Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0018] Example 1 Figure 1 This is a flowchart of a driver control method provided in Embodiment 1 of the present invention. This embodiment can be applied to controlling drivers, etc. The driver is used to drive devices such as transducers. The control method can be executed by a control module in the driver. The control module can be integrated into an electronic device such as a computer. The control module can be implemented in software and / or hardware. The method specifically includes the following steps: Step 110: Obtain the first operating parameters of the transducer and the second operating parameters of the driver.

[0019] The first operating parameter includes at least one of the transducer's output current and the transducer's output voltage; the second operating parameter includes at least one of the driver's temperature and the driver's voltage. In one embodiment, the first operating parameter includes the transducer's output current and the transducer's output voltage, and the second operating parameter includes the driver's temperature and the driver's voltage.

[0020] Step 120: Control the operating state of the driver according to the first operating parameters, so as to adjust the operating state of the transducer through the driver.

[0021] Specifically, based on the first operating parameters such as the output current and output voltage of the transducer, the parameters required for the driver to drive the transducer, such as frequency, gain, and matching impedance, are determined, and corresponding control commands are generated to control the frequency, gain, and matching impedance of the driver.

[0022] Step 130: Based on the second operating parameters, determine whether the driver is malfunctioning, and if the driver is malfunctioning, control the driver to stop working.

[0023] Specifically, if the second operating parameter, such as the temperature and / or voltage of the driver, exceeds its respective preset threshold, the driver is determined to be abnormal. At this time, the driver is controlled to stop working and stop output to prevent the abnormal driver from affecting the normal operation of the driver and transducer, or even causing damage to the driver and transducer, so as to realize remote fault monitoring and diagnosis.

[0024] The driver control method provided in this embodiment includes: acquiring first operating parameters of the transducer and second operating parameters of the driver; controlling the operating state of the driver according to the first operating parameters to adjust the operating state of the transducer; determining whether the driver is malfunctioning according to the second operating parameters, and controlling the driver to stop working when the driver is determined to be malfunctioning. The driver control method provided in this embodiment controls the operating state of the driver according to the acquired first operating parameters, adjusts the operating state of the transducer through the driver, and determines whether the driver is malfunctioning according to the second operating parameters. When the driver is determined to be malfunctioning, the method controls the driver to stop working, preventing the driver malfunction from affecting the driver and the transducer, thereby improving control reliability.

[0025] Example 2 Figure 2 This is a flowchart of a driver control method provided in Embodiment 2 of the present invention. This embodiment can be applied to controlling drivers, etc. The driver is used to drive devices such as transducers. The control method can be executed by a control module in the driver. The control module can be integrated into an electronic device such as a computer. The control module can be implemented in software and / or hardware. The method specifically includes the following steps: Step 210: Obtain the first operating parameters of the transducer and the second operating parameters of the driver.

[0026] The first operating parameter includes at least one of the transducer's output current and the transducer's output voltage; the second operating parameter includes at least one of the driver's temperature and the driver's voltage. In one embodiment, the first operating parameter includes the transducer's output current and the transducer's output voltage, and the second operating parameter includes the driver's temperature and the driver's voltage.

[0027] Step 220: Based on the first operating parameters, determine the required frequency, gain, and matching impedance of the driver, and generate the corresponding adjustment instructions.

[0028] In one implementation, based on first operating parameters such as the output current and output voltage of the transducer, and using a preset impedance matching algorithm and frequency tracking model, the required frequency, gain, and matching impedance of the driver are calculated, and corresponding adjustment commands are generated.

[0029] Step 230: Control the output signal of the driver based on the adjustment command.

[0030] Specifically, the output signal of the driver is adjusted by means of the command, such as the output signal of the driver corresponding to the required frequency, gain and matching impedance of the driver. This output signal is transmitted to the transducer so that the transducer is in the optimal operating state.

[0031] Step 240: Determine the working efficiency of the transducer based on the first working parameters.

[0032] Specifically, based on the first operating parameters, such as the output current and output voltage of the transducer, the operating efficiency of the transducer at the current moment is determined, and the relationship between the operating efficiency of the transducer at the current moment and the operating efficiency of the transducer at the previous moment is determined.

