  •   本論文應用嵌入式系統,透過第三代行動通訊(3G),設計並執行一套即時影像監視系統。這套系統是採用3G當中的CDMA2000 1X作為影像傳輸媒介,透過用戶端擷取影像資料,再傳輸至伺服端顯示。本系統主要分為兩部份,包括伺服端與用戶端。用戶端包含一台ARM-7嵌入式系統平台、一台CDMA2000數據機和一架網路攝影機。CDMA2000數據機用來撥接上CDMA2000網路,網路攝影機用來擷取影像,再以ARM-7核心的嵌入式系統來做為系統整合控制的平台,並連上具有固定IP位址的伺服站,執行影像擷取與傳輸的工作。本系統以影像傳輸的即時性能為目的做系統的設計執行並測試,其架構與元件,可配合監視目的做適當調整。

    A real time image surveillance system is designed and implemented in this thesis using an embedded system through the third generation (3G) mobile communication. It adopts CDMA2000 1X of 3G as the transmission medium of images. The image information is captured from a client and transmitted to the server for display. The proposed system is divided into the chief two parts of the server and the client. The client is composed of an embedded system platform, a CDMA2000 modem and a webcam. The CDMA2000 modem is used to dial up to the CDMA2000 network, the webcam is used to capture images. An ARM-7 embedded system integrates the system performance into a control platform to connect the information via Internet into the server on a fixed IP. The proposed system is designed, implemented and tested with real time performance for images. The framework and elements of the system in the proposed system can be modulated appropriately for the image surveillance purpose.
