Description

Technical Field

[0001] The present disclosure relates to a power supply calibration method, apparatus, device, medium, and program product. Background Art

[0002] Due to reasons such as environmental interference, component parameter deviation, load dynamic change, or feedback regulation error in the power supply control system, the actual output of the power supply (such as voltage, current, etc.) may not match the output expected by the user. Therefore, it is necessary to calibrate the power supply to ensure that the actual output of the power supply is consistent with the output expected by the user (such as a given value). Among them, the calibration of the power supply is particularly important for high-voltage power supplies because the output error of high-voltage power supplies often has a significant impact on the load. For example, in security inspection equipment, the high-voltage power supply is the driving core of the X-ray tube, and the stability of the output voltage directly affects the penetration ability of the X-ray and the clarity of the image. Moreover, security inspection equipment usually needs to run continuously for a long time, and the stability of the high-voltage power supply is crucial for the long-term reliability of devices such as the X-ray tube. Therefore, in security inspection equipment, in order to ensure the reliability and accuracy of the equipment, calibrating the high-voltage power supply is an essential step.

[0003] The inventors found that during the process of implementing the inventive concept of the present invention, manual intervention is usually required for power supply calibration in the prior art. For example, it is often necessary to manually read the readings of external measuring devices (such as voltmeters, ammeters), and then input them into relevant programs. This process not only has low efficiency, but also easily introduces operation errors when manually reading data. Summary of the Invention

[0027] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present disclosure. In the following detailed description, for the sake of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, obviously, one or more embodiments can also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present disclosure.

[0028] The terms used herein are merely for describing specific embodiments and are not intended to limit the present disclosure. The terms "including", "comprising", etc. used herein indicate the presence of the described features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0029] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0030] In the case of using expressions such as "at least one of A, B, and C", generally, it should be interpreted according to the meaning that those skilled in the art usually understand this expression (for example, "a system having at least one of A, B, and C" should include but not be limited to a system having only A, only B, only C, having A and B, having A and C, having B and C, and / or having A, B, and C, etc.).

[0031] Figure 1 FIG. schematically shows an application scenario diagram of a power supply calibration method according to an embodiment of the present disclosure. Among them, the power supply schematically shown in this embodiment is a high-voltage power supply. It can be understood that Figure 1 merely for illustration, the power supply in the power supply calibration method of the embodiments of the present disclosure is not limited to a high-voltage power supply.

[0032] Reference Figure 1 , since it is difficult to measure the actual output voltage and current of a high-voltage power supply on a normal device, during the voltage and current calibration process of the high-voltage power supply, generally, a voltage divider and a dummy load are used to obtain the voltage and load current of the high-voltage power supply. For example, a voltage divider can be connected to the output terminal of the high-voltage power supply 11 to reduce the high voltage proportionally to a safe range for measurement by a conventional voltmeter. The "dummy load" can be connected in series to an ammeter to measure the output current of the high-voltage power supply 11.

[0033] The high-voltage power supply 11 includes a control system. Among them, the control system can adjust the operating state of the high-voltage power supply 11 based on a set of power supply parameters (including but not limited to: voltage set value, current set value, voltage correction coefficient, current correction coefficient, etc.) set therein. Among them, the control system of the high-voltage power supply 11 will measure its output signal (voltage or current) by itself to obtain a feedback value, and then continuously adjust the operating state of the high-voltage power supply 11 by comparing the feedback value with the set value. The purpose is to make the feedback value consistent with the set value (such as the deviation is limited within a very small range) so that the high-voltage power supply 11 outputs according to the set value expected by the user. However, since the control system adjusts the operating state of the high-voltage power supply 11 based on a specific set of values of the power supply parameters, there will be a situation where if the values of the power supply parameters are unreasonable or change (such as various correction coefficients), the actual output of the power supply does not match the user's expectation. In this case, it is necessary to calibrate the power supply. For example, the value of the corresponding correction coefficient in the control system can be adjusted so that the control system can adjust the operating state of the high-voltage power supply 11 under the new set of values of the power supply parameters, and the goal is to make the actual magnitude of the output signal of the high-voltage power supply 11 consistent with the set value expected by the user.

