항로표지 원격관리시스템은 다양한 유무선 통신방식 즉, AIS, TRS, CDMA 등의 통신망으로 운영하고 있다. 이는 항로표지 시설이 육상과 달리 해상에 설치됨으로써 기후변화 및 도서지역 특성상 통신장애 발생이 잦으며, 안정적인 전원 공급이 요구되기 때문이다. 본 연구에서는 최근 통신기술인 사물지능통신(M2M) 게이트웨이 지그비 시스템과 CDMA망을 활용하여 안정적이고 저전력의 항로표지 원격관리시스템을 구성하여 활용하고자 한다.

Maritime traffic assessment is important to understand the characteristics of maritime traffic and to prevent maritime accidents. The maritime traffic assessment can be calculated from the ship trajectory data observed by using AIS(Automatic Identification System). This paper developes a maritime traffic assessment tool using ship's position and speed, course, time data from ships navigating waterways. The results are represented in terms of the number of traffic quantity and traffic distribution, speed distribution, geometric collision candidates. The developed tool will contributes to advance maritime traffic safety by VTS(Vessel Traffic Services).

Vessel traffic service(VTS) centers are equipped with RADAR, AIS(Automatic Identification System), weather sensors, and VHF(Very High Frequency). VTS operators use this equipment to observe the movement of ships operating in the VTS area and provide information. The VTS data generated by these various devices is highly valuable for analyzing maritime traffic situation. However, owing to a lack of compatibility between system manufacturers or policy issues, they are often not systematically managed. Therefore, we developed the VTS Bigdata Platform that could efficiently collect, store, and manage control data collected by the VTS, and this paper describes its design and implementation. A microservice architecture was applied to secure operational stability that was one of the important issues in the development of the platform. In addition, the performance of the platform could be improved by dualizing the storage for real-time navigation information. The implemented system was tested using real maritime data to check its performance, identify additional improvements, and consider its feasibility in a real VTS environment.

The high tech marine transportation infrastructure is an innovative transportation infrastructure that may be able to secure a safe transportation environment as well as efficient operation by connecting up-to-date skills including a broad range of wire and wireless communication-based information, control and electronics technologies. When integrated into the marine transportation infrastructure by the standard requirements, these standard technologies help monitor and manage navigational aids. After investigated on current status of marine transportation system, verified on integrating marine transportation systems, the standard requirements have to suggest a appropriate way of integrating marine traffic systems and proper way of using old marine traffic infrastructure.

The Wireless-LAN was developed and Wired-LAN substitution from the field which the space where it is restricted is special it used. But, from the field which is various the use is attempted to listen to recently. The shedding of blood which the oceanic accident which occurs recently5 year for is principal is The GMDSS with the formation vessel which is managed with agreement depends here upon and it is a collision of the small-sized vessel which is not managed. Cause the Facilities for the safety-communications system is not introduced is the actual condition in poverty of the small-sized vessel. In this study, recently with the AIS where becomes the introduction it proposed similar function the system which is cheap it does.
