저전력 항행지원 AIS 시스템 구현 및 성능평가에 관한 연구
|dc.description.abstract||Abstract As the international trade is increased, the marine transportation is more complex these days. In spite of the navigation radar that is installed on the ship, the ship accidents like collisions of ships, ship's stranding are continued. Therefore, IMO revised the SOLAS to adopt the rule that mandates IMO contract ships have to install AIS after 7th July 2002. AIS is to support the ships to get the maritime safety, efficient navigation, and to protect the maritime environments. AIS can communicate from ship to ship, ship to shore through the static information like IMO number, call sign, Ship name, length and width of the ship and etc., and dynmic information like location, speed, destination and etc. of the ship. AIS transmit the information of the ship on the VHF channel(161.975MHz, 162.025MHz) by using SOTDMA(Self-Organized Time Division Multiple Access) method. AtoN AIS is to be installed on the shore or navigation aid, such as buoy, lighthouse etc. because it is very difficult to support the power required to the AtoN AIS with the power. So, it need the mechanism which can implements the low powered system. Now, Navigational Aids usually use the solar energy or batteries. Because it need water-proof constriction and meet the environment conditions. no way to supply the power from commercial power source. The electronic navigation system based on the AtoN AIS can directly transmit the information related to navigation or weather to the ships traveling near sea. All information acquired from the AtoN AIS can be used usefully. because it has the various kinds of merits like the compatibility between the equipments on standard protocol. This propose the design can accommodate the transmit, receive, power, and interface module on one board. After that implement the AtoN AIS, because there is exist proved the quality of the system meet to the international and domestic technical regulations. In addition to the design and implementation it was evaluated the basic performance compare to the equipment. introduced by other countries. also. main functions such as monitoring and controlling navigation aids was tested.||-|
