Problems solved by technology

[0004] (1) In terms of structure: Most quadrotor aircraft on the market adopt an integrated structure. Although this design is convenient for mass production and aesthetically pleasing, it cannot meet the requirements of the majority of quadrotor professional users for the modular disassembly of the aircraft body. When a module on the circuit is damaged, it is often necessary to replace the entire control circuit or drive circuit, which is too expensive for the user to replace, and also causes unnecessary waste;
[0005] (2) In terms of control chips: most of the flight control chips on the market use foreign 16-bit and 32-bit single-chip microcomputers. The high cost also makes the domestic flight control chip market sluggish for a long time

Embodiment 1

[0028] The main structure of the modular control board for quadrotor aircraft involved in this embodiment includes a main control module 1, a wireless module 2, a gyroscope module 3, a power supply and a voltage stabilizing circuit 4, a motor and a driving module 5, and a power supply and a voltage stabilizing circuit 4 respectively electrically connected with the main control module 1, wireless module 2, gyroscope module 3 and motor and drive module 5 to provide power supply, and the main control module 1 is electrically connected with the wireless module 2, gyroscope module 3 and motor and drive module 5 respectively , for receiving and processing data information from the wireless module 2 and the gyroscope module 3, the wireless module 2 is responsible for transmitting control information, the gyroscope module 3 is used to detect the flight attitude, and the PWM generated by the motor and drive module 5 in the main control module 1 Provide power for the aircraft under signa...

Embodiment 2

[0035] This embodiment takes the modular control panel for a quadrotor aircraft described in Embodiment 1 as an example, and its specific workflow is:

[0036] (1) The power supply and the voltage stabilizing circuit 4 provide suitable power for the normal operation of each module of the control board. After the control board is powered on, each module is initialized and interrupted. If a calibration signal is received at this time, the gyroscope 3 is cleared. Otherwise, the main control module 1 receives the data from the gyroscope module 3 and performs Kalman filtering, uses the quaternion to calculate the inclination angle to obtain the current attitude of the quadrotor aircraft, and applies the flight control method of the quadrotor aircraft based on digital PID (that is, proportional-integral -differential control), by selecting the control gain to make the system realize the desired performance, the parameters of the quadrotor are adjusted by the host computer software to...

Embodiment 3

[0041] At present, the flight control board PC software of quadrotor aircraft is mainly designed for 16-bit AVR single-chip microcomputer and 32-bit STM32 single-chip microcomputer. The domestic chip IAP15W4K58S4 single-chip microcomputer is the main control module 1 and there is no flight control board PC software for quad-rotor aircraft. Therefore, in the present embodiment, the upper computer software for the main control module 1 domestic chip IAP15W4K58S4 single-chip microcomputer has been designed; the modular control panel of the quadrotor aircraft can be connected with the upper computer software through the USB interface, and realize adjustment or modification of the quadrotor aircraft PID Parameters and the function of displaying the flight attitude; the host computer software connected to the main control module 1 includes two parts of flight attitude display and flight attitude control:

Abstract

The invention belongs to the technical field of unmanned plane control, and relates to a modular type control panel for a four-rotor aircraft. A power supply and a voltage-stabilizing circuit are respectively in electrical connection with a main control module, a wireless module, a gyroscope module, and a motor and drive module, so as to supply power. The main control module is electrically connected with the wireless module, the gyroscope module, the motor and drive module, and is used for receiving and processing data information from the wireless module and the gyroscope module. The wireless module is used for transmitting control information, and the gyroscope module is used for detecting the flight attitude. The motor and drive module is controlled by a PWM signal generated by the main control module to supply power to an aircraft. The main control module and a gyroscope achieve data transmission and communication through an I2C protocol, and the main control module and the wireless module achieve data transmission and communication through an SPI protocol, so as to achieve the modular control of the four-rotor aircraft. The control panel is simple in overall structure, is convenient to install, and is easy to operate.

Description

Technical field: [0001] The invention belongs to the technical field of unmanned aerial vehicle control, and relates to a control board, in particular to a modular control board suitable for quadrotor aircraft, which adopts a modular structure design, has high versatility, is easy to maintain, and can adjust parameters in real time Features. Background technique: [0002] Quadrotor aircraft is a six-degree-of-freedom vertical take-off and landing aircraft that can accomplish tasks that fixed-wing aircraft cannot accomplish, such as hovering, low-speed flight, vertical take-off and landing, and indoor flight. For aircraft, the relative quadrotors have the same rotation direction. Compared with traditional helicopters, it has the advantages of simple structure and control, low manufacturing precision requirements, good stability, and weak gyro effect. , traffic management, forest fire prevention, urban patrol and other fields have broad application prospects, and become an in...
