Technology + policy two-wheel drive, Xinyuan Coal Mine built the country's first 5G + intelligent coal mine
Under the mine, in the electromechanical chamber more than 500 meters deep, the inspection robot is carrying out 360-degree video monitoring, audio acquisition, infrared thermal imaging and other work. In the mine, in the centralized control center, workers can monitor the underground gas concentration, temperature and humidity, coal mining and other data in real time on the electronic screen through computer operation, and the scenes such as comprehensive mining, excavation, and transportation are unobstructed.
This is the working scene of the Xinyuan Coal Mine. From manual inspection to remote monitoring, the operation mode of traditional mines has been completely subverted, and unmanned and intelligent has become the new appearance of 5G-enabled mines.
"Safe production is the red line of the mining industry." With the integration and development of intelligent technologies such as 5G and the mining industry, the operation mode of traditional mines has been completely subverted - from "manual inspection" to "moving mouse", from "manual mining" to "remote monitoring", "5G + industrial Internet" to support the safety of coal miners "umbrella", traditional industries are rejuvenating with wisdom and new vitality.
Xinyuan Coal Mine actively responds to the policies and guidelines of the national and provincial governments in the unmanned and intelligent construction of the coal industry, and cooperates with Huawei, China Mobile, China Coal Science and Industry, Tsinghua University and other relevant units to cooperate and actively innovate, and built the first 5G+ intelligent coal mine in the domestic coal industry at the end of 2020, realizing the visualization, automation and less humanization of the underground part of the work.
Facing the intelligent construction, the traditional network of Xinyuan Coal Mine faces three major challenges
The large-scale application of 5G, artificial intelligence, big data and other technologies in coal mines has greatly improved the working environment of underground miners and improved safety on the one hand, and on the other hand, it has also brought great challenges to the existing coal mine network.
Underground multi-network, high construction costs: The current underground video surveillance, production control, electromechanical monitoring and other different business systems use different ring network bearers, resulting in underground multi-network, high network construction costs; coal mine underground existing network is mostly industrial switch networking, switch equipment does not support time synchronization, network slicing and other key characteristics, does not support 5G bearing.
Increased network bandwidth pressure: Most of the current underground ring networks only have 1gbps bandwidth, while video surveillance ring networks require 10gbps bandwidth. With the large-scale deployment of high-definition cameras for underground comprehensive mining surfaces and boring surfaces, the bandwidth pressure of the ring network is great.
Network difficulty in operation and maintenance: the increase of intelligent applications to promote the continuous expansion of network scale, the traditional network management means is single, network failures often require O&M personnel to go down the well to plug and unplug ports to troubleshoot, fault location time in hours, and even take a few days to eliminate problems, fault location during the production can not be carried out at full speed or even need to be interrupted, affecting coal production efficiency.
Huawei Mine Cloud Network Fusion IP Bearer Solution
Create an efficient, reliable and intelligent network base for Xinyuan Coal Mine
In view of the network challenges in the development of intelligent coal mines, Huawei has launched a targeted mine cloud network solution to provide efficient connectivity for coal mine production, so that the data at the underground production end can go up, and the data center cloud can be intelligent. Xinyuan Coal Mine deployed Huawei's mine cloud network fusion IP bearer solution, using ptn products to build an ultra-wide underground production ring network, with a backbone network bandwidth of 50gbps, and supports upgrading to 100gbps, ensuring the bandwidth required for the backhaul of various types of underground HIGH-definition video in 5-10 years.
Thanks to the guarantee of bandwidth, Xinyuan Coal Mine introduced intelligent inspection robots, before the coal mine underground inspection mainly rely on manual, manpower demand is large, now intelligent inspection machine can be unmanned high-definition video inspection of the underground roadway and the chamber, the inspection workers downhole time reduced by 90%. Moreover, in the past, the calls between underground and ino were all wired telephones, and people had to run to the position of the telephone, which was not only inconvenient, but also could not see each other's images. Now workers can call and communicate with Inoue anytime and anywhere through their mobile phones underground, report safety in time, and make their families feel more at ease.
In order to achieve converged bearer and one-network multi-purpose, the mine cloud network converged IP bearer solution adopts innovative network slicing technology to split a physical network into multiple logical planes that are strictly isolated. Just like on a wide road, a special brt passage is divided with a barrier, and the space of each lane is strictly guaranteed and is not affected by other lanes.
Different network slices carry different services, so as to ensure that high-priority service traffic such as industrial control and voice communication is not affected by other service traffic bursts, making remote control smoother and smoother, voice and video clearer, and realizing reliable communication of downhole services.
For network management, HUAWEI's cloud-network converged IP bearer solution is based on the sdn architecture, which introduces the current detection technology, and the health of the network and the transmission quality of the service traffic can be clearly seen on the big screen of the centralized control center. Once the transmission quality of the service declines, the staff can also carry out predictive analysis and maintenance, and in a few minutes, they can locate which location of the network has a problem, and there is no need for the O&M personnel to go down the well to plug and unplug the optical module one by one to find the problem, which greatly improves the O&M efficiency.
Ji Jie, director of the Xinyuan Coal Mine 5G+ Intelligent Mine Construction Office, said, "We have realized the large bandwidth networking and the one-network bearing of underground multi-service through Huawei's converged bearing solution, and used flexe network slicing technology to ensure the reliability and safety of different services, which well met the business bearing requirements of the Xinyuan Coal Mine 5G+ Intelligent Coal Mine." ”
Xinyuan Coal Mine continues to innovate and leads the intelligent development of coal mines
As a pioneer in the intelligent transformation of the coal mining industry, Xinyuan Coal Mine has achieved fruitful innovative results in business such as unmanned underground inspection, remote control of mining, and integrated bearing of production networks. At present, Xinyuan Coal Mine is still continuing to invest, actively exploring the application of new processes, new technologies and new equipment in coal mines, and continuously improving the level of intelligence in coal mines.
As the world's leading ict infrastructure provider, Huawei continues to focus on the needs and applications of the coal mining industry, and will continue to introduce more reliable, economical, and more suitable products and solutions for the coal mining industry, meet the evolving communication and information needs of coal mines, and make more contributions to the intelligent construction and development of coal mines.
