| 摘 要： | 针对煤矿瓦斯灾害预警系统软硬件运行环境的单点失效问题,设计了一种基于双机热备的瓦斯灾害预警系统,介绍了该系统的双机热备方案、软硬件结构设计及实现方法。该系统选用互备运行模式的双机备份高可用性集群及基于RoseHA和共享磁盘阵列的双机热备方案,提高了系统的可靠性。应用结果表明,与单服务器的预警系统相比,基于双机热备的瓦斯灾害预警系统的平均无故障间隔时间大幅增加,平均故障修复时间大大缩短,系统可用性有了较大提高。

Design and implementation of gas disaster early-warning system based on hot-standby |
| |
| Abstract: | In view of problem of single-point failure in hardware and software running environment of gas disaster early-warning system of coal mine,a gas disaster early-warning system based on hot-standby was proposed,and its hot-standby solution,hardware and software design and implementation were introduced.The system employs high-reliability hot-standby cluster for mutual backup and hot-standby solution based on RoseHA and shared disc array,greatly improves its reliability.The application result shows that availability of the gas disaster early-warning system based on hot-standby is greatly improved with longer mean time between failures and shorter mean time for fixing failure,compared with the early-warning system based on single server. |
