[0037] In order to enable those skilled in the art to better understand this solution, the following will clearly describe the technical solutions in the embodiments of this solution in conjunction with the accompanying drawings in the embodiments of this solution. Obviously, the described embodiments are some, rather than all, of the embodiments of this solution. Based on the embodiments in this solution, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this solution.

[0038] The term "including" and any other variations in the description and claims of this solution and the above accompanying drawings mean "including but not limited to", intending to cover non-exclusive inclusion and not limited to the examples listed in the text. In addition, terms such as "first" and "second" are used to distinguish different objects rather than to describe a specific order.

[0039] The following will describe the implementation of the present disclosure in detail in conjunction with specific accompanying drawings:

[0040] Figure 1 is the structural block diagram of a high-frequency pulse signal detection circuit provided by an embodiment of the present disclosure. Refer to Figure 1, the high-frequency pulse signal detection circuit includes: a processor, a pulse amplitude detection module, a current detection module, a frequency detection module, and a communication module; the first end of the pulse amplitude detection module is used to connect to the high-frequency pulse signal, and the second end of the pulse amplitude detection module is connected to the processor; the current detection module is used to detect the current of the high-frequency pulse signal, and the current detection module is connected to the processor; the first end of the frequency detection module is used to connect to the high-frequency pulse signal, and the second end of the frequency detection module is connected to the processor; the processor is communicatively connected to the terminal through the communication module.

[0041] In this embodiment, the first end of the pulse amplitude detection module is directly connected to the high-frequency pulse signal emitted by the intense pulsed light therapeutic instrument.

[0042] The pulse amplitude detection module measures the amplitude of the high-frequency pulse signal and sends this data to the processor. Ensure that the pulsed light energy output by the therapeutic instrument meets the preset standard, thereby ensuring the treatment effect and safety.

[0043] At the same time, the current detection module monitors the current situation of the high-frequency pulse signal and sends the current data to the processor. This helps to judge whether the working state of the therapeutic instrument is normal and promptly discover possible problems.

[0044] The frequency detection module measures the frequency of the high-frequency pulse signal and sends the result to the processor. In intense pulsed light therapy, the frequency of the pulsed light is an important parameter that affects the treatment effect and the patient's experience.

[0045] After receiving the data from each detection module, the processor will perform comprehensive analysis to judge whether the high-frequency pulse signal meets the treatment requirements. The processor is communicatively connected to the terminal (such as a doctor workstation, a control system, etc.) through the communication module, and real-time feedbacks the analysis result and the working state of the therapeutic instrument to the medical staff.

[0046] As Figure 2 shown, in an exemplary embodiment of the present disclosure, the pulse amplitude detection module includes: a resistor R1, an amplifier U1, a diode D1, a capacitor C1, a triode Q1, and a resistor R3; the first end of the resistor R1 is used to connect to the high-frequency pulse signal, the second end of the resistor R1 is connected to the non-inverting input terminal of the amplifier U1, the output terminal of the amplifier U1 is connected to the anode of the diode D1, the cathode of the diode D1 is grounded through the capacitor C1, the cathode of the diode D1 is connected to the inverting input terminal of the amplifier U1, the cathode of the diode D1 is connected to the base of the triode Q1, the collector of the triode Q1 is connected to the VCC power supply, the emitter of the triode Q1 is grounded through the resistor R3, and the emitter of the triode Q1 is connected to the processor.

[0047] In this embodiment, the pulse amplitude detection module is used to detect the pulse signal generated when the intense pulsed light therapy instrument works. This pulse signal is applied to the non-inverting input terminal of the amplifier U1 after passing through the resistor R1. The amplifier U1 forms a follower, which is used to increase the input impedance of the pulse amplitude detection to reduce the energy of the pulse signal absorbed when the pulse signal is connected to the pulse amplitude detection module, ensuring the effectiveness of the measured pulse signal.

[0048] The diode D1 and the capacitor C1 constitute a peak detection circuit. When the voltage of the capacitor C1 is equal to zero in the initial state, when the pulse signal is at a high level, since the amplifier U1 acts as a follower, the diode D1 conducts. At this time, the high-level voltage charges the capacitor C1 through the diode D1 until the voltage on the capacitor C1 is equal to the peak value when the pulse signal is at a high level. At this time, as long as the voltage of the pulse signal at a high level is less than or equal to the voltage across the capacitor C1, the diode D1 is cut off, and the voltage across the capacitor C1 remains unchanged, that is, the voltage across the capacitor will maintain the peak value of the previously detected voltage. Only when the amplitude of the pulse signal at a high level is greater than the current voltage across the capacitor C1, the diode D1 conducts, and then the capacitor C1 is charged again. In short, the voltage of the capacitor C1 always maintains the peak value of the input voltage.

