This thesis studies the law of affecting de - noise result and the selection of the threshold and the wavelet function, the combination of wavelet and fft in the fault diagnosis of turbine - generator sets : by the de - noise anslysis of blocks and sin signals, concludes : to blocks signals, usually adopts soft threshold ; the law of affecting de - noise result is when use wavelet auto - de - noise, with the increasing of decomposed level, the de - noise result becomes worse while the level blow the 3, when the level above 3 and when uses wavelet packet, it is the other way round ; the best de - noise methods of the signal is that uses " dbl " wavelet function, three level, soft and " rigrsure " threshold
本文研究了分解層數對消噪結果影響的規律和閾值、小波函數的選取，結合小波分析與fft分析診斷汽輪發電機組的故障。通過對brocks和sin兩信號的分析，得出：對blocks信號進行分析一般採用軟閾值；分解層數對消噪結果影響的規律為用小波自動降噪在分解層數小於3時，隨著分解層數的增加，消噪結果變好，反之，則變差，用小波包降噪時隨著分解層數的增加，消噪效果變好；適宜選用dbl小波軟rigrsure閾值自動消噪。This paper develops a whole - course alarm unit for pulsing vacuum high - pressure steam sterilization to monitor hydraulic pressure, vacuumizing ability, sterile time, sterile pressure and drying time. the unit alarms if any parameter mentioned above is out of order
現特設計一種滅菌全過程監測的報警裝置，可對水源壓力、高壓蒸汽滅菌器真空度、滅菌器夾層壓力、滅菌器內室壓力及計時進行實時監測，當任一程序在使用中出現異常時，報警裝置將發出準確部位的報警信號，提醒工作人員及時排除故障，保障滅菌效果。The main contents and the creationary outcomes of this paper are described as follows : ( 1 ) the limitation of the fuzzy general judge is found by analyzing its application in steam turbine generator - set ' s fault diagnosis and a multi - layer fuzzy diagnosis model which can overcome these limitations is put forward
