Description

Technical Field

[0001] The present invention relates to the technical field of high-frequency power supply signal collection, and specifically to a method and apparatus for collecting high-frequency power supply signals.

Background Art

[0002] Regarding high-frequency power supplies, current collection boards collect voltage and current signals through continuous sampling. It is an inevitable phenomenon that the voltage and current signals collected in the PULSE mode and when the switch is switched become ramp signals. On the other hand, since the voltage and current values read in the ramp stage are inaccurate, the power values and resistance values calculated in the next step are also inaccurate. High-frequency power supplies generate ramps in the voltage and current signals collected in the PULSE mode and when the switch is switched, and since the voltage and current values read in the ramp stage are inaccurate, the power values and resistance values calculated in the next step are also inaccurate. In the prior art, it is impossible to avoid the ramps generated when the switch of the high-frequency power supply is switched and in the PULSE mode.

[0004] In order to solve the above technical problems, the embodiments disclosed by the present invention provide at least a method and apparatus for collecting high-frequency power supply signals.

[0005] In a first aspect, the embodiments disclosed by the present invention are The steps include determining the rising edge and falling edge segments within the current pulse period based on the power change amount of consecutive sampling points and a predetermined judgment threshold, The steps include determining abnormal data bits corresponding to the rising edge interval and the falling edge interval in the sampling sequence, The present invention provides a method for acquiring a high-frequency power supply signal, which includes the steps of setting the abnormal data bit to 0, a null signal value, or a low signal level value, or skipping the output of the abnormal data bit when outputting sampled data.

[0006] The step of selectively determining rising edge and falling edge segments within the current pulse period based on the power change amounts of consecutive sampling points and a predetermined determination threshold includes: continuously collecting high-frequency power signals from at least three sampling points in a time series; determining the power of each sampling point based on the high-frequency power signals; sequentially subtracting the acquired power values ​​of each sampling point to obtain at least two power change amounts from any two adjacent sampling points; and determining rising edge and falling edge segments within the current pulse period based on the power change amounts and the predetermined determination threshold.

[0007] The step of selectively determining rising edge segments and falling edge segments within the current pulse period based on the power change and the predetermined determination threshold includes the steps of determining the rule for the change in the power change, determining that the current sampling point is within a rising edge segment or a falling edge segment if at least one of the power change amounts is above or below the predetermined determination threshold, and determining that the current sampling point is not within a rising edge segment or a falling edge segment otherwise.

[0008] The step of selectively determining that the current sampling point is not within a rising edge interval or a falling edge interval includes determining that the signal at the current sampling point is in a fluctuating state if two consecutive power change amounts have opposite directions of change and both are below a predetermined determination threshold.

[0009] Selectively, the predetermined determination threshold is Δth, where 0 < Δth, and at least two power changes of any two adjacent sampling points include Δ1 and Δ2, and at least one of the power changes being above or below the predetermined determination threshold includes at least one of the equations +Δth ≤ |Δ1| and +Δth ≤ |Δ2| being true.

[0010] Selectively, the condition that two consecutive power changes have opposite directions of change and are both below the predetermined threshold includes the conditions that 0 ≤ Δ1 < Δth and -Δth < Δ2 ≤ 0 are simultaneously met, or that -Δth < Δ1 ≤ 0 and 0 ≤ Δ2 < Δth are simultaneously met.

[0011] Selectively, the condition that at least one of the equations +Δth≦|Δ1| and +Δth≦|Δ2| holds includes, when both equations +Δth≦|Δ1| and +Δth≦|Δ2| hold simultaneously, the equations +Δth≦Δ1 and +Δth≦Δ2 hold simultaneously when the power change is continuously increasing, and the equations Δ1≦-Δth and Δ2≦-Δth hold simultaneously when the power change is continuously decreasing.

[0012] Selectively, the sampling array reads and outputs sampled data sequentially outside of the rising edge interval and the falling edge interval.

[0017] By detecting the slope of the feedback signal and determining the ramp interval, it is determined whether the collected data is accurate. When it is determined to be accurate, the collected data is retained; otherwise, the abnormal data bit is set to 0, a null signal value or a low-level value of the signal, or the abnormal data is skipped when the data is output. Thereby, it is possible to determine whether the data collected based on the slope of the collected signal is accurate, further correct the inaccurate ramp signal collected in the PULSE mode when the high-frequency power supply switch is switched, and finally make the calculated power value and resistance value accurate.

Embodiments for Carrying out the Invention

[0021] Here, exemplary embodiments are described in detail and their examples are shown in the drawings. In the following, when referring to the drawings for description, unless otherwise specified, the same numbers in different drawings represent the same elements or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments that conform to the present invention. On the contrary, they are merely examples of devices and methods that conform to some aspects of the present invention detailed in the appended claims.

