In the process of promoting the intelligent construction of coal mines, the phenomenon of "digital divide" and "information isolated island" has appeared in many systems. The precious data generated by each system cannot be deeply utilized, and it is difficult to form a unified information resource. In the intelligent construction of coal mines, the main problems are as follows:

There are many information systems, and the same basic data is defined differently in different systems, which cannot guarantee the uniqueness of the same object code and the consistency of upstream and downstream management specifications.

The professional subsystems of "mining, excavation, machinery, transportation, communication, and safety" involved in coal mine safety production work alone, and cannot form an integrated management platform for the entire production process.

With the development of mobile informatization, more and more applications have begun to expand to the mobile terminal. However, at present, there is a lack of unified management. Each system is developed relatively independently. The entrance cannot be managed uniformly.

Based on this background, Yiri Technology independently developed an intelligent integrated management and control platform for mines. The coal mine's business modules such as human and vehicle positioning, equipment management, broadcast scheduling, monitoring and monitoring, production, sales and transportation are integrated into the mine's intelligent integrated management and control platform, the data is stored in a unified data warehouse, and a comprehensive display of the data is realized through a map. , and then realize a series of applications such as intelligent scheduling, intelligent production, intelligent safety, and intelligent decision-making in the process of intelligent management and control of coal mine safety production, promote less human and unmanned mining in mines, and achieve safe, efficient, and green operations.

Platform Features

1. Multi-source data fusion

The platform has unified data interface specification, unified data coding standard, unified data storage management, effective integration and data fusion of multi-source heterogeneous data.

2. Information linkage application

Predetermined system linkage rules to realize regional linkage, alarm linkage, system linkage and other functions.

3. A GIS map

The mine information model is constructed through the organization of spatial geographic coordinates, and all personnel, equipment, sensors, environment and other data on the mine well and underground are defined in layers, and multi-layer 3D visualization is displayed on the GIS map. It has functions such as transparent information sharing, implementation tracking, trajectory playback, and multi-level zooming, which play an important basic supporting role in the management of underground personnel, equipment, and the environment.

4. Intelligent decision analysis

Establish data warehouses, knowledge bases, and use big data analysis technology to mine and analyze data to provide decision-making support for managers.

5. Customized development

According to the status quo of coal mines and application needs, on-demand customized function development services.

6. Mobile APP

The intelligent integrated management and control platform for mines is equipped with a mobile APP. The mobile APP has functions such as personnel positioning, vehicle management, route planning, alarm and early warning, equipment management, and voice and video communication.

3D visualization

It supports digital definition and 3D modeling of the composition, characteristics, and functions of physical entities in main places such as underground tunnels, mining faces, pump rooms, and substations, and completes mapping in virtual space to realize 3D display of production scenes and dynamic data. real-time monitoring.
