[0050] Figure 1 A flowchart of a mechanical antenna control method provided by the embodiments of the present application is shown in FIG. 1. The method can be applied to a mechanical antenna control system, such as the mechanical antenna control system shown in FIG. 2. Figure 2 As shown in FIG. 2, the mechanical antenna control system includes:

[0051] A permanent magnet motor is used to start running according to preset initial rotation speed parameters, to drive the mechanical antenna to run.

[0052] A rotation speed control module is used to receive a rotation speed adjustment signal output by a potentiometer, and convert the rotation speed adjustment signal into a PWM signal, to adjust the rotation speed of the permanent magnet motor based on the PWM signal.

[0053] A rotation speed feedback module is used to measure the actual rotation speed of the permanent magnet motor, and convert the actual rotation speed into a rotation speed pulse signal, and convert the rotation speed pulse signal into an actual rotation speed value for display.

[0054] A feedback adjustment module is used to adjust the rotation speed parameters of the permanent magnet motor according to the actual rotation speed value and the expected rotation speed, so that the rotation speed of the motor reaches the expected rotation speed, to make the mechanical antenna reach the expected frequency.

[0055] In a possible implementation, the rotation speed control module can include:

[0056] A potentiometer is used to output an analog value for controlling the rotation speed of the permanent magnet motor.

[0057] A UNO board is used to receive the analog value, convert the analog value into a PWM signal, and output the PWM signal to an L298N motor drive chip.

[0058] The L298N motor drive chip is used to receive the PWM signal, and adjust the rotation speed of the permanent magnet motor based on the PWM signal.

[0059] Based on the mechanical antenna control system, a mechanical antenna control method can include the following steps, as shown in FIG. 1. Figure 1 As shown in FIG. 1, the mechanical antenna control method can include the following steps:

[0060] S101, control the permanent magnet motor to start running according to preset initial rotation speed parameters, to drive the mechanical antenna to run.

[0061] In embodiments of the present application, a user can preset an initial rotation speed parameter of a permanent magnet motor (hereinafter referred to as motor) so that the motor can run at the preset initial rotation speed. As an example, the initial rotation speed parameter can be a target rotation speed when the motor starts. This parameter can be set in advance according to the operation requirements of the mechanical antenna. For example, if the mechanical antenna needs to start rotating smoothly and slowly, the initial rotation speed parameter can be set to a low value, such as a few dozen revolutions per minute. The initial rotation speed parameter can be stored in a storage unit of a motor control system, and the control system will control the starting process of the motor according to this parameter. The starting of the permanent magnet motor can be realized through the motor control system. The motor control system can send a control signal to the driving circuit of the motor according to the preset initial rotation speed parameter, so that the motor starts rotating at the set initial rotation speed. The permanent magnet motor can be connected to the mechanical antenna. When the motor starts running according to the preset initial rotation speed parameter, the mechanical energy output by the motor can be transmitted to the mechanical antenna, so that the mechanical antenna starts running in a predetermined motion mode under the driving of the motor.

[0062] S102, receiving the rotation speed adjustment signal output by the potentiometer.

[0063] In embodiments of the present application, the potentiometer can be a variable resistor. By adjusting the potentiometer, the potentiometer can output a signal related to the rotation speed, i.e. a rotation speed adjustment signal, such as a voltage signal. This signal can represent the target rotation speed that the user hopes the motor to achieve. For example, when the potentiometer knob is adjusted to the middle position, the potentiometer outputs a medium voltage value, indicating that the motor is expected to run at a medium speed. In this way, the rotation speed adjustment signal output by the potentiometer can be received.

[0064] In a possible implementation, the initial rotation speed parameter can be set through the UNO board of the rotation speed control module.

[0065] In embodiments of the present application, the UNO board (such as Arduino UNO) is a microcontroller development board that can receive user input parameters and store and process them. In embodiments of the present application, the UNO board can be used to set the initial rotation speed parameter of the permanent magnet motor. As an example, the user can input the initial rotation speed parameter to the UNO board in some way (for example, through a potentiometer, a button, a serial communication or other input device connected to the UNO board). When the motor starts, the UNO board can read the stored initial rotation speed parameter and generate a corresponding PWM signal according to this parameter. This PWM signal is then sent to the motor driving chip (such as L298N) to control the motor to start running at the set initial rotation speed.

[0066] Storage parameter: After the UNO board receives the initial rotation speed value input by the user, it stores it in the internal storage unit. This stored value will be used as the reference rotation speed when the motor is started.

[0067] S103, convert the rotation speed adjustment signal into a PWM signal, and adjust the rotation speed of the permanent magnet motor based on the PWM signal.

