A plurality of buttons 216 on the television set 220, more than under be respectively reception room button, gate button, monitor button, television set button.The pattern of each indicator light 214 each corresponding button of indication.
Fig. 2 represents the circuit structure of an embodiment of television set double as call gate device of the present invention.Circuit structure of the present invention mainly comprises call gate circuit part 300 and TV set circuit part 400.
Call gate circuit part 300 has and is used for the pecker CNT1 that is connected with outdoor unit.Also have in addition and be used for the switching device shifter that television set/monitor switches, for example relay R Y1; Be used to switch the switching device shifter that is connected with reception room/gate, for example relay R Y2; Be used to switch the switching device shifter of phone/inside line, for example relay R Y3.
Relay R Y1 is according to control signal C 3Switch, when selecting the television set pattern, switch to vision signal and the sound signal that to supply with from TV set circuit part 400 and resupply the TV set circuit part; When selecting MONITOR MODE or big door model, switch to vision signal and the voice signal that to supply with from outdoor unit and supply with TV set circuit part 400.
Relay R Y2 is according to control signal C 4Switch, when selecting the reception room, switch to circuit L 2T is connected with audio-frequency transformer; When selecting the gate, switch to circuit L 1Audio line be connected with audio-frequency transformer T.
Relay R Y3 is according to control signal C 5Switch, when selecting telephony mode, switch to circuit L 3TEL is connected with telephone circuit; When the inside line pattern, switch to audio-frequency transformer T and be connected with telephone circuit TEL.
Telephone circuit TEL comprises figure disc part DL and electrophone RT.Loud speaker SP 1Be as sending the acoustical generator of ring tone, it be by with telephone line L 3The ring tone detector DET that connects 1The tone signal that takes place and by audio-frequency transformer T, utilize the voice signal of calling out reception room or gate to drive to send ring tone.
The alternating current of AC/DC converter CONV input 110V or 220V, output direct current 15V and B+ direct current.The power supply of direct current 15V is by switching device SC 1Excitation power supply as TV set circuit part 400 is supplied with TV set circuit part 400, in addition, and by switching device SC 2As the outer unit of the direct current 12V power supply supply chamber of outdoor unit.
Switching device SC 1According to control signal C 1, Switching power is supplied with; Switching device SC 2According to control signal C 2, after carrying out the AC/DC conversion, supply with direct current 15V.
Control circuit CTR is according to reception room button B 1, gate button B 2, monitor button B 3With television set button B 4Press action, drive the LED that is used to show this pattern 1～LED 4Show, and produce control signal C 1～C 5In addition, import the detector DET that is connected with the reception room circuit 2Detection signal after, generate and to be used for control relay RY 2, RY 3Control signal C 4, C 5Unaccounted symbol AMP is a sound signal amplifier.
TV set circuit part 400 comprises tuner 402, intermediate frequency transformer (IF) 404, video signal preprocessor 406, picture tube (CR T) 408, audio signal processor 410 and loud speaker 412 as the color TV machine circuit, tuner 402 is connected with antenna, by tuning this frequency of channel selection; Demodulation and detection go out intermediate frequency the frequency of this channel that intermediate frequency transformer 404 is selected from tuner 402, export high-frequency signal and sound signal respectively; Video signal preprocessor 406 receives and handles the vision signal of input; CRT408 is according to the output signal displayed image of above-mentioned video signal preprocessor 406; Audio signal processor 410 receives and handles the sound signal of input; Loud speaker 412 is according to the output signal output sound of above-mentioned audio signal processor 410.
The effect of the present invention of this formation is as follows.
Under the state of supplying with AC power commonly used, press television set button B 4When selecting the television set pattern, relay R Y 1Switch to the television set pattern, TV set circuit part 400 is just carried out television function.At this moment, switching device SC 1Connect, power supply is in the power connection state to TV set circuit 400 power supplies.Therefore, the user can TV reception by selecting desirable channel.
In the process of TV reception, when the visitor pressed call button 130 on the outdoor unit, the transmission of the audio line of call signal road L1 along the line by relay R Y2 and audio-frequency transformer T, was sent to loud speaker SP1 and sends ring tone.After the user hears ring tone, pick up electrophone RT and press gate button B 2The time, relay R Y1 just switches to MONITOR MODE, so, road L along the line 1Visitor's the picture intelligence of video line transmission by relay R Y1, on the picture tube 408 of television set, demonstrate image.Therefore, the user just can monitor the visitor, communicates with each other with the visitor.
Because when the user presses monitor button B 3The time, relay switches to MONITOR MODE at RY1, demonstrates outside situation on the picture tube 408 of television set, so, in indoor situation outside can monitor door.
When the user presses reception room button B 1The time, relay R Y2 just switches to the reception room pattern, circuit L 2By relay R Y 2And audio-frequency transformer T is connected with electrophone RT, therefore, can converse mutually with the reception room inside line, and the conversion by the reception room, can also converse with other families.
In addition, when being connected, by the ring tone detector DET of telephone wire with telephone wire 1After detecting ring tone, send control circuit CRT to, produce control signal C by control circuit CRT 5, make relay R Y 3Switch, thereby electrophone RT and telephone wire are connected.
As mentioned above, because structure of the present invention not only has the video doorphone function, and have the television set function concurrently, use so can be used as television set at ordinary times, when carrying out the call gate function, can be used as monitor uses, because a table apparatus has two kinds of functions, thus not only economy but also effective, when carrying out visual function of the present invention, owing to be to show, so can make the image that is monitored show more clearly with the resolution of television set.
