Problems solved by technology

[0004] For the above-mentioned invention patents, although the wave glider has a certain detection capability, because the wave glider transceiver antenna is close to the sea level, the AIS has a limited range of action, which is only about a few hundred meters in bad sea conditions. When the target is found It will be too close to dodge in time, and the success rate of collision avoidance is low
Moreover, the algorithm of the process of analyzing and processing the target ship and making collision avoidance decisions is complex and the amount of calculation is large. Implementation on the wave glider will increase hardware costs and power consumption

Embodiment 1

[0045] Embodiment 1 is basically as attached figure 1 Shown:

[0046] The collision avoidance steps are divided into S1, S2 and S3.

[0047] S1: Obtain the AIS information sent to the Internet by ships in the preset area;

[0048] The wave glider communicates with the satellite through the satellite communication device during navigation. The ground station communicates with the satellite to receive the information returned by the wave glider in real time. The returned information includes the real-time position information of the wave glider. The ground station glides according to the wave The real-time position information of the wave glider, obtains the AIS information sent to the Internet by other ships on the Internet, and records the information of the ships within a radius of 8 kilometers of the wave glider. The ship information includes the coordinates, course and route of the ship.

[0049] The process of obtaining ship information is as follows, such as figure 2 As...

Embodiment 2

[0064] Embodiment 2 is basically as attached figure 1 Shown:

[0065] The basic principle of embodiment 2 is the same as that of embodiment 1, and the difference is that in embodiment 2, R is equal to 15 kilometers. The advantage of doing this is to obtain ship information in a larger area, to avoid collision of ships in a larger range, and to improve the speed of avoidance. touch success rate.

Embodiment 3

[0066] Embodiment 3 is basically as attached figure 1 Shown:

[0067] The basic principle of embodiment 3 is the same as that of embodiment 1. The difference is that in embodiment 3, when the coordinate point of the ship is used for collision avoidance, when the distance from the ship to the heading direction of the wave glider is greater than 3 kilometers, no collision avoidance operation is performed, and it is less than 3 kilometers. Carry out collision avoidance operation. The advantage of doing this is to stay away from stationary ships as much as possible and reduce the possibility of collision with stationary ships.

Abstract

The present invention relates to the technical field of wave glider collision avoidance, in particular to a low-cost wave glider maritime collision avoidance method. The wave glider communicates with the ground station through satellites, and the ground station receives the information returned by the wave glider. S1: Acquisition AIS information sent to the Internet by ships in the preset area; S2: According to the ship information and wave glider coordinates, classify the ships into safe ships and ships with collision risk; S3: According to the AIS information of ships with collision risk, Carry out collision avoidance according to the preset avoidance operation. The method does not need to install collision avoidance equipment on the glider, reduces the power consumption of the glider, and the wave glider can avoid collision of ships at a long distance.

Description

technical field [0001] The invention relates to the technical field of collision avoidance of a wave glider, in particular to a method for avoiding collision of a low-cost wave glider at sea. Background technique [0002] The wave glider is a new type of unmanned offshore platform that uses wave undulations to convert wave energy into forward kinetic energy. The wave glider needs to operate in the ocean environment for a long time and in a large area, and it needs to have certain collision avoidance capabilities to avoid collisions with other aircraft during navigation. However, the wave glider is limited by space and energy, and it is equipped with radar, laser There are certain difficulties in waiting for collision avoidance equipment. [0003] In order to solve the above problems, the Chinese patent publication number: CN111591404A discloses a collision avoidance method for a wave glider. The method includes a collision avoidance detection system. There is an AIS receiv...
