Problems solved by technology

The advantage of this type of method is that the method is mature and the detection is simple, but the detection accuracy is poor.
The optocoupler switch in the two-dimensional (2D) movement is used to sense whether the human body is sitting, which cannot reflect the differences between different individuals

Embodiment Construction

[0029]Figures 1 and 2 show the driving circuit of the walking motor of the massage movement of the original massage chair and the added detection circuit (indicated by a dotted line in the figure). The detection circuit is arranged in the driving circuit of the walking motor of the massager core. The detection circuit is provided with sampling resistor R5, current limiting resistor R6, voltage regulator diode D3, filter capacitors C1 and C2; sampling resistor R5, voltage regulator diode D3, filter capacitors C1 and C2 are connected in parallel; parallel sampling resistor R5, filter capacitor C1 and One end of C2 is connected to the gate of the field effect transistor Q1 in the original driving circuit of the walking motor, and the other end of the parallel connection sampling resistor R5, filter capacitors C1 and C2 is the power ground. One end of the current-limiting resistor R6 is connected to the gate of the field effect transistor Q1 of the original walking motor drive cir...

Abstract

The invention relates to a detecting method for human back contours, which provides a simple detection device with low cost and low requirement for device reliability. The back contours detecting method adopted in the invention is provided with a massager core with functions of back massage and walking. Human back data collecting: the walking motor of the massage core is started up; the massage core walks up and down on human back, in the process of walking, a detecting circuit collects data of each sampling point; a sampling value y in each sampling point is converted by an A / D transfer circuit in microprocessor and stored in the microprocessor to form a sampling data array y0, y1...ym; back contours fitting: after the sampling data y0,y1...ym is obtained, calculation is carried out by the microprocessor based on calculation software of mathematic models; the software is pre programmed and stored in the microprocessor; therefore the fitted human back contours can be drew and displayed through a displayer.

Description

technical field [0001] The invention relates to a method for detecting the curve of the back of a human body, in particular to a method for detecting the curve of the back of a human body by using a massage machine core with functions of back massage and walking. Background technique [0002] When the back of the human body is leaning on the chair, due to the support of the back of the chair, an "S" shape appears in the massage area, reflecting the shoulders, back, waist, buttocks and other parts of the human body, and people feel the strength of the massage in these parts There are differences, for example, the back massage should be more powerful, while the waist should be less powerful. After accurately detecting different parts of the human body, the massage intensity of these key parts can be controlled through the expansion and contraction of the walking movement of the massager, so as to achieve the purpose of improving massage comfort, and also for the future dev...
