摘要

基于虚拟仪器技术，在HLD-RLC-III型号的RLC综合实验仪基础上，利用数据采集卡将实验仪输出的模拟信号转换为计算机能够处理的数字信号，配合LabView编制的虚拟仪器程序，实现测量RLC串联谐振电路特性的实验系统的设计与搭建。与传统的实验方案相比，其数据采集、信号处理、数据显示等功能都是虚拟仪器程序实现的，这些功能可根据实验内容重新设计，因此该系统在实验内容方面具有灵活的拓展性，利用该系统不仅能够完成测量RLC串联电路基本特性的基础实验教学，同时还能够对学生开展设计性实验训练，以此调动学生的积极性和创造性，提高学生的实践动手能力。

Abstract:

Based on the virtual instrument technology, based on the HLC-RLC-III model RLC comprehensive experimental instrument, the data acquisition card is used to convert the analog signal output by the experiment instrument into a digital signal that can be processed by the computer, and the virtual instrument program compiled by LabView is used to realize the measurement. Design and construction of an experimental system for the characteristics of RLC series resonant circuits. Compared with the traditional experimental scheme, the functions of data acquisition, signal processing and data display are realized by virtual instrument programs. These functions can be redesigned according to the experimental content. Therefore, the system has flexible expansion in experimental content. The system can not only complete the basic experimental teaching of measuring the basic characteristics of the RLC series circuit, but also carry out design experimental training for students, thereby mobilizing the enthusiasm and creativity of students and improving students' practical ability.

Key words: RLC series resonant circuit resonance curve data acquisition card RLC comprehensive experiment instrument