[0049] When the charging voltage of the capacitor C1 is greater than the conduction voltage of the triode Q1, the triode Q1 conducts, and the triode Q1 operates in the amplification state. After the triode Q1 conducts, a voltage signal is generated on the resistor R3. When the amplitude of the pulse signal remains unchanged, the voltage on the resistor R3 will not change. When the amplitude of the pulse signal changes, the voltage on the resistor R3 will also change. The voltage on the resistor R3 is sent to the processor, and the processor determines whether the pulse signal is stable based on the voltage on the resistor R3, thereby judging the treatment effect of the intense pulsed light therapy instrument.

[0050] As Figure 2 shown, in an exemplary embodiment of the present disclosure, the pulse amplitude detection module further includes: a resistor R4, an amplifier U2, a resistor R5, a resistor R6, and a resistor R7; the first end of the resistor R4 is connected to the emitter of the triode Q1, the second end of the resistor R4 is connected to the non-inverting input terminal of the amplifier U2, the inverting input terminal of the amplifier U2 is connected to the cathode of the diode D1 through the resistor R6, the output terminal of the amplifier U2 is connected to the inverting input terminal of the amplifier U2 through the resistor R5, and the output terminal of the amplifier U2 is connected to the second end of the resistor R1 through the resistor R7.

[0051] To ensure the accuracy of detecting the amplitude of the detection pulse signal, in this embodiment, a compensation circuit is added. The compensation circuit consists of resistor R4, amplifier U2, resistor R5, resistor R6, and resistor R7. The compensation circuit subtracts the voltage signal on resistor R3 from the input pulse signal to compensate for the loss of the measurement pulse amplitude caused by the leakage of diode D1. Thus, the detection accuracy of the pulse signal amplitude is improved.

[0052] As Figure 2 shown, in an exemplary embodiment of the present disclosure, the pulse amplitude detection module further includes: resistor R8 and switching transistor Q2; the first end of resistor R8 is connected to the processor, the second end of resistor R8 is connected to the control end of switching transistor Q2, the first end of switching transistor Q2 is connected to the cathode of diode D1, and the second end of switching transistor Q2 is grounded.

[0053] In this embodiment, resistor R8 and switching transistor Q2 form a discharge circuit. When the detection of the pulse amplitude this time is completed, the processor sends a high-level signal to the control end of switching transistor Q2, and switching transistor Q2 conducts, providing a discharge path for capacitor C1 to ensure normal operation during the next pulse amplitude detection.

[0054] As Figure 3 shown, in an exemplary embodiment of the present disclosure, the frequency detection module includes: resistor R10, resistor R11, amplifier U3, resistor R12, and triode Q3; the first end of resistor R10 is connected to the VDD power supply, the second end of resistor R10 is grounded through resistor R11, the second end of resistor R10 is connected to the non-inverting input terminal of amplifier U3, the inverting input terminal of amplifier U3 is used to connect the high-frequency pulse signal, the output terminal of amplifier U3 is connected to the base of triode Q3, the collector of triode Q3 is connected to the VCC power supply through resistor R12, the emitter of triode Q3 is grounded, and the collector of triode Q3 is connected to the processor.

[0055] In this embodiment, the frequency detection module is used to detect the working frequency of the pulses when the high-intensity pulsed light therapeutic instrument is working. The frequency detection module consists of resistor R10, resistor R11, amplifier U3, resistor R12, and triode Q3.

[0056] Among them, resistor R10 and resistor R11 form a voltage-dividing circuit. The voltage stabilizing diode U4 in the circuit is used to ensure the stability of the voltage across resistor R11, and the voltage across resistor R11 is used as the reference voltage for the non-inverting input terminal of amplifier U3. Amplifier U3 forms a comparator and compares it with the input pulse signal. When the amplitude of the pulse signal is greater than the reference voltage of the non-inverting input terminal of amplifier U3, amplifier U3 outputs a low level, and triode Q3 is cut off. At this time, the collector of triode Q3 is at a high level; when the amplitude of the pulse signal is less than the reference voltage of the non-inverting input terminal of amplifier U3, amplifier U3 outputs a high level, and triode Q3 conducts. At this time, the collector of triode Q3 is at a low level. Finally, the level signal of the collector of triode Q3 is sent to the processor, and the processor judges the frequency of the pulse signal according to the collector level of triode Q3.

