Four-axis aircraft balance stability control device based on cross-flow fan driving

Abstract

The invention relates to a four-axis aircraft balance stability control device based on cross-flow fan driving. The four-axis aircraft balance stability control device comprises a microprocessor module, a machine body attitude control module, a flight height detection module, a wireless transceiving module, a machine body bearing indication circuit, a serial port / serial wire debug (SWD) debugging interface circuit, a signal input / output and expansion interface and a power supply module. The wireless transceiving module, the machine body attitude control module and the flight height detection module are connected with the microprocessor module through a serial bus. The power supply module provides a working power supply for the microprocessor module, the machine body attitude control module, the flight height detection module, the wireless transceiving module, the serial port / SWD debugging interface circuit, the machine body bearing indication circuit and the signal input / output and expansion interface. The four-axis aircraft balance stability control device integrates functions of machine body attitude control, flight height detection and wireless transceiving and the like, and a machine body is reliable in stability and controllability in flying.

Description

technical field [0001] The invention belongs to the technical field of signal detection and relates to a balance and stability control device for a four-axis aircraft driven by a cross-flow fan. Background technique [0002] Four-blade, non-coaxial multi-rotor aircraft, referred to as quadcopter, is one of the typical aircraft that completely uses electronic control means to replace mechanical control means. The quadcopter is driven by a motor to drive the rotor. Its aerodynamic principle is very different from the traditional fixed-wing aircraft and the helicopter system based on pitch control in terms of power source and attitude control. The quadcopter completely abandons the complicated mechanical control parts of the traditional aircraft, and adopts the flight control system composed of micro-sensors and microprocessors, which simplifies the structure and weight of the aircraft to a considerable extent, and also reduces the manufacturing cost and assembly difficulty.

AI Technical Summary

Problems solved by technology

Most of them use low-cost and low-precision sensors, which are difficult to achieve the precision and reliability of professional inertial guidance units, so they cannot meet the actual requirements in terms of anti-external disturbance and controllability

At the same time, these products often do not have or only have a very simple navigation method, and can only use manual remote control to control the flight within the visual range of the naked eye, which is far from reaching the level of commercial and military value.
