A blockchain database system for a rail transit equipment system

As of today, blockchain technology is virtually absent from rail transit applications, however, it has promising potential. For cloud-based systems or conventional systems, there too much information at the centre, resulting in a high level data processing. However, if processing capability can be provided edge station equipment, greatly reduces operation and maintenance pressure, same time, device takes form blockchain, possible to increase safety protection capability. It important reduce operating risks for metro equipment by installing fault diagnosis health management capabilities. This paper presents blockchain-based platform subway applications. The assistance includes design, construction, operation, assistance, energy saving manpower reduction fire linkage transfer stations, federal learning analysis artificial intelligence analysis, as well specific implementation plans implementing vent valve examples.
