Description

Technical Field

[0001] This disclosure relates to the field of disinfection cabinet technology, and in particular to a control method and control circuit for a disinfection cabinet. Background Technology

[0002] Pulsed xenon lamps utilize stored electrical or chemical energy to produce a high-intensity flash within a very short time. When applied to disinfection cabinets, the high-intensity ultraviolet light from these lamps effectively destroys the DNA and RNA of bacteria and viruses, resulting in rapid and efficient disinfection.

[0003] However, in actual use, disinfection cabinets usually adopt an open-loop control method, which means that when the pulse xenon lamp or circuit malfunctions or parameters are abnormal, the system cannot detect it automatically and there are no corresponding handling measures. It is necessary to rely on manual discovery and intervention, which affects the sterilization effect and efficiency of the disinfection cabinet. Summary of the Invention

[0004] To address at least one of the aforementioned technical problems, this disclosure provides a control method and control circuit for a disinfection cabinet.

[0005] According to a first aspect of the present disclosure, a method for controlling a disinfection cabinet is provided. The disinfection cabinet includes a discharge capacitor and a pulsed xenon lamp. The discharge capacitor is used for charging and storing energy and discharging it to the pulsed xenon lamp. The method includes:

[0006] The voltage value of the discharge capacitor is obtained during the first disinfection period; the first disinfection period starts at the moment when the disinfection cabinet starts the disinfection program, and the first disinfection period has a first preset duration; the first disinfection period includes a first preset number of disinfection cycles, and the disinfection cycle includes a charging stage and a discharging stage, the charging stage is the stage in which the discharge capacitor is charged, and the discharging stage is the stage in which the discharge capacitor discharges to the pulse xenon lamp;

[0007] Based on the voltage values ​​corresponding to each discharge stage during the first disinfection period, the working status of the disinfection cabinet under the first detection index and the second detection index is determined.

[0008] When the disinfection cabinet is in an abnormal state under either the first detection indicator or the second detection indicator, the first disinfection period is extended to a second disinfection period.

[0009] In one embodiment, determining the operating status of the disinfection cabinet under the first detection index and the second detection index based on the voltage values ​​corresponding to each discharge stage of the first disinfection period includes:

[0011] The time period in which the voltage value corresponding to each discharge stage of the detection phase meets a first preset condition is obtained; the first preset condition is that the voltage value is greater than or equal to a first preset value and less than or equal to a second preset value.

[0012] Determine the duration of each time period that meets the first preset condition;

[0013] The duration of the time period that meets the first preset condition is used as the first detection indicator to determine the working status of the disinfection cabinet under the first detection indicator.

[0014] In one embodiment, determining the operating status of the disinfection cabinet under the first detection index and the second detection index based on the voltage values ​​corresponding to each discharge stage of the first disinfection period includes:

[0015] If the voltage value corresponding to the discharge phase remains unchanged, the state of the disinfection cycle corresponding to the discharge phase is determined to be a flashover state.

[0016] Determine the number of disinfection cycles that meet the flashover state within the first disinfection period;

[0017] The number of disinfection cycles that meet the leakage state within the first disinfection period is used as the second detection index to determine the working status of the disinfection cabinet under the second detection index.

[0018] In one embodiment, determining the working status of the disinfection cabinet under the first detection indicator includes:

[0020] If the value of the first detection index is greater than or equal to the second threshold, the state of the disinfection cycle corresponding to the time period that meets the first preset condition is determined as the second disinfection state.

[0021] The ratio of the number of disinfection cycles satisfying the first disinfection state to the second preset number is determined as a first ratio, and the ratio of the number of disinfection cycles satisfying the second disinfection state to the second preset number is determined as a second ratio.

[0022] If the second ratio is greater than or equal to the third threshold, a test result is obtained that indicates the disinfection cabinet is in a first fault state under the first test index;

[0023] If the second ratio is less than the third threshold, and the sum of the first ratio and the second ratio is greater than or equal to the fourth threshold, a detection result is obtained that characterizes the disinfection cabinet as being in a first abnormal state under the first detection index, and the first abnormal state belongs to the abnormal state.

[0024] If the sum of the first ratio and the second ratio is less than the fourth threshold, and the second ratio is less than the third threshold, a test result is obtained that indicates the disinfection cabinet is in a first normal state under the first test index.

