The Software Design And Realization Of The Fuel-cell Vehicle Onboard Integrated Information Platform Based On MiniGUI

The onboard integrated information platform is the expansion of the dashboard system function and the information exchange window between the automobile and driver,is also a key component of the high-tech vehicle.At the same time,with an excellent graphical user interface,usinghigh-reliability,high-controlled and high-speed features of the modern MCU to gather,display,monitor and record the vehicle inside of the sensor.Consequently,the driver and the staff engaged in the vehicle research comprehend the work status of the various components inside the vehicle conveniently and alternate friendly and reliably.Thus,the development work has become very urgent requirements.The software system requirements of the onboard integrated information platform is analyzed and the process of the software design and realization is developed by the thesis.The hardware platform currently adopt the popular ARM system to enhance the expansibility of the system function,the system integration and advance the system,using embedded operating systemμClinux and graphical user interface MiniGUI design the system applications at the same time to improve the real-time and stability of the system.The hardware structure of the system onboard integrated information platform is introduced briefly,which constitutes with these equipment components of the ARM7 microprocessor S3C44BOX,the MCP2510 CAN controller and the USB controller SL811HS and contrapose the hardware platform to develop the underlying drivers based onμClinux,including mouse driver,keyboard input procedures and graphics driver.The software system of the onboard integrated information platform is studied and designed in the thesis.Firstly,the characteristics and structure ofμClinux and MiniGUI is analyzed by the thesis,then make use of MiniGUI to develop the application procedure of the onboard integrated information platform and explain the design idea at the same time,make cross compile aim to the hardware platform dominated by the chip S3C44BOX and design corresponding system boot procedure bootloader.Finally,the transplant to the ARM7 plank has achieved in the thesis successfully.The built-in linux system from the angle of product structure has been adopted in the thesis,and applying the method that using MiniGUI compile interface to quicken the design development,the onboard integrated infomiation platform designed by the thesis has good real-time and stability through the laboratory tests.