[0022] Example 1 As shown in FIG. 1 which is a flowchart of the high-frequency power signal collection method provided by the embodiments disclosed by the present invention, the method includes: S11: Determining the rising edge section and the falling edge section within the current pulse period based on the power change amount of continuous sampling points and a predetermined determination threshold value; S12: Determining abnormal data bits corresponding to the rising edge section and the falling edge section in the sampling array; S13: Setting the abnormal data bits to 0, a null signal value, or a low-level value of the signal, or skipping the output of the data of the abnormal data bits when outputting the sampling data; S14: Outside the rising edge section and the falling edge section, the sampling array reads the sampling data and outputs it sequentially.

[0023] The technical solution provided by this embodiment involves detecting the slope of the feedback signal to determine the ramp section, determining whether the collected data is accurate, retaining the collected data if it is accurate, and otherwise setting the abnormal data bits to 0, a null signal value, or a low signal level, or skipping the abnormal data when outputting the data. This allows for determining whether the collected data is accurate based on the slope of the collected signal, calibrating inaccurate ramp signals collected during high-frequency power supply switching and in PULSE mode, and ultimately ensuring the accuracy of the calculated power and resistance values.

[0024] Example 2 As shown in Figure 2, which is a flowchart of another method for acquiring high-frequency power supply signals provided by embodiments disclosed in the present invention, and referring to Figure 3, the method is: Step S21 determines the rising edge section and falling edge section within the current pulse period based on the power change amount of consecutive sampling points and a predetermined judgment threshold, S22 determines the abnormal data bits corresponding to the rising edge intervals and falling edge intervals in the sampling sequence, S23 sets abnormal data bits to 0, a null signal value, or a low signal level value, or skips outputting data for abnormal data bits when outputting sampled data. This includes S24, in which the sampling array reads the sampled data and outputs it sequentially outside of the rising edge interval and the falling edge interval.

[0025] In some of the selectable embodiments, as shown in the dashed area of ​​Figure 2, S21 is: Step S211 involves continuously acquiring high-frequency power supply signals from at least three sampling points in a time series, S212 determines the power value of each sampling point based on the high-frequency power supply signal, S213 sequentially subtracts the power values ​​of each acquired sampling point and obtains at least two power change amounts for any two adjacent sampling points. S214 includes determining the rising edge section and falling edge section within the current pulse period based on the power change and a predetermined determination threshold.

[0026] In some selectable embodiments, S214 is The steps include determining the rules governing the change in power output, The steps include determining that the current sampling point is within a rising edge interval or a falling edge interval if at least one of the power change amounts exceeds or falls below a predetermined threshold, The step of determining, otherwise, that the current sampling point is not within a rising edge interval or a falling edge interval, specifically, in some selectable embodiments, that the signal at the current sampling point is in a fluctuating state if two consecutive power changes have opposite directions of change and both are below a predetermined threshold.

[0027] In several selectable embodiments, a predetermined threshold is Δth, where 0 < Δth, and at least two power changes of any two adjacent sampling points include Δ1 and Δ2, and in the above process, the power change being continuously above or below the predetermined threshold includes the simultaneous holding of equations +Δth ≤ |Δ1| and +Δth ≤ |Δ2|.

[0028] It should be explained that if 0≦Δ1<+Δth and +Δth≦Δ2 are simultaneously true, or if +Δth≦Δ1 and 0≦Δ2<+Δth are simultaneously true, the current sampling point signal may be in a fluctuating state, may be at the beginning of a rising edge interval, the data is inaccurate, and all data collected in such cases should be discarded. If Δ1≦-Δth and 0≦Δ2<+Δth are simultaneously true, or if 0≦Δ1<+Δth and Δ2≦-Δth are simultaneously true, the current sampling point signal may be in a fluctuating state, may be at the beginning of a falling edge interval, the data is inaccurate, and all data collected in such cases should be discarded.

[0029] In some selectable embodiments, two consecutive power changes having opposite directions of change and both being below a predetermined threshold means that the equations 0 ≤ Δ1 < Δth and -Δth < Δ2 ≤ 0 are simultaneously true, or that the equations -Δth < Δ1 ≤ 0 and 0 ≤ Δ2 < Δth are simultaneously true.

