Description

Technical Field

[0001] This application claims the priority of a Chinese patent application with application number 202311600510.8, filed with the China National Intellectual Property Administration on November 28, 2023, the content of which is incorporated herein by reference in its entirety.

[0002] This application relates to the technical field of signal processing, for example, to a waveform selection method, apparatus, device, and storage medium.

Background Art

[0003] A digital oscilloscope is a widely used electronic test and measurement instrument, which has multiple channels for receiving signals. When the digital oscilloscope receives signals from at least one device under test, waveforms corresponding to these signals can be simultaneously displayed on the display via each channel.

[0004] In a digital oscilloscope, since waveforms of more than one channel may be displayed in the same waveform display area, when a user attempts 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 clicking with a finger touch or a mouse pointer. At this time, the user must click on the target waveform on the oscilloscope display to separate it from other waveforms so that the finger or mouse pointer does not touch other waveforms. However, on an oscilloscope display with a limited screen size, it is common for waveforms of multiple channels to be displayed overlapping, and in many cases, it is difficult to find a large area where the target waveform can be distinguished from other waveforms. In addition, even if two waveforms appear to be separated on the screen, since both a click by finger touch and a click by mouse pointer have a response area of a certain size, the user may touch multiple waveforms when actually clicking to select, and at this time, the digital oscilloscope may select a non-target waveform, leading to an incorrect response.

Modes for Carrying Out the Invention

[0017] To enable those skilled in the art to better understand the aspects of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

[0018] In addition, the terms "first", "second", "target", etc. in the specification, claims and above drawings of the present application are for distinguishing similar objects and do not necessarily need to be used to explain a specific order or sequence. It should be understood that the data used in this way can be appropriately exchanged so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here. Also, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units specifically listed, and may include other steps or units not specifically listed or inherent to these processes, methods, products or devices.

[0019] Example 1 Figure 1 is a flowchart of a waveform selection method according to Embodiment 1 of the present invention, which is applicable when selecting one waveform from a plurality of waveforms displayed on the display of an electronic test and measurement device by clicking, and the method can be performed by a waveform selection device, which can be implemented in hardware and / or software form, and which can be installed in an electronic test and measurement device. As shown in Figure 1, the method includes S110 to S140.

[0020] S110: Determines the click location on the display in response to the user's click operation.

[0021] The waveform selection method according to this embodiment may be used in electronic test and measurement equipment such as digital oscilloscopes, or in other electronic devices. In this embodiment, the example mainly shows a user selecting one of the channel waveforms displayed on the display of an electronic test and measurement equipment.

[0022] In this embodiment, the display of the electronic test and measurement device may show waveforms corresponding to multiple channels, and when a user attempts to select one of these channel waveforms, a corresponding click operation may occur. When the electronic test and measurement device receives a click operation from the user, it can record the position of the click on the display made by the user.

[0023] In one embodiment, the click operation may include both a touch click operation on the display and a mouse click operation.

[0024] In practical applications, users can perform click operations by directly touching the display, including touching the display with their fingers or using a stylus. When a user performs a click operation by touching the display, the click position can be defined as the point of contact between the finger and the display, or the point of contact between the tip of the stylus and the display. If the display is a capacitive screen, the user's touch position can be determined by measuring the change in capacitance of the capacitive screen, and the coordinates of the click position can be calculated according to the timing of the touch event. If the display is a resistive touchscreen, the user's touch position can be detected by the change in resistance between two conductive thin films. If the display is an infrared touchscreen, the position of the touch point can be detected by the emission and reception of an infrared beam, and when a touch occurs, the beam is interrupted, and the click position is determined.

[0025] The user may use a mouse to perform click operations on the display. By moving the mouse, the user can move the mouse pointer on the display accordingly, and when the user clicks the mouse, the position pointed to by the mouse pointer is considered the click location.

[0026] It should be understood that the click operation in this embodiment is not limited to touch clicks on a display or clicks using a mouse. The waveform selection method in this embodiment can respond to any click operation that can be supported by other technologies.

[0027] S120: Determines the waveform selection area based on the click position.

[0028] In this embodiment, in order to reduce the probability of incorrect waveform selection due to display congestion and misalignment of user click operations, waveform selection and determination may not simply use the click position, but rather comprehensively determine which channel waveform on the display best matches the user's selection intent by using the waveform selection area associated with the click position.

[0029] In one embodiment, S120 can be realized in the following form.

[0030] The display area that includes the click position and has a pre-set calculated area is defined as the waveform selection area.

