In the era of high-speed, large-bandwidth, and low-latency 5G, not only will mobile phone speeds double, but it will also empower major industries, promote the development of the industrial Internet, and help the manufacturing industry improve quality and efficiency and the real economy. Upgrade.
Based on 5G, the cable "tail" of the machine will become history, remote control of the robot becomes possible, the AGV robot in the factory area will realize automatic cruise, and the warehouse will realize unmanned management. At present, the flexible production based on 5G has come into reality. 5G brings not only the improvement of the network, but also the improvement of the production process, and it also brings the reconstruction of the entire factory structure.
The trolley automatically runs to the warehouse
Through the centralized control and scheduling of the 5G network, the smart car can drive along the prescribed guidance path, count parts and drive operations. This is the scene in the province's first 5G﹢MEC edge computing smart workshop created by China Telecom Zhejiang Company and Chint Group. Based on the high bandwidth and low latency characteristics of the telecommunications 5G network, the trolley is equipped with AGV (Automatic Guidance Equipment) control terminal software to realize the unmanned operation of the warehouse.
Walking into the digital workshop of Zhejiang Zhengtai low-voltage electrical appliances, at a glance, we can no longer see the pipeline of workers working at their desks. Instead, they are busy and flexible mechanical arms, welding robots with flashing lights, and automatic packaging machines that flip up and down... The industrial Internet cloud platform is the "brain", the information system is the "neural", and the automatic guided unmanned AGV logistics system is the "blood", which realizes the efficient integration of various functional areas and the orderly production rhythm. Concerto for Smart Manufacturing.
Huang Bingrong, deputy general manager of Chint (Yueqing) Science and Technology Innovation and Entrepreneurship Park Co., Ltd., introduced by Zhengtai Group with all its efforts and is about to complete the construction of the Internet of Things Sensor Industrial Park, said that 5G empowerment will make the transformation and development of enterprises more possible.
"The realization of wireless flexible production is like the previous production line from 1 to 10. The replacement of the production line requires a new production line. Now we can reorganize the combination, flexibly and reliably deploy, and effectively reduce the cost of network deployment and maintenance."
Body welding has "5G supervision"
In the factory area tens of meters away, dozens of robots are waving their arms, welding up and down against the car frame, and splashing red sparks from time to time. "It turns out that these welding machines need to be connected to the server with a network cable and have a long tail. However, the deployment cost is high, the construction period is long, and the debugging is limited by the location. The use of 5G communication makes the deployment of the group control system flexible, and the on-site debugging is no longer affected by the location. Limitation, also saves manpower and improves work efficiency." Zhang Suqiang introduced that after using the telecommunications 5G network, a server can control the welding equipment of the entire workshop, can record the welding process parameters in real time, traceability and improve welding quality.
For car manufacturers, flashing vehicle software is a big problem. Because a car generally has 30 to 40 vehicle-mounted control units, and the module software varies in size, it takes more than 1 hour to flash a single car, which seriously affects the vehicle's offline speed. The existing vehicle flashing method generally adopts the VCATS equipment-network cable-OBD-vehicle method. The distance of the flashing is limited by the length of the network cable, and cannot be remotely flashed. After using 5G wireless technology, it can realize unattended flashing in the coverage area of 5G network and flashing in transit, which greatly expands the scope of the flashing area. "It used to take 1 hour to flash the software, but now it only takes a few minutes. 5G is indeed a great tool for improving efficiency." Geely engineer Xie Zhipeng said.
In the remote control center on the second floor of the Geely Automobile Research Institute, engineers can remotely see the working conditions of the factory robots in real time, and can also view various data in real time. "We used to go to the site to see the robot's failure before. Now we just look at the data and use VR technology to remotely diagnose the failure, and give preliminary conclusions." Engineer Wang Jianwei said that the use of 5G network transmission speed characteristics can be achieved The three-dimensional scene of the remote factory is tracked and reproduced in real time, and the relevant personnel can understand the factory status more intuitively.
