Embodiment Construction

[0036] The present invention will be described in detail below according to the accompanying drawings.

[0037] The formation light show system is mainly composed of three parts: the quadrotor aircraft unit performing formation flight missions, the host computer for data monitoring and command sending, and the communication system connecting the aircraft and the host computer.

[0038] Such as figure 1 As shown, the quadrotor unit consists of three parts: mechanical frame, power structure and control system.

[0039] The main body of the mechanical frame is the frame, which serves as the mechanical hardware carrying the power structure device and control device.

[0040] The power structure includes electronic governor, motor, battery and propeller, etc. The electronic governor receives the PWM wave from the flight controller, calculates the speed of the motor, and supplies the corresponding voltage to the motor to make the motor rotate and drive the propeller on the motor R...

Abstract

The invention discloses a four-rotor aircraft outdoor formation light performance system and a control method thereof. Aircraft hardware setup, control test, host computer compiling and communicationlink design are included, and a main purpose is to conduct formation flight light performance. The position of an aircraft cannot be measured accurately in the outdoor environment, so that the methodprovides practical application measures to eliminate influence of position errors for a flight performance and avoid track generation during formation change during the performance.

Description

technical field [0001] The invention relates to the field of aircraft clusters and formations, in particular to an outdoor formation light show system and control method for quadrotor aircraft. Background technique [0002] Formation swarm systems of quadrotors have many advantages over individual robotic systems, such as redundancy and the system's inherent parallel processing structure, which can be made more reliable by relying on collective knowledge of goals. [0003] With the emergence of more and more consumer-grade drones with small multi-rotor aircraft as the main structure in the consumer market, the use of quadrotor aircraft has also shifted from industrial applications to personal entertainment. They are used in large quantities. Aerial photography, selfie and film and television shooting, or assisting some cultural and artistic performances. A micro-aircraft with autopilot can automatically follow people in motion and record their movements on video. When film...