[0068] In the embodiments of the present application, the PWM (Pulse Width Modulation) signal is a signal that adjusts the rotation speed of the motor by controlling the width of the pulse. The system (i.e. the control system of the mechanical antenna) can first convert the voltage signal output by the potentiometer into a PWM signal. Then, this PWM signal can be sent to the motor. The motor can adjust its rotation speed according to the pulse width of the PWM signal. It can be understood that the greater the pulse width, the higher the rotation speed of the motor; the smaller the pulse width, the lower the rotation speed of the motor.

[0069] S104, measure the actual rotation speed of the permanent magnet motor, and convert the actual rotation speed into a rotation speed pulse signal.

[0070] In the embodiments of the present application, the actual rotation speed of the permanent magnet motor can be measured by a rotation speed sensor. The rotation speed sensor can generate a pulse signal according to the rotation of the motor, and each pulse in the pulse signal can represent a certain angle of rotation of the motor. These pulse signals can reflect the actual rotation speed of the motor. It can be understood that the more pulses generated per second, the higher the rotation speed of the motor.

[0071] S105, convert the rotation speed pulse signal into an actual rotation speed value for display.

[0072] In the embodiments of the present application, the system can convert the pulse signal measured by the rotation speed sensor into a specific rotation speed value (such as revolutions per minute RPM), i.e. the actual rotation speed value of the motor. It can be understood that the actual rotation speed value of the motor can be displayed by a rotation speed display, so that the user can view the actual rotation speed of the motor in real time, and intuitively understand the actual running speed of the motor.

[0073] S106, adjust the rotation speed parameter of the permanent magnet motor according to the actual rotation speed value and the expected rotation speed, so that the rotation speed of the motor reaches the expected rotation speed, so that the mechanical antenna reaches the expected frequency.

[0074] In the embodiments of the present application, the system can compare the actual speed value of the motor with the expected speed set by the user, and adjust the speed parameter of the permanent magnet motor according to the actual speed value and the expected speed, so that the speed of the motor reaches the expected speed, so that the mechanical antenna reaches the expected frequency, wherein the expected speed can be set by a potentiometer, for example. For example, if the actual speed is lower than the expected speed, the pulse width of the PWM signal can be increased to increase the speed of the motor; on the contrary, if the actual speed is higher than the expected speed, the pulse width of the PWM signal can be reduced to reduce the speed of the motor. In this way, the speed parameter of the motor can be continuously adjusted until the actual speed of the motor is consistent with the expected speed, thereby ensuring that the mechanical antenna can operate at the expected frequency.

[0075] In the embodiments of the present application, the permanent magnet motor is controlled to start operating according to the preset initial speed parameter to drive the mechanical antenna to operate; a speed adjustment signal output by a potentiometer is received; the speed adjustment signal is converted into a PWM signal, and the speed of the permanent magnet motor is adjusted based on the PWM signal; the actual speed of the permanent magnet motor is measured, and the actual speed is converted into a speed pulse signal; the speed pulse signal is converted into an actual speed value for display; and the speed parameter of the permanent magnet motor is adjusted according to the actual speed value and the expected speed, so that the speed of the motor reaches the expected speed, so that the mechanical antenna reaches the expected frequency. In this way, through accurate speed control, real-time feedback adjustment and user-friendly operation interface, the performance and operating stability of the mechanical antenna can be significantly improved.

[0076] In some possible implementations, receiving a speed adjustment signal output by a potentiometer includes:

[0077] The potentiometer of the speed adjustment control module outputs an analog value for controlling the speed of the permanent magnet motor.

[0078] In the embodiments of the present application, when the knob of the potentiometer is adjusted, the potentiometer outputs an analog voltage value related to the position of the knob, that is, an analog value, which represents the speed target that the user hopes the motor to reach. For example, if the knob is adjusted to the lowest position, the potentiometer outputs a lower voltage value, indicating that the motor is expected to operate at a lower speed; if the knob is adjusted to the middle position, the potentiometer outputs a medium voltage value, indicating that the motor is expected to operate at a medium speed; if the knob is adjusted to the highest position, the potentiometer outputs a higher voltage value, indicating that the motor is expected to operate at a higher speed. The analog value can be sent to the motor control system, which can adjust the speed of the motor according to the analog value. It can be understood that the higher the analog value, the higher the speed target of the motor; the lower the analog value, the lower the speed target of the motor.

[0079] In some possible implementations, the rotating speed adjusting signal is converted into a PWM signal, and the rotating speed of the permanent magnet motor is adjusted based on the PWM signal, including:

[0080] The analog value is received by the UNO board of the rotating speed control module;

[0081] The analog value is converted into a PWM signal;

[0082] The PWM signal is output to the L298N motor drive chip of the rotating speed control module;

[0083] The rotating speed of the permanent magnet motor is adjusted based on the PWM signal by the L298N motor drive chip.

