The Design And Application Of Monitoring System Based On ARM9 And Embedded Linux

With the increasing importance of embedded technology, the development of embedded systems for all to see in recent years, embedded system applications increasingly broad. Whether in traditional industrial monitoring, mechanical control, or the emerging mobile communications, digital entertainment, embedded systems are gradually moved into all aspects of production and lives of the people. In the industrial testing, the traditional embedded control systems primarily for the single-chip microcomputer hardware vector design, function relatively single, visualization, and limited scalability. With the Linux system constantly upgrading and updating, and now appeared to ARM chip carrier and Linux systems software platform designed for a new generation of monitoring system. In addition to achieving the original microcontroller functions, visualization stronger, equipped with the network communication function is a function of developing a more abundant micro-computer .This paper,based on ARM9 experimental platform provided by the Wuhan ChuangWeiTe Information Technology Co. Ltd., designs a monitoring system to conduct research and application. System platform is Linux2.4.18 kernel, GUI for the first time in the bottom Qt graphics module, using C + + and Qt graphical user interface library monitor the development of graphical data integration platform. This article first start with the hardware platform design, based on demand for cutting circuit, the hardware circuit design schematics, design chapter in the software system Linux operating system platform, how to build a development environment, and were on the A/D conversion, CAN Bus drivers Procedures and application programming, the final details in Qt, how to use C + + language designed monitoring system graphical interface, the software design process for clues on the object to the programming model, pop-up dialog design, with Read a memory function in excel form design, drawing and graphics of how to call C language program graphical interface, the driver of the call, in order to achieve real-time display, showing the effect of the system is running, and made improvements and The development board features expand the idea of upgrading. As an application of research papers, the paper mainly on the software design, while the diagnosis and monitoring technology, provides a similar software design and development of the reference model, the study proved to be effective and real-time.
