Study On Traceability System Of Engineering Construction Quality Based On Blockchain Technology

Under the background of the new era of informationization,the construction industry,as a pillar industry of the national economy,should develop towards informationization and intelligence,give full play to the leading and supporting role of information technology,and create a new format for the construction industry.As a national strategy,the quality of construction engineering has become an inevitable development trend in the application of big data information in project quality management.How to use information technology to establish a new and efficient engineering quality information traceability system,and improve the real reliability of quality information data in engineering construction has become the focus of research.In recent years,the blockchain technology,which has been inadvertently modified and decentralized,has attracted worldwide attention and research as a set of distributed storage databases,and has played its subversive potential.Based on the analysis of the current status of engineering quality management,this paper proposes the purpose of engineering quality traceability.Then,according to the engineering construction process of the carding,the responsibilities and functions of the construction unit,design unit,construction unit,material supplier and construction supervision unit of the project construction participants were confirmed,and the construction,project and construction of the current project were carried out.The quality information data summarizes a set of feasible engineering construction information source systems,and divides the information sources of sub-projects in ten construction projects including foundation and foundation,main structure,and corresponding information source collection forms.Finally,the principle of blockchain technology is discussed and discussed.The mature Ethereum platform is selected as the blockchain underlying architecture,the geth as the development environment,and the B/S(Browser/Server)as the software architecture designed by the data layer.The business construction quality information traceability model consisting of the business logic layer and the presentation layer,and the function modules and implementation functions in the system are discussed in detail.At the same time,the application program is written and deployed to realize the entry,traceability and data of the construction quality information.The function of integrity verification.This study shows that the integration of new information technology blockchains has changed the traditional engineering construction quality traceability model.Applying blockchain technology to engineering construction quality information traceability can reduce the centralized centralization degree of traceability system for engineering construction management.Improve the all-round information,and improve the authenticity of the entire process quality information and data security,meet the requirements of dynamic management during the construction process,improve the efficiency of project quality management,and also solve the area Blockchain technology is difficult to land outside the financial industry.
