发布时间：2019-03-19 09:30
【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]:Aiming at the problem of dual computer hot standby in coal mine safety monitoring system, this paper puts forward a software realization scheme, that is, using the trigger of SQL Server 2000 database to intercept the updated data of the database, and adopting the dual computer hot standby software to realize the data synchronization of the two computers. And through the man-machine interface to interact with the user; Aiming at the possible standby failure, database failure and software failure under this scheme, the corresponding solutions are put forward. The application results show that the implementation of the two-machine hot standby software has a good effect.
