Discussion on industrial internet technology framework of smart mine

Aiming at the problems of information island,data quality and network information security in the process of intelligent mine construction,this paper analyzes the current situation of smart mine construction technology framework,and compares the relationship between smart mine construction and coal industry internet.The main methodology is ISO/IEC/IEEE42010 system and software engineering standard,The Internet architecture system of smart mine industry is put forward,including four system construction of “network,logo,platform and security” of equipment layer,edge layer,enterprise layer and industry layer,it expounds the five layer architecture of smart mine industry internet platform technology,and analyzes the main contents and interrelations of each layer,including ①Site layer,providing data sources and process optimization scenarios for industrial equipment and business management; ②Edge layer,an edge cloud computing architecture based on the integration of OPC UA and TSN is constructed to realize the closed-loop edge application of perception,interconnection and computing; ③IaaS layer,to build a storage and computing architecture based on edge cloud collaboration,to realize the virtualization and pooling of network,storage,CPU and other resources; ④Industrial PaaS platform layer,including general resource deployment and management,mining big data engine,mining mechanism and big data modeling analysis,mining digital twin information model modeling engine and development environment based on micro service framework and components; ⑤The industrial SaaS application layer calls and encapsulates the development tools,mine mechanism model,data-driven model and other services on the industrial PaaS platform to develop intelligent mine business operation and mine intelligent application APP. It also discusses the construction of “smart mine brain” enabling intelligent mine based on PaaS platform of smart mine industry internet operation system,The main application scenarios are mine resource exploration,digital collaborative design,mine construction management,integrated automation integration,intelligent mining,rapid excavation,geological survey management,fault diagnosis,〖JP2〗intelligent logistics,intelligent ventilation,accurate perception,major hazard identification and control,emergency rescue and long-range supervision and supervision. Finally,the summary and prospect are given.
