A kind of control method of pulse signal detection

Abstract

The invention discloses a control method for pulse signal detection. By setting the pulse signal measurement stability criterion, when the measured pulse signal does not satisfy the pulse signal measurement stability criterion, the cached data is discarded. When the measured pulse signal satisfies the pulse signal measurement stability criterion, the buffered N pieces of pulse wave data are sent to the signal receiving end. The number of pulse waves N to be measured can be set. When the measured population is an ordinary healthy population, N can be set to a relatively small value. When the measured population is a sick population, N can be set to a relatively large value. . The method can measure stable and effective pulse signals with different lengths and can be set for different groups of people, reduce the power consumption of the acquisition end and the difficulty of data processing at the signal receiving end, and improve the efficiency of pulse signal detection.

Description

technical field [0001] The invention relates to the technical field of physiological signal detection, in particular to a control method for pulse signal detection. Background technique [0002] Pulse is an important indicator of human life activities. The pulse signal contains rich physiological and pathological information, which is closely related to cardiovascular diseases. By measuring and analyzing the human pulse signal, the health status of the human body can be effectively monitored. In the process of pulse signal acquisition, the movement displacement of the human body relative to the pulse measuring device will cause the measured pulse wave waveform to be high and sometimes low, and there will be a large baseline drift, resulting in irregular pulse waveforms. These pulse data are not valid data. Difficult to extract accurate information from it. Secondly, in the case of stable measurement, the pulse wave of the human body pulse signal in a certain period of time ...
