## 5 Full Connection Power Transformers for Digital Factory Applications  
In the power transformer discrete assembly manufacturing enterprises, the establishment of full connection digital factory has greatly improved its production efficiency. The manufacturing execution unit and the data acquisition system integrate the physical and network data resources of production line and shop level [38] into the edge computing and cloud manufacturing operation management server. The data generated by the manufacturing activities will be systematically modeled through big data analysis, cloud computing processing, and deep learning, while relying on the advanced data sensing and 5G communication technology. Real-time and high-fidelity manufacturing process synchronization between the workshop and Manufacturing Operation Management Platform. In this process, edge computing will provide some computing power and take some data processing tasks. In addition, the manufacturing operation management platform coordinates design resources and manufacturing resources to split product demand orders, reasonably allocates personnel and materials, and controls the manufacturing process in real time. The whole life cycle of the product and the follow-up delivery logistics are traced using identity resolution technology. The deployment of power transformer discrete assembly and manufacturing full connection digital factory is divided into three parts: automatic production, product quality assurance, and intelligent operation and maintenance of workshop equipment. The production resources of the digital factory are synchronized and coordinated by the manufacturing operation management platform. The intelligent production equipment at the workshop level and production line level has the decision-making authority for some production tasks, such as the planning of AGV material distribution path and the temporary material scheduling in the storage system. At the automatic production level, according to the current order, the digital technology is used for the design of resources and process plan, production team personnel arrangement, work order of each production line, production material allocation, coil process plan, semi-finished products storage, as well as transportation and discrete assembly, finished products delivery, and order delivery to ensure a normal, orderly, and automatic production. The 5G communication base station deployed in the workshop is combined with the workshop positioning technology to perceive the position state depth of AGV. Moreover, cloud computing [39] is combined with the edge computing technology to specifically split the material distribution tasks of each station and rationally subcontract the types and quantities of the materials required by the station and the distribution path of AGV. The AGV equipped with an artificial vision camera can then identify the obstacles on the path. The workshop monitoring system and edge computing platform were combined to avoid obstacles, and the distribution rhythm was adjusted according to the production rhythm. The intelligent warehousing logistics of multiple stations and various materials in the whole distribution process are realized, as shown in Figure 6.  
Figure 6: Intelligent warehousing logistics transportation. In product quality assurance, material quality is closely related to product quality. Using the identity resolution technology, the whole process of the production of product parts, assembly of components, and assembly and delivery of finished products, from the supply from the upstream chain manufacturers to the warehousing and discharging of materials, is assigned to the cloud. The specifications, production date, quality rating, and other information on the materials, as well as the parts and finished products, are input in each flow link to perform the quality traceability of the whole life cycle of the products.
