Description

Technical Field

[0001] The present invention relates to the technical field of coal mine water hazard early warning and control, and specifically to a coal mine water hazard intelligent early warning and control system and equipment based on a cloud-edge-end architecture. Background Art

[0002] Coal mine water disasters occur frequently, causing significant property losses and casualties. At present, the industry's research on individual monitoring methods in coal mines is relatively mature, such as conventional hydrological monitoring, electrical monitoring and other monitoring methods, but there are deficiencies in dynamic monitoring and early warning, data integrity, and scene linkage. In response to these deficiencies, the State Administration of Mine Safety Supervision issued relevant documents, requiring all coal mines to connect water hazard prevention and control perception data to the national mine safety production risk monitoring and early warning system to promote the implementation of coal mine information systems and improve the automation and intelligence level of monitoring and early warning systems. Subsequently, various water hazard early warning and control platforms have emerged and are being used by mines.

[0003] However, the existing coal mine water hazard monitoring and early warning platform has the following problems and shortcomings:

[0004] (1) Scattered monitoring methods: Although the existing monitoring methods are relatively mature at a single monitoring point, the overall monitoring methods are scattered and lack unified management and coordination, which makes it difficult to integrate and analyze monitoring data;

[0005] (2) Incomplete spatial coverage of water hazard monitoring points: The existing monitoring points are unevenly distributed, with blind spots, and cannot fully cover all key areas of coal mines, resulting in untimely early detection and early warning of water hazard risks;

[0006] (3) Single warning level: Most existing warning systems can only provide simple threshold warnings and lack comprehensive assessment and multi-dimensional analysis of water disaster risks, resulting in insufficient accuracy and timeliness of warnings;

[0007] (4) Automatic control and linkage are not achieved: The existing flood monitoring and early warning platform only realizes data fusion and visual expression. After the warning is generated, it only notifies the personnel, but does not achieve automatic control and linkage. This not only increases the energy input of the personnel, but also reduces the efficiency of flood prevention and control.

[0008] (5) High system maintenance cost: The need to maintain different systems for flood monitoring and early warning platforms increases the energy input of personnel, resulting in high maintenance costs. Summary of the invention

[0009] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a coal mine water hazard intelligent early warning and control system and equipment based on a cloud-edge-end architecture.

[0010] The present invention adopts the following technical solutions:

[0011] An intelligent early warning and control system for coal mine water hazards based on cloud-edge-end architecture, including:

[0012] Early warning and control subsystem: used to receive water hazard monitoring data and working status, issue analysis parameters, and determine whether there is a water hazard risk warning based on the reported collection data, working status, analysis and calculation data, and early warning parameters. When there is a warning, the system is notified to enter emergency mode to achieve intelligent early warning control;

[0013] Flood monitoring business subsystem: used to obtain various flood monitoring data and results, and notify the data and results to the early warning control subsystem;

[0014] Digital large screen subsystem: used to present the risk status of water hazard monitoring. The digital large screen not only adopts large screen management, but also visualizes and can directly display various data;

[0015] Data networking subsystem: used to achieve seamless data connection and sharing, support the access of external water hazard monitoring system data and the sharing of this system data;

[0016] System management subsystem: used to implement role authority management and authentication, support multi-level authority allocation, meet the needs of different users, and judge and notify the access and sharing status of data;

[0017] Platform management software: used to automate system deployment and installation and simplify system configuration, reducing the learning cost and time cost of installation and deployment.

[0018] Furthermore, the water hazard monitoring business subsystem includes: hydrological basic subsystem, hydrological monitoring subsystem, microseismic monitoring subsystem, rock movement monitoring subsystem, water quality and water source subsystem, which are applied differently according to different monitoring methods and combined with the characteristics of different subsystems to improve professional presentation methods and functions for customers and meet the daily management needs of coal mines.

[0019] Furthermore, the digital large-screen subsystem uses three.js to integrate water hazard collection data, working status, analysis and calculation data, processing results and geological space data through coordinates to achieve four-dimensional visual expression, and present the water hazard monitoring risk status to customers more intuitively.

[0020] Furthermore, the platform management software includes installation package information required for system deployment, and configures the database address and network address on the platform interface.

[0021] Furthermore, the platform management software installs mqtt and registers it to the system service, installs the nodered engine, and installs the database service.

[0022] The present invention also adopts another technical solution:

[0023] A coal mine water hazard intelligent early warning and control equipment, including the coal mine water hazard intelligent early warning and control system described in the first technical solution, and also including edge devices. The edge devices are arranged at various monitoring points and underground equipment control nodes in the coal mine, and are responsible for real-time collection of water hazard data and the working status of each equipment, performing data analysis according to the analysis parameters issued by the early warning and control subsystem, and performing emergency control, and reporting the collected data, working status and analysis results to the early warning and control subsystem.

[0024] Furthermore, the intelligent early warning and control equipment also includes: water hazard monitoring equipment, which is responsible for collecting water hazard data from various monitoring points underground in the coal mine in real time, including water level, water pressure, water quality, and flow rate, and is directly connected to the early warning and control subsystem through the Internet of Things communication protocol or through the edge device.

