Abstract

The invention discloses a sitting correction desk lamp comprising a desk lamp body, an infrared transmitter-receiver, a single-chip microcomputer, an LED dot matrix, a voice alarm and a direct current supply. The infrared transmitter-receiver and the LED dot matrix are located on the head of the desk lamp body. The single-chip microcomputer, the buttons, the direct current supply, a switch and the voice alarm are arranged on a base of the desk lamp body. The infrared transmitter-receiver can receive reflected signals from the human head; if a sitting posture is improper, the infrared transmitter-receiver detects no reflected signals and sends out voice alarming, and the LED dot matrix flashes to remind a user of adjusting the sitting posture. The sitting correction desk lamp has the advantages of simple structure, low cost, practicality and good service effect.

Description

A kind of sitting posture correcting desk lamp

Technical field

The present invention relates to technical field, is a kind of sitting posture correcting desk lamp specifically.

Background technology

In daily life, desk lamp be study and bend over one's desk working in the small household appliances often used, but wrong sitting posture easily causes fatigue, also can make visual impairment, more serious words also can cause child's the deformity of spinal column, are the problems that the head of a family worries very much.Although be also the desk lamp of some so-called correcting sitting postures on the market, price is more expensive on the one hand, uses in addition and is not very convenient.

Summary of the invention

The objective of the invention is, for above-mentioned deficiency of the prior art, in order to solve the problem existed in actual life, provides a kind of sitting posture correcting desk lamp.

The objective of the invention is to be achieved through the following technical solutions:

A kind of sitting posture correcting desk lamp, comprise desk lamp, infrared emission receives pipe, single-chip microcomputer, LED dot matrix (light emitting diode by one group of high brightness forms), phonetic alarm, switch and dc source, described infrared emission reception is positioned at the lamp holder position of desk lamp to pipe and LED dot matrix, single-chip microcomputer, button, power supply, switch and phonetic alarm are arranged at the base position of desk lamp, described infrared emission receives and pipe is detected to user's sitting posture did not produce at that time data-signal and send to described single-chip microcomputer to be processed, single-chip microcomputer sends alarm signal to phonetic alarm, send flash signal to the LED dot matrix simultaneously, infrared emission receives pipe, single-chip microcomputer, LED dot matrix and phonetic alarm adopt DC power supply.Infrared biography emission receives can be by receiving the reflected signal of human body head to pipe, judge whether head is in correct position, if head position descends, can depart from infrared biography emission and receive the position to pipe, infrared biography emission receives the signal that pipe be can't detect to reflection, will carry out audio alert, and makes the flicker of LED dot matrix, to remind the user to adjust sitting posture, reached the purpose of correcting sitting posture.

Single-chip microcomputer has used low-power consumption, high performance 51 series monolithics, except input signal is processed and signal feedback output, two buttons also are set steering wheel is adjusted, to reach, regulate the purpose of infrared biography emission to pipe aligning user head correct position, convenient, flexible.This desk lamp also comprises steering wheel and adjusts button, described adjustment button has two, be respectively and adjust upward button and adjust button downwards, when single-chip microcomputer has detected button and has pressed, at first be judged as still regulating key upwards of downward regulating key, then export different pwm signals to steering wheel, make steering wheel rotate, thereby drive the infrared emission reception linked together with steering wheel, the pipe transmitting site is offset up and down, to aim at user's head correct position.

Described power supply is charging accumulator.After charge in batteries, can normally use for desk lamp, when electric weight is not enough, can be to charge in batteries.Switch is for the opening and closing of desk lamp.

Concrete occupation mode is, infrared emission is received to the side that pipe is arranged on to the LED dot matrix part of desk lamp, and adjust the upper-lower position to pipe by with infrared emission, receiving the steering wheel that pipe is arranged on to one, to aim at the position of user's head, corresponding button and alarm module are installed on the base of platform.

The present invention has following outstanding beneficial effect: infrared emission receives being detected human head location, and the accurate performance of comparison high detection is arranged, and has advantages of that simple in structure, Cheap and practical and result of use are good.

The accompanying drawing explanation

Fig. 1 is sitting posture correcting desk lamp circuit theory schematic diagram of the present invention;

Fig. 2 is the structural representation of sitting posture correcting desk lamp of the present invention.

The specific embodiment

Below in conjunction with drawings and Examples, the invention will be further described:

Referring to Fig. 1, a kind of sitting posture correcting desk lamp, comprise desk lamp, infrared emission receives managing 1, single-chip microcomputer 3, LED dot matrix 4, phonetic alarm 5, switch 8, charging accumulator 6, steering wheel 2 and adjustment button 7, infrared emission receives managing 1, steering wheel 2 and LED dot matrix 4 are positioned at the lamp holder position of desk lamp, single-chip microcomputer 3, charging accumulator 6, switch 8, adjust the base position that button 7 and phonetic alarm 5 are arranged at desk lamp, infrared emission receives and user's sitting posture to be detected and do not produce at that time data-signal and send to single-chip microcomputer 3 to be processed managing 1, single-chip microcomputer 3 sends alarm signal to phonetic alarm 5, send flash signal to LED dot matrix 4 simultaneously, infrared emission receives managing 1, single-chip microcomputer 3, LED dot matrix 4 and phonetic alarm 5 adopt charging accumulator 6 power supplies, adjusting button 7 drives the infrared emission reception to move up and down managing 1 by single-chip microcomputer 3 control steering wheels 2.

Infrared emission receives and is mounted to an integral body to managing 1 with steering wheel 2, and the rotation of steering wheel 2 drives infrared emission and receives managing 1 up-down adjustment.Adjust button 7 two buttons are arranged, be respectively and adjust upward button and adjust button downwards, when single-chip microcomputer 3 has detected button and has pressed, at first be judged as still regulating key upwards of downward regulating key, then export different pwm signals to steering wheel 2, make steering wheel 2 rotate, be offset up and down managing 1 transmitting site thereby drive the infrared emission reception linked together with steering wheel 2, to aim at user's head correct position.Adopt STC89C51 in single-chip microcomputer 3(the present embodiment) be the control core of whole desk lamp, for receiving and process infrared emission, receive managing 1 signal of sending here, under normal circumstances, make LED dot matrix 4(be formed by the light emitting diode of one group of high brightness) normally luminous, when the improper signal of sitting posture being detected, start in audio alert 5(the present embodiment and adopt YS07) and the flicker of LED dot matrix 4.In actual product, by steering wheel 2, infrared emission receive to manage 1 and LED dot matrix 4 do as a whole, lamp holder as desk lamp, single-chip microcomputer 3, button 7, charging accumulator 6, switch 8 and phonetic alarm 5 are made to the base of an integral body as desk lamp, both consider the actual functional capability of desk lamp, considered again aesthetic property.

Be more than preferred embodiment of the present invention, all changes of doing according to technical solution of the present invention, when the function produced does not exceed the scope of technical solution of the present invention, all belong to protection scope of the present invention.
