Abstract
Display with function of eyesight protection includes distance finding sensor, normal display. The single chip in the normal display obtains distance between eyes and display via distance finding sensor, when the distance exceeds normal distance, it alarms to prompt user keep distance to achieve purpose of protecting eyesight. The display with function of eyesight protection provided in the invention can alarm user using computer, especially minors, and problems of using computer for long time of minor can be resolved, it possesses characters of easy and utility.
Description
Technical field
The present invention relates to conventional computer monitor.
Background technology
Extensively exist a minor who makes the head of a family have a headache to cause the difficult problem of myopia for a long time with computer at present.Market in urgent need uses the display that simply has eyesight protection function flexibly to solve this problem.
Existing display is conventional computer monitor, does not have eyesight protection function.
Summary of the invention
In view of above-mentioned, the invention provides a kind of easy, practical display with eyesight protection function.
Have the display of eyesight protection function, it is characterized in that: comprise
Distance measuring sensor: be used to measure the distance of people's eye from indicator screen;
Conventional display: be connected to above-mentioned distance measuring sensor; be used for obtaining the distance of people's eye by distance measuring sensor from indicator screen by single-chip microcomputer in the conventional display; when this distance surpass conventional apart from the time just give a warning; to remind people to keep at a distance, reach the purpose of vision protection with computer.
Described distance measuring sensor can be the sensor that ultrasonic sensor, infrared ray sensor or other can measuring distances.
The present invention has following substantive distinguishing features and advantage:
Display with eyesight protection function provided by the invention; want vision protection in the time of can reminding people, especially minor with computer automatically with computer; solve a ubiquitous difficult problem that causes myopia for a long time with computer among the present minor, had simple, practical characteristics.
Description of drawings
Fig. 1 is the display electricity theory diagram that the present invention has eyesight protection function.
Fig. 2 is the circuit diagram that the present invention has the typical specific embodiment of display of eyesight protection function.
Embodiment
Consult Fig. 1, the present invention has the display of eyesight protection function and is made up of distance measuring sensor 1, conventional display 2.
Various functional circuit module described in Fig. 1 all belong to general and proven technique, and all can adopt multiple scheme to realize.Though the scheme that realizes can be ever-changing, its ultimate principle is the same:
Fig. 2 is a kind of typical examples of implementation.In this example, distance measuring sensor is that X1 adopts ultrasonic sensor; Conventional display is done representative by the single-chip microcomputer U1 in it (adopting 89C51).Structure and principle that it is detailed are as follows:
Single-chip microcomputer U1 sends the ultrasound wave drive signal by its mouthful line DRV on the one hand as central processing unit, so that ultrasonic sensor X1 sends ultrasound wave, starts timing simultaneously; The ultrasound wave that is sent will be returned ultrasonic reflections when running into people's head, received by ultrasonic sensor, and through after amplifier U1 (NE5532) amplification, detected by the mouth line REV of single-chip microcomputer U1, just represented people's head (eye) distance from screen between institute's timing this moment.Single-chip microcomputer is through after relatively, and if this distance is just sent prompting (as passing through pilot lamp or screen prompt) greater than conventional distance.
Claims (3)
1, has the display of eyesight protection function, it is characterized in that: comprise
Distance measuring sensor: be used to measure the distance of people's eye from indicator screen;
Conventional display: be connected to above-mentioned distance measuring sensor; be used for obtaining the distance of people's eye by distance measuring sensor from indicator screen by single-chip microcomputer in the conventional display; when this distance surpass conventional apart from the time just give a warning; to remind people to keep at a distance, reach the purpose of vision protection with computer.
2, according to claim 1 described display with eyesight protection function, it is characterized in that: this distance measuring sensor is a ultrasonic sensor.
3, according to claim 1 described display with eyesight protection function, it is characterized in that: this distance measuring sensor is an infrared ray sensor.
