Intelligent sensing navigation mark device based on AIS and early warning method thereof

Abstract

According to the AIS-based intelligent sensing navigation mark equipment and the early warning method thereof, switching between an entity AIS navigation mark and a virtual AIS navigation mark can be intelligently selected according to whether the sea surface environment is suitable for navigation mark equipment operation or not; according to the navigation mark, the navigation mark light is combined with the virtual AIS navigation mark to navigate the passing ships, the ship provided with the AIS system and the ship not provided with the AIS system can still be navigated according to the navigation mark light, the navigation mark is located in the calm seabed under the severe weather condition, the navigation mark is clamped and fixed through the relay floating body, and the navigation effect is good. And meanwhile, the energy storage winding drum structure is used for achieving winding and unwinding of the mooring rope, and power output of a motor, hydraulic pressure and the like is not needed for winding and unwinding of the navigation mark creatively.

Description

technical field [0001] The invention relates to the field of marine equipment, in particular to an AIS-based intelligent perception aid to navigation equipment and an early warning method thereof. Background technique [0002] A navigation mark is a sign indicating the direction, boundaries and obstacles of a channel. It is a navigational aid to mark the channel and guide the navigation of ships. It is an important guarantee for the safety of shipping. The automatic identification system (Automatic Identification System) is composed of shore-based (base station) facilities and ship-borne equipment. It uses radio wave propagation, and the positioning data comes from the global navigation satellite system GNSS (Global Navigation Satellite System). Its work is not affected by distance, The influence of position, more importantly, is almost not limited by meteorological conditions. Therefore, AIS is widely used in both ships and navigation marks. In the prior art, such as Paten...

AI Technical Summary

Problems solved by technology

[0006] To sum up, in the existing technology, either a single virtual AIS navigation mark or a single real AIS navigation mark is used, which does not take into account the problems of inaccurate measurement and data update delay of the virtual AIS navigation mark, nor does it take into account the reality AIS aids to aids are easily damaged or blown away when encountering bad weather. Therefore, there is no aid to aids system that takes into account the combination of real AIS aids to aids and virtual AIS aids to aids, and does not provide a way to Even if a kind of buoy that can sink is provided, the buoy that can resist bad weather is better, and its sinking is to use a reel structure with a power source to retract, and even after sinking, the buoy does not have a The fixing device is fixed, and it is easy to be affected by the water flow and swing from side to side or swing to cause damage to the internal electronic components. An AIS-based intelligent perception aid-to-navigation device and its early warning method that sinks the aid of navigation under water, can sink without using a motor, and can still be recognized by radar after being weighed down
