Multi-airport preferential take-off and landing method for vertical take-off and landing fixed-wing unmanned aerial vehicle

Abstract

The invention discloses a multi-airport preferential take-off and landing method for a vertical take-off and landing fixed-wing unmanned aerial vehicle, which comprises a fixed-wing unmanned aerial vehicle and multiple airports for taking off and landing of the fixed-wing unmanned aerial vehicle, and a sensor and an RTK space positioning module are mounted on the fixed-wing unmanned aerial vehicle. The current space coordinates of the fixed-wing unmanned aerial vehicle and the space coordinates, the speed, the course angle and the altitude of a nearby free airport in the flight process of the fixed-wing unmanned aerial vehicle are obtained in real time, the deceleration cost, the height reduction cost, the distance cost and the angle cost are calculated, and the total airport cost is the sum of the deceleration cost, the height reduction cost, the distance cost and the angle cost; and the total cost of each airport is calculated, the airport with the minimum total cost is the optimal landing airport. The effective operation time of the unmanned aerial vehicle can be effectively prolonged, the operation radius is increased, the optimal airport landing is selected through calculation according to the flight state of the unmanned aerial vehicle, the dependence of the fixed-wing unmanned aerial vehicle on the airport is reduced, the burden of operators is greatly relieved, and the working efficiency of the fixed-wing unmanned aerial vehicle is improved.

Description

Technical field: [0001] The invention relates to the field of unmanned aerial vehicle research, in particular to a multi-airport selective take-off and landing method for a vertical take-off and landing fixed-wing unmanned aerial vehicle. Background technique: [0002] With the rapid development of UAV technology, the application of UAV is becoming more and more extensive. Due to the characteristics of small size, light weight, high cost performance, flexible operation and high safety, it is widely used in communication relay, environmental monitoring and forest fire prevention. , power inspection, geological survey, aerial photography and other fields play an important role, and the performance of drones has also been significantly improved. According to the flight principle and structure of drones, they can be roughly divided into fixed-wing drones and multi-rotor drones. Fixed-wing UAVs have a great advantage in the field of UAVs due to their structural advantages and ad...

Problems solved by technology

[0003] However, drones are restricted by battery density, and the time to stay in the air is limited. The inspection range is small, the battery consumption is large, and the degree of automation is low. However, inspection operations often fly along point-like power, taking off and landing at the same place It will consume a lot of flight time and battery power, and it will not be able to carry out long-distance, large-scale, long-term uninterrupted patrols, and cannot meet reliability requirements, which will greatly reduce operating efficiency and put pressure on operators
