Abstract

Marine accidents are mostly caused by medium and small ships, and are continuously increasing. In this paper, we propose an architecture of the speech synthesis based automatic safety navigation support service providing system for small ships that equiped onboard systems compared with vessels. The main purpose of the system is to prevent marine accidents by providing synthesized voice safety messages to nearby ships. The safety navigation support service is operated by connecting GPS and AIS to synthesize voice safety messages, automatically broadcast through VHF. Therefore, we developed a data processing module, a staged risk analysis module, a voice synthesis safety message generation module, and a VHF broadcasting equipment control module, which are components of the system. In addition, we conducted laboratory-level and sea-trial demonstration tests using the developed the system, which verified usefulness of the proposed service.

우리나라의 경우, 중소형선박에 의한 해양사고의 발생 비중이 상대적으로 매우 높으며, 통계에 따르면 각종 안전지원 장비의 탑재 의무화에도 불구하고 크게 감소되지 않고 있는 실정이다. 본 논문에서는 대형선박에 비해 상대적으로 탑재 장비가 적은 중소형 선박을 위한 음성합성 기반 자동 안전항해 지원 서비스 제공 시스템의 아키텍처를 제안한다. 시스템의 주목적은 주변 선박들에게 VHF 무전기를 통해 합성된 음성 안전 메시지를 자동으로 제공하여 해양사고를 예방하는 것이다. 안전항해 지원 서비스는 GPS 및 AIS를 연계하여 음성 안전 지원 메시지를 합성하고, VHF를 통하여 자동으로 방송해주는 형태로 동작된다. 따라서 시스템을 구성하는 데이터 처리 모듈, 단계별 위험도 분석 모듈, 음성합성 안전 메시지 생성 모듈, VHF 방송장비 제어 모듈 등을 개발하였다. 또한, 개발한 시스템을 활용하여 실험실 수준의 테스트와 해상 실증 시험을 진행하였으며, 이를 통해 서비스 유용성을 검증하였다.
