However, in the operation and maintenance management of coal mine network systems, the industry faces many challenges. The large number of underground network equipment and primitive access methods increase the complexity and difficulty of operation and maintenance.

In addition, problems such as inaccurate fault location, insufficient visualization, and lack of professional talents have also seriously restricted the development and application of coal mine network system operation and maintenance management platform.

[0003] In response to the above problems, some information technology companies have conducted relevant research and development, and proposed solutions such as topology visualization technology, active monitoring and alarm technology, and unified operation and maintenance platform technology.

[0069] S201: Connecting the basic information collected by the coal mine equipment data collector to the operation and maintenance management system.

[0070] The basic information is used to indicate the basic information of network equipment, sensors, industrial televisions, electronic fences and UPS underground and above the well.

[0071] The following is a specific implementation method for step S201 "connecting the basic information collected by the coal mine equipment data collector to the operation and maintenance management system".

[0072] In this embodiment, the coal mine equipment data collector is deployed at various key locations in the coal mine to collect real-time basic information such as network equipment, sensors, industrial televisions, electronic fences, and uninterruptible power supplies (UPS) underground and above the mine. This information includes but is not limited to the model, serial number, installation location, working status, performance parameters, etc. of the equipment.

[0073] The implementation details are as follows:

[0074] Data collector configuration: The data collector needs to be configured first to ensure that it can correctly collect the required basic information. This includes setting the collection frequency, data type, data format, etc.

[0075] After the configuration is completed, the data collector begins to collect basic information of coal mine equipment in real time.

[0076] Data transmission: The collected basic information is transmitted to the data access module of the operation and maintenance management system via wired or wireless methods. Wired methods may include Ethernet, optical fiber, etc., and wireless methods may include Wi-Fi, 4G / 5G and other communication technologies.

[0077] In order to ensure the accuracy and integrity of data, data compression, encryption and other technologies may be used during the transmission process.

[0078] Data access module processing: After receiving the basic information, the data access module first performs data analysis and format conversion to ensure that the data is compatible with other modules of the operation and maintenance management system.

[0079] The parsed data is stored in the system database for subsequent module calls and analysis.

[0080] Data verification and validation: During the data access process, data verification and validation may also be performed to ensure the accuracy and reliability of the data. This may include data integrity verification, data range verification, etc.

[0081] If data anomalies or errors are found, the system will issue an alarm or prompt so that the operation and maintenance personnel can handle it in time.

[0082] Basic information display: Although step S201 mainly focuses on the data access process, the basic information after access will be used by subsequent network topology visualization modules, device status monitoring modules, etc.

[0083] In particular, the network topology visualization module will use this information to construct the three-dimensional network topology structure of coal mine equipment, providing an intuitive visual display for operation and maintenance personnel.

[0084] Technical details and algorithms:

[0085] During data transmission, existing data compression algorithms (such as Huffman coding, LZW algorithm, etc.) are used to reduce the amount of data and improve transmission efficiency.

[0086] Data encryption technology (such as AES, RSA, etc.) is used to protect the security of data transmission.

[0087] Data checksum verification uses CRC (cyclic redundancy check) or hash algorithms such as MD5 to ensure data integrity.

[0088] In summary, step S201 of the embodiment of the present invention realizes the process of connecting the basic information collected by the coal mine equipment data collector to the operation and maintenance management system through the steps of configuring the data collector, transmitting basic information, data access module processing, data verification and validation, etc. These basic information provide important data support for subsequent network topology visualization, equipment status monitoring and flow monitoring.

[0089] S202: Receive the basic information, and use 3DMineGIS technology and digital twin technology to visualize the network topology structure of the coal mine equipment in three-dimensional form.

[0090] The following is a specific implementation method for step S202 "receiving the basic information, and using 3DMineGIS technology and digital twin technology to visualize the network topology structure of the coal mine equipment in three-dimensional form."

