煤矿安全监控系统双机热备软件实现方案

Software realization scheme for hot standby of coal mine safety monitoring and control system

  • 摘要: 针对煤矿安全监控系统的双机热备问题,提出了一种软件实现方案,即利用SQL Server 2000数据库的触发器拦截数据库更新的数据,采用双机热备软件实现数据双机同步,并通过人机界面与用户交互;针对该方案下可能出现的备机故障、数据库故障以及软件故障,提出了相应的解决方案。应用结果表明,该双机热备软件实现方案效果良好。

     

    Abstract: For hot standby problem of coal mine safety monitoring and control system, a software realization scheme was proposed, namely using trigger of SQL Server 2000 database to intercept updated data in the database, using hot standby software to realize data synchronization, and designing human-machine interaction interface. For standby computer fault, database fault or software fault in the schema, corresponding solutions were proposed. The application result shows the scheme has good effect.
