Technical Field
The invention relates to the technical field of sitting posture correction, in particular to a sitting posture detection and early warning method and a manufacturing method.
Background
The existing teenagers or workers sit in front of the workbench for a long time, and have no auxiliary equipment in sitting posture, so that the people are difficult to keep correct posture all the time; existing sitting posture aids are typically desktop posture correctors that are fixed to a desktop; the corrector is clamped and fixed on a desktop through a clamping device, and then a chin is supported; although the corrector is simple in structure and convenient to install, the corrector occupies a larger space of a desktop during working, shields a part of sight in front and is inconvenient to use.
Disclosure of Invention
The invention aims to provide a sitting posture detection and early warning method and a manufacturing method thereof aiming at the defects and the shortages in the prior art.
In order to realize the purpose, the invention adopts the technical scheme that:
the invention relates to a sitting posture detection and early warning method, which comprises the following steps:
a. at least three distance sensors are arranged at the position of the chair facing the back of the human body along the height direction;
b. the sensors with different heights acquire the distance D between the distance sensor and the human body at the corresponding height;
c. the data collected by the distance sensor is transmitted to an integrated circuit chip for calculation; the difference between the measured values of two adjacent sensors is Delta D; the distance between two adjacent distance sensors is delta L; calculating a tangent tan theta by using the ratio of delta D to delta L;
d. the program compares the calculated tan theta with a threshold value and initiates an alarm to alert the user if any one tan theta is outside the threshold range.
Further, the alarm mode may be a buzzer or a vibrator.
Further, the distance sensor makes a measurement every 100 milliseconds.
Further, the number of the distance sensors is three; the distance sensors are arranged at equal intervals.
Further, each distance sensor is capable of adjusting a height relative to the chair.
Further, three distance sensors are used to measure three positions of the waist, chest and neck of the human body, respectively.
Compared with the prior art, the invention has the beneficial effects that:
1) Obtaining tan theta by the ratio of the difference value of the back distances measured by two adjacent distance sensors to the distance between two adjacent distance sensors to the distance delta L; more than three distance sensors form multi-point monitoring, and more than two triangles can be formed; the influence of the front and back positions of a person sitting on the chair can be eliminated by directly measuring the angle change through a differential measurement method, namely the measurement result cannot be influenced when the person sits at the front end of the chair or sits at the back end of the chair;
2) The back measurement mode is adopted, the desktop space cannot be occupied, the sight cannot be influenced, and the use is more convenient.

Detailed Description
The present invention will now be described in detail with reference to specific examples, which are provided for illustration only and are not intended to be limiting.
As shown in fig. 1, in order to achieve the above purpose, the technical solution adopted by the present invention is:
a. three distance sensors are arranged at the position of the chair facing the back of the human body along the height direction; in addition, for convenient calculation, the distance sensors are arranged at equal intervals, and the distance between every two adjacent distance sensors is delta L;
b. the sensors with different heights acquire the distance D between the distance sensor and the human body at the corresponding height; adjusting the three distance sensors to three positions respectively used for measuring the waist, the chest and the neck of the human body;
c. the distance sensor takes a measurement every 100 milliseconds; data collected by the distance sensor is transmitted to the integrated circuit chip for calculation; the difference between the measured values of two adjacent sensors is Delta D; the measured distance of the neck is D1, the measured distance of the chest is D2, and the measured distance of the waist is D3; Δ D1 is equal to D1-D2; Δ D2 is equal to D2-D3; the distance between two adjacent distance sensors is delta L; calculating a tangent value tan theta 1 by using the ratio of the delta D1 to the delta L; calculating a tangent tan theta 2 by the ratio of delta D2 to delta L;
d. through comparing tan theta 1 and tan theta 2 with the threshold value set by a program, if any one tan theta exceeds the threshold value range, a buzzer or a vibrator sends out a signal to remind a user.
Compared with the prior art, the invention has the beneficial effects that:
1) Obtaining tan theta by the ratio of the difference value of the back distances measured by two adjacent distance sensors to the distance between two adjacent distance sensors to be delta L; more than three distance sensors form multi-point monitoring, and more than two triangles can be formed; the influence of the front and rear positions of a person sitting on the chair can be eliminated by directly measuring the angle change through a differential measurement method, namely the measurement result cannot be influenced when the person sits at the front end of the chair or sits at the rear end of the chair;
2) The back measurement mode is adopted, the desktop space cannot be occupied, the sight cannot be influenced, and the use is more convenient.
The foregoing is for the purpose of illustrating the invention only and various simple changes and modifications within the spirit of the invention made by those skilled in the art should fall within the scope of the invention.
