Dust Monitoring Information Management Based On Blockchain Technology

In recent years,there have been more and more dust-related companies in my country,and dust hazards have become the most serious problem in public health.According to statistical data,as of the end of 2018,occupational diseases caused by dust hazards in my country accounted for about 90% of the total occupational diseases,and dust explosions also occurred frequently.National regulatory authorities have strengthened the supervision and inspection of enterprise safety production management,and the inspection found that the current enterprise falsification of monitoring data and reports is the most prominent problem.In order to prevent enterprises from forging or tampering with monitoring data,this paper proposes a dust monitoring information management system based on blockchain technology.First,this article analyzes the application requirements of dust monitoring-related data management,and proposes to use hierarchical storage to realize the storage of dust monitoring-related data.Among them,enterprise employee information,monitoring equipment basic information,duty records,and other data with low security requirements are stored in a local database using traditional storage methods,which is convenient for enterprises to manage safe production.The monitoring data stored in the blockchain.The enterprise monitoring site and the supervision department are used as the blockchain system node to store and maintain the monitoring data.The decentralization and anti-tampering characteristics of the blockchain are used to ensure the authenticity of the monitoring data and realize supervision.Departments and enterprises share monitoring data to eliminate information islands.In addition,combined with the dust allowable concentration limit specified in the national occupational health standards,the monitoring data ranking and alarm function are realized in the form of smart contracts,and all functions are presented to the user through the operation interface,which facilitates the interaction between the operator and the system.
