Embodiment 1

[0026] A method for drawing signal change diagrams disclosed in the present application, such as figure 1 As shown, the method includes: step 100 to step 120.

[0027] Step 100, acquire signals to be plotted arranged in order of acquisition time, where the signals to be plotted include amplitude values.

[0028] In the signal detection process, a certain number of signal values ​​of the signals to be detected are usually collected first, and then a signal change diagram of the signals to be detected is drawn according to the collected signal values ​​of the certain number of signals to be detected, so as to visually judge the signal value of the signal to be detected. Describe the change of the signal to be detected. During specific implementation, the collected signal value of the signal to be detected is the signal amplitude, and the collected signal of the signal to be detected also has an attribute of collection time. During specific implementation, the collected signals...

Embodiment 2

[0038] A method for drawing a signal change diagram disclosed in the embodiment of the present application, such as figure 2 As shown, the method includes: Step 200 to Step 250.

[0039] Step 200, collecting signals to be drawn.

[0040]The signal to be drawn in this application may be an electrical signal such as a voltage signal, a current signal, or a power consumption signal. Different signal acquisition methods are different. In this embodiment, only the collected signal to be drawn is a current signal as an example for illustration. The signal to be drawn in this application may be an electrical signal collected from any electronic device, such as a PC, a mobile terminal, a personal digital assistant, a tablet computer, a TV, an electronic door lock, and the like. Different electronic devices have different signal change frequencies, so before collecting signals, set a corresponding sampling frequency according to the signal change frequency of the electronic device t...

Embodiment 3

[0060] Correspondingly, the embodiment of the present application discloses a signal change graph drawing device, such as Figure 6 As shown, the device includes:

[0061] The signal to be drawn acquisition module 600 is used to acquire the signals to be drawn arranged in the order of acquisition time, and the signal to be drawn includes amplitude and acquisition time;

[0062] A judging module 610, configured to judge whether the amplitude of the signal to be plotted meets a preset amplitude change condition;

[0063] Select the drawing module 620, for if the amplitude of the signal to be drawn meets the preset amplitude change condition, use the first coordinate mode to draw the signal change diagram of the signal to be drawn, otherwise, use the second coordinate mode to draw the signal change diagram Describe the signal change graph of the signal to be plotted.

[0064] optional, such as Figure 7 As shown, the selection drawing module 620 includes:

[0065] The first d...

Abstract

The invention provides a signal change graph drawing method, belongs to the technical field of a computer and is used for solving the problem that violently changed signals cannot be displayed visually through utilization of the signal change graph drawing method in the prior art. The method comprises the steps of obtaining to-be-drawn signals arranged according to a collection time sequence, wherein the to-be-drawn signals comprise amplitudes; judging whether the amplitudes of the to-be-drawn signals satisfy a preset amplitude change condition or not; and if the amplitudes of the to-be-drawn signals satisfy the preset amplitude change condition, drawing a signal change graph of the to-be-drawn signals in a first coordinate mode, otherwise, drawing the signal change graph of the to-be-drawn signals in a second coordinate mode. According to the method provided by the invention, for the signals collected in a time period during which the signals are changed violently and the signals collected in the time period during which the signals are changed stably, the signal change graph is drawn in different coordinate modes, the signals with relatively high amplitudes and the signals with relatively low amplitudes can be displayed at the same time, and the total signal change trend is grasped visually.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for drawing a signal change diagram, and electronic equipment. Background technique [0002] Display the detected signal by drawing a signal change diagram, which can intuitively show the change trend of the signal, such as: oscilloscope, signal analyzer. In the prior art, when drawing a signal change diagram, the signal acquisition time or the number of signal points is usually used as the abscissa, and the signal amplitude is used as the ordinate for drawing. When using the method in the prior art to draw a signal change diagram, when the signal change amplitude is relatively large, in order to present the entire signal amplitude, the usual practice is to continuously increase the value range of the ordinate, and correspondingly, the relative value of the ordinate The amplitude indicated between two adjacent coordinate scales will also increase....
