小浪底大坝安全监测信息系统迁移的研究和实现

Migration of Xiaolangdi Dam Safety Monitoring Information System

大坝安全监测信息系统迁移是一项非常复杂的工作,系统迁移也是清理遗留问题的最佳时机。在对小浪底大坝安全监测系统迁移工作进行技术研究的基础上,通过采用组建虚拟专用网络、启用域控制模式、使用数据仓库复制技术和代理软件等方式,在保持原监测系统设备的部署位置和方式不变的情况下,完成了系统的迁移工作。

The migration of dam safety monitoring information system is a very complex task.It is also the best opportunity to clean up the legacy inefficiencies.Based on the researches on its technical problems,the migration of Xiaolangdi dam safety monitoring system has been successfully implemented by use of the virtual special network,domain control mode,database synchronization and proxy software,meanwhile,the deployment position and modes of the original system equipments have kept unchanged.
