Problems solved by technology

[0002] In the current field where unmanned ships are used to perform tasks, unmanned ships are used as execution terminals and mainly rely on remote terminal control. The range is limited, so it is difficult for remote operators to monitor the status of the unmanned ship throughout the process, and cannot control the unmanned ship in time, causing the unmanned ship to yaw and sink

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] figure 1 Shown is the flow chart of the present invention, comprises steps:

[0022] (1) Obtain the electronic chart of the working area;

[0023] (2) Rasterize the obtained electronic chart, and divide the grid map into a navigable area and an obstacle area according to the area where the obstacle is located;

[0024] (3) An artificial signal mark with a fixed position is set at the grid points of the navigable area of ​​the grid map, and the position coordinates of the artificial signal mark are stored in the artificial signal mark; buoy nodes are arranged on the sea surface, and the buoy nodes move with the wave motion , collect the environmental data of the surrounding sea level; use the artificial signal as the sink node, initiate networking information to the buoy nodes in the artificial signal, after the buoy node receives the networking information, cr...

Abstract

The invention provides a fixed line unmanned ship operation method. The method includes the steps of obtaining an electronic chart in a working area, rasterizing the obtained electronic chart, arranging artificial signal beacons at grid points, storing position coordinates in the artificial signal beacons, distributing buoy nodes on the sea surface of the working area, and forming a self-assemblynetwork through the artificial signal beacons and the buoy nodes. The sailing direction of an unmanned ship is modified through the artificial signal beacons, the drift distance generated by marine GPS navigation / Beidou satellite positioning is eliminated, and it is ensured that the unmanned ship is driven on a correct ship route; in addition, the self-assembly network is formed by the artificialsignal beacons and the buoy nodes, a data interaction network of the sea surface and a remote control center is established, and the state of the unmanned ship and the state of the sea surface can bemonitored in real time.

Description

technical field [0001] The invention relates to the technical field of unmanned ships, in particular to an operation method for fixed-line unmanned ships. Background technique [0002] In the current field where unmanned ships are used to perform tasks, unmanned ships are used as execution terminals and mainly rely on remote terminal control. The range is limited, so it is difficult for remote operators to monitor the status of the unmanned ship throughout the process, and cannot control the unmanned ship in time, causing the unmanned ship to yaw and sink. Contents of the invention [0003] Purpose of the invention: In order to solve the above-mentioned technical problems, the present invention proposes a fixed-line unmanned ship operation method. [0004] Technical solution: the solution of the present invention to solve the technical problem is: [0005] A fixed line unmanned ship operation method, comprising steps [0006] (1) Obtain the electronic chart of the worki...
