Abstract
The utility model relates to the technical field of a distance control device, in particular to a distance control device for watching TV, which comprises a box and a power line. The front end of the box is provided with an infrared scanning and inducing panel, an infrared induction device which comprises a pulse trigger circuit, an infrared detection inductor, an amplifying circuit, a mode judgment and comparison circuit, a power control circuit and an AC/DC power circuit and which is connected with the power line is arranged in the box. When sensing people be close to the infrared scanning range preset at the front of a TV and stay over the preset time, the distance control device can automatically judge, cut off the power of the TV and supply power to the TV again in a preset time after people leave so as to control the distance of watching TV, protect eyes of children and youths and help children and youths form good habit of watching TV.
Description
Technical field:
The utility model relates to the distance control device technical field, refers in particular to a kind of television set and views and admires distance control device.
Background technology:
As everyone knows; if viewing and admiring the distance of TV controls badly; infringement is very big to the ray that television set sends to eyes; very easily harm one's eyes; cause eyesight to descend; especially the health of youngsters and children also is in growth and development stage; it is perfect that the physical function of each side and organizing is not also grown; if at this time make eyes be in abnormal state; be easy to make eye fatigue excessive, bring out glaucoma; myopia; TV eyes such as astigmatism, this just modern society to get bathomorphic people more and more; and one of more and more littler reason of age of onset, therefore effectively our eyes of protection and the control distance relation of viewing and admiring TV is close.Existing TV is to set the unused time, and reminds people is taken a good rest, but uncontrollable to viewing distance, and youngsters and children is not had actual vigilant effect yet.
The utility model content:
The purpose of this utility model is exactly that the television set that provides a kind of children's of protecting young people eyes at the deficiency of prior art existence, reminds youngsters and children control to view and admire the TV distance is viewed and admired distance control device, forms the custom of correctly viewing and admiring TV to help youngsters and children.
To achieve these goals, the technical solution adopted in the utility model is: it comprises box body, power line, is provided with the noctovisor scan induction panel at the front end of box body, is provided with the infrared induction device that is connected with power line in the box body.
Described infrared induction device comprises pulsed triggering circuit, ultrared sensing inductor, amplifying circuit, pattern judgement comparison circuit, power control circuit and AC/DC power circuit, ultrared sensing inductor, amplifying circuit, pattern judge that comparison circuit is connected in order successively with power control circuit, and the output of AC/DC power circuit and pulsed triggering circuit is connected with the input of ultrared sensing inductor respectively.
The utility model beneficial effect is: the utility model is provided with the noctovisor scan induction panel at the front end of box body, be provided with the infrared induction device that is connected with power line in the box body, described infrared induction device comprises pulsed triggering circuit, the ultrared sensing inductor, amplifying circuit, pattern is judged comparison circuit, power control circuit and AC/DC power circuit, the ultrared sensing inductor, amplifying circuit, pattern judges that comparison circuit is connected in order successively with power control circuit, and the output of AC/DC power circuit and pulsed triggering circuit is connected with the input of ultrared sensing inductor respectively; In sensing the close television set front preset noctovisor scan scope of human body, stop when surpassing Preset Time; can judge the cut-out TV set power automatically; human body leaves after by preestablishing the supply of time recovery TV set power, view and admire television set distance, the children's eyes of protecting young people to reach control, help youngsters and children to form the purpose of correctly viewing and admiring television habits.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the frame principle figure of the utility model infrared induction device.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see shown in the accompanying drawing 1,2, a kind of television set is viewed and admired distance control device, it comprises box body 1, power line 2, the outside of box body 1 is provided with socket, socket is connected with the attaching plug of television set, also be provided with switch on the box body 1, be used to control the break-make of the utility model power supply, power line 2 is to be connected with the power supply of outside, for each circuit provides power supply, be provided with noctovisor scan induction panel 3 at the front end of box body 1, be provided with the infrared induction device 4 that is connected with power line 2 in the box body 1; Described infrared induction device 4 comprises pulsed triggering circuit 41, ultrared sensing inductor 42, amplifying circuit 43, pattern judgement comparison circuit 44, power control circuit 45 and AC/DC power circuit 46, ultrared sensing inductor 42, amplifying circuit 43, pattern judge that comparison circuit 44 is connected in order successively with power control circuit 45, and the output of AC/DC power circuit 46 and pulsed triggering circuit 41 is connected with the input of ultrared sensing inductor 42 respectively.
The function of foregoing circuit and components and parts is: pulsed triggering circuit 41 is as the power end that triggers infrared transmitter; Ultrared sensing inductor 42 is sweep limitss 5 that initiatively emission and detecting are set, and scatters infrared ray by noctovisor scan induction panel 3, and when detecting human body when entering sweep limits 5, output signal is to amplifying circuit 43; The function of amplifying circuit 43 is that the signal of ultrared sensing inductor 42 outputs is carried out processing and amplifying; Pattern judges comparison circuit 44 is to judge whether the signal that receives will cut off the power supply of television set, and the function of power control circuit 45 is to trigger the power supply that control switch switches on or off television set; The function of AC/DC power circuit 46 is that interchange 110V or 220V power source conversion are become Dc low voltage power supply, for inner each circuit provides power supply.
The utility model can be connected with television set easily, at first the attaching plug of television set is plugged in the socket of box body 1, and power line 2 is connected with indoor power supply, and the utility model is placed TV the place ahead; Connect the power supply of television set during beginning; 42 pairs of predefined sweep limitss 5 of ultrared sensing inductor scan; when detecting human body in sweep limits 5 and rest in the sweep limits 5 and to surpass original setting-up time; cut off the power supply of television set immediately; in human body leaves sweep limits 5 and through behind the Preset Time; automatically connect the power supply of television set, to reach the purpose that the control TV is viewed and admired distance, the children ' s vision of protecting young people.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and are included in the utility model claim.
