Abstract: The problems of conventional urban rail transit AFC (automatic fare collection) system such as many architecture levels and low resource utilization are briefly analyzed. Combined with cloud computing technology, an AFC system based on hybrid cloud platform is proposed, and the deployment mode, overall architecture and cloud platform architecture of the system is described in detail. The key technologies such as hybrid cloud dual active remote disaster recovery network-ing, hybrid cloud data storage architecture model, hybrid cloud resource scheduling are expounded in depth.
