Change in the integration of 5g and industrial interconnection

what kind of chemical reaction will the integration of 5g and industrial interconnection produce? At the 2019 industrial interconnection summit, industrial interconnection platform service providers, telecom operators, industrial enterprises and telecom equipment providers conducted corresponding discussions

at present, 5g industry has commercial conditions from standards, solutions, chips to terminals. So, what are the main application scenarios for 5g and industrial interconnection integration? What new business models may emerge from the integration of 5g and industrial interconnection? What are the specific practical experiences of 5g enterprises? At the 2019 industrial interconnection summit, industrial interconnection platform service providers, telecom operators, industrial enterprises and telecom equipment providers conducted corresponding discussions

rich application scenarios

Shi Heng, technical director of Haier Industrial Intelligence Research Institute and technical director of Shandong Industrial interconnection innovation center, introduced that from Haier's own practice, about 21 specific application scenarios were planned when the 5g joint laboratory was established with China Academy of communications and communications in october2018. However, some scenarios are still far away. However, Shi Heng believes that there are several specific application scenarios that will be applied first

first, machine vision. Machine vision has become more and more popular in manufacturing enterprises. It used to rely on artificial intelligence to detect, but now it is through machine vision, but it puts forward requirements for large bandwidth. Specifically, there is monitoring based on safety management behavior, such as the safety protection of employees in special workplaces, which used to rely on manual supervision and management, but now it needs a lot of data transmission through visual technology and human behavior judgment

the second is ar. AR is not widely used in factories, but Shiheng believes that AR will be of great help to factories, including induction training for new employees, quality testing, and support for remote operation and maintenance

there is also industrial control. Industrial enterprises are worried about the stability of data transmission. Will packets be lost? In addition, mobile terminals have been applied in factories, such as UAV and AGV car, and will be more and more popular in the future

Rong lotian, marketing director of Foxconn fuhuake Precision Industry (Shenzhen) Co., Ltd., said that Foxconn has explored 5g technology for nearly two years. The simplest is the need for some mechanical data testing machines, which are mobile devices, such as AGV cars. Foxconn has made a very in-depth exploration. The other is about the exploration of cutting tool equipment. At present, there are nearly 100000 CNC machine tools in Foxconn, and it is necessary to observe the status of each knife in the most direct way. Since a knife rotates 200000 times per minute, it involves the rapid installation of vibration sensors, which must be done wirelessly. In addition, the tool replacement and power supply are just needed, which are important application scenarios for 5g

5g will promote new business models

5g will bring new business models to operators, which is the consensus of operators. Zhang Yong, President of China Unicom Network Technology Research Institute, believes that 5g is both a new challenge and a new opportunity for operators. In the industrial field, operators should first do a good job in pipeline and bearing. At the same time, operators should not only carry, but also start from the terminal. It is reported that in the 5g project of Qingdao port, China Unicom has provided the most advanced R & D of industrial customs, the launch of products, and end-to-end adaptation

of course, there are many industrial scenarios that can not be completed by simple network access. There are also future operation services, including long-term maintenance services, upgrade services, and even further analysis and operation support services based on industrial big data

wangxiaoqi of China Mobile believes that operators are best at providing pipelines, but after 5g, it is certainly not just providing pipelines, but in terms of business model

first of all, from 2G, 3G to 4G, the 2C mode made by operators is relatively simple and successful. But when it comes to 5g, the highlight should be on the industry, including industrial interconnection, including automatic driving, intelligent medical treatment and education, which are the key service areas of 5g. It is different from 2C in terms of network operation and maintenance, network construction and charging mode. This is a big point of view. Different service objects will lead to great changes in the whole business model and operation model

secondly, 5g has a great impact on the whole business model. It should be slicing and edge computing. 5g with slicing and edge computing is the 5g that truly meets the needs of the industry. In terms of slicing, one is to provide bandwidth and the other is to provide traffic. In addition to the traditional 5g, it will also provide sliced network resources. Whether it is frequency, transmission resources or network resources, different slices can be used to ensure different SOAs, so as to provide the entire communication service for different scenarios. Different services and scenarios have different requirements for network bandwidth, network resource consumption and the complexity of the operator's operation and maintenance system, which will bring changes to the specific billing model and business model

