基于B/S结构的高可靠性双机冗余架构设计
|
摘要
针对基于B/S结构的实时组态监控系统可靠性问题,提出一种新型双机冗余系统架构,在传统的双机冗余基础上,提出了被动式心跳检测方案,采用后台独立软件管理进程实现主备机切换控制,提高了实时组态监控系统的安全性和可靠性,延长了监控系统的非故障时间。
As to the problem of reliability of real-time configuration monitoring system based on B/S architecture,a new type of dual-redundant system architecture has been raised. Combining with the traditional dual-redundant architecture model,it puts forward passive heartbeat detection scheme,using backstage independent software management process to realize the switching control of host and spare machine,which improves the safety and reliability of real-time configuration monitoring system,extending the running time of monitoring system.
