Problems solved by technology
On the one hand, this will increase the cost of the ship's employment, and on the other hand, there will be a risk of collision accidents caused by the misoperation of the two ships that meet the ship.
Especially in the event of an emergency, ineffective communication between ships will increase the risk of accidents

The invention relates to the field of ship communication, in particular to a ship automatic identification selective calling method and system. The method is applied to at least one request end and at least one response end. The method specifically comprises the steps that S1, a request end receives first self-identification information broadcasted by a response end in advance, generates corresponding second self-identification information and sends the second self-identification information to the response end so as to establish communication connection between the request end and the response end; and S2, the request end sends the first very high frequency signal to the response end and receives a second very high frequency signal sent by the response end so as to carry out communication between the request end and the response end. The beneficial effects of the technical scheme of the invention are that the ship automatic identification selective calling method, device and system are provided, communication connection is established by using self-identification information, and communication is performed by using very high frequency signals, so that channel congestion is reduced, call quality is improved, and safe navigation of the ship is guaranteed.
Description
Technical field [0001] The present invention relates to the field of ship communications, and more particularly to a ship automatically identify the calling method and system. Background technique [0002] In the prior art, there is often used very high-frequency ship radio equipment in the ship communication, VHF (Veryh Frequency, very high frequency) ship station operating frequency segment is divided into 57 channels, and two radio stations in the same channel can be carried out. Communication. The communication service of the VHF ship radio includes voice calls and DSC (DigitalSelective Calling Terminals, number choice). When communication between two boats, you need to communicate through the DSC, coordinate the communication channel, the crew adjusts the DSC information to adjust the radio channel, so that the two ships are in the same channel, and then perform voice communication. This process of establishing communication is high for crew, and specialized trainers can be ...