[0025] In one embodiment, determining the working status of the disinfection cabinet under the second detection indicator includes:

[0026] When the value of the second detection index is less than the fifth threshold, a detection result is obtained that indicates that the disinfection cabinet is in a second normal state under the second detection index.

[0027] When the value of the second detection index is greater than or equal to the fifth threshold and less than or equal to the sixth threshold, a detection result is obtained that characterizes the disinfection cabinet as being in a second abnormal state under the second detection index, and the second abnormal state belongs to the abnormal state.

[0028] If the value of the second detection index is greater than the sixth threshold, a detection result is obtained that indicates that the disinfection cabinet is in a second fault state under the second detection index.

[0029] In one embodiment, extending the first disinfection period to a second disinfection period when the disinfection cabinet is in an abnormal state under either the first detection indicator or the second detection indicator includes:

[0030] If the voltage value corresponding to each discharge stage of the disinfection process meets the second preset condition, the second preset time required for the disinfection cabinet to achieve the preset disinfection effect is determined; the second preset condition is that the time taken for the voltage to decrease from the second preset value to the first preset value is the second threshold.

[0031] When the disinfection cabinet is in the first abnormal state under the first detection indicator and in the second normal state under the second detection indicator, the first disinfection period is extended to the second disinfection period, and the second disinfection period has the second preset duration.

[0032] In one embodiment, extending the first disinfection period to a second disinfection period when the disinfection cabinet is in an abnormal state under either the first detection indicator or the second detection indicator includes:

[0033] When the disinfection cabinet is in the second abnormal state under the second detection index and in the first normal state under the first detection index, the first disinfection period is extended to the second disinfection period; the number of disinfection cycles that do not meet the leakage state within the second disinfection period is the first preset number.

[0034] In one embodiment, extending the first disinfection period to a second disinfection period when the disinfection cabinet is in an abnormal state under either the first detection indicator or the second detection indicator includes:

[0035] If the voltage value corresponding to each discharge stage of the disinfection process meets the second preset condition, determine the second preset time required for the disinfection cabinet to achieve the preset disinfection effect and the number of disinfection cycles corresponding to the second preset time; the second preset condition is that the time taken to decrease from the second preset value to the first preset value is the second threshold.

[0036] When the disinfection cabinet is in the first abnormal state under the first detection indicator and in the second abnormal state under the second detection indicator, the first disinfection period is extended to the second disinfection period. The number of disinfection cycles that do not meet the leakage state within the second disinfection period is the number of disinfection cycles corresponding to the second preset duration.

[0037] According to a second aspect of the present disclosure, a control circuit for a disinfection cabinet is provided, the control circuit being used to implement the control method described in any one of the first aspects above, the control circuit comprising:

[0038] A triggering circuit, which is electrically connected to the pulsed xenon lamp, is used to trigger the pulsed xenon lamp to perform flashing operation;

[0040] An energy storage circuit, the energy storage circuit including a discharge capacitor, the discharge capacitor being used to charge and store energy and discharge it to the pulsed xenon lamp;

[0041] A voltage sampling circuit is connected to both ends of the discharge capacitor to detect the voltage value of the discharge capacitor, so that the controller can send the control command based on the voltage value.

[0042] In one embodiment, the voltage sampling circuit is connected to the controller; the voltage sampling circuit includes a resistor divider network and a comparator with feedback.

[0043] The resistor divider network is used to divide the voltage of the discharge capacitor, and the comparator with feedback is used to output the voltage value of the discharge capacitor after being reduced by a preset factor.

[0044] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure.

[0045] Implementing this disclosure will have the following beneficial effects:

[0046] By monitoring the voltage value of the discharge capacitor at each discharge stage, the working status of the disinfection cabinet can be judged in real time during the disinfection process. When the disinfection cabinet is in an abnormal state, the disinfection time is automatically extended to compensate for the insufficient disinfection effect caused by the abnormal state, thereby ensuring that the overall disinfection effect meets expectations. Through automated detection and adjustment, users do not need to frequently intervene in the disinfection process, reducing the user's operational burden and improving the user experience.

[0062] A disinfection cabinet includes a discharge capacitor and a pulsed xenon lamp. The discharge capacitor is used to charge and store energy and then discharge it to the pulsed xenon lamp. The pulsed xenon lamp uses the high-energy pulsed current released by the capacitor to generate a strong ultraviolet light beam, thereby effectively sterilizing and disinfecting the items inside the cabinet.

