Abstract

In this study, an ICT-based underwater communication monitoring device for underwater structures is implemented based on lifting fixture that transport human bodies found on the seabed to sea level. The lifting fixture is packaged with a retback, sideback, and cartridge that injects air. Monitoring systems are developed in a mobile manner in a portable structure. The underwater ultrasonic sensor signal is supplied using a USB port, and the O/S consists of Linux. For the underwater communication dong test, a measurement test was conducted in real time from 6m to 40m in depth on the east coast. The ultrasonic sound sensor is converted to 2,400 bps to verify the transmission error according to the duality. The communication speed of sensor to monitoring is 115,200 bps, and the speed of communication from controller to receiver is 2,400 bps. In the commercialization stage of the lifting device, it is easy to develop a low-end type and the compatibility is wide.

본 연구에서는 해저에서 발견한 인체를 해수면까지 운반하는 인양백을 기반으로 수중구조를 위한 ICT 기반 수중통신 모니터링 장치를 구현한다. 인양백은 에어를 주입하는 리프트백, 사이드백, CO2 카트리지 등으로 패키지화 되어 있다. 모니터링 시스템은 휴대하기 용이한 구조로 모바일 방식으로 개발한다. 수중 초음파 센서 신호는 USB 포트를 사용하여 공급되며, O/S는 리눅스로 구성한다. 수중통신동시험은 동해안에서 수심 6m~40m까지 실시간으로 측정 시험을 진행한다. 초음파 음향센서는 2,400bps로 변환되어 2원화에 따라 전송오차를 검증한다. 센서에서 모니터링까지 통신속도는 115,200bps, 제어기에서 수신부까지 통신속도는 2,400bps를 사용한다. 리프팅 장치의 상용화 단계에서 로우엔드 타입 개발이 용이하고 호환성이 넓도록 한다.
