Abstract

An embodiment of the invention discloses a fatigue level analysis method and device based on pulse characteristics, wherein the method comprises: acquiring a pulse data fatigue level classifier model through an initial first pulse data training classifier, wherein first pulse data includes a first fatigue level label; predicting a second fatigue level label corresponding to newly collected second pulse data according to the pulse data fatigue level classifier so as to obtain the second fatigue level label; determining a fatigue level corresponding to the second fatigue level label according to the second fatigue level label. The fatigue level analysis method and device based on pulse characteristics can be carried out by a user to judge and measure the fatigue level quickly and conveniently; therefore, fatigue level measuring accuracy is improved, and a portable fatigue level measurer is brought for users.

Description

technical field [0001] The embodiments of the present invention relate to the field of medical technology, in particular to a fatigue degree analysis method and device based on pulse characteristics. Background technique [0002] In the prior art, since fatigue detection has the characteristics of many influencing factors and difficult definition, it becomes difficult to detect and judge fatigue in real time. [0003] At present, there are mainly two types of fatigue assessment methods: subjective assessment and objective assessment. Among them, the subjective evaluation method is carried out in the form of questionnaires, which is greatly affected by subjective factors; the objective evaluation method is to analyze work performance and physiological signals with the help of instruments and equipment. [0004] On the one hand, since the detection and analysis of fatigue usually requires professional fatigue detection equipment, the operation is complicated and the cost is h...
