可靠实现煤矿双机热备系统的方法

在分析商用双机热备系统在煤矿应用的局限性基础上,提出了一种适用于中小煤矿的双机热备系统纯软件实现方法。该方法采用单/双工混合运行模式保证双机实时性能和数据一致性,采用心跳线连接和对等网络消息传递机制实现运行故障监测与传递功能,采用数据自动同步技术减少人工干预和提高系统可维护性,并采用虚拟IP地址技术实现应用层透明访问和无缝切换功能。实验与应用案例证明该方法符合相关行业安全标准并具备现实可行性。

A Reliable Implementation Method of Dual-host Hot Standby System of Coal Mine

Based on limitation analysis of application of commercial dual-host hot standby systems in coal mine,the paper proposed an implementation method of software solution of dual-host hot standy(system) which is adapted to small-middle sized coal mines.The method uses simplex and duplex hybrid(operation) mode to ensure real-time performance and data consistency,heart-beat connection and peer to peer message delivery mechanism to detect and report system faults,automatic data synchronization(technology) to decrease artificial intervention and improve maintainability,and virtual IP addressing method to implement transparent access and seamless switching of application layer.The results of experiment and application showed that the method meets related industrial safety standards and is feasible.
