Abstract

The invention discloses a coordinate switching method for waveform drawing. The method comprises the following steps of segmenting waveforms displayed by a respirator according to each respiration period; obtaining an extreme value of waveform data of each respiration period; when the extreme values of the waveform data of a preset number of continuous respiration periods exceed a preset coordinate range switching interval, controlling a current coordinate range to be switched to a first coordinate range; when the extreme values of the waveform data of a preset number of continuous respiration periods are in the preset coordinate range switching interval, controlling the current coordinate range to be switched to a second coordinate range, wherein the second coordinate range is smaller than the first coordinate range. According to the coordinate switching method, frequent coordinate switching during the jittering of the waveform data on the edges of the coordinate ranges can be avoided, and meanwhile, the amplitude of the waveforms in coordinates is also limited, so that waveform drawing is optimized, good presentation effects are ensured, and attractive visual effects are achieved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a coordinate switching method for waveform drawing. Background technique [0002] At present, many products have the function of drawing the collected data into a waveform display, and as long as the waveform is quantitatively displayed, it involves the switching of the coordinate range. The existing switching algorithm simply uses the maximum range of the current coordinates to judge whether to switch to a larger coordinate to draw the waveform, so the rendering effect of the waveform is not considered. In this way, when the collected data is jittering at the edge of the coordinate range, the switching of the coordinates will be too frequent, resulting in a full-scale display of the waveform, and the display effect is not ideal. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned technical defects at least to a cer...
