[0036] The interface module is used to ensure that the call response time of the system interface and the external interface is within 200ms. Data is transmitted through the mine industrial ring network and gigabit optical fiber to ensure millisecond-level data delay.

[0037] The mobile monitoring system based on the coal mining industry integrates multiple key modules in detail. Each module is designed for a specific function to ensure the efficient operation of the system and optimize the user experience. The following is a functional description of each module of the system:

[0038] The present invention also includes

[0039] Alarm processing unit: Receives and processes alarm signals from monitoring equipment to quickly respond to emergencies within the mine.

[0040] Permission management unit: manages user operating permissions to ensure that users can only perform authorized activities, thereby increasing system security.

[0041] The present invention also provides a data infrastructure layer, which is configured with:

[0042] WebSocket communication: supports real-time data communication and keeps data synchronized among components within the system.

[0043] Nacos Service Center: Maintains high availability and load balancing of internal services through service discovery and registration.

[0050] The present invention uses a real-time data processing module, and the system can monitor various equipment states and environmental parameters in the coal mine in real time, such as gas concentration, temperature, etc., respond to potential safety threats in a timely manner, and reduce the probability of accidents. The equipment control module allows operators to remotely control coal mine equipment, such as coal mining machines and conveyor belts, which reduces the number of times workers need to directly contact dangerous areas, thereby enhancing the safety of operations. The process of automatically creating and managing WebSocket connections and UUID identifications in the present invention reduces the need for manual intervention, making data transmission and equipment control more efficient. The system design ensures that the interface response time is within 200ms, which means that the delay from data transmission to equipment control is extremely low, and emergencies can be responded to quickly and adjusted in time. The system renders real-time video and data on the mobile terminal, combined with an intuitive operating interface, which greatly improves the user experience and convenience of operation. Since the system supports running on mobile terminals that have passed intrinsic safety and explosion-proof certification, operators can monitor and control equipment at any location in the mine area, no longer limited to fixed monitoring stations or control rooms. All sensitive HTTP communications are encrypted using the AES encryption algorithm to protect the security of control instructions and data transmission. The system uses a joint authentication mechanism of account, password and device MAC address to ensure that only authorized users can access the system, effectively preventing unauthorized access. The inter-service communication and address forwarding achieved by nginx and nacos improve the stability and scalability of the system. The present invention provides a comprehensive solution that aims to improve the safety, efficiency, convenience and reliability of coal mine operations through highly integrated technical modules.

[0051] In this embodiment, the data processing module is also used to push updates to the front-end service of the mobile terminal through a WebSocket connection when the data changes. The functions of the data processing module are not limited to basic data reception and transmission, but also include real-time push data updates to the mobile terminal using a WebSocket connection. This feature greatly enhances the responsiveness and flexibility of the system, so that in the dynamic environment of a coal mine, any critical data changes can be quickly captured and processed by the front-end service. For example, if a sudden increase in the concentration of hazardous gas is detected, the system will immediately send an alarm to the operator's mobile device through WebSocket to ensure sufficient response time to take action, thereby improving the safety and work efficiency of the miners.

[0052] In this embodiment, the equipment control module is also used to communicate with the centralized control system by using a RESTful API interface, thereby realizing remote monitoring and control of the comprehensive mining equipment. This design allows operators to operate the equipment from any location through a simple network request without physically approaching dangerous or difficult-to-reach areas. In addition, the use of RESTful API makes the system more modular, easy to maintain and expand, and also supports a variety of different types of client technologies, enhancing the versatility and future compatibility of the system.

[0053] In this embodiment, the video management module supports multi-channel video monitoring, allowing users to select specific video streams from multiple cameras for viewing. This function not only enhances the flexibility and comprehensiveness of monitoring, but also enables operators to more effectively monitor multiple key points throughout the mine. For example, operators can simultaneously observe the conditions of the import area and the coal face, discover and solve problems in a timely manner, and ensure production safety.

[0054] In this embodiment, the system stability and security module is also used to use the JSON format to exchange data between services to simplify data processing and improve the interoperability of the system. The system stability and security module uses the JSON format to exchange data between services, which not only simplifies the data processing process, but also improves the interoperability of the system. As a lightweight data exchange format, JSON is widely supported in various programming languages, which enables the system to be easily integrated with external systems, such as ERP systems or other monitoring tools, and also facilitates the addition of new functions and the upgrade of old systems.

[0055] In this embodiment, the communication and interface module is also used to support the adjustment of the data synchronization frequency through configuration to adapt to different network conditions and data requirements. The communication and interface module provides configurability of the data synchronization frequency, which allows the system to adjust according to different network conditions and data requirements. In the case of poor network conditions or low data requirements, the data synchronization frequency can be reduced to reduce the network load and the processing pressure of the server. Conversely, in critical operations or high data requirements, the synchronization frequency can be increased to ensure the real-time and accuracy of the data. This flexible adjustment mechanism provides the system with better adaptability and stability, enabling it to maintain efficient operation in various operating environments.

[0056] like Figure 2 As shown, the present invention also provides a mobile monitoring method based on the coal mining industry, comprising the following steps:

[0057] User login steps: The user provides login credentials, the system verifies the credentials, and determines whether the login is successful. If the login is successful, the user enters the system; if it fails, an error message is displayed and the user logs in again.

