II. Key lessons learned from the "smart change to digital to online" approach
Focusing on key demands such as intelligent manufacturing and flexible production, the company has carried out in-depth construction of new infrastructures such as 5G, big data and edge computing to promote intelligent manufacturing upgrading and key scenario applications with a 5G private network, realizing real-time management of the enterprise's production plan, procurement, warehousing and logistics, quality, production process and production equipment by a cloud-based system, and reaching the goal of constructing a new energy 5G smart factory.
01
In the construction of 5G private networks
Build a fully-connected network based on 5G private network, comprehensively utilizing 700M and 4.9G frequency bands to solve the demand for wide coverage in the park and low-latency and high-bandwidth applications in specific scenarios. 5G technology is combined with industrial control systems to remotely control automotive production equipment, realizing the adjustment of equipment parameters, stopping and starting, and execution of operations.
02
In terms of helping smart production
Using 5G private network technology, the cloud system real-time management of the production process and production equipment, materials from storage to deployment and transportation of the entire digital intelligent management, complete the vehicle chassis, tires and other automotive parts of the fully automated assembly.
03
In terms of production process control
Through 5G industrial gateway + IOT sensors, real-time monitoring of enterprise production status, equipment operation and workshop environment. With the help of 5G network, the collected data will be uploaded to the cloud data platform and analyzed, realizing effective prediction and preventive intervention for events such as product defects, equipment failures and tool failures, helping the smart factory to operate safely and efficiently, and improving the intelligent management level of enterprise industrial control.
III. Main results
Through the construction of Nanjing Changan New Energy 5G Smart Factory, full coverage of 5G network has been realized. Utilizing the characteristics of low latency, high security and reliability of 5G private network data, it has improved the efficiency of factory collaboration and flexible production capacity, making the production beat smoother and increasing the overall production efficiency by more than 10%.
During the period from 2021 to 2023, it will realize the number of concurrent accesses of supported terminals exceeding 50,000, and land 68 typical scenes of intelligent manufacturing in 16 categories, such as 5G+industrial control, 5G+AGV, 5G+machine vision, 5G+data acquisition, 5G+energy control, 5G+welding management, etc., which will be carried out through the whole process of office production business.
Through the digital operation system, the company realizes knowability and visibility, enabling the manufacturing order rate to reach over 90%, the sales order fulfillment rate to reach 100%, and the manufacturing cost to be reduced by 10%. The company was awarded the "Jiangsu 5G Factory Project of the Year 2023", and was selected in the "Directory of 5G Factories of the Year 2023" issued by the MIIT, and won the "Industry Typical Application Case" in the "2023 China 5G+ Industrial Internet Conference". It was also selected as one of the "5G Factory List 2023" issued by the Ministry of Industry and Information Technology (MIIT), and won the "Industry Typical Application Case" in the "China 5G+Industrial Internet Conference 2023".
