Pulse detecting system and method

Abstract

The invention provides a pulse detecting system and method. The pulse detecting system comprises a graphene sensor, a piezoelectric conversion circuit, an analog-digital converter, a processor, a digital-analog converter and a display, wherein the graphene sensor is used for detecting pulse information of a user; the piezoelectric conversion circuit is connected with the graphene sensor, and is used for converting the pulse information detected by the graphene sensor into a first analogy signal; the analog-digital converter is connected with the piezoelectric conversion circuit, and is used for converting the first analogy signal into a digital signal; the processor is connected with the analog-digital converter, and is used for processing the digital signal to extract a whole pulse signal; the digital-analog converter is connected with the processor, and is used for converting the whole pulse signal into a second analogy signal; the display is connected with the digital-analog converter, and is used for outputting and displaying the second analogy signal. The pulse detecting system provided by the invention is realized through traditional analog-digital converter and digital-analog converter, the hardware circuit structure is simple, and the graphene sensor in the system is low in cost, can be used without the limitation of environment, and is low in energy consumption.

Description

technical field [0001] The invention relates to the technical field of medical detection, and more specifically, to a pulse detection system and method. Background technique [0002] Pulse condition refers to the image of the pulse that the doctor feels with his fingers, including the depth of the arterial pulse, the speed of the pulse, the size of the intensity, the uniformity of the rhythm, etc. Through the diagnosis of the pulse condition, a person's health can be judged . [0003] The traditional pulse detection method is generally judged by the doctor's feeling, and due to the different knowledge, experience and other factors of each person, the feeling and judgment of the pulse condition will also be inconsistent, so the pulse detection results obtained by the traditional pulse detection method are different. The error is large. Based on this, the existing technology proposes a reflective photoelectric pulse measurement technology, which is based on the principle tha...
