On September 4, the 2022 "5g + industrial Internet" on-site work conference hosted by the Ministry of industry and information technology was held in Ningbo. At the meeting, the Ministry of industry and information technology issued the guidelines for the construction of 5g fully connected factories. Why was this national conference held in Ningbo? Zhang Yunping, Vice Minister of the Ministry of industry and information technology, gave an answer. He said, "Ningbo's 5g + industrial Internet enabled manufacturing transformation and upgrading has achieved remarkable results and is in the forefront of the country." Ningbo's leadership is mainly reflected in the "three more" - first, there are many pilot demonstration projects of "5g + industrial Internet". Since 2019, in accordance with the model of "8 + 1 + 1" (leading enterprises in 8 key industries such as textiles, clothing and automobiles + 1 household appliance industry + 1 Chemical Industry Park), the "5g + industrial Internet" pilot program has been launched in the province. It has been listed in 3 integrated innovative application projects of "5g + industrial Internet" of the Ministry of industry and information technology, 40 municipal level pilot projects have been selected, and the annual plan library projects have exceeded 100. The case collection "exploration and practice of 5g fully connected factories" issued by the Ministry of industry and information technology selected 41 demonstration projects of 5g fully connected factories nationwide, of which Ningbo accounted for 9, accounting for more than 20%. Secondly, there are many innovative applications and technologies of "5g + industrial Internet" in Ningbo. Relying on the first 4G / 5G network quality in China, operators and enterprises in Ningbo have created a series of 5g innovation achievements. In the construction of polar krypton 5g smart factory, China Unicom has created a series of 5g + advanced applications such as 5g + MEC, 5g + data collection, 5g + AI compliance detection, 5g + Ar remote operation and maintenance, and 5g + wheel hub detection; In the agcodi 5g fully connected factory, the province's first mobile 5g LAN industrial Internet was deployed online, which completely decoupled the operator's network from the enterprise's network. At the same time, the country's leading 5g modular industrial control terminal was deployed in the factory; Ningbo JieChuang technology has created the first 5g gateway in China, which has been applied in more than 40 5g factories in Ningbo. Recently, JieChuang has launched the equipment nailing system, which enables industrial equipment to become engineers' friends in the "nailing" application. When problems occur, it will send information to engineers independently, and the equipment will also "pull the group" to solve the problems by themselves. Thirdly, there are many scenes of "5g + industrial Internet" in Ningbo. 5g fully connected factories not only refer to manufacturing factories in a narrow sense, but also cover all fields with production sites, such as ports, industries and mines, and power. Ningbo Daxie Merchants International terminal, taking advantage of network resources dominated by Ningbo Telecom, pioneered the use of sd-wan technology on 5g to completely solve the disturbance problem of wireless networks, making wireless networks as stable and reliable as wired networks, and launched innovative scenario applications such as truck unmanned driving, 5g gantry crane remote control, and 5g video scene of patrol cars. "In the next step, Ningbo will, according to the instructions and requirements of the Ministry of industry and information technology, deeply study the guide to the construction of 5g fully connected factories, take this meeting as a new starting point, anchor the goal of building a global city of intelligent manufacturing and innovation, promote the expansion of 5g fully connected factories from pilot to large-scale applications, promote global competition for advancement, strive to create a national '5g + industrial Internet' integrated application pilot area, and strive to:
