Description

Technical Field

[0001] This invention relates to the fields of coal mine safety management and control, Internet of Things data acquisition, edge intelligent computing and emergency linkage control technology, specifically a lightweight emergency control system for full-domain monitoring of coal mines based on edge intelligent linkage and safety situation awareness. Background Technology

[0002] Coal mine safety monitoring and emergency control are core and crucial links in ensuring safe production underground. However, current coal mine safety management systems have revealed numerous technical deficiencies in practical applications and are no longer suitable for the safety management needs of modern coal mines. The main problems are as follows: 1. The data perception dimension is singular. Most existing safety monitoring systems only collect single environmental parameters and lack comprehensive perception of the operating status of electromechanical equipment, personnel positioning information, ventilation pressure data, and power supply status. This makes it impossible to form a comprehensive safety situation judgment in coal mines and easily leads to missed or false alarms of safety risks. 2. The emergency response latency is relatively high. Traditional emergency response solutions adopt a cloud-based centralized decision-making model, and all monitoring data must be uploaded to a remote server for analysis and processing. The network latency problem is significant. In emergency scenarios such as gas over-limit, sudden water level increase, and fire hazard, it is impossible to achieve millisecond-level emergency response, which can easily lead to further expansion of safety risks. 3. Insufficient communication fault tolerance. Weak networks, network outages, and electromagnetic interference occur frequently in underground coal mines. The existing system will immediately lose its safety control capabilities after communication is interrupted and will be unable to perform local emergency actions, resulting in serious safety management loopholes. 4. Poor system deployment adaptability: mainstream safety control systems have bloated architectures, high deployment costs, and stringent hardware configuration requirements, making it difficult for small and medium-sized coal mines to afford the transformation costs. Furthermore, the system linkage strategies are not customizable and have poor scalability, making it impossible to adapt to the safety management standards of different mines. 5. Lack of integrated technical solutions: Currently, there is no coal mine-specific safety control system that integrates multi-source data fusion across the entire domain, intelligent safety situation assessment, edge local emergency linkage, full-function survival during network outages, and lightweight rapid deployment. The lack of relevant integrated technical solutions has become a major bottleneck restricting the improvement of the inherent safety level of coal mines. Summary of the Invention

[0003] To address the technical challenges of existing coal mine safety monitoring systems, such as insufficient data fusion, delayed emergency response, strong dependence on cloud communication, network outage failure, complex deployment, and high transformation costs, this invention provides a lightweight emergency control system for coal mine full-domain monitoring based on edge intelligent linkage and safety situation awareness. This system enables full-domain acquisition of multi-source data in underground coal mines, intelligent safety situation assessment, edge local linkage decision-making, hierarchical emergency control, and offline autonomous operation. With its lightweight architecture, it comprehensively improves the emergency response capabilities and system reliability of coal mine safety, while reducing the cost of intelligent transformation of coal mine safety.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows: a lightweight emergency control system for full-domain monitoring of coal mines based on edge intelligent linkage and safety situation awareness, including a full-domain multi-source sensing unit, a safety situation fusion assessment unit, an edge intelligent linkage decision-making unit, a hierarchical emergency execution unit, an offline autonomous survival unit, and a cloud-based safety supervision unit.

[0005] The comprehensive multi-source sensing unit is used to simultaneously collect environmental data such as underground gas concentration, carbon monoxide concentration, dust concentration, temperature, water level, and wind pressure, as well as operational data such as the start / stop of electromechanical equipment, current, and voltage, and personnel-related data such as personnel positioning, area entry and exit, and equipment status, to construct a comprehensive safety monitoring dataset for coal mines.

[0006] The safety situation fusion assessment unit is used to perform normalization fusion, threshold verification, and trend prediction processing on multi-source monitoring data in sequence. Based on the superposition of multi-dimensional data, it automatically determines the downhole safety level and generates four levels of safety situation results: low risk, general risk, relatively high risk, and major risk. This unit adopts a multi-factor weighted judgment algorithm to avoid false triggering of safety warnings by single parameters and improve the accuracy and reliability of safety judgment.

[0007] The edge intelligent linkage decision-making unit is deployed on the mining edge gateway and has a locally loaded custom emergency strategy library. It can automatically match the corresponding linkage rules according to the security situation level output by the security situation fusion assessment unit. It can generate accurate emergency control commands without data interaction with the cloud, realizing the localized independent operation of coal mine emergency decision-making. At the same time, the unit supports visual editing of strategies. Coal mine managers can customize linkage actions corresponding to different risk levels according to the actual needs of the mine, adapting to the safety management requirements of different mines.

