Description

Technical Field

[0002] Ultrasonic transducers are devices that convert electrical energy into ultrasonic energy within the ultrasonic frequency range. They are widely used in many fields such as ultrasonic detection, cleaning, and imaging. Their working performance directly affects the quality, intensity, and spectrum characteristics of ultrasonic output.

[0003] In the prior art, the performance monitoring of ultrasonic transducers is usually evaluated by offline testing, for example, the reflection coefficient or impedance value of the transducer is tested by offline measuring equipment such as a vector network analyzer (VNA), an LCR tester (used to measure inductance L, capacitance C, and resistance R), or the waveform of the ultrasonic transducer or the spectrum characteristics of the output signal are tested by a special instrument to evaluate its working state. However, the above methods can only test the performance data (such as electrical characteristics, waveform or output signal quality) before work or under laboratory conditions, and cannot reflect the working state of the transducer in the actual working environment (such as workload or internal state) in real time.

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

[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 can be applied to the performance monitoring and management of ultrasonic equipment in the fields of industry and medical treatment, and is particularly suitable for high-frequency operations and application scenarios with high requirements for ultrasonic output quality. The types of ultrasonic transducers include but are not limited to transducers for ultrasonic therapy, transducers for ultrasonic diagnosis, ultrasonic transducers for industrial detection, and transducers for 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 the electrical parameters and temperature data of the ultrasonic transducer. Among them, the electrical parameters can be understood as electrical parameters that directly affect the performance and application effect of the transducer. Typically, the electrical parameters of the ultrasonic transducer include but are not limited to the frequency (for example, up to several megahertz), voltage, current and ultrasonic amplitude of the driving circuit of the transducer during actual operation. The temperature data of the ultrasonic transducer can be understood as the temperature of the piezoelectric element of the ultrasonic transducer. Specifically, a voltage detection element (such as a voltage sensor, a potentiometer, a voltmeter, a voltage detection chip), a current detection element (such as a current sensor, a current transformer or a sampling resistor) and a temperature detection element (such as a thermocouple or a temperature sensor) can be set in the driving circuit of the ultrasonic transducer, and the real-time voltage at any time during the actual operation of the ultrasonic transducer, or the average voltage in any time period, is collected through the voltage detection element. The real-time current at any time during the actual operation of the ultrasonic transducer, or the average current in any time period, is collected through the current detection element. A temperature detection element is installed on the surface of the piezoelectric element of the ultrasonic transducer to collect the real-time temperature of the piezoelectric element at any time during the actual operation of the ultrasonic transducer, or the average temperature within any time period. In some embodiments, an insulating portion may be provided between the temperature detection element and the piezoelectric element to avoid signal crosstalk between the elements, thereby improving the reliability of system operation and the accuracy of data collection.

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

[0034] The performance analysis module 300 of the present application is used to perform a multi-parameter fusion analysis on the working state of the ultrasonic transducer based on the first processing result and the second processing result, and when the analysis result shows that the working state is abnormal, issue a warning message, and adjust the working parameters of the ultrasonic transducer or control the ultrasonic transducer to shut down. Among them, 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, the multi-parameter fusion analysis can be understood as a working state analysis method based on the corresponding relationship between power data, temperature data, voltage data, current data and the working state of the ultrasonic transducer. For example, the power factor can reflect the electroacoustic conversion efficiency of the transducer, and the temperature rise change can reveal the load condition and potential failure risk of the transducer. In some embodiments, a multi-parameter fusion analysis is performed on the working state of the ultrasonic transducer based on the first processing result and the second processing result, including but not limited to: based on the comprehensive analysis of voltage data (such as voltage effective value), current data (such as current effective value), power data (such as power factor) and temperature data (such as temperature rise rate and working temperature), the electroacoustic conversion efficiency, aging degree, load rate, reflection of driving electric power and potential equipment failure of the piezoelectric element of the transducer are identified.

[0036] The working parameters of the ultrasonic transducer can be understood as data associated with the working state of the ultrasonic transducer. Typically, the working parameters of the ultrasonic transducer include, but are not limited to, output power, driving voltage, driving current, and load. In this embodiment, when there is an abnormality in the working state, an early warning message is issued, and the working parameters of the ultrasonic transducer are adjusted or the ultrasonic transducer is controlled to shut down, including but not limited to: when the electroacoustic conversion efficiency is low (for example, lower than a preset conversion efficiency threshold), the output power of the transducer is increased; when the load rate is high (for example, higher than a preset load threshold), the load of the transducer is reduced.

