Abstract

The invention discloses a self-powered device and an ocean background acoustic field observation system. The self-powered device for the ocean background acoustic field observation system comprises apower supply monitoring circuit, multiple groups of lithium battery packs, a charging circuit and a self-powered power supply, wherein the power supply monitoring circuit is used for monitoring voltage of various lithium battery packs and sending out a charging instruction when the lithium battery pack of which the voltage is smaller than a preset voltage threshold exists; and the charging circuitcan switch a charging object of the self-powered power supply according to the charging instruction, so that the self-powered power supply charges the lithium battery pack of which the voltage is smaller than the preset voltage threshold, thereby carrying out sustained continuous power supply for an acoustic acquisition unit when the self-powered device is applied to the ocean background acousticfield observation system to achieve the long-lived continuous observation target of the ocean background acoustic field observation system. Researches on ocean background acoustic field characteristics and model can be better served by adopting long-lived continuous observation data collected by the ocean background acoustic field observation system.

Description

technical field [0001] The invention relates to the field of ocean observation, in particular to a self-powered device and an ocean background sound field observation system. Background technique [0002] With the development of ocean acoustics, the importance of observation and research of ocean acoustic field including background acoustic field becomes more and more prominent. At present, the working time of the existing ocean acoustic recording system is generally short, as short as a few days, as long as several months. Moreover, in order to reduce power consumption, the intermittent working mode is generally adopted, and most of the time is actually in a dormant state. According to the needs, the sound wave collection work is started according to the set time, and the dormant state is entered again after recording for a period of time. Because the recording is not continuous and uninterrupted, the recording cannot be collected during the dormant period, so the recorded...
