Description

Technical Field

[0001] The present invention relates to the technical field of eddy current drive control, and in particular to a controllable drive control system and equipment for an eddy current drive switch. Background Art

[0002] When a thyristor is used as an electronic switch, the core function of its drive circuit is to push the thyristor from the blocking state to the conducting state by applying a trigger signal that meets the specifications, thereby achieving precise control of the on and off of the main circuit. This circuit needs to accurately adjust the phase, frequency or timing of the trigger pulse according to the type of thyristor and the specific application scenario. It must ensure the stability and reliability of the triggering action, and integrate the necessary isolation protection mechanism to block the interference of high voltage and large current in the main circuit on the control loop. It is the core support for ensuring the safety of thyristors and the efficient execution of switching actions.

[0003] For example, the electronic eddy current retarder drive controller and its control method provided by Chinese patent publication number: CN107344501B include an MCU processor unit and a switch gear signal input shaping unit, a frequency vehicle speed signal input shaping unit, a CAN communication unit, an AD conversion unit, a switch indicator light signal output control unit, a switch brake light signal output control unit, and a switch power drive load output control unit electrically connected thereto; the switch power drive load output control unit is also electrically connected to an analog current signal acquisition unit, a load freewheeling unit and an overvoltage protection unit, and the input end of the AD module acquisition unit is electrically connected to an analog temperature signal acquisition unit and an analog current signal acquisition unit.

[0004] However, the above scheme does not take into account that when using thyristors as electronic switches, a higher capacitor voltage and an adapted inductance are usually selected, and the discharge speed is affected by the capacitor voltage and the inductance of the drive coil. There is a lack of effective active control means, which leads to uncontrollable rapid discharge during the discharge process, causing the switch movable mechanism to instantly generate excessive acceleration, making it difficult to achieve smooth deceleration. In turn, the limit structure at the target position is impacted by inertia, causing rebound, resulting in poor contact when the switch is turned on and off. Summary of the Invention

[0005] Technical problems solved In response to the shortcomings of the existing technology, the present invention provides a controllable drive control system and equipment for eddy current driven switches, which solves the problem that under thyristor drive, uncontrollable discharge causes excessive acceleration of the mechanism and impact rebound, resulting in poor contact when the switch is turned on and off.

[0006] Technical Solution To achieve the above objectives, the present invention is implemented through the following technical solutions: a controllable drive control system and equipment for eddy current driven switches, including the following specific modules and equipment: a central computing and processing module: obtaining driving parameters based on experiments, the driving parameters including the distance from the initial position to the target position of the switch movable mechanism, the friction coefficient on the slide rail, the maximum acceleration driving current, the mass of the switch movable mechanism, the magnetic field strength of the space where the switch movable mechanism is located, and the effective length of the switch movable mechanism in the magnetic field; performing motion, force and current analysis on the switch movable mechanism based on the driving parameters, and performing standardized processing while comprehensively calculating to obtain the reduced pressure of the switch movable mechanism. The acceleration moment is recorded as the deceleration moment to determine the time node for controlling the current delivery and to judge whether the moment of driving the switch movable mechanism reaches the deceleration moment; the sinusoidal pulse width modulation signal module: based on the instruction of the central computing and processing module, when the deceleration moment has not been reached, it sends a signal to open the conductive channel, and when the deceleration moment has been reached, it sends a signal to close the conductive channel; the insulated gate bipolar transistor execution switch module: receives and executes the signal to open the conductive channel, so that the DC power supply delivers the maximum acceleration drive current to the eddy current coil, or receives and executes the signal to close the conductive channel, stops the DC power supply from delivering the maximum acceleration drive current to the eddy current coil, and ends the control.

