[0021] It should be understood that the description in this section is not intended to identify key or essential features of the embodiments of this disclosure, nor is it intended to limit the scope of this disclosure. Other features of this disclosure will become readily apparent from the following description. Attached Figure Description

[0022] The accompanying drawings are provided to better understand this solution and do not constitute a limitation of this disclosure. Wherein: Figure 1 A flowchart illustrating a multi-service scheduling method for coal mines provided in this embodiment of the present disclosure; Figure 2 This is a schematic diagram of the structure of a coal mine multi-service scheduling device provided in an embodiment of the present disclosure; Figure 3 A schematic block diagram of an example electronic device provided for embodiments of this disclosure. Detailed Implementation

[0023] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0024] The following description, with reference to the accompanying drawings, outlines a coal mine multi-service scheduling method and apparatus, electronic device, and storage medium according to embodiments of this disclosure.

[0025] Figure 1 This is a flowchart illustrating a coal mine multi-service scheduling method provided in an embodiment of this disclosure.

[0026] like Figure 1 As shown, the method includes the following steps: Step 101: Construct a digital twin of the mine, access and integrate multi-source heterogeneous data in real time, and form a fused data model with spatial and logical connections.

[0027] In the embodiments of this disclosure, step 101 aims to construct a digital twin of the mine, which serves as the core carrier for mine data integration and modeling. By adapting to diverse data access methods, it acquires multi-source heterogeneous data from the mine scenario in real time and performs systematic fusion processing on this data. During the fusion process, the focus is on establishing spatial relationships (such as correspondence with actual underground locations in the mine) and logical relationships (such as causal or synergistic relationships between different types of data), ultimately forming a fused data model that comprehensively and accurately reflects the overall operating status of the mine. As one implementation method, it can access equipment sensor data, including equipment operating status parameters and environmental safety monitoring data, in real time through a standard industrial interface. Simultaneously, it can access video intelligent analysis data covering abnormal personnel behavior identification and environmental safety hazard identification through a message middleware protocol, thereby achieving effective access and fusion of multi-source heterogeneous data.

[0028] This step effectively solves the problem of data silos in existing technologies by constructing a digital twin of the mine and integrating multi-source heterogeneous data to form a correlated fused data model. It enables the dispersed data to have spatial and logical correlation, providing a unified and reliable data foundation for subsequent mine business perception, resource allocation and event response, and improving the data's ability to support mine scheduling decisions.

[0029] Step 102: Based on the service awareness mechanism, dynamically allocate 5G network slice resources to adapt to the communication needs of different services.

[0030] In the embodiments of this disclosure, step 102 establishes a service awareness mechanism to identify the differentiated communication requirements (such as latency, bandwidth, reliability, and other key performance indicators) of various mine services in real time, and dynamically allocates 5G network slice resources based on the identification results. The service awareness mechanism enables accurate judgment of the communication requirements of different service types, while the dynamic allocation of 5G network slice resources ensures that each type of service receives network resource support that matches its needs by adjusting resource configuration parameters within the slice (such as resource occupancy ratio, transmission priority, redundancy, etc.), thereby meeting the communication performance requirements of different mine services. As one implementation method, when a control-type service requiring low latency and high reliability is identified, a network slice with wireless resource reservation and transmission path redundancy can be automatically created; when a media stream service requiring high uplink bandwidth is identified, the uplink bandwidth allocation of the network slice can be dynamically adjusted and a priority scheduling mechanism can be enabled to match the differentiated communication requirements of the two types of services.

[0031] This step, by combining service awareness with dynamic allocation of 5G network slicing resources, effectively solves the problem of performance degradation of critical services caused by the inability of traditional networks to adapt to differentiated service requirements in existing technologies. It can ensure the communication quality of critical services such as low latency and high reliability, and achieve efficient use of network resources, avoiding resource waste, and providing reliable communication guarantee for the stable operation of various mine services.

[0032] Step 103: Control the heterogeneous terminals to perform routing selection and scheduling through a unified identity management mechanism.

[0033] In the embodiments of this disclosure, step 103 establishes a unified identity management mechanism to centrally manage the identity and status of various heterogeneous terminals (such as terminals with different communication standards and functional types) in the mining scenario, constructing a correlation system between terminal identity information, operating status, and scheduling requirements. Based on this unified management mechanism, combined with the actual scheduling task requirements and the real-time operating status of heterogeneous terminals, the routing selection logic and scheduling execution process of the terminals are uniformly controlled to ensure that scheduling instructions can match the optimal transmission path according to terminal characteristics and network conditions, while realizing standardized management of heterogeneous terminal scheduling behavior. As one implementation method, a real-time mapping relationship between unified identity identifiers and the status of various communication terminals can be maintained. Then, based on the content of scheduling instructions and the real-time status information of terminals, the optimal communication path, such as high-definition video communication, narrowband intercom communication, or IP broadcast communication, can be automatically selected to ensure the effective transmission of scheduling instructions.

