Abstract
The utility model relates to an appearance is reminded to student's myopia prevention is used for the appearance, is applicable to students in middle and primary schools. The utility model discloses a: supersound distance sensor, singlechip, supersound range sensing is connected with the microcontroller type end, and the singlechip output is connected with display module and voice module respectively. The utility model discloses a distance between supersound distance sensor perception health and desk reminds the student to hasten to adjust the position of sitting through vibration or music, makes to keep the normalized distance to leave between health and desk, and vibration or music promptly can the automatic shutdowns, and the eye fatigue is avoided from the angle that the science was used up to effective prevention myopia and bow -backed, prevents near -sighted protect your eyesight.
Description
Technical field
This utility model relates to a kind of myopia for student prompting instrument for instrument, it is adaptable to students in middle and primary schools.
Background technology
Have a lot for correcting the instrument of students in middle and primary schools' sitting posture and preventing students from nearsightedness in the market, but will there is respective deficiency, such as BABAKA, rely on the behavior of hard material constraint student, wearer's upper body is made to keep a posture stood up for a long time, health can produce feeling of fatigue, very uncomfortable, does not like wearing.
Utility model content
The purpose of this utility model is in that to provide a kind of student's health when loosening, it is possible to conscious correction incorrect sitting-pose, it is to avoid the myopia for student prompting instrument of student's deformity of spinal column and hypometropia.
Technical solution:
This utility model includes: ultrasonic distance sensor, single-chip microcomputer, and described ultrasonic Distance-sensing is connected with single-chip microcomputer input, and single-chip microcomputer outfan is connected with display module and voice module respectively.
Described single-chip microcomputer, display module and voice module are placed in housing, are provided with battery placing trough in housing, and housing is provided with display lamp, on and off switch, and described single-chip microcomputer, display lamp and on and off switch are connected with battery respectively.
This utility model is by the distance between ultrasonic distance sensor perception health and desk; undertaken reminding student to hasten to adjust sitting posture by vibration or music; make between health and desk, to keep normal distance; namely vibration or music can be automatically stopped; effectively pre-myopia prevention and hunchback; the angle used up from science avoids eyestrain, pre-myopia prevention protection vision.
