Recently, the parallel forum of "Industrial Internet enables high-quality development of enterprises" of China Enterprise Forum was held. The participants made suggestions on improving the construction of industrial Internet network, platform, security and other systems, and using the industrial Internet to promote the transformation and upgrading of enterprises. At present, China's industrial Internet has covered 45 major categories of the national economy. Accelerating the integration and application of industrial Internet has become a key move for enterprises to stimulate endogenous power. Gao Chunlei, Deputy Secretary of the Party Committee and Executive Director of China Iron Tower Co., Ltd., said that the development and application of the industrial Internet provided a realistic possibility for industrial enterprises to achieve intelligent control, operation optimization and industrial collaborative innovation. The deep integration of information and communication technology represented by 5G and industrial technology promoted the innovation and upgrading of the industrial chain, innovation chain, talent chain and value chain, and further promoted the high-quality development of industrial enterprises. "Data comes from industry and serves industry. As data becomes a new factor of production, enterprises face the problem that massive data is difficult to use effectively, and call for new industrial infrastructure to play a role, establish production factors with data as the core, and drive the change of production mode." Xiao Xue, the executive president and chief engineer of Inspur Group, said that on the basis of massive data, we should focus on production intelligence, form a production model with orders as the core and industrial chain supply chain coordinated pull through demand adaptation, distributed factories, social resource allocation and other links, and continue to enable large-scale enterprises to achieve intelligent production and small and medium-sized enterprises to achieve large-scale technological transformation. Many industries are actively exploring innovative applications of industrial Internet. Zhu Minghua, deputy general manager of Jiangnan Shipbuilding (Group) Co., Ltd., said that the current transformation of ship products has accelerated the transformation of manufacturing form, from a single low value-added ship type to the development of batch and far-reaching "double high" equipment at home and abroad, from a single point of promotion to the collaborative innovation and integrated development of the industrial chain and supply chain. Industrial interconnection promotes the management and control of manufacturing process from second level to millisecond level, the integration of multiple data of human, machine/equipment and environment, and the total quality management under the digital condition. It is necessary to build a cloud platform for supply chain collaboration, promote model-based connectivity between assembly plants and suppliers, improve agile response capabilities, enhance supply chain resilience, and create new value for customers. Wang Congxiao, member of the Party Committee and deputy general manager of Capvision Technology Group Co., Ltd., introduced that Capvision Technology Group is accelerating its exploration of the industrial Internet enabled glass industry. Among them, in industrial Internet plus+digital R&D, digital twin technology is applied to R&D and design. Through knowledge model and big data machine learning training, formulas and products are constantly fitted to provide the industry with R&D and new generation information technology integration services. With the help of the industrial Internet, enterprises are accelerating their transformation and upgrading, and the role of improving quality, reducing costs and increasing efficiency is emerging. Lv Qinghai, senior vice general manager and chief information officer of Sany Heavy Industry Co., Ltd., introduced that Sany Group has realized the networking of 73000 terminals at the manufacturing end and 17000 operating equipment, with the operating efficiency increased from 30% to 70% and more than 90% of key equipment.
