| Summary: | 碩士 === 國立虎尾科技大學 === 車輛工程系碩士班 === 102 === Today, technologies change fast. It''s also happen on the vehicle diagnostic device. This paper describes how to make the vehicle diagnostic device easy to operate and more portable. The tip is to use the touch panel for the operation of the device and use Bluetooth by ISO 15765 Controller Area Network(CAN)to the way of communication.
This research uses F103RCT6 which belongs STM32 series for the control chip. In addition, the 3.2" TFT LCD touch panel is used to show messages and pictures and to operate various functions. Here are the two chief functions of this handheld device. One is to read basic messages of vehicles, and the other is to show the wrong messages of on-board diagnostics (OBD). The basic messages of vehicles include engine temperature, revolutions per minute(RPM) of engine and so on. Moreover, the wrong messages of OBD is showed by trouble codes with English explanations.
To be a handheld device, making it more portable and easy to operate are the points. Bluetooth makes messages easier and the touch panel makes the device portable. This handheld device feats drivers and engineers both.
