Campus Fire Management Model Based On Private Blockchain

Recently,because of the large number of students,the large density of the personnel and the imperfection of the fire management system,the campus fire accidents occur frequently in various colleges and universities in China.But colleges and universities are not implemented in accordance with the Regulation of fire safety management in Institutions of higher learning.The main reasons are the following three points.Firstly,the trusting relationship among the various departments in colleges and universities are weak because of the great responsibility of fire safety management.For example,there is a great relationship between the failure of the main responsibility of the second-level units and the lack of trust in the supervision and control of the fire department.Secondly,the data of the second-level units are not connected and interconnected,which leads to the formation of data island in the fire fighting work of various departments,and it is hard to play a full role.Thirdly,there is not a fast and effective supervision mode between the second-level departments and the fire protection departments in colleges and universities,and the fire reliability of various second-level units is not high enough.So the campus fire cannot be effectively forewarned.In view of the above problems,this paper proposes a new Campus Fire Management Model based on Private Blockchain(CFMM-PBC),which uses a private blockchain architecture to generate and store various firefighting data,providing fire safety data that cannot be tampered with for fire protection departments in colleges and universities,and the information can be traced back all the time.Besides,we design a new fire data storage structure based on Merkle Patricia Tree(MPT)according the demand of high efficient management,which improves the lookup efficiency of CFMM-PBC and ensures the accuracy of query results.Moreover,we revised design the block generation protocol,consistency protocol,the view switch request and strategy and the timeout garbage collection mechanism,which improves the consensus efficiency of the consensus mechanism and solves the trusting relationship among different departments in the CFMM-PBC.This paper built a private block chain based on the above models,which are applied to the fire safety management.The experiments show that the improved method could achieve low communication overhead,meet the delay and throughput requirements of block generation,and support millisecond query time.Beside,CFMM-PBC can achieve strong trust,data interaction,mutual trust and supervision among departments.Thus,the related problems are solved.For the dynamic supervision of the superior departments,there is still a further improvement in the management model.
