安卓系統無線伺服器設計及智慧型車輛的應用

Abstract

本論文為在Android系統上之車輛wifi伺服器系統的設計並實現智慧型車輛的應用。利用安卓開發板(CC-A80)作為車內伺服器(Server)，藉由權限帳戶管理來限制登入的裝置(Client)存取車內伺服器，除此之外，本研究甩開之前笨重的螢幕，達到每個人的智慧型裝置都是螢幕。每個登入的裝置可以同時觀看車內伺服器內的檔案，如：圖片, 音樂, 影片……等等，我們可以在車輛啟動的同時，透過USB連接OBD-II(On-Board Diagnostic OBD)模組獲取即時車資，而登入的裝置可以向車內伺服器獲取即時車況，並能藉由讀取故障碼，達到即時監控車輛是否發生故障，進而實現行車安全之監控。此外，透過Wifi Server Webcam即時影像機制，可以將Client的裝置變成一個即時行車影像的螢幕。 本論文建構了車用Client/Server架構，實現Client與Server間溝通基礎，Client除了可以向Server取得資料外，亦可控制Server做動作，例如播歌等功能。藉由本系統Client/Server Wifi Server架構，並於此架構上實作一些應用範例，實現智慧型車聯網系統。

In this thesis, the research implements a wifi server system for intelligent automobiles on android system. Use android development board (CC-A80) as the vehicle server. We limit the login devices by authorized account management rules. Besides, getting rid of heavy screen in the thesis and reach the goal of everybody’s device are screen. Every login devices can read the files in the vehicle server, such as images, music, videos…and so on. When starting the car, login devices can get the real time vehicle information from vehicle server by OBD (On-Board Diagnostic) connected with USB. And Reading the trouble code, we can monitor the car if the car is broken somewhere real time. Then, archieving the safety aim during driving, Besides, the client’s devices can be a real-time video of automobiles event with vehicle wifi server webcam real-time video mechanism. We build the vehicle Client/Server architecture in the thesis, archieving the communication base between client and server. In addition to getting some information from vehicle server, client also can control server to do some action, for example, playing music, etc. By means of Client/Server wifi server system, we implement some application based on this system then reach intelligent practical Internet of vehicle system.
