초록

일반적인 선박 내 통신은 재질의 특성상 기존 RF기반 무선통신 기술을 적용하는 데 제약이 따른다. 가시광통신 기술은 가시광을 통신수단으로 하기 때문에 전파제약이나 간섭 같은 기존 무선통신 기술의 문제점을 해결할 수 있으며, LED조명을 활용한 통신과의 융합으로 추가적인 설비 요구가 상대적으로 낮고, 가시광을 이용함에 따라 인체에도 무해하다는 장점이 있다. 본 논문에서는 256Kbps급, 5m 전송 거리 급의 가시광통신 기술을 선박 내 통신에 적용함으로써 일반적인 RF통신기기 적용이 어려운 여건에서의 응급호출 시스템 솔루션을 제안하고, 제안 시스템의 실제구현과 시험을 통하여 그 타당성을 검증한 결과를 제시하였다.

Due to metallicity of materials, a vessel has a limitation to adopt RF-based wireless communication technologies for the inner communication means. Visible Light Communication(VLC) can be a sound alternative to dissolve such a limitation. Using a visual light as a transmission medium, VLC is free from radio interferences and restriction of radio usages which are typically related to RF-based wireless communications. In addition, VLC can not only require the facility cost relatively low because of being possibly converged with existing LED illumination, but also be harmless to the human body. This paper proposes an indoor location-based emergency call service system solution for ships using the VLC technology that supports 256Kbps data rate and 5m transmission distance. This paper presents real implementation and testing results of the solution which verifies the propriety of the proposal.
