This paper focuses on the main system architecture and disaster recovery scheme of the cloud computing platform for urban rail transit.It provides a detailed analysis of the advantages and disadvantages of various schemes from the aspects of safety and reliability,implementation difficulty,construction and operation cost,supporting facilities requirements as well as operation and maintenance management,and puts forward some reasonable suggestions for the networking scheme of the cloud computing platform for urban rail transit.Verification results show that the cloud computing platform for urban rail transit of two-level architecture features higher safety and reliability and has lower implementation difficulty during actual projects.However,external factors need to be considered for the system disaster recovery scheme,and a hierarchical deployment scheme should be adopted flexibly to maximize the advantages of various schemes.
