Multi-rotor unmanned aerial vehicle and telemetry and telecontrol method

Abstract

The invention provides a multi-rotor unmanned aerial vehicle and a telemetry and telecontrol method to overcome the defects of multi-rotor unmanned aerial vehicles in aspects of positioning and obstacle avoidance at present. The multi-rotor unmanned aerial vehicle comprises a mobile terminal and a terminal, wherein the mobile terminal comprises a mobile terminal central processing unit, a mobile terminal positioning module, a mobile terminal data transmission module, a mobile terminal memory module, a PTZ (pan-tilt-zoom) control module, a flight control module and a radar ranging module; the terminal comprises a terminal central processing unit, a terminal data transmission module, a terminal data forwarding module and a terminal memory. The telemetry and telecontrol method comprises four steps. The multi-rotor unmanned aerial vehicle and the telemetry and telecontrol method have the benefits as follows: the radar ranging module is added to detect distances between the unmanned aerial vehicle and obstacles in real time, so that the unmanned aerial vehicle is effectively prevented from having accidents when encountering the obstacles. A historical positioning information reading method is adopted, and the aerial vehicle can return to starting positions according to historical routes in case of positioning information abnormities.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a multi-rotor unmanned aerial vehicle and a telemetry and remote control method. Background technique [0002] The rotor unmanned aerial vehicle is an advanced vertical take-off and landing micro-autopilot unmanned aerial vehicle system. It is suitable for departments such as firefighting, transportation, public security and police technical investigation. Various aerial missions such as tracking and real-time intelligence gathering. [0003] Unmanned aerial vehicles have many advantages such as small size, flexible maneuverability, simple operation, convenient maintenance, convenient portability, reliability and high cost performance. In addition, they also have all-terrain take-off and landing capabilities and are highly intelligent. They can fly in various attitudes, such as hovering , forward flight, side flight and inverted flight, etc., have sp...

AI Technical Summary

Problems solved by technology

[0004] Existing multi-rotor unmanned aerial vehicles are very dependent on positioning information. When the positioning information is abnormal, the unmanned aerial vehicle cannot know where it is, resulting in abnormal flight, and some may even fall

On the other hand, unmanned aerial vehicles generally fly at a low altitude, and there are many buildings above the city. It is difficult to effectively solve the problem of obstacle avoidance only through human operation, and the adaptability to the environment is poor.
