[0022] Currently, magnetic levitation toys generally use traditional analog circuit designs, such as using potentiometer components for magnetic levitation control.
[0023] However, in practical applications, it has been found that traditional magnetic levitation control methods, because their core parameters and configurations are fixed in the circuit design stage and are controlled by hardware components such as potentiometers, suffer from problems such as system response lag and decreased control accuracy when the levitation conditions of the magnetic levitation product change.
[0024] In view of this, this application provides a magnetic levitation control method and related equipment. By acquiring the voltage signal of the Hall sensor in real time, the spatial position of the magnetic float is accurately identified, and the magnetic field polarity of the electromagnet coil in the control circuit is adjusted in real time by generating control signals, thereby dynamically driving and controlling the magnetic float in the magnetic levitation control system, effectively improving the system response speed and accuracy.
[0025] The specific implementation methods of the embodiments of this application will be described in detail below with reference to the accompanying drawings. First, a magnetic levitation control method provided in the embodiments of this application will be described with reference to the accompanying drawings.
[0026] like Figure 1 As shown, Figure 1 This is a flowchart illustrating a magnetic levitation control method provided in an embodiment of this application, specifically including but not limited to steps 100 to 300.
[0027] Step 100: Acquire the voltage signal collected by the Hall sensor in real time; the voltage signal is generated based on the spatial position of the magnetic float in the magnetic levitation control system.
[0028] In this embodiment, the execution entity can be a microcontroller unit (MCU) chip installed in the magnetic levitation control system. The MCU chip acquires the voltage signal collected by the Hall sensor in real time. The Hall sensor, installed in the magnetic levitation control system, can measure the magnetic field strength or magnetic field change in real time, thereby generating a corresponding voltage signal based on the spatial position of the magnetic float. The magnetic float can be a suspended neodymium iron boron magnet.
[0029] In practical applications, the real-time acquisition of the voltage signal collected by the Hall sensor includes: Real-time acquisition of voltage signals collected by the first Hall sensor, the second Hall sensor, and the third Hall sensor; The first Hall sensor and the second Hall sensor are used to detect the spatial position of the magnetic float in the horizontal direction in the magnetic levitation control system and generate a corresponding voltage signal; the third Hall sensor is used to detect the spatial position of the magnetic float in the vertical direction in the magnetic levitation control system and generate a corresponding voltage signal.
[0030] In this embodiment, three Hall sensors can be installed in the magnetic levitation control system, specifically a first Hall sensor, a second Hall sensor, and a third Hall sensor. The first and second Hall sensors detect the spatial position of the magnetic float in the horizontal direction and generate corresponding voltage signals, i.e., they detect the spatial position on the two orthogonal axes X and Y in the horizontal direction. The third Hall sensor detects the spatial position of the magnetic float in the vertical direction and generates corresponding voltage signals, i.e., it detects the spatial position on the vertical Z-axis.
[0031] Therefore, the spatial position of the magnetic float in the magnetic levitation control system is sensed in real time by the first Hall sensor, the second Hall sensor and the third Hall sensor, and the corresponding voltage signal is generated according to the magnetic field strength or magnetic field change. The MCU chip is responsible for reading and identifying the signal so as to facilitate subsequent control and adjustment.
[0032] Step 200: Based on the voltage signal, determine the spatial position data information of the magnetic float.
[0033] In this embodiment, the MCU chip can determine the spatial position data of the magnetic float corresponding to each Hall sensor based on the voltage signals collected in real time by each Hall sensor and a preset matching rule.
[0034] For example, determining the spatial position data information of the magnetic float based on the voltage signal includes: Based on the voltage signals collected by the first Hall sensor and the second Hall sensor, the spatial position of the magnetic float in the magnetic levitation control system is mapped to the X-axis and Y-axis on the three-axis coordinate system to obtain the X-axis coordinate and Y-axis coordinate of the magnetic float. Based on the voltage signal collected by the third Hall sensor, the spatial position of the magnetic float in the magnetic levitation control system is mapped to the Z-axis on the three-axis coordinate system to obtain the Z-axis coordinate of the magnetic float. The three-axis coordinate system is constructed with the pre-set target stopping position of the magnetic float in the magnetic levitation control system as the origin.
[0035] In this embodiment, a three-axis coordinate system is constructed with the pre-set target stopping position of the magnetic float in the magnetic levitation control system as the central origin. Two orthogonal axes are provided in the horizontal direction, namely the X-axis and the Y-axis. The X-axis and the Y-axis correspond to two pairs of electromagnet coils, that is, two coils on each axis are diagonally distributed. The two coils on the same axis are connected in series. For example, there are coils A and B on the horizontal X-axis. Current flows in from the outer coil of coil A and flows out from the inner coil of coil A, and flows in from the inner coil of coil B and flows out from the outer coil of coil B. Furthermore, a Z-axis is provided in the vertical direction.
[0036] Furthermore, the spatial position of the magnetic float in the horizontal and vertical directions is sensed by the first Hall sensor, the second Hall sensor, and the third Hall sensor, and a voltage signal is generated by distance detection. The specific position of the magnetic float is determined by the magnitude of the voltage signal.
