Abstract
The invention discloses a device for preventing shortsightedness. The device comprises a single-chip microcomputer controller, wherein an ultrasonic range finder is connected with the single-chip microcomputer controller through a conducting wire; a distance setting button is connected with the single-chip microcomputer controller through a conducting wire; the single-chip microcomputer controller is connected with a display and an audible alarm device through conducting wires. The device solves the problems that instruments for preventing nearsightedness are hardly found in the prior art, and eyesight correcting instruments are worn by people for correcting shortsightedness only after shortsightedness.
Description
Technical field
The invention belongs to preventing myopia technology, particularly relate to a kind of device of preventing myopia.
Background technology
Present child is owing to playing computer, mobile phone and increasing of doing one's assignment, the people of hypometropia gets more and more, because child is at object for appreciation computer, mobile phone or do not note sitting posture and the distance between eyes and object when doing one's assignment, cause one of hypometropia large reason, hypometropia can have a strong impact on the studying and living of people, therefore preventing myopia is extremely important, present preventing myopia mainly by wearing eye correction instrument to realize on eyes, mainly correction instead of prevention, and special eye correction instrument price, and be worn on eyes and can not do other things, very inconvenient.
Summary of the invention
The technical problem to be solved in the present invention: the device providing a kind of preventing myopia, to solve the instrument not having now special preventing myopia, can only adopt problems such as wearing eye correction instrument to correct after hypometropia.
Technical solution of the present invention:
A device for preventing myopia, it comprises singlechip controller, and ultrasonic range finder is connected with singlechip controller wire, and distance setting button is connected with singlechip controller wire, and singlechip controller is connected with display screen and audible alarm unit wire.
Described device adopts charged lithium cells to power.
Beneficial effect of the present invention:
The present invention adopts charged lithium cells to power, the present invention is placed on or be integrated on cap with it, the distance of the automatic testing human of ultrasonic range finder or human eye and object, when distance is less than setting value, singlechip controller is sounded warning, and prompting user notes eyes, not from object too close to, solve the instrument not having now special preventing myopia, problems such as wearing eye correction instrument to correct can only be adopted after hypometropia.
accompanying drawing illustrates:
Fig. 1 is structure of the present invention composition schematic diagram.
embodiment:
A kind of device of preventing myopia, it comprises singlechip controller, ultrasonic range finder is connected with singlechip controller wire, distance setting button is connected with singlechip controller wire, singlechip controller is connected with display screen and audible alarm unit wire, the Distance geometry current human of the main display setting in real time of display screen is from the actual range of target object, described device adopts charged lithium cells to power, whole device volume is little, device forms simple low price, be beneficial to very much and promote the use of, when for preventing myopia, preferably the present invention is arranged on cap, user is reminded to note by the distance of ultrasonic range finder and object.
