執行起迄:2019/08/01~2020/07/31
總核定金額:766,000元
中文摘要:隨著雲端網路資訊整合智慧科技逐漸成為全球化產業的趨勢,而智慧交通除了提供精確的地圖導航資訊之外就是道路狀況的即時更新與資訊收集,目前Google地圖雖然可以提供方便的交通導航地理資訊,但僅是2D的地圖資訊,缺少道路水平高度及坡度資訊,因此如果能增強目前的交通地理資訊,進而提供完整3D的道路交通地理資訊,對於行車道路規劃及智慧城市交通將更有效益,本計畫之目標即是完成一光學式動態路況掃描系統,利用車載光纖陀螺儀達到車輛行進仰/傾角度的動態感知能力,當車輛行進時上坡或下坡時,由於桑納效應(Sagnac Effect)造成光纖陀螺儀內正/反兩道光束的相位差的干涉,藉由干涉強度得知車輛行進角速度的變化,同時將光纖陀螺儀的角速度角信號藉由無線ZigBee傳輸至遠端再與GPS及車速資訊整合分析得到道路坡度變化的資訊。本套車載光纖陀螺儀及信號解調系統除了可以提供3D道路地理資訊資料庫之外亦可以利用行駛的高頻訊號檢測道路施工品質如路面地平整度,孔蓋數目,有效提升道路的施工品質數量化之參考。
英文摘要:With the cloud intelligent information network has gradually become the base of global economy, it is necessary of providing accurate and real time road map navigation information for modernized city traffic construction. Although Google Maps are able to provide convenient traffic navigation and geographic information, but only 2D map information is a lack of detailed road information. Therefore it is more effective to enhance the current traffic and geographic information system by providing a complete 3D road traffic geographic information for traffic navigation and intelligent urban geographic planning. This project has completed a high efficiency optical pavement incline scanning device, using a vehicle-mounted low speed opticl fiber gyroscope circuit which can detect the inclination angle of a driving vehicle. In addition, by applying wireless transmission technology such as ZigBee to broadcast the detected signal to a remote data processing unit and combined with the carrier traveling speed and GPS positioning information to achieve 3D road inclination information. It can be used as an accurate measurement for pavement quality for trafic naigation and the geographical planning for the development of a modern city.
