초록

본 연구에서는 기존의 우선 부표가 지니고 있는 문제점들을 해결할 수 있는 원근해 어로용 고성능 무선 부표 시스템을 개발하였다. 2진 FSK 변조방식과 우선부표용 송수신 프로토콜을 도입하여 사용시간을 대폭 개선하였으며, GPS 위치정보와 여러 계측정보를 수집한 후 모선의 탐지기 호출이 있을 경우 전송함으로써 쉽게 탐색이 이루어질 수 있도록 하였다. 개발된 우선부표는 평균 73일의 동작시간과 120km 이상의 동작시간과 120km 이상의 동작범위를 갖으며, 분실과 도난을 방지할 수 있다.

In this paper, high performance radio buoy system for inshore and deep sea fishery is proposed and implemented. Binary FSK modulation technique is used for real-time communication & control between buoys and buoy finder, and optimum access protocol is adopted for minimizing the power consumption of radio buoy system. Using the GPS and sensor techniques, location and environments of radio buoy can be accurately monitored and traced by the mother ship. Developed buoy system with 10 W transmitting power can cover over 120km coastal range and operate more than 73 days of battery life. Proposed digital coding methods can also assure high security from burglary and loss.
