Problems solved by technology

[0009] Aiming at the problem that the effective coverage range of the AIS system signal in the prior art is limited by the distribution of shore-based stations, resulting in the coverage of AIS signals in some sea areas, the present invention provides an AIS system based on Beidou short message, and its purpose is to: Enable the ship to send the AIS information of the ship and receive the AIS information of other ships at any position, to ensure the safety of life and property of the people on the ship

Embodiment 1

[0046] During the voyage, if the ship A is about to sail to a narrow intersection, in order to prevent the ship from colliding during the voyage, the ship A now writes the short message to be sent through the AIS information processing module 1 in a custom way, The short message includes the ship's position, speed, heading, ship name, call sign and other information of the ship A; after it is written, it will be sent to the BDS chain 10 through the BDS system short message sending module 2, and the BDS chain 10 will send it to the whole network. This short message can be parsed after receiving the message. Now ship B has received this short message through the short message receiving module 3 of the Beidou system, and the AIS information processing module 1 interprets the short message, and interprets the ship's position, speed, heading, ship name, call sign and other information of ship A. At this time, the B ship can send information such as the ship's position, speed, cours...

Embodiment 2

[0048] Ship C leaked water and could not be repaired. The short message to be sent was compiled through the AIS information processing module 1. The short message included the ship's position, speed, course, ship name, call sign and distress situation of the ship C; The system short message sending module 2 sends it to the Big Dipper chain 10, and the Big Dipper chain 10 sends it to the whole network. After receiving the message, ships within the coverage area can analyze the short message. The nearby ships have analyzed the relevant situation and can quickly approach for rescue, so that rapid rescue can be realized.

Embodiment 3

[0050] A certain sea area is monitored through Beidou satellites, assuming that there are 100 ships in the monitoring screen, 60 of which are domestic ships. Since the system is installed on all domestic ships, these 60 domestic ships communicate with Beidou Starlink 10 through Beidou short messages, and Beidou satellites mark the ships that communicate with them, and those that do not communicate with Beidou satellites are foreign ships. Next, the Beidou satellite only needs to monitor the remaining 40 ships that do not communicate with it, which can greatly reduce the difficulty of monitoring and is conducive to national security.

Abstract

The invention discloses an AIS (Automatic Identification System) based on Beidou short messages, belongs to the technical field of ship navigation safety guarantee, and solves the problem that AIS signals in some sea areas cannot be covered due to the fact that the effective signal coverage range of the AIS is limited by shore base station distribution in the prior art. Meanwhile, the invention provides a new method for effectively identifying the identity of the suspicious ship in a sensitive sea area. The system comprises a Beidou system short message sending module, a Beidou satellite chain, a Beidou system short message receiving module, a Beidou system navigation information receiving module, an AIS information processing module and a power supply module. Short message interaction isdirectly carried out among the Beidou system short message sending module, the Beidou satellite chain and the Beidou system short message receiving module, information interaction does not need to becarried out through a base station, and the problem that the effective signal coverage range of an existing AIS system is limited by shore-based station distribution is solved. The AIS system is suitable for sending and receiving the AIS information of the ship.

Description

technical field [0001] The invention belongs to the technical field of ship navigation safety guarantee, and in particular relates to an AIS system based on Beidou short message. Background technique [0002] Ships and ships sailing on water will cause marine accidents due to grounding, collision, typhoon, capsizing, fire, accidental explosion, toxic gas leakage, and personnel falling into the sea. [0003] In actual voyages, ships are prone to failures at sea, that is, equipment failures, inability to sail, or sailing will deviate from the route, etc. In this case, there will be the following problems. If the ship is on the high seas, the ship cannot sail. The communication equipment can only ask for help in one direction, and it will not know in time which rescue ships are around, which will prolong the rescue time and increase the risk of people on the rescued ship; if the ship sails, it will deviate from the route, because it cannot be known in advance The speed or posi...
