基于gRPC的城市轨道交通线网运营指挥平台分布式图纸数据同步更新方法

Synchronous update method of distributed drawing data for urban rail transit network operation command platform based on gRPC

针对城市轨道交通线网运营指挥平台(简称:线网运营指挥平台)图纸数据更新面临的业务数据量大、效率低,以及图纸一致性难以保障等问题,提出一种基于gRPC的分布式图纸数据同步更新方法。通过对线网运营指挥平台图纸数据更新业务流程的深入分析,设计了技术架构,并详细阐述了图纸分类存储、图纸更新服务、gRPC分布式图纸通信中心、多语言跨平台客户端及图纸更新集合识别等关键技术。实际应用表明,该方法实现了线网运营指挥平台多客户端集群下图纸版本同步更新与一致性保障,有效减少了人工维护图纸版本的工作量,提升了处理效率,为线网运营指挥平台大规模图纸同步更新提供了一种新的解决方案,也为网络化运营提供了重要技术支持。

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 indepth 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.
