This year's government work report proposed to implement the digital transformation action of manufacturing industry, accelerate the large-scale application of industrial Internet, and carry out the special action of digital empowerment of small and medium-sized enterprises. Industrial Internet is a new infrastructure, application mode and industrial ecology that is deeply integrated with the new generation of information and communication technology and industrial economy. Tancheng County, located in the southernmost part of Shandong Province, has the first county industrial Internet platform in Shandong. Here, the industrial Internet enables small and medium-sized enterprises to reduce costs and increase efficiency, cross-border integration of enterprises in different fields, large-scale development of industrial parks, and demonstrates the productivity of industrial Internet. This electronic enterprise in Tancheng County covers an area of only six acres, but its workshop has its own unique features. This 5-meter long production line is equipped with 119 monitoring points to connect real-time production data to the industrial Internet platform, which solves the big trouble of enterprises. According to Zhang Hengrui, the general manager of Linyi Guangfa Technology Electronics Co., Ltd., data statistics from the backend show that the stability of the qualification rate increases significantly when the room temperature in the workshop is below 26 ℃. Small and medium-sized enterprises in distress Industrial Internet has brought about a turn for the better This small enterprise with more than ten people has since become the designated supplier of five well-known leading enterprises. On the industrial Internet integrated service platform in Tancheng, 183 enterprises, most of them small and medium-sized enterprises, have access to data, which requires nearly a million digital transformation and becomes simple under the "application store" service. Guan Xiangzhen, the relevant person in charge of Caos Industrial Internet Platform, said that our solution was divided into several segments, and it might cost tens of thousands or thousands of yuan to solve a small pain point based on a small scenario. Cross border chain building, network building and market linkage not only reduce costs and increase efficiency for SMEs, but also enable different industrial chains to find convergence points. The substandard products produced by this flour company have gone from being a big problem to being a hot potato. Xu Zilei, Director of the Sales and Transportation Department of Wudeli Group Linyi Flour Co., Ltd., introduced that the second flour is located near the surface of the wheat, which is relatively black and does not conform to our current dietary habits. In the past, our products were mainly sold to feed factories. If feed enterprises did not have such a large demand, it would cause a backlog of our products. Through the industrial Internet, the enterprise owner found that the secondary powder was actually the necessary auxiliary material of the board adhesive, and opened a new market in the building materials industry. The "Industrial Internet plus" Park has developed into a cluster of chains. According to the industrial chain map planned by the Industrial Internet, Tancheng has also integrated more than 30 chemical enterprises in the county into a chemical park. Yang Qianpeng, project manager of the chemical industry of Caos Industrial Internet Platform, introduced that the resources of enterprises on the industrial chain can be sorted out. With the platform, the real-time upload of relevant point data information can be realized, and the safety risk prevention and control ability and emergency command efficiency of the park have been improved by more than 50%. Xu Lei, Deputy Director of the Industry and Information Technology Bureau of Tancheng County, Linyi City, Shandong Province, said that this has planned these scattered chemical enterprises into this park, connecting them into chains and clusters. Currently, a green chemical industry cluster worth billions has been formed. China's industrial Internet has covered all industrial categories. At present, China has an influential industrial Internet platform