[0034] This step controls the routing and scheduling of heterogeneous terminals through a unified identity management mechanism, effectively solving the problems of increased operation and maintenance costs, communication fragmentation, and reliance on manual judgment for routing selection caused by the need for heterogeneous terminals to maintain user databases independently in the existing technology. It reduces the complexity of terminal management and operation and maintenance costs, while improving the accuracy and efficiency of scheduling command transmission, and provides terminal-level protection for the smooth operation of multi-service scheduling in the mine.

[0035] Step 104: When the digital twin detects that a preset event has been triggered, it performs a multi-service collaborative operation.

[0036] In the embodiments of this disclosure, step 104 uses the mine digital twin as the core of event detection. Various events (such as safety hazard events, equipment malfunction events, etc.) that need to be triggered during mine operation are pre-defined. The digital twin monitors and analyzes real-time data in the fused data model. When data characteristics are identified as matching the triggering conditions of a preset event, multi-service collaborative operation is automatically initiated. This collaborative operation is not an independent response of a single business link, but rather integrates the operations of multiple business modules related to event handling (such as monitoring, communication, control, etc.), achieving synchronous and coordinated execution of each business link to ensure comprehensive and efficient event handling. As one implementation method, when a preset event is detected, a three-dimensional spatial visualization alarm can be displayed in the digital twin. Simultaneously, video surveillance resources related to the event are retrieved, and voice or text emergency commands are sent to terminals within the target area via cross-standard communication channels to complete the multi-service collaborative response.

[0037] This step effectively solves the problems of excessive scheduling time caused by relying on manual system switching for event response, process fragmentation, and reliance on human experience in existing technologies by using the preset event detection of digital twins and multi-business collaborative linkage. It realizes the automation and collaboration of event response, greatly shortens the event handling cycle, improves the response efficiency and handling reliability of mines in dealing with various events, and further supports the mine's "less manned and unmanned" safe operation needs.

[0038] The coal mine multi-service scheduling method disclosed herein constructs a mine digital twin to access and integrate multi-source heterogeneous data in real time, forming a fused data model with spatial and logical connections. Simultaneously, it dynamically allocates 5G network slice resources based on a service awareness mechanism to adapt to the communication needs of different services. Furthermore, it controls heterogeneous terminals to perform routing and scheduling through a unified identity management mechanism, and executes multi-service collaborative operations when the digital twin detects a preset event trigger. Therefore, it can solve the problems in existing technologies such as data silos caused by the lack of effective integration of multi-source heterogeneous data, performance degradation of critical services due to the inability to dynamically allocate 5G network resources according to service needs, increased operation and maintenance costs and communication fragmentation caused by the lack of unified identity management for heterogeneous terminals, and delayed scheduling response and reliance on manual experience due to the lack of an event-driven multi-service collaborative linkage mechanism. This achieves deep multi-source data collaboration, ensures accurate matching of different service communication needs, reduces the operation and maintenance costs of heterogeneous terminals and improves communication efficiency, and enables automated multi-service collaborative scheduling triggered by events, thereby supporting the technical effects of "less manned and unmanned" safe and efficient operation of mines.

[0039] As a specific implementation of this disclosure, based on the basic scheme, the construction of the mine digital twin is further defined to access and integrate multi-source heterogeneous data in real time, including: accessing equipment sensor data in real time through a standard industrial interface, wherein the equipment sensor data includes equipment operating status parameters and environmental safety monitoring data; and accessing video intelligent analysis data through a message middleware protocol, wherein the video intelligent analysis data includes personnel behavior anomaly identification and environmental safety hazard identification.

