Description

Technical Field

[0001] The present application relates to the technical field of ultrasonic equipment detection, and in particular to an ultrasonic transducer performance monitoring device, method and ultrasonic equipment. Background Art

[0002] Ultrasonic transducers are devices that convert electrical energy into ultrasonic energy within the ultrasonic frequency range. They are widely used in a variety of fields, including ultrasonic testing, cleaning, and imaging. Their performance directly affects the quality, intensity, and spectral characteristics of the ultrasonic output.

[0003] In the prior art, ultrasonic transducer performance monitoring is typically evaluated using offline testing methods. For example, offline measurement equipment such as a vector network analyzer (VNA) or an LCR meter (used to measure inductance L, capacitance C, and resistance R) is used to test the transducer's reflection coefficient or impedance value. Alternatively, specialized instruments are used to test the ultrasonic transducer's waveform or output signal's spectral characteristics to assess its operating status. However, these methods can only test performance data (such as electrical characteristics, waveform, or output signal quality) before operation or under laboratory conditions, and cannot reflect the transducer's operating status (such as workload or internal state) in real time in an actual operating environment. In particular, when the operating status changes (such as load changes or significant temperature changes), the test results are difficult to adjust or correct in a timely manner, and cannot effectively reflect the ultrasonic transducer's operating status in real time.

[0028] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0029] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0030] Figure 1 This is a schematic diagram of the structure of an ultrasonic transducer performance monitoring device provided in an embodiment of the present application. This embodiment is applicable to ultrasonic equipment performance monitoring and management in industrial and medical fields, and is particularly suitable for high-frequency operations and applications with high requirements for ultrasonic output quality. Types of ultrasonic transducers include, but are not limited to, transducers for ultrasonic therapy, ultrasonic diagnostics, industrial inspection, and ultrasonic cleaning.

[0031] like Figure 1 As shown, the ultrasonic transducer performance monitoring device of the present application includes: an acquisition module 100 , a signal processing module 200 and a performance analysis module 300 .

[0032] The acquisition module 100 of the present application is used to collect electrical parameters and temperature data from an ultrasonic transducer. Electrical parameters can be understood as those that directly impact the transducer's performance and application effectiveness. Typically, these parameters include, but are not limited to, the frequency (e.g., up to several megahertz) of the transducer's drive circuit during actual operation, voltage, current, and ultrasonic amplitude. The ultrasonic transducer's temperature data can be understood as the temperature of the transducer's piezoelectric element. Specifically, a voltage detection element (e.g., a voltage sensor, potentiometer, voltmeter, or voltage detection chip), a current detection element (e.g., a current sensor, current transformer, or sampling resistor), and a temperature detection element (e.g., a thermocouple or temperature sensor) can be provided in the ultrasonic transducer's drive circuit. The voltage detection element can be used to collect the real-time voltage of the ultrasonic transducer at any moment during actual operation, or the average voltage over any time period. The current detection element can be used to collect the real-time current of the ultrasonic transducer at any moment during actual operation, or the average current over any time period. A temperature sensor is mounted on the surface of the ultrasonic transducer's piezoelectric element to collect the real-time temperature of the piezoelectric element at any moment during the transducer's actual operation, or the average temperature over any time period. In some embodiments, an insulating member may be provided between the temperature sensor and the piezoelectric element to prevent signal crosstalk between the elements, thereby improving system reliability and data acquisition accuracy.

