By utilizing the positioning and communicating device, the problems of navigational positioning and remote communication of an oceanic earthquake sensing detector are solved, and the real-time detection of the oceanic earthquakes is realized; by utilizing the energy supply device, power is generated by virtue of solar energy and wave energy, and the energy is supplied for the oceanic earthquake sensing detector for a long time, so that the long-term detection of the oceanic earthquakes is realized; the sensing detection and signal processing device adopts an optical fiber laser hydrophone array, and noise reduction is respectively carried out on hardware and software, so that the sensitivity of the oceanic earthquake sensing detector is improved, and the accurate detection of low-earthquake-magnitude long-distance earthquake waves is realized. The movable long-term real-time detector has the advantages that the technical requirements on distribution and recycling are low, the cost is low, the real-time data transmission is realized, and the like.

Description

technical field [0001] The invention relates to the technical field of marine seismic detection, in particular to a mobile long-term real-time marine seismic detector. Background technique [0002] With the development of marine science and technology, people pay more and more attention to the physical properties of the earth's interior and earthquake disasters. Marine seismology has gradually emerged and has become a hot spot and frontier of earth science research. Because oceans cover most of the plate boundaries and most earthquakes occur on the ocean floor, models of the Earth's interior structure obtained from continental seismic observations are insufficient to represent the deeper structure of the ocean. Modern digital broadband seismic stations provide the possibility for us to study finer and deeper earth structures. However, most of the seismic stations are mainly distributed on land. In the ocean, which accounts for two-thirds of the earth's surface, especially i...

Problems solved by technology

The shell is made of sound-transmitting material. This kind of marine geophone can overcome the problem that the geophone used in the existing ocean survey has poor reception performance and poor reception effect in low-frequency band signals.

[0006] None of the above existing technologies can fill the gap in low-cost long-term real-time marine seismic observation in my country, and the development of marine seismic science and earth science in China still needs to be further promoted
