摘　　要：实时数据库是嵌入式系统的核心,用来定义数据变量,负责与外部设备进行实时数据交换。在用组态软件开发嵌入式应用时,在开发环境中定义实时数据库结构、数据来源及类型,在嵌入式运行环境获取实时数据库的数据,并进行显示、报警、存盘等操作。着重介绍了基于Linux的嵌入式组态软件中实时数据库的设计及其实现。Real-time database, an important part of embedded system, is used to define variables to receive data from hardware. The Structures of the database, source and type of the variables are defined in development environment in configuration software,the realtime data in database, which is obtained from hardware in running environment,can be displayed, alarmed and saved. In this paper, how to design and realize real-time database of the Linux-based Embedded Graphic Configuration Software （LEGCS） is emphasized. In addition, part of source codes is given.
