Ship collision early warning system based on unmanned aerial vehicle

Abstract

The invention discloses a ship collision early warning system based on an unmanned aerial vehicle. The system includes an unmanned aerial vehicle on which a monitoring device for collecting ship navigation data is carried, the navigation data including historical tracks and speed; a movement predictor used for predicting the position and moving direction of a ship at a next moment according to thehistorical track, speed, current position and target position to which the ship is steered of the object ship, and generating a predicted track of the ship after unit time on a two-dimensional plane;a risk range generator used for generating a risk map according to the ship speed and the predicted track, the risk map representing a possible range in which the object ship possibly is after unit time and a degree of risk under a condition that other ships enter the range; and a risk analysis module used for judging the possibility of occurrence of a collision according to the crossed overlapping situation of the risk maps of different object ships. The ship collision early warning system based on an unmanned aerial vehicle is used for performing early warning about a collision of ships andreducing the possibility of occurrence of a collision in a ship-dense water area such as a port.

Description

technical field [0001] The invention belongs to the field of ship collision prediction, in particular to a ship collision warning system based on an unmanned aerial vehicle. Background technique [0002] Waterway transport occupies less land, has low investment in infrastructure, and has a large transport volume. It plays an important role in domestic and international trade. In my country's inland waterway shipping, its average cost is 4 / 7 of the railway and 1 / 10 of the road. Although affected by the financial turmoil since 2008, the shipping industry has been relatively sluggish, but it is still an irreplaceable mode of transportation in the transportation industry. Especially under the environmental protection treaty emphasizing green and low carbon, waterway transportation has advantages that other transportation methods cannot match. [0003] Because of the irreplaceability of waterway transportation, it is indispensable to pay attention to the collision of ships. On...
