摘要

本論文主旨在整合現有技術以建立一套汽車黑盒子無線通信系統，將汽車行車資訊利用手機GPRS無線上網即時回報給伺服器，伺服器並會提供即時訊息給汽車駕駛人，以達成行車資訊共享之功能，目的在提供給汽車駕駛人更友善、更豐富的行車資訊界面，汽車駕駛人可利用黑盒子所提供的資訊以了解即時的車況以及即時的路況，有助於行車安全。本系統進一步更可以達到汽車防盜或交通事故發生後的責任釐清之功能。本文所討論的系統可分為四大部分，(1)汽車資訊擷取、(2)使用者顯示介面、(3)伺服器以及(4)用戶端歷史資料查詢。(1)汽車資訊擷取主要利用一個單晶片微電腦系統抓取GPS及OBDII之訊息，(2)使用者顯示介面利用PDA來顯示接收之訊息，(3)伺服器端主要為接收、儲存行車資訊以及提供汽車駕駛所需之訊息，(4)用戶端程式可以圖形介面顯示車輛儲存於伺服器之歷史資料。本文所建立的系統，可配合不同應用適當調整軟、硬體功能，因此具備多元化使用目的。本文詳細展示本系統設計的概念，並且實際測試來驗證本系統的可靠操作。

The main objective of this study is to create an automobile black box communication system by integrating current technologies. In order to share cars’ information with others, information of automobiles will be transmitted to a remote server by using GPRS of mobile phone. The remote server will reply with corresponding information to automobile driver. The purpose is to provide friendlier and more plentiful interface while driving. By using the proposed system, automobile driver can use information responded by the proposed system to know the real-time status of automobile and real-time traffic status to improve safety of driving. As a result, this system can guard car or to clarify the responsibility after a car accident.

There are four major components in the proposed system, (1) automobile information acquisition subsystem, (2) the user display interface, (3) the server, and (4) the client. The automobile information acquisition subsystem uses a single chip microcomputer board to retrieve information from the GPS and the OBDII. The user display interface uses a PDA to show information received. The server is used to receive and store information from automobiles and then response corresponding information back to automobiles. The client program can show the historical information that was stored in server. Experiments were conducted which demonstrated the capability of being a car information system. In addition, the proposed system can further be utilized for a variety of purposes regarding car information system.
