China News Service, Wenshan, March 28 (Luo Jie) In the air compressor station of Yunnan Shenhuo Aluminum's 5G Edge Cloud Smart Factory (hereinafter referred to as "Smart Factory"), the noise of machine operation roared throughout the workshop.
In the past, workers needed to perform manual meter reading in extremely high noise every 20 to 30 minutes. "Now, automatic meter reading of air compressor instruments can be realized in real time through machine vision, and the working environment of workers has also been greatly improved. ".
Zeng Yunyu, deputy general manager of the group customer department of Wenshan Branch of China Mobile Yunnan Company introduced.

Recently, the reporter visited the 5G edge cloud smart factory of Yunnan Shenhuo Aluminum and learned that the second phase of the project has completed the infrastructure construction. With the application of 5G+MEC and other technologies, non-ferrous metal smelting enterprises are upgrading toward automation and intelligence.
Yunnan Shenhuo Aluminum Co., Ltd. (hereinafter referred to as "Yunnan Shenhuo") is a branch of Shenhuo Group in Yunnan. In 2019, it settled in Funing County, Wenshan Prefecture, Yunnan Province through industrial replacement, with an annual output of 900,000 tons of electrolytic aluminum.

In June 2020, Yunnan Shenhuo signed a "5G+" smart factory construction strategic cooperation agreement with China Mobile Yunnan Company and ZTE Corporation to jointly build a first-class green hydropower aluminum smart factory in the country.
Wang Pan, director of the Smart Factory Office of Yunnan Shenhuo Aluminum Co., Ltd., introduced the construction of the smart factory. “We build a smart factory based on the principle that we can use machines to work without humans, and can be automated and not manual.”
According to reports, Yunnan Shenhuo relies on the exclusive networking model dedicated to China Mobile's public network, and through in-depth analysis and understanding of the sub-scenarios of the non-ferrous metal industry, it refines 6 typical network requirements and builds the non-ferrous metal industry based on 5G cloud and network integration. Integrated high-quality corporate private network template.
It is worth mentioning that based on the development and application of 5G technology, some of the production difficulties in the electrolytic aluminum industry have been solved.
In the electrolytic anode casting process, the cast iron solution has the highest quality at 1400 degrees.
The traditional measuring method is to judge the temperature from the color of molten iron by experienced old workers.
Now, the professional digital two-color high temperature camera can perform non-contact high temperature measurement of the furnace. The data will be transmitted to the machine vision platform in the machine room through the 5G network, and then the temperature of the molten iron can be displayed in real time through GPU calculations and professional algorithms to ensure that the iron solution is at the best The temperature is out.
The application of this technology improves the electrolytic anode casting process, which improves the anode casting quality by 15%.
At present, the second phase of the smart factory project has carried out multiple explorations of 5G applications, such as 5G-based optical fiber strain temperature monitoring system-electrolytic cell leakage analysis, 5G-based visual monitoring of conveyor belt deviation cracks, and 5G+MEC crane centralized remote control And "5G+" comprehensive positioning, etc.
After the introduction of these applications, Yunnan Shenhuo has greatly improved its safety production and product quality.
In the next step, the industrial Internet platform and the digital twin middle station built in cooperation with China Mobile Yunnan will be completed in June and October 2021, respectively.
Yunnan Shenhuo Aluminum's 5G edge cloud smart factory will focus on the main links and key areas of the construction of electrolytic aluminum smart factories, and orderly promote the overall construction of smart factories.