[0040] Specifically, in constructing a mine digital twin to achieve real-time access and fusion of multi-source heterogeneous data, differentiated access methods are adopted for the data access stage: For equipment sensor data, stable connections are established with various sensors in the mine through standard industrial interfaces such as RS485 and Profinet, collecting real-time equipment operating status parameters and environmental safety monitoring data output by the sensors. The equipment operating status parameters specifically include parameters reflecting the operating conditions of the equipment, such as the speed of the coal mining machine motor, the oil pressure of the scraper conveyor, and the working resistance of the hydraulic support. The environmental safety monitoring data specifically covers monitoring data directly related to safe production, such as underground gas concentration, carbon monoxide content, roadway temperature, and relative humidity. For video... The intelligent analysis data interacts with the underground video analysis system through message middleware protocols such as MQTT and Kafka. It receives the results data processed by video analysis algorithms. This intelligent video analysis data specifically includes the results of abnormal personnel behavior identification (such as personnel not wearing protective equipment as required, entering prohibited mining areas, operating equipment in violation of regulations, etc.) and the results of environmental safety hazard identification (such as cracks in the roadway roof, water and oil leaks in pipelines, deformation of support structures, etc.). The above two types of data are integrated into the database of the mine digital twin according to the mine spatial coordinates and logical association rules (such as the correspondence between sensor data in a certain area and video data in that area), providing specific and real-time data source support for the construction of the fused data model.

[0041] By clearly defining the specific applications of standard industrial interfaces and message middleware protocols, the stability and compatibility of accessing equipment sensor data and video intelligent analysis data are ensured. This approach leverages standard industrial interfaces to adapt to most existing sensor hardware in mines, reducing retrofit costs, while the message middleware protocol meets the high-concurrency, high-capacity transmission requirements of video intelligent analysis data. Furthermore, clarifying the specific content of the data makes the accessed data more targeted, effectively improving the accuracy and practicality of the mine's digital twin fusion data model, and providing a high-quality data foundation for subsequent model-based event detection and business scheduling.

[0042] As a specific implementation of this disclosure, based on the basic scheme, the dynamic allocation of 5G network slice resources based on the service awareness mechanism is further defined as follows: when a control service requiring low latency and high reliability is identified, a network slice with wireless resource reservation and transmission path redundancy is automatically created; when a media stream service requiring high uplink bandwidth is identified, the uplink bandwidth allocation of the network slice is dynamically adjusted and a priority scheduling mechanism is enabled.

[0043] Specifically, when dynamically allocating 5G network slice resources based on the service awareness mechanism, the service identification module first performs real-time detection and attribute determination of various services in the mine scheduling process to clarify the core communication requirement indicators of the services. When identifying control-type services requiring low latency and high reliability, such as control commands for unmanned driving equipment and remote control commands for hydraulic supports, the 5G network slicing management system automatically triggers a dedicated slice creation process. It allocates independent network slice resources for these services and configures a wireless resource reservation strategy—pre-allocating dedicated time slots, frequency resources, and channel capacity to avoid resource contention with other services. A redundant architecture with primary and backup dual transmission paths is constructed; if the primary path experiences a link interruption or latency exceeds a threshold, it immediately switches to the backup path to ensure the continuity and reliability of data transmission. When identifying media streaming services requiring high uplink bandwidth, such as underground emergency video transmission and multi-area real-time monitoring image uploads, the slicing management system monitors the current network resource occupancy in real time. Based on the bitrate requirements of the media streaming service (e.g., the bandwidth required for 4K video transmission), it dynamically adjusts the uplink bandwidth quota of the slice to which the service belongs. It expands channel bandwidth to meet the demands of high-capacity data transmission and simultaneously enables a slice priority scheduling mechanism, setting the scheduling priority of the media streaming service slice higher than that of ordinary data transmission services. This ensures that there are no stutters or packet loss during uplink data transmission, guaranteeing the real-time performance and integrity of the media streaming data.

[0044] By configuring differentiated slices for control and media streaming services, the communication requirements of the two core services are precisely matched: wireless resource reservation and transmission path redundancy design keep the latency of control services within a preset low threshold and significantly improve transmission reliability; dynamic adjustment of uplink bandwidth and priority scheduling mechanism fully meet the high bandwidth requirements of media streaming services and avoid transmission failures caused by insufficient bandwidth; at the same time, it realizes on-demand allocation of 5G network resources, avoids resource idleness or over-occupation, and improves network resource utilization.

[0045] As a specific implementation of this disclosure, based on the basic solution, the method of controlling heterogeneous terminals to perform routing selection and scheduling through a unified identity management mechanism is further defined as follows: maintaining a real-time mapping relationship between a unified identity identifier and the status of multiple communication terminals; automatically selecting the best communication path according to the content of the scheduling instruction and the real-time status information of the terminal, wherein the communication path includes high-definition video communication, narrowband intercom communication or IP broadcast communication.

