With the full coverage of underground 5G network, the mobile communication technology represented by 5G has strongly promoted the vigorous development of mine intelligent equipment and technology. Cuncaota Coal Mine actively explores the application of new technologies and new processes. * * * Together with factory technicians, the data of equipment parameters, operation processes, remote monitoring, experience base and equipment historical maintenance records are built into a data cockpit, which is integrated into a 5G industrial explosion-proof intelligent AR helmet. The high-definition micro-display screen is located below the line of sight, and the display effect is equivalent to a 7-inch flat panel. It can be used as a dashboard. AR technology can be used to realize equipment maintenance and debugging, remote assistance and remote after-sales service at the production site, and can be adjusted to a position that does not interfere with the line of sight when not in use.
The first set of equipment and technology, such as "moving frame with machine+memory coal cutting+centralized control", used by the fully mechanized mining team in this mine at present, is the first application in this mine. When the patrol personnel in the team encounter a patrol project that is difficult to make decisions or an emergency failure, and cannot solve the on-site problem with their own knowledge, experience and existing data information, the complex scene can be directly transmitted to the factory from their first perspective through the intelligent AR helmet camera, and the technicians in the factory can provide remote assistance anytime and anywhere. Because it is the inspector's first perspective, technicians can directly superimpose the digital information on the object of operation on the inspector's field of vision as if they were observing it in person, and the on-site inspector can deal with thorny problems as if it were on-site expert guidance, which greatly reduces the communication cost and shortens the troubleshooting time.
In addition, operators can collect real-time information of underground workers, including video, audio and images. Accumulate a large amount of data, realize the precipitation of all kinds of knowledge and digitalization of advanced experience in the process of safe production, and provide necessary and reliable operational support and experience inheritance for the digital operation and maintenance of smart mines.
Next, Cuncaota Coal Mine will continue to expand and develop "5G+AR" multiple application scenarios, combine smart helmets with the digital management platform on the job site, break through the bottlenecks of coal mining enterprises in the operation and maintenance of intelligent equipment and the training of advanced technical personnel, vigorously build a talent system suitable for intelligent development, and start a new journey of "second venture".
