摘要
采用PC机与NI数据采集卡USB4431为硬件平台,LabVIEW为软件开发环境,设计了多通道声音信号采集分析系统。系统可以实现信号的同步实时采集、实时调理、存储及分析,提供多种数据处理算法模块。该系统已应用在工程噪音分析中,显示了其方便、实用等优势。
A multi-channel acquisition and analysis system for soud signal is designed by using PC and N1 USB4431 as hardware platform and LabVIEW as software development environment. The system realizes real- time signal acquisition, conditioning, storage and analysis, and provides several data processing algorithm mod- ules. The successful application in practical analysis of machine noise shows the effectiveness and convenience of the designed system.
