Mattress pressure comfortableness evaluation method

Abstract

The invention discloses a mattress pressure comfortableness evaluation method, which comprises the following steps of: (1) arranging a body pressure measuring instrument on a mattress, testing the body pressure distribution when the people sleep on the mattress, and obtaining body pressure distribution data; (2) performing mathematical treatment on the body pressure distribution data, and calculating and obtaining a maximum pressure, an average pressure, a maximum pressure gradient, an average pressure gradient, and a contact area; (3) giving out mattress comfortableness evaluation data after sleep experience is performed on the mattress by subjects; and (4) using a GA-Elman neural network and establishing a coupling model between body pressure distribution index data of the subjects and corresponding evaluation data, and outputting an evaluation result through the coupling model, the Ga-Elman neural network being to optimize initial network weights of an Elman neural network structure by using a genetic algorithm. The mattress pressure comfortableness evaluation method combines body pressure distribution indexes and human body evaluation data to evaluate the comfortableness of the mattress, thereby helping people to choose the mattress with better comfortableness and ensuring the people to enjoy a comfortable sleep.

Description

technical field [0001] The invention relates to a method for evaluating the pressure comfort of a mattress. Background technique [0002] Mattress is the necessary furniture for the human body to sleep, and its comfort greatly affects the quality of people's rest. A comfortable mattress can relax the muscles of the waist, back and buttocks well. In 1986, a survey by Addison et al. showed that 7% of American adults stated that their sleep problems were related to the comfort of their own mattresses. Comfort is a very complex system, which is affected by human physiological and psychological factors, so it is difficult to study. Despite extensive research, controversy remains. This controversy is not only manifested in the definition of methods, but also in the evaluation of various evaluation methods. It can be said that the various evaluation methods of comfort have their own advantages and disadvantages, and there is no uniform standard. Therefore, it is of great signif...

AI Technical Summary

Problems solved by technology

The existing method does not establish a quantitative model to evaluate the comfort of the mattress by using the body pressure distribution index, and the evaluation result is not very good; in addition, the existing method does not combine the subjective comfort evaluation data of the subjects , the comfort is evaluated only by the body pressure distribution index, and the reliability of the result is not high
