Abstract

The Mu-communication board supported by hybrid communication is designed with Cortex M3, which is a low power energy consumption 32-bit microcontroller. The Cortex M3 microcontroller has UART(Universal asynchronous receiver/transmitter) ports which can set appropriately using the command line interpreter (CLI) program with each port. URAT ports are used for hybrid communication modems, GPS modules, etc. When the socket type was compared with the short message service type, the socket type was proven to be better. By improving the receiving performance in the control and management system of the AtoN, data loss was minimized. During the testing of the socket and SMS, data was collected from each buoy for 12 hours every 1 minute and the receiving rate of the data was found to be more than 98.58 % and 99.42 % respectively.

하이브리드 통신을 지원하는 하이브리드 통신 신호처리 제어보드는 저전력의 32-bit 마이크로콘트 롤러인 Cortex M3로 설계하였다. 마이크로콘트롤러는 하이브리드 통신을 위한 모뎀과 GPS 모듈 등을 직렬 인터페이스하기 위한 UART 포트가 갖추어져 있으며, CLI(Command Line Interpreter) 프로그램은 각 포트의 인터페이스를 사용자 환경에 맞게 설정할 수 있다. 항로표지 원격관리 시스템에 사용되는 하이브리드 통신 신호처리 제어보드의 전송방식을 단문메시지 방식과 소켓 방식을 비교한 결과 소켓 방식의 우수함을 입증하였으며, 수신 성능의 개선을 통해 항로표지 원격관리 시스템의 데이터 손실을 최소화될 수 있도록 하였다. 실험은 12시간 동안 각 부표에서 매 1분마다 데이터를 취득하였으며, 데이터 수신율은 각각 98.58 %와 99.42 % 이상을 보였다.
