Bad sitting posture monitoring method based on TOF sensor

Abstract

The invention discloses a bad sitting posture monitoring method based on a TOF sensor, and the method is characterized in that the method comprises the steps: 1, enabling the TOF sensor to be installed at the edge of a desk close to a reader-writer, correcting the position of the TOF sensor to be downward, enabling the TOF sensor to measure and output the height difference N-S between a desktop and a seat surface, and enabling the reader-writer to adjust the height difference N-S between the seat surface, wherein the numerical range of NS is 22-33cm; 2, correcting the position of the TOF sensor in the upward measurement direction; adjusting the detection angle theta of the TOF sensor, and adding a fist distance between the TOF sensor and the TOF sensor; 3, the TOF sensor collects the distance X from the jaw of the reader and writer to the desktop in the sitting posture state; 4, a microprocessor analyzes that the detection value X is smaller than the sitting posture reference thresholdvalue X1, an output assembly communicated with the microprocessor sends out a first alarm signal, the TOF sensor is applied to detect the distance between the sensor and the jaw, whether the sittingposture of the reader-writer is correct or not is judged by comparing the threshold value in the database, and an alarm is sent out to remind the reader and writer; diseases caused by bad sitting postures can be improved, data are collected to establish a sitting posture big data model, and reasonable suggestions are given.

Description

technical field [0001] The invention relates to the field of behavior recognition, more specifically, it relates to a method for monitoring bad sitting posture based on a TOF sensor. Background technique [0002] In daily work and study, the sitting posture is the posture that lasts the longest. Compared with other postures, the sitting posture consumes less energy, making people less prone to fatigue and convenient for office and study, but maintaining an improper sitting posture for a long time will bring serious harm to human health. According to the survey, improper sitting posture keeps the spine in a flexed position or certain specific positions for a long time, and the pressure in the intervertebral disc of the spine increases. . [0003] At present, there are more than 400 million myopia patients in our country, and the myopia rate among teenagers continues to increase, largely because they do not pay attention to such problems, and the pressure of schoolwork and s...

[0004] What's more serious is that poor sitting posture can easily lead to myopia in young people. At present, there are more than 400 million myopic patients in my country, and the myopia rate among young people is constantly increasing. What's more serious is that the harm of myopia is irreversible, and high myopia is also easy to cause All kinds of eye diseases, even affect the normal life
