Automatic navigation flight control system based on cross-flow fan

Abstract

The invention relates to an automatic navigation flight control system based on a cross-flow fan. The system comprises a power supply module, a microprocessor module, a body posture control module, a flight height detecting module, a digital compass module, a wireless data receiving and dispatching module, a GPS (Global Positioning System) positioning and navigating module, a serial port / SWD (Supersonic Wave Drive) debugging interface circuit and a signal input / output interface, wherein the body posture control module, the flight height detecting module, the digital compass module, the GPS positioning and navigating module and the wireless data receiving and dispatching module are connected with the microprocessor module through serial buses; and the power supply module provides a working power supply to the microprocessor module, the body posture control module, the flight height detecting module, the wireless data receiving and dispatching module, the serial port / SWD debugging interface circuit and a body state indication circuit. The system integrates the functions of body posture control, flight height detection, wireless receiving and dispatching and the like; and the body flight has reliable stability and controllability.

Description

technical field [0001] The invention belongs to the technical field of signal detection, and relates to an automatic navigation control system for a four-axis aircraft used for a cross-flow fan. Background technique [0002] Cross-flow fan, also known as cross-flow fan, is a special type of fan. The impeller is multi-leaf, long cylindrical, with forward multi-wing blades. It has simple structure, small size, stable air flow, and high dynamic pressure coefficient. Features, recently widely used in low-pressure ventilation occasions such as household appliances and air-conditioning equipment. Compared with the rotor as the driving method, the cross-flow fan has many advantages: since the axial length is not limited, the length of the impeller can be arbitrarily selected according to different use needs, and the power can be adjusted; the air flow flows through the impeller and is affected by the two forces of the blades , so it can reach a longer distance; there is no turbule...

AI Technical Summary

Problems solved by technology

Although there are some relatively complete and mature aircraft control boards on the market, most of them are multi-rotor quadcopters for aviation model enthusiasts. Most of them use low-cost and low-precision sensors, which are difficult to achieve the professional inertial guidance unit. Accuracy and reliability, so it cannot meet the actual requirements in terms of anti-external force disturbance, controllability, etc.

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. The potential commercial value and practical value are far from being developed.
