Method for calculating metabolic rate in sleep process

Abstract

The invention relates to a method for calculating a metabolic rate in a sleep process. The method comprises the following steps: measuring the weight of a bed once every first preset time, identifying a steady state according to a measured value, identifying a start moment and an end moment of sleep according to the steady state, identifying an abnormal event and calculating a weight difference value generated during the abnormal event; obtaining a body weight absolute reduction value in the sleep period according to the measured values of the pressure sensor at the sleep starting moment and the sleep ending moment and the body weight difference value generated by the abnormal event; calculating the sleep metabolism rate by using the value of the absolute loss of body weight during sleep. According to the method, the absolute weight loss of the person sleeping on the bed is measured, the metabolic quantity is calculated according to the weight loss in the sleeping process, and due to the fact that weight measurement is more direct than heat measurement, the metabolic condition of the person can be reflected more truly; by introducing abnormal events, various interference factors influencing the body weight in the sleep process can be eliminated, and the body weight measurement is more accurate.

Description

technical field

[0001] The invention belongs to the technical field of monitoring metabolic rate during sleep, and relates to a calculation method for metabolic rate during sleep. Background technique

[0002] Metabolic rate represents the energy consumed by the body per unit time. In the prior art, the metabolic rate is generally calculated by calorie metabolism, but it is difficult to monitor the calorie, and can only be converted by other indicators, resulting in large errors in the calculation results.

[0003] Because people are consuming energy all the time, without drinking water or eating, their weight must be gradually decreasing. Therefore, the metabolic rate can also be calculated through the change of body weight, but the value of this weight change is very small, and the traditional weight Measurement methods cannot accurately monitor this reduced value, and people's metabolic rate will also fluctuate greatly due to different exercise amounts at different perio...
