Click the mouse and the heavy equipment in the workshop will start automatically; Open the mobile app and all kinds of data in the production process can be seen at a glance; On the big screen presented in real time, every corner of the factory has a panoramic view... When the traditional factory meets 5g, these "future factory" scenes once appeared in science fiction films become a reality. 5g + industrial Internet is promoting the leap of traditional industries from "manufacturing" to "intelligent manufacturing". The reporter walked into factories and revealed how 5g shaped the "future factory". Walking into Huaxin Cement (Huangshi) Co., Ltd., we see crisscross pipelines and huge production equipment, and the low roar comes out from time to time. This is the raw material workshop of the cement plant. The machines are produced 24 hours a day, but there are no busy workers in the plant. In the office building not far from the raw material workshop, the large screen in the central control room shows the real-time production picture of the whole factory. The staff only operate on the digital system, and the corresponding physical production links will run according to the instructions. "For example, to adjust the opening of the damper, I only need to input the corresponding value on the computer, and the damper will automatically open to the desired size." The operator Xu Liyang entered the value "25%" while introducing. "According to the traditional production mode, the production posts in the factory need more than 500 people, while the application of the 'smart factory' now only needs more than 200 people." Liu Wenbing, executive general manager of the company, said. Using intelligent equipment for automatic production not only reduces manpower, but also greatly improves efficiency. Several cylindrical sensors can be seen at the fan of the raw material workshop. "These sensors can detect the temperature, vibration and sound of the device, and the detection data will be automatically sent to the mobile app synchronously." Luo Yazi, a staff member, showed the intelligent patrol inspection system on his mobile phone and said, "in the past, manual patrol inspection could only report problems by phone, which was easy to delay the production progress. Now, when the intelligent patrol inspection system detects abnormalities, the patrol inspectors will immediately receive alarm messages and respond quickly." People have the impression that the "silly big black thick" steel plant can also be green and intelligent in the 5g era. In the operation centralized control center of China Baowu Echeng Iron and Steel Co., Ltd., hundreds of LCD screens on the upper and lower floors are very spectacular. The large screen displays the real-time pictures and data of each production link of the factory. Yan Jiansheng, director of the control center of Echeng Iron and steel production and manufacturing department, said that the operation control system, decision support system and operation centralized control system all operate in the 5g private network. 114 operation rooms originally scattered in various areas of the site, such as ironmaking, steelmaking, steel rolling, energy, environmental protection and remote metering, are concentrated into this centralized operation control center. 5g technology has the characteristics of high speed, large bandwidth and low delay, which ensures the accurate control of the system, making one key steelmaking, intelligent opening and blocking of iron port, automatic tapping of converter, etc. a reality. "Through three-dimensional modeling, the remote one key iron port opening and blocking technology of Hubei iron and steel can understand the situation in the furnace in real time, and carry out real-time regulation and control on various indexes, composition and other coefficients in the blast furnace." Yan Jiansheng said. In the operation centralized control center, several flashing red rectangles in the picture of liquid metal production line are particularly eye-catching. Ding Dongru, chief engineer of the steel plant, said that this is an electronic fence. Each worker wears a work card equipped with 5g + Beidou satellite positioning system. Once the worker approaches the dangerous area designated by the electronic fence, the work card will give an alarm. "In the past, scalding was common in steel mills. Now with the electronic fence, the safety of workers has been guaranteed." Ding Dongru said. In addition to ensuring the personal safety of production personnel, 5g + industrial Internet is also used in the food and drug industry to ensure product safety. In the drug extraction workshop of Wuhan Aimin Pharmaceutical Co., Ltd., pipes are connected with tanks of different shapes. "In the process of drug production, if the control is not effective, the operator is likely to become the largest pollution source." Liu Jun, chief engineer of Aimin pharmaceutical, introduced that the intelligent production system ensures that the whole production process is carried out in the tank, which greatly reduces the possibility of drug pollution. 4G changes life and 5g changes society. With the accelerated integration of new generation information technology and traditional factories, 5g + industrial Internet will further consolidate the base of digital economy development and enable intelligent upgrading of thousands of industries. "In the near future, more and more factories will become smarter, more efficient and greener 'future factories' with 5g energy." Fan Bingheng, general manager of China Mobile Hubei company, said.
