Description
Technical field
The utility model is related to the TVs that a kind of TV more particularly to a kind of infrared induction control.
Background technology
In daily life, unclear to the safe distance of TV when child usually sees TV, like close to TV low coverage
From viewing, the phenomenon that be easy to causeing visual impairment with eye overlong time, occurs, and is unfavorable for the visual acuity of child, needs a kind of energy
Enough so that the equipment that child forms the custom of safe distance viewing TV programme.
Utility model content
The purpose of this utility model is that solve the above-mentioned problems and provides a kind of TV of infrared induction control.
The utility model is achieved through the following technical solutions above-mentioned purpose：
The utility model includes set-top box ontology, infrared induction switch, IC controllers, distance parameter memory, time electricity
Road and TV power supply control circuit are provided with the infrared induction switch on the TV ontology, the infrared induction switch
Output end is connect with the input terminal of the IC controllers, the input terminal of the output end of the IC controllers and the set-top box ontology
Connection, the data port of the IC controllers is connect with the data port of the distance parameter memory, on the IC controllers
It is provided with the time circuit, the triggering input terminal of the time circuit is connect with the triggering input terminal of the IC controllers.
Specifically, the infrared induction switch includes infrared inductor, difference amplifier and window comparator, it is described infrared
The output end of inductor is connect with the input terminal of the difference amplifier, the output end of the difference amplifier and the window ratio
Input terminal compared with device connects, and the output end of the window comparator is connect with the input terminal of the IC controllers.
Specifically, it is provided with keyboard input port on the IC controllers.
The beneficial effects of the utility model are：
The utility model can be by adjusting the operating distance of infrared induction switch on TV, when child enters infrared induction
After range, the display screen and picture of TV carry out control pausing operation by IC controllers to set-top box so that child forms peace
Full distance watches the custom of TV programme.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1, the utility model includes set-top box ontology, infrared induction switch, IC controllers, distance parameter storage
Device, time circuit and TV power supply control circuit are provided with the infrared induction switch, the infrared sense on the TV ontology
The output end of inductive switch is connect with the input terminal of the IC controllers, the output end of the IC controllers and the set-top box ontology
Input terminal connection, the data port of the IC controllers connect with the data port of the distance parameter memory, the IC
The time circuit, the triggering input terminal of the triggering input terminal and the IC controllers of the time circuit are provided on controller
Connection.
The infrared induction switch includes infrared inductor, difference amplifier and window comparator, the infrared inductor
Output end connect with the input terminal of the difference amplifier, the output end of the difference amplifier and the window comparator
Input terminal connects, and the output end of the window comparator is connect with the input terminal of the IC controllers.
The power module of its feeder ear of infrared inductor and set-top box connects, for incuding extraneous infrared signal, and will
Infrared signal is converted into electric signal, and is exported according to the variation of infrared signal for characterizing the changed electricity of extraneous infrared signal
Signal, window comparator is by the threshold value comparison of the voltage value of amplified electric signal and preset window.
Be provided with keyboard input port on the IC controllers, can by keyboard input infrared induction switch effect away from
From.
The reflection signal of infrared inductor reception staff, both signals can detect phase after difference amplifier amplifies
Difference variation, and through next stage by voltage comparator and setting threshold value comparison after, generate a switching drive signal, transmission
Start TV power supply control circuit to IC controllers and pause control is realized to set-top box.
Infrared induction signal while input difference amplifier, output end can obtain an output valve, when phase difference is one
When stationary value, output valve is also stable, it is only necessary to be continued cycling through.When phase difference is not a stationary value, output valve
It can fluctuate, fluctuation signal and a fixed voltage（Threshold value）Compare, when fluctuating range is more than threshold value, infrared induction module
It is output to IC controllers startup set-top box and carries out pause action.
We can open eyeshield pattern when child will see TV in the switch of the television remote control device function, away from
It is pre-set with a distance from infrared induction from parameter storage, once child close to TV touches screen or apart from screen mistake
Closely, after child enters infrared induction range, the display screen and picture of TV control TV power supply by IC controllers
It closes, when child leaves, time circuit triggering starts IC controllers and TV power supply control circuit opens TV
Action, by adjusting the operating distance of infrared induction switch so that child forms the custom of safe distance viewing TV programme.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all in this practicality
All any modification, equivalent and improvement etc., should be included in the guarantor of the utility model made by within novel spirit and principle
It protects in range.
