Method and device for horizontal movement of waveform based on touch screen

Abstract

The invention relates to a method for horizontal movement of a waveform based on a touch screen. The method comprises the following steps that a first coordinate area, an element used or indicating a range and a second coordinate area used for amplifying and displaying the waveform in the element are set; whether a touch is conducted is detected, if yes, whether sliding occurs on the touch screen or in the first coordinate area or in the second coordinate area is judged, and if yes, the waveform in the first coordinate area or the second coordinate area is controlled to move horizontally or shift according to the sliding in the first coordinate area, and the element is controlled to move horizontally or shift according to the sliding in the second coordinate area; otherwise, a corresponding interface is switched to, or a current interface is maintained; whether a command of quitting current detection is received is judged, if yes, the current detection is quitted, and if not, the steps are executed again. The invention further relates to a device for implementing the method. The method and device for horizontal movement of the waveform based on the touch screen have the advantages that operation is visual, the utilization rate of effective display space is high, the service life is long, and cleaning is easy.

Description

technical field [0001] The present invention relates to the field of touch screens, and more specifically, to a method and device for waveform translation based on a touch screen. Background technique [0002] With the increase of the storage depth of the oscilloscope, in order to view the details of the waveform more clearly, the zooming of the waveform has become an essential function of the oscilloscope. The display modes of the oscilloscope include general display mode and waveform zoom display mode. This function can be better The waveform can be displayed accurately, which can not only take a look at the overall situation, but also check the details, which greatly facilitates the debugging of engineers. In the waveform zoom display mode, the display content of the waveform zoom window is an enlarged display of a certain part of the content in the normal waveform display window in the horizontal direction. In the normal waveform display window, the enlarged part is dis...