[0007] Furthermore, the specific method of obtaining the deceleration moment is as follows: according to the maximum acceleration drive current, the magnetic field strength of the space where the switch movable mechanism is located, and the effective length of the switch movable mechanism in the magnetic field, the electromagnetic force is calculated in combination with the Ampere force formula; according to the friction coefficient on the slide rail and the mass of the switch movable mechanism, the obstruction friction force is calculated in combination with the friction force formula; when the switch movable mechanism overcomes the obstruction friction force under the action of the electromagnetic force, the positive driving force is obtained, and in combination with Newton's second law formula, the positive acceleration of the switch movable mechanism is obtained; the time when the switch movable mechanism moves to this midway position is set as the acceleration time; according to the positive acceleration and the acceleration time, the acceleration displacement of the switch movable mechanism is calculated in combination with the uniformly accelerated linear motion displacement formula; in addition, the acceleration is calculated in combination with the uniformly accelerated linear motion velocity formula. Speed. After this moment, the switch movable mechanism decelerates. During the deceleration process, the electromagnetic force disappears, overcoming the obstructing friction force and obtaining the counter-driving force. Combined with Newton's second law, the reverse acceleration of the switch movable mechanism is obtained. The time it takes for the switch movable mechanism to move from this midway position to the target position is set as the deceleration time. According to the reverse acceleration and deceleration time, combined with the uniformly accelerated linear motion displacement formula, the deceleration displacement of the switch movable mechanism is calculated. In addition, combined with the uniformly accelerated linear motion speed formula, the deceleration speed is calculated. At the moment of this midway position, the acceleration speed is equal to the deceleration speed. The sum of the acceleration displacement of the switch movable mechanism and the deceleration displacement of the switch movable mechanism is equal to the distance from the initial position to the target position of the switch movable mechanism. Therefore, a set of equations is established to calculate the moment at this midway position and record it as the deceleration time. ;in, Indicates the acceleration speed, Indicates the deceleration speed, Indicates the accelerated displacement of the switch mechanism, Indicates the deceleration displacement of the switch movable mechanism, Indicates the distance from the initial position to the target position of the switch movable mechanism.

[0008] Furthermore, the electromagnetic force is specifically obtained as follows: setting and calibrating the material coefficient of the switch movable mechanism and establishing an attenuation function; performing calculations based on the maximum acceleration drive current, the material coefficient of the switch movable mechanism, and the attenuation function to obtain the eddy current induced in the switch movable mechanism; and performing calculations based on the magnetic field strength of the space in which the switch movable mechanism is located, the eddy current induced in the switch movable mechanism, and the effective length of the switch movable mechanism in the magnetic field to obtain the electromagnetic force; ;in, represents the electromagnetic force, Indicates the magnetic field strength in the space where the switch mechanism is located, represents the eddy current induced in the switch mechanism, Indicates the effective length of the switch mechanism in the magnetic field.

[0009] Furthermore, the specific method of obtaining the hindering friction force is as follows: according to the known gravitational acceleration and the mass of the switch movable mechanism, the product is calculated to obtain the pressure of the switch movable mechanism on the slide rail, and according to the pressure of the switch movable mechanism on the slide rail and the friction coefficient on the slide rail, the hindering friction force is obtained.

[0014] Furthermore, the specific method of judging whether the moment of driving the switch movable mechanism has reached the deceleration moment is: recording the moment of system startup as the actual start moment, recording the current moment as the actual current moment, calculating the difference between the actual current moment and the actual start moment to obtain the actual time period, calculating the difference between the deceleration moment and the actual start moment to obtain the preset time period, comparing the actual time period with the preset time period, if the actual time period is less than the preset time period, it means that the deceleration moment has not been reached, if the actual time period is equal to the preset time period, it means that the deceleration moment has been reached.

[0015] The present invention also provides an electronic device that runs a controllable drive control system for an eddy current driven switch.

[0016] Beneficial effects Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects: 1. The central processing module integrates multiple parameters of the switch mechanism, including distance, friction coefficient, current, mass, and magnetic field strength, to accurately calculate the deceleration moment based on the Ampere force formula, Newton's second law, and the uniformly accelerated motion formula. The sinusoidal pulse width modulation signal module collaborates with the insulated gate bipolar transistor execution module to promptly cut off the current at the deceleration moment. This mechanism effectively solves the problem of excessive instantaneous acceleration caused by uncontrollable discharge under traditional thyristor drive. It enables smooth deceleration of the switch mechanism, avoids rebound caused by inertial impact on the target position limit structure, and eliminates the potential for poor contact during the instant of switch on and off.

