Henan: 5G Builds a Solid Foundation for "Digital Central Plains"
2023-12-04
Recently, the reporter followed the "Seeing the Digital Central Plains -2023 World 5G Conference Media Camping Event" to Henan and visited Jinling Coal Industry, Tianrui Cement, Zhengdong New Area CBD and other places, conducting on-site investigations and interviews in the front line. They witnessed firsthand the disruptive changes of digital technologies such as 5G, cloud, AI, and big data on traditional industries, and truly felt the vigorous pulse brought by digital technology to economic development. In a mine that is nearly a kilometer deep in digitalization, where machines enter and people retreat, frontline miners can have high-definition video calls with the ground by holding a 5G intrinsically safe mining phone; At the ground level dispatch center, staff can operate the entire production process by lightly clicking the mouse and typing the keyboard. On the open-pit cement limestone mine with high mountains and steep slopes, excavators remotely controlled through 5G networks load ore onto unmanned mining trucks. In the intelligent control room several miles away, the driving situation and ore transportation data of the unmanned mining trucks can be seen at a glance through the live broadcast of the mine's unmanned driving system on a large screen. The same scenario of "machine" entering and "human" exiting also occurs in industries such as power and manufacturing, where the digital construction of smart mining, smart power, and smart manufacturing is changing traditional industries at an unprecedented speed. "Even robots are saved." At the Jinling Coal Industry Dispatch Center, a staff member excitedly told reporters that in the past, robots were still needed to pick out coal gangue in the coal selection process. Now, intelligent selection systems directly achieve the separation of coal and gangue, and are more precise and efficient. According to Shen Zulin, Deputy Chief Engineer of Mechanical and Electrical Engineering at Jinling Coal Industry, the construction and operation of an intelligent application system with "one brain, one network, and one map" has not only achieved seamless communication between the mine and underground, but also achieved remote centralized control of the main equipment in the coal mine, intelligent integrated control of risk control, hidden danger investigation and treatment, and remote technology application of equipment failures. The application of 5G intelligent systems has enabled centralized control of equipment such as underground power supply, belt transportation, drainage, air pressure, and auxiliary transportation systems. The number of workers per shift in the comprehensive mining face has been reduced by 30%, and the number of people entering the well per day has been reduced by 38. The efficiency of a single shift has been improved by 30%. The construction goal of "mechanized personnel replacement, automated personnel reduction, and intelligent operation" has been preliminarily achieved, laying a solid foundation for the mine to achieve a high-quality and safe production level. Tianrui Group Zhengzhou Cement Co., Ltd. Wangzongdian Cement Limestone Mine is an open-pit mine. Statistics show that major safety accidents in open-pit mines previously occurred mostly in the transportation process. Nowadays, 5G networks enable remote control of excavators and unmanned mining trucks to be applied. The reporter learned from the website of the People's Government of Henan Province that Henan Province regards the intelligent construction of non coal mines as an important means to solve the problems of small scale, poor management level, and low mining efficiency in mines. It aims to enhance the capabilities of mechanized mining, information supervision, and intelligent early warning, and promote intelligent personnel replacement and reduction through mechanization. As of now, 5 open-pit mines in the province have basically achieved unmanned operation, 10 open-pit mines have basically achieved remote control of shovel loading operations, built intelligent comprehensive control platforms, completed the intelligent transformation of 211 auxiliary systems for lifting transportation, ventilation and drainage, and completed the unmanned replacement of 1928 positions. Local operators in Henan are also increasing their efforts
