嵌入式多媒体图象无线传输系统的设计

本系统由硬件和软件两部分组成，硬件部分采用Arm9 微处理器作为控制器，通过选
择合适外围芯片，实现了外围电路的扩展，视频采集模块为中星微摄像头，无线传输模块采用高速无线网卡，软件部分操作系统采用Microsoft公司的嵌入式系统WinCE，该操作系统采用模块化设计，简单实用。通过程序设计，实现对像头的开启，初始化，采集，关闭等控制操作，最后实现了图象的无线传输。

Embedded Multimedia Image Wireless Transmission System's Design Zhao Yinhao Zhang jing Dong wei (computer department of Shijiazhuang university Hebei shijiazhuang 050035)
Astract：This system is composed of hardware and software.Arm processor is used as the
controller of the system.By choosing proper chip,we design an embedded system.Acquiring
video device is VIMICRO camera,which is very popular on the market. Wireless transmission
device is wireless network card, the transmitting speed of which is 54M in no obstacle
environment. Operation system is Windows CE,which is Microsoft's production. It is designed based on many modules and very easy to use. The program running on the Arm board can open the camera, initialize it,acquire picture,close, so finally realized the image wireless transmission.