[0046] Specifically, when controlling heterogeneous terminals to perform routing and scheduling through a unified identity management mechanism, a unique unified identity identifier is first assigned to all heterogeneous communication terminals in the mine (including 5G / 4G terminals, PDT / DMR walkie-talkies, Wi-Fi terminals, etc.). An association file is established between the identity identifier and the basic information of the terminal (model, supported communication standards, bound personnel / equipment number), and a real-time mapping management module is built. The real-time status information of the terminal (including online status, signal strength, remaining battery power, current location, supported communication bandwidth, etc.) is dynamically obtained through the heartbeat packets periodically sent by the terminal. The mapping relationship between the unified identity identifier and the terminal status is continuously updated to ensure the real-time performance and accuracy of the mapping data. When a dispatch command needs to be issued, the dispatch system first parses the command content to clarify the communication requirements (such as whether visual interaction is required, whether it is an emergency instant communication, or whether it needs to be notified to multiple terminal groups). Then, it retrieves the real-time status information of the terminals in the unified identity management module and performs path matching based on the two: if the command needs to visually present the situation on site (such as confirming the scene of the event), and the terminal signal strength is sufficient and supports high-definition video transmission, then the high-definition video communication path is selected; if the command is an emergency voice dispatch, the terminal signal is weak, or it only supports narrowband communication, then the narrowband intercom communication path is selected to ensure that the command is delivered quickly; if the command is a notification to all personnel (such as an evacuation command or a security warning), then the IP broadcast communication path is selected to enable simultaneous reception by multiple terminals, thereby completing the automatic routing selection and dispatch execution of heterogeneous terminals.

[0047] By mapping unique identifiers to terminal status in real time, precise control of heterogeneous terminals is achieved, avoiding information disconnect caused by independent database maintenance. Combining instruction requirements with terminal status, three types of communication paths are automatically selected, which not only covers the scheduling needs in different scenarios, but also avoids the tedious operation of manually judging terminal type and path, greatly improving the accuracy and efficiency of scheduling instruction transmission, while reducing the risk of instruction loss or delay due to improper path selection, and further optimizing the scheduling and coordination effect of heterogeneous terminals.

[0048] As a specific implementation of this disclosure, based on the basic scheme, the automatic selection of the best communication path is further defined as follows: when the terminal battery is detected to be low or the signal strength is lower than a preset threshold, the automatic switch to the degraded communication route based on regional positioning is made; when group communication is initiated, multiple communication instructions are generated in parallel and uniform scheduling content is sent to different types of terminals respectively.

[0049] Specifically, during the automatic selection of the optimal communication path, a special adaptation mechanism is designed for abnormal terminal states and group communication scenarios: the terminal feeds back power and signal strength data to the unified identity management module in real time. The system presets power thresholds (e.g., remaining power below 20%) and signal strength thresholds (e.g., reference signal received power below -110dBm). When the terminal's power is detected to be below the preset power threshold or its signal strength is detected to be below the preset signal strength threshold, it is determined that the terminal does not have the stable transmission conditions for high-definition video communication or complete narrowband intercom. At this time, a degraded communication route switching process is automatically triggered. Based on the area location information reported by the terminal in real time (e.g., the lane number and area coordinates), the system matches basic communication nodes (e.g., area repeaters, low-power base stations) with wider coverage and lower transmission power consumption in the area, constructs a degraded communication route, and transmits only simplified scheduling instructions (e.g., short text instructions, voice clips) to ensure that the core information of the instructions is not lost. When initiating group communication, the scheduling system first parses the terminal types included in the group (e.g., 5G terminals, PDT walkie-talkies, IP broadcast terminals, etc.) and then, according to the communication protocols supported by different terminals (e.g., 5G...). The system generates multiple communication commands in parallel using NR, PDT, and IP multicast protocols, with consistent command content (such as identical emergency evacuation notices and operational adjustment requirements). These commands are then sent synchronously to all different types of terminals within the group through their respective adapted communication channels, achieving full coverage scheduling of terminals within the group.

[0050] By employing a degraded communication routing mechanism, communication interruptions caused by insufficient battery power or weak signal at the terminal are effectively avoided, ensuring the transmission of core information of scheduling instructions under extreme conditions. The parallel generation and synchronous transmission of multiple instructions during group communication solves the problems of incompatible instruction formats and asynchronous transmission in heterogeneous terminal group scheduling, ensuring that all terminals in the group can receive unified scheduling content simultaneously, greatly improving the timeliness and consistency of group scheduling, and further optimizing the collaborative scheduling effect of heterogeneous terminals.

[0051] As a specific implementation of this disclosure, based on the basic solution, the execution of multi-service collaborative operation is further defined as follows: performing three-dimensional spatial visualization alarm display in the digital twin; retrieving video surveillance resources related to the event; and sending voice or text emergency commands to terminals in the target area through cross-standard communication channels.

