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

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.
