Description
Technical field
This utility model relates to a kind of vision protector, specifically is a kind of distance control vision protector, belongs to electronic technology field.
Background technology
Raising and progress of science and technology along with economic level; there has been increasing people to begin to understand information by the mode that electronics shows; and increasing people is arranged because various requirements of one's work; have to for a long time in the face of all kinds of electronic displays; this has brought very big harm with regard to the vision of giving people; if people do not note healthy being accustomed to eye; just can cause increasing people visual problems to occur; and some vision protector majorities that exist in the market only have single induction alarm function; remind the protection effect undesirable, can not effectively prevent the problem of people's excess eye-using.
Summary of the invention
At the problem that above-mentioned prior art exists, this utility model provides a kind of distance control vision protector, has voice reminder and visual prompts dual mode, effectively the distance of reminds people maintenance and display screen.
To achieve these goals; this utility model is achieved through the following technical solutions: a kind of distance control vision protector; comprise induction apparatus; Programmable Logic Controller; speech chip; speaker and power supply; Programmable Logic Controller comprises screen prompt system and time switch system; induction apparatus is connected by analog circuit with the signals collecting port of Programmable Logic Controller; speech chip is connected by digital circuit with the signal controlling port of Programmable Logic Controller; speaker is connected by analog circuit with speech chip; exterior display screen is connected by digital circuit with Programmable Logic Controller with external video signal; induction apparatus can be an infrared inductor; the ultrasonic sensing device; any in the microwave sensor; induction apparatus can be installed in the outside or inner of display screen; power supply is given induction apparatus respectively by lead; Programmable Logic Controller; speech chip and speaker power supply; induction apparatus is gathered human body eye signal and is passed to Programmable Logic Controller; the demonstration and the time switch of the instruction control exterior display screen that Programmable Logic Controller produces; and control speech chip; make speech chip produce voice signal and drive speaker; power supply is powered to induction apparatus; Programmable Logic Controller and speech chip; external video signal can be input in the Programmable Logic Controller and handle, and the signal of handling outputed in the exterior display screen shows.
Operation principle of the present utility model is: induction apparatus, and any by in infrared inductor, ultrasonic sensing device, the microwave sensor passes to Programmable Logic Controller with the distance signal of human body eye and induction apparatus;
Programmable Logic Controller is handled induction apparatus information, produces control signal, has visual prompts and time switch effect, be used for producing the screen information and cut off video signal, and the control speech chip is worked in good time;
Speech chip produces predetermined voice, by the speaker reminds people, keeps the distance of human body eye and induction apparatus;
Speaker, the voice messaging that speech chip is produced changes into sound.
The beneficial effects of the utility model are: simple in structure, be easy to realize that convenient and practical, by voice reminder and visual prompts dual mode, reminds people keeps the distance with display screen effectively, thus make people's health preserving good with the eye custom.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As depicted in figs. 1 and 2; a kind of distance control vision protector; comprise induction apparatus; Programmable Logic Controller; speech chip; speaker and power supply; Programmable Logic Controller comprises screen prompt system and time switch system; induction apparatus is connected by analog circuit with the signals collecting port of Programmable Logic Controller; speech chip is connected by digital circuit with the signal controlling port of Programmable Logic Controller; speaker is connected by analog circuit with speech chip; exterior display screen is connected by digital circuit with Programmable Logic Controller with external video signal; induction apparatus can be an infrared inductor; the ultrasonic sensing device; any in the microwave sensor; induction apparatus can be installed in the outside or inner of display screen; power supply is given induction apparatus respectively by lead; Programmable Logic Controller; speech chip and speaker power supply; external video signal can be input in the Programmable Logic Controller and handle, and the signal of handling outputed in the exterior display screen shows.
Work process of the present utility model is: according to above-mentioned steps device assembles is finished, the circuit connection finishes, and user can independently be provided with the setting value of induction apparatus distance measurement value, the timing time of intervalometer, the content of voice reminder and the content of screen prompting by Programmable Logic Controller before equipment used.When equipment is started working, suggestion with eye distance from greater than 50 centimetres (TV classes should greater than 150 centimetres) and as setting value, utilize the distance of induction apparatus sensing technology induction human body eye and display screen, receive the distance measurement value of induction apparatus by Programmable Logic Controller, and with setting value relatively, if the distance measurement value of induction apparatus is greater than setting value, then control signal turns back to induction apparatus, and equipment turns back to initial duty and continues the induction periodic duty; In case distance measurement value is less than setting value, Programmable Logic Controller just can be controlled speech chip and send voice reminder by speaker, the time switch of Programmable Logic Controller triggering simultaneously picks up counting, if get back in the range of set value at the distance measurement value of timing range interoceptor, then Programmable Logic Controller sends instruction to speech chip, stop voice reminder by the speech chip control loudspeaker, simultaneously equipment turns back to initial duty, and induction apparatus is responded to again and obtained distance measurement value; If the time of voice reminder has surpassed timing range, distance measurement value is still less than setting value, then Programmable Logic Controller can control display screen eject information, distance measurement value is obtained in the induction of induction apparatus continuation simultaneously, if this moment, distance measurement value was got back in the range of set value, then control signal turns back to induction apparatus, and equipment turns back to initial duty, closes display screen otherwise Programmable Logic Controller can send instruction; After display screen is closed automatically, must manually restart display screen, can rework; Programmable Logic Controller possesses timing function in addition, can come the demonstration time of control display screen by Programmable Logic Controller.
