Building construction quality tracing method based on block chain

Abstract

The invention discloses a block chain-based building construction quality tracing method. A system is logically divided into a base layer, a core layer and an application layer; the base layer comprises an operation layer, an infrastructure layer and a data layer; the operation layer comprises a park engineering quality chain, engineering design, material supply and debugging and acceptance engineering construction sub-items; the infrastructure layer comprises hardware such as RFID, a material two-dimensional code, a temperature and humidity sensor, video monitoring and the like and BIM model software; the quality management data of the data layer is the summary of data acquired by the operation layer and the infrastructure layer; the core layer comprises a network layer, a consensus layer and a contract layer; the network layer is based on a P2P network, a propagation mechanism and a verification mechanism, and the consensus layer is based on POW, POS and DPOS consensus mechanisms; the contract layer comprises quality standards such as a quality acceptance specification, a quality specification and an intelligent contract. According to the method, a distributed architecture is adopted, decentralized data cannot be lost, meanwhile, tracing is easy in the using process in quality management, and information is more complete.

Description

technical field [0001] The invention relates to the field of smart construction sites, in particular to a blockchain-based construction quality traceability method. Background technique [0002] At present, there are many means of quality management in the engineering industry, which basically covers the whole process of quality data collection, management and application. However, the documents and materials generated at each stage of the construction project must be paperless and uploaded to the blockchain platform in chronological order. The authenticity and traceability of the documents cannot be guaranteed. Once there is a problem in a certain link, it cannot be traced back to the source. Responsible party. In the traditional engineering project management process, the engineering management contact form has problems such as long circulation time, many signing procedures, and difficulty in tracking progress in real time. SUMMARY OF THE INVENTION [0003] The purpose...

However, the documents and materials generated at each stage of the construction project must be paperless and uploaded to the blockchain platform in chronological order. There is no guarantee that the documents are true, effective and traceable. Once a problem occurs in a certain link, it cannot be traced upwards. Responsible party

In the traditional engineering project management process, the engineering management contact list has problems such as long circulation time, many signing procedures, and difficulty in real-time tracking progress.
