本系統(tǒng)由硬件和軟件兩部分組成，硬件部分采用Arm9 微處理器作為控制器，通過選
擇合適外圍芯片，實現(xiàn)了外圍電路的擴展，視頻采集模塊為中星微攝像頭，無線傳輸模塊采用高速無線網(wǎng)卡，軟件部分操作系統(tǒng)采用Microsoft公司的嵌入式系統(tǒng)WinCE，該操作系統(tǒng)采用模塊化設(shè)計，簡單實用。通過程序設(shè)計，實現(xiàn)對像頭的開啟，初始化，采集，關(guān)閉等控制操作，最后實現(xiàn)了圖象的無線傳輸。

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.
Key words：Video Acquiring , Embeded system ,WinCE,Arm9