[0017] 2. By standardizing the drive parameters and comprehensively analyzing the motion, force, and current of the switch mechanism, a dynamic balance between the electromagnetic force and the obstructive friction force is ensured. Specifically, a positive drive force provides stable positive acceleration during the acceleration phase, and a negative drive force achieves orderly deceleration during the deceleration phase. The sum of the acceleration and deceleration displacements precisely equals the distance from the initial to the target position. This closed-loop control logic makes the motion of the switch mechanism predictable and controllable, avoiding the motion disturbances caused by the uncontrollable discharge speed in traditional drive methods and significantly improving the stability and reliability of the switch's on-off action.

[0018] 3. By adopting the maximum acceleration drive current as the initial drive current, the system achieves a balance between drive efficiency and safety within production specifications. Furthermore, by actively controlling the timing of current delivery, i.e., the deceleration moment, unnecessary energy consumption is avoided. Compared to traditional thyristor drives that rely on capacitor voltage and inductance to passively determine the discharge process, this system reduces ineffective energy consumption by actively cutting off the current. Furthermore, the fast response characteristics of the insulated gate bipolar transistor further enhance the timeliness of current control, ensuring switching accuracy while optimizing overall drive efficiency.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] It should be noted that, in this document, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include," "comprise," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0024] Example 1: like Figure 1-Figure 2 As shown, an embodiment of the present invention provides a controllable drive control system for an eddy current driven switch, which includes the following specific modules: Central computing and processing module: Acquires driving parameters based on experiments. The driving parameters include the distance from the initial position to the target position of the switch movable mechanism, the friction coefficient on the slide rail, the maximum acceleration driving current, the mass of the switch movable mechanism, the magnetic field strength in the space where the switch movable mechanism is located, and the effective length of the switch movable mechanism in the magnetic field. The eddy current coil generates electromagnetic force to drive the switch movable mechanism to generate sliding displacement, thereby realizing circuit on and off. When the circuit is disconnected, the switch movable mechanism is in the initial position. When the circuit is connected, the switch movable mechanism is in the target position and is attracted by the permanent magnet, so that the switch movable mechanism is held in this position. Therefore, there is a distance between the initial position and the target position. The distance between the initial position and the target position of the switch movable mechanism is measured by a position sensor, such as KTC-D-100. Since the switch mechanism slides on the rail, the friction coefficient on the rail is measured experimentally based on the friction formula. The maximum acceleration drive current is obtained according to production specifications. This current is only used to drive the switch mechanism, not the current of the entire circuit. Using the maximum acceleration drive current within production specifications balances safety and efficiency. The mass of the switch mechanism is obtained using weighing equipment to facilitate subsequent calculations. Using a Tesla meter, such as the WT10A model with an accuracy of 0.001T, the Tesla meter probe is placed close to the switch mechanism position at each measurement point. The magnetic field strength at each point is recorded, and the magnetic field strength of the space where the switch mechanism is located is ultimately fitted. After locating the boundaries of the magnetic field space with the Tesla meter, when the switch mechanism is perpendicular to the magnetic field, the length of the switch mechanism between the two boundaries of the magnetic field space is measured using a distance meter (with an accuracy of 0.1mm) to obtain the effective length. The motion, force and current of the switch movable mechanism are analyzed according to the driving parameters. When the current passes through the eddy current coil, an alternating magnetic field is generated according to the principle of electromagnetic induction. The magnetic field acts on the metal parts of the switch movable mechanism, inducing eddy currents. The eddy currents are acted upon by the Ampere force in the magnetic field, forming an electromagnetic force that drives the switch movable mechanism. After the electromagnetic force overcomes the friction of the slide rail, it drives the movable mechanism to generate acceleration according to Newton's second law, which is then converted into speed and displacement. Therefore, a comprehensive calculation is performed while performing standardization processing to eliminate the dimensional differences of the driving parameters and convert values ​​of different orders of magnitude into a unified numerical range. The deceleration moment of the switch movable mechanism is obtained, recorded as the deceleration moment, to determine the time node for controlling the current delivery, that is, to accurately control the speed of the switch movable mechanism from the initial position to the target position to be zero, and to judge whether the moment of driving the switch movable mechanism reaches the deceleration moment. Sine pulse width modulation signal module: As the signal transfer core, it responds to the instructions of the central computing and processing module in real time. Before the switch mechanism reaches the preset deceleration time, it continuously outputs high-frequency pulse modulation signals to accurately control the conduction state of the conductive channel and ensure a stable and unobstructed current transmission path. When the central computing and processing module determines that the deceleration time has been reached, it immediately switches the signal output mode and issues a cutoff pulse signal to quickly cut off the drive instruction of the conductive channel. Insulated gate bipolar transistor execution switch module: After receiving the turn-on signal, its internal power tube quickly turns on, forming a low-impedance current path, enabling the DC power supply to supply power to the eddy current coil with a stable maximum acceleration drive current, providing continuous driving force for the switching mechanism; and at the moment of receiving the turn-off signal, the power tube is immediately shut down, completely blocking the current transmission path, stopping the supply of current to the eddy current coil, relying on the mechanism's own friction to achieve deceleration, and at the same time triggering the termination mechanism of the control process to ensure that the entire driving process is precise and controllable.

