Four-rotor aircraft control system based on dual-tone multi-frequency signal and method

Abstract

The invention provides a four-rotor aircraft control system based on a dual-tone multi-frequency signal and a method. The four-rotor aircraft control system comprises a dual-tone multi-frequency signal receiving module 1, a dual-tone multi-frequency signal decoding module 5, a main control module 6, a flying control module 11, a power supply module 12 and a user control terminal 18. A number corresponding to a subscriber identity module (SIM) card which is installed on the dual-tone multi-frequency signal receiving module 1 is dialed by a controller. A corresponding key is selected and touched by the controller according to the requirement after the connection, a dual-tone multi-frequency signal corresponding to the key is transmitted to the dual-tone multi-frequency signal receiving module 1, and finally the signal is transmitted to the dual-tone multi-frequency signal decoding module 5 to be decoded. A corresponding binary code is generated through the decoding, the main control module 6 reads the binary code to be solved so as to generate a corresponding pulse position modulation signal, the flying control module 11 obtains the voltage control quantity of a motor through the calculation according to the pulse position modulation signal so as to control the flying posture. Due to the adoption of the control system and the method, a telephone of any model can be connected with a four-rotor aircraft, so that the adaptability is strong, and the control distance is remarkably enlarged.

Description

technical field [0001] The invention relates to a control system and method for a quadrotor aircraft, in particular to a control system and method for a quadrotor aircraft based on dual-tone multi-frequency signals, and belongs to the technical fields of communication, signal processing and automatic control. Background technique [0002] With the rapid development of science and technology and the continuous improvement of people's living standards, remote-controlled aerial vehicles have greatly facilitated and enriched people's daily production and life, and are increasingly favored by people. Among them, the quadrotor aircraft is an aircraft with four propellers, and the four propellers are in a cross-shaped cross structure. The opposite quadrotors have the same rotation direction and are divided into two groups, and the rotation directions of the two groups are different (the four propellers can be Divided into two groups according to the direction of rotation, one posit...
