(Yanwoling Cement Limestone Mine in Changjiang County.) On September 14, China Mobile Hainan Company and Changjiang Huasheng Tianya Cement Co., Ltd. held a signing ceremony in Changjiang Li Autonomous County, and the two sides worked together to build the "5G Smart Mine Unmanned Driving Project". The project is the first unmanned 5G smart mine project in Hainan, with a planned investment of more than 100 million yuan. It is understood that the project will be located in Yanwoling Cement Limestone Mine in Changjiang County. Relying on the technical advantages of 3D GIS (geographic information system) management and control platform, Changjiang Huasheng Green Mine integrates with China Mobile's 5G private network, Internet of Things, cloud computing, artificial intelligence, driverless and other technology applications to achieve comprehensive intelligent management of mining, transportation, production, sales, engineering geology, safety standards, mine ecology and other information. Through industrial Internet, edge computing, AI algorithm and other new technologies, Achieve a comprehensive perception of the mining area environment, and finally realize the autonomous and intelligent operation of mining equipment such as mining trucks and unmanned aerial vehicles. (Yanwoling cement limestone mine management and control platform.) In terms of unmanned mining trucks, GPS+Beidou satellite navigation is supplemented by base station positioning to achieve three-dimensional high-precision positioning of trucks, and then through 5G network, automatic driving, high-precision maps and other technologies to achieve unmanned mining truck driving and marshalling operations. Technicians introduced that the driverless mine car based on 5G+edge computing platform can not only avoid personnel working in dangerous environments, but also solve the personal safety problems of traditional mine workers; On the other hand, through cloud operation planning, precise control, unified coordination, and coordinated operation with excavators and other equipment, we can reduce the consumption of queuing and congestion during line transportation. Hainan Mobile said that, with the support of Changjiang County Party Committee and Government, it will give full play to its advantages in technology, capital, management and other aspects, accelerate the layout of Changjiang 5G network construction, let more 5G innovative technologies, products, projects and applications come to life in Changjiang, and promote scientific and technological innovation to enable green, sustainable and high-quality development in Changjiang.
