Design and realization of information exchange platform based on embedded terminal
基于嵌入式终端的信息交互平台的设计与实现

In view of embedded device's features,and with the practical research into the information exchange for building numeric campus,a new design of information exchange platform based on embedded terminal was proposed.Through constructing model of the platform and analyzing architecture of its primary embedded terminal,the realization of message exchange and data upload with mobile phone was described,which took Linux as the operating system and Intel XScale PXA270 as the core of hardware,as well as employed an expanded module for mobile communication.Finally one of its examples was given to illustrate the detailed process which was used for information exchange within different subareas of a campus.
