Embodiment Construction

[0012] This specific implementation mode adopts following technical scheme: its prevention and control method is:

[0013] Step 1: Connect the distance detection device to the head. The distance sensor, tilt sensor, processor and alarm are installed inside the distance detection device; at the same time, the output end of the processor is equipped with a connector, which is connected by a wire There is a display screen, and a reflective sheet is installed on the display screen;

[0014] Step 2: Turn on the device, set the data range according to the data displayed on the display, place the display on the desktop,

[0015] Step 3: Detect sitting posture: the distance data detected by the distance sensor is transmitted to the processor, and the processor processes the data and transmits it to the display screen. In the state, the tilt sensor transmits the data to the processor, the processor transmits the data to the display screen, and the alarm sounds at the same time;

Abstract

The invention discloses a nearsightedness-preventing posture prevention and control method for students and relates to the technical field of student tools. The prevention and control method comprises the steps that firstly, a distance detection device is arranged on the head in a sleeving mode; secondly, the device is turned on, a data range is set according to data displayed on a display screen, and the display screen is placed on a table top; thirdly, a sitting posture is detected; fourthly, data is stored, when a distance sensor and an inclination sensor transmit the data to a processor, the processor stores the data and uploads the data to an upper computer, and the upper computer carries out data integration according to the uploaded data; fifthly, a scheme is made, sitting posture correction is carried out according to the integrated data, the reading scheme is made according to the data, the sitting posture is changed, and nearsightedness-preventing posture prevention and control are achieved. By means of the method, quick prevention and control can be achieved, real-time data detection, display and uploading can be carried out, and integration and scheme making can be carried out according to the data.

Description

technical field [0001] The invention relates to the technical field of student appliances, in particular to a method for preventing and controlling postures used by students to prevent myopia. Background technique [0002] In the relaxed state of accommodation, parallel rays of light are focused in front of the retina after passing through the refractive system of the eyeball, which is called myopia. Myopia is also called short-sightedness, because this kind of eye can only see near but not far. When this kind of eye is at rest, the parallel light from infinity is refracted by the refractive system of the eye, and then gathers into a focal point in front of the retina, forming an unclear image on the retina, and the distance vision is obviously reduced, but the near vision Still normal. [0003] Existing students still can't meet the use requirements in the prevention and control of the anti-myopia posture, resulting in vision loss, and the operation is complicated and tim...
