The traditional Aids to Navigations(AtoN) have been ensuring the safety of ships by indicating the passage and dangers by depending on the flashing lights. But the more the industrial complex behind port which is all over the country involving the Ulsan port developed, the more the lights behind port is stronger, and then the distinguishment of the signal of AtoN from the lights behind port is more difficult. And It is urgently needed to prepare the counterplan about the ensurement of safety because the authorities levels up the limit tonnage of the ships which are sail in and out during night to improve the operation of port through reducing of the traffic jam So, the method of direct lighting like LED non-neon is applied to unmanned lighthouses or light beacon, and the LED flashing number plate is applied to light buoys whose light power is weaker than to improve distinguishment and to be easy positioning of ships. As a result, the users of Ulsan port comment favorably on this item and the development of AtoN must be continuos to overcome the lights behind port.

This study is the visually identification lighting for easy to distinguish using colors LED on AtoN facility in harbor gate, which have realized a controller for certainly express the gate of harbor by red light and green light of both sides a harbor and for synchronization at a time of right and left or sequential the harbor guidance light through synchronizer or timer by GPS. There is expectation effect that is prevent a confusion about distinguish of facility by ship's operator and to beautify a night scene of harbor, which is expressed to identification lighting differ from great many lighting of harbor with variable color lighting the lighthouse body and vertical layer color lighting using LED. Especially the function of AtoN is displayed for harbor safety message by CW lighting, and this system is the power consumption greatly reduce by candle alternated high light LED.

In line with future changes in the marine environment, Aids to Navigation has been used in various fields and their use is increasing. The term "Aids to Navigation" means an aid to navigation prescribed by Ordinance of the Ministry of Oceans and Fisheries which shows navigating ships the position and direction of the ships, position of obstacles, etc. through lights, shapes, colors, sound, radio waves, etc. Also now the use of Aids to Navigation is transforming into a means of identifying and recording the marine weather environment by mounting various sensors and cameras. However, Aids to Navigation are mainly lost due to collisions with ships, and in particular, safety accidents occur because of poor observation visibility due to sea fog. The inflow of sea fog poses risks to ports and sea transportation, and it is not easy to predict sea fog because of the large difference in the possibility of occurrence depending on time and region. In addition, it is difficult to manage individually due to the features of Aids to Navigation distributed throughout the sea. To solve this problem, this paper aims to identify the marine weather environment by estimating sea fog level approximately with images taken by cameras mounted on Aids to Navigation and to resolve safety accidents caused by weather. Instead of optical and temperature sensors that are difficult to install and expensive to measure sea fog level, sea fog level is measured through the use of general images of cameras mounted on Aids to Navigation. Furthermore, as a prior study for real-time sea fog level estimation in various seas, the sea fog level criteria are presented using the Haze Model and Dark Channel Prior. A specific threshold value is set in the image through Dark Channel Prior(DCP), and based on this, the number of pixels without sea fog is found in the entire image to estimate the sea fog level. Experimental results demonstrate the possibility of estimating the sea fog level using synthetic haze image dataset and real haze image dataset.

The high tech marine transportation infrastructure is an innovative that may be able to secure a safe transportation environment. The current sea route sign system based on an electronic marine chart only has a data manufacture specification for uses at ECDIS. Therefore, it has a limitation in expressing various sea route data and falls short of productivity as it is frozen to prevent being changed for a long time. Also, it cannot satisfy requirements from high tech such as lattice structure data and time series information. Currently, although it builds each independent operation system based S-57, it has been found that it is the most important requirement from consumers that the entire monitoring system can mutually interwork by standardizing and uniting formats of all protocols. In addition, current status information and alarm system is using AIS, TRS, WCDMA telecommunication and processing all the data after saving it into each different server. In this thesis, we will realize the status information and alarm system of Marine transportation facilities which is a sea route sign system based on S-63 electronic marine chart, S/W, after uniting each different protocol and making combined system.

The Lighthouses and light beacons are representative structures of Aids to Navigation(AtoN) facilities. Incheon had been the region where they were constructed actively in early moden era. This study is targeting the lighthouse and light beacon which are managed by Regional Maritime Affairs. They will be organized by the research from field investigation. And conservation and management method for long-term preservation on the objects that has cultural and historical values will be suggested through this study.

파력발전은 파도의 운동에너지와 위치에너지를 전기에너지로 변환하는 발전 방식을 사용하여 무한한 에너지원으로 친환경적이다. 기존에 있는 파력발전기는 대체적으로 큰 전기에너지를 생산하며 이 에너지를 이용하기 위해서는 큰 시설물과 대형 발전기 등이 중심이 되어있다. 항로표지와 같은 해양안전유도시설은 비교적 큰 에너지 보다는 적은 에너지원을 필요로 하기에 기존의 파력에너지와의 접근이 용이하지 않는다. 별도의 시설물 없이 작은 파도에서도 위치의 변화에 따라 전기에너지를 생산하는 방식의 Motion Generator를 연구하였다.

Advances in IT technology and modernization of AtoN(Aids to Navigation) facility has increased the unmanned operation of AtoN. However, in AtoN facilities, accessibility is low and it is not able to perform maintenance on the bad weather at the time. In connection with this, in this paper, by applying the protocol of the enhanced dual LED marine lantern, we implemented the short-range monitoring system for a mobile terminal. System implemented in this paper can be carried out confirm the operation status, inspection or control of the dual LED marine lantern at a short distance. Also, it is possible to reduce maintenance costs and prevent accidents during inspection of AtoN. At the same time, it enables the operation test easily without disassembling the product, effective AtoN operation is possible. We tested the system that has been implemented using prototype of the LED marine lantern and confirmed state informations and controlled the behavior of the system in real time.
