Intelligent posture regulating sofa and control method thereof

Abstract

The invention relates to an intelligent posture regulating sofa and a control method thereof. The method comprises the following steps of (1) reading a pressure value P hip corresponding to a hip support surface and a pressure value Pi corresponding to a non-hip support surface; calculating a average pressure value pavg of the P hip and the Pi; (2) comparing the pavg and a minimum average pressurevalue pavg-min, wherein the pavg-min is greater than 15 but is smaller than 60; if the pavg is greater than the pavg-min, entering the step (3); if the pavg is smaller than or equal to the pavg-min,returning to the step (1); (3) calculating a standard pressure difference value p delta i according to the Pi and the pavg; comparing the p delta i with a triggering threshold value P valve i; if thep delta i is greater than the P valve i, and the receiving of an extreme position signal is not detected, entering the step (4); if the p delta i is smaller than the P value i, and the receiving of aninitial position signal is not detected, entering the step (5), wherein the P valve i is an artificial setting value; (4) enabling a servo motor to rotate at the rotating speed alpha*p delta i; driving a non-human-hip support surface to move in a direction of leaving far away from the human body; (5) enabling the servo motor to rotate at the rotating speed alpha*p delta i; driving the non-human-hip support surface to move in a direction of approaching to the human body; (6) returning to the step (1) for circulation. The intelligent posture regulating sofa solves the problem of nonuniform distribution of pressure of each part.

Description

technical field [0001] The invention relates to the field of intelligent sofas, in particular to an intelligent posture-adjusting sofa and a control method. Background technique [0002] At present, the posture-adjustable sofas on the market are all manually adjusted. The comfortable posture of the sofa needs to be adjusted repeatedly by the user. After the sofa posture is adjusted, it will always maintain the same posture unless it is adjusted again. The posture will become no longer comfortable. The user's repeated adjustment of the sofa posture will undoubtedly affect the rest experience, and many users cannot adjust the sofa to the best posture of the body through their own feelings due to personal reasons (such as drunkenness, local numbness, etc.). On the contrary, it is harmful to the body. Contents of the invention [0003] The purpose of the present invention is to provide an intelligent posture-adjusting sofa and its control method. The pressure sensor monitors ...

Problems solved by technology

[0003] The purpose of the present invention is to provide an intelligent posture-adjusting sofa and its control method. The pressure sensor monitors the user's action in real time, and when the user moves, the sofa is driven by a servo motor to cater to the user's action, which solves the problem of inaccurate manual posture adjustment and also solves the problem of inaccurate manual posture adjustment. Solved the problem that the sofa posture needs to be readjusted after the user action
