Sitting posture correction device and method

Abstract

The invention discloses a sitting posture correction device and method. A pressure sensor is embedded in the position, above a sitting part, of a wiring channel, and the wiring channel penetrates through a supporting part from the lower part of the sitting part to extend to the rear side of a backrest part; an ultrasonic sensor is arranged on the junction of the inner side of the upper end of thebackrest part and the wiring channel, and a microcontroller and an alarm are arranged on the junction of the outer side of the upper end of the backrest part and the wiring channel; the value of the pressure applied to the sitting part is obtained, and the pressure value is compared with a pressure threshold value to identify whether a human body is borne by the sitting part or not; after it is identified that the human body is borne by the sitting part, the ultrasonic sensor is awakened to obtain the spacing distance between the neck of the human body and the backrest part; when the spacing distance is larger than a given distance threshold value, the duration starts to be counted, and when the duration is larger than a given time threshold value, correction early warning is conducted; and when the spacing distance is smaller than the given distance threshold value, correction early warning is stopped. The problems, commonly existing in students, such as the poor posture of doing homework, hunchback and getting too close to books are corrected.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of seats, in particular to a device and method for correcting sitting posture. Background technique [0002] Sitting posture refers to the posture of the human body when sitting. The correct sitting posture should keep the upper body straight at all times. The human pelvis is in an upright state, and the shoulders, neck, and back are vertically in a straight line, while the wrong sitting posture is opposite. In learning, try to sit in the correct posture so that you can have good health and study well. Wrong sitting posture can lead to myopia and hunched back; wrong sitting posture can induce various diseases such as cervical spondylosis and lumbar spondylosis; Vertebrae, and lead to spinal deformation, scoliosis; wrong sitting posture will affect the child's bone development; bad sitting posture can cause inattention in learning; bad sitting posture can sometimes lead to weariness and ...

In learning, try to sit in the correct posture so that you can have good health and study well. Wrong sitting posture can lead to myopia and hunched back; wrong sitting posture can induce various diseases such as cervical spondylosis and lumbar spondylosis; Vertebrae, and lead to spinal deformation, scoliosis; wrong sitting posture will affect the child's bone development; bad sitting posture can cause inattention in learning; bad sitting posture can sometimes lead to weariness and depression; bad sitting posture can lead to easy fatigue; Sitting affects writing and academic performance

[0003] At present, due to the lack of supervision from teachers and parents in the process of learning at home, it is common for students to have improper posture in their study or homework. If it goes on for a long time, it is easy to cause hunchback, high and low shoulders, etc., and it is easy to have similar problems if they are too close to the book. , in the prior art, the general corrective measure is to install hardware on the desktop, which is likely to interfere with student learning and distract students from learning