[0091] Receiving basic information: The operation and maintenance management system first receives basic information from the coal mine equipment data collector. This information includes detailed parameters and location information of underground and above-ground network equipment, sensors, industrial televisions, electronic fences and UPS.

[0092] The system performs preliminary processing on this information to ensure the accuracy and completeness of the data.

[0093] Utilize 3DMineGIS technology to construct 3D model: 3DMineGIS technology is a 3D modeling and visualization technology specially used for Geographic Information System (GIS). In this embodiment, this technology is used to construct a 3D model of coal mine equipment network.

[0094] The system creates a corresponding equipment model in three-dimensional space based on parameters such as equipment position, size, and shape in the basic information.

[0095] By adjusting the transparency, color and other properties of the model, the connection relationship and spatial layout between devices can be clearly displayed.

[0096] Application of digital twin technology: Digital twin technology is a technology that simulates the operating status and performance of a physical entity by building a virtual copy of it. In this embodiment, this technology is used to enhance the realism and interactivity of the 3D model.

[0097] The system associates the real-time operating status of each device (such as online / offline, performance parameters, etc.) with the corresponding device in the 3D model.

[0098] When the operating status of the equipment changes, the corresponding equipment in the 3D model will also update its display status in real time, thereby realizing real-time monitoring and visual display of the equipment status.

[0099] 3D visualization display: The system uses professional 3D visualization engines (such as Unity, Unreal Engine, etc.) to render and display 3D models.

[0100] Users can interact with the 3D model through devices such as mouse, keyboard or touch screen, such as rotation, zooming, translation and other operations, to gain a more comprehensive understanding of the network topology of coal mine equipment.

[0101] In addition, the system can also provide multiple view modes (such as top view, side view, perspective view, etc.) to meet the needs and preferences of different users.

[0102] Optimization and verification: In the process of building and displaying 3D models, the system may encounter performance bottlenecks or visual problems. Therefore, the model needs to be optimized and adjusted to ensure its smoothness and accuracy.

[0103] This may include reducing the complexity of the model, optimizing the rendering algorithm, adjusting lighting and shadow effects, etc.

[0104] At the same time, the system also needs to be verified and tested to ensure that the 3D model can accurately reflect the network topology and operating status of coal mine equipment.

[0105] Technical details and algorithms:

[0106] When constructing a three-dimensional model, the system uses data structures such as polygonal meshes (Mesh) or voxels (Voxel) to represent the shape and volume of the device.

[0107] When rendering a three-dimensional model, the system uses algorithms such as ray tracing or global illumination to simulate the propagation and reflection effects of light.

[0108] In order to achieve real-time update and interactive functions, the system uses event-driven or data binding technologies to synchronize the real-time status of the device with the display status in the 3D model.

[0109] In summary, step S202 of the embodiment of the present invention realizes an intuitive and visual display of the network topology of coal mine equipment by receiving basic information, using 3DMineGIS technology and digital twin technology to build and display a three-dimensional model. This provides users with a more comprehensive and in-depth means of understanding the equipment status and operating status, which helps to improve the efficiency and accuracy of operation and maintenance management.

[0110] Optionally, after receiving the basic information and using 3DMineGIS technology and digital twin technology to visualize the network topology structure of the coal mine equipment in three-dimensional form, it also includes: viewing the network layout and topology structure of the coal mine equipment in three-dimensional space through a three-dimensional space path planning unit, and planning the transmission path of the basic information.

[0111] After completing the steps of receiving basic information and visually displaying the network topology of coal mine equipment in three-dimensional form using 3DMineGIS technology and digital twin technology, the embodiment of the present invention also includes an optional subsequent step, namely, viewing the network layout and topology of coal mine equipment in three-dimensional space through a three-dimensional space path planning unit, and planning the transmission path of basic information.

