S3 obtains respiratory rate f according to the respiratory curve, and the respiratory rate is 1/T；
S4, according to preset eupnea value, real-time judge respiratory state, when the crest value in the single breath time is in 95%-
Between 105% eupnea value, then it is judged as eupnea, if being higher than 105% eupnea value, is judged as deep breathing, if
Lower than 95% eupnea value, then it is judged as shallow breathing；
S5, eupnea number, deep breathing number and shallow breathing number, judge the state of human body in the unit of account time.
