No one followed the operation. More than 40 automatic guided transport vehicles carried materials in an orderly manner, and crisscrossed paths drew beautiful arcs on the ground... This is the visual impression of the 5g full connection factory of Guizhou Tire Co., Ltd. to the reporter. On the occasion of the third anniversary of 5g commercial use in China, this old tire factory with a history of more than 60 years is becoming more and more energetic due to its active embrace of digital technology. At the factory of the enterprise in Zhazuo street, Xiuwen County, Guiyang City, there are not many workers in some workshops, but the intelligent production equipment has a "sense of existence". What is 5g full connection? Liu Da, a staff member of China Unicom Guizhou branch who is responsible for providing solutions, explained that it is to support a complete production line with 5g private network technology, realize the wireless industrial interconnection and workshop production scheduling of all processes and scenes, digitize each process, and achieve the comprehensive interconnection control of "human, machine, material, method, environment and measurement" elements. Now, with the click of the mouse, the factory manufacturing execution system can be opened on the computer. The progress of each process of tire manufacturing can be seen at a glance. Previously isolated business segments were integrated. Hanhongchuan, head of Guizhou tire information technology department, said that in February 2021, the 5g fully connected factory project was accepted and put into operation. Through the intervention of automation, informatization and intelligence, the production efficiency was improved and the operation and maintenance cost was reduced by nearly one third. Why should a traditional manufacturing enterprise carry out all-round digital upgrading? Hanhongchuan said that in order to cope with the fierce market competition at home and abroad, the enterprise proposed to take the road of "internationalization, intelligence and green". 5g full connection factory is one of the projects. "Many people think that the tire does not have too high technical content, which is just a black knot. In fact, the tire R & D involves comprehensive application in multi-disciplinary fields, and the process requirements of the product manufacturing process are also very complex." He said. "This is the first 5g fully connected factory in Guizhou Province, which really goes deep into industrial production." Yujunjun, deputy general manager of China Unicom Guizhou branch, said that with the support of a 5g network, the factory has realized the flexible production of multiple varieties and specifications of tires, reduced the laying of cables, shortened various construction periods, and increased the annual production capacity by about 120000 pieces. Seeing these achievements, the two sides are still deepening cooperation. 5g full connection factory is only an epitome of Guizhou's acceleration of 5g integration application. According to the information of Guizhou Provincial Communications Administration, in 2022, the province will create 200 5g application scenarios in 18 aspects such as industrial Internet, energy, transportation, education and medical treatment, so as to better boost the 5g empowerment of thousands of industries.
