유비쿼터스 기술의 함정적용: 선원위치인식시스템

Abstract

New information and communication technologies are developing, which provide ubiquitous environment and make the ubiquitous world possible. Some of important emerging technologies, which have potential for shipboard applications, are reviewed and up-to-date developments are summarized. Shipboard application areas for utilization of the ubiquitous technology are suggested, which would enhance the operation efficiency of a ship. Application of the ubiquitous technologies for a naval ship would enhance the operation efficiency and combat efficiency of the naval ship, being supported by a system of networked computers in real time. Since a large number of crews are dwelling in a naval combatant ship, location of each crew is not always monitored even in the most critical situation, such as in the combat ready situation. Concept of the Crew Location Monitoring System is presented and preliminary architecture of the system is given. Locations of crews can be monitored by using USN (ubiquitous sensor network) technologies. An active type RFID (Radio Frequency Identification), would be distributed to, and carried by, each crew. Readers of the RFID are located at major places where crews are likely to visit. Locations of crews are monitored and displayed at computer terminals and/or handy terminals, such as PDAs. Possible areas for extended application of the crew location recognition system are suggested.
