Digital model and giant system coupling technology system of smart coal mine

Hundreds of subsystems,such as communication,sensing and control,run synchronously,and form an increasingly complex intelligent giant system in a underground coal mine.Aiming at the problems of lacking of a unified data model,incomplete sensor data and cross-system data fusion in the entire mine intelligent giant system,a unified multi-source heterogeneous data fusion processing method is proposed.A complete digital perception system of cross-system full-time and space information in underground coal mines has been developed based on the data logic model of“hierarchical extraction-association analysis-virtual-real mapping”,which forms a multi-parameter,multi-scale,and full-time-space characteristic data perception scheme that integrates underground production status,mining space information,coal machine equipment status,risk information,etc.Based on the information“entity”and virtual-real mapping mechanism of multi-source heterogeneous relational data in coal mines,the initiative matching,push strategy and automatic update mechanism of information entities based on the knowledge demand model is proposed to solve the problem of real-time data connection and iterative update.The coupling technology of intelligent coal mine system based on ABCD(Artificial Intelligence,Blockchain,Cloud computing and Big Data)is proposed,and the data interaction and fusion process of complex giant system is illustrated taking the coupling of coal mine safety assurance system as an example.A smart coal mine data standard system is established.This paper presents the theory and method of unified data model and decision mechanism of the complex giant system of a coal mine,and establishes the safe,efficient and stable operation system of the smart coal mine system under the multi-objective decision-making.Relevant technologies were applied in the Zhangjiamao Coal Mine of Shaanxi Coal,China,which broken through the integration technology of multiple heterogeneous systems.A full mine cross-domain integrated smart comprehensive management and control platform was built,and a full-time and spatial information digital perception and real-time interconnection mechanism was constructed to open up business data barriers among multiple levels,multiple departments,multiple systems,which achieve the data integration and decision-making optimization of 58 in-use subsystems and 34 newly-built subsystems in the entire mine.
