The invention provides a deep-sea seismic
data acquisition towing cable based on a deep-sea
robot and an acquisition method. The deep-sea
robot is used for
towing the array type marine seismic
data acquisition towing cable in the
deep sea, and single-component or multi-component marine seismic data can be directly acquired in the
deep sea. The pull-type or bottom-sinking array type marine seismic
data acquisition cable is composed of three-component wave detectors or sensors, piezoelectric crystals or
optical fiber sound pressure hydrophones and electronic or
optical fiber three-component attitude sensors, wherein the three-component wave detectors or sensors, the piezoelectric crystals or the
optical fiber sound pressure hydrophones and the electronic or optical
fiber three-component attitude sensors are evenly distributed in the cable. The head end and the
tail end of each seismic data acquisition towing cable are respectively towed by a deep-sea
robot; the cable is connected with a seismic data acquisition and storage instrument or a modulation and
demodulation instrument on the deep-sea robot; and a high-precision
chip-level
atomic clock in the seismic data acquisition and storage instrument or the modulation and
demodulation instrument is used for timing the acquired marine seismic data and carrying out
time synchronization and
data processing on excitation signals of an
underwater controllable air gun seismic source in the later period.
