that a third-class accident has occurred in the target mining area.

The secondary mining area management terminal has a higher level than the primary mining area management terminal.

[0039] The second early warning unit is used to quickly locate the worker's position and send a safety warning to the primary mining area management terminal when there is a risk of a production accident during the worker's production operations in the target mining area.

[0052] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0053] Example 1:

[0054] This invention provides a satellite positioning-based safety production accident monitoring system, such as... Figure 1 As shown, it includes:

[0055] The satellite monitoring module is used to monitor the mining area within the monitoring area based on satellite data and obtain monitoring data.

[0056] The data analysis module is used to process the monitoring data to determine whether a production accident has occurred in the target mining area or whether there is a risk of a production accident.

[0057] The accident early warning module is used to quickly determine the location of the target mining area based on satellite positioning when a production accident occurs or there is a risk of a production accident in the target mining area, and send a safety warning to the mining area management terminal, which includes a primary mining area management terminal and a secondary mining area management terminal.

[0058] In this embodiment, monitoring data refers to satellite images acquired by the satellite.

[0059] In this embodiment, InSAR (Interferometry Synthetic Aperture Radar) monitoring technology is employed. This technology utilizes microwave (1 mm to 1 meter) phase differences generated from repeated observations of the Earth's surface using microwave synthetic aperture radar (SAR) image data to calculate surface deformation with millimeter-level accuracy. Synthetic aperture radar is characterized by high resolution, all-weather operation, and the ability to effectively identify camouflage and penetrate concealment.

[0060] In this embodiment, the primary mining area management terminal refers to the information receiving terminal of the mining area's own management system, while the secondary mining area management terminal refers to the information receiving terminal of the government's mining area management center's management system.

[0061] The beneficial effects of the above embodiments are as follows: This invention uses satellites to monitor mining areas and obtain monitoring data. After processing the monitoring data, it determines whether a production accident has occurred in the target mining area or whether there is a risk of a production accident. When a production accident occurs in the target mining area or there is a risk of a production accident, the system quickly determines the location of the target mining area based on satellite positioning and sends a safety warning to the mining area management terminal. This improves the real-time performance and comprehensiveness of mining area monitoring, eliminates the possibility of concealing mining accidents, and ensures the timeliness of accident detection. Furthermore, since the system is connected to both the enterprise's own management system and the government's management system, it can simultaneously investigate the risk of production accidents caused by workers' production operations while investigating mining accidents, thereby reducing the enterprise's accident rate.

[0062] Example 2:

[0063] Based on the above embodiment 1, the satellite monitoring module, such as Figure 2 As shown, it includes:

[0064] The range determination unit is used to determine the monitoring range of the satellite and the mining area data corresponding to the monitored mining area within the monitoring range, wherein the mining area data includes the location information of the monitored mining area and the land distribution information of the mining area.

[0065] The monitoring and control unit is used to control each satellite to monitor the monitored mining area within its corresponding monitoring range and obtain monitoring data.

[0066] The beneficial effects of the above embodiments are as follows: When the monitoring area is large, the present invention can use multiple satellites to jointly complete the monitoring of the mining area within the entire area. The monitoring range of each satellite and the corresponding mining area data of the monitored mining area within the monitoring range are determined. Each satellite is controlled to monitor the monitored mining area within its corresponding monitoring range and obtain monitoring data. Before obtaining the monitoring data, the monitoring objects of each satellite are confirmed and verified. This ensures that the monitoring objects of each satellite are accurate and that the mining area required by the system has corresponding satellites to collect monitoring data, thereby ensuring that accurate monitoring data is obtained.

[0067] Example 3:

[0068] Based on the above embodiment 2, the monitoring and control unit includes:

[0069] The signal transmission subunit is used to transmit mining area monitoring signals to the target satellite at preset time intervals.

[0070] The location calibration subunit is used to acquire the current panoramic image corresponding to the monitoring range of the target satellite after the target satellite receives the monitoring signal of the mining area, and to determine the location of the monitored mining area by making a first mark on the current panoramic image based on the mining area data corresponding to the monitored mining area within the monitoring range.

[0071] The monitoring subunit is used to focus on the current panoramic image locally based on the preset monitoring sequence and the location of the monitored mining area, and obtain the monitoring data of the monitored mining area one by one.

