Power supply unit provided in the acoustic sensor of the passive towed line array sound detector

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply unit installed in an acoustic sensor unit of a towed array sonar system that detects the exact position of a sound source (type of sound source, speed of movement of a sound source) with underwater sound. The power supply control terminal for controlling the applied power is provided in the manual tow-type sound detector, and the sub-power control stages are respectively provided in the vibration isolation module, the signal transmission module, and the sound module constituting the sound detector. Control the voltage of 40 ~ 60V at the power control terminal first and adjust it to the stable voltage of 38V, and then apply the stable 38V voltage to the sub power control terminal provided in each module. Each module can operate normally by applying the set voltage which is regulated by the voltage (eg ± 15V or + 5V).
