Synchronous update method of distributed drawing data for urban rail transit network operation command platform based on gRPC
This paper proposed a distributed drawing data synchronization update method based on gRPC to address the problems faced by the urban rail transit network operation command platform in updating drawing data,such as large business data volume,low efficiency,and difficulty in ensuring drawing consistency.The paper conducted an in-depth analysis of the business process of updating drawing data on the operation command platform,designed a technical architecture,and elaborated on key technologies such as drawing classification storage,drawing update services,gRPC distributed drawing communication center,multilingual cross platform client,and drawing update integration recognition.Practical application shows that this method implements synchronous updating and consistency assurance of drawing versions in a multi-client cluster of the operation command platform,effectively reduces the workload of manual maintenance of drawing versions,improving processing efficiency,and provides a new solution for large-scale drawing synchronous updates of the operation command platform.It also provides important technical support for networked operations.
