Problems solved by technology

[0007] The purpose of the present invention is to propose an AIS mobile base station system based on the Beidou satellite communication system, which can solve the problem that the AIS server cannot receive the AIS information of the ship when the ship exceeds the receiving range of the station or sails in an area where the base station is not established

Embodiment Construction

[0029] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0030] Such as figure 1 As shown, the AIS mobile base station system based on the Beidou satellite communication system includes AIS equipment installed on each ship, an AIS terminal installed on at least one ship and an AIS server installed on land. For example, ships 1 to ship n, ship m, and ship x in this embodiment are all equipped with AIS equipment. The AIS equipment in this embodiment is the same as the prior art, and has the ability to receive AIS information broadcast by other ships other than the own ship and to broadcast the AIS information of the own ship. capacity for information. AIS terminals are also respectively installed on the ship m and the ship n. Ship 1 to ship n are within 10-30 nautical miles of ship m, and ship n is within 10-30 nautical miles of ship x.

[0031] Such as figure 2 As shown, taking ship m as an example for il...

Abstract

The invention relates to an automatic identification system (AIS) mobile base station system based on a Beidou satellite communication system. A ship with an AIS terminal can be enabled to acquire the AIS information of an AIS device of the ship through an AIS signal interface, the Beidou satellite communication system is used for enabling the AIS information to be transmitted to an AIS server, and the AIS server processes uniformly after receiving. Thus, the ship with the AIS terminal is equivalent to an AIS mobile base station on the sea. The Beidou satellite communication system is used as a communication mode, the maximum effects of communication timeliness and high frequency are achieved, and the advantage of being low in total cost is also achieved. The AIS server can achieve the fact that the AIS information is updated in 3-10 minutes.

Description

technical field [0001] The present invention relates to a ship automatic identification system (Automatic Identification System, referred to as AIS), in particular to an AIS system based on the Beidou satellite communication system. 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 r...
