Development situation and prospects of seismometer

摘要

Seismometer is used to collect the seismic wave signals and accurately reflect the movement of the ground. Its performance will directly affect the analysis of the whole seismic wave. With the development of science and technology, especially when the introduction of electronic feedback technology and the development of digital seismic, the development direction of seismometer is high sensitivity, wide band, anti-interference and low power consumption. In this paper, the mechanical structure and energy transfer mode of several traditional seismometers are introduced. Looking forward to the new development direction of seismometer, the research development and application prospect of seismometer MEMS seismometer, fiber Bragg grating seismometer and electrochemical seismometer are also analyzed. The direction of the development of the Seismometer is intelligent, miniaturization and precision. It will get more and more attention from experts in related fields.
