摘　　要：实时数据库是工业变电站监控软件重要的组成部分,用以管理整个监控系统的实时数据。根据工业变电站要求和实时数据库的特点,给出一种基于VC++6.0的实时数据库设计方法,利用动态链接库(DDL)技术建立了实时数据库,并介绍了历史数据的存储。经现场联网调试证明其性能良好,能够满足工业变电站实时监控的需要。Real-time database is the important component of industry substation monitoring software,which is used to manage the entire monitoring system. According to the characteristics of industry transformer station and real-time database, a kind of realtime database designing method based on VC＋＋6.0 is provided.Real-time database is established through using the technology of dynamic link library （DDL）, and the storage of historical data is introduced. Its performance is proved on the field network debugging, and it can meet the needs of industrial transformer substation real-time monitoring.