[0037] Furthermore, the MCU chip reads the voltage signals collected by the first Hall sensor, the second Hall sensor, and the third Hall sensor. Based on the preset voltage reference value of the magnetic float at the preset target stopping position, and according to the amplitude difference between the voltage data, it can map the spatial position of the magnetic float in the magnetic levitation control system to the X and Y axes on the three-axis coordinate system to obtain the X-axis and Y-axis coordinates of the magnetic float. It also maps the spatial position of the magnetic float in the magnetic levitation control system to the Z-axis on the three-axis coordinate system to obtain the Z-axis coordinate of the magnetic float. Then, by combining the three-axis coordinates, it can accurately identify and locate the spatial position data information of the magnetic float.
[0038] For example, taking Z-axis detection as an example, when the magnetic float is not in the magnetic levitation control system, the voltage data of the voltage signal detected by the third Hall sensor on the Z-axis is constant within a fixed range. When the user places the magnetic float close to the magnetic levitation base of the magnetic levitation control system, the Hall sensor on the Z-axis will output a voltage signal that varies proportionally according to the polarity, orientation and distance of the magnet. For example, it can be set to increase the voltage signal amplitude when the N pole of the magnetic float is close to the front of the third Hall sensor and decrease the voltage when it is close to the back of the third Hall sensor.
[0039] Therefore, by using a preset matching rule, the voltage signals collected by the first Hall sensor, the second Hall sensor, and the third Hall sensor can be mapped to the specific coordinates of the magnetic float on the X, Y, and Z axes in the three-axis coordinate system, thereby constructing the spatial position data information of the magnetic float.
[0040] In practical applications, the method further includes: Determine the voltage data of the voltage signal acquired by the third Hall sensor; When the voltage data matches a preset threshold, the first Hall sensor, the second Hall sensor, and the control circuit are kept in a sleep state. If the voltage data does not match the preset threshold, the control circuit is activated to start acquiring the voltage signals of the first Hall sensor and the second Hall sensor in real time.
[0041] In this embodiment of the application, the voltage signal collected by the third Hall sensor in real time can be used as the trigger signal for the working state of the magnetic levitation control system.
[0042] Specifically, when the magnetic float does not enter the magnetic levitation control system, the voltage data of the voltage signal detected by the third Hall sensor on the Z-axis is constant within a fixed range. The preset threshold can be set to this fixed value. If the voltage data of the voltage signal collected by the third Hall sensor matches the preset threshold, it can be determined that the magnetic float has not entered the magnetic levitation control system at this time. Therefore, the first Hall sensor, the second Hall sensor and the control circuit can be kept in a dormant state, reducing the power consumption of the overall system.
[0043] Furthermore, when a mismatch is detected between the voltage data and the preset threshold, it indicates that the magnetic float has entered the magnetic levitation control system, the control circuit is activated, the voltage signals fed back from the XY axis are received and processed, and control signals are output.
[0044] For example, when the magnetic float is not in the magnetic levitation control system, the voltage signal detected by the third Hall sensor on the Z-axis is a reference voltage of 2.5V. When a magnetic float is detected above the base, a voltage signal that varies proportionally according to the polarity, orientation and distance of the magnet is output, that is, higher or lower than the reference voltage of 2.5V.
[0045] In practical applications, the levitation height of the magnetic float can be determined by detecting the voltage change of the voltage signal collected by the third Hall sensor. Then, the MCU chip analyzes the load-bearing state, automatically adjusts the power output of the electromagnet coil, and adjusts the levitation height of the magnetic float by controlling the duty cycle of the PWM signal of the MOS transistor switch.
[0046] Step 300: Based on the spatial position data of the magnetic float, a control signal is generated and output to the control circuit in the magnetic levitation control system to drive and control the levitation state of the magnetic float in the magnetic levitation control system; wherein, the control signal is used to adjust the current direction in the control circuit, thereby controlling the magnetic field polarity of the electromagnet coil connected to the control circuit.
[0047] In this embodiment, the MCU chip generates a control signal based on the spatial position data of the magnetic float and outputs it to the control circuit in the magnetic levitation control system. By controlling the current direction of the control circuit, the polarity of the magnetic field of the electromagnet coil connected to the control circuit can change in real time according to the spatial position data of the magnetic float. The levitation state of the magnetic float in the magnetic levitation control system can be driven and controlled by the magnetic effect of like poles repelling and unlike poles attracting.
[0048] Therefore, this application uses an MCU chip as the execution subject to collect the voltage signal of the Hall sensor in real time, accurately identify the spatial position of the magnetic float, and adjust the magnetic field polarity of the electromagnet coil in the control circuit in real time by generating control signals, thereby dynamically driving and controlling the magnetic float in the magnetic levitation control system, effectively improving the system response speed and accuracy, and quickly adjusting the levitation position of the magnetic float.
