In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. According to the technical scheme, the data acquisition, storage, use, processing and the like meet relevant regulations of national laws and regulations.
Example one
Fig. 1A is a flowchart of a method for marking a test curve according to an embodiment of the present invention, where the method is applicable to a scenario where a test curve is marked during an electromagnetic compatibility test, and the method may be executed by a device for marking a test curve, where the device may be implemented in a form of hardware and/or software, and the device may be configured in an electronic device. As shown in fig. 1A, the method includes:
and S110, if the marking trigger event is detected, determining the target position of the test curve to be marked.
The scheme can be executed by a test system, and the test system can generate a frequency spectrum curve after the electromagnetic compatibility test. It will be appreciated that the test curve to be marked may comprise a spectral curve. By detecting the marker trigger event, the test system can mark the test curve to be marked. The marking trigger event may be the completion of the electromagnetic compatibility test, or the reaching of a preset test curve marking time. The tester can process the test curve by operating the test system, and the marking trigger event can also be detecting operations such as mouse click, key press and the like, for example, pressing a test curve marking shortcut key.
If a marking trigger event is detected, the test system can determine the target position of the test curve to be marked according to the current pointer, the cursor and other position indication marks, and can also determine the target position of the test curve to be marked according to a preset position coordinate list file. The target position may be a position where the test curve to be marked needs to be marked.
And S120, generating at least two reference lines of the test curve to be marked according to the target position and preset segmentation parameters.
Fig. 1B is a labeled schematic diagram of a spectral curve provided according to an embodiment of the invention. As shown in FIG. 1B, the spectral curves generated by the EMC test typically relate to a range of frequencies, such as 30MHz-1 GHz. The test system is difficult to mark on the whole spectrum curve, so the spectrum curve can be divided, and each divided curve segment can be marked. The test system can divide the test curve to be marked into curve segments according to equal or unequal frequency ranges according to the dividing parameters. It will be readily appreciated that the segmentation parameter may include the number of segments, for example, a segmentation parameter of 10. According to the segmentation parameters, the test system can divide the frequency range such as the test curve to be marked into 10 sections. The test system can mark curve segments in the mark range by taking the frequency range matched with the target position as the mark range, and can also determine a mark range by taking the target position as the center according to the frequency range obtained by dividing the segmentation parameters, and mark the test curve to be marked in the mark range. The test system can generate a reference line on the boundary of the marking range and can also generate a reference line on the target position so as to visually observe the change of the target position. The reference line may be a straight line or a curved line, and may further have a symbol mark to distinguish the marking task.
It should be noted that the segmentation parameters may include one or more segmentation parameters, and the test system may display the target position and the marker ranges determined by the segmentation parameters, respectively, and display different reference lines differently. For example, the segmentation parameters may include 10 and 8, the test system may divide the frequency range of the test curve to be marked into 10 segments, divide the frequency range of the test curve to be marked into 8 segments, determine two marking ranges according to the target position and the frequency ranges determined by the two segmentation parameters, and further generate 4 reference lines perpendicular to the abscissa of the test curve to be marked.
S130, determining the marking position of the test curve to be marked according to the at least two reference lines, and marking according to the marking position.
It will be readily appreciated that the test system may determine at least one marker range, which may be a frequency range, for example, from at least two reference lines. The test system can determine the marking position on the test curve to be marked in the marking range, wherein the marking position can comprise the position of the test curve to be marked, which takes the maximum value in the marking range, can also comprise the position of the test curve to be marked, which takes the minimum value, and can also comprise the position of the test curve to be marked, which takes the abnormal value. Depending on the marking location, the test system may be marked with the same or different markings, for example diamond markings for the maximum location and circular markings for the minimum location.
According to the technical scheme, when a marking trigger event is detected, the target position of a test curve to be marked is determined, and at least two reference lines of the test curve to be marked are generated according to the target position and preset segmentation parameters; and determining the marking position of the test curve to be marked according to the at least two reference lines so as to mark according to the marking position. The scheme solves the problems that the amplification marking mode is low in efficiency, the accuracy is difficult to guarantee and the like, can reduce the marking deviation while improving the marking efficiency, and further achieves a good marking effect.
Example two
Fig. 2 is a flowchart of a method for marking a test curve according to a second embodiment of the present invention, which is detailed based on the second embodiment. As shown in fig. 2, the method includes:
s210, if the marking trigger event is detected, determining the target position of the test curve to be marked.
In this scheme, the test curve to be marked may be a spectrum curve as shown in fig. 1B, the mark triggering event may be a shortcut key press indicating a mark, the target position may be a position of the test curve to be marked indicated by a cursor, and the segmentation parameter may be the number of segments.
And S220, calculating a segmentation average value according to the preset segmentation parameters and the frequency range related to the test curve to be marked.
According to the frequency range and the segmentation parameters related to the test curve to be marked, the test system can calculate to obtain the segmentation average value. Wherein the segmentation average value represents the frequency interval involved by each segmentation segment after the frequency range involved by the test curve to be marked is equally divided. Specifically, the calculation formula of the segmentation average value is as follows:
wherein,
representing the maximum frequency to which the test curve to be marked relates,
representing the minimum frequency to which the test curve to be marked relates,
representing preset segmentation parameters.
And S230, determining a first reference position and a second reference position according to the target position and the segmentation average value.
