All sea depth profile stereo buoy observation system based on photoelectric composite cable

The invention discloses an all sea depth profile stereo buoy observation system based on a photoelectric composite cable. The observation system comprises a sea surface buoy platform, a buoy anchor system and a sea bottom observation system which are successively connected; the sea surface buoy platform is provided with a data acquisition system and a power supply system; the buoy anchor system comprises a photoelectric composite cable, and a plurality of branches are separated on the photoelectric composite cable through a plurality of separation boxes and carried out photoelectric separation, and each branch is used for hanging and mounting observation sensors; and a data acquisition unit collects data of the observation sensors on the photoelectric composite cable and in the sea bottomobservation system to realize observation of a profile and a sea bottom. The observation system adopts the separation boxes on the photoelectric composite cable for photoelectric separation, continuous power supply of the sen
