摘要
本题目属于应用设计类,设计内容包括:相位差检测的方法(相关分析法、频谱分析法、过零检测法等)研究;多种方法在虚拟仪器设计平台上的仿真实现;采用各种方法的虚拟相位差测量仪的分析比较。
论文采用三种方法中的前两种,比较两种方法设计成的仿真仪在测量波形相位差的精度和程序上的不同,通过相关资料了解它们在实际运用中各自的适用场所及其优缺点。充分了解虚拟仪器特别是LABVIEW的功能强大性。
论文的第一部分是对虚拟仪器,主要是虚拟仪器的大体介绍和相位差测量仪的在工业上的应用;第二部分主要是对LABVIEW的简介和其运行的环境的概述;第三部分主要讲述本次课程设计中要用到LABVIEW中的功能函数以及相关法、频谱分析法等相位差测量方法原理;第四部分则列出本次课程设计要用到的LABVIEW的内容及各种方法在LABVIEW平台下的实现。最后是对本次设计的总结。
关键词:相关法、频谱分析法、过零检测法、相位计
Abstract
The topic is application design category, design elements include: phase difference detection method (correlation analysis, spectrum analysis, zero-crossing detection, etc.); various methods in the design of virtual instrument platform Simulation; using various methods of virtual phase meter analyzed.
Papers using three methods of the former two. Comparing the two methods designed instrument in the simulation waveform measurement accuracy and the phase difference of the different procedures, through the relevant information on the practical application of their respective places of application and their advantages and disadvantages. Fully aware of virtual instruments, especially LABVIEW powerful nature.
Among the first part of the virtual instrument, is the main design of this phase difference measuring instrument of industrial applications; The second part was to brief the Labview and its operating environment overview; The third part mainly on the current curriculum design, the use of related laws, such as spectrum analysis phase difference measurement principle; Part IV sets out the course of the design LABVIEW use of the content and methods in LABVIEW Platform achieved.
Keywords: correlation, spectrum analysis, zero-crossing detection, phasemeter