As shown in FIG. 1B, the circular marker location may be a target location, which may be represented as coordinates
. It will be readily appreciated that the test system may maintain the ordinate of the target position constant and determine two reference positions, such as the triangle marker positions of FIG. 1B, based on the abscissa of the target position and the segmentation average. It will be appreciated that the abscissa of the spectral curve can be directly represented by a linear axis. In order to conveniently and clearly show the change condition of the curve, the frequency spectrum curve logarithmically converts the linear abscissa so as to stretch the small coordinate value and compress the large coordinate value.
In one possible embodiment, the first reference position is transverse to the test curve to be marked if it is displayed in a semilogarithmic coordinate systemThe coordinate calculation formula is as follows:
the abscissa calculation formula of the second reference position is as follows:
;
in another possible solution, if the test curve to be marked is displayed in a linear coordinate system, the abscissa calculation formula of the first reference position is:
the abscissa calculation formula of the second reference position is as follows:
；
wherein,
the abscissa representing the position of the target is,
the division average value is shown.
S240, generating a first reference line perpendicular to the abscissa of the test curve to be marked at the first reference position, and generating a second reference line perpendicular to the abscissa of the test curve to be marked at the second reference position.
As shown in fig. 1B, the test system may generate a first reference line perpendicular to the abscissa of the test curve to be marked according to the first reference position, a second reference line perpendicular to the abscissa of the test curve to be marked according to the second reference position, and a center reference line perpendicular to the abscissa of the test curve to be marked according to the target position.
The scheme uses a target position as a center, determines a frequency range according to a segmentation average value, and marks a test curve to be marked in the frequency range. According to the scheme, a reasonable marking range can be set for marking the target position, so that regional marking of the test curve to be marked is facilitated, and the marking accuracy and efficiency are improved.
S250, determining a first frequency of the test curve to be marked according to the first reference line, and determining a second frequency of the test curve to be marked according to the second reference line.
It will be readily appreciated that the first reference line and the second reference line correspond to two frequencies on the test curve to be marked, respectively. For example, the first frequency corresponding to the first reference line shown in fig. 1B may be the abscissa of the first reference position in the linear coordinate system, and the second frequency corresponding to the second reference line may be the abscissa of the second reference position in the linear coordinate system.
S260, determining a frequency interval according to the first frequency and the second frequency, and determining the maximum amplitude value of the test curve to be marked in the frequency interval.
Assuming that the first frequency is
The second frequency is
The frequency interval may be
. The test system can screen out amplitude data in a frequency range on the test curve to be marked and determine the maximum value in the amplitude data. It can be understood that the frequency point with the maximum amplitude in each frequency interval is usually a risk point concerned in the electromagnetic compatibility test process, and the read point test can be conveniently performed by marking the risk point.
S270, determining the marking position of the test curve to be marked according to the maximum amplitude value, and marking according to the marking position.
After the amplitude maximum value in the frequency interval is determined, the test system can determine the marking position according to the amplitude maximum value and the frequency point corresponding to the amplitude maximum value, and further mark the marking position. Mark position 1, mark position 2 and mark position 3 as indicated by the diamond symbols in fig. 1B.
In this embodiment, optionally, after determining the frequency interval according to the first frequency and the second frequency, the method further includes:
if a correction trigger event is detected, determining the amplitude average value of the test curve to be marked in the frequency interval;
and correcting the amplitude of the test curve to be marked in the frequency interval according to the comparison result of the amplitude of each frequency point in the frequency interval and the amplitude average value and a preset correction principle.
The test system can also identify and correct abnormal interference signals appearing in the test curve to be marked. Specifically, if the test system detects a correction trigger event such as pressing of a correction shortcut key, inputting of a correction command, and the like, the average amplitude value may be calculated according to the amplitude data within the frequency interval range on the test curve to be marked. According to the comparison result of the amplitude of each frequency point in the frequency interval and the average value of the amplitude, the test system can determine whether the amplitude value of the frequency point is abnormal or not, and then the abnormal amplitude value is corrected.
On the basis of the above scheme, the correcting the amplitude of the test curve to be marked in the frequency interval according to the comparison result between the amplitude of each frequency point in the frequency interval and the amplitude average value and according to a preset correction principle includes:
if the amplitude of the frequency points in the frequency interval is larger than the amplitude average value, the amplitude value is reduced at least once according to a preset amplitude adjustment value until the amplitude is lower than a preset amplitude limit value.
If the amplitude of the frequency point in the frequency interval is larger than the amplitude average value, the amplitude of the frequency point is indicated to be at risk, and the test system can reduce the amplitude value of the amplitude of the frequency point at least once according to a preset amplitude adjustment value, such as 1dB, until the amplitude limit value is met. For example, the amplitude of the frequency point at the mark position 3 in fig. 1B is much higher than the amplitude limit value, the test system can correct the amplitude value by successive fine adjustment to keep the amplitude value within a reasonable amplitude range, thereby correcting the abnormal amplitude value caused by the interference signal in the test process.
According to the technical scheme, when a marking trigger event is detected, a target position of a test curve to be marked is determined, and at least two reference lines of the test curve to be marked are generated according to the target position and preset segmentation parameters; and determining the marking position of the test curve to be marked according to the at least two reference lines so as to mark according to the marking position. The scheme solves the problems that the amplification marking mode is low in efficiency, the accuracy is difficult to guarantee and the like, can reduce the marking deviation while improving the marking efficiency, and further achieves a good marking effect.
