Description
Technical field
The invention belongs to household appliance technical field, be mainly concerned with about TV and the two-way intelligent monitor system of outdoor doorbell.
Background technology
Along with improving constantly of living standard, each consumer wishes more that in modern family, household electrical appliances can really be realized the design of hommization, satisfy the demand of individual character.For example in China, all there is a TV in general family, except appreciating program, also I hope he can be brought into play more effect, serves family, and our this invention is exactly dexterously outdoor doorbell and television set to be combined, the realization image shows, and the two-way transmission of voice.
At present, the video doorbell system of market sale is generally 4 cun black and white or colorful visualization, and its picture is narrow, takies the interior space, and cost is higher.The present invention intends realizing the automatic switchover of television image and doorbell image.When television set normal play program, after the visitor pressed doorbell, television image converted visitor's image immediately automatically to, and TV is transformed into former tv programme picture automatically behind 15 paper money; When television set was in shutdown (standby) state, the someone pressed doorbell, and television set moment Auto Power On shows visitor's image, and television set is closed automatically after 15 seconds.At indoor hand held television set remote-controller, can realize to outdoor supervision, for strange visitor or be reluctant the people that receives can stop video picture, double-directional speech intercommunication, for the visitor who is ready to enter, can the remote control electric door lock etc. function, enjoy intelligent scientific and technological new life easily.This intelligent television monitoring system, innovation has solved the difficult problem of existing colorful visual doorbell video picture visual field weak effect.
Summary of the invention
The technical issues that need to address of the present invention, be that video doorbell at present sale still has the inconvenience part, not only picture is narrow, its special-purpose picture reproducer also will take the interior space, and cost height, in order to overcome these inconveniences, this patent provides a kind of technical scheme that doorbell and television set are combined, and realizes the two-way interaction transmission of pictures and sounds.Purpose of the present invention, be to take following technical scheme to realize, the two-way intelligent monitor system of a kind of TV-doorbell, mainly comprise doorbell control unit, television set unit and remote control unit, it is characterized in that, described doorbell control unit, it receives, amplifies transmission circuit by sound, image pickup, processing transmission circuit, light is augmented circuit and control signal circuit 4 parts formation automatically; Described television set unit, it is by sound reception, demodulation amplifying circuit, and sound is modulated, amplification emissioning circuit, the video image display circuit, control signal circuit 4 parts constitute; Described remote control unit, it by sound receive, the demodulation amplifying circuit, sound modulation, amplification, radiating circuit, control signal generation circuit 3 parts constitute.Described doorbell control unit adopts the YYH253GW module, receive, amplify transmission circuit by sound, sound is sent audio signal here by the miaow head on the doorbell, through amplifying, wired audio input end of transporting to television set, described image are the video images by the picked-up of the camera on doorbell visitor, after the internal element circuit is handled vision signal, output CVBS composite video signal, signal amplitude is 1Vp, the output of 75 Ω standards; The camera f-number is about 2.8,112 ° at visual angle (H), 82 ° (V).Described auto iris supplement system has an automatic light sensation device in the doorbell control unit; When light is dark, the light sensation device can be exported high level, driving lighting device brightens its light, after the visitor presses doorbell, illuminating lamp on the doorbell machine can change according to outdoor light intensity, automatically regulate light filling brightness, no matter wet weather or night, colorful visualization all can reach satisfied visual effect.Sound reception in the described television set unit, modulation, amplifying circuit, it is CIF16B that a demodulating unit master chip is arranged in this circuit, transports to the loudspeaker in the doorbell after the audio signal demodulation that the remote controller place is transmitted, the amplification.Described sound modulation, amplification, radiating circuit, master chip is CRT19T in this circuit, to the audio signal that the doorbell place is transmitted modulate, amplifying emission outputs to loudspeaker.
This system can be widely used in high-rise building, residential quarters, villa, hotel and other monitoring and management place.In the use, after television set was received this control signal, if television set is just when open state normal play program, after the visitor pressed doorbell, television image can convert visitor's image to immediately automatically, and TV is transformed into former tv programme picture automatically behind 15 paper money; If when television set was in shutdown (standby) state, the someone pressed doorbell, television set moment Auto Power On shows visitor's image, and television set is closed automatically after 15 seconds.When television set showed visitor's image, visitor's sound promptly was sent to television set, and the voice signal that the wireless-modulated transmitter unit in the television set is about to send here amplifies modulation, emission.Receiving element in the remote controller is promptly to audio signal demodulate reception, the amplification of television transmission like this.By the earphone socket on the remote controller, plug in the earphone and can receive visitor's sound, because the audio emission unit of the sound receiving element of remote controller and television set all is the duplex simultaneous two-way mode, get final product the receiving demodulation audio signal, can modulate audio signals again.Also have a miaow head in remote controller, owner can be by speaking facing to remote controller like this, and remote controller is about to voice signal modulation, emission.The audio signal demodulate reception that receiving element in the television set can emission comes is amplified, again with this audio signal wire transmission to outdoor doorbell, owner is in the indoor two-way interaction that just can realize voice with outdoor visitor like this.Beneficial effect of the present invention is that this system combines outdoor doorbell and television set, saves space and cost, realizes two-way intelligent distant control.
