Intelligent mental analysis and evaluation method and system based on human body characteristic data

Abstract

The invention provides an intelligent mental analysis and evaluation method based on human body characteristic data. The method comprises the following steps: acquiring an acquired human body electrocardiosignal, and calculating to obtain a respiratory fundamental frequency and an instantaneous heart rate power spectrum based on the human body electrocardiosignal; combining the obtained breathing fundamental frequency and the instantaneous heart rate power spectrum, calculating mental system characteristic parameters based on a floating frequency band method, and performing heart rate variability analysis on the mental system characteristic parameters; according to normal values corresponding to different age groups of the SDNN, calculating a short-term mental index; obtaining a periodic mental state score through data mining; according to the periodic mental state score, matching the human health data with a corresponding score according to a preset rule; and generating personalized evaluation and interpretation through the score. The invention further provides an intelligent mental analysis and evaluation system based on the human body characteristic data. According to the method and the system provided by the invention, the mental state can be evaluated more comprehensively and accurately through a data mining algorithm and an intelligent mode.

Description

technical field [0001] The invention relates to the technical field of mental evaluation, in particular to an intelligent mental analysis and evaluation method and system based on human body characteristic data. Background technique [0002] The progress and development of society has brought invisible pressure to people, resulting in personal physical and mental harm. Physical problems are easy to perceive; mental problems will only appear after long-term accumulation, and it takes a long time of comparative observation to find the difference. Mental problems accumulated over a long period of time may lead to a series of physical and psychological diseases, affecting physical and mental health. [0003] Traditional mental analysis mainly uses psychological tests to obtain mental states. This method will be affected by the state of the individual during the test, language expression ability, etc. In the prior art, psychoanalysis and evaluation based on the specificity of h...

However, a single heart rate variability signal is unstable, requiring the subject to maintain a relatively stable state for testing, and can only evaluate the mental state of the current time period. The results of such a test will have a large discrepancy with t