[0057] Since the amplitude of the pulse signal generated by the intense pulsed light treatment instrument is relatively large, if it is directly sent to the processor, it will directly burn out the processor. Therefore, amplifier U3 also plays a role in pulse transformation, converting the high-amplitude pulse signal into a pulse signal that meets the processing requirements.

[0058] Such as Figure 4 shown, in an exemplary embodiment of the present disclosure, the current detection module includes: current sensor U6, resistor R16, resistor R15, and amplifier U5; the first end of current sensor U6 is connected to the VCC power supply, the second end of current sensor U6 is connected to the non-inverting input terminal of amplifier U5 through resistor R16, the third end of current sensor U6 is grounded, the inverting input terminal of amplifier U5 is grounded through resistor R15, and the output terminal of amplifier U5 is connected to the processor.

[0059] In this embodiment, the current detection module is used to detect the magnitude of the current of the pulse signal generated by the intense pulsed light treatment instrument. The magnitude of the current of the pulse signal is related to whether the working state of the intense pulsed light treatment instrument is normal.

[0060] In this embodiment, the current sensor U6 can be used to detect the current of the pulse signal and convert the detected current signal into a voltage signal for output. The current sensor U6 is easily affected by the environment during detection, resulting in a large amount of interference signals mixed in the output voltage signal. These interference signals will seriously affect the detection accuracy of the current. For this reason, amplifier U5 forms a differential amplifier to suppress the interference signals, and finally sends the useful signals to the processor.

[0061] Such as Figure 4As shown, in an exemplary embodiment of the present disclosure, the current detection module further includes: resistor R17, resistor R18, resistor R20, amplifier U7, and resistor R19; the first end of resistor R17 is connected to the first output end of amplifier U5, the second end of resistor R17 is connected to the inverting input end of amplifier U7, the first end of resistor R18 is connected to the second output end of amplifier U5, the first end of resistor R18 is connected to the non-inverting input end of amplifier U7, the non-inverting input end of amplifier U7 is grounded through resistor R20, the output end of amplifier U7 is connected to the inverting input end of amplifier U7 through resistor R19, and the output end of amplifier U7 is connected to the processor.

[0062] In this embodiment, the voltage signal output by the current sensor U6 is relatively weak and cannot be effectively recognized by the processor. Therefore, an amplification circuit is added between amplifier U7 and the processor in this embodiment.

[0063] The amplification circuit is composed of resistor R17, resistor R18, resistor R20, amplifier U7, and resistor R19, and is used to amplify the voltage signal output by amplifier U5, and finally send the amplified electrical signal to the processor. Among them, resistor R21 and capacitor C4 form a filtering circuit, which is used to further improve the accuracy of current detection.

[0064] As Figure 1 shown, in an exemplary embodiment of the present disclosure, it further includes: an alarm module, the alarm module is connected to the processor, and the alarm module is used to issue an alarm signal.

[0065] In this embodiment, an alarm module is additionally added. The alarm module is directly connected to the processor and is used to issue an alarm signal under specific conditions.

[0066] When the pulse amplitude detection module, the current detection module, or the frequency detection module detects that there is an abnormality in the high-frequency pulse signal, such as the pulse amplitude exceeding the preset safety threshold, the current being unstable, or the frequency deviation being too large, these detection modules will send the abnormal data to the processor. After receiving the abnormal data, the processor will perform a quick analysis and determine whether to trigger the alarm module.

[0067] If the processor determines that the abnormal situation may cause damage to the intense pulsed light therapeutic instrument or affect the treatment effect, it will send an instruction to the alarm module to trigger the alarm module to issue an alarm signal. The alarm signal can be a sound, a light signal, or other forms of alarms, so that medical staff can quickly discover and handle the abnormal situation.

[0068] After adding the alarm module, the high-frequency pulse signal detection circuit can more comprehensively ensure the safety and treatment effect of the intense pulsed light therapy instrument. Once an abnormal situation is detected, the alarm module can quickly issue an alarm to remind medical staff to deal with it in a timely manner, avoiding possible damages and adverse effects. This greatly improves the reliability and safety of the intense pulsed light therapy instrument during its later operation, providing a safer and more effective treatment experience for patients.

[0069] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them; although the present disclosure has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the present disclosure in each embodiment.
