Embedded System Applications, Power Communications Server

The paper discussed a computer system about the research of power communication server based on embedded Linux.The development project is part of the last project of China HuanDian Group Power Transmission & Distribution Corporation.It is necessary to design an embedded GUI.The GUI can be used to simplify the development of power communication server and improve the system flexibility.The paper dealt with the development of power communication server. The project opened up broad possibilities for the use of ARM9 hardware and the use of Linux OS for software programming environment. The paper effectively grappled with problems of communication protocol and the human-computer interface to make power communication sever more competitive.During the course of development, the main works that the paper discussed as follow: To determine the functions of power communication server and the functions of GUI for users.It was based on the leading echnology.It was for the purpose to satisfy thecustomer's requirement. The development technology of embedded Linux had been used extensively during the project. Analyze and realize the communication protocols-CDT protocol,the operation of embedded DB to deal with the data of power ,use MiniGUI to design a GUI systerm for users.
