Every reporter: Liu Ling Every editor: Chen Junjie , each adjustment requires two weeks of shutdown. If one mobile phone every 28 seconds is calculated, one day of shutdown will affect the output value of more than 14 million yuan." Ding Yun, executive director of Huawei Technologies Co., Ltd. and president of the operator's BG, said on May 8 At the "5G Smart Manufacturing Summit", "the use of 5G technology to realize wireless and flexible connection of various equipment in the production line shortens each adjustment time from two weeks to two days, which greatly reduces the loss of production line adjustment."
In fact, in the past two years, not only Huawei, but also leading companies in the manufacturing industry such as Midea Group, Sany Heavy Industry, Liugang Group, etc. have also been exploring the combination of 5G and production factors to promote the "digital-intelligent transformation" of factories. Zhou Ji, an academician of the Chinese Academy of Engineering, also said at the forum that in the future, 20% of the 5G market will be on the consumer side, while up to 80% of the market will be on the industry side.
In Ding Yun's view, after more than two years of practice and exploration, 5G to B has solved many key breakpoints in technology and ecology. 2021 is the first year of commercial use of 5G to B, and the entire industry chain must work together to transform the past. 0-1's innovative results and practices become industry standards, thereby accelerating 1-N replication.
5G commercial exploration for manufacturing enterprises
With the arrival of a new wave of digitalization, 5G, cloud, and AI have become the most critical enablers. As the underlying technology of new infrastructure, 5G has the characteristics of flexible acquisition, high-speed transmission and real-time computing, and is being deeply integrated with different industrial application scenarios.
At the forum, Midea Group IT Director Zhou Xiaoling shared Midea Group's exploration of 5G commercial scenarios. Zhou Xiaoling mentioned that Midea Group has cooperated with Huawei and the three major operators since 2019, and started to do some 5G pilots in AI, security and other aspects.Starting from 2020, Midea Group has further applied it in 11 scenarios.
"Especially in the cloudification of PLC (Programmable Logic Controller), breakthrough innovation has been achieved." Zhou Xiaoling said, "The biggest trouble in our factory is that the PLC is spread over every collection point and equipment in all factories, and the whole debugging, Operation and maintenance are very difficult. After research, it is found that PLC can be made into a cloud and put on the 5G cloud."
"Daily Economic News" reporter learned that Midea Group has realized that all PLCs have been placed in the computer room for unified maintenance. , is currently undergoing the second step of transformation - cloudification of PLC. "PLC cloudification has been successfully researched in the laboratory. Next, we will try it in the factory. If possible, we will carry out comprehensive coverage. It can be said that 5G has greatly subverted the PLC industry."
However, in Zhou Xiaoling It seems that "smart manufacturing" is not the automation of a device or the intelligence of a point. For factories or enterprises, it is necessary to realize the digitization and intelligence of the entire value chain and the entire end-to-end. Therefore, Midea Group also needs to increase investment in the continuous Internet of Things, the de-humanization of quality inspection, the cloud-based coordination of the supply chain, the intelligentization of logistics, and the flexibility of production.
Unlike light industries such as home appliances, daily chemicals, etc., the steel industry has become one of the industries that entered the game late in the era of Industrial Internet+ due to its high security risks.
"At that time, there were also many concerns, because the steel industry had processes for molten metal, especially steel making and iron making. Considering that if all of them were handed over to the Internet, the safety performance could not be guaranteed? But at the same time, the environment for on-site operations in the steel industry was indeed very difficult. It is bad and needs to be upgraded to intelligent manufacturing." Tian Yisheng, general manager of Liugang Group Guangxi Iron and Steel, said.
5G technology has the characteristics of low latency and high reliability. Combined with technologies such as video backhaul and remote control, multiple cranes can be remotely controlled at the same time, allowing workers to stay away from the scene and improving the working environment and efficiency.
Tian Yisheng, for example, said that the entire Liugang Group has more than 1,200 cranes and large mechanical vehicles of various types. Before, these vehicles required manual operation. The strength is relatively high. After the application of 5G technology, remote operation can be realized, the labor cost is reduced by more than 80%, and the efficiency is increased by more than 33%.” Midea Group, Sany Heavy Industry, Liugang Group and other leading manufacturing companies are exploring 5G application scenarios and carrying out "digital intelligence transformation". After more than two years of practice and exploration, 5G to B has solved many key breakpoints in technology and ecology.
As Zhou Ji said on the forum, in the future, 20% of the 5G market will be on the consumer side, and up to 80% of the market will be on the industry side. It is understood that in the past two years, Huawei has cooperated with operators and industry enterprises to explore and commercialize 5G innovations in various industries such as industry, transportation, and energy. Especially in the field of industrial manufacturing, more than 100 5G manufacturing benchmarking projects have been created in more than 10 sub-sectors such as home appliance 3C, steel, cement, petrochemical, and automobile.
However, as a large manufacturing country, my country has 41 major categories of industries, 207 middle categories of industries and 666 minor categories of industries. Among these categories, each industry has different development foundations and different development pain points. In these sub-categories, there is a lack of experience and case reference on how to implement the digitalization of enterprises and how to find a more effective entry path.
Ding Yun also said that 2021 is the first year of commercial use of 5G to B. To accelerate the transformation of "model houses" into "commercial houses" that can be replicated on a large scale, it requires the entire industry chain to join hands and work together to light up 1,000 5G buildings. Smart Factory.
However, achieving this goal is not easy. In Ding Yun's view, all parties in the industry chain need to cooperate in four aspects.
First, to achieve double helix improvement with industry partners. On the one hand, Huawei needs to continue to work with industry partners to explore needs and find scenarios. Industry customers continue to increase 5G innovation and exploration, focus on the information highway to help connect industrial production factors, and find the best 5G scenarios to combine 5G technology with production factors in various industries. .
Second, it is necessary to work with operators to provide 5G private networks with higher reliability and better performance, which will become an important cornerstone of the 5G industrial Internet, and will gradually realize the carrying capacity of 5G multi-network integration in the future. At the same time, the deep synergy of 5G + cloud + AI will penetrate into the core scenarios of OT, and accelerate the digital upgrade of the industry in terms of edge-cloud collaboration, cloud-network collaboration, and full-scenario AI.
Third, the deep participation of application partners is required to expand the use of 5G in the industrial Internet from connection and data base to the entire industry chain such as applications and terminals. From ISVs, to IHVs, to industry integrators, OT+ICT and other partners should be fully convolved and attracted.
Fourth, it requires the cooperation of the entire industry chain to turn the innovation results and best practices from 0 to 1 in the past two years into industry standards, thereby accelerating the replication of 1-N, and making 5G inside a new engine for China's intelligent manufacturing.
