Building multiple-supply-chain coordination system based on blockchain and BIM model, and method thereof

Abstract

For settling problems such as liability and obligation risk distribution indeterminacy, intellectual property ownership disputing and easy leakage of shared secret information in building informationmodel BIM technology in prior art, the invention provides a building multiple-supply-chain coordination system based on blockchain and a BIM model, and a method thereof. Through combining characteristics of decentralization and unchangeable record in blockchain technology and advantages of high integration degree and platform sharing in the BIM model, the building multiple-supply-chain coordination system which has advantages of stronger function, higher information safety and wider application is constructed. The building multiple-supply-chain coordination system based on the blockchain and the BIM model mainly comprises a technological layer, a data layer, a model layer, an interaction layer, an application layer and a user layer.

Description

technical field [0001] The present invention relates to the technical fields of building information models, computer networks, computer security, and computer authentication, and in particular to the technical field of computer security and collaborative operation of block chains and BIM models. Background technique [0002] In the modern construction industry, BIM (Building Information Modeling) is used more and more widely. BIM technology is based on the relevant data of the construction project, simulates the real information of the building through digital information, and realizes project supervision, property management, equipment management, digital processing, engineering management, etc. through the three-dimensional building model. Features. It has the characteristics of information completeness, information relevance, information consistency, visualization, coordination, simulation, optimization and graphing. Through the building information model BIM, the cons...

Problems solved by technology

[0005] In order to solve the problems existing in the existing BIM technology, such as ambiguous distribution of responsibility, obligation and risk, disputes over the ownership of intellectual property rights, and easy leakage of shared confidential information, this invention proposes a multi-supply chain coordination system for buildings based on blockchain and BIM models. And its method, by combining the characteristics of decentralization and immutable records of blockchain technology, as well as the advantages of high integration and platform sharing of BIM model, to build a more powerful, more secure information, and more widely used architectural data supply chain coordination system