[0112] The following are the specific implementation details of this step:

[0113] 1. 3D space viewing and analysis

[0114] Tools used: The system integrates 3D space viewing tools, such as the built-in navigation function of Unity or Unreal Engine, allowing users to freely move and rotate the perspective in a 3D environment through a mouse, keyboard or virtual reality device (such as a VR helmet) to comprehensively view the network layout and topology of coal mine equipment.

[0115] Interactive operation: Users can observe the specific location, connection method and surrounding physical environment of each device in detail by clicking, dragging and zooming. The system provides labeling and annotation functions to help users quickly identify and understand the function and status of the device.

[0116] 2. Path planning unit integration

[0117] Algorithm selection: For path planning, the system integrates the A (A-star) algorithm, which is a widely used heuristic search algorithm, especially suitable for finding the shortest path in a graph. The A algorithm combines the efficiency of the Dijkstra algorithm with the goal-oriented nature of breadth-first search, and can quickly find the optimal path in a complex three-dimensional environment.

[0118] Path planning process:

[0119] Input data: The path planning unit receives data from the 3D model, including the location coordinates of the device, connection relationships, and any obstacle information that may affect path planning.

[0120] Build a graph structure: Abstract the device network in three-dimensional space into a graph structure, where nodes represent devices and edges represent connections or possible transmission channels between devices.

[0121] Apply the A* algorithm: Run the A* algorithm on the constructed graph structure to find the shortest path from the source device to the target device. The algorithm takes into account the length of the path, obstacles, and possible priority factors (such as the reliability or bandwidth requirements of the path). Among them, the A* algorithm is a heuristic search algorithm, which was first proposed in the paper "A Formal Basis for the Heuristic Determination of Minimum Cost Paths" in 1964 in IEEE Transactions on Systems Science and Cybernetics. It combines the advantages of the greedy algorithm (depth first) and the Dijkstra algorithm (breadth first), and is a most effective direct search method for solving the shortest path in a static road network.

[0122] Output path: The algorithm outputs the optimal path, which is represented by three-dimensional coordinate points and can be directly visualized in the three-dimensional model.

[0123] 3. Path verification and optimization

[0124] Path verification: The system verifies the planned path to ensure that the path is feasible in the actual environment, does not encounter insurmountable obstacles, and meets the transmission performance requirements.

[0139] For example, when a device is online, its corresponding icon or color may be displayed as green; when a device fails or has performance abnormalities, it may be displayed as red or yellow with corresponding alarm information.

[0140] Performance parameter display: In addition to the online status of the device, the network topology visualization module can also display the performance parameter information of the device.

[0141] This can be achieved by embedding data labels, charts or dashboards in the 3D model so that operation and maintenance personnel can intuitively understand the performance status of the equipment.

[0142] Performance parameter information may include the real-time operating voltage, current, temperature, etc. of the equipment, as well as the historical change trends and threshold alarm information of these parameters.

[0143] Alarm and Notification: The real-time monitoring module is also responsible for detecting equipment failures or performance anomalies, and triggering alarm notifications in a timely manner when problems are detected.

[0144] Alarm notifications can be sent to operation and maintenance personnel through the system interface, SMS, email or sound, so that they can respond and handle the fault in a timely manner.

[0145] At the same time, alarm information, fault information and related operating status data will also be recorded in the operation and maintenance management system for subsequent query and analysis by operation and maintenance personnel.

[0146] Technical details and algorithms:

[0147] In the real-time monitoring module, the data stream processing algorithms used include Apache Flink, Apache Storm, etc. These algorithms can efficiently process real-time data streams and extract useful information.

[0148] The event-driven model is a programming model based on event triggering and response. It allows the system to perform corresponding operations according to the occurrence of events, thereby realizing real-time monitoring of device status.

[0149] In terms of performance parameter display, data visualization technologies that may be used include ECharts, D3.js, etc. These technologies can generate various types of data charts and dashboards to intuitively display the performance parameter information of the device.