[0033] The signal processing module 200 of the present application is configured to perform at least one of the following on electrical parameters: signal conversion, power calculation, and effective value calculation, and output a first processing result; and to perform at least one of the following on temperature data: signal conversion and temperature calculation, and output a second processing result. In the present application, signal conversion includes at least analog-to-digital conversion. Specifically, the current data, voltage data, and temperature data of the present application may be analog signals. Through signal conversion, the analog signals are converted into digital signals, which are then stored or used for subsequent calculations. For example, temperature data (analog signal) may be converted into operating temperature (digital signal). In some embodiments, power calculation on electrical parameters includes filtering, compensation, pre-attenuation, phase shifting, and calibration (including but not limited to phase calibration and offset calibration) on voltage and current, and performing active power, reactive power, and power factor calculations based on the data processing results. Specifically, the signal processing module 200 can simultaneously calculate active power and reactive power based on measured electrical parameters (such as voltage and current), and calculate the power factor based on the active power and reactive power. Correspondingly, the first processing result includes, but is not limited to, at least one of the following: power data, voltage RMS, and current RMS. The power data includes, but is not limited to, active power, reactive power, and power factor. The second processing result includes, but is not limited to, at least one of the following: operating temperature and temperature rise rate. In some embodiments, performing RMS calculation processing on the electrical parameters includes filtering and pre-attenuating the voltage and current data, and performing RMS calculation based on the data processing results (for example, using an analog RMS conversion circuit to perform square value calculation, integration calculation, division calculation, square root calculation, etc. based on the processing results of the voltage and current data).

[0034] The performance analysis module 300 of the present application is used to perform a multi-parameter fusion analysis of the working state of the ultrasonic transducer based on the first processing result and the second processing result. When the analysis result shows that the working state is abnormal, an early warning message is issued, and the working parameters of the ultrasonic transducer are adjusted or the ultrasonic transducer is shut down. The working state can be understood as the state of the energy conversion and mechanical vibration characteristics of the ultrasonic transducer. Typically, the working state can be reflected in at least one of the following data: electroacoustic conversion efficiency, aging degree, reflection of driving electric power, load rate, and temperature rise change.

[0035] In this embodiment, multi-parameter fusion analysis can be understood as an operating state analysis method based on the corresponding relationship between power data, temperature data, voltage data, current data, and the operating state of the ultrasonic transducer. For example, the power factor can reflect the electroacoustic conversion efficiency of the transducer, while the temperature rise change can reveal the load condition and potential failure risk of the transducer. In some embodiments, a multi-parameter fusion analysis of the operating state of the ultrasonic transducer is performed based on the first processing result and the second processing result, including but not limited to: identifying the electroacoustic conversion efficiency, aging degree, load rate, reflection of driving electric power, and potential equipment failure of the transducer piezoelectric element based on a comprehensive analysis of voltage data (such as voltage RMS), current data (such as current RMS), power data (such as power factor), and temperature data (such as temperature rise rate and operating temperature).

[0036] The operating parameters of an ultrasonic transducer can be understood as data associated with the operating state of the ultrasonic transducer. Typically, these parameters include, but are not limited to, output power, drive voltage, drive current, and load. In this embodiment, when an abnormality occurs in the operating state, a warning message is issued and the operating parameters of the ultrasonic transducer are adjusted or the ultrasonic transducer is shut down. These include, but are not limited to, increasing the output power of the transducer when the electroacoustic conversion efficiency is low (e.g., below a preset conversion efficiency threshold); and reducing the load of the transducer when the load rate is high (e.g., above a preset load threshold).

[0037] Specifically, by collecting multiple data points from the transducer, such as voltage, current, and temperature, in real time, the active and reactive power are calculated based on the measured voltage and current data, and the power factor is further calculated. By analyzing the changes in power, temperature, voltage, and current in real time, the health of the transducer can be dynamically and continuously monitored. This facilitates the early detection of potential faults or operating anomalies, improves the operating stability of the ultrasonic transducer, and avoids damage or failure due to overheating or performance degradation. By establishing a multi-parameter fusion analysis method, a comprehensive analysis of data such as power, temperature, voltage, and current is performed to identify the electroacoustic conversion efficiency, aging level, load factor, reflection of the driving power, and potential equipment failures of the transducer's piezoelectric element. The cause of the anomaly is precisely located, and the transducer's operating parameters are adjusted accordingly, avoiding the limitations of single-parameter monitoring. This helps accurately assess the ultrasonic output quality of the ultrasonic transducer and ensure that the ultrasonic intensity and spectrum meet actual application requirements. Through intelligent feedback and fault warning, timely anomaly warnings can be issued and the transducer can be adaptively controlled, greatly improving the device's self-protection capabilities and reliability.

