高可靠深井地震计输出符合性检验

深井井下地震综合观测对仪器的可靠性要求很高,为满足高可靠性的要求,我们提出了基于6个斜轴悬挂平动分量传感器的高可靠深井地震计解决方案.使用该方案的高可靠深井地震计的可靠性是普通三分量地震计的20倍,为了最大限度发挥高可靠深井地震计方案的优势,需要掌握各分量的工作状态.本文研究了所有6个分量传感器输出波形的特征,提出垂直...

Examination of Coherence for High Reliable Deep Borehole Seismometer

To meet the the high requirement on reliability of instruments for deep borehole seismic observation. a high reliable seismometer architecture with 6 same tilt suspension transducers is proposed. The reliability of this kind of seismometer is 20 times of a normal one. To take advantage of the 6 component architecture, the state of all the components should be known clearly. A set of methods for examination of consistency of a high reliable 6 component seismometer, includes examination of consistency of up-down waveform, examination of consistency of horizontal waveform, examination of consistency of XYZ output waveform, is given in this paper. The methods are helpful for determination of the state of 6 components, then help to decide which 3 components will be selected to get the best XYZ output waveform, then get the best specification of the high reliable 6 component seismometer.
