Description

Port ship communication device

Technical Field

The utility model belongs to the technical field of the wisdom harbour, especially, relate to a harbour ship communication device.

Background

VHF is an abbreviation of Very High Frequency, which means radio waves in the Frequency band from 30Mhz to 300MHz, and has a wavelength range of 1m to 10 m. Most of them are used as broadcasting of radio and television stations and communication channels of aviation and navigation.

The VHF (very high frequency) intercom equipment for the ship is radio communication equipment which adopts a VHF special frequency band to carry out communication among ships, inside the ships, between ships and shore or between the ships and onshore users which are in communication transfer with land through a shore station, is widely applied to the aspects of ship avoidance, maritime management, port production scheduling, internal management of the ships, rescue in danger, safety information broadcasting and the like, and is a main means for completing communication on site in water traffic. The important role of VHF communication in ensuring the safety of ship navigation cannot be replaced by other modes of communication.

At present, a single VHF communication device is still adopted for communication between a ship and a port, and when the VHF communication is not smooth, another communication mode cannot be selected.
