Modularized unmanned aerial vehicle anti-shake holder system based on LoRa

Abstract

The invention discloses a modularized unmanned aerial vehicle anti-shake holder system based on LoRa. The modularized unmanned aerial vehicle anti-shake holder system comprises an anti-shake holder and a remote client, the anti-shake holder is fixed on a unmanned aerial vehicle, and realizes communication with the remote client through a LoRa communication unit; the remote client is used for selecting an operation mode of the anti-shake holder and remotely monitoring an acceleration parameter and a pose parameter of the holder at the same time; the anti-shake holder comprises an acrylic quick-release plate, a ball screw, a direct current motor, a circuit bin, a supporting block, an upper supporting frame, a lower supporting frame, a rubber ball, a connecting rod, a fixing shaft, an objective table and a brushless holder motor. The system adopts a modular design, has the characteristics of easy installation, remote control, reduction of unmanned aerial vehicle resource utilization and the like, and has a certain reference value in the field of unmanned aerial vehicle automatic control.

Description

technical field [0001] The invention belongs to the technical field of automatic control of unmanned aerial vehicles, and in particular relates to a LoRa-based modular anti-shake cloud platform system for unmanned aerial vehicles. Background technique [0002] In recent years, due to the advantages of simple and convenient operation, high reliability and simple structure of multi-rotor UAVs, multi-rotor UAVs have gradually become a popular research object for scholars at home and abroad. UAV missions are multi-elemental, and a single multi-rotor UAV cannot meet people's needs. In order to cooperate with UAVs to complete detection and other tasks, UAVs need a camera that can carry various real-time transmission cameras or other sensors. Free motion head. [0003] Although the special structure of the multi-rotor UAV has the advantages of simple and convenient operation, high reliability, simple structure and easy maintenance, there are also some problems. Although there are...

AI Technical Summary

Problems solved by technology

(1) The safety of the gimbal is poor: in the case of long-term use, the shock-absorbing ball connecting the gimbal and the drone will crack and break

During the flight, the vibration damping ball will break due to the further expansion of the crack, which cannot effectively protect the camera

(2) The vibration reduction performance of the gimbal is poor: the vibration situation of the multi-rotor UAV is very complicated, and there are multiple excitation sources with different vibration frequencies, different amplitudes, and different phases

Therefore, during use, the vibration reduction effect of the gimbal is poor

(3) The automatic performance of the gimbal is poor: because the multi-rotor UAV is greatly affected by environmental factors during the flight, the autonomous stability of the gimbal mechanical structure alone cannot meet the demand, so the automatic performance of the gimbal is poor
