基于容器云技术的信号集中监测系统架构研究

Research on the Architecture of Centralized Signal Monitoring System Based on Container Cloud Technology

为提高信号集中监测系统的可靠性,降低系统的运维成本,提出一种基于虚拟化平台的容器云技术方案,对信号集中监测系统架构进行改造。将现有的服务器和存储资源进行虚拟化,并集成到云平台中,集中管理局、段、站的虚拟机、容器等资源。将原有的监测应用服务改造成独立的服务化应用,采用集群管理并部署在容器中。根据不同服务类型对改造过程进行细化拆分,逐个应用依次拆解改造,这种改造方式既可以保证原有系统的正常运行,又可以充分利用现有的物理资源逐步完成系统的容器化改造。改造后的信号集中监测云平台提供分布式集群服务、远程下载升级、测试集成、流水线交付等功能,并统一管理各个铁路局/段的服务,在云端统一操作部署、配置、升级、备份等,能够提高系统运行效率,降低运营维护成本。

To improve the reliability of the centralized signal monitoring system and reduce the operation and maintenance costs of the system,a technical solution of container cloud based on virtualization platform is proposed to modify the architecture of the centralized signal monitoring system.The basic idea is to virtualize the existing server and storage resources and integrate them into the cloud platform,which will centrally manage virtual machines,containers,and other resources of the railway bureaus,depots,and stations.The original monitoring application service is transformed into an independent service-oriented application,which adopts cluster-management and deploys it in containers.The transformation process can be gradually refined and split according to different service types,and each application can be dismantled and transformed one by one.This can not only ensure the normal operation of the original system,but also gradually complete the container transformation of the system,while fully utilizing the existing physical resources.The transformed centralized signal monitoring cloud platform provides distributed clusters service,remote download upgrades,test integration,pipeline delivery and other functions.The services of each bureau and depot are uniformly managed by the platform,and deployment,configuration,upgrades,backups,etc.can be uniformly operated in the cloud,improving system operation efficiency and reducing operation&maintenance costs.
