Research On Blockchain-based Road,Bridge And Tunnel Informatization Method

In order to solve the frequent problems of jerry-building and opaque construction information in the construction process of road,bridge and tunnel projects,strengthen the quality control of raw materials of road,bridge and tunnel projects,and improve the control of road,bridge and tunnel project information,this thesis,based on the existing blockchain security information management methods at home and abroad,combined with the traditional road,bridge and tunnel project information management scheme,i n-depth study of blockchain technology,through smart contract technology to achieve road,bridge and tunnel project digital management of information.The main work of th e thesis is as follows:Firstly,this thesis constructs a blockchain operating enviro nment based on FISCO BCOS,reconstructs the execution architecture and hierarchical architecture of the consortium chain,and improves the traditional PBFT consensus algorithm according to the raw material information flow requirements and raw material information sharing requirements in the information management of road and bridge tunnel projects.It proposes the TLGT-PBFT consensus algorithm,which effectively reduces the consensus delay and provides a basis for the design and implementation of the data exchange model.Secondly,aiming at the information security storage requirements in the information management of road and bridge tunnel projects,this thesis designs a blockchain data exchange model based on the TLGT-PBFT consensus model and the alliance chain execution architecture.This model uses smart contract technology to realize the information traceability of road and bridge tunnel projects from raw material manufacturing to construction and raw material information sharing between projects.Finally,this thesis tests the blockchain data exchange model based on TLGT-PBFT from three aspects: security,applicability and efficiency.In security testing,compilation tools,including Mythril,were used several times.In the applicability test,all aspects of the model functions were tested for completeness.In the performance test,a pressure test was carried out on the intelligent contract interface used by the core functions.The test results show that compared with the traditional PBFT and GBFT,the proposed model using the TLGT-PBFT consensus algorithm has a similar error rate,and the performance is improved by about 11%compared with GBFT.The three test results prove that the model can not only effectively guarantee the safety and applicability of road,bridge and tunnel engineering information,but also has good performance.It has certain application value for the research of road,bridge and tunnel engineering information management,and provides exploration and practice for the implementation of blockchain technology in the field of road,bridge and tunnel engineering information management.
