Currently,a new round of technological revolution and industrial transformation is thriving.As an important cornerstone of the fourth industrial revolution,the Industrial-Internet integrates new-generation information technologies such as Artificial Intelligence,Blockchain,Big Data,Cloud Edge Collaboration,Digital Twins,Edge Computing,and 5G.Through the construction of three functional systems of network,platform,and security,it realizes the full connection of all elements,all industry chains,and all value chains.Handle Identifier/Resolution Technology,as an important component of the Industrial-Internet,is also constantly exploring its application in different scenarios.At present,the application of the Industrial-Internet in the bridge construction industry is still in the exploratory stage of development,and is constantly exploring its application practices in the entire life cycle of bridges,supply chain management,upstream and downstream docking,and other aspects.This paper mainly describes the application exploration and research of identification analysis technology in connecting the data link from bridge construction to bridge monitoring and maintenance.
