At present, the new generation of information technology represented by 5G is developing rapidly and accelerating its application, while the construction of new infrastructure represented by the Industrial Internet of Things is promoting the digital transformation and development of traditional manufacturing. Relying on my country's largest 5G network in the world and a series of policies issued by the country, "5G + Industrial Internet of Things" has become one of the most active industries in application innovation.
In recent years, China Mobile has given full play to the technical characteristics and advantages of 5G enabling industrial applications to promote the integration and innovation of "5G + Industrial Internet of Things". Promote the 5G network to become the network infrastructure of the factory, gradually cover 5G technology to most application fields of the factory, penetrate into all aspects of factory production operation and management, comprehensively improve the efficiency of production operation, and continuously promote its digitalization, networking, Intelligent development.
Today, the editor will take you to take a look at how the traditional mining industry in the Inner Mongolia Autonomous Region has been upgraded to a smart mine with the help of 5G.
Smart mine makes production work faster
"No. 101, No. 101, please answer when you receive it. You have been stranded at your location for 5 minutes. Do you have any questions?"
"Everything is fine, ready to move on."
This scene happened in the production management center of Laoshidan Intelligent Mine in Wuhai City, Inner Mongolia Autonomous Region. Safety.
The Laoshidan mining area in Wuhai City is 7.12 kilometers long, 1.7 kilometers wide, and covers an area of 9.7764 square kilometers. The coal mine was built in 1965 and put into production in May 1970. The approved production capacity is 1.50Mt/a, and the recoverable reserves are 40.99Mt. After being transformed into an intelligent mine, automatic mining has been realized underground, and the production dispatching center can monitor and manage the underground status in real time. The sense of security, comfort and happiness of miners in smart mines has been greatly improved. All these changes are due to the 5G smart mining platform jointly built by China Mobile Inner Mongolia and China Mobile Shanghai Industrial Research Institute.
Smart mines make production work more efficient
Today is the day for Xiao Wang to go to the mine. Through facial recognition, Xiao Wang opened the wardrobe without a key. After changing into work clothes, wearing a safety helmet, wearing a self-rescuer and a smart miner's lamp, everything was ready, Xiao Wang walked to the mouth of the auxiliary shaft, and when he came to the mouth of the shaft, AI intelligent detection helped him complete the safety inspection, and at the same time inspected all equipment configurations. Wear it correctly. Xiao Wang got on the explosion-proof vehicle and walked slowly to the mining face. The mining robot was activated through the centralized dispatching platform to realize automatic mining and transportation. In the underground, Xiaowang's intelligent miner's lamp system can also detect the underground environment and gas conditions in real time.
The staff of the Laoshidan Smart Mine looked at the slowly moving mine carts on the big smart screen, and sighed with a smile: "In the past, there was no data signal underground, and the communication could only rely on the intranet landline. After the miners finished the mining work, they couldn't find the mine. They can only rely on blind guessing to find mining vehicles, and the work efficiency is very low. Now, with the 5G individual equipment provided by China Mobile, miners can not only communicate underground, but also dispatch vehicles in an orderly manner in the intelligent waiting hall. People don’t look for cars, cars look for people.”
In the past, Laoshidan Intelligent Mine had many systems including wired, wireless, broadcasting, security monitoring, video, and personnel positioning. The systems could not be combined and integrated, and each went its own way. It was an isolated island of underground information. The main transportation system still adopts the form of manual inspection, and the environment of the main transportation system is complicated, noisy, and there are health risks. When excavation and fully mechanized mining work are carried out underground, underground workers are still mainly operating on site, and there are potential safety hazards. In order to solve this problem, the intelligent mine upgrade combines 5G core technology and big data, and plans virtual interactive applications based on 5G technology, ultra-high-definition video, intelligent working face, remote real-time control, remote collaborative operation and maintenance, underground inspection and security, etc. Coal mine underground application field. At present, a total of 45 sets of China Mobile 5G base stations have been installed underground in the Laoshidan Intelligent Mine, and the coal mine road and underground have achieved full coverage of 5G signals.
Smart mines make production work safer
In terms of safe production in smart mines, the panoramic working face roaming system is a panoramic picture of the working face assembled by installing 16 high-definition cameras on the 16402 smart working face. It is also a window for mine road personnel to understand the safety production situation of the working face. The key technology of AI inspection is used in the main transportation system and the intelligent inspection system, and realizes data sharing with the main transportation related equipment, and immediately uploads the identification information to the dispatching hall in the form of early warning and alarm, providing assistance and monitoring for the on-duty personnel. Multi-gas detection sensors, real-time monitoring of CO, H2S, CH4, O2 gases underground, equipped with smoke detection sensors, to test the smoke concentration in the roadway environment, and realize the over-limit warning function. Equipped with a high-definition camera, it realizes the ultra-clear video collection of the camera in the smart coal mine usage scene, and meets the video monitoring requirements of the robot system for the visible part along the belt. And the video window will pop up automatically during the start-stop operation and when a fault occurs, completing the video linkage logic.
At present, 100% of the fixed positions in Laoshidan Intelligent Mine have been unattended, and a management mechanism of "unified inspection + robot inspection" has been formed. Including power supply, ventilation, pressurized air, nitrogen injection, water supply, drainage, main transportation, cleaning and other 8 systems, 11 fixed positions have actually been reduced from 121 to 39 people, which has truly realized mechanized replacement and intelligent reduction.
Empowered by 5G technology, a safe and efficient era of smart mines is coming to us. The integrated development of 5G and the Industrial Internet of Things is accelerating the construction of a digital China and a smart society, accelerating the process of China's new industrialization, and injecting new momentum into China's economic development.
