Research On The Safety Management System Of Metro Project Based On Blockchain Technology

With the expansion of urban scale and the rapid development of national economy,the problem of people’s travel congestion is becoming more and more serious,and the development of urban subway construction has become an inevitable choice.However,the subway project has the characteristics of complexity and hidden risks.Under the large-scale and high-speed construction environment,the subway project safety accidents occur frequently,and the subway project safety management is facing challenges.At present,the safety management of subway project is difficult to eliminate potential safety hazards from the source.Therefore,subway project safety is an urgent problem to be solved.Blockchain technology has been put on the national science and technology strategic plan because of its huge technology and application value.Therefore,this paper takes the subway project safety management as the research object,combined with the blockchain technology to build a new subway project safety management system,which has theoretical and practical significance.This paper has done an in-depth study on the safety management system of subway projects based on blockchain technology,and mainly carried out the following tasks:(1)By sorting out the relevant concepts and theories and analyzing the current situation,the compatibility of blockchain technology and subway project safety management is determined.On the basis of theoretical overview,this paper analyzes the multi-dimensional fit between blockchain technology and metro project safety management.(2)The safety management system of new metro project is constructed based on blockchain technology.Firstly,the idea of blockchain technology embedded in subway project safety management is clarified;Secondly,the safety management model is constructed and the process is explained from three dimensions of safety management participants,life cycle and smart contract.(3)This paper analyzes the safety management system of blockchain metro project.The advantages of blockchain embedded in subway project safety management are compared and analyzed;With the help of game model,this paper analyzes the safety and effectiveness of subway project safety management system based on blockchain technology,and explains the decision-making behavior of participating nodes in safety production under blockchain technology.This paper constructs a subway project safety management system based on the block chain technology and multi participants’ whole life cycle.Starting from the block chain technology principle,this paper puts forward solutions to the existing safety management problems of subway projects.This study is a preliminary exploration of blockchain technology in the field of subway project safety management,in order to provide new ideas for the follow-up blockchain research and promote the implementation of blockchain technology.