[0084] In the embodiments of the present application, the analog value can be received by the UNO board of the rotating speed control module, for example, the analog value output by the potentiometer can be connected to the analog input pin of the UNO board, so that the UNO board can read this analog value. The UNO board can convert the received analog value into a corresponding PWM signal. As an example, the UNO board can generate a PWM pulse with a corresponding width according to the size of the analog value voltage. For example, a higher analog voltage value will generate a wider PWM pulse, and a lower analog voltage value will generate a narrower PWM pulse. The PWM signal generated by the UNO board can be sent to the input end of the L298N motor drive chip through the digital output pin, and the L298N chip can control the rotating speed of the motor according to the received PWM signal, for example, the permanent magnet motor can adjust its rotating speed according to the current and voltage provided by the L298N chip, and finally reach the rotating speed corresponding to the PWM signal.

[0085] In some possible implementations, the actual rotating speed of the permanent magnet motor is measured, and the actual rotating speed is converted into a rotating speed pulse signal, including:

[0086] The actual rotating speed of the permanent magnet motor is measured by using the rotating speed sensor of the rotating speed feedback module; wherein the rotating speed sensor is an optical rotating speed sensor;

[0087] The rotating speed signal of the actual rotating speed is converted into a rotating speed pulse signal.

[0088] In embodiments of the present application, the actual speed of the permanent magnet motor is measured, and the actual speed is converted into a speed pulse signal. The actual speed of the permanent magnet motor can be measured by an optical speed sensor, for example. The optical speed sensor can be installed near the motor shaft so that it can detect a mark on the motor shaft. When the motor is running, the optical speed sensor can detect the passing of the mark and generate an electrical signal, such as a pulse signal, related to the speed of the motor. It can be understood that the electrical signal output by the optical speed sensor is usually a pulse signal, and each pulse represents a certain angle of rotation of the motor shaft. For example, if there is a mark on the motor shaft, one pulse will be generated per revolution; if there are multiple marks, multiple pulses will be generated per revolution. The frequency of these pulse signals is directly proportional to the actual speed of the motor. By calculating the number of pulses generated per unit time, the actual speed of the motor can be determined. For example, if 100 pulses are generated per second and each pulse represents one revolution of the motor shaft, the actual speed of the motor is 100 revolutions per minute (RPM).

[0089] In some possible implementations, converting the speed pulse signal into an actual speed value for display includes:

[0090] converting the speed pulse signal into an actual speed value by a speed display of the speed feedback module;

[0091] displaying the actual speed value by the speed display.

[0092] In embodiments of the present application, the actual speed value can be displayed by the speed display. For example, the speed display can receive the pulse signal from the optical speed sensor and calculate the number of pulses received per unit time. For example, if 100 pulses are received per second and each pulse represents one revolution of the motor shaft, the actual speed of the motor is 100 revolutions per minute. In this way, the speed display can convert the speed pulse signal into an actual speed value. Then, the speed display can display the calculated actual speed value in real time. It can be understood that the value on the display screen can also be updated in real time to reflect the actual speed of the motor. For example, if the speed of the motor changes, the display will quickly update the displayed actual speed value. In this way, the user can monitor the running speed of the motor in real time to ensure that it meets the expected requirements.

[0093] In further possible implementations, adjusting the speed parameter of the permanent magnet motor according to the actual speed value and the expected speed so that the speed of the motor reaches the expected speed to make the mechanical antenna reach the expected frequency includes:

[0094] adjusting the speed parameter of the permanent magnet motor by the UNO board according to the actual speed value and the expected speed so that the speed of the permanent magnet motor reaches the expected speed to make the mechanical antenna reach the expected frequency.

[0095] In the embodiments of the present application, according to the actual speed value and the expected speed, the speed parameter of the permanent magnet motor is adjusted so that the speed of the motor reaches the expected speed, so that the mechanical antenna reaches the expected frequency. At this time, the actual speed and the expected speed can be compared first, for example, the UNO board can read the actual speed value and the expected speed value in real time, and compare the two. If the actual speed is inconsistent with the expected speed, the UNO board can take corresponding adjustment measures according to the difference. As an example, the UNO board can adjust the pulse width of the output PWM signal according to the difference between the actual speed and the expected speed. If the actual speed is lower than the expected speed, the UNO board can increase the pulse width of the PWM signal to increase the speed of the motor; if the actual speed is higher than the expected speed, the UNO board can reduce the pulse width of the PWM signal to reduce the speed of the motor. The adjusted PWM signal can be sent to the L298N motor drive chip through the digital output pin of the UNO board. After receiving the PWM signal output by the UNO board, the L298N motor drive chip can adjust the current and voltage of the motor according to the pulse width of the PWM signal, so as to control the speed of the motor to reach the expected speed. It can be understood that the speed of the permanent magnet motor can directly affect the operating frequency of the mechanical antenna, when the speed of the motor reaches the expected speed, the operating frequency of the mechanical antenna will also correspondingly reach the expected frequency, so as to ensure that the antenna can work normally according to the preset parameters.