[0031] In actual applications, the area size of the waveform selection region can be determined according to the usage scenario. After clicking a position, the area near the clicked position with a pre-set calculated area may be recorded as the waveform selection region.

[0032] For example, the click position is located at the center of the waveform selection area, and the waveform selection area is circular or quadrilateral.

[0033] Generally, although there may be discrepancies in the user's click position on the display, the click position can basically reflect the approximate position of the waveform the user intends to select. Therefore, by determining the waveform selection area around the click position, the probability of correct waveform selection can be improved. Generally, for ease of calculation, the waveform selection area may be circular or quadrilateral.

[0034] It should be understood that the click location can be anywhere within the waveform selection area, such as the vertices or sides of a right quadrilateral.

[0035] In specific examples, a square with the click position as the center and the first length as the side length can be determined as the waveform selection area; a circle with the click position as the center and the second length as the radius can be determined as the waveform selection area; a rectangle with the click position as the center and the third length as the longer side and the fourth length as the shorter side can be determined as the waveform selection area; and a square with the top-left corner vertex as the click position and the first length as the side length can be determined as the waveform selection area.

[0036] S130: Determine the waveform energy of each of the multiple channel waveforms within the waveform selection region.

[0037] In this embodiment, by statistically calculating the waveform energy corresponding to each channel waveform included within the waveform selection region, it is possible to reflect the distribution of multiple channel waveforms within the waveform selection region.

[0038] In one embodiment, S130 can be realized in the following form.

[0039] For each channel waveform contained within the waveform selection region, the waveform energy of the channel waveform is defined as the integral of the waveform brightness area of ​​the channel waveform within the waveform selection region.

[0040] For example, the waveform energy within the waveform selection region of a channel waveform can refer to the cumulative sum of the luminance of each waveform point constituting the channel waveform within the waveform selection region; in other words, it is the integral of the waveform luminance and area within the waveform selection region, and can be expressed roughly as follows.

[0041] Waveform energy = Σ; Brightness of a wave point = ∫ Waveform brightness * Area.

[0042] S140: Select a target waveform from multiple channel waveforms based on the waveform energy of the multiple channel waveforms.

[0043] In this embodiment, the waveform energy of a channel waveform can reflect the distribution of that channel waveform within the waveform selection region. Therefore, by analyzing the waveform energy of each channel waveform, a target waveform that aligns with the user's intended choice can be selected.

[0044] In one embodiment, S140 can be realized in the following form.

[0045] Based on the waveform energy of multiple channel waveforms, the energy ratio of each channel waveform within the waveform selection region is determined, and the channel waveform with the highest energy ratio is selected as the target waveform for the user.

[0046] It should be understood that if a channel waveform has a high energy ratio within the waveform selection region, it indicates that the user's click at that location is more in line with their intention to select that channel waveform, and therefore the channel waveform with the highest energy ratio within the waveform selection region can be determined as the target waveform to be selected by the user.

[0047] In particular, if the waveform energy of multiple channel waveforms within the waveform selection area is all lower than a preset energy threshold, the user's click operation can be considered an error, and no channel waveforms can be selected, allowing for an appropriate presentation on the display.

[0048] Figure 2 is a schematic diagram illustrating the principle of the waveform selection method according to Embodiment 1 of the present invention. As shown in Figure 2, channel waveform 1 and channel waveform 2, which are close in waveform distance, are displayed simultaneously on the display of the electronic test and measurement equipment. When a user needs to select channel waveform 1, they touch the display with their finger or click with a mouse, and the black dot in the figure indicates the user's click position. A display area with a preset calculation area centered on the click position is defined as the waveform selection area, for example, the display area shown by the dashed rectangular frame in the figure. By calculating the waveform energy within the dashed rectangular frames of channel waveform 1 and channel waveform 2, it can be seen that the energy ratio of channel waveform 1 is higher than that of channel waveform 2, and therefore channel waveform 1 is selected as the target waveform.

[0049] In the present invention's embodiment, in response to a user's click operation, the click position on the display is determined, a waveform selection area is determined based on the click position, the waveform energy of multiple channel waveforms within the waveform selection area is determined, and a target waveform is selected from the multiple channel waveforms according to the waveform energy of the multiple channel waveforms. In the present invention's embodiment, multiple channel waveforms are displayed simultaneously on the display, the waveforms overlap, and the user's click area is ambiguous, thus avoiding the problem of being unable to correctly select the waveform the user needs. Therefore, the user's click intent when selecting a waveform can be effectively recognized, and the accuracy of waveform selection can be improved.
