臺灣博碩士論文加值系統

1983 年 Bosch 公司所提出的 CAN Bus(Control Area Network) 通訊協定，在 1993 年列入 ISO11898 的國際標準。由於其高可靠度特性，有越來越多移動載具選擇使用 CAN Bus 來做各種交通工具內的重要通訊協定，例如: 汽車、火車、高鐵、船、飛機 ……等。甚至 CAN Bus 也在工業 4.0 扮演相當重要的角色。從診斷的角度看，一般 的小型車輛在 2008 年已將 OBDII 診斷接口作為車輛販售的必要條件，此接口內使 用的就是 CAN Bus 通訊標準。以往 OBDII 只使用於車輛的診斷，或者是單純 OBDII 的資料擷取後進行資料存取。本論文，預期延伸 CAN OBDII 的一般資料讀取應用 到可以透過 OBDII 對車輛進行控制。換句話說，希望透過具有 CAN Bus 通訊功能之 OBDII 診斷介面來對車內的電器控制單元 (Electrical Control Unit, ECU) 進行控制。基 於此想法，本論文設計一套橋接系統，此系統包含了四個子系統:1) 車內 CAN Bus 介 面系統，2) NB-IoT 通訊介面, 3) 雲端資料庫, 4) 人機介面 App。在車內 CAN Bus 介面 系統的部分，它可以將資料送達車內 CAN Bus 進行控制，NB-IOT 的通訊界面則是 負責接收雲端資料庫的資料，至於人機介面 App 可傳送控制指令到雲端資料庫。最 後，雲端資料庫則可以接收來自於 App 的資料，同時也可以將資料傳送至車內 CAN Bus 介面系統。本論文所設計之系統可以成功控制車上 ECU，如: 大燈、霧燈、方向 燈、警示喇叭、後車箱蓋、車門鎖，且經由測試之後無論在車輛行駛狀態下或者車 輛靜止狀態下都可以成功控制。基於本論文所提出之系統，未來可對以下之產業進 行加值服務: 車輛租賃、共享車輛、車輛改裝、CAN Bus 相關應用之產品或載具。

The CAN Bus (Control Area Network) communication truck proposed by Bosch in 1983 was the international standard of ISO11898 at the end of 1993. Due to its high reliability characteristics, more and more mobile vehicles use CAN Bus for important communications and aviation in various vehicles, such as automobiles, trains, high-speed rails, ships, airplanes, etc. Even CAN Bus plays a very important role in Industry 4.0.
From the perspective of diagnosis, ordinary small vehicles have adopted the OBDII diagnostic interface as a necessary condition for vehicle sales in 2008, and the CAN Bus communication standard is used in this interface. In the past, OBDII was only used for vehicle diagnosis, or simply OBDII data was retrieved for data access. In this paper, we hope to extend the general data reading application of CAN OBDII to control the vehicle through OBDII. That is, it is hoped to control the electrical control unit (ECU) in the car through the OBDII diagnostic interface with CAN Bus communication function.
Based on this idea, this thesis designs a bridge system. This system includes four subsystems: 1) CAN Bus interface system in the car, 2) NB-IoT communication interface, 3) Cloud database, 4) Human-machine interface App. In the CAN Bus interface system in the car, it can send data to the CAN Bus in the car for control. The communication interface of NB-IOT is responsible for receiving data from the cloud database. As for the man-machine interface App, it can send control commands to the cloud data. Library. Finally, the cloud database can receive data from the App, and can also send the data to the CAN Bus interface system in the car.
Through the system designed in this thesis we can successfully control the ECUs on the car, such as headlights, fog lights, turn signals, warning horns, trunk lids and door locks. We have carryed out the above ECUs control testing. The results show that the ECUs can be controlled when the vehicle is running or in stationary. Based on the system proposed in this thesis, value-added services can be provided to the following industries in the future: vehicle rental, shared vehicles, vehicle modification, products or vehicles related to CAN Bus applications.
