In recent years, industrial internet technology and manufacturing industry have continued to be deeply integrated in China, and the construction and application of the industrial internet identity resolution system has become a research hotspot. As a field related to the development of the national economy, this has important research significance. First, this paper compares the domestic and international mainstream identity resolution systems, and analyzes the design ideas of the industrial internet identity resolution system in China. Then, combined with the characteristics of the power equipment manufacturing industry identification in China, it explores an industry secondary node construction idea based on the Handle system, and proposes a set of Handle identity resolution system and technology implementation method suitable for the power equipment manufacturing industry. Finally, it explains the application value that the system brings to enterprises and the challenges and opportunities it will face in the future.
