Study On The Application Of FPGA In The Instrument Of Hydrogenerator's Efficiency Measurement

Intelligent instrument is a measurement that has a microprocessor inner and behaves intelligently. Recently, owing to the development of microelectronic technology, microprocessor's power increases quickly. It has become current interest of measurement research to improve instrument's ability and precision by new devices.Attribute to the limitation of conventional current-meter measurement, we introduce FPGA technology in the design of hydrogenerator efficiency measurement. The application of FPGA chip makes it possible to improve system's precision and simples the circuit architecture. First contents about LONWORKS field-bus technology and methods of system design using FPGA chips are referred in the paper. On the base, the implementation of circuits in the FPGA chip is shown about efficiency measure of hydrogenerator. At the end, the result of measure tests the success of application.The paper is divided into six chapters. The forth three chapters are theoretical part including theory of hydrogenerator efficiency measurement, contents of LONWORKS field-bus , frame of the system and characteristic and developing procedure about selected FPGA chip. The fourth and the fifth chapters, mainly describe the hardware and software of hydrogenerator efficiency measurement, is the core of the paper. Some question worthy to pay attentin has been discussed deeply. In last chapter we draw conclusions for the system design and prospect next steps for the future.The paper maybe value to those who ready to use FPGA chips in their designs or be reference for development of neuron node based on LONWORKS field-bus technology.
