Description
[ technical field ]
The invention relates to the technical field of intelligent set top boxes, in particular to an anti-myopia early warning system of an intelligent set top box.
[ background art ]
Along with the development of the times, more and more electronic products are used in our lives, and the people do not depend on the use of the electronic products in life or work, so that the eyesight of the people is not slightly burdened. In family life, children often have the time of watching TV alone, but their self-eye protection consciousness has not been established yet completely, needs parents to supervise and remind them to keep a certain distance with the TV display screen, and at this time, parents can cause irreversible injury to children's eyes if not noticing. The set top box with the eye protection function can realize that when a person is too close to the display screen, an alarm is sent out in the form of pop-up frame display or prompt tone, so that the user is reminded to keep away from the display screen, and the purpose of eye protection is achieved.
[ summary of the invention ]
In order to overcome the problems in the prior art, the invention provides an intelligent set top box myopia prevention early warning system
The scheme for solving the technical problem is to provide an intelligent set top box myopia prevention early warning system which comprises a set top box main body, and an optical system, a pyroelectric infrared sensor, a signal filtering and amplifying circuit, a signal processing circuit and an alarm circuit which are arranged in the set top box main body;
the pyroelectric infrared sensor is positioned on the front side of the set top box main body, and a signal window is further arranged on the front side of the set top box main body; the pyroelectric infrared sensor penetrates through the signal window to detect a human body in front of the set top box main body in real time.
Preferably, the signal window is a fresnel lens; the Fresnel lens focuses infrared rays radiated by a human body onto the pyroelectric infrared sensor, and simultaneously generates alternately-changed infrared radiation high-sensitivity areas and blind areas so as to adapt to the characteristic that the pyroelectric detecting element requires continuously-changed signals.
Compared with the prior art, the intelligent set top box anti-myopia early warning system is a set top box with an eye protection function, and can achieve the purpose that when a person is too close to a display screen, an alarm is sent out in the form of pop-up frame display or prompt sound so as to remind the person to get away from the display screen, and the purpose of eye protection is achieved.
[ description of the drawings ]
Fig. 1 is a schematic diagram of a functional principle architecture of an intelligent set-top box myopia prevention early warning system of the invention.
[ detailed description of the invention ]
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1, an intelligent set-top box myopia prevention early warning system 1 of the present invention includes a set-top box main body, and an optical system, a pyroelectric infrared sensor, a signal filtering and amplifying circuit, a signal processing circuit and an alarm circuit which are arranged inside the set-top box main body;
the pyroelectric infrared sensor is positioned on the front side of the set top box main body, and a signal window is further arranged on the front side of the set top box main body; the pyroelectric infrared sensor penetrates through the signal window to detect a human body in front of the set top box main body in real time.
The set top box with the myopia prevention early warning system is realized based on the principle of pyroelectric effect. Pyroelectric sensor fixes at the inside front of STB, sees through the signal window, carries out real-time human body detection to STB the place ahead, in case someone and distance are too close, will pop out and play the frame and send out the police dispatch newspaper sound, reminds child and head of a family simultaneously.
The eye protection prompting function is realized based on the principle of pyroelectric effect. The myopia-preventing early warning system consists of mainly optical system, pyroelectric infrared sensor, signal filtering and amplifying circuit, signal processing circuit, warning circuit and other parts
Preferably, the signal window is a fresnel lens; the Fresnel lens focuses infrared rays radiated by a human body onto the pyroelectric infrared sensor, and simultaneously generates alternately-changed infrared radiation high-sensitivity areas and blind areas so as to adapt to the characteristic that the pyroelectric detecting element requires continuously-changed signals.
The pyroelectric infrared sensor adopted by the design core has the advantages of simple manufacture, lower cost, strong anti-interference capability, high sensitivity, safety and reliability.
Fresnel lens: infrared rays radiated by a human body can be focused on the pyroelectric infrared detection element, and simultaneously alternately-changed infrared radiation high-sensitivity areas and blind areas are generated so as to adapt to the characteristic that the pyroelectric detection element requires continuously-changed signals;
the pyroelectric infrared sensor is a core device in the design of an alarm, and can convert infrared signals of a human body into electric signals for a signal processing part to use;
the signal processing is mainly to amplify, filter, delay and compare the weak electric signals output by the sensor, and lays a foundation for realizing the alarm function.
Compared with the common set top box, the set top box is more targeted by the public, is more suitable for families with children, can help protect the eyesight of the children, solves the problems that parents want to give the children some time to watch television and cannot watch the children at all times, enhances the market competitiveness of the product, and is wide in user groups.
Compared with the prior art, the intelligent set top box myopia prevention early warning system 1 is a set top box with an eye protection function, and can achieve the purpose that when a person is too close to a display screen, an alarm is sent out in the form of pop-up frame display or prompt sound so as to remind the person to get away from the display screen, and the purpose of eye protection is achieved.
The above-described embodiments of the present invention do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