[0063] Figure 1 This diagram illustrates a flow chart of a control method for a disinfection cabinet according to an embodiment of the present disclosure, as shown below. Figure 1 The above methods include:

[0064] S101. Obtain the voltage value of the discharge capacitor during the first disinfection period.

[0065] In one embodiment, the first disinfection period begins when the disinfection cabinet starts its disinfection program, and has a first preset duration. The first disinfection period includes a first preset number of disinfection cycles, each including a charging phase and a discharging phase. The charging phase involves charging the discharge capacitor, and the discharging phase involves the discharge capacitor discharging to the pulsed xenon lamp. The disinfection program is a series of pre-set and automatically executed operations within the disinfection cabinet. By controlling the charging and discharging of the discharge capacitor at a fixed frequency, the pulsed xenon lamp generates the ultraviolet light beam required for disinfection, thereby achieving the sterilization effect. The disinfection program begins when the disinfection cabinet starts and continues for the first preset duration. This disclosure does not limit the first preset duration; it is sufficient to ensure that the preset disinfection effect is achieved within that duration.

[0066] S102. Based on the voltage values ​​corresponding to each discharge stage during the first disinfection period, determine the working status of the disinfection cabinet under the first and second detection indicators.

[0067] Based on the discharge characteristics of a pulsed xenon lamp, when the lamp is on, it is equivalent to a very small resistor R1, while the internal resistance of the discharge capacitor is R2. The entire circuit is equivalent to a resistor-capacitor (RC) circuit. The discharge capacitor is the component that stores charge, while the resistor restricts the flow of current. Specifically, the larger the resistance, the greater the restriction on current flow, resulting in a slower voltage decay of the discharge capacitor; conversely, the smaller the resistance, the smoother the current flow, and the faster the voltage of the discharge capacitor drops. During the charging phase, the discharge capacitor acquires charge from the power source, and the voltage gradually increases; during the discharging phase, the discharge capacitor releases charge through the resistor, and the voltage gradually decreases. During the discharge process, the voltage of the discharge capacitor decays exponentially with time, and its voltage change over time can be expressed by the following formula:

[0068]

[0069] Where V(t) is the voltage at the discharge moment, V0 is the initial voltage, t is the time, R is the resistance value, and C is the capacitance value.

[0070] By monitoring the voltage value during the discharge phase, it is possible to infer whether the parameters of resistance and capacitance are within the expected range. For example, if the voltage decay rate is too slow, it may mean that the resistance in the circuit is too high, indicating that there may be an abnormality in the working status of the disinfection cabinet. Therefore, the operation of the disinfection cabinet can be evaluated in real time by monitoring the voltage value during the discharge phase to ensure the effectiveness and stability of the disinfection process.

[0071] In one embodiment, such as Figure 2 , Figure 2 This diagram illustrates a flowchart of determining a first detection index according to an embodiment of the present disclosure, including:

[0072] S201. Determine a second preset number of consecutive disinfection cycles within the first disinfection period as the testing phase.

[0073] This disclosure does not limit the second preset number; the specific setting can be flexibly adjusted according to the requirements of detection accuracy. By using a second preset number of consecutive disinfection cycles during the first disinfection period as the detection stage, accurate and stable monitoring of the disinfection cabinet's working status can be ensured. Evaluation over multiple consecutive cycles can eliminate accidental errors or fluctuations, ensuring the reliability of the detection results.

[0074] S202. Obtain the time period in which the voltage value corresponding to each discharge stage of the detection stage meets the first preset condition.

[0075] In one embodiment, the first preset condition is a voltage value greater than or equal to a first preset value and less than or equal to a second preset value. This disclosure does not limit the first and second preset values. In one embodiment, the first preset value is set as the minimum voltage required to achieve a sterilization effect, and the second preset value is set as the voltage value when the discharge capacitor has finished charging. The time period corresponding to a voltage value greater than or equal to the first preset value and less than or equal to the second preset value represents an effective working range for the disinfection cabinet during the discharge phase.

[0076] S203. Determine the duration of each time period that meets the first preset condition.

[0077] S204. The duration of the time period that meets the first preset condition is used as the first detection indicator to determine the working status of the disinfection cabinet under the first detection indicator.

