Usb Port Dsp-based Data Analysis System And Realization

Under the background of national 863 project development of intelligent embedded instrument used for Big Mechatronical Equipment's Status Monitor and Trouble Diagnose, following the feature and requirements of signal process, this paper presents a realization of the real-time dynamic signal analysis system based on DSP(Digital Signal Process) ,USB(Universal Serial Bus) and EDA(Electronic Design Automation) technology, gives the details of hardware and software development. Specially, it describes the key technology USB communication.In chapter one, Introduces the research background of the thesis. The main content of the thesis is also listed in this chapter.In chapter two, the thesis mainly studies fundamental principles and technology of the signal analysis system based on DSP and USB. The technology include signal analysis, DSP,EDA and USB.In chapter three, Analyze deeply the main technique existed during giving the scheme, it is the USB driver design and chip interface design.In chapter four, the thesis specifies the system's hardware construction and realization, including the whole hardware framework, realization of the DSP-based module taking on data acquisition and signal processing, and realization of USB controller. Several involved technique problem are also discussed.In chapter five, the thesis detailedly describes design of USB communication and DSP software based on EZ-USB AN2131CHIP and TMS540VC33 DSP CHIP. Also give the details of driver design to realize the communication between Data Acquisition System and PC(Personal Computer).In chapter Six, summarization for this thesis is given, and research prospect in relative fields is also discussed.
