Problems solved by technology

[0003] However, the existing information-based buoys still fail to meet the needs of navigators for high-quality services
The traditional control method used for information buoys has low control accuracy, poor anti-interference ability, and is greatly affected by the external environment. Once encountering bad weather, it may cause the buoy to fail to transmit relevant information in time, or fail to Timely adjust the buoy positioning to deviate from the channel, reducing the navigation aid effect of the buoy

Embodiment Construction

[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0059] Buoys are important facilities to ensure the safe navigation of ships at sea. They provide visual signals for ships at night or in harsh conditions such as fog and cloudy days, and provide safe navigation for ships at sea. It usually consists of buoys, towers, mooring systems, navigation equipment and power systems. Most of the buoys are large buoys, the diameter of the buoy is generally greater than 10m, and they are arranged on both sides of the channel. W...

Abstract

The invention discloses an omnidirectional positioning buoy control method based on a fuzzy algorithm. The method comprises the following steps: acquiring position information of a buoy; calculating aflight path deviation value and generating a course instruction for eliminating the flight path deviation value by comparing the position information with planned flight path information, wherein thecourse instruction comprises a command course and a set speed obtained by taking the track deviation value as an input value and calculating through a fuzzy algorithm; acquiring the actual heading and the actual running speed of the buoy; according to the actual course, the command course, the actual running speed and the set speed, calculating a control quantity by utilizing a PID algorithm; anddriving the buoy to move to a specified position of a planned route according to the control quantity. The invention provides an omnidirectional positioning buoy control method, system and equipmentbased on the fuzzy algorithm, which can improve the correction performance of self-tuning control and improve the control precision, so an ocean buoy can quickly correct track deviation and realize accurate positioning.

Description

technical field [0001] The invention relates to the technical fields of electronic information and positioning buoys, in particular to a fuzzy algorithm-based omnidirectional positioning buoy control method, system and equipment. Background technique [0002] Traditional buoys include visual buoys, radio buoys, acoustic buoys, etc., which are the basic part of buoys and provide indispensable navigational information for safe navigation of ships. Modern buoys are "data buoys" or "information buoys" that integrate information technology and buoy technology. On the basis of traditional buoys, electronic information data or independent information sources independent of the buoy logo are added, so that the buoy has navigation information other than the buoy logo. Through data collection, encoding and broadcast communication or network transmission, electronic buoys provide more navigation aid information to ships. At the same time, ship navigation regulatory agencies obtain in...