[0025] Example 2 differs from Example 1 in that: The specific method of obtaining the deceleration moment is as follows: According to the maximum acceleration driving current, the magnetic field strength of the space where the switch movable mechanism is located, and the effective length of the switch movable mechanism in the magnetic field, the electromagnetic force is calculated in combination with the Ampere force formula. Since the electromagnetic force needs to make the switch movable mechanism overcome the sliding friction when pushing the switch movable mechanism to move from the initial position to a certain intermediate position, the friction coefficient on the slide rail and the mass of the switch movable mechanism are used, where the friction coefficient is obtained by fitting the static friction coefficient and the dynamic friction coefficient, and the obstruction friction is calculated in combination with the friction formula. When the switch movable mechanism overcomes the obstruction friction under the action of the electromagnetic force, the positive driving force is obtained, and in combination with Newton's second law formula, the positive acceleration of the switch movable mechanism is obtained. The time when the switch movable mechanism moves to this intermediate position is set as the acceleration time. According to the positive acceleration and acceleration time, and in combination with the uniformly accelerated linear motion displacement formula, the accelerated displacement of the switch movable mechanism is calculated. In addition, the acceleration is calculated in combination with the uniformly accelerated linear motion velocity formula. Speed. After this moment, the switch movable mechanism decelerates. In the process of deceleration, the electromagnetic force disappears, overcoming the obstructing friction force and obtaining the counter-driving force. Combined with Newton's second law formula, the reverse acceleration of the switch movable mechanism is obtained. The time when the switch movable mechanism moves from this midway position to the target position is set as the deceleration time. According to the reverse acceleration and deceleration time, combined with the uniformly accelerated linear motion displacement formula, the deceleration displacement of the switch movable mechanism is calculated. In addition, the deceleration speed is calculated by combining the uniformly accelerated linear motion speed formula. Since at this midway position, the switch movable mechanism changes from acceleration to deceleration, that is, the final speed of the switch movable mechanism during acceleration becomes the starting speed during deceleration. Therefore, at this midway position, the acceleration speed is equal to the deceleration speed. The sum of the acceleration displacement of the switch movable mechanism and the deceleration displacement of the switch movable mechanism is equal to the distance from the initial position to the target position of the switch movable mechanism. Therefore, a set of equations is established to calculate the time at this midway position and record it as the deceleration time. ; in, Indicates the acceleration speed, Indicates the deceleration speed, Indicates the accelerated displacement of the switch mechanism, Indicates the deceleration displacement of the switch movable mechanism, Indicates the distance from the initial position to the target position of the switch movable mechanism.

[0026] The specific way to obtain electromagnetic force is as follows: Since the maximum acceleration driving current is not an eddy current, the material coefficient of the switch mechanism is set and calibrated through experiments, and an attenuation function is established. The eddy current induced in the switch mechanism is calculated based on the maximum acceleration driving current, the material coefficient of the switch mechanism and the attenuation function. ;in represents the eddy current induced in the switch mechanism, Indicates the maximum acceleration drive current, Indicates the material coefficient of the switch mechanism, Represents the attenuation function, which is obtained by fitting different displacements measured at equal intervals along the slide rail under specific experimental conditions. The eddy current induced in the corresponding switch mechanism is combined with the maximum acceleration drive current and the material coefficient of the switch mechanism to separate the The linearly varying attenuation portion.

