Abstract

본 발명은 퍼스널 컴퓨터를 이용하여 어군 탐지에 따른 정보를 용이하게 저장하고 이후에도 저장한 정보를 용이하게 재생할 수 있도록 하기에 적합한 어군 탐지기에 관한 것으로, 종래 기술에 따른 칼라 어군 탐지기는 그 이전의 기록식 어군 탐지기에 비하여 영상 판독력이 뛰어나지만 기록의 보존과 보존된 기록의 재생이 어려웠고 가격고 고가이기 때문에 비경제적 이었으나, 본 발명에서는 저가이면서 일반화된 퍼스널 컴퓨터를 이용하여 어군 탐지기를 실현함으로써 정보의 저장 및 재생이 용이 즉, 범용화되어 있는 퍼스널 컴퓨터를 이용하는 칼라 어군 탐지기이므로 일반적인 어선 어업의 어획 생산성을 높이는 데 이용할 수 있으며, 정보의 저장 및 재생이 용이함으로써 어체장 계산 및 분포, 자원량 변동 등의 연구에도 응용이 가능하므로 이와 같은 어군 탐지기를 좀 더 발전시키면 어자원 조사용 계량 어군 탐지기의 국산화에 기여할 수 있으며, 항해 혹은 입출항시나 협수로 통과시 음향 측심기로 이용할 수 있고 초음파 송수신부(4, 28)의 성능에 따라 해저 측량용 음향 측심기, 심해 측심기, 해저 지층 구조 조사용 등으로 활용이 기능하므로 상기 결점을 개선시킬 수 있는 것이다.The present invention relates to a fish finder suitable for easily storing information according to fish detection using a personal computer and easily reproducing the stored information thereafter. Although the image reading ability is superior to that of the fish locator, it is uneconomical because the record preservation and reproduction of the preserved record were difficult, and the price and cost are high. And because it is easy to reproduce, that is, a color fish group detector using a general-purpose personal computer, it can be used to increase the fishing productivity of general fishing vessels.In addition, it is easy to store and reproduce information. Application is possible Further development of the fish finder can contribute to the localization of the fish finder used for surveying fish resources, and can be used as an acoustic echo sounder when sailing, entering and leaving, or when passing through narrow channels. It is possible to improve the above-mentioned drawbacks because the function is used for the sounder, deep sea sounder, seabed structural investigation.
