摘要
介绍了如何定制一个适合变电站自动化设备中使用的嵌入式Linux系统。Linux是一个成熟的开放源码的现代操作系统,具有极好的硬件兼容性和软件可裁减性,适合应用在电力系统的变电站测控和通信等软件实时领域。一个实用的最小化Linux主要包括引导程序、初始化程序、设备文件、运行库以及在此基础上构建的用户应用程序,根据需要也可以加上适当的图形用户界面。给出了x86-PC体系下嵌入式Linux和MiniGUIWindows界面的构建过程,并对它们使用的GPL协议进行了解释。
To customize embedded Linux for substation automation equipment is introduced.Linux is a modern mature operating system with open source codes and suitable to real-time applications of measuring,control and communication in power system,which has better features of hardware compatibility and software flexibility.The smallest practical Linux system includes the boot loader,initialization programs ,device and lib files,based on which the user programs are built.The GUI (Graphical User Interface)may be added as an option.The construction procedures of Linux and MiniGUI on an X86-PC board are given and the GPL(GNU Public Licence)are explained.