[0037] Specifically, by collecting various data such as voltage, current, and temperature of the transducer in real time, calculating active power and reactive power based on the measured voltage and current data, and further calculating the power factor, the changes in power, temperature, voltage, and current are analyzed in real time, and the health of the transducer can be monitored dynamically and continuously, which is conducive to early detection of potential faults or abnormal working conditions, improving the working stability of the ultrasonic transducer, and avoiding damage or failure of the equipment 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 degree, load rate, reflection of driving electric power, and potential equipment failures of the transducer piezoelectric element, accurately locate the cause of the abnormality, and adjust the working parameters of the transducer accordingly, avoiding the limitations brought by single parameter monitoring, which 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. Through intelligent feedback and fault warning, abnormal warnings can be issued in time, and the transducer can be adaptively controlled, which greatly improves the self-protection ability and reliability of the equipment.

[0038] Optionally, Figure 2 A schematic diagram of the structure of another ultrasonic transducer performance monitoring device provided in an embodiment of the present application, in 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 milliseconds.

[0039] The first analysis submodule 310 of the present application is configured to: when the power factor is lower than the first power factor threshold and the operating temperature is lower than the preset temperature threshold, adjust the output power of the ultrasonic transducer, and determine whether the acoustic-to-electric conversion abnormality caused by the equipment failure occurs according to the output power adjustment result. Among them, 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. Exemplarily, 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 to ensure the normal operation of the piezoelectric element in the transducer. Exemplarily, the preset temperature threshold can be set to any value greater than or equal to 45 and less than or equal to 75°C, such as 50, 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-electric conversion abnormality is caused by 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 issue a first fault troubleshooting warning 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. 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-electric conversion caused by an equipment failure has occurred. By issuing a first fault troubleshooting warning, the operator is reminded that the energy conversion efficiency of the ultrasonic transducer is low and to check whether there are any components that are damaged or aged.

[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 load detection on the ultrasonic transducer, and determine whether the ultrasonic transducer is overloaded according to the load detection 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 load detection 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 overload of the ultrasonic transducer, 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 also configured to issue a second fault troubleshooting warning when the ultrasonic transducer does not have an overload anomaly and the operating temperature continues to be greater than or equal to a preset temperature threshold within a preset time (for example, 10ms). The preset time is established based on the average monitoring time of the temperature change of the piezoelectric element in the ultrasonic transducer under normal operating conditions of the equipment (no overload and no abnormality in the equipment). The preset time is greater than the delay time of the piezoelectric element action. Specifically, the second fault troubleshooting warning is used to remind the operator that the ultrasonic transducer is abnormally hot and to check whether there is damage or aging of components.

[0043] In some embodiments, the third analysis submodule 330 of the present application is configured to: when the power factor is lower than the first power factor threshold and the operating temperature is greater than or equal to the preset temperature threshold, determine that the ultrasonic transducer has an abnormal temperature rise. Specifically, if the power factor is lower than the first power factor threshold (such as 0.6) and the transducer temperature exceeds the preset temperature threshold (such as 60°C), it means that the electroacoustic conversion efficiency is low and the transducer is seriously heated. The transducer is controlled to reduce the heat, for example, the output power or operating frequency of the transducer is reduced to ensure the safety performance of the transducer.

[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 a collection 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 the 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 synchronously calculated based on the voltage data, current data and a parallel signal processing circuit, and the power factor can be calculated based on the active power and reactive power, thereby avoiding calculating the phase difference between the voltage and the current, thereby reducing the difficulty and error of the calculation.

[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 obtained by measuring the waveforms of voltage and current 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 obtained by measuring the waveforms of voltage and current without calculation.

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

[0054] (Formula 3)

[0055] Therefore, in combination 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 can be 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 shell and a first sensor body disposed in the first shell, and the first shell is used to shield the high-frequency interference signal of the first sensor body. The high-frequency voltage detection unit 120 includes a second shell and a second sensor body disposed in the second shell, and the second shell is used to shield the high-frequency interference signal of the second sensor body. Specifically, the first shell and the second shell can be prepared and formed using low-resistivity metal materials (such as copper, aluminum, etc.), and under the action of the high-frequency electromagnetic field, eddy currents are generated in the shells, thereby forming a counteracting effect on external electromagnetic waves, shielding high-frequency interference signals, and improving the detection signal quality of high-frequency circuits (for example, circuit frequencies reach 5-10 MHz), and the response time can reach milliseconds.

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 working in parallel. Among them, the first end of the active power calculation circuit 210 is connected to the high-frequency current detection unit 110, and the 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 used to perform phase calibration on the current data and voltage data received by the active power calculation circuit 210, and calculate the active power according to the calibrated data. The first end of the reactive power calculation circuit 220 is connected to the high-frequency current detection unit 110 via the phase shift circuit 202, and the second end of the reactive power calculation circuit 220 is connected to the high-frequency voltage detection unit 120; or, the first end of the reactive power calculation circuit 220 is connected to the high-frequency voltage detection unit 120 via the phase shift circuit 202, and the second end of the reactive power calculation circuit 220 is connected to the high-frequency current detection unit 110 (not shown in the figure). The reactive power calculation circuit 220 is used to phase-shift any one of the current data or the 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.
