• The Industrial Internet will be the cornerstone of the fourth industrial revolution and one of the key areas of new infrastructure construction. It has important strategic significance for industrial transformation and upgrading and supply.side structural reforms. Based on the current technological risks in the construction and application of the Industrial Internet and the trend of the industrial revolution, this article uses the “product = material + process冶 as the model, combined with blockchain and trusted computing, and proposes a self-organization of the supply chain as the core driving force of the Industrial Internet. The proposal puts forward a ring.shaped Industrial Internet architecture, as well as the basic ideas and guarantee operation mechanism of the supply chain self-organization process. It is suggested that the construction of the core driving force of the Industrial Internet should be based on the principle of“ a game of chess in the whole country冶and increase investment in basic scientific theories. Finally, this article looks ahead to the impact of the Industrial Internet on industry, society, and a new generation of artificial intelligence

• Abstract ( 314 ) 　　
• As a typical representative, a chemical company has the characteristics of complicated processes, production scenes, equipment factory lines, etc. , and there are a large number of high-density ubiquitous connection scenes, accompanied by harsh environments such as high temperature, poisonous gas, dust, and flammable explosions. In these high-risk scenarios, because traditional wireless data transmission methods such as 3G, 4G, and Wi-Fi cannot meet the requirements of low latency, high reliability, and anti-interference, data collection and remote device control are mainly realized by wired optical fiber. The chemical industry urgently needs low-latency, high-reliability wireless data transmission methods. In this context, this paper studies the functions of online monitoring, traceability and early warning, management, control and repair of an intelligent control system based on 5G+ edge computing capabilities in a chemical enterprises core equipment.

• Abstract ( 264 ) 　　
• For a long time, the design, manufacturing and optimization of data center server hardware has been completely dominated by server and chip manufacturers. The servers provided by manufacturers have a high degree of standardization and strong versatility, but they are difficult to deploy in some harsh on-site environments and are dealing with specific applications. When dealing with specific application loads, its service quality and cost performance cannot meet user needs. The customized servers can be designed and configured on-demand for software and hardware according to the on-site environment and application load characteristics. They can also show more excellent performance under specific business loads, and have gradually become an important development direction of the server market. In-depth research on the reasons for the rise of data center server customization, design configuration, and market applications will help the development of customized server technology and industry.
