Description

Technical Field

[0001] The present invention relates to the technical field of signal processing, and particularly to a waveform selection method, device, equipment and storage medium. Background Art

[0002] A digital oscilloscope is a very widely used electronic test and measurement device, which has multiple channels for receiving signals. When the digital oscilloscope receives signals from one or more devices under test, the corresponding waveforms of these signals can be simultaneously displayed on the display through each channel.

[0003] Since the digital oscilloscope may display waveforms of more than one channel in the same waveform display area, when the user wants to adjust the waveform of a certain channel, it is necessary to first select the waveform corresponding to that channel. Generally, the user selects the target waveform by touching and clicking with a finger or clicking with a mouse pointer. At this time, the user must click on the target waveform on the oscilloscope display screen where it is separated from other waveforms so that the finger or mouse pointer does not touch other waveforms. However, the waveforms of multiple channels often overlap and are displayed on the oscilloscope display with a limited screen size. In many cases, it is difficult to find a large area that can distinguish the target waveform from other waveforms. In addition, even if two waveforms seem to be separated on the screen, due to the finger touch click and mouse pointer click both having a certain size of response area, the user may actually touch multiple waveforms when clicking and selecting, and at this time the digital oscilloscope may select a non-target waveform and respond incorrectly.

[0039] Embodiment 1

[0040] Figure 1 The present invention provides a flowchart of a waveform selection method for Embodiment 1. This embodiment is applicable to the case of clicking and selecting one waveform among multiple waveforms displayed on the display of an electronic test and measurement device. This method can be executed by a waveform selection device, which can be implemented in the form of hardware and / or software, and the waveform selection device can be configured in an electronic test and measurement device. As Figure 1 shown, the method includes:

[0041] S110. In response to the user's click operation, determine the click position on the display.

[0042] The waveform selection method provided in this embodiment can be applied to electronic test and measurement devices such as digital oscilloscopes, and can also be applied to other electronic devices. This embodiment mainly takes the example of a user selecting one of the channel waveforms displayed on the display of an electronic test and measurement device.

[0043] In this embodiment, the display of the electronic test and measurement device can display waveforms corresponding to multiple channels. When the user wants to select a certain channel waveform, there can be a corresponding click operation. When the electronic test and measurement device receives the user's click operation, it can record the click position of the user on the display.

[0044] In one embodiment, the click operation may include a touch display click operation and a mouse click operation.

[0045] In practical applications, the user can directly touch the display for a click operation, including touching the display with a finger or touching the display with a stylus. When the user performs a touch display click operation, the contact point position between the finger and the display can be used as the click position, or the contact point position between the tip of the stylus and the display can be used as the click position. When the display is a capacitive screen, the touch position of the user can be determined by measuring the capacitance change of the capacitive screen, and the coordinates of the click position can be calculated according to the timing sequence generated by the touch event; when the display is a resistive touch screen, the user touch position can be detected by the resistance change between two conductive films; when the display is an infrared touch screen, the position of the touch point can be detected by the emission and reception of infrared light beams. When a touch occurs, the light beam is blocked, thereby determining the click position.

[0046] The user can also use a mouse to perform a click operation on the display. The user can move the mouse to make the mouse pointer move correspondingly on the display. When the user clicks the mouse, the position of the mouse pointer is used as the click position.

[0047] It can be understood that the click operation in this embodiment is not limited to the touch display click operation and the mouse click operation. The waveform selection method of this embodiment can respond to click operations supported by other technologies.

[0048] S120. Determine the waveform selection area based on the click position.

[0049] In this embodiment, in order to reduce the probability of incorrect waveform selection caused by crowded display on the display and deviation in the user's click operation, the waveform selection is not simply determined using the click position. Instead, the waveform selection area associated with the click position is used to comprehensively judge which channel waveform on the display is more inclined to the user's selection intention.

[0050] In one embodiment, S120 can be implemented in the following manner:

[0051] Take the display area that contains the click position and has a pre-designed calculated area as the waveform selection area.

[0052] In practical applications, the area size of the waveform selection area can be determined according to the specific usage scenario. After the click position, the area near the click position with a pre-designed calculated area is recorded as the waveform selection area.

