Offshore search route planning method for large amphibious aircraft

Abstract

The invention belongs to an aircraft route planning technology, and particularly relates to a planning method for route coverage of a fixed area by a large amphibious aircraft. The offshore search route planning method for the large amphibious aircraft comprises the following steps of, firstly, inputting map information and ocean current information of a search area; secondly, dividing the continuous irregular map region into discrete and communicated grid regions; determining the initial position and speed of the aircraft; taking the connected domain grid with the optimal performance index asa next search target grid point according to a grid performance index formula, sequentially calculating the next search target grid point until the grid point with the optimal overall performance index is selected to trace back the source track to obtain the optimal search track in the grid, and correcting the search track according to the interference information to obtain the optimal search track of the sea area. By means of the method, the optimal search path can be quickly solved, all search tasks are completed at the fastest speed and the shortest voyage, and support is provided for offshore low-cost efficient search of the large amphibious aircraft.

Description

technical field [0001] The invention belongs to aircraft route planning technology, in particular to a planning method for a large amphibious aircraft to cover a fixed area. Background technique [0002] The sea search route planning problem is a kind of coverage route problem. The coverage route problem is commonly found in robot area coverage, UAV route planning and plant protection helicopter route planning. However, the above route planning technologies mostly cover fixed small-scale areas. . The sea search has a long range, tight time, wide search area, and changes in the search area due to the influence of ocean currents and wind fields, so the traditional route planning method is difficult to meet the requirements of sea search route planning for large amphibious aircraft. [0003] At present, the existing technology lacks a route planning method for large-scale amphibious aircraft. Therefore, it is difficult for large-scale amphibious aircraft to determine the optim...

AI Technical Summary

Problems solved by technology

The sea search has a long range, time is tight, and the search area is wide. The search area is affected by ocean currents and wind fields. Therefore, the traditional route planning method is difficult to meet the requirements of large-scale amphibious aircraft sea search route planning.

[0003] At present, the existing technology lacks a route planning method for large-scale amphibious aircraft. Therefore, it is difficult for large-scale amphibious aircraft to determine the optimal search path when participating in sea searches. It is economical and fast to cover the search area, and is easily affected by interference factors such as ocean currents, reducing the search effect.
