S120, decompression movement time and exercise intensity is set according to described force value, and judges whether the time of subject motion exceedes the decompression movement time of setting; If not, then step S130 is performed; Be then, perform step S140.
During concrete enforcement, exercise intensity is also judged by exercise heart rate, movement time can be set to 15-60 minute according to the pressure index of experimenter by the present invention, and exercise heart rate is 60-90%MHR, by arranging the pressure of suitable movement time and movement rhythm alleviation experimenter.
The R-R interval of S130, continuation detection experimenter, calculates the force value of experimenter, and judges whether described force value is greater than decompression thresholding; If so, then step S140 is performed; Otherwise perform step S120.If movement time does not arrive, but through decompression motion, the force value of experimenter has been greater than decompression thresholding, and also directly can carry out arrangement campaign, experimenter controls respiratory frequency as requested, until motion terminates.
S140, prompting experimenter carry out arrangement campaign, and carry out respiratory frequency guide, until motion terminates.After the movement time of decompression motion arrives, monitoring device just points out experimenter to carry out arrangement campaign, and the time of its motion is generally five minutes, and shows respiratory frequency guide, until motion terminates.
Refer to Figure 16, Figure 17, Figure 18, Figure 19, Figure 20, Figure 21, wherein, Figure 16 detects schematic diagram R-R interval, and Figure 17 is that the present invention's control pressurer system of releiving detects R-R interval spectrum diagram.Low frequency component in this frequency diagram reacts orthosympathetic activity, and high fdrequency component reacts parasympathetic activity.Figure 18 is the HRV spectrum diagram of experimenter under actual measurement pressure state, and the HRV frequency spectrum of people under pressure state is based on low frequency component as can be seen from Figure 18.Figure 19 is the HRV spectrum diagram of experimenter under actual measurement relaxation state, and the HRV frequency spectrum of people under pressure state is based on low frequency component as can be seen from Figure 19.Figure 20 is the HRV spectrum diagram before actual measurement subject motion.Figure 21 is the HRV spectrum diagram after actual measurement subject motion, contrasts with Figure 21, and after people's road-work, the frequency spectrum of HRV, high fdrequency component obviously rises, and reaches the object of decompression.
In sum, the present invention draws pressure index by the R-R interval detecting experimenter, judge whether to need motion decompression, then calculate corresponding motion index according to pressure index, when user carries out decompression campaign, detect R-R interval simultaneously, human body respiration and human activity signal, and show these parameters in real time, and simple decompression exercise program is provided, by controlling the exercise intensity of people, breath rhythm and movement time in motor process, reach the effect of pressure of releiving.
Simultaneously, Stress appraisal system of the present invention and control pressurer system of releiving, wearable and unpick and wash, can routine use, at hardware aspect, do miniaturization and power saving optimized design, allowed user can wear use under natural state, avoid the instrument of the heaviness of existing laboratory system and wire in heaps, its volume is little, is easy to carry, and dismantled and assembled being convenient to of system is cleaned.
Be understandable that, for those of ordinary skills, can be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, and all these change or replace the protection domain that all should belong to the claim appended by the present invention.
