Description

Microseismic sensor balance system

The present invention relates to a miniature seismic sensor balancing system, and more particularly to a miniature seismic sensor balancing system capable of accurately measuring seismic waves in various terrains.

In general, when an earthquake occurs, two kinds of seismic waves, P wave (primary wave) and S wave (secondary wave), are generated. The true destructive property is S wave, and the P wave is transmitted faster than S wave. By obtaining the P-wave measurement information before the S wave reaches the surface of the formation, an alarm can be issued first to reduce the severity of the disaster.
When we want to measure the P wave of the seabed stratum, it is usually placed in the sea and placed on the seabed by a submarine seismograph. The submarine seismograph defines an X-axis direction, a Y-axis direction and a Z-axis direction.

However, the submarine seismograph does not have an axial adjustment mechanism. When the submarine seismograph is placed on an uneven seabed, the sensors cannot be reset to the X-axis direction defined by the submarine seismograph. The Y-axis direction and the Z-axis direction, so the sensors of the submarine seismograph will not be able to effectively obtain the measurement information of the P wave when the earthquake occurs, so the terrain that can be placed will be greatly limited.
