Non-tampering Analysis And System Design Of Fire Network Monitoring Information Based On Block Chain

In recent years,fire safety has gained more and more attention from the society,as it becomes increasingly important as the result of urbanization.It is critical to ensure the normal operation of fire safety facilities and conduct proper daily maintenance.However,the current fire safety management is not satisfactory,as the maintenance is often relying solely on personnel investigation,without timely detection of potential safety hazards.Fortunately,with the advancement of Internet of Things technology,the intelligent fire safety monitoring platform is designed to monitor the operation of fire protection facilities in real time and achieve timely troubleshooting by fire safety personnel,apart from tracking the daily maintenance and management of equipment.For itself,the fire network monitoring system has a great demand for the data can not be tampered with and the data speed.This research aims to design a fire-fighting network monitoring system with block chain technology and DPoS consensus mechanism to ensure data security and prevent data tampering.The main work of this paper is as follows:(1)In view of the wide area and scattered facilities of fire control monitoring,it is proposed to deploy block chain nodes on the sensor of fire data acquisition,process the data collected by each node through block chain nodes,and all nodes form block chain system.The area establishes server separately,monitors block chain,obtains fire data,and provides system services to the outside world.The collected data of fire fighting facilities,such as water pressure of fire fighting pipe network,temperature of water in pump,smoke and temperature of network alarm,etc.(2)Combining the advantages of block chain and the actual situation of fire networking monitoring system,this paper uses block chain as the basic technical framework to communicate with local block chain nodes and call intelligent contracts to process the collected data and store them in the block chain system,thus realizing the decentralization of the system,distributed storage of data and preventing data from being tampered with.(3)According to the requirements of the fire network monitoring system,this paper designs the business organization structure of the system,and designs it in detail.(4)This paper adopts DPoS consensus mechanism to ensure the rapidity of system data,through the calculation of nodes to realize the choice of witness nodes,and realize the non-tampering of fire data.Finally,the block chain is validated and the results are in line with the expected goals.
