Abstract: 隨著汽車產業的電腦化以及無線通訊技術的發達,同時結合資訊與通訊技術稱之為車用資訊通訊系統(Telematics)。其功能以導航及獲得即時車輛資訊為主,期望達到增加駕駛人的便利與運輸系統的效率之目標。 此研究所建立的雛形系統是利用J2ME在行動電話上開發,提供駕駛人利用行動電話、車用電腦透過GPRS上網向監控中心提出擷取自身所駕駛車輛或他人所駕駛車輛資料之請求,此時車用電腦以雙模式自適性切換為基礎取得由感測裝置上所收集到的資料傳送至監控中心,獲得即時車輛、路況資訊,監控中心再利用Socket通訊協定把資料回傳給使用者。監控中心與使用者必須事先共同協議資料傳輸格式才可進行傳輸,進而將資料轉換成車牌、車速、位置、狀態、溫度等資訊顯示在行動電話上供使用者參考,達到即時車輛監控派遣與安全管理。 本研究確實實作一套對於駕駛人或車隊的管理者皆適用的整合車輛資訊系統,透過地圖及線上車輛訊息做即時的車輛監控,以即時傳達到需要資訊人士的手裡、即時掌控最新資訊,進而提高效率,降低電話連絡之通訊成本。
As the computer and wireless communication technologies have greatly advance, Telematics, which stands for the integrated use of telecommunications and informatics, has got more and more attention recently. In particular, the application of the navigation technologies and the real-time vehicle information can bring the driver much convenience and can also promote the efficiency of a transport system. In this study, we develop the communication structure of cellular phones, car-PCs and the monitoring center communication. A car-PC will automatically and periodically collect data from the sensors installed on the car and then send the data to the monitoring center via wireless communication channel. Therefore, the monitoring center can grasp real-time information about the vehicles, situation on the roads, and so on. We use J2ME to develop a system on the cellular phone so that a driver can use a cellular phone to request the monitoring center for getting vehicle information via GPRS. Also, the monitoring center can automatically deliver information to the driver’s cellular phone. The monitoring center, the cellular phones and the car-PCS have a common data format and communication protocols so that the data can be transformed to useful information for the drivers, such as the car license number, the vehicle speed, position, status, and temperature, etc. All the information will be shown on the cellular phone. Thus, the goal of real-time vehicles monitoring, dispatch and safety control can be achieved. The integrated platform that we have developed in this study can further integrate electronics map to provide more convenient and efficient real-time vehicle supervision and management.
