摘　　要：针对当前变电站信息化建设的需要,作者提出了一种基于SCADA(Supervision ControlAnd Data Acquisition)系统的小型变电站无人值守远程监控方案.重点在数据库服务器的软件.在该系统的开发过程中,采用了当前软件开发中流行的设计模式的思想.其中的组成模式旨在加强模块间的联系和模块操作的一致性;策略模式实现了多种访问行为的统一对外接口.这两种设计模式的使用加强了系统的健壮性、可扩展性和效率.According to the need of information constructing in transformer substation, a remote unattended monitoring scheme based on SCADA was proposed. This paper focuses on the software on database server. During the development of this system, the design patterns, a fashion in current software developing is applicated. Composite strengthened the correlation of modules and consistency of module manipulation; Strategy realizing uniform interface of multiform accessing behavior. The application of these two design patterns reinforced the robust, extensibility and efficiency of the system.