[0178] Performance evaluation: Use specific performance evaluation algorithms (such as network throughput evaluation algorithm, delay evaluation algorithm, etc.) to conduct in-depth analysis of the received traffic data to evaluate the network performance of coal mine equipment. These algorithms can calculate key performance indicators such as network throughput, delay, jitter, etc. based on traffic data.

[0179] Anomaly detection: By comparing real-time traffic data with historical traffic data, anomaly detection algorithms (such as statistical anomaly detection algorithms, machine learning-based anomaly detection algorithms, etc.) are used to identify abnormal changes in traffic data, such as sudden traffic surges, sustained low traffic conditions, or significant changes in traffic patterns.

[0180] 2. Network configuration adjustment suggestions

[0187] Effect prediction: Use simulation tools or simulation algorithms (such as network simulation software OPNET, MATLAB, etc.) to simulate and test the optimized traffic control strategy to predict its effect in the actual network environment, including improvement in network throughput, reduction in latency, reduction in jitter, etc.

[0195] The fault detection module monitors the operating status data of coal mine equipment (such as operating voltage, current, temperature, vibration, etc.) in real time and compares it with the preset fault threshold. When the data exceeds the threshold, it is judged as an equipment failure.

[0196] The flow anomaly detection module monitors the flow data of coal mine equipment in real time (such as real-time flow size, flow rate, etc.), and compares and analyzes it with the preset flow threshold or historical flow data. When the data shows significant deviation or abnormal fluctuation, it is judged as flow anomaly.

[0197] Alarm notification triggering: Once the fault detection module or traffic anomaly detection module detects a problem, the system will immediately trigger an alarm notification.

[0198] Alarm notifications can be sent in a variety of ways, including but not limited to popping up an alarm window on the system interface, sending text messages or emails to the operation and maintenance personnel's mobile phones or mailboxes, and emitting sound or light signals, etc., to ensure that the operation and maintenance personnel can receive the alarm information in a timely manner.

[0200] The alarm record module will record in detail the alarm time, alarm type (fault or flow abnormality), alarm device, alarm reason (such as specific fault type, flow abnormality description, etc.) and alarm status (such as processed, pending, etc.).

[0201] Fault and flow abnormality data recording: In addition to alarm information, the operation and maintenance management system will also record detailed data related to faults or flow abnormalities.

[0202] This includes the operating status data of faulty equipment, flow data of equipment with abnormal flow, and related log information.

[0203] These data will be stored in the database of the operation and maintenance management system for subsequent query and analysis by operation and maintenance personnel.

[0204] Subsequent query and analysis: Operation and maintenance personnel can quickly retrieve relevant alarm information and fault / flow anomaly data through the query interface of the operation and maintenance management system based on conditions such as alarm time, equipment type, and alarm type.

[0206] Technical details:

[0207] In the process of fault and traffic anomaly detection, the system will use some existing algorithms or models to improve the accuracy and efficiency of detection. For example, for fault detection, the system may use machine learning algorithms (such as support vector machines, random forests, etc.) to train the equipment operation status data to establish a fault prediction model; for traffic anomaly detection, the system may use statistical methods (such as Z-score, IQR, etc.) or machine learning algorithms (such as isolation forests, clustering algorithms, etc.) to detect anomalies in traffic data.

[0208] The trigger mechanism of alarm notification will be customized according to the actual needs of the system and the preferences of the operation and maintenance personnel. For example, for different types of alarms (such as serious faults, minor faults, traffic anomalies, etc.), the system may set different alarm levels and notification methods to ensure that the operation and maintenance personnel can respond promptly according to the actual situation.

[0209] In summary, step S205 of the embodiment of the present invention realizes timely discovery, rapid response and effective management of faults and abnormalities in the operation and maintenance of coal mine equipment network through the detection of faults and abnormal flow, the triggering of alarm notifications, and the recording and analysis of alarm information and fault / abnormal flow data.