[0030] In some selectable embodiments, the condition that at least one of the above equations +Δth≦|Δ1| and +Δth≦|Δ2| holds is that when equations +Δth≦|Δ1| and +Δth≦|Δ2| hold simultaneously, When the rate of change in power increases continuously, the equations +Δth≦Δ1 and +Δth≦Δ2 hold simultaneously. This includes the condition that when the rate of change in power decreases continuously, equations Δ1 ≤ -Δth and Δ2 ≤ -Δth hold simultaneously.

[0031] In several selectable embodiments, as shown in Figure 4, the high-frequency power supply generates ramps during switch switching and in PULSE mode. Of these, the low-power data collected from the starting point to point A is accurate, the ramp from point A to point B is rising and the data collected during this period is inaccurate, the high-power data collected from point B to point C is accurate, the ramp from point C to point D is falling and the data collected during this period is inaccurate, and the low-power data collected from point D to point E is accurate. As shown in Figure 4, the time series of the three consecutive power values ​​P1, P2, and P3 collected shows that P1 is the latest data collected, followed by P2, and P3 is the earliest data collected.

[0032] Refer to Figure 3, which is a flowchart for determining whether the collected data of this invention is accurate. The collected power values ​​are sequentially subtracted to obtain the change amounts Δ1=P1-P2 and Δ2=P2-P3, and Δth is greater than 0, which is the threshold for determining whether the collected data is accurate. The collected data is accurate if the absolute values ​​of both change amounts are less than the determination threshold Δth. In this case, the corresponding collected data is retained; otherwise, the abnormal data bit is set to 0, a null signal value, or a low signal level value, or the output of the abnormal data bit is skipped when outputting the sampled data. That is, if the absolute value of at least one of Δ1 and Δ2 is greater than or equal to +Δth, the data is inaccurate, and all data collected in such cases is discarded.

[0033] As shown in Figure 5, the ramp in the feedback signal is removed after calibration using the tilt determination method proposed by the present invention.

[0034] It should be explained that the above method for acquiring high-frequency power supply signals can be used to solve the problem of inaccurate acquired signals within the ramp section, particularly during switch switching and in PULSE mode, within one pulse period.

[0035] To facilitate understanding for the reader, the process of realizing the high-frequency power supply signal acquisition described above will be explained below with reference to Figures 4 and 5.

[0036] Example 1: Determination and processing of situations related to rising edges

[0037] Within one pulse period, the power values ​​at the acquisition points are calculated sequentially. When different power values ​​change, the determination result and processing method for the rising edge are as follows, with Δth = 1.5W.

[0038] For situation 1, there is one change in which the absolute value is greater than or equal to a predetermined threshold Δth.

[0039] 1-1. For example, the power values ​​of three consecutively acquired sampling points are P1=11W, P2=9W, and P3=8W, respectively. The power changes obtained by sequentially subtracting the acquired power values ​​are Δ1=P1-P2=2>+Δth and Δ2=P2-P3=1W<+Δth, respectively. Here, if there is one change where Δ1>+Δth, that is, the absolute value ≥ a predetermined judgment threshold Δth, the collected data is inaccurate. In this case, the data from sampling points P1, P2, P3 or P1, P2 are discarded, that is, the data from sampling points P1, P2, P3 or P1, P2 are set to 0, a null signal value, or a low signal level. Furthermore, if the power change Δ1>+Δth occurs for the first time within the current pulse period, and the power change Δ2<+Δth, it is determined that P2 is the starting point of the rising edge within the current pulse period.

[0040] 1-2. For example, the power values ​​of three consecutively acquired sampling points are P1=20W, P2=20W, and P3=17W, respectively. The power changes obtained by sequentially subtracting the acquired power values ​​are Δ1=P1-P2=0<+Δth and Δ2=P2-P3=3W>+Δth, respectively. Here, if there is one change where Δ2>+Δth, that is, the absolute value ≥ a predetermined judgment threshold Δth, the collected data is inaccurate. In this case, the data for sampling points P1, P2, P3 or P2, P3 is discarded, that is, the data for sampling points P1, P2, P3 or P2, P3 is set to 0, a null signal value, or a low signal level. Furthermore, if the power change Δ1<+Δth occurs for the first time within the current pulse period and the power change Δ2>+Δth, it is determined that P2 is the end point of the rising edge within the current pulse period.

[0041] Regarding Situation 2, there are two changes that do not satisfy the condition where the absolute value is 0 or greater and less than the predetermined judgment threshold Δth. For example, the power values ​​of three consecutively acquired sampling points are P1=16W, P2=12W, and P3=11W, respectively. The power changes obtained by sequentially subtracting the acquired power values ​​are Δ1=P1-P2=4>+Δth and Δ2=P2-P3=2W>+Δth, respectively. Here, Δ1>+Δth and Δ2>+Δth, meaning that if there are two power changes where the absolute value is ≥ the predetermined judgment threshold Δth, the collected data is inaccurate. In this case, the data for sampling points P1, P2, and P3 are discarded, meaning the data for sampling points P1, P2, and P3 are set to 0, a null signal value, or a low signal level. Furthermore, if the power change Δ1>+Δth and the power change Δ2>+Δth, it is determined that the current sampling point is within the rising edge interval and the power change is continuously increasing.

