Split-type all-terrain multi-rotor aircraft with anti-collision function

Abstract

The invention provides a split-type all-terrain multi-rotor aircraft with anti-collision function, the rotor assembly is divided into a longitudinal main rotor and a lateral auxiliary rotor, the longitudinal main rotor is used for lift control, and the lateral auxiliary rotor is used for flight direction and attitude control , and assist the longitudinal main rotor to provide lift; the middle connecting plate limits the degree of freedom of the system roll, the aircraft roll inertia and yaw inertia are relatively large, and the conversion of the yaw degree of freedom into the pitch and yaw control of the whole aircraft can improve the stiffness of the system, and Improve control reliability. The DC brushless motor and rotor components of the aircraft are included in the upper protective cover, and the camera drive motor, camera, control system and battery are all included in the lower protective cover. The upper protective cover and the lower protective cover provide comprehensive protection for the system. The aircraft of the invention is not limited by the environment, has all-terrain flight capability, and has wide application prospects in dangerous fields such as field cave exploration, indoor inspection of burning buildings, leakage of dangerous chemical products and radioactive substances, and the like.

Description

technical field [0001] The invention relates to intelligent control and Lora communication technology, in particular to a split-type all-terrain multi-rotor aircraft with anti-collision function. In particular, it involves split-type all-terrain multi-rotor aircraft with anti-collision function applied in dangerous fields such as field cave exploration, indoor inspection of burning buildings, chemical dangerous goods and radioactive material leakage. Background technique [0002] With the development of microcontrollers, MEMS, embedded and wireless communication technologies, and the popularization of open source flight controls such as APM, MWC, PPZ and MK, rotorcraft has become an important motion platform and carrier. Fields such as environmental monitoring, safety and security, and geological exploration are becoming more and more popular, and have become an important part of research fields such as intelligent control, and have also become an important outlet for scient...

AI Technical Summary

Problems solved by technology

However, the existing aircraft in the world generally adopt an integrated structure, the rotor is exposed outside the body, the system has more degrees of freedom, the pilot needs a long training time, and safety is difficult to guarantee, and accidents such as scratches may occur if there is a slight carelessness The communication distance of 2.4GHz frequency is limited, and it is difficult to apply in special occasions such as wild cave exploration, indoor inspection of burning buildings, etc.
