FPGA在精密儀器研制中的應(yīng)用

摘要：精密儀器是儀器儀表學(xué)科中重要的組成部分，它主要是研究長度、熱工、電磁、光學(xué)、無線電、時間頻率等物理量所用的儀器儀表，它的研制中重要的技術(shù)指標就是精度，而FPGA技術(shù)作為現(xiàn)代數(shù)字電路設(shè)計中一種重要的廣泛應(yīng)用的手段，將其應(yīng)用于精密儀器的設(shè)計研制中的硬件實現(xiàn)部分，對提高精密儀器的精度具有重要的實際意義，使精密儀器研制上升到新的高技術(shù)平臺。將FPGA技術(shù)應(yīng)用于精密儀器的研制是當代信息社會發(fā)展研究的主流。
本文的主要目的是研究FPGA在精密儀器研制中的應(yīng)用。從論文題目進行剖析，主要分三個章節(jié)來進行介紹，首先，介紹FPGA的基本結(jié)構(gòu)、基本特點、設(shè)計流程、應(yīng)用范圍及它的發(fā)展趨勢，使大家對FPGA有個初步的認識。其次，介紹了精密儀器的有關(guān)知識，包括精密儀器的概念、精密儀器的發(fā)展史，重點闡述了精密儀器的設(shè)計研制過程。最后，通過FPGA在高分辨率感應(yīng)測井儀上應(yīng)用和FPGA在智能儀表中應(yīng)用的兩個實例，深入解析了FPGA在精密儀器研制中的應(yīng)用過程。

FPGA in the development of precision instruments

Abstract: Precision is the instrumentation disciplines important part of it is to study the length, thermal, electromagnetic, optical, radio, time and frequency of physical quantities used in instruments and meters, and its development in the important technical indicator that is accurate, and FPGA technology modern digital circuit design as a important means of widely used, its design and development of precision instruments used in the hardware part, to improve the accuracy of precision instrument has important practical significance, so that precision instrument development to a new high-tech platform. FPGA technology in the development of precision instruments of the modern information society the mainstream of development.
     The main purpose of this paper is to study the FPGA in the development of precision instruments. From the subject for parsing, this article mainly divided into three sections. First, to introduce the basic structure FPGA and basic characteristics and the design process, the scope of application and its development trend and set everyone to have a preliminary understanding of FPGA. Secondly, high precision instruments of knowledge, including the concept of precision instruments, precision instruments of development, the emphasis on instruments of the design of the development process. Finally, through FPGA on the high resolution induction logging instrument the application and FPGA in the intelligent measuring appliance the application two examples, has analyzed FPGA thoroughly in the precision instrument development application process.
