Problems solved by technology

[0007] The purpose of the present invention is to propose a data transmission method for AIS mobile base stations, which can solve the problem that the AIS server cannot receive the AIS information of the ship when the ship is beyond the receiving range of the receiving station or sails in an area where the base station is not established

Embodiment Construction

[0025] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0026] When the number of ships equipped with AIS mobile base stations within a radius of 10-30 nautical miles is greater than 1, multiple AIS mobile base stations may receive the same ship's AIS information at the same time. At this time, multiple AIS mobile base stations will upload the ship information separately, resulting in data redundancy and waste of communication traffic.

[0027]In order to avoid this situation, it is necessary to use the data transmission method of the AIS mobile base station of this embodiment, so that the AIS terminal and the AIS server can work in coordination. It not only achieves reasonable redundancy in the actual transmission data, but also does not lose ship position information during dynamic changes.

[0028] In the system implementation of the AIS mobile base station, the short message of the Beidou satellite comm...

Abstract

The invention relates to a data transmission method for an automatic identification system (AIS) mobile base station. According to the method, a ship with an AIS terminal can obtain AIS information of an AIS device of the ship through an AIS signal interface, the AIS information is transmitted to an AIS server through a Beidou satellite communication system and undergoes uniform processing after received by the AIS server, and accordingly the ship with the AIS terminal is equivalent to the AIS mobile base station on the sea. The Beidou satellite communication system is adopted to serve as a communication mode, and the data transmission method has the advantages of communication timeliness, high frequency and low total cost. Besides, according to the method, the problem that the AIS information is uploaded repeatedly after a plurality of AIS mobile base station receives the AIS information of the same ship can be solved, uploading of plenty of redundant data is avoided, and effective utilization of a bandwidth of the Beidou satellite communication system is reinforced.

Description

technical field [0001] The invention relates to a data transmission method of a ship automatic identification system (Automatic Identification System, referred to as AIS). Background technique [0002] The BeiDou (COMPASS) Navigation Satellite System is a self-developed and independently operated global satellite navigation system being implemented by China. It is listed as the world's four major GNSS systems along with the US GPS, Russia's GLONASS and the EU's GALILEO. The Beidou regional navigation test system built in 2003, also known as the Beidou No. 1 system, can provide active positioning, timing and short message communication services (referred to as Beidou function) in China and surrounding areas; in 2012, the construction of regional navigation and positioning covering the Asia-Pacific region The system can provide passive positioning, timing and short message communication services to the Asia-Pacific region; by 2020, a global positioning system covering the whol...