[0033] Step 250: When the working efficiency of the transducer is lower than the preset threshold, control the driving frequency of the driver to correspond to the target resonant point of the transducer in order to improve the working efficiency of the transducer.

[0034] In one implementation, the driving frequency of the control driver is increased or decreased to match the target resonant point of the transducer, preventing the resonant point of the transducer from shifting. This improves the transducer's efficiency when its operating efficiency is below a preset threshold. Furthermore, when the transducer's current operating efficiency is lower than its previous operating efficiency, the driving frequency of the control driver is adjusted to correspond to the target resonant point of the transducer to further improve its operating efficiency.

[0035] Step 260: When at least one of the second operating parameters exceeds the corresponding preset range, determine that the driver is abnormal and control the driver to stop working.

[0036] Specifically, when at least one of the second operating parameters, such as the temperature of the driver and / or the voltage of the driver, exceeds its respective preset range, the driver is identified as abnormal and the driver is controlled to stop working, so as to prevent the driver and transducer from being affected by the driver abnormality, and at the same time, remote control is realized.

[0037] In addition, during the process of controlling the driver, the control module of the driver uploads the acquired parameters and various information such as the status of the driver and the transducer to the cloud; and when the driver is found to be abnormal, it issues corresponding prompts to notify relevant personnel.

[0038] The driver control method provided in this embodiment adjusts the working state of the transducer by controlling the working state of the driver according to the first working parameters, and determines that the driver is abnormal when at least one of the second working parameters exceeds the corresponding preset range, and controls the driver to stop working to prevent the driver and transducer from being affected by the driver abnormality, thereby improving the control reliability; and the above control process is a remote control process, thereby realizing remote control and remote diagnosis of the driver.

[0039] Example 3 Figure 3 This is a structural block diagram of a driver provided in Embodiment 3 of the present invention. (See reference) Figure 3 The driver includes a control module 10, a frequency synthesis module 20, a differential amplifier module 30, a gain adjustment module 40, a power amplifier module 50, and an impedance matching and optocoupler output module 60. The control module 10 is communicatively connected to the frequency synthesis module 20 and the gain adjustment module 40. The frequency synthesis module 20, the differential amplifier module 30, the gain adjustment module 40, the power amplifier module 50, and the impedance matching and optocoupler output module 60 are electrically connected in sequence. The impedance matching and optocoupler output module 60 is electrically connected to the transducer. The control method of the driver as described in any embodiment of the present invention is executed by the control module. The specific execution process can be referred to in any of the above embodiments, and will not be repeated here.

[0040] Optionally, the driver also includes a sampling module 70, through which the transducer is communicatively connected to the control module 10.

[0041] Specifically, the sampling module 70 is used to collect the output parameters of the transducer, such as output voltage and output current, and transmit the collected parameters to the control module 10 so that the control module 10 can perform corresponding control based on the parameters collected by the sampling module 70.

[0042] In one embodiment, the frequency synthesis module 20 includes a DDS (Direct Digital Synthesizer) chip, the gain adjustment module 40 includes a gain amplifier chip, the differential amplifier module 30 includes a differential amplifier and a pre-driver unit, the power amplifier module 50 includes a power amplifier chip, the control module 10 includes a SOC (System on Chip) chip, and the driver further includes a digital-to-analog converter chip. For example, the DDS chip is model AD9833, the gain amplifier chip is model AD8338, the power amplifier chip is model OPA541, the SOC chip is model ZYNQ, and the digital-to-analog converter chip is model AD5541. The design of ZYNQ + AD9833 + AD8338 + AD5541 + OPA541 is not merely about replacing an analog system with a digital one. Its deeper significance lies in leveraging the control advantages of the ARM processor in ZYNQ and the real-time parallel computing capabilities of the FPGA (Field Programmable Gate Array) in ZYNQ to construct a powerful heterogeneous computing platform. The core value of this platform lies in its ability to build and implement a complete, efficient, accurate, and responsive "perception-decision-execution" technical loop for 120kHz ultrasonic drive applications, from signal sensing and data decision-making to power execution. In the signal sensing stage, the sampling module collects the output voltage and current signals of the transducer in real time and transmits the data synchronously to the ZYNQ FPGA. After the FPGA performs high-speed filtering and amplitude and phase calculation of the signal, it transmits the processing results to the ARM processor. Based on the preset impedance matching algorithm and frequency tracking model, the ARM processor makes parameter decisions based on the real-time sensed signal data, and quickly outputs the adjustment instructions corresponding to the frequency, gain and matching impedance required by the driver. Then, it controls the AD9833 to adjust the frequency of the driver output signal, the AD5541 to adjust the impedance parameters of the matching network, and the AD8338 to adjust the signal gain. Finally, the OPA541 completes the power amplification of the output signal, and the amplified output signal is transmitted to the transducer. The entire closed-loop process can be completed in milliseconds without manual intervention.

