摘要： PROBLEM TO BE SOLVED: To surely determine the generation of abnormal sounds, using a comparatively simple signal processing.
SOLUTION: A separation part 122 separates a sound collection signal, collected by a sound collection sensor 11, into a plurality of frequency bands. A channel determination part 123 measures the signal for each frequency band for a prescribed period, calculates the reference value for each frequency band, determines a permissible range for each frequency band on the basis of the reference value for each frequency band, compares the signal for each frequency band separated by the separation means with the corresponding permissible range, and determines the generation of abnormal sound, when at least the signal of at least one of the frequency bands exceeds the permissible range. Because the processing is performed not by frequency analysis or waveform analysis, but by only signal level determination of the plurality of frequency bands, the signal processing is comparatively simple and a low-cost signal processing chip may be utilized. Furthermore, because the reference value is calculated for each frequency band at each installation location, the permissible range matching with the surrounding environment is determined.

摘要翻译：要解决的问题：使用比较简单的信号处理来确定异常声音的产生。解决方案：分离部分122将由声音收集传感器11收集的声音收集信号分离成多个频带。频道确定部分123测量每个频带的规定时段的信号，计算每个频带的参考值，根据每个频带的参考值确定每个频带的容许范围，将每个频带由分离装置分离具有相应的允许范围，并且当至少一个频带的信号至少超过允许范围时，确定异常声音的产生。由于处理不是通过频率分析或波形分析进行的，而是仅通过多个频带的信号电平确定，信号处理相对简单，并且可以利用低成本的信号处理芯片。此外，由于为每个安装位置处的每个频带计算参考值，因此确定与周围环境匹配的容许范围。版权所有（C）2008，JPO＆INPIT

摘要：複数のピアノ線などの振動子を剛体に固定し、様々な周波数を含む音や振動を即座に共鳴分離させ目に見えるようにする音・振動の共鳴分離装置である。表現を変えればフーリエ変換を瞬時に実行する聴覚のモデルとなる装置でもある。第2図において1から20までは様々な固有振動を持った振動子である。第4図において音を電気信号に変換するマイクから装置本体に入力すると、電子回路28によって増幅・制御され振動変換装置であるスピーカー24に出力され、音は増幅された縦振動となり、剛体21を縦の方向に振動させる。その振動は剛体に固定された固有振動を持つ振動子1〜20に伝わり、その振動の周波数に応じた振動子だけが振動する。ボリュームつまみ25は振動の大きさを調節するためにある。周波数制御つまみはsine波の発信周波数をコントロールする。

摘要： PROBLEM TO BE SOLVED: To enhance the accuracy of anomaly detection on a movable body by removing noise from data obtained through measurement on the movable body.
SOLUTION: Measurement data (including the velocity of the movable body) on the movable body are inputted and stored in a measurement data storage medium 103. The measurement data are decomposed every hour into frequency components by a frequency analysis means 104 to select frequency components having values equal to or larger than a threshold as analyzing object frequencies, and the selected frequency components are further decomposed every hour into frequency components. Occurrence periods of signals of the object frequencies are calculated every hour from a result obtained by the second frequency decomposition. A correlation calculation means 105 calculates a correlation between the occurrence periods of signals and the velocity to extract data highly correlated to the velocity as effective data in analyzing anomaly on the movable body.

摘要： PROBLEM TO BE SOLVED: To provide a vibration predicting system for an object, capable of high-precisely predicting the waveform of the vibration of the object and the maximum amplitude thereof, even if the fluctuation of fluid is unsteady.
SOLUTION: Firstly, by providing time-history data on the flow velocity of the fluid, this fluctuation in the flow velocity is decomposed by discrete wavelet transformation (S102). The time-history data is stored, for example, on a disk as sampled digital data. Secondly, individual decomposed fluctuations of the flow velocity are converted into fluid forces. Here, the determined fluid forces are represented as functions of the frequency (S104). By multiplying the fluid forces expressed as functions of the frequency, by the dynamic admittance expressed as a transfer function of a subject object (S106), the vibration of the object in a decompressed state can be expressed as the function of frequency. Finally, by composing the vibrations of individual objects which are determined as the functions of the frequency, by discrete wavelet inverse transformation, the overall vibration waveform of a time function can be obtained (S108).

摘要翻译：要解决的问题：即使流体的波动不稳定，也可以提供能够高精度地预测物体的振动波形及其最大振幅的物体的振动预测系统。解决方案：首先，通过提供流体流速的时间历程数据，通过离散小波变换对流速的波动进行分解（S102）。时间历史数据例如作为采样的数字数据存储在盘上。其次，个体分解的流速波动被转换为流体力。这里，所确定的流体力被表示为频率的函数（S104）。通过将表示为频率的函数的流体力乘以表示为被摄体的传递函数的动态导纳（S106），可以将处于解压缩状态的物体的振动表示为频率的函数。最后，通过组合作为频率函数确定的各个物体的振动，通过离散小波逆变换，可以获得时间函数的整体振动波形（S108）。版权所有（C）2005，JPO＆NCIPI