[0038] Optionally, Figure 2 This is a schematic diagram of the structure of another ultrasonic transducer performance monitoring device provided in an embodiment of the present application. Figure 1Based on the embodiment shown, a specific implementation of a performance analysis module is shown. Figure 2 In the embodiment shown, the signal processing module 200 is used to perform power calculation processing on the electrical parameters, and the corresponding first processing result output is the power factor; the signal processing module 200 is also used to perform signal conversion processing on the temperature data, and the corresponding second processing result output is the operating temperature. Figure 2 As shown, the performance analysis module 300 of the present application includes at least one of the following: a first analysis submodule 310, a second analysis submodule 320 and a third analysis submodule 330. The multiple analysis submodules work in parallel, which can improve the analysis efficiency and response speed, and the response speed can be increased to millisecond level.

[0039] The first analysis submodule 310 of the present application is configured to adjust the output power of the ultrasonic transducer when the power factor is lower than a first power factor threshold and the operating temperature is lower than a preset temperature threshold, and determine whether an abnormal acoustic-to-electrical conversion caused by a device failure has occurred based on the output power adjustment result. The first power factor threshold is the lower limit of the power factor that satisfies the matching between the transducer and the ultrasonic generator and the output performance of the transducer. When the power factor is greater than or equal to the first power factor threshold, the electro-acoustic conversion efficiency of the ultrasonic transducer is normal. For example, the first power factor threshold can be set to any value greater than or equal to 0.5 and less than or equal to 1, such as 0.6, 0.7, or 0.8. It should be noted that the closer the power factor is to 1, the higher the electro-acoustic conversion efficiency. The preset temperature threshold is the upper temperature limit that ensures the normal operation of the piezoelectric element in the transducer. For example, the preset temperature threshold can be set to any value greater than or equal to 45°C and less than or equal to 75°C, such as 50°C, 60°C, or 70°C. Specifically, if the power factor is lower than the first power factor threshold (for example, 0.6) and the transducer temperature is normal, it means that the current electro-acoustic conversion efficiency is low, and the output power of the ultrasonic transducer is adjusted to increase the output power. If the power factor is still not ideal after increasing the output power, it is determined that the acoustic-to-electrical conversion abnormality has occurred due to equipment failure, and the transducer is controlled to shut down.

[0040] Furthermore, the first analysis submodule 310 of the present application is also configured to: when the adjusted output power reaches a preset power value and the power factor corresponding to the preset power value is lower than a first power factor threshold, issue a first fault troubleshooting warning. The preset power value is greater than or equal to the rated output power of the ultrasonic transducer. Specifically, if the output power reaches the preset power value and the power factor corresponding to the preset power value is lower than the first power factor threshold, it is determined that an abnormal acoustic-to-electrical conversion caused by equipment failure has occurred. By issuing the first fault troubleshooting warning, the operator is reminded that the energy conversion efficiency of the ultrasonic transducer is low and to check whether there is any damage or aging of the components.

[0041] The second analysis submodule 320 of the present application is configured to: when the power factor is greater than or equal to the first power factor threshold and the operating temperature is greater than or equal to the preset temperature threshold, perform a load test on the ultrasonic transducer, and determine whether the ultrasonic transducer has an overload abnormality based on the load test result. Specifically, when the power factor range is greater than or equal to the first power factor threshold (for example, any value greater than or equal to 0.6 and less than or equal to 1), and the operating temperature is greater than or equal to the preset temperature threshold, perform a load test on the ultrasonic transducer. If the load is too large (for example, greater than the rated load * 120%), if the load is normal, it is determined that the temperature rise is caused by the ultrasonic transducer overload, and the workload of the transducer is reduced or the transducer is controlled to shut down.

[0042] Furthermore, the second analysis submodule 320 of the present application is further configured to issue a second fault troubleshooting warning when the ultrasonic transducer does not experience an overload anomaly and the operating temperature remains greater than or equal to a preset temperature threshold for a preset duration (e.g., 10ms). The preset duration is based on the average monitoring time for temperature changes in the piezoelectric element in the ultrasonic transducer under normal equipment operation (no overload and no equipment anomalies). This preset duration is greater than the delay time for the piezoelectric element to operate. Specifically, the second fault troubleshooting warning is used to alert the operator to abnormal heating of the ultrasonic transducer and to check for component damage or aging.