[0042] Example 2: Determination and processing of situations related to falling edges

[0043] Within one pulse period, the power values ​​at the acquisition points are calculated sequentially, and when different power values ​​change, the falling edge determination result and processing method are as follows, with Δth = 1.5W.

[0044] For situation 1, there is one change in which the absolute value is greater than or equal to a predetermined threshold Δth. 2-1. For example, the power values ​​of three consecutively acquired sampling points are P1=17W, P2=19W, and P3=20W, respectively. The power changes obtained by sequentially subtracting the acquired power values ​​are Δ1=P1-P2=-2 and Δ2=P2-P3=-1W, respectively. Here, Δ1<-Δth and 0>Δ2>-Δth. That is, if there is one change where the absolute value ≥ a predetermined threshold Δth, the collected data is inaccurate. In this case, the data from sampling points P1, P2, P3 or P1, P2 are discarded. That is, the data from sampling points P1, P2, P3 or P1, P2 are set to 0, a null signal value, or a low signal level. Furthermore, if the power change Δ1<-Δth occurs for the first time within the current pulse period and 0>Δ2>-Δth, it is determined that P2 is the starting point of the falling edge within the current pulse period.

[0045] 2-2. For example, the power values ​​of three consecutively acquired sampling points are P1=8W, P2=9W, and P3=11W, respectively. The power changes obtained by sequentially subtracting the acquired power values ​​are Δ1=P1-P2=-1W and Δ2=P2-P3=-2W, respectively. Here, 0>Δ1>-Δth and Δ2<-Δth, meaning that if there is one change where the absolute value ≥ a predetermined threshold Δth, the collected data is inaccurate. In this case, the data for sampling points P1, P2, P3 or P2, P3 is discarded, meaning the data for sampling points P1, P2, P3 or P2, P3 is set to 0, a null signal value, or a low signal level. Furthermore, if 0>Δ1>-Δth occurs for the first time in the current pulse period for a power change, and Δ2<-Δth, it is determined that P2 is the end point of the falling edge in the current pulse period.

[0046] Regarding Situation 2, there are two change amounts whose absolute value is greater than or equal to 0 and less than a predetermined judgment threshold Δth. For example, the power values ​​of three consecutively acquired sampling points are P1=8W, P2=10W, and P3=14W, respectively. The power change amounts obtained by sequentially subtracting the acquired power values ​​are Δ1=P1-P2=-2<-Δth and Δ2=P2-P3=-4W<-Δth, respectively. Here, Δ1<-Δth and Δ2<-Δth, meaning there are two change amounts whose absolute value is greater than or equal to the predetermined judgment threshold Δth. In this case, the data for sampling points P1, P2, and P3 are discarded, meaning the data for sampling points P1, P2, and P3 are set to 0, a null signal value, or a low signal level. Furthermore, if the power change amounts Δ1<-Δth and Δ2<-Δth, it is determined that the current sampling point is within a falling edge interval and the power change amounts are continuously decreasing.

[0047] The technical solution provided by this embodiment involves detecting the slope of the feedback signal to determine the ramp section, determining whether the collected data is accurate, retaining the collected data if it is accurate, and otherwise setting the abnormal data bits to 0, a null signal value, or a low signal level, or skipping the abnormal data when outputting the data. This allows for determining whether the collected data is accurate based on the slope of the collected signal, calibrating inaccurate ramp signals collected during high-frequency power supply switching and in PULSE mode, and ultimately ensuring the accuracy of the calculated power and resistance values.

[0048] Example 3 As shown in Figure 6, an embodiment of the present invention is: A pulse ramp determination module 61 for determining the rising edge section and falling edge section within the current pulse period based on the power change amount of consecutive sampling points and a predetermined determination threshold, An abnormal data bit determination module 62 for determining abnormal data bits corresponding to rising edge intervals and falling edge intervals in the sampling sequence, An abnormal data bit processing module 63 for setting abnormal data bits to 0, a null signal value, or a low signal level value, or for skipping the output of abnormal data bits when outputting sampled data, The present invention further provides a high-frequency power supply signal acquisition device comprising a sampling data output module 64 for the sampling array to read and sequentially output sampling data outside of rising edge and falling edge intervals.

