The invention discloses a small-size intelligent oceanic earthquake and electromagnetic
data acquisition system. The small-size intelligent oceanic earthquake and electromagnetic
data acquisition system comprises an intelligent acquisition
station arranged
underwater and two pairs of
electric field detection devices installed at the exterior of the intelligent acquisition
station; an ultra-short baseline
transponder, a
computer control system, a four-component earthquake data sensor unit, a
magnetic field sensor and a three-component attitude sensor are arranged in the intelligent acquisition
station; the output end of the four-component earthquake data sensor unit is connected with the four-component earthquake
data acquisition unit; the output end of the
magnetic field sensor is connected with a
magnetic field data acquisition unit; and an
electric field data acquisition device, the magnetic
field data acquisition unit, the three-component attitude sensor, the ultra-short baseline
transponder and the four-component earthquake
data acquisition unit are all connected with the
computer control system. With the small-size intelligent oceanic earthquake electromagnetic data acquisition system of the invention adopted, oceanic earthquake data, oceanic magnetotelluric data and oceanic controllable source electromagnetic data can be acquired simultaneously, and the data acquisition quantity of one-time construction can be improved manyfold, and target detection accuracy can be improved effectively.
