Embodiment Construction

[0039] The technical solution of the monitoring data waveform forming method and device will be described in detail below in conjunction with specific embodiments and accompanying drawings, so as to make it more clear.

[0040] Such as figure 1 Shown, in one embodiment, a kind of waveform formation method of monitoring data comprises the following steps:

[0041] Step S110, obtaining monitoring data.

[0042] In this embodiment, raw physiological data such as ECG, respiration, non-invasive blood pressure, blood oxygen saturation, pulse or body temperature are collected from the human body through sensors, and digitized physiological data are obtained through sampling, filtering, and encoding. The data is analyzed and processed to obtain monitoring data. The obtained monitoring data is in the form of data packets or messages, and the obtained monitoring data is saved in a buffer, such as a disk or a cache, and stored in the form of an array or a database, which is convenient f...

Abstract

The invention provides a waveshaping method and device for monitoring data. The method comprises the following steps: the monitoring data is acquired; whether the amount of the motoring data is less than the convention amount in the preset cache time is judged; if the amount of the motoring data is less than the convention amount, the deletion amount between the amount of the motoring data and the convention amount is acquired; uniform interpolation processing is performed to the motoring data according to the deletion amount, and the interpolation data is formed; the wave shape is formed according to the interpolation data. According to the waveshaping method and device for the motoring data, deletion data positions are uniformly distributed in the whole wave shape, and the wave shape distortion influence brought by the deletion data is dispersed, so that the wave shape distortion is reduced, and the accuracy of the wave shape is improved.

Description

technical field [0001] The invention relates to digital image technology, in particular to a monitoring data waveform forming method and device. Background technique [0002] The monitoring equipment obtains the patient's physiological data and displays the data waveform in real time. However, due to the clock difference or signal interference between the upper computer and the lower computer, the received data does not reach the agreed amount. When forming the data waveform, according to The last received data supplements the missing data to ensure the real-time display of the data waveform. [0003] However, when there are many missing data, a straight line will be drawn behind the waveform, and the more missing data, the more obvious the straight line phenomenon will be, resulting in waveform distortion. Contents of the invention [0004] Based on this, it is necessary to provide a monitoring data waveform formation method that can improve waveform accuracy for the wav...
