文章叙述了钠沸腾噪声探测研究进展,建立了离线和在线均可进行的高频和低频信号采集和处理系统,引进、开展、改进和编制了信号处理、故障诊断、事故报警和自回归模型分析等软件包。应用这些硬软件对水和钠沸腾噪声进行了探测和分析。结果表明,沸腾噪声信号的自功率谱密度(APSD)的幅值明显大于沸腾时的值,用自回归模型判别因子分析,可实现钠沸腾在线实时诊断和监护。
The article describes the research progress of sodium boiling noise detection, and establishes both high frequency and low frequency signal acquisition and processing system both offline and online, and introduces, develops, improves and compiles the signal processing, fault diagnosis, accident alarm and autoregressive model analysis Other packages. Use these hardware and software to detect and analyze water and sodium boiling noise. The results show that the amplitude of self - power spectral density (APSD) of boiling noise signal is obviously larger than that of boiling point. By using autoregressive model discriminant factor analysis, it is possible to realize on - line sodium boiling online diagnosis and monitoring.
