基于“边缘计算云”服务的城轨车站综合监控系统降级方案

Degradation scheme of station integrated supervisory control system for urban rail transit based on edge computing cloud nodes

结合云平台在城市轨道交通的应用发展,对基于云平台综合监控系统降级方案进行研究和设计。针对传统综合监控系统车站实时服务器在中心云上部署后不能满足车站降级监控需求的情况,提出一种基于“边缘计算云”降级方案,并介绍降级服务资源需求、数据同步、控制权移交等内容。该方案既满足综合监控系统降级下的高可用性,同时又拓展车站就地“边”计算能力,为实施智慧车站创造更好的条件。

Combined with the application and development of cloud platforms in urban rail transit,a degradation scheme of integrated supervisory control based on cloud platform is researched and designed.Targeting cases where the traditional integrated supervisory control system for station with real-time server deployed on central cloud cannot meet the requirements while station entering degraded supervisory situations,a degradation scheme based on edge computing is proposed,and the degraded server resource requirements,data synchronization,and the rights of control transformation are introduced.It not only satisfies the high availability during the degradation situations,but also expands the on-site computing capability of the station,better adapt application of the smart station.