[0078] The sterilization function of pulsed xenon lamps relies on the instantaneous high-energy release of the discharge capacitor. The capacitor discharges rapidly, creating a high-intensity light pulse that ensures effective sterilization. If the voltage value of the disinfection cabinet remains within the first preset range for an extended period during the discharge phase, it indicates an abnormality in the discharge process. For example, the discharge capacitor may discharge too slowly, or the energy may not be released effectively within the predetermined time, resulting in dispersed or insufficient pulse energy and affecting the disinfection effect. The duration of the period meeting the first preset condition is used as the primary detection indicator to accurately assess whether the disinfection effect of each disinfection cycle is within the expected range, thereby achieving real-time control of the entire disinfection process.

[0079] This disclosure does not limit the method for determining the working state of a disinfection cabinet under the first detection index. In one embodiment, such as... Figure 4 , Figure 4 A flowchart illustrating the determination of the operating status of a disinfection cabinet under a first detection indicator according to an embodiment of the present disclosure is shown, including:

[0080] S401. If the value of the first detection index is greater than or equal to the first threshold and less than the second threshold, the state of the disinfection cycle corresponding to the time period that meets the first preset condition is determined as the first disinfection state.

[0081] The first disinfection state refers to a state where partial disinfection effect is achieved, but the standard requirements are not met. This disclosure does not limit the specific values ​​of the first threshold and the second threshold. As long as the value of the first detection index is between the first threshold and the second threshold, the disinfection cycle of the disinfection cabinet is maintained in a state where partial disinfection effect is achieved, but the standard requirements are not met.

[0082] S402. If the value of the first detection index is greater than or equal to the second threshold, the state of the disinfection cycle corresponding to the time period that meets the first preset condition is determined as the second disinfection state.

[0083] The second disinfection state refers to a state in which no disinfection effect is achieved. This disclosure does not limit the specific value of the second threshold; as long as the value of the first detection index is greater than or equal to the second threshold, the disinfection cycle of the disinfection cabinet is guaranteed to be in a state in which no disinfection effect is achieved.

[0084] S403. Determine the ratio of the number of disinfection cycles that meet the first disinfection state to the second preset number as the first ratio, and determine the ratio of the number of disinfection cycles that meet the second disinfection state to the second preset number as the second ratio.

[0085] S404. If the second ratio is greater than or equal to the third threshold, the test result representing the disinfection cabinet being in the first fault state under the first test index is obtained.

[0086] This disclosure does not limit the third threshold. In one embodiment, the third threshold is 10%. When the second ratio is greater than or equal to 10%, it indicates that the overall disinfection effect is seriously insufficient, and the disinfection cabinet is in a first fault state under the first detection index. When the disinfection cabinet is detected to be in a first fault state under the first detection index, the operation of the disinfection cabinet is immediately stopped, and a fault prompt is issued to the user.

[0087] S405. If the second ratio is less than the third threshold, and the sum of the first ratio and the second ratio is greater than or equal to the fourth threshold, the test result indicating that the disinfection cabinet is in the first abnormal state under the first test index is obtained.

[0088] This disclosure does not limit the fourth threshold. In one embodiment, the fourth threshold is 20%. When the second ratio is less than 10% and the sum of the first ratio and the second ratio is greater than or equal to 20%, it indicates that the overall disinfection effect is slightly insufficient and the disinfection cabinet is in a first abnormal state under the first detection index. The first abnormal state is an abnormal state.

[0089] S406. If the sum of the first ratio and the second ratio is less than the fourth threshold, and the second ratio is less than the third threshold, the test result indicating that the disinfection cabinet is in the first normal state under the first test index is obtained.

[0090] In one embodiment, when the sum of the first ratio and the second ratio is less than 20% and the second ratio is less than 10%, it indicates that the overall disinfection effect meets the standard requirements and the disinfection cabinet is in the first normal state under the first test index.

[0091] By classifying the duration of time periods that meet the first preset conditions, the actual disinfection effect of the disinfection cycle can be monitored more accurately; by calculating the first ratio and the second ratio, the disinfection effect of the disinfection cabinet during the testing phase can be quantified, thereby achieving real-time control of the entire disinfection process.

