[0002] With the further development of seismology and earthquake prediction research and rapid response after major earthquakes, higher and higher requirements are put forward for earthquake detection work. However, the current earthquake detection equipment is not only complex in structure, but also has a single detection method and poor accuracy. , it is impossible to timely and accurately detect the occurrence of earthquakes. For example, Chinese patent document CN201110390546 discloses an earthquake detection method and system. The earthquake detection method and system can only perform earthquake detection from two aspects of tensor measurement and strain measurement. Very complex physical and chemical processes. During the earthquake process, the tensor and strain are very small, so the requirements for measurement accuracy are high, which makes the earthquake detection system unable to meet the existing needs in terms of accuracy.
