數位化生活的時代已然來臨，各種分散式嵌入系統 (Distributed Embedded System) 已經普遍使用在日常生活中，也為我們帶來了許多便利性。 本論文主要為設計實現一電子化的車用物流系統，運用市場上傳輸速率較高的無線通信系統3.5G GSM (HSDPA) 做為通訊的介面，以目前廣泛使用的GPS做為衛星導航定位的介面，和RFID做為貨物追蹤定位的介面，內建30萬畫素數位攝影機監視物品狀況及SD Card儲存資料，再以內含多媒體解碼器的嵌入式系統加以結合，運用7吋LCD含Touch screen，挑選LED背光更為節能，方便物流駕駛員操作使用，提供DC 9～36V廣域輸入電源，以利各種型式的車輛來安裝，來做貨物追蹤、物流車輛派遣、位置掌控監視和即時影像回傳的研究與應用，也支援VGA、CVBS和LVDS輸出，以及在Barcode和RFID轉換初期，會需要較多周邊運用，也將增加UART埠到達6埠。 The digitizing life''s time has arrived. Each kind of distributed embedded system has been vastly used in the daily life. It also has brought more convenience for us. This paper mainly designs and realizes an automotive logistics computerization system. It utilizes interface that many kinds of wireless communication system to track freight, orientate and information response e.g. , 3.5G GSM(HSDPA), GPS and RFID. It integrates digital camera of 30K pixels to observe the goods condition. It has a SD card slot for storage. The multimedia decoder has integrated. It utilizes 7 inch LCD including touch screen and LED backlight to conserve more energy. It also support output interface e.g. VGA, CVBS and LVDS in order to display lucid operating condition. It will need many peripherals of UART interface in the initial period of the barcode transforms into the RFID. It may needs up to six UART ports.
