Zte, together with the world’s largest steel enterprise Baowu Group, created the construction plan of “Industrial field network + digital Nebula” to enable 5G fully connected factories in WISCO Co., LTD., and completed the global launch and large-scale commercial use of 5G industrial control private networks, truly realizing “full connection”.

By defining new types of industrial control computing power nodes, industrial control private networks, industrial control edge cloud and industrial control value-added services, the industrial field network will integrate the computing network into the industrial field, accurately match the business scenario requirements at the factory level, workshop level and production line level, and realize the deep integration of OT/IT/CT. Production line level, workshop level industrial control network deployment is fast, low cost, agile and reliable; Factory level industrial control network wide area connection, extreme security, CNC and data do not go out of the park. On the industrial site network, the enterprise digital platform built based on ZTE Digital Nebula can flexibly select atomic capability components according to the actual production needs of different user departments, quickly launch business, and help enterprises develop with high quality.

In terms of industrial site network, ZTE has created an exclusive 5G industrial control network for different branches of WISCO, providing an integrated solution integrating “end”, “edge”, “cloud”, “network” and “industry” with 5G industrial control computing power base in the typical production links of the steel industry such as material selection, iron making, steel making, continuous casting, and steel rolling, and fully promoting the “less humanized, unmanned, and centralized control” of the steel site. On the one hand, 5G industrial private network helps maximize the value of 5G in 3D job scenes, achieve efficient collaboration between processes, and finally completely eliminate anomalies through on-site unmanned; On the other hand, to achieve the scale of the value scenario, through the improvement of safety, reliability and economy, the value scenario can be widely deployed in the factory.

In the iron and steel industry hot metal transportation scenario, the locomotive and tank car for the transportation of hot metal need to be transported from the iron plant and the steel plant, the transportation distance is more than a few kilometers, at the same time, the traditional operation needs to have locomotive drivers and schedulers working on the site, the working environment is poor, and the safety risk is high. By building a factory-level industrial control private network, ZTE ensures the safety and reliability of the network in a wide range of production control scenarios through the exclusive use of core network elements, so that the safe and stable operation of hot metal transportation can be improved, and the unmanned rate of the scene can be improved, while ensuring the safety of the operation, the scheduling efficiency of hot metal can be improved, and the energy loss caused by the drop in iron water temperature can be reduced.

There are a large number of shop-level scenes such as crane control in raw materials, transit, finished product warehouses, etc. In recent years, the transformation process of WISCO Limited unmanned intelligent reservoir area has accelerated to release 3D post on-site workers and improve logistics coordination efficiency. Zte adopts 5G dual-band dual-link + dual-send and receive technology, and innovatively creates a computing power base station based on shop-level distribution, which realizes the safe and stable operation of unmanned control of the crane with a minimalist networking and lightweight method, thereby reducing job safety risks and accelerating the turnover efficiency of raw materials and finished products. In the hot rolling, cold rolling and silicon steel workshops of WISCO, the unmanned business scale of more than 40 vehicles has been realized.

In terms of digital production, WisCO has built a steel digital platform based on ZTE Digital Nebula on the base of the cloud network, taking production lines, workshops and factories as units, and closely combining actual production needs to form an overall plan for factory construction or transformation.

In the production line, with the deepening of the industrial structure adjustment and transformation and upgrading of the steel industry, WisCO vigorously promoted the “Baoluo” robot, more and more positions began to implement “machine replacement”, and the application of AI detection showed rapid growth. Zte Industrial AI+ big data detection solution is based on the digital nebula base, which is applied to the sintering process optimization control, AI online quality inspection, rolling process determination and other steel industry scenarios. Wisco Limited Practice has integrated more than 100 kinds of AI algorithm models for 10+ industries, while supporting low-code, drag-and-drop application development methods to help end users quickly build business. At the same time, it can provide AI BOX, industrial computer, edge cloud and enterprise private cloud and other deployment modes, aiming at enterprises of different sizes and different business scenarios, to achieve cost-effective service deployment.

In the workshop, ZTE Innovation integrates 5G positioning technology with traditional satellite, Bluetooth /UWB and other positioning technologies, carries out a variety of 5G positioning technology verification outside the plant, in the plant, underground oil depot and other scenarios, forms a multi-scene integration of positioning capabilities, provides end-to-end solutions for location services, and enables the digital transformation of the steel industry. In the silicon steel workshop of WISCO Co., LTD., 5G fusion positioning is combined with modern management technology to comprehensively perceive the people, equipment and environment in the factory, establish efficient connection between the huge environment of the factory, complete the 3D modeling of the rolling steel production line through digital twin technology, combine the production positioning information of people and objects in the workshop, and combine the operation of the production system with enterprise management. Provide services for personnel management, equipment and materials management.

In the future, ZTE will continue to promote and deepen the model of “industrial field network + digital nebula”, optimize the production value chain of process manufacturing, enhance the production agility of discrete manufacturing, comprehensively promote intelligent manufacturing, and build ubiquitous industrial intelligence.