[0008] The hierarchical emergency execution unit is used to drive emergency equipment to complete linkage actions in a hierarchical manner according to the decision instructions generated by the edge intelligent linkage decision unit. Specifically, it includes integrated emergency execution operations such as audible and visual alarms, emergency broadcasts, fan start and stop, water pump start, area power outage, damper control, and power supply cut-off, so as to achieve precise hierarchical emergency response.

[0009] The offline autonomous keep-alive unit is used to automatically switch the control system to offline operation mode when wireless communication is interrupted in the coal mine. In the offline state, it retains all functions such as data acquisition, situation assessment, linkage control and log storage capabilities. After the network is restored, it automatically synchronizes the monitoring data and emergency event records from the offline stage to ensure the integrity and continuity of the data.

[0010] The cloud-based safety monitoring unit is used to remotely monitor the safety situation in coal mines in real time, receive emergency alarm information from the system, view emergency response operation records, remotely adjust emergency strategies at the edge, and generate coal mine safety statistical reports, thereby achieving traceable supervision of the entire coal mine safety management process.

[0011] Furthermore, the system of this invention adopts a lightweight edge computing architecture, in which all data processing, decision-making, and emergency control operations are completed locally in the coal mine, significantly reducing the requirements for network bandwidth and cloud server configuration, and enabling rapid deployment and low-cost operation and maintenance of the system.

[0012] Furthermore, the system of this invention has the function of operation log and full event recording. All monitoring data, emergency response actions and safety alarm information are stored with timestamps, which meets the normative requirements of coal mine safety supervision and the traceability requirements after an accident.

[0013] Beneficial effects Compared with existing coal mine safety monitoring and emergency control systems, this invention has the following significant advantages: 1. Achieving multi-source data fusion perception and comprehensive situation assessment: This invention collects multi-dimensional data from three categories—environment, equipment, and personnel—through a multi-source perception unit. The data is then comprehensively judged by a multi-factor weighted algorithm of the security situation fusion assessment unit. Compared with traditional single-parameter monitoring methods, this significantly improves the accuracy of security judgment and effectively reduces the false alarm and false negative rates of security risks. 2. Achieve millisecond-level local emergency response by adopting an edge intelligent independent decision-making mode. Emergency strategy matching and control command generation are completed locally at the mining edge gateway without cloud interaction, thus completely solving the core pain points of high network latency and delayed emergency response in traditional cloud control systems. 3. It has a highly reliable offline operation capability. The offline autonomous keep-alive unit ensures that the system can run locally with full functionality when communication is interrupted, eliminating the risk of safety loss of control due to communication failure and significantly improving the system's operational reliability and safety fault tolerance in coal mines. 4. The hierarchical emergency response is more precise. By classifying safety situations into four levels—low, general, relatively high, and critical—and corresponding hierarchical emergency execution mechanisms, precise emergency response can be achieved, avoiding blind start-up and shutdown of equipment. This ensures safe underground production while also maintaining the continuity of coal mine production. 5. The lightweight architecture is highly adaptable and has low transformation costs. The system adopts an edge lightweight computing architecture with low hardware configuration requirements and a simple deployment process. It does not require large-scale underground cabling and high-performance cloud servers, and can be adapted to the rapid safety and intelligent upgrade and transformation of large mines and small and medium-sized coal mines. 6. Meeting the needs of personalized management and full-process supervision, the system supports visual and customizable editing of emergency strategies, can be adapted to the safety management standards of different mines, and features full-process log recording with timestamps and traceable supervision in the cloud. It meets the dual needs of personalized safety management and industry supervision and auditing in coal mines, is highly practical, has high industry promotion value, and can comprehensively improve the inherent safety level of coal mines.

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the technical solutions of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0016] Example: This embodiment provides a lightweight emergency control system for comprehensive monitoring of coal mines based on edge intelligent linkage and security situation awareness, combined with... Figures 1-3 The system includes a multi-source perception unit 1, a security situation fusion assessment unit 2, an edge intelligent linkage decision-making unit 3, a hierarchical emergency execution unit 4, an offline autonomous survival unit 5, and a cloud-based security monitoring unit 6. The edge intelligent linkage decision-making unit 3 is deployed on the mining edge gateway 7 and has a custom emergency strategy library 8 loaded locally. The hierarchical emergency execution unit 4 is electrically connected to the underground emergency equipment group 9 to realize the execution of emergency commands.

[0017] Implementation of the operation of the global multi-source sensing unit 1: This unit uses various mining sensors, personnel positioning base stations, and equipment status acquisition modules deployed underground in the coal mine to simultaneously collect environmental data such as underground gas concentration, carbon monoxide concentration, dust concentration, temperature, water level, and wind pressure; operational data such as start / stop, current, and voltage of electromechanical equipment such as scraper conveyors, coal mining machines, and ventilation fans; and personnel-related data such as personnel positioning coordinates, underground area entry and exit records, and personnel movement trajectories. After standardizing and organizing all collected data, a coal mine-wide safety monitoring dataset is constructed, and the dataset is transmitted in real time to the safety situation fusion assessment unit 2.