[0073] In this embodiment, the current panoramic image refers to the panoramic view of the entire monitoring range that the target satellite can capture at the current time.

[0074] In this embodiment, the first marker refers to marking the location of the monitored mining area on the current panoramic view, where the monitored mining area refers to a mining area where mineral resource extraction is legally carried out.

[0075] In this embodiment, local focusing refers to narrowing the satellite monitoring range from a panoramic view to the monitored mining area.

[0076] The beneficial effects of the above embodiments are as follows: The present invention sends mining area monitoring signals to the target satellite at preset time intervals. After the target satellite receives the mining area monitoring signals, it acquires the current panoramic image corresponding to the monitoring range of the target satellite. Based on the mining area data corresponding to the monitored mining area within the monitoring range, a first marker is added to the current panoramic image to determine the location of the monitored mining area and the location of the monitoring target, providing a basis for the target satellite to complete the orderly collection of monitoring data. Based on the preset monitoring sequence and the location of the monitored mining area, the current panoramic image is locally focused, and the monitoring data of each monitored mining area is obtained one by one, ensuring that the corresponding panoramic image of the entire monitored mining area can be accurately collected, facilitating the overall safety assessment of the monitored mining area enterprise.

[0077] Example 4:

[0078] Based on the above embodiment 3, the satellite monitoring module, such as Figure 2 As shown, it also includes:

[0079] The panoramic investigation unit is used to use the current panoramic image of the monitored mining area with the marked location as a reference image, and to mark the mineral deposits on the reference image based on the mineral deposit records stored in the database, thereby obtaining satellite images of the mineral deposits.

[0080] Based on satellite radar positioning, the target is located within the satellite monitoring range of the mining area. A second mark is added to the mineral deposit satellite image. The second mark is compared with the first mark. When the first mark and the second mark are inconsistent, it is determined that illegal mining exists within the target satellite monitoring range. Based on satellite positioning, the illegal mining area is located and an illegal mining data packet is generated. The illegal mining data packet is sent to the secondary mining area management terminal.

[0081] In this embodiment, the reference image refers to the current panoramic image of the target satellite where the location of the monitored mining area has been marked.

[0082] In this embodiment, the mineral deposit record refers to the location information of all non-coal mineral deposits existing within the target satellite monitoring range that are statistically analyzed and stored in the database in advance.

[0083] In this embodiment, the mineral deposit satellite image refers to the image obtained by marking mineral deposits on a reference image, and the mineral deposit markings are different colors from the first markings.

[0084] In this embodiment, the second marker refers to the location marker of the mine being mined (i.e., the mine being mined) on the mineral deposit satellite image within the target satellite monitoring range. The color used for this marker is different from both the mineral deposit marker and the first marker.

[0085] In this embodiment, the illegal mining data packet contains a data packet containing the location information of the illegal mining area, which refers to a mine that is being illegally mined.

[0086] The beneficial effects of the above embodiments are as follows: During the process of panoramic satellite acquisition of the monitoring range, the target satellite of the present invention collects monitoring data of all mineral locations within the monitoring range, investigates whether there is illegal mining, and if illegal mining is determined to exist within the monitoring range of the target satellite, it generates illegal mining data packets based on satellite positioning to locate the illegal mining area, and sends the illegal mining data packets to the secondary mining area management terminal, thereby realizing full-area mineral mining monitoring within the monitoring range and avoiding production accidents caused by irregular operations of illegal mining.

[0087] Example 5:

[0088] Based on the above embodiment 1, the data analysis module, such as Figure 3 As shown, it includes:

[0089] The data processing unit is used to add tags to the acquired monitoring data, obtain the data storage path of the monitoring data corresponding to each monitored mining area based on the added tags, and send the monitoring data to the corresponding sub-storage space according to the data storage path.

[0090] The target determination unit is used to identify any monitored mining area as the target mining area and obtain the first monitoring data of the target mining area based on the sub-storage space.

[0091] The data processing unit is used to generate satellite images of the target mining area based on the first monitoring data, mark the preset effective range of the target mining area based on the functional area layout map of the target mining area, and determine the edge line of the mining area.

[0092] After color equalization of the satellite image, the first grayscale feature corresponding to the determined edge line of the mining area is obtained, and the second grayscale feature of the adjacent pixels outside the edge line is obtained. The first grayscale feature and the second grayscale feature are compared to determine whether the edge of the mining area has changed location.

