Design And Implementation Of Automobile Fault Monitoring System Based On WINCE

Embedded system as a new embedded system has been paid high attention in every field at present. Embedded system gradually replacing the simple single chip microcomputer system has become a trend, and is used widely in the Automotive Field.This paper develops a new type of fault detection and diagnosis system of the automobile engine, this hardware of this system adopt the popular kernel ARM9 at present, improving the speed of system, the software adopt the popular operating system WINCE, it has friendly user interface and can be easily operated.This article Firstly study the advantage of Embedded system applying in the automobile fault monitoring system and the safety applicability, then choose and construct the proper software and hardware support platform, including the hardware structure of the CAN controller, the Windows CE.NET4.2 embedded operate system and the Visual Studio.NET 2003 Integrated Development Environment and so on.Secondly, designing the upper software system of the automobile fault monitoring based on the actual requirement of the automobile fault monitoring. Including the CAN bus communi_ cation module, the customization process of WINCE operate system, the database module and implementation of the upper business logic.This system consists of data collection module, data display and alarm module and the data query module. If there are some abnormal signs of tires, the system will send alarm to driver to take measures, so the possibility of traffic accidents will be the least.In the end, summarize the study work of this thesis, and put forward some advice and Prospect of the further research and develop of this system.
