Problems solved by technology

At present, the commonly used psychological stress assessment methods mainly include: homework method, projection method and scale method. These methods share the defects of being affected by the subject's subjective factors and cognitive level;
[0003] The 2010 Zhong Tianping master's degree thesis of Nanjing Medical University "Research on the Development and Application of Psychological Quality Assessment Training System" mentioned that HRV is used for psychological quality testing, but did not specify specific parameters and evaluation methods

Embodiment Construction

[0043] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0044] Such as figure 1 A multi-parameter psychological stress assessment method based on the analytic hierarchy process is shown, the key of which is to include the following steps:

[0045] S1: Obtain the HRV signal of the subject to be tested, perform frequency domain, time domain and nonlinear analysis on the HRV signal respectively, and obtain the parameter set G={G 1 ,G 2 ,G 3};

[0046] G 1 ={G 11 ,G 12} is the HRV signal frequency domain parameter set; G11 is the ratio of low frequency to high frequency LF / HF; G 12 is the score TP;

[0047] G 2 ={G 21 ,G 22 ,G 23} is the HRV signal time domain parameter set; G 21 is the standard deviation SDNN of normal sinus rate RR interval; G 22 In all RR intervals, the number of adjacent RR intervals with a difference greater than 50 ms accounts for the percentage of all RR intervals PNN50; G ...

Abstract

The invention discloses a multi-parameter mental stress assessment method based on an analytical hierarchy method and a device. The method obtains a parameter set of mental stress influential factors through analysis of a frequency domain, a time domain and non-linearity of HRV signals of a testee, and obtains mental stress assessment results of the testee by the analytical hierarchy method and a mental stress assessment model. The device collects electrocardiograph signals of the testee, analyzes and assesses the electrocardiograph signals by the multi-parameter mental stress assessment method based on the analytical hierarchy method, outputs an assessment report and transmits the assessment report outwards. The multi-parameter mental stress assessment method based on the analytical hierarchy method and the invention have the beneficial effect that (1) a mental stress state of the testee is monitored according to changes of HRV physiological parameters of the testee, so influences brought by subjective factors and different cognitive levels of the testees to monitoring results are effectively avoided; and (2) the daily mental stress state of the testee is effectively recorded and analyzed, and key data is stored to remind the testee of self-adjustment and taken for standby application of medical staffs.

Description

technical field [0001] The invention relates to the field of medical psychological pressure measurement and evaluation, in particular to a multi-parameter psychological pressure evaluation method and device based on analytic hierarchy process. Background technique [0002] In today's society, the various pressures that people face have a serious impact on people's mental health, and even lead to life-threatening. Mental stress has been defined by the World Health Organization as "the scourge of the Western world", and according to the International Labor Office, it has become "one of the most serious problems of our time, endangering not only the physical and mental health of individuals but also businesses and governments. harmful". At present, the commonly used psychological stress assessment methods mainly include: homework method, projection method and scale method. These methods share the defects of being affected by the subject's subjective factors and cognitive level...
