本論文主要在研製一套通用型即時車況警示系統,以OBDII協定作為媒介,蒐集車輛即時行車數據,搭配GPS、4G/IOT以向雲端回報位置、即時狀態與照片。 內容主要分為五部分,第一部分主要說明動機與研究目的,第二部分介紹OBD-II通訊協定,第三部分講解系統架構與使用的硬體,第四部分為系統開發,完成硬體並測試能否上傳至雲端,第五部分是結論,探討成本與再開發性。
This thesis is mainly to develop a universal real-time vehicle condition warning system, the system uses On-Board Diagnostic II (OBD-II) agreement as the medium, collect real-time driving data of vehicles, report location, real-time status, photos and GPS data to the cloud via 4G/IOT. Thesis is mainly divided into five part, the first part is the introduction to illustrate motivation and research purpose. The second part introduces the OBD-II communication protocol. The third part explains the system architecture and the hardware used. The fourth part is system development, completed the hardware, and checked the correctness of the data on the cloud. The fifth part is the conclusion, discussed cost and possibility of redevelopment.
