Detailed description of the invention
As shown in Figure 1-2, a kind of computer vision protection display screen,
Comprise display screen body 1, described display screen body be provided with facial collector 2 and light intensity inductor 3 just above, described inDisplay screen body inside is provided with single-chip microcomputer, and the signal output part of described facial collector 2 and light intensity inductor 3 is connected to described monolithicThe signal input part of machine;
The signal input part of described single-chip microcomputer is also connected with electronic clock timing module;
The signal output part of described single-chip microcomputer is connected with sound prompt device;
The signal output part of described single-chip microcomputer is connected with screen intensity adjustment module;
The signal output part of described single-chip microcomputer is connected with light prompt device 4.
Further, between described facial collector and described single-chip microcomputer, be also connected TL852 sonar ranging receiving chip andLMV358 operational amplifier.
Further, described sound prompt device is loudspeaker or buzzer.
Further, described display screen is also provided with sound switch key 5, light prompt on & off switch 6 and power switch with itKey 7.
Further, described display screen is also provided with parameter increase key 8 with it, parameter reduces key 9, time setting key 10 andTime setting key 11.
When use, this device has been set the distance safety value of what a vision protection, utilizes hyperacoustic feedback signal,Measure the distance between eyes and screen, the distance signal of measuring exports single-chip microcomputer to, if be less than vision protection depending on thing distanceDistance safety value, single-chip microcomputer is to sound prompt device and output signal light suggestion device 4, the auditory tone cues dress of this deviceWhen having put signal light suggestion device 4 and will sound the alarm, light prompt device 4 flashes and reminds, if look object distanceFrom the safety value greater than or equal to vision protection, single-chip microcomputer is not defeated to sound prompt device and output signal light suggestion device 4Go out signal, this device does not give the alarm, and while prompting in the time that this device sends warning or light prompt, user must entangleThe just sitting posture of oneself, what make oneself looks thing distance higher than setting value, to reach the object of vision protection.
Facts have proved, 500 luxs are best study light intensities, and it is strong that the light intensity inductor of this device has light
Degree measuring ability, light intensity inductor is in real time to single-chip microcomputer output light intensity signal, if residing of userPractise environment
Light intensity is less than 300 luxs or during higher than 800 lux, single-chip microcomputer can be defeated to screen intensity adjustment moduleGo out signal, thereby this device will be sent out the object that can automatic adjusting screen brightness reaches vision protection.
This device can also be provided with electronic clock countdown module, and user is using certain hour (as 1 hour)
After, single-chip microcomputer can be to sound prompt device output signal, this device will send alerting signal remind user byIn time, has a rest, and alleviates visual fatigue, to reach the object of vision protection.
In order to facilitate the distance between this device Measurement accuracy user's eyes and books, simultaneously in order further to reach
The effect of reminding, improves warning that this device sends or the sound of light, excellent between facial collector and single-chip microcomputerChoosing connects
Be connected to TL852 sonar ranging receiving chip and LMV358 operational amplifier (not shown).
As further improvement of the utility model, user can arrange guarantor within the specific limits according to the demand of oneself
Protect safe distance and the service time of eyesight, the display screen of this device can also be provided with parameter with it increases key89, parameter reduces key 9, time setting key 10 and the such user of time setting key 11 and can press time setting key 10, thenIncrease key 8 or parameter and reduce key 9 according to the parameter of need to adjusting of oneself, realize the autonomous setting function of service time.
Further, this device can be the distance of pre-set vision protection while keeping correct sitting posture according to user
Safety value; Also can be the sitting posture that user adjusts oneself, ensure that sitting posture is autonomous according to the situation of oneself after correctSet protection
The distance safety value of eyesight, user presses time setting key 11, can increase key and parameter reduces by adjustingKey 9
Set the distance safety value of vision protection. If being less than the visual range of correct sitting posture, hyperacoustic range finding (protectsProtect eyesight
Apart from safety value), the sound prompt device light prompt device of this device will sound the alarm or lightCarry out
Remind, if hyperacoustic range finding greater than or equal to the visual range of correct sitting posture, this device does not give the alarmSound or light,
Report to the police or light while reminding when this device sends, user must correct the sitting posture of oneself, makes the order of oneselfThe apparent distance is high
In or equal setting value, to reach the object of vision protection.