[0043] In some embodiments, the third analysis submodule 330 of the present application is configured to determine that an abnormal temperature rise has occurred in the ultrasonic transducer when the power factor is lower than a first power factor threshold and the operating temperature is greater than or equal to a preset temperature threshold. Specifically, if the power factor is lower than the first power factor threshold (e.g., 0.6) and the transducer temperature exceeds a preset temperature threshold (e.g., 60°C), this indicates low electroacoustic conversion efficiency and severe transducer heating. The transducer is then controlled to reduce heating, for example, by reducing the transducer's output power or operating frequency, to ensure transducer safety.

[0044] Therefore, the multi-parameter fusion analysis method of the present application conducts a comprehensive analysis of the power data and temperature data. If the power factor is normal and the operating temperature is within a safe range, the ultrasonic transducer is determined to be operating normally; if the power factor is low or the operating temperature is abnormal, the ultrasonic transducer is determined to be operating abnormally, the cause of the abnormality is accurately located, and the operating parameters of the transducer are adjusted accordingly, avoiding the limitations brought by single parameter monitoring, and avoiding equipment failures or unqualified ultrasonic output quality caused by factors such as temperature rise or power factor changes. It helps to accurately evaluate the ultrasonic output quality of the ultrasonic transducer and ensure that the ultrasonic intensity and spectrum meet the actual application requirements.

[0045] Optionally, Figure 3A schematic diagram of the structure of another ultrasonic transducer performance monitoring device provided in an embodiment of the present application, Figure 1 Based on the embodiment shown, a specific implementation of an acquisition module is shown, which is suitable for high-frequency circuit application scenarios. In this embodiment, the electrical parameters include current data and voltage data of the ultrasonic transducer; the first processing result includes active power, reactive power and power factor. Figure 3 As shown, the acquisition module 100 of the present application includes a high-frequency current detection unit 110 and a high-frequency voltage detection unit 120. The high-frequency current detection unit 110 is used to collect current data flowing through the ultrasonic transducer at any time or in any time period, and the high-frequency voltage detection unit 120 is used to collect voltage data of the ultrasonic transducer at any time or in any time period; the signal processing module 200 is configured to calculate active power based on current data and voltage data, calculate reactive power based on current data and voltage data, and calculate power factor based on active power and reactive power.

[0046] Specifically, in high-frequency circuits (such as those with an operating frequency of 5 to 10 MHz), the waveforms corresponding to the voltage data and current data change rapidly, and the difficulty and error in calculating the power factor based on the phase difference between the voltage data and the current data are relatively large. The active power and reactive power of the transducer can be calculated synchronously based on the voltage data, current data and parallel signal processing circuits, and the power factor can be calculated based on the active power and reactive power, avoiding the calculation of the phase difference between the voltage and current, thereby reducing the calculation difficulty and error.

[0047] For example, active power is defined as P, reactive power is defined as Q, voltage data is defined as u, current data is defined as i, and power factor is defined as , the active power P is calculated using the following formula:

[0048] (Formula 1)

[0049] in, Indicates the real-time dynamic value of active power P; Represents the inherent phase difference between voltage and current. In a sinusoidal AC circuit, this phase difference can be determined by measuring the voltage and current waveforms without calculation.

[0050] The reactive power Q is calculated using the following formula 2:

[0051] (Formula 2)

[0052] in, Indicates the real-time dynamic value of reactive power Q; Represents the inherent phase difference between voltage and current. In a sinusoidal AC circuit, this phase difference can be determined by measuring the voltage and current waveforms without calculation.

[0053] The power factor is calculated using the following formula:

[0054] (Formula 3)

[0055] Therefore, combined with the above formulas 1 to 3, the active power P and reactive power Q in formula 3 are calculated synchronously based on voltage data, current data and parallel signal processing circuits, rather than being calculated based on the phase difference between current and voltage. The active power and reactive power of the transducer can be calculated quickly and accurately, and then the power factor is calculated, avoiding the calculation of the phase difference between voltage and current. This can reduce the calculation difficulty and calculation error, improve the calculation accuracy, and improve the performance monitoring response speed and detection accuracy.