[0058] Create a WebSocket connection step: Create a WebSocket connection for each successfully logged-in user to achieve real-time data communication. Generate a unique UUID for each connection, and the user selects the operation to be performed in the system, which may include viewing data, controlling devices, etc.

[0059] Operation classification step: according to the operation type selected by the user, if the operation type is data viewing or processing, go to the data management process step; if the operation type is device control, go to the device control process step; if the operation type is video monitoring, go to the video management step;

[0060] Data management steps: The system receives data from external sensors through MQTT middleware, pushes data to the user interface through WebSocket connection, and realizes real-time data rendering.

[0061] Device control steps: Send an HTTP request to the centralized control system, call the corresponding device control interface, encrypt the HTTP request with AES to ensure the security of the instruction, and the system updates the user interface based on the device response result.

[0062] Video management steps: call the video surveillance system, obtain the video stream, adjust the video output according to user operations, and render the video stream to the user interface in real time.

[0063] For example, in the device control step, the system constructs an HTTP request. The HTTP request includes the control commands to be executed, such as starting or stopping the operation. The HTTP request is encrypted with AES to ensure the secure transmission of the control command. The encrypted request is sent to the centralized control system. The centralized control system decrypts and parses the HTTP request. According to the instructions in the request, the control operation is performed on the corresponding device. After the centralized control system performs the operation, the result is fed back to the mobile monitoring system. The feedback information is sent back to the user interface in real time through the WebSocket connection. After receiving the operation result, the user interface displays the corresponding status update, such as whether the device has been started or stopped.

[0064] When the login is successful or the page is switched, a new websocket connection is created and a unique uuid is generated. The abandoned websocket connection is deleted through the uuid of each websocket.

[0065] This system obtains real-time data by monitoring the mqtt middleware. The data source of mqtt is the original sensor data received and forwarded by the centralized control system (external system). This system encapsulates mqtt and websocket. The data monitored by mqtt will be pushed to the existing websocket terminal with the same identification code. The front-end service subscribes to the websocket to receive the data and renders it on the mobile terminal page.

[0066] According to the interface specification of the centralized control system (external system), this system sends an http request to call the centralized control system (external system) interface and sends the control command to the support, coal mining machine, scraper and other comprehensive mining equipment. The http request URL of the centralized control system (external system) is encrypted by the AES encryption algorithm.

[0067] This system uses RestTemplate to call the comprehensive mining face data analysis system (external system), and the data is returned to the front end to initialize the page rendering. At the same time, the page data is updated in real time through the websocket client in Article 2

[0068] This system calls the video monitoring system (external system) through the front-end service to obtain the video stream, and renders the real-time image of any configured monitoring camera on the comprehensive mining working face on the mobile terminal. The camera control interface can be called through http requests to perform operations such as zooming in, zooming out, and rotating the camera image.

[0069] The interface calls of external systems are forwarded through nginx, and the interface calls between different internal services are implemented through the nacos registration center to ensure system stability and achieve configuration isolation between services. Data exchange between services uses the json format.

[0070] The mobile terminal uses the Android 11 operating system, has 4G memory, and is an intrinsically safe and explosion-proof certified device, so it can be carried to the underground comprehensive mining face for use.

[0071] In terms of security and privacy protection, when a user logs in, there will be a joint verification of account, password, and device MAC address whitelist.

[0072] The call response time of this system interface and external interface is within 200ms. It relies on the mine industrial ring network and gigabit optical fiber for data transmission to ensure millisecond-level data delay.

[0073] Regarding the implementation plan, in the on-site deployment, the network problem should be solved first to ensure that the network using the mobile terminal is connected to the underground industrial ring network. Install the server, deploy this system, video monitoring system, centralized control system, etc. Before using the mobile terminal, the centralized control system adds a whitelist of users and devices for the mobile terminal to log in.

[0074] The system monitors various environmental and equipment parameters in the coal mine in real time, responds to potential dangers in a timely manner, and reduces the risk of accidents. In addition, the remote control function reduces the need for employees to be directly exposed to high-risk environments. Automated data processing and equipment control processes significantly improve the speed and accuracy of operational response. The system design ensures extremely low latency in data and command transmission, making decision-making and execution faster.

[0075] By rendering video and data in real time on mobile terminals and providing an intuitive user interface, the system greatly facilitates monitoring and management tasks for on-site and remote operators. Using advanced encryption technology and multiple authentication mechanisms, the system ensures the security of data transmission and the protection of sensitive information. Utilizing modern software architecture and middleware, the system provides a high degree of reliability and seamless collaboration between services, ensuring operational continuity. The modular design of the system allows for rapid functional expansion or modification based on future technological developments or specific needs.

[0076] In short, this mobile monitoring system based on the coal mining industry not only improves the safety standards and efficiency of coal mining operations, but also realizes efficient management of complex working environments through technological innovation. It is an important advancement in the field of coal mine safety technology.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate but not limit the technical solutions of the present invention, and any equivalent substitutions of the present invention and any modifications or partial substitutions that do not depart from the spirit and scope of the present invention should be included in the scope of protection of the claims of the present invention.
