  • Detail

The four application scenarios of "5g+ industrial interconnection"

with the accelerated construction of new infrastructure, 5g and industrial interconnection, as their main fields, have attracted much attention and continued to heat up

5g is a new generation of mobile communication technology, which can not only bring good mobile Internet experience, but also become a key supporting technology in the fields of intelligent manufacturing, intelligent medical treatment, intelligent government affairs, intelligent city and automatic driving; The industrial interconnection platform is a top-level ecosystem that represents the general direction of deep integration and innovation of the new generation of information technology and manufacturing industry. It includes not only hardware fields such as production equipment, materials and products, but also various management software, data and services

5g opens a new digital era of Internet of everything. Industrial interconnection is the main application scenario of 5g. 5g + industrial interconnection will be an important direction of industrial integration, which can further promote the efficient collaboration among various production factors and help enterprises realize digital transformation and upgrading

● scenario 1: perceptual management of production process ●

in the traditional industrial era, production equipment, raw materials and energy are the three basic elements of industrial production. The development history of traditional manufacturing industry is actually the history of material production by enterprises using production equipment, raw materials and energy. Every technological revolution in the field of production equipment, raw materials and energy has led to the change of production mode and the leap of productivity

however, in recent years, with the rapid development of new generation information technologies such as IOT, mobile Internet, cloud computing and big data, more and more production equipment and parts have realized the interconnection with interconnection or other terminal equipment in a wireless manner, thus deriving industrial interconnection

with the increasingly deep integration of information technology and manufacturing industry, the trend of industrial production towards digital transformation and upgrading is becoming more and more obvious. Digital knowledge and information data have become the key production factors of enterprises (as shown in Figure 1)

5g can support the connection of millions of objects per square kilometer, and provide industrial reliability and real-time. These capabilities make 5g a key infrastructure to support the smooth implementation of the industrial interconnection strategy. It is this upgrading of large-scale connectivity that makes production resources, information data, goods and materials, production equipment and employees fully interconnected

in the future, through comprehensive interconnection, new technologies such as cloud computing, big data and blockchain will be combined with automation technology to realize vertical integration of production processes. The collaborative cooperation between equipment and between employees and equipment will connect the whole factory. They can make requests and respond to each other in a timely manner, and can also adjust the amount of resources used and the productivity of products, Carry out personalized flexible production

in the era of industrial interconnection, enterprises must ensure the interconnection between basic production processes and goods, materials and equipment, so as to perceive various data required for real-time decision-making

on the one hand, sensors are distributed throughout the production equipment of the enterprise, and the system can continuously perceive data from various processes to ensure real-time update of data; On the other hand, by integrating data from enterprise operation systems (ERP, etc.), business systems (MES, etc.), suppliers and customers, we can comprehensively, dynamically and in real time control all processes of upstream and downstream links of the supply chain, so as to improve the overall efficiency of the enterprise supply chain

in industrial interconnection, on the basis of the original automatic control function of equipment/production line, by adding the new function of perception, the requirements for intelligent indicators such as production safety and product life cycle management can be realized

these sensing functions attached to the production equipment mean that by configuring many IOT sensors or 5g wireless network communication modules for the equipment/production line, the perceived information data are transmitted to the data center or intelligent computing center behind the industrial interconnection platform through the wireless network, and then intelligent decision-making is realized through big data analysis, so that the equipment/production line has the functions of visualization, controllability, automation and self optimization, So as to realize the intellectualization of equipment/production line and form a perceptual management production process (as shown in Figure 2)

by perceiving data and mining and analyzing big data, the future production process can realize high reliability and high stability operation, each production link can be clearly visible, and the manual intervention can be minimized, so that the whole enterprise can operate automatically in an orderly and efficient manner

after the formation of perceptual management of the production process, enterprises can master the status of production resources in real time; At the same time, as the circuit between the main body of the product life cycle management system and the production scheduling system and the force measuring device is optimized by plug connection, the use of raw materials and energy consumption will be more economical, thus further promoting the cost reduction and efficiency increase of the enterprise

through perception, enterprises can identify various abnormalities in the production process, monitor production safety, timely repair equipment, reserve and supplement inventory, and find and solve quality problems in advance; Through perception, enterprises can predict output and sales based on the comparative analysis of historical data and real-time collected data, so as to improve production efficiency, product output and quality, timely adjust production scheduling and supply, marketing and inventory system, and prevent production safety and other problems

based on the above characteristics, the enterprise can comprehensively and real-time control the production management system and various resources, effectively respond to the challenges brought by various internal and external uncertainties, more flexibly respond to diversified and personalized market demands, and more flexibly respond to the changing upstream differences: the needs of upstream suppliers and downstream customers

