摘    要:本文对传送涡轮钻转速信号的泥浆信道的干扰与噪声特性作了分析,从理论上阐述了从强的周期性干扰与噪声中实时检测出转速信号频率的谱分析法。提出了干扰带的概念,并详细分析了不同窗函数在已定干扰带的条件下所需的数据时宽。根据噪声强度推导了用平均法降低噪声功率谱方差所需的分段数以及总的数据时宽。

关 键 词:涡轮钻具  转速  泥浆  信道  谱分析  频率

Abstract:The characteristics of the interference and noise of thehydraulic channel for the transmission of turbodrill rotating speed signal are analyzed and spectrum analysis method for real time measuring the frequency of this signal among strong periodic interference and noise is explained thep-retically.A concept of "interference band" is introduced. The time of data width needed for several window functions under certain interfence band is analyzed in detail. The number of segments needed for lowering the variance of the power spectrum of the noise with average method and the total time of data width are also developed.
Keywords:Turbodrills  Speed  Mud  Channels  Spectral analysis  Frequency