[0018] Implementation of Security Situation Integration Assessment Unit 2: This unit receives the full-domain safety monitoring dataset transmitted by the full-domain multi-source sensing unit 1. First, it normalizes and fuses monitoring data of different types and ranges to unify data evaluation standards. Then, it performs threshold verification on the fused data to filter out abnormal data exceeding safety thresholds. Next, it analyzes the changing trends of abnormal data using a trend prediction algorithm to determine the development direction of risks. Finally, it uses a multi-factor weighted judgment algorithm, combined with the superposition of multi-dimensional data, to automatically determine the underground safety level, generating four levels of safety status results: low risk, general risk, relatively high risk, and major risk. This result is transmitted in real time to the edge intelligent linkage decision-making unit 3. For example, when the underground gas concentration slightly exceeds the threshold and there are no other abnormal data, it is judged as a general risk; when the gas concentration significantly exceeds the standard and is accompanied by the ventilation fan shutdown and personnel being in a dangerous area, it is judged as a major risk.

[0019] Implementation of the work of edge intelligent linkage decision-making unit 3: This unit is deployed on the mining edge gateway 7. It is pre-loaded locally with a custom emergency strategy library 8, which is visually edited by coal mine managers according to mine safety management regulations. When it receives the level 4 safety situation result from the safety situation fusion assessment unit 2, it quickly matches the emergency strategy locally without needing to interact with the cloud-based safety supervision unit 6. It directly generates precise emergency control instructions corresponding to the safety situation level and transmits the instructions to the hierarchical emergency execution unit 4. For example, when a major risk level is matched, a combined control instruction of "audible and visual alarm + emergency broadcast evacuation + area power outage + start backup ventilation fan + cut off power supply" is generated.

[0020] Implementation of the work of Tiered Emergency Execution Unit 4: After receiving the emergency control command from the edge intelligent linkage decision unit 3, the unit drives the downhole emergency equipment group 9 to perform corresponding hierarchical linkage actions according to the level and content of the command. The emergency equipment group 9 includes audible and visual alarms, emergency broadcasting equipment, ventilation fans, water pumps, power-off switches, air door control devices, etc., to achieve integrated emergency response. All linkage actions are recorded with timestamps and synchronized to the offline autonomous survival unit 5.

[0021] Implementation of offline autonomous keep-alive unit 5: When wireless communication is interrupted or electromagnetic interference occurs underground in the coal mine, and the connection between the system and the cloud-based safety monitoring unit 6 is lost, the offline autonomous keep-alive unit 5 immediately triggers the system's offline operation mode. In the offline state, it ensures the full-function operation of the multi-source perception unit 1, the safety situation fusion assessment unit 2, the edge intelligent linkage decision-making unit 3, and the hierarchical emergency execution unit 4. At the same time, it stores all monitoring data, situation assessment results, emergency linkage actions, and alarm information in the offline phase locally. When underground communication is restored and the system reconnects to the cloud-based safety monitoring unit 6, the unit automatically synchronizes all data and event records stored in the offline phase to the cloud, ensuring data integrity and the continuity of coal mine safety management.

[0022] Implementation of Cloud Security Monitoring Unit 6: This unit is deployed in a remote monitoring center on the surface of the coal mine. It can receive and display the safety status results and monitoring data transmitted from underground in real time. When the system determines that the risk level is not low, it will promptly receive emergency alarm information and trigger ground alarms. At the same time, it supports coal mine managers to remotely view the operation records of underground emergency linkage and offline synchronized event data. It can remotely adjust the custom emergency strategy library 8 of the edge intelligent linkage decision unit 3 through a visual interface, and automatically generate coal mine safety statistical reports based on underground full-cycle data, so as to realize traceable supervision of the entire coal mine safety management process.

[0023] Furthermore, the system of this invention adopts a lightweight edge computing architecture. All core operations, including data processing, decision-making, and emergency control, are completed on the local mining edge gateway 7 in the coal mine. This significantly reduces the requirements for network bandwidth and cloud server configuration. The system deployment can be completed simply by deploying mining sensors and edge gateways, without the need for large-scale underground cabling. The transformation cost is low, and it can be quickly adapted to the safety and intelligent upgrade of various coal mines. At the same time, all operations of the system are recorded with timestamps, which meets the industry standards for coal mine safety supervision and the traceability requirements after an accident.

[0024] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
