Abstract

본 발명은 해저의 음향신호를 포착하여 음향패턴을 분석하는 장치인 음향감시 시스템에 있어서, 수중청음기(1)와 증폭기(2)에서 발생하는 소자 장음과 전자파 장해에 의해 출력단에서 신호대 잡음비(SNR)가 저하되는 것의 방지와 또한 상기 소자의 진동에 의한 음전달의 손실을 방지하기 위한 장치에 관한 것으로, 수중청음기(1)에서 발생하는 소자자체의 잡음성분과 또한 수중청음기(1)와 커플링에 의한 전자파 장해 문제 제거와 신호감도의 개선을 과제를 해결하기 위한 장치를 제공하기 위한 것이다.The present invention relates to an acoustic monitoring system, which is a device for capturing an acoustic signal from a seabed and analyzing acoustic patterns, wherein a signal-to-noise ratio (SNR) is output at an output stage by element long sound and electromagnetic interference generated from the hydrophone 1 and the amplifier 2. The present invention relates to a device for preventing the degradation of the device and for preventing the loss of sound transmission due to vibration of the device, and the noise component of the device itself generated in the hydrophone 1 and also the coupling with the hydrophone 1 The present invention provides an apparatus for solving the problem of eliminating electromagnetic interference problems and improving signal sensitivity.

이를 위해 본 고안에서는 수중청음기(1)에서 방사하는 전자기파를 쉴드하고 음전달 손실을 최소로 하기 위하여 쉴드메쉬 고정링(51)이 사용되었으며, 쉴드메쉬 고정링(51)과 증폭기 커버(59)간의 그라운드 루우프 발생을 억제하기 위하여 증폭기 커버(59)의 한쪽만 접지시키는 방법을 선택하였다.To this end, in the present invention, a shield mesh fixing ring 51 is used to shield electromagnetic waves radiated from the hydrophone 1 and minimize sound transmission loss, and between the shield mesh fixing ring 51 and the amplifier cover 59. In order to suppress the occurrence of ground loops, a method of grounding only one side of the amplifier cover 59 was selected.

상기의 작용과 병행하여 패키지(11)에서 발생하는 진동을 억제하고 완화시키기 위하여 이로브(52)(53)(54)를 사용하였으며 수중청음기(1)와 증폭기(2)도 일체형으로 제작하였다.In parallel with the above operation, the robes 52, 53, and 54 were used to suppress and mitigate vibrations generated in the package 11, and the hydrophone 1 and the amplifier 2 were also integrally manufactured.

상기와 같은 방법으로 음향감시 시스템의 수중청음기(1)와 증폭기(2) 조립체에서 발생하는 접음성분 효과적으로 제거하여 해저 정보의 정확한 판독이 가능토록 하여 음향패턴 분석의 정밀도 향상에 크게 기여할 수가 있다.In this way, by effectively removing the fold components generated in the hydrophone 1 and amplifier 2 assembly of the acoustic monitoring system, it is possible to accurately read the seabed information, which can greatly contribute to improving the accuracy of the acoustic pattern analysis.