[0049] Specifically, as an optional implementation, the step of generating a control signal based on the spatial position data of the magnetic levitation buoy and outputting it to the control circuit in the magnetic levitation control system to drive and control the levitation state of the magnetic levitation buoy in the magnetic levitation control system includes: Based on the X-axis and Y-axis coordinates of the magnetic float, determine the quadrant information of the magnetic float; Based on the preset control strategy mapping rules and combined with the quadrant information of the magnetic float, a control signal matching the quadrant information is generated; The control signal is output to the control circuit in the magnetic levitation control system. By adjusting the on / off state of the switching transistor in the control circuit, the direction of the current in the control circuit is adjusted, the polarity of the magnetic field of the electromagnet coil connected to the control circuit is controlled, and the levitation state of the magnetic float in the magnetic levitation control system is driven and controlled.
[0050] In this embodiment of the application, the spatial position of the magnetic float can be mapped to the X-axis and Y-axis of the constructed three-axis coordinate system based on the voltage signals of the first Hall sensor and the second Hall sensor. Thus, based on the X-axis coordinates and Y-axis coordinates of the magnetic float, the corresponding quadrant information can be determined. For example, the spatial position of the magnetic float is the positive half-axis of the X-axis and the positive half-axis of the Y-axis, thereby determining that the magnetic float is in the first quadrant.
[0051] Furthermore, based on the preset control strategy mapping rules and combined with the quadrant information of the magnetic float, a control signal matching the quadrant information is generated. Since two electromagnet coils are diagonally distributed on the X-axis and two diagonally distributed on the Y-axis, and these two sets of electromagnet coils are connected in series, the two electromagnet coils on the X-axis exhibit opposite magnetic polarities under the same current direction, corresponding to the positive and negative X-axis semi-axes respectively; similarly, the two electromagnet coils on the Y-axis also exhibit opposite magnetic polarities under the same current direction, corresponding to the positive and negative Y-axis semi-axes respectively.
[0052] Therefore, based on the quadrant information of the magnetic float, the current direction of the electromagnet coil in different quadrants can be preset. For example, when the magnetic float is located in the first quadrant, the electromagnet coil on the positive half-axis of the X-axis can be set to generate a magnetic field of the same polarity as the magnetic float, providing a repulsive force, and the electromagnet coil on the negative half-axis of the X-axis can be set to generate a magnetic field of opposite polarity to the magnetic float, providing an attractive force, thereby forming a restoring torque on the X-axis. Furthermore, the electromagnet coil on the positive half-axis of the Y-axis can also be set to generate a magnetic field of the same polarity as the magnetic float, providing a repulsive force, and the electromagnet coil on the negative half-axis of the Y-axis can be set to generate a magnetic field of opposite polarity to the magnetic float, providing an attractive force, thereby forming a restoring torque on the Y-axis.
[0053] Therefore, once the quadrant information of the magnetic float is determined, a control signal matching the quadrant information can be quickly generated according to the preset control strategy mapping rules. The control signal is then output to the control circuit in the magnetic levitation control system. By adjusting the on / off state of the switching transistors in the control circuit, the direction of the current in the circuit is adjusted, ultimately controlling the magnetic field polarity of the electromagnet coil connected to the control circuit and driving the levitation state of the magnetic float in the magnetic levitation control system.
[0054] For example, please refer to Figure 2 , Figure 2 This is a schematic diagram of a control circuit provided in an embodiment of this application, in which two electromagnet coils on the same axis are connected in series to the control circuit. The control circuit can be an H-bridge circuit or a full-bridge circuit.
[0055] Therefore, by supplying power to the control circuit through the positive and ground terminals of the power supply, and controlling the on / off state of the four switching transistors through the control signals of the MCU chip, the direction of the current in the electromagnet coil can be controlled.
[0056] In practical applications, the two electromagnet coils on the X-axis can be connected to the first control circuit, and the two electromagnet coils on the Y-axis can be connected to the second control circuit, thereby achieving independent control of the X-axis and Y-axis without interference.
[0057] Furthermore, when a set of diagonal switches is turned on, for example, when switches 1 and 4 are turned on, the current will flow from the positive terminal of the power supply through switch 1, the electromagnet coil, and switch 4 to the power supply ground, thereby switching one side of the electromagnet coil as the S pole and the other side as the N pole. When another set of diagonal switches is turned on, for example, when switches 2 and 3 are turned on, the current will flow from the positive terminal of the power supply through switch 2, the electromagnet coil, and switch 3 to the power supply ground, thereby switching one side of the electromagnet coil as the N pole and the other side as the S pole.
[0058] It is understandable that when the control circuit is in operation, only one set of diagonal switches is turned on, while the other set of switches will be turned off.
[0059] Therefore, by identifying the spatial position data of the magnetic float through the MCU chip and outputting the corresponding control signal to the control circuit according to the preset control strategy mapping rules, the forward and reverse flow of current can be realized, and finally the polarity switching control of the magnetic field of the electromagnet coil can be realized. This allows for rapid adjustment of the levitation state of the magnetic float in the magnetic levitation control system. Compared with the existing adjustment methods using hardware components such as potentiometers, this method can effectively improve the response speed and accuracy of the magnetic levitation system.
