Description
Technical field
This utility model belongs to technical field of electronic equipment, is specifically related to a kind of prevent and treat the device that television set affects one's power of vision.
Background technology
Along with the raising of quality of life, it is more and more longer for object time that people watch TV Festival.It may be said that our life be unable to do without TV, and this needs to spend the plenty of time to be sitting on chair and just can complete, and research finds, human body is under normal circumstances, when the gradient of spinal column deviates normal physiological bending more than 15 degree, the time reaches 40 ~ 50 seconds, it is possible to form faulty posture custom.The long-term people before television set of great majority, can feel that eye is done astringent, have burning sensation or foreign body sensation；Somebody's vision instability or temporarily blurred vision；More having people's eyelid heavy, eyeball distending pain is even had a headache ... through ophthalmologic examination, and conjunctival congestion, visual deterioration occur in the eyes of such syndrome, and adjustment power goes down, and lacrimal secretion reduces, the symptom such as intraocular pressure rising time serious, is asthenopia syndrome by ophthalmologist's diagnosis.
To this, the design provides and a kind of prevents and treats the device that television set affects one's power of vision, can effectively solution the problems referred to above, the design can periodically monitor the sitting posture of people's distance with device and people, when distance is too near or sitting posture not to time, the prompting user that can give a warning does main modulation, it is possible to well prevent the myopia problem because sitting posture, distance etc. cause.The core devices being applied in design is infrared module, and infrared module is that the infrared ray by detection human-body emitting is operated.Detector is collected extraneous infra-red radiation and then gathers on infrared sensor, once invasion people enters in search coverage, human infrared radiation is focused on by part mirror, thus being received by pyroelectricity unit.Wherein, infrared scanner is the infra-red radiation according to tested atural object self, and the optical-mechanical by instrument itself scans and remote sensing platform moves the remote sensing instrument forming image along heading；And infrared range-measurement system is to utilize infrared ray to send from diastimeter to encounter after reverberation is reflected back and received by diastimeter, according to infrared ray from being issued to the time being accepted to and ultrared spread speed calculates distance.
Utility model content
The purpose of this utility model is that design a kind of prevents and treats the device that television set affects one's power of vision, it is possible to effectively prevent because when seeing TV, sitting posture not on or distance is too near and people's vision produces impact.
For this, this utility model provides a kind of prevents and treats the device that television set affects one's power of vision, including device body, switch, battery, display, keyboard, processor, buzzer, infrared module, wherein, device body is cuboid, display, keyboard are positioned at device body surface, battery, processor are positioned at inside device body, switch, buzzer, infrared module are respectively positioned on the positive side of device body, and switch, battery, display, keyboard, buzzer, infrared module all electrically connect with processor.
Above-mentioned a kind of device that television set affects one's power of vision of preventing and treating, described keyboard only adds, a key that subtracts two.
Above-mentioned a kind of device that television set affects one's power of vision of preventing and treating, described infrared module includes infrared scanner and infrared range-measurement system.
Above-mentioned a kind of device that television set affects one's power of vision of preventing and treating, described processor adopts STC15F2K32S2 single-chip microcomputer, and inside has 2KRAM, 32KFlash and 29KEEPROM, it is not necessary to outer extension memory again, stores the various parameter values that standard sitting posture is corresponding in memorizer.
Above-mentioned a kind of device that television set affects one's power of vision of preventing and treating, described device body volume is little, and it is convenient to place, and battery is rechargeable battery, and there is charging inlet device body rear surface.
The beneficial effects of the utility model: a kind of of this utility model offer prevents and treats the device that television set affects one's power of vision, when infrared module detect people from television equipment distance too close to or the sitting posture of people not in time, buzzer can remind user to adjust sitting posture and the distance with television set, has sitting correction set and the function of preventing and treating myopia.
Below with reference to accompanying drawing, this utility model is described in further details.
Accompanying drawing explanation
Fig. 1 a kind of prevents and treats the device schematic diagram that television set affects one's power of vision.
Description of reference numerals: 1, device body；2, switch；3, battery；4, display；5, keyboard；6, processor；7, buzzer；8, infrared module.
Detailed description of the invention
A kind of as shown in Figure 1 prevent and treat the device that television set affects one's power of vision, including device body 1, switch 2, battery 3, display 4, keyboard 5, processor 6, buzzer 7, infrared module 8, it is characterized in that: device body 1 is in cuboid, display 4, keyboard 5 are positioned at device body 1 surface, it is internal that battery 3, processor 6 are positioned at device body 1, switch 2, buzzer 7, infrared module 8 are respectively positioned on the positive side of device body 1, and switch 2, battery 3, display 4, keyboard 5, buzzer 7, infrared module 8 all electrically connect with processor 6.
The each side such as integrated cost, performance considers, what processor 6 was selected is that SOP28 encapsulates single-chip microcomputer STC15F2K32S2, it is the single-chip microcomputer of single machine cycle (1T), has at a high speed, highly reliable, super low-power consumption, the super advantage such as anti-interference, instruction code completely compatible traditional 8051.It is internally integrated highly reliable reset circuit, can be used on the occasions such as high-speed communication, Based Intelligent Control, strong jamming.There is inside it 2KRAM, 32KFlash and 29KEEPROM, utilize the EEPROM within this single-chip microcomputer can store standard sitting posture relevant parameter, it is not necessary to outer extension memory again.
Device is placed in television set side, it is sufficiently large that infrared module 8 measures scope, it is made without angle adjustment, after opening switch 2, by regulating adding above keyboard 5, subtract button and people's distance limit from device can be set, this fixed value shows that (such as books are at 33cm over the display, computer is more than 50cm, television set is that 2m is with first-class), the standard value set up is transferred directly in processor 6, infrared distance measurement instrument detection user from device distance and transfers data to processor 6, when this value is less than standard value time, processor 6 can send command signal, set out buzzer 7, give a warning, user is reminded to adjust distance；Infrared scanner is primarily used to correct faulty sitting posture, scanner gathers the related data (mainly the deviation etc. of the gradient of spinal column, sight line) of human body sitting posture and passes to processor 6, the relevant parameter of the standard sitting posture that processor 6 comparison data value has stored with realization, when measured data values finds given scope time, buzzer 7 also can give a warning.
It should be noted that infrared module 8 periodically (the detection cycle can adjust according to people's myopic degree, sitting posture custom etc.) detects, within such as 10 minutes, check once, so can save an energy.
Exemplified as above is only to illustration of the present utility model, is not intended that the restriction to protection domain of the present utility model, every belongs within protection domain of the present utility model with the same or analogous design of this utility model.
