Smart factories are the core elements of Industry 4.0. In the smart factory, not only the single equipment is required to be intelligent, but also all the facilities, equipment and resources (machines, logistics equipment, raw materials, products, etc.) in the factory are interconnected to meet the requirements of intelligent production and intelligent logistics. Through the communication network such as the Internet, all things inside and outside the factory are interconnected to form a new business model.
In a sense, Industry 4.0 uses the CPS system to intelligently upgrade production equipment, enabling it to intelligently analyze, judge, self-adjust, and automatically drive production based on real-time information to form an autonomous distributed system (ADS). The smart factory ultimately realizes large-scale, low-cost customized production in the manufacturing industry.
When building a smart factory, we must focus on four major technical issues: modularization, digitization, automation, and intelligence. Modularization is the precondition for realizing the large-scale production of smart factories and personalization of customer needs. This requires the transformation of major component suppliers to module suppliers, and participates in product design, supply mode selection and unitized logistics planning.
Digital, vertical view is to realize digital modeling and interconnection of all levels in the factory, and even for each device; horizontally, it is a full-process supply chain integration system from customer requirements to product design, supplier integration, manufacturing and logistics services.
Intelligent, manufacturing companies should build a virtual and real integration system, according to the customer's personalized needs, to achieve virtual design, manufacturing and assembly, and then through the smart factory to complete the manufacturing process, effectively solve the custom product cycle, low efficiency, high cost problem. In the smart factory, enterprises can achieve zero-distance dialogue with customers, and customers can participate in the whole process of product “intelligence” through various means.