[0053] Furthermore, the click position is located at the center of the waveform selection area; the waveform selection area is circular or rectangular.

[0054] In general, although there may be deviations in the position where the user clicks on the display, the click position can basically reflect the approximate position of the waveform that the user wants to select. Therefore, determining the waveform selection area centered on the click position can increase the probability of correct waveform selection. In general, for the convenience of calculation, the waveform selection area can be a circle or a right-angled quadrilateral.

[0055] It can be understood that the click position can also be located at any position within the waveform selection area, such as at the vertex or on the side of a right-angled quadrilateral.

[0056] In a specific example, a square with the first length as the side length can be determined as the waveform selection area centered on the click position; a circle with the second length as the radius can be determined as the waveform selection area centered on the click position; a rectangle with the third length as the long side and the fourth length as the short side can also be determined as the waveform selection area centered on the click position; or a square with the first length as the side length can be determined as the waveform selection area with the click position as the upper left vertex.

[0057] S130. Determine the waveform energy of each channel waveform within the waveform selection area respectively.

[0058] In this embodiment, the waveform energy corresponding to each channel waveform included in the waveform selection area can be statistically calculated to reflect the distribution of each channel waveform within the waveform selection area.

[0059] In one embodiment, S130 can be implemented in the following manner:

[0060] For each channel waveform included in the waveform selection area, the integral of the waveform brightness area of the channel waveform within the waveform selection area is used as the waveform energy of the channel waveform.

[0061] Specifically, the waveform energy of the channel waveform within the waveform selection area can refer to the cumulative sum of the brightness of each waveform point that makes up the channel waveform within the waveform selection area, that is, the integral of the waveform brightness and the area within the waveform selection area, which can be approximately expressed as:

[0062] Waveform energy = ∑ waveform point brightness = ∫ waveform brightness * area.

[0063] S140. Select the target waveform from each channel waveform according to the respective waveform energies.

[0064] In this embodiment, the waveform energy of the channel waveform can reflect the distribution of the channel waveform within the waveform selection area. Therefore, by analyzing the waveform energy of each channel waveform, the target waveform with the user's selection intention can be selected.

[0065] In one embodiment, S140 can be implemented in the following manner:

[0066] According to the energy of each waveform, determine the energy proportion of each channel waveform within the waveform selection area; determine the channel waveform with the highest energy proportion as the target waveform selected by the user.

[0067] It can be understood that when the energy proportion of a channel waveform within the waveform selection area is high, it can indicate that the user is more inclined to select this channel waveform when clicking on this click position. Therefore, the channel waveform with the highest energy proportion within the waveform selection area can be determined as the target waveform selected by the user.

[0068] Specifically, when the waveform energy of each channel waveform within the waveform selection area is lower than the preset energy threshold, it can be considered that the user's click operation this time is a misoperation, and any channel waveform can not be selected, and a corresponding prompt is given on the display.

[0069] Figure 2 It is a schematic diagram of the principle of a waveform selection method provided by Embodiment 1 of the present invention. As Figure 2 shown, channel waveform 1 and channel waveform 2 with relatively close waveforms are simultaneously displayed on the display of the electronic test and measurement device. When the user needs to select channel waveform 1, the display is touched by finger or clicked by mouse, and the black dot in the figure represents the click position of the user. Taking the click position as the center, a display area with a pre-designed calculation area is divided as the waveform selection area, such as the display area shown by the dotted square in the figure. By calculating the waveform energy of channel waveform 1 and channel waveform 2 within the dotted square, it can be known that the energy proportion of channel waveform 1 is higher than that of channel waveform 2. Therefore, channel waveform 1 is selected as the target waveform.

[0070] The technical solution of the embodiment of the present invention determines the click position on the display in response to the user's click operation; determines the waveform selection area based on the click position; respectively determines the waveform energy of each channel waveform within the waveform selection area; and selects the target waveform from each channel waveform according to the waveform energy. The embodiment of the present invention avoids the problem that when multiple channel waveforms are simultaneously displayed on the display, the waveforms overlap and the user's click area is blurred, resulting in the inability to correctly select the waveform required by the user, and can effectively identify the click intention of the user when selecting a waveform, improving the accuracy of waveform selection.
