SHIP'S INTERNAL COMMUNICATION SYSTEM

摘要

The present invention relates to an intra-vessel communications apparatus, which satisfies a convention of a safety of life at sea (SOLAS) without the communications device duplex and compartment constitution in a vessel. The intra-vessel communications apparatus comprises: an internal ultra high frequency (UHF) antenna cable individually installed in a plurality of maximum fire zones (MFZ) divided with respect to a firewall so as to transmit a wireless signal; a wireless signal distributor for transmitting a wireless signal received through the internal UHF antenna cable, and receiving the wireless signal transmitted from other MFZs to transmit the same to the internal UHF antenna cable; and a wireless signal repeater for receiving and amplifying the wireless signal obtained by the wireless signal distributor, and spreading the amplified wireless signal to the MFZs. The internal UHF antenna cable is installed in the MFZs along a cable tray installed in each MFZ.
