摘要:
结合城市轨道交通的实际情况，对基于云平台的综合监控系统进行研究和方案设计。针对传统综合监控系统在系统资源使用、网络切换、数据同步等方面存在的不足，提出通过云平台的虚拟机迁移、故障HA(高可用)、存储双活和Oracle数据库同步等第三方的机制，简化应用软件，优化综合监控系统架构。根据云平台的技术特点实施主备数据中心实时服务器多重冗余；根据车站及控制中心实时服务器和数据库都集中在云平台上的特点，去除车站数据库，降低数据同步风险。基于云平台的的创新设计，极大地提升了综合监控系统的可用性和健壮性。
Abstracts:
Taking the actual situation of urban rail transit into consideration, an integrated supervision control system based on cloud platform was studied and the scheme was designed. Aiming at the shortcomings of traditional integrated supervision control system in aspects including system resource usage efficiency, network switching and data synchronization, third-party mechanisms such as virtual machine migration, fault high availability, storage dualactivity and Oracle data guard were proposed to simplify the application softwares and to optimize the integrated supervision control system architecture. According to the technology characteristics of cloud platform, multiredundancy of the real-time server of the main and backup data center was implemented. According to the characteristics that the realtime server and database of the station and the center are concentrated on the cloud platform, the station database is removed to reduce risks during data synchronization. The innovative design based on cloud platform significantly improves the feasibility and robustness of the integrated supervision control system.