[0034] According to an embodiment of the present disclosure, as Figure 1As shown, a detection module 421 communicating with the high-voltage power supply 11 can be used to replace the operation of manually reading voltage and current in the prior art, and on this basis, automatic current calibration can be achieved.

[0035] For example, the detection module 421 can be equipped with a communication interface that can interact with the high-voltage power supply 11, and can transmit the actual measured values of the detected voltage and current to the high-voltage power supply 11, so that the high-voltage power supply 11 can determine whether the high-voltage power supply needs to be calibrated based on the comparison between the actual measured value and the feedback value measured inside the high-voltage power supply 11.

[0036] Further, in the embodiments of the present disclosure, when the deviation between the actual measured value and the feedback value measured inside the high-voltage power supply 11 is relatively large, the corresponding correction coefficient in the control system of the high-voltage power supply 11 can be adjusted, and then the control system of the high-voltage power supply 11 is triggered to re-regulate the operating state of the high-voltage power supply 11 based on the adjusted correction coefficient, and the magnitudes of the voltage and current output by the high-voltage power supply 11 are regulated. The output of the high-voltage power supply 11 can be calibrated in multiple rounds like this until the feedback value of the voltage or current measured by the control system of the high-voltage power supply 11 itself is consistent with the actual measured value measured by the voltage divider or the ammeter connected in series with the dummy load, and the calibration is completed. The entire calibration process can be fully automated, avoiding manual participation and improving the efficiency and accuracy of calibration.

[0037] Figure 2 The flowchart of a power supply calibration method according to an embodiment of the present disclosure is schematically shown.

[0038] As Figure 2 shown, the power supply calibration method according to this embodiment may include operations S201 to S208. Taking Figure 1 the high-voltage power supply 11 in Figure 2 as an example, the power supply calibration method of

[0039] is described as follows.

[0040] Taking Figure 1 as an example, this automatic calibration instruction can be triggered when the user clicks a button such as "automatic calibration of voltage and load current" in the upper computer interface. In other scenarios, this automatic calibration instruction can also be triggered by a program. For example, when batch automatic calibration of multiple power supplies is performed, it can be controlled by a program (such as a server that batch manages the multiple power supplies), and an instruction is issued after the previous power supply calibration is completed to control the current power supply for calibration.

[0041] Among the current values of the power supply parameters, some parameters can be automatically set by the high-voltage power supply 11 when an automatic calibration instruction is received. For example, the high-voltage power supply 11 can automatically set its voltage and current set values (generally 80% of the rated voltage and current). Some other parameters can be retained after the previous calibration, such as the current correction factor and / or the voltage correction factor, etc.

[0042] Next, the calibration process of operations S202 to S206 is executed in a loop until the loop is exited when the judgment in operation S204 is negative.

[0043] In operation S202, in response to detecting that the operating state of the power supply reaches the stable operating condition, the measurement result of the target output signal (voltage or current) of the power supply by the external measurement device is collected to obtain the actual measurement value.

[0044] For example, in Figure 1 the actual voltage measurement value measured by the voltage divider can be collected through the detection module 421, and the actual current measurement value can be obtained by collecting the current signal passing through the dummy load. Then, the detection module 421 transmits the collected actual voltage measurement value and actual current measurement value to the high-voltage power supply 11 through the communication interface.

[0045] In one embodiment, the detection module 421 can have an image acquisition function, such as including a camera. For example, by restricting the positions of the camera and the voltmeter for measuring the voltage on the voltage divider (such as installing the camera directly above the screen of the voltmeter), the camera can capture the voltage reading on the voltmeter to obtain a voltage reading image. In this embodiment, the detection module 421 can also have a certain processing function. For example, after capturing the voltage reading image, the detection module 421 can also extract the voltage reading. In some embodiments, the detection module 421 can further calculate the actual voltage measurement value according to the ratio of the voltage divider and send the actual voltage measurement value to the high-voltage power supply 11. Of course, the extracted voltage reading can also be sent to the high-voltage power supply 11, and then the program in the high-voltage power supply 11 calculates the voltage data of the voltage divider to obtain the actual voltage measurement value. In this way, the external measurement device can be a conventional voltmeter or ammeter and other devices.

