Problems solved by technology

[0004] As teenagers themselves, there is no clear standard for judging whether their sitting posture is accurate. In daily study, it is also difficult for them to find out whether their sitting posture is standard, and classroom teachers or other guardians cannot supervise and guide a certain teenager for a long time. student sitting posture
[0005] Therefore, there is a lack of a device on the market that can be used to monitor the sitting posture of teenagers and inform the guardians or classroom teachers of the monitoring results, so that the guardians or classroom teachers can effectively remind teenagers with wrong sitting postures based on the test results and help them correct their mistakes sitting posture

Embodiment 1

[0047] Embodiment 1, myopia prevention and control device, with reference to figure 1 , figure 2 with image 3 , including a housing, the housing includes a base plate 2, a slant plate 1 is fixed and inclined on the base plate 2, one end of the slant plate 1 is connected to the base plate 2 through a curved plate 3, and the slant plate 1, the base plate 2 and the curved plate 3 are connected in turn ;

[0048] The bottom plate 2 is used to be placed on the desktop, and the inclined plate 1 and the bottom plate 2 are arranged obliquely, so that one end of the inclined plate 1 is directly connected to the bottom plate 2, and the other end of the inclined plate 1 is connected to the bottom plate 2 through a curved plate 3, and the curved plate 3 is connected to the bottom plate 2. The outer protrusion; the distance sensor 4 is installed on the curved panel 3, and the distance sensor 4 can be a TOF sensor. The detection light wave sent by the distance sensor 4 itself will form ...

Embodiment 2

[0080] Embodiment 2, a kind of detection method based on embodiment 1 myopia prevention and control device, step comprises as follows:

[0081] (a) Set the normal threshold of the sitting posture feature information and store it in the control module. This threshold input can be set to a threshold of a specific height by default in the factory, or it can be input by the teenager through the button on the outside of the housing during actual use. height, a suitable threshold is calculated by the microprocessor according to the height;

[0082] (b) After the threshold is selected, place the case on the table, the bottom plate 2 of the case is attached to the table, the distance sensor 4 faces the user, and the case is placed at 40cm from the edge of the table, keeping 6cm between the user and the edge of the table to obtain the current user's sitting posture feature information, that is, the actual distance from the user's chin to the distance sensor 4 at this moment, and the su...

Embodiment 3

[0087] Embodiment 3, its difference with embodiment 1 is that, with reference to Image 6 The distance sensor 4 is rotatably connected to the curved panel 3 through the rotating shaft 51, and a damping ring 52 is installed between the rotating shaft 51 and the distance sensor 4. The frictional resistance of the damping ring 52 enables the distance sensor 4 to be positioned at a rotated angle.

[0088] The curved panel 3 is provided with 3 rotating stations for the distance sensor 4, respectively indicating that the projection angles are 35 degrees, 40 degrees and 50 degrees;

[0089] If the height is below 130cm, the projection angle is 35 degrees;

[0090] If the height is between 130cm-165cm, the projection angle is 40 degrees;

[0091] If the height is above 165cm, the projection angle is 55 degrees;

[0092] This design is to further increase the accuracy of sitting posture detection.

Abstract

The invention discloses a myopia prevention and control device and a detection method. According to the technical scheme, the myopia prevention and control device is characterized in that the myopia prevention and control device comprises a shell and a distance sensor installed on the shell, wherein a projection included angle is formed between the distance sensor and the horizontal plane, and the angle range of the projection included angle is 29-60 degrees; a control module used for receiving a signal of the distance sensor, comparing the signal with a threshold value and outputting a processing signal of a standard sitting posture or a non-standard sitting posture according to a comparison result. The detection method based on the myopia prevention and control device comprises the following steps: (a) setting a normal threshold value of sitting posture characteristic information, and storing the normal threshold value to the control module; (b) placing the shell on a table top, the distance sensor facing a user, and obtaining sitting posture feature information of the current user; and (c) comparing the current sitting posture characteristic information with a normal threshold range, transmitting the current sitting posture characteristic information to an external terminal through a communication module, and transmitting a detection result to a teacher or a guardian by detecting the sitting posture of the teenager, so that the purpose of reminding and monitoring the sitting posture of the teenager by the teacher or the guardian is achieved.

Description

technical field [0001] The invention relates to the field of myopia prevention and control, more specifically, it relates to a myopia prevention and control device and a detection method. Background technique [0002] At present, there are more than 400 million myopia patients in our country, and the myopia rate among teenagers continues to increase. Among them, the pressure of schoolwork and study makes teenagers have to use their eyes for a long time. [0003] For teenagers, most of their eye time is consumed in class, and wrong sitting posture will lead to accelerated eye fatigue for teenagers. For example, reading materials too close to the desktop in class will make teenagers prematurely Put on the disease of myopia. What's more, the harm of myopia is irreversible, and high myopia can easily cause various eye diseases and even affect normal life. [0004] As teenagers themselves, there is no clear standard for judging whether their sitting posture is accurate. In dail...