[0093] When the edge of the mining area changes, it is determined that a Class I accident has occurred in the target mining area;

[0094] Otherwise, based on historical monitoring data, obtain the historical grayscale characteristics of the edge line of the target mining area, determine the grayscale change characteristics of the edge line of the mining area, and judge whether the target mining area has experienced geological subsidence;

[0095] When geological subsidence occurs in the target mining area, it is determined that a second type of accident has occurred in the target mining area.

[0096] In this embodiment, the sub-storage space refers to the storage location of the monitoring data corresponding to each monitored mining area, and each monitored mining area has a dedicated location in the storage space.

[0097] In this embodiment, the target mining area refers to any monitored mining area.

[0102] In this embodiment, the first grayscale feature refers to the grayscale value change feature corresponding to each pixel on the edge line of the mining area.

[0103] In this embodiment, the second grayscale feature refers to the feature of the adjacent pixels outside the edge line corresponding to the pixel point, where the adjacent pixels outside the edge line refer to the adjacent pixels outside the edge line of the mining area.

[0104] In this embodiment, determining that a Type I accident has occurred in the target mining area when the edge of the mining area changes means that the first grayscale feature is the same as the second grayscale feature. The first accident refers to the relocation of the enterprise's mining area, posing a risk of illegal relocation and potential over-mining leading to changes in the overall terrain.

[0105] In this embodiment, the second type of accident refers to the subsidence of the mining area terrain.

[0106] The beneficial effects of the above embodiments are as follows: The monitoring data acquired by the present invention is tagged, and the data storage path of the monitoring data corresponding to each monitored mining area is obtained based on the added tags. The monitoring data is sent to the corresponding sub-storage space according to the data storage path, ensuring the orderly storage of monitoring data and providing support for the rapid retrieval of monitoring data. At the same time, any monitored mining area is taken as the target mining area, and the first monitoring data of the target mining area is obtained based on the sub-storage space. Satellite images of the target mining area are generated based on the first monitoring data. According to the functional area layout map of the target mining area, the preset effective range of the target mining area is marked, and the edge line of the mining area is determined. After processing the satellite image, the overall terrain change of the target mining area is monitored based on the grayscale characteristics of the pixels on the edge line and the adjacent pixels outside the line, so as to promptly detect the illegal outward movement of the target mining area and the problem of terrain subsidence.

[0110] The region determination subunit is used to determine the production area based on the region division image, segment the satellite image, and obtain the sub-satellite image corresponding to the production area;

[0111] An image recognition subunit is used to perform image recognition on the sub-satellite image, obtain satellite image recognition results, and determine whether a production accident has occurred in the target mining area.

[0112] In this embodiment, the regional division image refers to the satellite image after dividing the target mining area into functional areas (e.g., living area, production area, management area, etc.).

[0113] In this embodiment, the production area refers to the production operation area within the target mining area where mineral deposits are mined.

[0114] In this embodiment, subsatellite images refer to satellite images of the production area corresponding to the target mining area.

[0115] The beneficial effects of the above embodiments are as follows: The present invention uses a region division subunit to grayscale the satellite image of the target mining area, establishes a grayscale co-occurrence matrix to obtain the texture feature value of the satellite image, and determines the division of each region of the target mining area based on the texture feature. The resulting region division image realizes the intelligent division of the functional areas of the target mining area, avoiding the situation where the functional area layout of the target mining area is consistent with the actual production situation of the production area and the target mining area due to internal regional adjustments by the enterprise for production needs. This ensures the accuracy of the acquisition of sub-satellite images. Through the image recognition subunit, the sub-satellite images are image recognized to obtain the satellite image recognition results, determine whether a production accident has occurred in the target mining area, eliminate the possibility of concealing mining accidents, and ensure the timeliness of accident detection.

[0120] The risk assessment subunit calculates the suitability of the current action based on the correspondence. When the suitability is lower than a preset value, it determines that there is a risk of a production accident in the worker's production operation.

[0121] In this embodiment, the working environment characteristics refer to the environmental features within a small area preset on the sub-satellite image centered on the worker.

[0122] In this embodiment, production operation refers to the work that the worker is currently performing.