[0092] In one embodiment, such as Figure 3 , Figure 3 This diagram illustrates a flowchart of determining a second detection index according to an embodiment of the present disclosure, including:

[0093] S301. If the voltage value corresponding to the discharge phase remains unchanged, determine the state of the disinfection cycle corresponding to the discharge phase as the flashover state.

[0094] Under normal operating conditions, the discharge capacitor should have a sufficiently high voltage when fully charged to trigger the pulsed xenon lamp. As the pulsed xenon lamp is used for longer periods, the lamp tube gradually ages, and the state of the internal electrodes may change, causing the trigger voltage—the minimum voltage required to ignite the lamp—to rise. Because the voltage fails to reach the lamp's trigger voltage, the voltage value of the discharge capacitor remains unchanged during the discharge phase, resulting in a flashover state during the disinfection cycle.

[0095] S302. Determine the number of disinfection cycles that meet the flashover condition within the first disinfection period.

[0096] S303. The number of disinfection cycles that meet the leakage state within the first disinfection period is used as the second detection indicator to determine the working status of the disinfection cabinet under the second detection indicator.

[0097] During the disinfection process, the flashing state of the pulsed xenon lamp in each disinfection cycle directly affects the disinfection effect. Each flash of the pulsed xenon lamp releases ultraviolet light to kill bacteria or viruses. If the pulsed xenon lamp fails to trigger, meaning the disinfection cycle is in a flash-missing state, it indicates that the disinfection cycle has not achieved the expected disinfection effect. Therefore, the occurrence of flash-missing states is closely related to the actual disinfection performance of the disinfection cabinet; the more disinfection cycles that meet the flash-missing state, the worse the disinfection effect. By counting the number of disinfection cycles that meet the flash-missing state during the first disinfection period, the number of disinfection cycles that fail to achieve the preset disinfection effect can be accurately identified, thereby more accurately assessing the overall disinfection effect of the disinfection cabinet and ensuring the reliability and effectiveness of disinfection.

[0098] This disclosure does not limit the method for determining the working status of the disinfection cabinet under the second testing indicator. In one embodiment, such as Figure 5 , Figure 5 A flowchart illustrating the determination of the operating status of a disinfection cabinet under a second detection indicator according to an embodiment of the present disclosure is shown, including:

[0099] S501. When the value of the second detection index is less than the fifth threshold, the detection result indicating that the disinfection cabinet is in the second normal state under the second detection index is obtained.

[0100] This disclosure does not limit the specific value of the fifth threshold. When the value of the second detection index is less than the fifth threshold, it is sufficient to ensure that the disinfection cabinet meets the preset disinfection effect after completing the disinfection program.

[0101] S502. If the value of the second detection index is greater than or equal to the fifth threshold and less than or equal to the sixth threshold, a detection result indicating that the disinfection cabinet is in a second abnormal state under the second detection index is obtained. The second abnormal state is an abnormal state.

[0102] S503. If the value of the second detection index is greater than the sixth threshold, a detection result indicating that the disinfection cabinet is in a second fault state under the second detection index is obtained. When the disinfection cabinet is detected to be in a second fault state under the second detection index, the operation of the disinfection cabinet is immediately stopped, and a fault prompt is issued to the user.

[0103] This disclosure does not limit the specific value of the sixth threshold; the specific setting can be flexibly adjusted according to the requirements of fault detection.

[0104] By monitoring and classifying the second detection indicator, the overall disinfection effect of the disinfection cabinet can be evaluated more accurately, abnormal disinfection problems of the disinfection cabinet can be identified in a timely manner, and the reliability and safety of the disinfection cabinet can be improved.

[0105] S103. When the disinfection cabinet is in an abnormal state under either the first or second detection indicator, the first disinfection period shall be extended to the second disinfection period.

[0106] In one embodiment, when the disinfection cabinet is in a first abnormal state under the first detection indicator and in a second normal state under the second detection indicator, the first disinfection period is extended to a second disinfection period, and the second disinfection period has a second preset duration.