[0056] Optionally, the high-frequency current detection unit 110 includes a first housing and a first sensor body disposed within the first housing. The first housing is used to shield the first sensor body from high-frequency interference signals. The high-frequency voltage detection unit 120 includes a second housing and a second sensor body disposed within the second housing. The second housing is used to shield the second sensor body from high-frequency interference signals. Specifically, the first and second housings can be formed from low-resistivity metal materials (such as copper, aluminum, etc.). Under the influence of a high-frequency electromagnetic field, eddy currents are generated in the housings, thereby offsetting external electromagnetic waves, shielding high-frequency interference signals, and improving the detection signal quality of high-frequency circuits (e.g., circuit frequencies reaching 5-10 MHz). Response times can reach milliseconds.

[0057] Figure 4 This is a schematic diagram of the circuit topology of an ultrasonic transducer performance monitoring device provided in an embodiment of the present application. Figure 4As shown, the signal processing module 200 of the present application includes an active power calculation circuit 210 and a reactive power calculation circuit 220 operating in parallel. A first end of the active power calculation circuit 210 is connected to the high-frequency current detection unit 110, and a second end of the active power calculation circuit 210 is connected to the high-frequency voltage detection unit 120. The active power calculation circuit 210 is configured to perform phase calibration on the current and voltage data received by the active power calculation circuit 210 and calculate active power based on the calibrated data. A first end of the reactive power calculation circuit 220 is connected to the high-frequency current detection unit 110 via a phase shift circuit 202, and a second end of the reactive power calculation circuit 220 is connected to the high-frequency voltage detection unit 120. Alternatively, a first end of the reactive power calculation circuit 220 is connected to the high-frequency voltage detection unit 120 via a phase shift circuit 202, and a second end of the reactive power calculation circuit 220 is connected to the high-frequency current detection unit 110 (not shown). The reactive power calculation circuit 220 is configured to perform phase shifting on any one of the current data or voltage data received by the reactive power calculation circuit 220 , perform phase calibration on the phase-shifted data, and calculate reactive power based on the calibrated data.

[0058] See also Figure 4 As shown, the active power calculation circuit 210 includes a first multiplier 201. The reactive power calculation circuit 220 includes a phase shift circuit 202 and a second multiplier 203. The phase shift circuit 202 is electrically connected between the second multiplier 203 and the current signal output terminal of the high-frequency current detection unit 110, or alternatively, between the second multiplier 203 and the voltage signal output terminal of the high-frequency voltage detection unit 120. The first multiplier 201 is used to calculate the active power of the ultrasonic transducer, and the second multiplier 203 is used to multiply the real-time current data and the real-time voltage data after a 90° phase shift to obtain the reactive power of the ultrasonic transducer. In some embodiments, the phase shift circuit designed in this application utilizes precision electronic components for precise phase shifting. In some embodiments, the multiplier in this application incorporates a phase calibration function to calibrate for sampling deviations caused by asynchronous sampling of real-time current and voltage data.

Figure 7As shown, the signal processing module 200 of the present application also includes an effective value calculation circuit 230 and / or a temperature signal processing circuit 240. The input of the temperature signal processing circuit 240 is connected to the temperature detection unit 130, and the output of the temperature signal processing circuit 240 is connected to the performance analysis module 300. The temperature signal processing circuit 240 is configured to calculate the temperature rise rate based on temperature data, such as temperature data at a first moment, temperature data at a second moment, and the interval between the first and second moments. The input of the effective value calculation circuit 230 is connected to the high-frequency current detection unit 110 or the high-frequency voltage detection unit 120, and is configured to perform root mean square (RMS) conversion on electrical parameters (such as real-time current and real-time voltage) to obtain RMS conversion results, and transmit the RMS conversion results to the performance analysis module 300. The performance analysis module 300 is further configured to monitor the operating status based on the RMS conversion results of the electrical parameters and / or the temperature rise rate. Specifically, the RMS value of the current is calculated by RMS conversion of the current data, and the RMS value of the voltage is calculated by RMS conversion of the voltage data. This allows the operator to determine whether the current and voltage of the ultrasonic transducer are normal.
