Abstract

The invention relates to an aerial photographing type rotor craft control system. According to the technical scheme, an ARM system module (2) is connected with a wireless transmission module (1), a gyro module (3), a barometer module (4), a GPS positioning module (5), an LED module (6) and a motor module (7); the ARM system module (2) is internally provided with control software of the craft control system. The control software and hardware of the craft control system act together, and the aerial photographing type rotor craft control system has the advantages of being good in anti-interference performance, high in bearing ratio, good in stability and high in gyroscopic effect resistance. The aerial photographing type rotor craft control system is suitable for being used for high altitude shooting and low altitude shooting equipment in various industries.

Description

technical field [0001] The invention belongs to the technical field of aircraft control systems. In particular, it relates to an aerial photographing type rotorcraft control system. Background technique [0002] The existing aerial photography rotorcraft technology is relatively mature, and can complete fixed-point hovering, low-speed and low-altitude flight, vertical take-off and landing, and indoor flight, and these actions cannot be completed by some fixed-wing aircraft. Although the aerial photography rotorcraft can be applied to on-the-spot shooting in multiple occasions, such as forests, crops and areas where poisonous and harmful obstacles are inaccessible to personnel. But its disadvantages are: it will show strong nonlinear characteristics in the case of high dynamic flight; it will be affected by the interference of airflow and various parameter perturbations during the flight; the load capacity is limited, and it is impossible to carry high-precision navigation e...