[0107] This disclosure does not limit the second preset duration. In one embodiment, the second preset duration can be determined as follows: When the voltage values ​​corresponding to each discharge stage of the disinfection process meet the second preset condition, the second preset duration required for the disinfection cabinet to achieve the preset disinfection effect is determined. The second preset condition is the time taken for the voltage to decrease from the second preset value to the first preset value, which is a second threshold. By setting the duration for each discharge stage to have a disinfection effect as the second threshold, the duration required for the entire disinfection process to meet the preset disinfection effect under this condition is measured. The second threshold is the maximum value of the first detection index when the disinfection cycle has a disinfection effect. By extending the first disinfection period to the second disinfection period, the insufficient disinfection effect caused by the first abnormal state can be compensated, ensuring that the disinfection cabinet meets the preset disinfection effect. By determining the second preset duration, only the necessary disinfection time is extended, avoiding unnecessary energy consumption and improving resource utilization efficiency.

[0108] In one embodiment, when the disinfection cabinet is in a second abnormal state under the second detection indicator and in a first normal state under the first detection indicator, the first disinfection period is extended to a second disinfection period. The number of disinfection cycles that do not meet the "flickering" condition during the second disinfection period is a first preset number. By ensuring that the number of disinfection cycles that are not in a "flickering" state reaches the first preset number during the second disinfection period, the influence of the "flickering" state is eliminated, the number of disinfection cycles with disinfection effect is increased, and the preset disinfection effect is ultimately achieved.

[0109] In one embodiment, when the disinfection cabinet is in a first abnormal state under the first detection indicator and in a second abnormal state under the second detection indicator, the first disinfection period is extended to a second disinfection period, and the number of disinfection cycles that do not meet the leakage state within the second disinfection period is the number of disinfection cycles corresponding to the second preset duration.

[0110] If the voltage values ​​corresponding to each discharge stage of the disinfection process meet the second preset condition, determine the second preset time required for the disinfection cabinet to achieve the preset disinfection effect and the number of disinfection cycles corresponding to the second preset time; the second preset condition is that the time taken to decrease from the second preset value to the first preset value is the second threshold. Based on the fixed duration of each disinfection cycle, the number of disinfection cycles included in the disinfection process within the second preset time can be calculated.

[0111] By ensuring that the number of disinfection cycles without leakage during the second disinfection period reaches the number of disinfection cycles corresponding to the second preset duration, the insufficient disinfection effect caused by the first and second abnormal states can be effectively compensated, ensuring that the disinfection process of the disinfection cabinet meets the preset disinfection effect.

[0112] When the disinfection cabinet is in an abnormal state, it automatically extends the disinfection time to compensate for insufficient disinfection effect caused by the abnormal state, thereby ensuring that the overall disinfection effect meets expectations. By automatically detecting and adjusting the disinfection time, users do not need to frequently intervene in the disinfection process, reducing the user's operational burden and improving the user experience.

[0113] This disclosure also provides a control circuit for a disinfection cabinet, which is used to implement the above-described control method. For example... Figure 6 , Figure 6This diagram illustrates a module schematic of a control circuit for a disinfection cabinet according to an embodiment of the present disclosure. The control circuit includes: a trigger circuit electrically connected to a pulsed xenon lamp for triggering the lamp to flash; a controller electrically connected to the trigger circuit for sending control commands to the trigger circuit, the control commands instructing the trigger circuit to trigger the pulsed xenon lamp to flash; an energy storage circuit including a discharge capacitor for charging and discharging energy to the pulsed xenon lamp; a power supply for charging and storing energy; and a voltage sampling circuit connected to the controller and connected to both ends of the discharge capacitor for detecting the voltage value of the discharge capacitor, enabling the controller to send control commands based on the voltage value.

[0114] This disclosure does not limit the voltage sampling circuit; in one embodiment, such as Figure 7 , Figure 7 A circuit diagram of a voltage sampling circuit according to an embodiment of the present disclosure is shown.

[0115] The voltage sampling circuit includes a resistor divider network 10, a diode 20, and a comparator with feedback. The comparator with feedback consists of a comparator 30 and a feedback loop 40. The resistor divider network 10 divides the voltage of the discharge capacitor; a capacitor is connected between the resistor and ground to filter out noise in the voltage signal, ensuring a stable voltage signal reaching the comparator 30. The diode 20 provides reverse voltage protection to prevent the voltage signal from exceeding the safe range. The resistor divider network 10 allows the voltage to adapt to the measurement range of subsequent circuits, ensuring the safety and stability of the measurement; the comparator with feedback can quickly respond to voltage changes and output a voltage value reduced by a preset factor in real time for direct reading by the controller.
