Abstract

The invention discloses a real-time transmission multifunctional ocean bottom seismograph, which comprises an instrument cabin, an underwater acoustic modulator demodulator, an unhooking mechanism and a settlement coupling rack, wherein the instrument cabin comprises a glass instrument cabin and a plastic instrument cabin; the glass instrument cabin is fixedly arranged in the plastic instrument cabin; the unhooking mechanism is positioned on the top end of the plastic instrument cabin; the underwater modom of the underwater acoustic modulator demodulator is fixedly arranged on the side surface of the unhooking mechanism; the unhooking mechanism and the settlement coupling rack are fixedly connected by a tensioning steel wire; and the instrument cabin is fixed in the settlement coupling rack. Because the advanced underwater acoustic modulator demodulator and the advanced acoustic bandwidth frequency spread technology are adopted by the real-time transmission multifunctional ocean bottom seismograph disclosed by the invention, the underwater real-time communication function of the real-time transmission multifunctional ocean bottom seismograph is realized, the problems of low reliability, low data rate and high power consumption and the like of the traditional product in underwater communication are effectively overcome, and the real-time transmission multifunctional ocean bottom seismograph is suitable for the shallow sea marine geology observation.

Description

technical field [0001] The invention relates to the field of marine exploration, specifically to the technical field of marine seismic observation and underwater acoustic propagation technology, and in particular to a multifunctional seabed seismograph with real-time data transmission. Background technique [0002] The Institute of Geology and Geophysics of the Chinese Academy of Sciences is the main unit for the development of submarine seismometers in my country, and has undertaken most of the development tasks of submarine seismometers in China. During the Eleventh Five-Year Plan period, in the national major scientific research equipment development project supported by the Ministry of Finance, the seven-channel multi-functional broadband submarine seismograph independently developed by the Institute of Geology and Geophysics, Chinese Academy of Sciences broke the monopoly of foreign countries on my country's submarine broadband seismographs. It has been successfully appl...
