Cable type acoustic emission subsurface buoy capable of monitoring underwater equipment in real time and monitoring method of cable type acoustic emission subsurface buoy

Abstract

The invention relates to the field of marine acoustic instruments, in particular to a cable type acoustic emission subsurface buoy capable of monitoring underwater equipment in real time and a monitoring method thereof.The cable type acoustic emission subsurface buoy comprises ashore equipment, underwater equipment and a submarine cable used for connecting the ashore equipment and the underwater equipment, the ashore equipment comprises photoelectric signal conversion equipment, information source equipment, power amplification equipment, time service equipment, uninterruptible power supply equipment and state display and monitoring equipment; the underwater equipment comprises transducer equipment, a subsurface buoy supporting and protecting structure, a photoelectric separator, a photoelectric conversion module, a sealed cabin, a power conversion and main control module and a plurality of sensing equipment. The cable type underwater acoustic emission subsurface buoy has the basic functions of the cable type underwater acoustic emission subsurface buoy, real-time underwater equipment state monitoring and fault positioning can be achieved, maintenance and guarantee of testers are facilitated, long-time underwater normal operation of the subsurface buoy is guaranteed, and the maintenance and guarantee difficulty and cost of the subsurface buoy are greatly reduced.

Description

technical field [0001] The invention relates to the field of marine acoustic instruments, in particular to a cable-type acoustic launching submersible buoy capable of real-time monitoring of underwater equipment and a monitoring method thereof, which can be used for underwater acoustic physics research, marine survey, communication, navigation and positioning, and national marine security, etc. many research fields. Background technique [0002] Patent CN111010210B "A Cabled Underwater Acoustic Launching Submersible and Its Method" proposes a cabled underwater acoustic launching submersible based on a shore-based experimental station. , Working long hours, not limited by bad weather and energy supply. This acoustic launch submersible is composed of onshore signal source equipment, power amplification equipment, timing equipment and uninterruptible power supply equipment, through submarine cables laid on the seabed, and underwater single transducer equipment, submersible str...