[0123] In this embodiment, the adaptability of the current action refers to the degree of compatibility between the worker's current action and the current production operation. The specific process is as follows:

[0124] First, based on the production operation currently being performed by the worker, a standard motion comparison chart of the current production operation is obtained from the database. Similar motions to the current operation are then selected from the standard motion comparison chart. After confirming that the number of motion vectors for the similar motions is the same as the number of motion vectors for the current operation, the fit is calculated.

[0125]

[0126] Among them, P q E represents the fit of the current action of the q-th worker in the subsatellite image; q μ represents the total number of action vectors for the current action of the q-th worker in the subsatellite image. q,j β represents the j-th action vector of the q-th worker's current action on the subsatellite image; q.j This represents the action vector μ that is similar to the action vector μ currently being performed by the q-th worker in the sub-satellite image. q,j Corresponding action vector; |μ q,j | represents the action vector μ q,j The modulus; |β q.j | represents the action vector β q.j The modulus; δ represents the motion capture error factor, with a value in (0, 0.1).

[0127] The beneficial effects of the above embodiments are: the present invention analyzes and judges the actions of each worker on the sub-satellite image to determine whether there is a risk of production accidents in the actual production operation of the workers, so as to help enterprises investigate the risk of production accidents caused by workers' production operations and reduce the accident rate of enterprises.

Based on the worker distribution map, it determines whether there are any abnormal worker movements in the target mining area. If so, it obtains the actual environmental data of the production area of ​​the target mining area based on the target satellite and determines the environmental risk value corresponding to the production area. When the environmental risk value is greater than a preset value, it determines that a third-class accident has occurred in the target mining area.

[0132] In this embodiment, normal positioning means that the target satellite can accurately locate the workers in the mining area.

[0140] The beneficial effects of the above embodiments are as follows: The present invention determines whether a production accident has occurred in the target mining area based on satellite positioning and worker actions, supplemented by on-site environmental data of the target mining area, ensuring the accuracy of the determination of potential production accidents, and also making up for the information lag caused by the difference between the time of the accident and the monitoring time.

[0141] Example 9:

[0142] Based on the above embodiment 1, the accident early warning module, such as Figure 4 As shown, it includes:

[0143] The first early warning unit is used to send a safety warning to the primary mining area management terminal and the secondary mining area management terminal simultaneously, based on satellite positioning of the target mining area location, when a production accident occurs in the target mining area. The production accident includes Class I accidents, Class II accidents, and Class III accidents. The secondary mining area management terminal has a higher level than the primary mining area management terminal.

[0144] The second early warning unit is used to quickly locate the worker's position and send a safety warning to the primary mining area management terminal when there is a risk of a production accident during the worker's production operations in the target mining area.

[0145] The beneficial effects of the above embodiments are as follows: The present invention classifies safety early warning sending targets according to whether an accident has occurred (including first-class accidents, second-class accidents, and third-class accidents) and has not occurred. Different safety accidents notify different mine management terminals, which notifies different mine management terminals to complete accident monitoring and prevent accident concealment, while improving the enterprise's production accident monitoring capabilities.

[0146] Example 10:

[0147] A satellite positioning-based method for monitoring workplace accidents, such as Figure 5 As shown, it includes:

[0148] Step 1: Monitor the mining area within the monitoring region using satellite data to obtain monitoring data;

[0149] Step 2: Process the monitoring data to determine whether a production accident has occurred in the target mining area or whether there is a risk of a production accident.

[0150] Step 3: When a production accident occurs or there is a risk of a production accident in the target mining area, the location of the target mining area is quickly determined based on satellite positioning, and a safety warning is sent to the mining area management terminal, which includes a primary mining area management terminal and a secondary mining area management terminal.

[0151] The beneficial effects of the above embodiments are as follows: This invention uses satellites to monitor mining areas and obtain monitoring data. After processing the monitoring data, it determines whether a production accident has occurred in the target mining area or whether there is a risk of a production accident. When a production accident occurs in the target mining area or there is a risk of a production accident, the system quickly determines the location of the target mining area based on satellite positioning and sends a safety warning to the mining area management terminal. This improves the real-time performance and comprehensiveness of mining area monitoring, eliminates the possibility of concealing mining accidents, and ensures the timeliness of accident detection. Furthermore, since the system is connected to both the enterprise's own management system and the government's management system, it can simultaneously investigate the risk of production accidents caused by workers' production operations while investigating mining accidents, thereby reducing the enterprise's accident rate.
