Car Monitoring And Diagnosis To The Gui Design And Implementation

As the development of the embedded technology and the increasing expansion of the embedded system's application scope, the traditional character interface and the simple graphical interface cannot satisfy the users'requirement. The demand to lightweight GUI (Graphic User Interface) is getting more and more urgent. Embedded GUI is an important component of the man-machine interaction technology, which is used by more and more embedded systems and also becomes one focus of the embedded technical applied research domain by its rich graph information, direct-viewingly convenient operation and so on.The on-board monitor and fault diagnosis GUI system is the vehicle maintenance support equipment, which records and displays some parameters and fault information of automobile in running by embedded GUI and embedded equipments.This paper mainly introduced a kind of design and implement method how on-board monitor and fault diagnosis GUI runs on the software platform of Linux and graphical interface system based on MiniGUI. Also, the application software of detection and diagnosis on this hardware platform has been realized. The hardware platform is consisted of S3C2440A processor, external storage equipment, LCD, touch screen, kinds of interfaces and the assistance circuit for power supply system, clock system and system debugging. The hardware platform can completely satisfy the request of on-board fault diagnosis system based on the results of experiments. The software design mainly includes the transplantating of Bootloader and Linux core, the design and development of on-board monitor and fault diagnosis GUI system based on the MiniGUI 1.3.3 graphical user interface support system. The system can display various information of automobile and carry out human-computer interaction.
