Human body back curve detection method and device, electric control system and massage chair

Abstract

The invention provides a human body back curve detection method and device, an electric control system and a massage chair. The method comprises the following steps: determining the positions of shoulders of a user by adjusting a massage machine core, and dividing the back of a human body into areas according to the positions of the shoulders, so as to distribute one or more collection points to each divided area; moving the massage machine core to each collection point to obtain a force value corresponding to the collection point; comparing the force value with a preset massage force reference value corresponding to the collection point, and adjusting an angle value of the massage machine core corresponding to the collection point; and according to the moving pulse number of the massage machine core corresponding to each acquisition point and a coordinate point formed by the angle value, fitting a reference curve for adjusting the massage manipulation and force of the massage machine core by adopting a least square method. The method is accurate in detection and low in cost, the reference curve which can be directly applied to massage strength and manipulation regulation and control can be obtained, and improvement of massage comfort and safety is facilitated.

Description

Technical field [0001] The present application relates to the technical field of massage, and in particular, there is a human back curve detection method, device, an electronically controlled system, a massage chair. Background technique [0002] People have tall fat, the massage chair should achieve intelligent adjustment according to the user's body shape in order to achieve the best massage effect. Therefore, how to intelligently check the user's back curve, is an important issue in the technical field of massage. [0003] At present, the detection method of the back curve of the user is mainly divided into two categories: simulation method and direct method. [0004] The simulation method is to determine the height of the user by detecting the shoulder position of the human body, and then simulates the sizes of the individual body through the general proportional relationship of the human body. The advantage of this type of method is that the method is mature, simple, but the...