[0046] In some other embodiments, the detection module 421 may be a microprocessor integrated into an external measurement device. For example, the microprocessor may be integrated into a voltmeter that measures the voltage across a voltage divider. By programming and configuring the microprocessor, the microprocessor can capture a screenshot of the screen reading of the voltmeter, extract the data after the screenshot, then calculate the actual measured value of the voltage according to the multiplication factor of the voltage divider, and send the actual measured value of the voltage to the high-voltage power supply 11. Of course, the voltage data of the voltage divider read can also be sent to the high-voltage power supply 11, and then the program in the high-voltage power supply 11 calculates the voltage data of the voltage divider to obtain the actual measured value of the voltage.

[0047] In still some other embodiments, the detection module 421 may also be an external measurement device with communication functions (such as a voltmeter or ammeter capable of communication), etc. For example, the voltmeter with communication functions can be used to measure the voltage across the voltage divider and transmit the read voltage data to the high-voltage power supply 11.

[0048] It can be understood that the implementation manners of the detection module 421 exemplified above are only exemplary. In practical applications, those skilled in the art can set the specific implementation manner of the detection module 421 according to needs, as long as the goal of automatically collecting the actual measured value of the target output signal can be achieved.

[0049] In operation S203, obtain the feedback value measured by the control system of the power supply for the target output signal. Specifically, the control system of the power supply will monitor the feedback values of various output signals of the power supply in real time, and through comparison with the given value, feedback-adjust the operating state of the power supply to keep the power supply running stably and meeting the user's expectations.

[0050] In operation S204, determine whether the first deviation between the actual measured value and the feedback value is greater than a preset first deviation threshold. If so, execute operation S205; if not, execute operation S208.

[0051] In operation S205, when the first deviation is greater than the first deviation threshold, obtain the latest value of the target correction coefficient based on the actual measured value and the feedback value. When the first deviation is greater than the first deviation threshold (for example, 1‰ of the given value, only an example), it means that the feedback value of the target output signal measured by the power supply itself cannot reflect the actual situation, and it is necessary to adjust the target correction coefficient corresponding to the target output signal (such as the voltage correction coefficient corresponding to the voltage or the current correction coefficient corresponding to the current) so that the control system can re-regulate the target output signal of the power supply.

[0052] Next, in operation S206, update the value of the target correction coefficient in the power supply parameters with the latest value of the target correction coefficient.

[0053] And in operation S207, in response to the update of the power supply parameters, the control system of the power supply is re-triggered to regulate the operation of the power supply based on the current value of the power supply parameters.

[0054] Next, after operation S207, it returns to operation S202, enters a new round of calibration process, and re-determines whether the first deviation between the actual measured value and the feedback value of the target output signal is greater than the first deviation threshold after the power supply runs to a stable state again.

[0055] In operation S208, when the first deviation is not greater than the first deviation threshold, it is determined that the calibration success condition is met and the power supply calibration is completed. Among them, when the first deviation is less than or equal to the first deviation threshold, it can be determined that the feedback value of the target output signal measured by the power supply itself can reflect the actual situation, indicating that there is no need to continue calibration or the calibration is completed.

[0056] After the power supply calibration is completed, the value of the target correction coefficient in the control system is consistent with the current state of the power supply. Thus, the control system of the power supply can regulate the target output signal of the power supply according to the current value of the target correction coefficient.

[0057] Figure 3 The flowchart of the power supply calibration method according to another embodiment of the present disclosure is schematically shown. This embodiment exemplifies the calibration process of the high-voltage power supply 11.