It is reported that in the verification center of Geely Automobile Research Institute (Ningbo) Co., Ltd., the currently successfully tested 5G application scenarios include vehicle software flashing, PTL logistics system real-time connection, logistics warehouse stacker information interaction, AGV system information interaction, BOSCH group control Remote management of systems and factories.
"5G+ Industrial Internet" in Zhejiang
The Ministry of Industry and Information Technology proposed on March 24 to implement the "5G+Industrial Internet" 512 project to create a batch of "5G+Industrial Internet" internal network construction and transformation benchmarking network and model projects. Zhejiang’s actions are relatively fast. In addition to the “5G+ Industrial Internet” practices of Zhejiang Telecom, Chint and Geely, enterprises such as Zhejiang Mobile have also taken the lead in layout.
Following the establishment of the nation's largest 5G trial network in Hangzhou, Zhejiang Mobile took advantage of the first-mover advantage of 5G, played the role of the 5G industry alliance, and intensively promoted 5G, artificial intelligence, Internet of Things, cloud computing, big data, edge computing and various The integration and innovation of large industrial applications have formed 21 application demonstration sites.
At the end of March, Zhejiang Mobile announced a major breakthrough in the 5G industrial Internet-through cooperation with Hangzhou Steam Turbine Group, Zhejiang Central Control, Xinan Chemical and other companies, research and implementation include 5G 3D scanning modeling and detection system, instrument wireless reduction and upgrade The first batch of 5G industrial Internet applications in the province and other provinces have all entered the pilot stage.
"Since October 2018, we and Hangzhou Steam Turbine Group have been continuously communicating on the topic of 5G technology combined with industrial Internet exploration and innovation. We have established a 5G intelligent manufacturing innovation laboratory, which covers 5G network coverage, terminal products and Hangzhou Steam Turbine applications. The connection of scenarios and needs, combined with the resources and capabilities of third-party software developers and mechanical equipment manufacturers, and the technical support of communication equipment manufacturers such as Huawei, create and incubate innovative applications of 5G industrial Internet to promote the high-quality development of equipment manufacturing "" Zhejiang Mobile staff introduced.
In the operation workshop of Hangzhou Steam Turbine Group, the staff is using a sophisticated electronic scanning device to perform a three-dimensional scan of a cylinder device. On the other side of the workshop, a three-dimensional model of the physical scan is simultaneously displayed on the screen of a computer device . By comparing with the standard model, the computer can determine whether the product error rate is within the normal range in real time. If the product is qualified, the graph is displayed in green, and if it is not qualified, the graph is automatically displayed in red.
The staff of Hangzhou Steam Turbine Group said that blades and cylinders are one of the core components of industrial steam turbines. The parts and components manufactured by Hangzhou Steam Turbine according to customer needs are of a tailor-made structure with complex shapes and high precision requirements. In the past, traditional testing procedures required manual and equipment combination. The testing time for one blade required 2 to 3 days. The products produced by the outsourcing unit also need to be specially sent for inspection. Therefore, the quality inspection can only be carried out by random inspection. "The 5G 3D scanning modeling and detection system currently built in cooperation with Zhejiang Mobile can accurately and quickly obtain 3D data on the surface of the object and generate a 3D model through laser scanning technology, and transmit the measured massive data to the cloud in real time through the 5G network. The server quickly processes the comparison, determines whether the solid 3D model is consistent with the original theoretical model, and simultaneously feeds back the results to the factory in real time. The system reduces the detection time from 2 to 3 days to 3 to 5 minutes, on the basis of achieving full product detection A quality information database has also been established to facilitate the analysis and tracing of quality problems in the later period, which not only saves costs but also directly improves the benefits. The system has been put into trial use in the static workshop of our group, which is mainly used for quality inspection of twisted blades and cylinder blanks. Test comparison."
