低成本声音和振动数据记录软件简化了编程和信号采集 4月10日新闻――美国国家仪器有限公司今天宣布推出NI声音和振动测量组件5.0版,该新型交互式声音和振动分析软件包括NI声音和振动助手。该声音和振动测量组件5.0版是NI最全面的分析和信号处理工具,该工具用于噪音,振动和声振粗糙度测量,机械状况监测以及音频测量应用。 新型声音和振动助手是一个交互式的软件,用于快速采集,分析以及声音和振动测量。声音和振动助手具有基于配置,灵活测量库以及开放式分析功能,声音和振动助手设计通过一个独特的基于软件的测量方法快速采集数据,以生成客户定制的应用,通过拖放交互式分析、采集环境以及快速测量配置来简化采集和分析噪音和振动信号的过程。新型软件目前提供一种方式:即不间断地与变化地数据分析设置相结合,同时将数据存入硬盘以便以后更多分析。例如,工程师可以改变倍频程光谱称重和带宽,在记录整体振动数据的同时记录声音水平数据或者调整窗口以适合功率谱。声音和振动助手运用通用文件格式(UFF58)文件I/O支持扩展了分析功能和程序,工程师可以从NI仪器24位动态信号采集设备(DSA)中采集数据,包括低成本,四通道l NI USB-9233模块,然后在其他普通声音和振动分析应用中,包括模块分析软件,简单共享。 声音和振动测量组件5.0版还拓展了NI LabVIEW分析功能,具有LabVIEW分析可见光谱测量功能,用于声音测量,片段倍频程分析,频率分析和命令自动跟踪,用于军用/航空以及机械设计和建筑设计应用。通过时域分析和ANSI 和 IEC fractional-octave analysis目前可以适用于声音和振动水平趋势,同时频率响应,带内功率趋势和扭曲倾向可以通过频率域分析获得。工程师运用声音和振动测量组件5.0版的50多个直接执行功能可以更快速而有效的应用声音和振动软件,同时将该组件运用于硬件I/O,包括多种装置中信号生成和采集,以及引入信号过滤,开窗和取平均值。 声音和振动测量组件5.0版与LabVIEW和动态信号采集(DSA)产品运用集成采集和分析为测量试验共同提供先进的分析功能。 original text: [COLOR=#708090]NI Introduces Sound and Vibration Measurement Suite 5.0 for Interactive, Software-Based Measurement Programming and Signal Acquisition Simplified With Low-Cost Sound and Vibration Data Logger Software April 10, 2007 – National Instruments today announced the release of the NI Sound and Vibration Measurement Suite Version 5.0, the new interactive sound and vibration analysis software that includes the NI Sound and Vibration Assistant. The Sound and Vibration Measurement Suite 5.0 is the most comprehensive National Instruments collection of analysis and signal processing tools for noise, vibration, harshness (NVH); machine condition monitoring; and audio test applications. The new Sound and Vibration Assistant is interactive software for quickly acquiring, analyzing and logging acoustic and vibration measurements. With a configuration-based, flexible measurement library and open-analysis capability, the Sound and Vibration Assistant is designed for quick data capture through a unique software-based measurement approach to create customized applications. The Sound and Vibration Assistant is designed to simplify the process of acquiring and analyzing noise and vibration signals by offering a drag-and-drop, interactive analysis and acquisition environment and rapid measurement configuration. The new software now offers a way to continually interact with varying data analysis settings while logging data to disk for more analysis later. For example, engineers can vary the weighing and bandwidth of an octave spectrum while recording sound-level data or adjust the window applied to a power spectrum while recording overall vibration readings. The Sound and Vibration Assistant extends analysis functions and routines with Universal File Format (UFF58) file I/O support. Engineers can acquire data from National Instruments 24-bit dynamic signal acquisition (DSA) devices, including the low-cost, four-channel NI USB-9233 module, and then share it easily between other common sound and vibration analysis applications including modal analysis software. The Sound and Vibration Measurement Suite 5.0 also extends the analysis functionality of NI LabVIEW with LabVIEW analysis VIs for performing audio measurements, fractional-octave analysis, frequency analysis and order tracking for automotive, military/aerospace and mechanical and structural design applications. Sound- and vibration-level trending is now available through time-domain analysis and ANSI and IEC fractional-octave analysis, while frequency response, power-in-band and distortion trending are available through frequency-domain analysis. Engineers can more quickly and efficiently begin sound and vibration applications with more than 50 ready-to-run examples from Sound and Vibration Measurement Suite 5.0 while using the suite for hardware I/O, including the generation and acquisition of signals from a variety of devices as well as filtering, windowing and averaging incoming signals. The Sound and Vibration Measurement Suite 5.0 works with LabVIEW and Dynamic Signal Acquisition (DSA) products and provides advanced analysis capabilities for measurement tests using integrated acquisition and analysis.[/COLOR]