[0058] Specifically, taking the application of the high-voltage power supply in the ray tube in the security inspection field as an example for illustration. Security inspection equipment is widely used in places such as airports, stations, and customs, and is mainly used to detect contraband, dangerous goods, etc. inside items. In these devices, the high-voltage power supply, as the driving core of the ray tube, has the following characteristics:

[0059] High voltage output: The high-voltage power supply needs to provide a DC high voltage of dozens of kilovolts to hundreds of kilovolts to excite the ray tube to generate X-rays. The stability of the output voltage directly affects the penetration ability of the rays and the clarity of the image;

[0060] High-precision requirements: Security inspection equipment needs to identify small or complex item structures through precise ray imaging technology. Therefore, the output voltage and current of the high-voltage power supply must be kept within a strict error range;

[0061] Complex load characteristics: The ray tube, as the load of the high-voltage power supply, has non-linear and dynamically changing characteristics. For example, there may be an instantaneous high current during startup. The high-voltage power supply must have a fast response ability to adapt to the dynamic load requirements of the ray tube;

[0062] Safety: Since the voltage output by the high-voltage power supply is extremely high, its design needs to fully consider the safety of operators and the equipment environment, and usually integrates various protection mechanisms, such as overvoltage protection, overcurrent protection, etc.;

[0063] Long - term stable operation: Security inspection equipment usually needs to run continuously for a long time. Therefore, the high - voltage power supply must have good heat dissipation performance and stability to ensure the long - term reliability of the equipment.

[0064] In security inspection equipment, in order to ensure the reliability and accuracy of the equipment, it is essential to calibrate the output signal of the high - voltage power supply.

[0065] As Figure 3 shown, in the power supply calibration method according to this embodiment, the only step that requires manual intervention is step S1: Click the "Automatic Calibration of Voltage and Load Current" button in the upper computer interface. The remaining steps can be automatically completed by the control program of the high - voltage power supply 11.

[0066] In step S2, after receiving the "Automatic Calibration of Voltage and Current" instruction, the high - voltage power supply 11 can automatically set its voltage and current set values (such as 80% of the rated voltage and current).

[0067] Then in step S3, the high voltage is started. Specifically, the control system of the high - voltage power supply 11 is triggered to start the operation of the high - voltage power supply 11. There is a process for the voltage and load current of the high - voltage power supply 11 to reach the set values. The control system of the high - voltage power supply 11 will monitor the feedback value of the output signal of the high - voltage power supply 11 in real time, and judge whether the output of the high - voltage power supply 11 is stable by comparing the set value of the high - voltage power supply 11 with the feedback value. For example, when the deviation between the set value and the feedback value is not greater than the second deviation threshold (for example, it can also be 1‰ of the set value or other values), and the duration for which the feedback value remains stable reaches a certain duration, it is determined that the operating state of the high - voltage power supply 11 reaches the stable operating condition.

[0068] Next, in step S4, after the output of the high - voltage power supply 11 is stable, the actual measured voltage value measured by the external measuring device can be obtained from the detection module 421 through the communication interface and the actual measured current value .

[0069] In step S5, assuming that the current voltage feedback value and current feedback value of the high - voltage power supply 11 are and , if the deviation between the actual measured voltage value and the voltage feedback value or the deviation between the actual measured current value and the current feedback value exceeds the corresponding specified range (the first deviation threshold), it is considered that calibration is required. At this time, the current voltage correction coefficient and the current correction coefficient can be obtained.

[0070] Step S6, the new voltage correction factor can be calculated through the following calculation formula and the current correction factor :

[0071]

[0072] Then, the original voltage correction factor or the current correction factor is correspondingly updated to update the original voltage correction factor or the current correction factor . In this way, since the power supply parameters change, the control system will be triggered to regulate the high-voltage power supply 11 according to the new voltage parameters.

[0073] Step S7, when the high-voltage power supply 11 runs stably again, obtain the new actual voltage measurement value or the actual current measurement value from the detection module 421 through the communication interface, and then compare it with the feedback value. If the error range still exceeds the specified range, repeat steps S5 and S6. If the error range is within the specified range, it can be considered that the calibration is completed, and the voltage correction factor or the current correction factor at this time is written into the memory of the control system of the high-voltage power supply 11. Thereafter, the control system of the high-voltage power supply 11 will control the voltage output or current output of the high-voltage power supply 11 according to the voltage correction factor or current correction factor obtained by this calibration.

[0074] The embodiments of the present disclosure can achieve one-key automatic calibration of the voltage and load current of the high-voltage power supply, and can be applied to the automatic calibration of high-voltage power supplies with multiple communication interfaces. Less manual participation, avoiding human errors, and improving the efficiency and accuracy of voltage and load current calibration.
