[0032] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1 As shown, the coal mine intelligent mining integrated management system described in the present invention includes several end sides, edge sides and cloud sides;

[0034] like Figure 2As shown, the end side includes a data acquisition module, a data cleaning module, and a data forwarding module

[0035] Among them, the data collection module collects data from each equipment data center in the mine in real time through restful API & database reading operations; the equipment data center includes the centralized control data center, controller data center, equipment management data center and equipment data center;

[0036] The data cleaning module organizes the data format according to business rules to facilitate unified data processing; for example, the group code + mine code + working face code combination is used as the data label, and abnormal data is deleted, and the null values ​​in the data are supplemented according to the data type;

[0037] The data forwarding module automatically forwards the cleaned data to the data storage modules on the cloud and edge sides through Kafka (a high-throughput distributed publish-subscribe messaging system).

[0038] like Figure 3 As shown, the edge side includes a data calculation module, an event alarm module, and a device posture adjustment module;

[0039] The data calculation module calculates and analyzes the received terminal data according to the corresponding data model;

[0040] The event alarm module determines whether to trigger an event alarm based on the calculation and analysis results of the data calculation module, and issues an event alarm 24 hours in advance. In event applications, the accuracy of event alarms reaches more than 90%;

[0041] The equipment posture adjustment module adjusts the equipment posture, such as the lifting and lowering of the hydraulic support, the movement of the coal cutter, the speed of the scraper transport, etc., based on the calculation and analysis results of the data calculation module and the comprehensive geological data, such as the thickness of each layer;

[0042] At the same time, the edge side provides data reading and permission control for edge side users to ensure data security;

[0043] like Figure 4 As shown, the cloud side includes a machine learning module, an equipment failure analysis module, a production process and reserve analysis module, an energy consumption analysis module, and a visualization interface;

[0044] The machine learning module uses machine learning algorithms to generate corresponding data models for the received end-side data, and sends them to the edge side to guide the edge side to issue event alarms and adjust the device posture.

[0045] The equipment failure analysis module intelligently analyzes the possible causes of equipment failures based on the received terminal data, the equipment life and service life, geological information and other related data, and assigns different weights to the causes of the failures. It can generate analysis results at the same time as the fault warning is issued. The probability weight of the first cause exceeds 60%, and the precise positioning accuracy reaches 80%;

[0046] The production process and reserve analysis module builds a simulator to optimize the production process based on the received end-side data;

[0047] The energy consumption analysis module analyzes the energy consumption of devices based on the received end-side data, helping users better manage device assets, issue inventory warnings in a timely manner, and analyze increased losses.

[0048] Visualization interface, which visualizes the cloud-side analysis results and corresponding data, including a 3D model for production process optimization;

[0049] At the same time, the cloud side provides data reading and permission control for cloud side users to ensure data security;

[0050] In addition, the end side, edge side, and cloud side all have data quality monitoring modules to monitor their own data transmission and data consistency. When data transmission is interrupted or data values ​​or sequences do not meet business rules, an alarm is immediately issued and the relevant responsible persons are notified.

[0051] The cloud side adopts a server cluster architecture, which includes at least one master node, one manager node and one node node. The node heartbeat is automatically detected through the task management and resource scheduling module. When the master node heartbeat is lost, the services and data of the master node are automatically migrated to the manager node. When the node heartbeat is lost, the services and data of the lost node are migrated to other node nodes or the master node. At the same time, by monitoring the CPU and memory usage of the entire cluster, as well as the resource usage of services and data, nodes are automatically allocated to achieve resource balancing.
