Intelligent sensing navigation mark equipment and early warning method thereof

Abstract

The invention relates to the technical field of navigation equipment, in particular to intelligent sensing navigation mark equipment and an early warning method thereof, and the intelligent sensing navigation mark equipment comprises an AIS receiving unit, a control unit, a compass sensor, a positioning unit and an LED warning lamp; a raspberry Pi PC and an eight-way switch on-off controller are integrated in the control unit; the AIS receiving unit receives an AIS message and forwards the message to the raspberry Pi PC of the control unit to enter a data processing flow; the AIS receiving unit is used for receiving an AIS message of a water area ship near a navigation mark, analyzing the AIS message and extracting ship coordinates and navigation speed heading information; the compass sensor is used for acquiring a navigation mark rotation angle; the positioning unit is used for acquiring a navigation mark position; and the control unit controls the LED warning lamp to work. By integrating multiple informatization technologies, navigation environment data are collected in real time, when a ship approaches, the ship can be actively warned to avoid, economic losses and navigation risks caused by collision are reduced, navigation aiding efficiency of the navigation mark at night is greatly improved, and navigation in a water area is safer.

Description

technical field [0001] The invention relates to the technical field of navigation equipment, in particular to an intelligent perception aid to navigation equipment and an early warning method thereof. Background technique [0002] As an important visual navigation facility, navigation marks play an important role in supporting water transportation, fishery, ocean development and national defense construction. With the development of the shipping industry, the traffic volume in various navigable waters has increased exponentially, and the probability of collision between navigation marks and ships has also increased. [0003] It is said that the maintenance period of the navigation mark is long at present. If the navigation mark is disabled due to a collision, it will pose a threat to the safe navigation of passing ships. The unified navigation beacon lights use point light sources at night for ship pilots to identify. When navigating in waters with large ship traffic and co...

Problems solved by technology

[0003] It is said that the maintenance cycle of the navigation mark is long at present. If the navigation mark is disabled due to a collision, it will pose a threat to the safe navigation of passing ships.

The unified navigation beacon lights use point light sources at night for ship pilots to identify. When navigating in waters with large ship traffic and complex background light, it is often difficult to find the exact position of the navigation beacon, resulting in frequent accidents of ships colliding with the navigation beacon.

Once the buoy is hit and disabled, it will not only cause economic losses to the buoy maintenance unit, but also bring great navigation risks to the sailing ships
