Quadrotor unmanned aerial vehicle autonomous landing control system and method based on airship platform

Abstract

The invention discloses a quadrotor unmanned aerial vehicle autonomous landing control system and method based on an airship platform. The system comprises an unmanned aerial vehicle, a control terminal, the airship platform, a camera shooting acquisition module, a communication module, a power system and a sensor module; a flight control module and a positioning navigation module are arranged inthe unmanned aerial vehicle, and the unmanned aerial vehicle is connected with the control terminal through the communication module; the control terminal is located at a ground station and used for checking the state of the unmanned aerial vehicle, monitoring the flight state of the unmanned aerial vehicle and looking up flight logs, and the airship platform is used for unmanned aerial vehicle parking and comprises a frame, hook joints and parking identifiers; the camera shooting collection module is located at the bottom of the unmanned aerial vehicle and used for collecting parking marks onthe airship platform; the communication module is used for data communication in the system; the power system provides power for flight of the unmanned aerial vehicle; and the sensor module comprisesan optical flow sensor, an ultrasonic sensor and a laser sensor. The unmanned aerial vehicle can accurately land at the designated position on the airship platform.

Description

technical field [0001] The invention relates to the technical field of airship platform and unmanned aerial vehicle flight control, in particular to a four-rotor unmanned aerial vehicle autonomous landing control system and method based on the airship platform. Background technique [0002] Today, drones have become one of the most popular emerging high-tech industries. The links from research and development, manufacturing to use, management and service are becoming more and more mature. The future development prospects of my country's drone industry are very worth looking forward to. The development of the logistics industry is eager for drones to further replace human labor, and it is necessary to deliver goods more efficiently and quickly. The docking of drones and platforms has become an issue worth discussing. In 2019, the global sales volume of drones was 3.363 million units, which is a very large number and ranks among the top sales of all high-tech products. Theref...

AI Technical Summary

Problems solved by technology

[0004] At present, there are few applications of drones docking with airships, mainly in theoretical analysis, lack of small-scale experiments in practice, and because drones still have some landing problems, the main problem is low accuracy. The moment the man-machine lands, the out-of-synchronization with the shutdown of the power system will lead to a certain jump, and it is often necessary to delineate the landing area, so at this time, the help of other equipment is needed, such as an auxiliary docking device to ease the docking Timely motor drive adjustments to improve the practicability of drones
