Abstract
The utility model discloses a sight protection device of connection on computer, including sensor input module, single -chip module, communication module and host module. Sensor input module connects single -chip module including the ultrasonic sensor who is used for detecting user's head and computer screen distance, the optical line sensors who is used for detecting ambient light intensity, sensor input module, and single -chip module passes through communication module and connects host module. , automatically adjust the screen intensity and have host module and two sets of alarm device of single -chip module to the distance of screen and ambient light's power through detecting computer user head. Synthesize time, distance, computer screen intensity and the peripheral luminance of people before the computer and device that the automatically regulated screen intensity can be reported to the police to prevent that the computer is to optical harm.
Description
Technical field
The utility model relates to a kind of vision protection device, especially a kind of vision protection device connected on computers.
Background technology
Current, the use of computer is very universal, and many people work long hours before computer, and owing to not noting regulating the brightness of computer screen and the distance with screen in time, time one slot mesh eyeball will feel tired, causes eye disease even.In current technical scheme, mainly detect the time of people before computer and distance and the scheme of reporting to the police, also do not have the time of a kind of comprehensive people before computer, distance, computer screen brightness and periphery brightness and the device that also can report to the police of adjusting screen brightness automatically.
Utility model content
The purpose of this utility model be to provide the time of a kind of comprehensive people before computer, distance, computer screen brightness and periphery brightness and adjusting screen brightness the device that can report to the police automatically, to prevent computer to the infringement of eyesight.
The utility model adopts following technical scheme:
A kind of vision protection device connected on computers; it is characterized in that; comprise sensor load module, one-chip computer module, communication module and host module; described sensor load module comprises ultrasonic sensor for detecting user's head and computer screen distance, for detecting the light sensor of ambient light intensity; sensor load module connects one-chip computer module, and one-chip computer module connects host module by communication module.
Preferably, described ultrasonic sensor is arranged on the surrounding of computer screen, and ultrasonic sensor determines the distance of user's head and computer screen for detecting it to the distance of user's head according to self-view.
Preferably, described communication module is connected by USB interface with host module.
Preferably, described one-chip computer module is provided with the reset key for manual reset.
Preferably, described one-chip computer module is also provided with sound light alarming circuit.
The Advantageous Effects adopting as above technical scheme to obtain is:
The utility model structure is simple, and by detecting the power of computer user head to the Distance geometry ambient light of screen, automatically adjusting screen brightness also has host module and one-chip computer module two to overlap warning device.The time of comprehensive people before computer, distance, computer screen brightness and periphery brightness and adjusting screen brightness the device that can report to the police automatically, to prevent computer to the infringement of eyesight.
Accompanying drawing explanation
Fig. 1 connects vision protection device block diagram on computers.
Embodiment
1 embodiment of the present utility model is described further by reference to the accompanying drawings:
Connect a vision protection device on computers, comprise sensor load module 1, communication module 2, one-chip computer module 3 and host module 4.Sensor load module comprises ultrasonic sensor for detecting user's head and computer screen distance, for detecting the light sensor of ambient light intensity, sensor load module connects one-chip computer module, and one-chip computer module connects host module by communication module.
Ultrasonic sensor is arranged on the surrounding of computer screen, and ultrasonic sensor determines the distance of user's head and computer screen for detecting it to the distance of user's head according to self-view.
Communication module is connected by USB interface with host module.The effect of this module is the communication between responsible one-chip computer module and host module, utilizes the USB interface of computer to realize, is provided the power supply of+5V simultaneously by USB interface to one-chip computer module and sensor load module.
One-chip computer module is provided with reset key for manual reset and sound light alarming circuit.The input analog amount of ultrasonic sensor and light sensor is converted to digital quantity by the analog to digital converter that single-chip microcomputer carries, and sends it to host module by communication module, carries out judging the work of rear control sound light alarming circuit on the other hand.
Host module utilizes communication module to the input digital quantity adjusting screen brightness automatically of the ultrasonic sensor receiving single-chip microcomputer and send and light sensor, sends chimes of doom and display alarm information; The information such as screen intensity are passed to one-chip computer module simultaneously.
In actual applications: host module 4 records the distance of head to screen that one-chip computer module 3 sends user, and judge whether user's head is less than 30mm (this numerical value can be regulated between 30-50mm by program) or user's whether continuous work before computer more than 30 minutes (this numerical value can be regulated between 30-50 minute by program) to the distance of screen, if meet one of above two conditions, host module 4 just sends chimes of doom and display alarm information.
Meanwhile, the information such as screen intensity also can be passed to one-chip computer module 3 by host module 4, and the digital quantity that can record according to ultrasonic sensor and light sensor to make one-chip computer module 3 and screen intensity judge separately, rear control sound light alarming circuit work.Host module and one-chip computer module two overlap warning device cooperating, timely reminding user, to prevent computer to the infringement of eyesight.
Certainly; more than illustrate and be only preferred embodiment of the present utility model; the utility model is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the guidance of this instructions; made all equivalently to substitute, obvious form of distortion, within the essential scope all dropping on this instructions, protection of the present utility model ought to be subject to.