[0025] Furthermore, the edge device specifically includes:

[0026] Data acquisition module, used to collect water hazard monitoring data in real time and receive data from water hazard monitoring equipment;

[0027] Data transmission module, used to upload the collected data to the early warning control subsystem;

[0028] The data analysis module is used to analyze the parameters issued by the early warning control subsystem to determine whether emergency control measures need to be taken;

[0029] The emergency control module is used to perform emergency control based on the analysis results, including controlling the charging of the smart power supply and starting or stopping the equipment;

[0030] The status reporting module is used to report its own collected data, working status and analysis results to the early warning control subsystem.

[0031] Furthermore, when the communication of the intelligent early warning and control system is interrupted, the edge device can work autonomously to perform data collection and emergency control.

[0032] Furthermore, the early warning measures of the intelligent early warning and control equipment include: sound and light alarms from water hazard monitoring equipment, notifications via SMS, WeChat, and mobile phone apps, and displays on a digital large-screen subsystem.

[0033] The present invention provides a coal mine water hazard intelligent early warning and control system and equipment based on a cloud-edge-end architecture, which is based on a cloud-edge-end architecture of microservices. The intelligent early warning and control system cooperates with edge devices and water hazard monitoring equipment to achieve the linkage between the upper-level information platform and the lower-level equipment.

[0052] The present invention also discloses a coal mine water hazard intelligent early warning control device, including the coal mine water hazard intelligent early warning control system described in the first embodiment, and in addition, it also includes edge equipment and water hazard monitoring equipment.

[0053] Edge devices are installed at various monitoring points and underground equipment control nodes in coal mines. They are responsible for real-time collection of water hazard data and the working status of each device. They perform data analysis based on the analysis parameters issued by the early warning control subsystem, conduct emergency control, and report the collected data, working status, and analysis results to the early warning control subsystem. When the communication of the intelligent early warning control system is interrupted, the edge devices can work autonomously to collect data and conduct emergency control.

[0054] Edge devices include:

[0055] Data acquisition module, used to collect water hazard monitoring data in real time and receive data from water hazard monitoring equipment;

[0056] Data transmission module, used to upload the collected data to the early warning control subsystem;

[0057] The data analysis module is used to analyze the parameters issued by the early warning control subsystem to determine whether emergency control measures need to be taken;

[0058] The emergency control module is used to perform emergency control based on the analysis results, including controlling the charging of the smart power supply and starting or stopping the equipment;

[0059] The status reporting module is used to report its own collected data, working status and analysis results to the early warning control subsystem.

[0061] The early warning measures of the intelligent early warning and control equipment include: emergency control, water hazard monitoring equipment to send out sound and light alarms, SMS, WeChat, mobile phone app notifications, digital large-screen subsystem display, to achieve dual early warning of notification and automatic control.

[0062] Combination Figure 2 As shown, in actual application:

[0063] The water hazard monitoring equipment collects water hazard data from various monitoring points in the coal mine, including water level, water pressure, water quality, and flow rate, and connects them to the early warning control subsystem through the IoT communication protocol directly or through edge devices.

[0064] The early warning control subsystem receives data from the flood monitoring business subsystem and data from edge devices or flood monitoring devices, performs data analysis, and sends analysis parameters to edge devices. The edge devices perform data analysis and report the collected data, working status, and analysis results to the early warning control subsystem. The early warning control subsystem determines whether there is an early warning or flood risk based on the reported collected data, working status, analysis and calculation data, and early warning parameters. When there is an early warning, it notifies the edge device to enter the emergency mode, and transmits the early warning data and other data to the digital large screen subsystem for display. In order to control the emergency, the alarm is activated at the same time and notified via SMS, APP or other external services.

[0065] The digital large-screen subsystem not only receives warning data from the early warning and control subsystem, but also receives direct water hazard collection data from the water hazard monitoring business subsystem for display, intuitively presenting the water hazard monitoring risk status to customers.

[0066] Embodiment 3

The front end uses vue / react to separate data views and uses virtual DOM for component development. The data storage mainly uses open source MySQL, supplemented by redis.

[0068] Combination Figure 3 As shown in the figure, the intelligent early warning and control system for coal mine water hazards includes the following components: user end, reverse proxy server, API Gateway, unified authentication (user center), backend service, data storage, and configuration center.

[0069] Users access the system's front-end page through a browser or through a mobile device (such as a mobile phone). Nginx is used as a reverse proxy server to receive requests from the user end. API Gateway is used as the entrance to the system, responsible for request routing and load balancing. According to the request path, the request is distributed to different services. The user center performs identity authentication and matches the corresponding control authority. The back-end service includes multiple microservices, such as mine water service, 3D modeling service, large screen service, extension service 1 (backup) and extension service 2 (backup). Each service is responsible for specific business logic and data processing to support different subsystems. For data storage, MySQL is used as a relational database to store structured data, and Redis is used as a cache database to improve data access speed. MinIO is used as a file storage service to store unstructured data, such as pictures, videos, etc., and the configuration center provides dynamic expansion and contraction capabilities of services and performs system configuration.

[0070] The components of the above-mentioned coal mine water hazard intelligent early warning and control system cooperate with the subsystems of Example 1 to perfectly build a platform for intelligent early warning and control of coal mine water hazards. At the same time, in conjunction with edge devices and water hazard monitoring equipment, the entire coal mine water hazard intelligent early warning and control equipment can realize the linkage between the upper information platform and the lower equipment, thereby improving the control capabilities of intelligent early warning and making it more automated and intelligent.

[0071] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention.
