Abstract
The utility model discloses a multi-angle eyesight protection device. The device comprises a microprocessor circuit. The microprocessor circuit is connected with a first 45 degree infrared distance measurement module, a second 90 degree infrared distance measurement module, a third 145 degree infrared distance measurement module, a memory cell, a voice horn, a liquid crystal module, a combination button, a reset switch, a power supply circuit and a relay control switch. A distance measurement angle adjusting scope of the first 45 degree infrared distance measurement module is 0-90 degree. A distance measurement angle of the second 90 degree infrared distance measurement module is 90 degree. The distance measurement angle adjusting scope of the third 145 degree infrared distance measurement module is 90-180 degree. The device adopts the infrared distance measurement modules to detect a plurality of different angles so that a problem that the single detection module can not fully cover all the scopes is effectively solved. Simultaneously, through using a distance and time mode to carry out combination control, problems that a distance is short and time is long when a teenager uses terminal display equipment are solved.
Description
Technical field
The utility model relates to a kind of vision protection device, particularly the infrared distance control device of a kind of multi-angle.
Background technology
Along with The development in society and economy, growth in the living standard, terminal screen (televisor, game machine and display) has been full of each corner in people's daily life.All kinds of screens convert power supply to light source, but direct projection stimulates eyes, shadow flicker sometimes, flickering, add the unreasonable setting of states such as tone, brightness, contrast, the randomness of angle changes, make image usually smudgy, very easily destroy normal visual balance.Although the simple myopia of teenager takes place, the mechanism of development is still indeterminate, generally sure be with closely, the time is long relevant with eye.
The utility model content
The utility model purpose: the purpose of this utility model is in order to solve deficiency of the prior art, and a kind of multi-angle vision protection device of the device of can cutting off the electricity supply automatically when using TV or display in non-correct or safe distance is provided.
Technical scheme: a kind of multi-angle vision protection device described in the utility model; comprise microcontroller circuit; described microcontroller circuit is connected with the one 45 degree infrared distance measurement module, the 2 90 degree infrared distance measurement module, the 3 145 degree infrared distance measurement module; storage unit; the voice loudspeaker, Liquid Crystal Module, combination button; reset switch, power circuit and relay control switch.
As preferably, described the one 45 degree infrared distance measurement module range finding angle of regulation range is 0～90 degree.
As preferably, described the 2 90 degree infrared distance measurement module range finding angle is 90 degree.
As preferably, described the 3 145 degree infrared distance measurement module range finding angle of regulation range is 90～180 degree.
As preferably, described power circuit is circumscribed with 220 volts of AC power.
As preferably, described relay control switch also is connected with terminal presentation facility.
As preferably, described the one 45 degree infrared distance measurement module, the 2 90 degree infrared distance measurement module and the 3 145 degree infrared distance measurement module range finding effective range are 80～350cm.
As preferably, described reset switch long by 3 seconds after, system recovers default setting automatically.
Beneficial effect: this device adopts the infrared distance measurement module that a plurality of different angles are detected, with the single detection module of effective solution scope is covered incomplete problem, by adopting distance and temporal mode to make up control, use terminal presentation facility apart from weak point, long problem of time with effective solution teenager simultaneously.
Description of drawings
Fig. 1 is internal circuit configuration block diagram of the present utility model.
Embodiment
A kind of multi-angle vision protection device as shown in Figure 1; comprise microcontroller circuit; microcontroller circuit is connected with the one 45 degree infrared distance measurement module; the 2 90 degree infrared distance measurement module; the 3 145 degree infrared distance measurement module; storage unit; the voice loudspeaker; Liquid Crystal Module; combination button, reset switch, power circuit and relay control switch; wherein the one 45 degree infrared distance measurement module range finding angle of regulation range is 0～90 degree; the 2 90 degree infrared distance measurement module range finding angle is 90 degree, and the 3 145 degree infrared distance measurement module range finding angle of regulation range is 90～180 degree, and power circuit is circumscribed with 220 volts of AC power; relay control switch also is connected with terminal presentation facility, the one 45 degree infrared distance measurement module; the 2 90 degree infrared distance measurement module and the 3 145 degree infrared distance measurement module range finding effective range are 80～350cm.
The utility model is formed multi-angle infrared human body induction range finding probe by three infrared distance measurement modules, detects the situation in the preset range, controls by distance and temporal mode respectively:
Distance mode: after the non-correct scope of apparatus settings, after human body enters default non-correct scope and keeps a period of time, system will send voice warning; After repeatedly alarming, if position of human body does not leave non-correct scope yet, microcontroller circuit cuts off the power supply of terminal presentation facility by relay; After human body left non-correct scope, microcontroller circuit was by the power supply of relay recovery terminal presentation facility.
Temporal mode: enter the effective monitoring scope of default infrared module detection when human body after, system will record the working time of display device automatically; After surpassing Preset Time working time, microcontroller circuit is by the power supply of relay cut-out terminal presentation facility, and after suspending a period of time (can set by combination button), microcontroller circuit is by the power supply of relay recovery terminal presentation facility.
This device adopts the infrared distance measurement module that a plurality of different angles are detected, with the single detection module of effective solution scope is covered incomplete problem, by adopting distance and temporal mode to make up control, use terminal presentation facility apart from weak point, long problem of time with effective solution teenager simultaneously.