[0027] In the Ampere force formula middle, represents the Ampere force, Indicates the magnetic field strength in the space where the switch mechanism is located, Indicates the maximum acceleration drive current, Indicates the effective length of the switch mechanism in the magnetic field, It represents the angle between the direction of the maximum acceleration driving current in the switch mechanism and the direction of the magnetic field in the space where the switch mechanism is located. However, in engineering design, , which means that the direction of the maximum acceleration driving current in the switch movable mechanism is perpendicular to the direction of the magnetic field in the space where the switch movable mechanism is located, so that the Ampere force is maximized, that is, the electromagnetic force driving the switch movable mechanism is maximized to improve the energy conversion efficiency. Therefore, the default value is , and calculate the electromagnetic force based on the magnetic field strength of the space where the switch movable mechanism is located, the maximum acceleration drive current, and the effective length of the switch movable mechanism in the magnetic field; ; in, represents the electromagnetic force, Indicates the magnetic field strength in the space where the switch mechanism is located, Indicates the maximum acceleration drive current, Indicates the effective length of the switch mechanism in the magnetic field.

[0028] The specific way to obtain the hindering friction is as follows: The pressure exerted by the switch movable mechanism on the slide rail is obtained by multiplying the known gravitational acceleration by the mass of the switch movable mechanism. The hindering friction force is obtained by multiplying the pressure exerted by the switch movable mechanism on the slide rail by the friction coefficient on the slide rail. The hindering friction force is the sliding friction force.

[0030] The specific method of obtaining the reverse driving force is as follows: ; in, Represents the counter-driving force, and the negative sign indicates the negative direction. It represents the hindering friction force. Since the electromagnetic force disappears, the counter-driving force is equal to the sliding friction force. When the sliding friction force is equal to the static friction force, it means that the counter-driving force is equal to zero, that is, the switch movable mechanism reaches the target position.

[0031] The specific method of obtaining the forward acceleration or reverse acceleration is as follows: or ; in, represents the positive acceleration, represents the positive driving force, Indicates the mass of the switch mechanism, represents the reverse acceleration, represents the counter-driving force, where the positive acceleration is in opposite directions to the negative acceleration, and the positive driving force is in opposite directions to the counter-driving force.

[0032] The specific method of obtaining the accelerated displacement of the switch movable mechanism is as follows: ; in, It represents the accelerated displacement of the switch mechanism. Since the original uniformly accelerated linear motion displacement formula contains the product of the initial velocity and the acceleration time, but the initial velocity is zero, the product of the initial velocity and the acceleration time is also zero. represents the positive acceleration, Indicates acceleration time.

[0033] The specific method of obtaining the deceleration displacement of the switch movable mechanism is as follows: ; in, Indicates the deceleration displacement of the switch movable mechanism, Indicates the deceleration speed, Indicates the deceleration time, Indicates reverse acceleration.

[0034] The specific method of obtaining the acceleration speed or deceleration speed is as follows: or ; in, Indicates the acceleration speed, represents the positive acceleration, Represents the acceleration time. Since the speed formula of uniformly accelerated linear motion includes the initial speed, the initial speed is zero during acceleration, and during deceleration, the initial speed is the deceleration speed, and the final speed is zero.

[0035] The specific method for determining whether the moment of driving the switch movable mechanism reaches the deceleration moment is: The moment when the system starts is recorded as the actual start moment, and the current moment is recorded as the actual current moment. The difference between the actual current moment and the actual start moment is calculated to obtain the actual time period. The difference between the deceleration moment and the actual start moment is calculated to obtain the preset time period. The actual time period is compared with the preset time period. If the actual time period is less than the preset time period, it means that the deceleration moment has not been reached. If the actual time period is equal to the preset time period, it means that the deceleration moment has been reached.
