Abstract
A display with the function of vision protection comprises a range sensor, a conventional display, wherein a single-chip computer in the conventional display could obtain the distance from the eyes to the screen of the display by the range sensor. When the distance exceeds the conventional distance, an alarm is produced in to remind the user to keep the safe distance, achieving the goal of vision protection. The utility model provides a display with vision protection, which could automatically remind people who use computers, especially pupils to protect vision, thereby resolving the difficult problem which generally exists in the current pupils and has the advantages of siplicity and utility.
Description
Technical field
The utility model 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.
The utility model content
In view of above-mentioned, the utility model 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 utlity model has following substantive distinguishing features and advantage:
The display that the utility model provides with eyesight protection function; 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 utlity model has eyesight protection function.
Fig. 2 is the circuit diagram that the utlity model has the typical specific embodiment of display of eyesight protection function.
Embodiment
Consult Fig. 1, the display that the utlity model has eyesight protection function 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:
Conventional display 2 is connected with distance measuring sensor 1 by its single-chip microcomputer mouth line; obtain the distance of people's eye by distance measuring sensor from indicator screen; when this distance surpass conventional apart from the time just give a warning, keep at a distance to remind people with computer, reach the purpose of vision protection.
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, the display with eyesight protection function according to claim 1, it is characterized in that: this distance measuring sensor is a ultrasonic sensor.
3, the display with eyesight protection function according to claim 1, it is characterized in that: this distance measuring sensor is an infrared ray sensor.
