Textile industry application case
1. 5G+ Smart Factory Solution Background
The company is a textile enterprise that mainly produces knitted casual clothing and has vigorously developed sportswear in recent years. It is one of the top 500 private enterprises in China in 2020, and is also one of the important enterprises in Ningbo Municipal Government's efforts to promote 5G + Internet.
2. Demand analysis of 5G+ smart factory solutions
The construction of 5G + smart factory mainly builds enterprise private network through 5G + MEC, and launches 5G + AGV, video surveillance and other scenarios. Through the application of 5G high bandwidth and large link capacity, the AGV car can run stably, and the high-definition video monitoring carried by the AGV can pass the 5G network. Data transmission is carried out to improve transmission efficiency.

With the advent of Industry 4.0, the production model of factories is also undergoing a transformation, from traditional manual operations to unmanned ones. In this process, more and more intelligent handling equipment, such as AGV trolleys/forklifts, are used to replace workers to perform some specific tasks, thereby reducing the workload of workers, reducing the occurrence of accidents, and improving the operational efficiency of enterprises.
The application of artificial intelligence in industrial production must first rely on wireless communication technology. In the past, WIFI was generally used to transmit AGV operation information, but WIFI has several obvious defects:
λ The coverage is limited, the number of APs is large, and the probability of system failure is high;
λ High installation and difficult maintenance;
λ has poor scalability;
λ The packet loss rate is large, especially when the AGV operates in the frequency switching area.
The usage mode and value of AGV trolley/forklift are shown in the following figure:

With the development of 5G technology, it is also an inevitable trend to use more advanced communication technology to improve the informatization degree of factories. In this project, a 5G industrial gateway is loaded on each AGV/forklift, and the communication link between the Unicom 5G base station and the management platform is opened up, which can achieve efficient, stable and fast data collection and reverse control.
An example of the actual rendering of AGV trolley/forklift 5G transformation is as follows:
Through the construction of 5G+MEC private network, enterprises use 5G to implement 5G intelligent connection to production, sales and after-sales links, open up the production process of the enterprise, build a 5G-enabled fully connected intelligent manufacturing factory, and launch 5G+AGV smart cars to replace The personnel carry the material up and down, which greatly saves the labor cost. Data collection and transmission through the 5G gateway improves the efficiency and accuracy of collection and transmission, and implements applications such as equipment predictive maintenance based on analysis.
