摘要
介绍了一种液压泵站噪声采集和分析系统的软硬件设计。该系统利用PC和工控机的声卡作为数据采集卡,辅以相应的分析软件,具有较高采样精度和中等采样频率,可实现液压泵站实验室或工业现场的实时噪声数据采集和分析。软件设计上,在MATLAB环境中通过在图形窗口中加入菜单及控制,实现了直接对窗口对象的操作,建立了一个适合用户需要的噪声数据实时分析处理平台。该系统具有实现简单、性价比和灵活度比较高的优点。
A sound acquisition and analysis system for hydraulic pump station was designed, which is based on computer sound card and the analysis software, can finish the real time sound data acquisition and analysis with higher accuracy and middling acquisition frequency in hydraulic pump station lab or the industry environments. The software can manage the objects by adding menus and controls to MATLAB figure windows. A platform was built for real time sound analysis in MATLAB environment. The system is convenient for realization, high cost-performance and high flexibleness.
