Research And Implementation Of Ethernet-based Real-time Signal Analysis System

The signal analysis system is coming in a great change in Internet age. This paper presents a realization of the real-time dynamic signal analysis system based on Ethernet both in software and hardware. Through using DSP, embedded RTOS and reasonable task-assigned strategy, it ensures the system's demand for real time and data transmission speed of network.In chapter one. the thesis expounds the recent developments in signal analysis system and relative techniques, and introduces the research background of the thesis. The main content of the thesis is also given in this chapter.In chapter two, the thesis mainly studies fundamental principles and key techniques of the signal analysis system based on Ethernet.In chapter three, the thesis specifies the system's hardware construction and realization, including the hardware whole framework, realization of the DSP-based module taking on data acquisition and signal processing, and realization of Ethernet controller. Several involved technique problem are also discussed.In chapter four, the thesis detailedly describes realization of an embedded system completing Ethernet communication, based MC68EN360 32-bit CPU and VRTX real time OS. A software application based Client/Server module is given to make sure feasibility of the system's Ethernet communication.In chapter five, summarization for this thesis is given, and research prospect in relative fields is also discussed.