[0043] Furthermore, the control module is integrated into electronic devices such as computers and mobile phones, providing remote control capabilities, real-time response, and ease of operation. It supports remote access via Ethernet, Wi-Fi, or dedicated protocols, allowing users to adjust transducer parameters without being physically present, reducing equipment maintenance and debugging time costs. The remote control interface can be seamlessly integrated into host computers or industrial IoT systems for automated scheduling. For example, it can automatically switch transducer operating modes based on sensor feedback, linking with robotic arms and conveyors to improve overall production line efficiency. Security and fault prevention: The control module can incorporate hierarchical access control and encrypted communication to prevent unauthorized operations. Simultaneously, remote diagnostics can monitor driver status such as temperature and voltage in real time, providing early warnings of potential faults and avoiding downtime losses. Full lifecycle traceability: The control module automatically records transducer operating parameters, such as operating voltage, current, output power, and cumulative runtime, as well as event logs such as startup, shutdown, and alarms. The data recorded by the control module can be used to generate historical trend reports, helping users analyze equipment performance degradation patterns and optimize maintenance cycles. The control module can also record the impedance change curve of the transducer during ultrasonic welding, assisting engineers in adjusting process parameters and improving welding consistency. Intelligent Decision-Making Closed Loop: The control module's control of the drive, combined with remote control and data logging, enables a "monitor-analysis-adjustment" closed loop. For example, by recording data, the control module determines a decline in transducer efficiency, automatically and remotely adjusts the drive frequency to the resonant point, restoring the transducer's optimal performance and achieving unattended intelligent operation and maintenance. Reduced Total Cost: Remote control reduces on-site inspection manpower, while data logging avoids unplanned downtime through predictive maintenance. The combination of these two approaches can extend transducer lifespan by more than 30%, significantly reducing spare parts replacement and repair costs. Multi-Scenario Adaptability: Whether for single-unit testing in a laboratory or cluster management in a factory, remote control and data logging can be flexibly expanded. For example, it supports simultaneous monitoring of data from 100+ drives, presented through a visual dashboard, improving management transparency. Furthermore, the control module's control of the driver enables automatic frequency tracking, solving the industry problem of temperature drift and aging in piezoelectric transducers, ensuring that the transducer's efficiency remains constant at 95%+; nanosecond-level digital closed-loop: FPGA hardware PID achieves constant current / constant voltage accuracy of ±1%, which is unattainable by traditional analog circuits; intelligent: from signal generation to power drive to data acquisition to cloud interconnection, an integrated programmable platform is realized, which can also advance the ultrasonic drive of the transducer from the "analog power amplifier" era to the "software-defined ultrasound" era, giving it a clear generational advantage in Industry 4.0 and precision manufacturing.

[0044] Furthermore, the driver's automated process includes power-on self-test, frequency sweep to find the resonant point, lock operation, and real-time monitoring. It is ready to use right out of the box and requires no manual debugging. Data such as drive current, voltage, phase, and temperature are stored in the cloud in real time, enabling traceability analysis, predictive maintenance, and remote data upload. Firmware can be updated remotely, and on-site algorithm iteration can be performed without disassembling the device. Multiple modes, such as sine / triangular / frequency sweep / burst modes, can be switched via software, making it versatile and adaptable to different processes. ZYNQ's FPGA deploys a neural network to identify abnormal resonant modes and upload them to the cloud. With the support of big data, it can provide early warnings of transducer aging / cracks.
