Problems solved by technology

However, in some special fields, such as the field of monitoring unmanned ships, traditional unmanned ships rely on diesel or batteries as energy sources, and cannot work in the ocean for a long time
At the same time, traditional communication methods, such as ASI, cannot meet the growing monitoring requirements
When there is no autonomous communication satellite in our country, the unmanned ship cannot realize the two-way transmission of voice and data, and cannot meet the requirements of remote sea operations
The result of the lack of effective monitoring of the distant seas is that my country's rights and interests in the distant seas cannot be guaranteed, resulting in resource losses and economic losses.

Embodiment Construction

[0028] The present invention will be further described below in conjunction with specific examples and drawings.

[0029] The present invention provides a method for controlling a remote unmanned sailing vessel in a fixed area, such as figure 1 As shown, it includes the following steps:

[0030] S1. Route planning through electronic chart and route planning unit. Specifically, Beidou navigation is used to obtain the navigation point of the unmanned ship on the electronic chart, and then the binary tree route planning algorithm and the A-star route optimization algorithm are used for route planning.

[0031] S2. Collect the current wind and wind direction in real time, specifically use the wind direction sensing unit to detect the current wind direction, and the wind sensing unit monitors the current wind pressure P in the wind direction.

[0032] S3. Determine the current required course and speed according to the planned route, calculate the set windward angle of the sail at this tim...

Abstract

The invention provides a control method for a long-distance and fixed-area sail unmanned ship, which comprises the steps of carrying out route planning through an electronic sea chart and a route planning unit; determining the current required course and speed according to a planned route, calculating the set windward angle of the sail at the time by combining the collected wind direction, and then calculating the required set unfolding area according to the wind force; controlling a sail rotating mechanism to rotate the sail according to the set windward angle, and controlling a lifting mechanism to unfold or fold the sail according to the set unfolding area; collecting the actual windward angle and the actual unfolding area of the sail in real time, comparing the actual windward angle and the actual unfolding area with the set windward angle and the set unfolding area respectively, and carrying out real-time compensation if there is deviation; and starting the collection of environmental data under a control instruction in the cruising process, and transmitting the collected data to a ground control station through the Tiantong satellite. The control method improves the continuous working ability and complex data transmission ability of the unmanned ship in the ocean through utilizing the wind energy and Tiantong satellite communication platform.

Description

Technical field [0001] The invention relates to the technical field of unmanned ship control, in particular to a method and system for controlling an unmanned ship with long-distance sailing in a fixed area. Background technique [0002] The unmanned ship is called "surface robot", it is a kind of water robot that does not need manned to operate, through remote control, or even without manipulation, it can sail and perform tasks autonomously. It is more suitable for performing dangerous or boring, repetitive military and civilian tasks, such as military strikes, security patrols, landform mapping, environmental monitoring, emergency rescue and other fields. [0003] At present, with the improvement of the world's technological level, mankind has developed a large number of unmanned products, taking full advantage of their safety, low cost, and easy maintenance to replace a lot of manual labor and improve social production efficiency. In the shipbuilding industry, the emergence of ...