[0052] Specifically, when performing multi-business collaborative operations, a series of coordinated actions are carried out based on the three-dimensional spatial model of the digital twin: In the three-dimensional spatial visualization alarm display stage, the digital twin, based on the spatial coordinate information of the event in the fused data model, accurately locates the location of the event in a three-dimensional model that is proportionally mapped to the actual underground roadways and equipment layout of the mine. The event range is marked by highlighted color blocks (such as flashing red areas), and event type labels (such as "gas exceedance" and "equipment malfunction") and key parameter values ​​(such as gas concentration values) are superimposed. At the same time, the icons of related equipment in the linkage model (such as nearby sensors and worker location markers) flash synchronously, intuitively presenting the scope of the event and related objects; In the video surveillance resource retrieval stage, the digital twin automatically searches the pre-stored monitoring equipment location database based on the event spatial coordinates and matches the event area. The system also includes high-definition cameras within a 50-meter radius. These cameras are controlled via interface commands to turn towards the core area of ​​the incident, and their video streams are retrieved in real time and displayed in a pop-up window next to the 3D model. It also supports reviewing historical recordings from the 5 minutes prior to the incident, providing dispatchers with dynamic on-site information. In the emergency command transmission phase, the system first filters all heterogeneous terminals within the target area (such as 5G terminals and walkie-talkies carried by workers, and broadcast terminals within the area) through a unified identity management mechanism. Based on the communication standards supported by the terminals, it activates cross-standard communication channels (such as integrating 5G communication modules, PDT walkie-talkie protocol interfaces, and IP broadcast gateways). Depending on the urgency of the incident, it automatically generates voice commands (such as "Gas level at tunnel face 3 exceeds the standard, evacuate immediately") or text commands (including evacuation route diagrams), which are then simultaneously sent to the target terminals through the corresponding channels, ensuring no commands are missed.

[0053] 3D visualization alarms make the location of events and related information more intuitive, making it easier for dispatchers to quickly grasp the situation; real-time retrieval of related video resources provides on-site evidence for decision-making and reduces information blind spots; cross-standard communication channels ensure full coverage of emergency commands to all terminals in the target area, avoiding command omissions due to differences in terminal types. The collaboration of these three elements significantly shortens the response cycle from event detection to command execution, improving the accuracy and efficiency of emergency response.

[0054] It should be noted that the embodiments of this disclosure may include multiple steps. For ease of description, these steps are numbered, but these numbers are not a limitation on the execution time slots or execution order between the steps; these steps can be implemented in any order, and the embodiments of this disclosure do not limit this.

[0055] Corresponding to the aforementioned multi-service scheduling method for coal mines, this disclosure also proposes a multi-service scheduling device for coal mines. Since the device embodiments of this disclosure correspond to the aforementioned method embodiments, details not disclosed in the device embodiments can be referred to the aforementioned method embodiments, and will not be repeated here.

[0056] Figure 2 This is a schematic diagram of the structure of a coal mine multi-service dispatching device provided in an embodiment of this disclosure, as shown below. Figure 2 As shown, it includes: Construction unit 21 is used to construct a digital twin of the mine, and to access and integrate multi-source heterogeneous data in real time to form a fused data model with spatial and logical relationships.

Control unit 23 is used to control heterogeneous terminals to perform routing selection and scheduling through a unified identity management mechanism; The execution unit 24 is used to perform multi-service collaborative operations when the digital twin detects that a preset event has been triggered.

[0057] The coal mine multi-service scheduling device disclosed herein constructs a mine digital twin to access and integrate multi-source heterogeneous data in real time, forming a fused data model with spatial and logical connections. Simultaneously, it dynamically allocates 5G network slice resources based on a service awareness mechanism to adapt to the communication needs of different services. Furthermore, it controls heterogeneous terminals to perform routing and scheduling through a unified identity management mechanism, and executes multi-service collaborative operations when the digital twin detects a preset event trigger. Therefore, it can solve the problems in existing technologies such as data silos caused by the lack of effective integration of multi-source heterogeneous data, performance degradation of critical services due to the inability to dynamically allocate 5G network resources according to service needs, increased operation and maintenance costs and communication fragmentation caused by the lack of unified identity management for heterogeneous terminals, and delayed scheduling response and reliance on manual experience due to the lack of an event-driven multi-service collaborative linkage mechanism. This achieves deep multi-source data collaboration, ensures accurate matching of different service communication needs, reduces the operation and maintenance costs of heterogeneous terminals and improves communication efficiency, and enables automated multi-service collaborative scheduling triggered by events, thereby supporting the technical effects of "less manned and unmanned" safe and efficient operation of mines.

The video intelligent analysis data includes the identification of abnormal human behavior and the identification of environmental safety hazards.
