Abstract
The invention is an eyes protecting system of TV set, composed of voice prompting circuit and control output circuit, its character: a signal detecting circuit is set outside the voice prompting circuit and linked with an anti-interference processing circuit, and a signal processing circuit is set between the anti-interference processing circuit and voice prompting circuit to provide signal for the voice prompting circuit. When human body approaches to TV set, it makes a voice prompt and cuts off TV signal and when human body leaves TV set, it automatically resumes TV signal.
Description
Technical field:
The present invention relates to TV set device, particularly a kind of televisor eyeshield system.
Background technology:
Children see that the TV hypotelorism is to cause the children ' s vision main reasons for decrease.This is because television picture tube is a kind of cathode-ray tube (CRT), and the electron gun ejected electron is quickened through anode high voltage through after focusing on again, and the energy impact fluorescence screen with very big makes fluorescent powder send bright spot, also can go out harmful X ray to its ambient radiation simultaneously.Though the televisor of Sheng Chaning has generally all increased X-ray-preventing leakage circuit in recent years, in normal horizon range, can not cause injury to human body, eyesight, but for the preschool child, because ability of self control is poor, when appreciating interesting TV programme, tend to can't help near televisor.Children are in growth course, and the adjusting power of eyeball and eye muscle is poor, cross when near apart from televisor, and very strong screen exit rays has very big spread effect to eyes; Children are the most responsive to X ray in addition, therefore are subjected to the injury maximum of X ray, so see closely that for a long time TV will cause visual deterioration, cause that sometimes dizziness, vomiting, the busy power of note descend.
Summary of the invention:
Technical matters to be solved by this invention is: children see that the TV hypotelorism is to cause the children ' s vision main reasons for decrease.This is because television picture tube is a kind of cathode-ray tube (CRT), and the electron gun ejected electron is quickened through anode high voltage through after focusing on again, and the energy impact fluorescence screen with very big makes fluorescent powder send bright spot, also can go out harmful X ray to its ambient radiation simultaneously.Though the televisor of Sheng Chaning has generally all increased X-ray-preventing leakage circuit in recent years, in normal horizon range, can not cause injury to human body, eyesight, but for the preschool child, because ability of self control is poor, when appreciating interesting TV programme, tend to can't help near televisor.Children are in growth course, and the adjusting power of eyeball and eye muscle is poor, cross when near apart from televisor, and very strong screen exit rays has very big spread effect to eyes; Children are the most responsive to X ray in addition, therefore are subjected to the injury maximum of X ray, so see closely that for a long time TV will cause visual deterioration, cause that sometimes dizziness, vomiting, the busy power of note descend.The present invention provides televisor eyeshield system for the technical scheme that above-mentioned technical matters adopted that solves in the prior art, described this televisor eyeshield system is made of voice warning circuit and controlling output circuit, it is characterized in that described voice warning circuit outer setting has signal deteching circuit, described signal deteching circuit is connected with the anti-interference process circuit, be provided with signal processing circuit between described anti-interference process circuit and the described voice warning circuit, described signal processing circuit provides signal for described voice warning circuit, described signal processing circuit is connected with a counter, described signal processing circuit provides control signal to counter, the signal of described counter passes to described controlling output circuit, described controlling output circuit outputs control signals to the television signal circuit, concrete, described controlling output circuit outer setting has delay circuit, described signal deteching circuit detects distance by infrared sensor, and described anti-interference process circuit is provided with anti-shake function.
The present invention and prior art contrast, and effect is positive and tangible.Televisor eyeshield of the present invention system can realize as human body near the time TV function send voice suggestion, cut off TV signal; When human body leaves sensing range, recover TV signal automatically, thereby protected people's eyesight well.
Description of drawings:
Fig. 1 is the structural representation of a preferred embodiment of televisor eyeshield of the present invention system.
As shown in Figure 1, televisor eyeshield system voice cue circuit 1 of the present invention and controlling output circuit 2 constitute, it is characterized in that described voice warning circuit 1 outer setting has signal deteching circuit 3, described signal deteching circuit 3 is connected with anti-interference process circuit 8, be provided with signal processing circuit 7 between described anti-interference process circuit 8 and the described voice warning circuit 1, described signal processing circuit 7 provides signal for described voice warning circuit 1, described signal processing circuit 7 is connected with a counter 4, described signal processing circuit 7 provides control signal for counter 4, the signal of described counter 4 passes to described controlling output circuit 2, and described controlling output circuit 2 outputs control signals to television signal circuit 5.Described controlling output circuit 2 outer setting have delay circuit 6, and described signal deteching circuit 3 detects distance by infrared sensor, and described anti-interference process circuit 8 is provided with anti-shake function.
