Every auto part can be identified in the industrial Internet environment and become a member of the Internet of Everything scene. The complete industrial service system in China's industrial Internet application is also being gradually built through the international root node, national top node, secondary node, enterprise node and recursive node in the industrial Internet identity resolution system.
In the guidelines for the construction of secondary nodes of industrial Internet identity resolution formulated by the Industrial Internet Industry Alliance, a hierarchical structure has been defined for the industrial Internet identity resolution system, which has become the industry consensus. Specifically, it includes three parts: identification coding, parsing system and data service. Among them, the identification code is a global "ID card" that gives physical resources such as machines, products, components and virtual resources such as algorithms, processes and data information in the industrial Internet. As the core infrastructure to ensure the orderly operation of the global industrial Internet, the identity resolution system is similar to the Internet Domain Name System (DNS), but it is not only for querying information, but also for sharing and sharing data across enterprises, industries and regions, and promoting the digital transformation of manufacturing industry, especially auto parts.
In order to encourage the full penetration of industrial Internet into all walks of life, since 2017, governments at all levels led by the Ministry of Industry and Information Technology have successively issued a series of guiding policies, opening the system construction of the infrastructure of the identification analysis system and the cultivation and promotion of industrial applications. Up to now, the five national top nodes in Beijing, Shanghai, Wuhan, Chongqing and Guangzhou have continued to operate stably, and the two major standby nodes in Nanjing and Chengdu have continued to be built. There are 203 online secondary nodes nationwide, covering 29 provinces (autonomous regions and municipalities directly under the Central Government), 34 industries, 142795 access enterprise nodes in total, 150.6 billion logo registrations, 124 million daily average resolution of top nodes, and 7.57 million active logo carriers deployed.
With the initial formation of the hierarchical structure of the industrial Internet identity resolution system, the industry consensus is also gradually expanding, and a collaborative ecosystem and a multi-level supplier system of "end, edge, network and source" oriented to the four major sectors of industrial foundation, key systems, integrated applications and support services have been established. In just three years, the scale effect has emerged - the total number of industrial Internet logo registrations in 2021 is 38 times that in 2019, and the total number of logo resolution is 860 times that in 2019.
