Feedback adjusting bed based on terahertz wave detection

Abstract

A feedback adjusting bed based on terahertz wave detection comprises a bed body, a terahertz wave radiating source, a terahertz wave detector, a mechanical moving device, a pressure detector and a control device; the mechanical moving device includes a plurality of mechanical micro units and may telescope independently perpendicular to the surface of the bed body; the pressure detector can detecta pressure change of the bed body surface and transmit a pressure change signal to the control device; when it is detected that a user starts to use the bed body or the sleep position of the user changes, the terahertz wave radiating source and the terahertz wave detector are triggered to operate, providing terahertz wave imaging for the bed body and the human body; the control device judges the position of a predetermined part of the human body relative to the bed body according to imaging conditions and adjusts telescoping quantities of the mechanical micro units in the corresponding region,such that the human body is given effective balanced supporting. The feedback adjusting bed based on terahertz wave detection has high comfort, and can shape the body, prevent spinal diseases and assist in treatment.

Description

Technical field [0001] The invention relates to a bed, in particular to a feedback regulating bed based on terahertz (THz) wave detection. Background technique [0002] The comfort of the bed directly affects the quality of sleep. If the bed is too soft, the human body’s hips and shoulders are more protruding, and the bed will deform; if the bed is too hard, the bed cannot change with the body curve, regardless of the bed Too soft or too hard, all parts of the body are not balanced and supported, the spine will be under varying degrees of pressure when lying in bed, and people’s comfortable rest and deep sleep are not used; at the same time, the human spine has 4 natural physiological curvatures : Cervical curvature, chest curvature, lumbar curvature and sacral curvature, of which the cervical curvature, lumbar curvature are convex forward, and the chest curvature and sacral curvature are concave backward. A bed that is too soft or too hard can not support the spine well, causin...

Problems solved by technology

However, the infrared detector detects according to the different intensities of infrared rays radiated from various parts of the human body. When sleeping, you will always wear clothes and quilts, and the infrared penetration performance is limited, which also seriously affects the accuracy of the detection signal

In addition, the pressure detection device can detect whether the sleeping posture of the human body has changed when it is relatively static, but it cannot accurately determine the position of each part of the human body.