● scenario 2: early warning management of equipment status ●

in the industrial 3.0 era marked by automation, enterprises have increased the proportion of equipment assets while reducing labor costs, which makes the remote diagnosis and operation and maintenance services of equipment face great challenges. Because no matter how automatic the equipment is, it can not avoid problems such as wear and aging; At the same time, the manufacturing industry is an industrial field with the assembly of parts and components as the main process. Due to the high complexity of the structure and technology of machining equipment and the difficulty of equipment maintenance, the equipment has frequent failures and serious damage, which restrict the improvement of the enterprise's equipment management level

through 5g + industrial interconnection, enterprises can further enhance their grasp of equipment status, and ensure that production scheduling and other decisions are more reasonable and accurate through real-time monitoring, tracking, alarm and other means. The management system can foresee the upcoming problems and challenges, and actively respond in advance, rather than waiting for the problems to occur before passively responding

it is reported that Bosch has cooperated with Nokia to carry out factory wireless test. The data shows that 5g has lower delay and higher stability than Wi Fi and 4G. Bosch said that compared with the large-scale stop of the factory production line, the loss of short-term stop of some key processes is greater, and the key to those processes with high precision requirements is rapid response (low time delay). In other words, the key production tasks need to ensure the stability, reliability, sensitivity of the network and the high speed required for large flow data analysis and processing

it is difficult to lay optical fiber in traditional factories, while wireless communication technology Wi Fi is difficult to expand, and its speed and anti-interference performance are not strong. The delay of Wi Fi in the manufacturing workshop may lead to high costs, such as limiting productivity improvement and reducing profits

in some enterprises in developed countries, mobile Internet connection has been more widely used than Wi Fi. In order to take advantage of higher data speed and reliability, many enterprises are considering building 5g local area networks. Compared with 4G, 5g can support more devices besides 10 times faster (or more) and 50 times slower

with the arrival of 5g era, there will be more 5g local areas in the industrial interconnection field. Compared with other local wireless networks, the main advantages of 5g local area network are: higher capacity to support more devices, high bandwidth applications, wider range, seamless mobility, industrial reliability, consistent delay, higher service quality and security, and interoperability with multiple suppliers upstream of the industrial chain

wi FI is a wireless network communication within a certain range. Generally, the effective coverage of radio waves is only tens of meters. It can send and receive large-capacity data without any cost. Therefore, it is widely used in enterprises, parks, stations, shopping malls, hotels and other places. However, compared with mobile communication, Wi Fi has security problems. As long as you master the user name and password on Wi Fi, anyone can access the network. At the same time, Wi Fi is not stable enough, and often drops when used for a long time, which determines that the key processes of the enterprise cannot fully use Wi Fi. In the 4G era, the maximum download rate is 100mbit/s and the upload rate is 50mbit/s. The transmission will be delayed. It is difficult to send large capacity data such as audio, video and HD images in real time. The 5g local area network not only has the advantage of Wi Fi without communication costs, but also can adopt SIM authentication. Without going through the public, it can achieve security, special use, high speed, high reliability and low delay

for example, after the German Bosch Company adopts 5g local area network, connect the electric screwdriver to the special network, and the data information such as the number of turns and sequence of screwing will be automatically recorded. Bosch tests or verifies industrial engineering management and other solutions with the help of 5g, which not only keeps the quality of all manufactured products balanced, but also reminds and corrects in real time when the screw tightening sequence is wrong. Moreover, the electric screwdriver can feed back all industrial engineering data to the server at the same time, which can not only facilitate industrial engineering management, but also provide available information for other products

Bosch used to implement this management process based on Wi Fi. Later, it was found that 5g local area has better performance than Wi Fi in terms of anti band interference, bandwidth (especially upload), overload and network security. Different production lines in the factory may use different networks, so sometimes the production lines may have to be changed according to needs, and the network versatility of Wi Fi is poor. In the future, industrial production will use a large amount of data. The product development of mass production and sales will change to meet the personalized and customized needs of customers. The low universality of Wi Fi will be a major constraint

from the perspective of improving efficiency and reducing cost, the network in the factory also needs to be wireless. In order to improve product quality and productivity, many factories continue to promote automation, and the control of robots also needs to be wireless and real-time. However, with the expansion of factory scale and the complexity of industrial engineering, 4G is sometimes difficult to deal with, and 5g is expected to solve these problems

for example, Audi adopts 5g local control industrial robot and AGV handling robot. In some key processes that need to manage a large number of equipment, it can also achieve high stability, ultra-low delay and the same performance as the wired network. At the same time, the weight of various data generated by industrial engineering is more than 5% less than that of conventional aluminum alloy. It can also be collected into edge terminals or cloud computing through 5g local area in real time, and processed through artificial intelligence to achieve intelligence

Audi controls the AGV handling robot through 5g local area to deliver the required parts for the automobile manufacturing production line in real time, so as to realize the in plant logistics intelligence

in Germany, 5g has become an important infrastructure for Industry 4.0. In addition to Audi, Daimler, Volkswagen and other automobile manufacturing enterprises, petroleum, chemical, harbor and other enterprises婴儿消化不良吃什么药
