在安卓系統上之車輛物聯網系統的設計與實現

Abstract

本論文為在安卓系統上之車輛物聯網系統的設計與實現。本車輛物聯網系統包含六大功能，分別為行車紀錄器功能、檔案管理及播放功能、遠端監控功能、公路導航功能、車輛故障檢測功能及圖形化監控車輛功能。藉由將行車紀錄器與OBD-II(On-Board Diagnostic OBD)模組整合，我們可以在錄製行車影像與軌跡的同時，透過OBD-II模組獲取即時車況顯示於螢幕中，並將所獲得的車況資訊傳至遠端伺服器，進而實現行車安全之監控。另外本車輛物聯網系統中整合多項如車輛故障檢測、圖形化監控車輛以及導航功能，使駕駛能輕易了解車況且無須頻繁在各個不同系統裝置間轉換而易於操作，增進行車安全。 車輛物聯網系統與周邊裝置的連線設計是非常重要的，系統中的地圖資料必須經由網路存取Google Maps的圖資，而車輛的位置資訊必須藉由藍芽連接藍芽GPS模組取得。在硬體選擇上，為了更符合車用精神，捨棄一般市售的安卓平板手機，選擇發展空間較大的安卓開發板(CC-A80)做為實現平臺，並透過USB連接相機與觸控螢幕，完成車輛物聯網系統主體之硬體配置。

In this thesis, we implement an integrated and practical Internet of Vehicles System (IOVS). The IOVS includes event data recorder (EDR), file management, car remote monitoring, road navigation, car diagnostics, and instrument display in Torque application. By realizing EDR with OBD (On-Board Diagnostic) system, we can record the real-time information of cars, display them on the screen, and transfer the data to a remote server, which will improve the security of car driving. Besides, incorporating all the useful abovementioned features into one system, our IOVS provides the users a more straightforward method to understand the information of the vehicles, and enhances the driving safety. The communication between different devices in IOVS is very crucial. Hence, in IOVS, we can access the map information from Google Maps via the Internet and the detailed information of locations from GPS must be provided by the GPS Bluetooth module. For convenience, we choose the Android development board (CC-A80) as our hardware platform, instead of the common Android mobile devices. In addition, with great expandability, the extra camera and touch screen can be connected to the CC-A80 through the USB interface.
