From November 25 to 28, the 2022 Boao Forum for Chinese Entrepreneurs was held in Boao, Hainan. At the 2022 Boao Science and Technology Innovation Conference sub forum held on the 27th, Xinhuanet, together with China Electronic Information Industry Development Research Institute, released the Digital Economy and Real Economy Integration Development Report (2022). Haier, Sinopec, Ali and other 20 enterprises were selected to provide experience and reference for the innovation practice of digital integration and the exploration of digital economy development. Haier Group has two cases selected into this authoritative report: one is the intelligent manufacturing practice of Zhengzhou Water Heater Factory, and the other is the construction practice of enabling Dongying Kenli Intelligent Chemical Park. Lighting up the "beacon" of intelligent manufacturing, the water heater industry has entered the stock market. The consumer demand has changed from purchase to upgrading. The "value" of products has become a more core pursuit of consumers, which also puts forward higher requirements for the upgrading of industry technology. Healthy, intelligent, scene based and personalized have become an important trend of water heater products, and also an important track for differentiated competition in water heater plants. As the world's first end-to-end "lighthouse factory" in the water heater industry, Zhengzhou Water Heater Interconnection Factory promotes the digitalization and intelligence of the whole process, as well as the interconnection of human-machine and object, and the end-to-end information integration. By connecting various elements such as employees, machines, and users, it realizes the real-time connection and intelligent interaction between upstream and downstream enterprises and users, and promotes the intelligent control, system optimization, quality and efficiency improvement of factory production. It is reported that Zhengzhou Water Heater Interconnection Factory plans 11 flexible assembly lines, 15 intelligent module areas and 3 sets of intelligent logistics systems, and applies 43 industry-leading manufacturing technologies. 5G, simulation, big data and other industrial core technologies are deeply integrated with advanced manufacturing technologies, realizing digital simulation research and development of products, supply chain data sharing, intelligent scheduling of production processes, and high-precision, zero defect end-to-end intelligent manufacturing. The digital report card is also gratifying: the order response lead time is accelerated by 25%, the production efficiency is improved by 31%, the product quality is improved by 26%, and the non warehousing rate reaches 85%, leading the manufacturing scale and level of domestic water heater interconnection plants. Building a new highland for industrial digital upgrading Under the urgent task of digital transformation, the challenge for chemical enterprises is even greater. Most chemical enterprises belong to high energy consumption enterprises, and their production is characterized by high temperature, high pressure, flammability and explosiveness. Hazard sources and pollution sources put forward higher requirements for environmental protection, safety and other issues in the park and enterprise emergency management. The construction practice of Dongying Kenli Smart Chemical Park, which was selected as the "2022 China Digital Model Project Case", has brought a new smart solution to the industry. In view of the pain points of the isolated and uncoordinated park system, the lack of safety early warning plan, and the lack of scientific basis for investment promotion, Caos applied the "Park OS+Industrial App" integrated solution to build a "fire line" of safety production for real-time perception, dynamic monitoring, risk early warning, and agile emergency response. It can not only realize six integrated regulatory scenarios of safety, environmental protection, energy, emergency, closure and operation, and integrated intelligent service scenarios of logistics, investment promotion, office and government affairs, but also support industrial synergy for the park