[0049] In several selectable embodiments, as shown in the dashed area of ​​Figure 6, the pulse lamp determination module 61 is: A signal acquisition submodule 611 for continuously acquiring high-frequency power supply signals from at least three sampling points in a time series, A power determination submodule 612 for determining the power of each sampling point based on a high-frequency power supply signal, A power change acquisition submodule 613 sequentially subtracts the power values ​​of each acquired sampling point and acquires at least two power change amounts for any two adjacent sampling points, The system includes a ramp determination submodule 614 for determining the rising edge and falling edge sections within the current pulse period based on the power change and a predetermined determination threshold.

[0050] In several selectable embodiments, the lamp determination submodule 614 is: A rule determination unit for determining the rules for changes in power change, The system includes a ramp determination unit for determining whether the current sampling point is within a rising edge interval or a falling edge interval if at least one of the power change amounts is above or below a predetermined determination threshold. Specifically, in some embodiments, if two consecutive power change amounts have opposite directions of change and both are below a predetermined determination threshold, it is determined that the signal at the current sampling point is in a fluctuating state; otherwise, it is determined that the current sampling point is not within a rising edge interval or a falling edge interval.

[0051] In several selectable embodiments, a predetermined threshold is Δth, where 0 < Δth, and at least two power changes of any two adjacent sampling points include Δ1 and Δ2, where the power change continuously exceeds or falls below the predetermined threshold means that when the power change is continuously increasing, the equations +Δth ≤ Δ1 and +Δth ≤ Δ2 are simultaneously true, and when the power change is continuously decreasing, the equations Δ1 ≤ -Δth and Δ2 ≤ -Δth are simultaneously true.

[0052] Two consecutive power changes having opposite directions of change and both being below a predetermined threshold means that the equations 0 ≤ Δ1 < Δth and -Δth < Δ2 ≤ 0 are simultaneously true, or that the equations -Δth < Δ1 ≤ 0 and 0 ≤ Δ2 < Δth are simultaneously true.

[0053] In some of the selectable embodiments, as shown in the dashed area of ​​Figure 6, the apparatus is The system further includes an array output module 64 for reading and sequentially outputting sampled data from the sampling array outside of the rising edge interval and falling edge interval.

[0054] The technical solution provided by this embodiment involves detecting the slope of the feedback signal to determine the ramp section, determining whether the collected data is accurate, retaining the collected data if it is accurate, and otherwise setting the abnormal data bits to 0, a null signal value, or a low signal level, or skipping the abnormal data when outputting the data. This allows for determining whether the collected data is accurate based on the slope of the collected signal, calibrating inaccurate ramp signals collected during high-frequency power supply switching and in PULSE mode, and ultimately ensuring the accuracy of the calculated power and resistance values.

[0055] Example 4 Based on a similar technical concept, an embodiment of the present application further provides a computer device comprising a memory 1 and a processor 2, as shown in Figure 6, in which a computer program is stored in the memory 1, and when the computer program is executed by the processor 2, the method for acquiring high-frequency power supply signals described in any one of the above is realized.

[0056] Here, memory 1 includes at least one type of readable storage medium, which includes flash memory, hard disk, multimedia card, card-type memory (e.g., SD or DX memory), magnetic memory, magnetic disk, optical disk, etc. In some embodiments, memory 1 may be an internal storage unit of the OTT video service monitoring system, such as a hard disk. In some other embodiments, memory 1 may be an external storage device of the OTT video service monitoring system, such as a plug-in hard disk, Smart Media Card (SMC), Secure Digital (SD) card, or flash card. Furthermore, memory 1 may include both an internal storage unit and an external storage device of the OTT video service monitoring system. Memory 1 may be used to store various types of data, such as application software installed on the OTT video service monitoring system and the code of the OTT video service monitoring program, as well as to temporarily store data that has already been output or data that is to be output.

[0057] In some embodiments, the processor 2 may be a central processing unit (CPU), a controller, a microcontroller, a microprocessor, or other data processing chip, and is used to execute program code stored in memory 1 or process data, for example, to execute an OTT video service monitoring program.

[0058] The technical solution provided by this embodiment involves detecting the slope of the feedback signal to determine the ramp section, determining whether the collected data is accurate, retaining the collected data if it is accurate, and otherwise setting the abnormal data bits to 0, a null signal value, or a low signal level, or skipping the abnormal data when outputting the data. This allows for determining whether the collected data is accurate based on the slope of the collected signal, calibrating inaccurate ramp signals collected during high-frequency power supply switching and in PULSE mode, and ultimately ensuring the accuracy of the calculated power and resistance values.
