Monitoring Scheme for Safety Hazard Status of Urban Rail Transit Operation Equipment and Facilities Based On Blockchain Technology

Urban rail transit plays a very important role in the social and economic development of cities. In order to ensure the safe and stable operation of urban rail transit operation equipment and facilities, it is necessary to monitor a large number of safety hazard status and data and improve the over-centralization of traditional monitoring. This paper designs a scheme for storing, validating, and monitoring the safety hazard status of urban rail transit operation equipment and facilities based on blockchain technology. The safety hazards of equipment and facilities during the operation stage of urban rail transit are listed using the literature analysis method and the case study method. The European RAMS(Reliability, Availability, Maintainability, and Safety) standard method is used to determine the safety hazard status of equipment and facilities by availability index. Based on the features of consensus mechanism, smart contract, and other features of blockchain technology, this paper designs an overall scheme for storing, verifying, and monitoring the safety hazard status of equipment and facilities. This scheme provides a practical operation method for evaluating the safety hazard status of rail transit equipment and facilities, which is conducive to the safety rectification of the entire urban rail transit