Hongdanke, director of Communication Department of system operation Department of China Southern Power Co., Ltd., introduced the experience and thinking of 5g application of China Southern Power Co., Ltd. It is reported that in recent years, Nanfang electric power company has continued to promote the transformation of intelligent electric operators, which requires transparency of the status of electric equipment, electric operation status and market transaction status, involving a large number of sensor devices, including monitoring equipment and acquisition equipment, which puts forward high requirements for communication

in order to truly achieve smart electricity, we must first cover the distribution layer of thousands of households. At present, most of these services are narrowband, broadband, real-time and reliability. However, at present, these different demands are basically supported by the public, and the exclusive coverage is less than 2%. Therefore, the configuration layer faces a new challenge, that is, the low-cost coverage of mass terminal communication

in the face of these challenges, Nanfang power carried out some research on 5g in cooperation with relevant manufacturers and operators, followed up in 2017, and jointly promoted with some manufacturers in 2018, including the application of 5g standard in electricity, the release of white papers on the power industry, and the safety isolation analysis of 5g. In 2018, Nanfang power established a special working group within the company, and formally became a member of 3GPP and CCSA. It began to work to incorporate smart power demand into 5g international standards, and has submitted 14 power demand proposals to 3GPP

hongdanke believes that 5g network meets the needs of intelligent power development and provides a better solution for distribution and communication services, especially to meet the requirements of ubiquity and full coverage. The three technical features of 5g provide differentiated network service capabilities for different services of electricity. In particular, the network slicing technology provides safe isolation capabilities for different service partitions

"5g technology will certainly bring profound changes to the development of intelligent electricity, especially the application of a large number of intelligent sensing devices with troublesome consequences, which will help make electricity transparent and perceptible, and truly realize the interconnection and perception of all things." Hongdanke said. It is revealed that Nanfang power will carry out a lot of work in Guangzhou and Shenzhen in the next two years to form a sharing and win-win mechanism with operators and create a benchmark vertical industry application

5g network construction takes three steps

zhaoweiduo, director of the Internet industry of ZTE Co., Ltd., said that 5g applications are divided into two major aspects in the industrial field: in plant and out of plant, and the operation network from Ethernet to below in the plant is a process of increasing difficulty. Generally speaking, the initial applications are first concentrated outside the factory, such as remote maintenance and remote monitoring, which will involve costs and manpower. The first step in the factory is to replace the existing WiFi network

from the perspective of the landing time of 5g industrial applications, in the short term, data collection will be the main demand before 2021, which is the most basic demand of industrial applications. In the medium term, real-time control or high-precision positioning in some factories may be realized. In the future, wireless flexible intelligent factories will be finally realized to realize flexible production lines and flexible production

Zhao weiduo introduced that industrial ar will be an important application of 5g. The combination of the two can be applied to several major fields. The first is digital design collaboration. Engineers no longer need to do some actual simulation models. Wearing ar glasses, they can be free from space constraints. Of course, the construction and development of AR content still needs time; The second is remote operation assistance, including sales, marketing products, etc., which are practical application scenarios, and which customers value more. Thirdly, machine vision. At present, most of machine vision is wired. In the future, 5g, which has the ability of low delay and large bandwidth, will be placed in the cloud for processing. The requirement for the distance between the r-test piece center and the disk rotation axis center of local computing power will be greatly reduced

the construction of enterprise 5g network can be divided into three steps. The first step is to build enterprise 5g wireless quasi specialized network to replace the existing WiFi network and wired IP. The diversion can be realized through edge computing. Enterprise data can be directly returned to the local server of the enterprise after mobile edge computing. There is no need to bypass the public of the operator to eliminate the concerns of the enterprise about data security. The second step is moving edge computing. 5g can use moving edge computing to process the data in the process of collecting data. Step 3: in the future, all equipment and production units in the factory will be combined wirelessly
