SHIP POSITION INFORMATION PROVIDING SYSTEM BETWEEN DISPARATE COMMUNICATION MODES, CAPABLE OF SHARING SHIP POSITION INFORMATION BETWEEN SHIPS

摘要

PURPOSE: A ship position information providing system between disparate communication modes is provided to prevent ship crush by being supplied with the location information between ships having an AIS(Automatic Identification System) or using an RF radio communication terminal.;CONSTITUTION: An RF communication local terminal(110) offers first ship operation information using 900MHz band frequency. An RF communication host terminal(120) performs radio communication with the RF communication local terminal. A wireless network terminal(130) performs communication through a wireless network(180). The mobile communication terminal(140) comprises a GPS receiver. A mobile communication relay service part(150) relays the communication of the mobile communication terminal. The mobile communication relay service part offers fourth ship operation information to a ship position information providing server(200). A ship movement monitor station(170) offers the second ship operation information transmitted from a ship automatic identification system(160) to the ship position information providing server.;COPYRIGHT KIPO 2010
