| Summary: | ［Objective］ With the increasingly clear trend of network construction in urban rail transit, the line-level power dispatch system, as the core business of urban rail transit, is receiving more and more attention on its research and development. It is necessary to carry out an in-depth research on system software architecture, data interaction, cloud platform deployment, etc. ［Method］ A system software architecture in which applications and platforms are decoupled from each other is designed for the urban rail transit network-level power dispatching system. On this basis, key technologies such as database modeling technology, data subscription and publishing technology at the platform layer, network topology analysis and data sharding at the application layer are studied and discussed in detail. ［Result & Conclusion］ The decoupling of system software platform and application, as well as the adoption of related technologies such as standardized interface definition, data subscription and publishing technology, is beneficial for promoting the continuous expansion of the network-level power dispatching application analysis business in the later stages.The multi-node distributed real-time database adopts sharding technology, which on one hand makes it easier for the network-level power dispatching system to be containerized on the cloud platform, and on the other hand without interrupting business operations, solves the problem of continuous expanding real-time database capacity of the network-level power dispatching system with the construction of new lines. |
