Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a load drive control signal strength indication system for a control system. Background Technology

[0002] Currently, the power unit control signal strength of popular drones on the market does not have an intuitive indication. In the following two situations, it is difficult to confirm whether the system status is normal: (1) If the power unit has no output after the control system is unlocked during teaching, debugging and maintenance, it is difficult to determine whether the problem is with the power unit itself or the control signal. (2) When the power unit can output normally, it is necessary to check whether the real-time output of the control signal matches the expected output after attitude deviation. At this time, it is necessary to use special instruments such as oscilloscopes to detect it. Otherwise, it is almost impossible to know whether the power unit drive signal has output, and whether the strength of the output is normal.

[0003] Meanwhile, in the existing teaching methods for UAV control principles, the explanation of attitude changes and power unit adjustment methods often relies on verbal descriptions or diagrams, making it difficult to intuitively demonstrate the correspondence between the flight control output signals and the actual working conditions of the power unit, which causes great confusion in teaching. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a load drive control signal strength indication system for a control system, thereby solving the problems mentioned in the background. This invention provides a direct indication of the motor control signal strength of a UAV. By collecting and processing the control signal, the control signal is graded into 10 intensity levels and then displayed by 10 LEDs, providing a direct indication of the real-time changes in the intensity of the motor control signal.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a control system load drive control signal strength indication system, comprising an indication module, which includes a control chip, an LED module, and a PWM control signal input terminal. The indication module is mounted on a drone, which includes a flight control system, a signal transmission line, a motor, and an ESC. The flight control system on the drone is electrically connected to the indication module via the signal transmission line. The indication system provides multiple signal input methods, and different control signals are introduced through a selection switch. The microcontroller collects the signals and classifies them, and the LED module is used for graded display.

[0006] Furthermore, the indicator module is also equipped with a positive power supply, a first power ground, a bus SCL, a bus SCK, and a second power ground.

[0007] Furthermore, the control chip is connected to the signal transmission line, and the control chip is used to analyze the transmitted signal and control the LED module.

[0008] Furthermore, the number of LED beads in the LED module is the same as the number of levels.

[0009] Furthermore, the indicator module outputs each LED module for hierarchical display via I / O ports.

[0010] Furthermore, the signal input methods include PWM control and serial data control.

[0011] Furthermore, the microcontroller analyzes the signal through its internal sampling program to obtain signal strength data.

[0012] Furthermore, the indicating system turns on the corresponding gating switch according to the determined control signal type and turns off the remaining gating switches.

[0013] The beneficial effects of this utility model are:

[0014] 1. The load drive control signal strength indication system of this control system realizes intuitive indication of the motor control signal strength of the UAV. After the control signal is collected and processed, the control signal is classified into 10 strength levels and then displayed by 10 LEDs, which intuitively indicates the real-time intensity change of the motor control signal.

[0015] 2. The load drive control signal strength indication system of this control system solves the problem of intuitive indication of the motor control signal strength during actual operation, providing intuitive real-time status indication for debugging and maintenance, thereby quickly and intuitively judging the health status of the motor control signal.

[0016] 3. The load drive control signal strength indication system of this control system solves the problem that the correspondence between the strength of the real-time motor control signal and the flight attitude adjustment cannot be known during the flight of traditional UAVs. At the same time, it can intuitively demonstrate the correspondence between flight attitude changes and control methods in UAV teaching. Attached Figure Description

[0023] The load drive control signal strength indication system of this control system realizes an intuitive indication of the control signal strength of the UAV motor 4. By collecting and processing the control signal, the control signal is classified into 10 strength levels and then displayed by 10 LEDs, which intuitively indicates the real-time intensity change of the motor 4 control signal.

[0024] In this embodiment, the indicator module 1 is also equipped with a positive power supply 8, a first power ground 9, a bus SCL10, a bus SCK11, and a second power ground 13. The control chip 6 is connected to the signal transmission line 3, and the control chip 6 is used to analyze the transmitted signals and control the LED module 7. The number of LED beads in the LED module 7 is the same as the number of levels.

[0025] In this embodiment, the indicator module 1 outputs the display of each LED module 7 through its I / O port for hierarchical display. The signal input methods include PWM control and serial data control. The microcontroller parses the signal through its internal sampling program to obtain signal strength data.

[0026] The aforementioned indicator system provides a clear indication of the strength of the motor 4 control signal during actual operation, offering intuitive real-time status indicators for debugging and maintenance, thus enabling quick and intuitive assessment of the health status of the motor 4 control signal.

[0027] Example 1

[0028] 1. In this embodiment, the microcontroller uses the ATmega328P chip manufactured by Microchip Technology.

[0029] 2. The input strobe switch adopts a 3-position switch.

[0030] 3. The set switch is connected to the P0.1, P0.2, and P0.3 ports of the microcontroller. The P0.1, P0.2, and P0.3 ports are programmed to be defined as PWM signal input, serial data input, and other control signal input, respectively.

[0031] 4. Connect 10 LEDs to the P1.0-P1.7, P2.0, and P2.1 ports of the microcontroller as output signal indicators.

[0032] 5. In this embodiment, the entire workflow is as follows: First, determine the type of control signal. For example, when the control signal is PWM, turn on the PWM gating switch and turn off the remaining gating switches. At this time, connect the PWM control signal to the P01 input port and use the sampling program inside the microcontroller to analyze the PWM signal to obtain the signal strength data.

[0033] The program then divides the intensity data into 10 intensity levels and outputs corresponding values ​​through ports P1.0-P1.7, P2.0, and P2.1. For example, when the drive intensity is detected as level 1, the microcontroller will light up the LED on port P1.0; when the drive intensity is level 2, the microcontroller will light up the LEDs on ports P1.0 and P1.1. This continues until the drive intensity reaches the maximum of level 10, at which point the microcontroller will light up all 10 LEDs on ports P1.0-P1.7, P2.0, and P2.1. When the PWM signal intensity changes rapidly, the microcontroller's output will also drive the 10 LEDs to change in real time, thus quickly reflecting the intensity changes of the PWM signal.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
