VH SW4-6 FM SW1-3
VL SW1-3 SW4-6 FM
If shortwave is designed to a wave band, the triode V17 in the wireless channel wave band transducer, and relay J 2, two wave band AM of control broadcast receiver, SW, broadcast receiver are FM, AM, SW triband.
VL, VH, three frequency ranges of U obtain identical broadcast receiver frequency band and arrange, and are convenient to memory as FM, AM, SW, and are easy to use, and concrete analyzing examples is as follows: be about to SW1-3 and be arranged to SW, obtain as following table and SW4-6 is arranged to AM.
Channel standard 234
U FM SW AM
VH AM FM SW
VL SW AM FM
If being connected with the triode of logic gates input, intercourses the socket of remote control panel (P11-14,15) signal end.Promptly control standard 2,4 input codes are replaced mutually with BL voltage, VL channel broadcast receiver frequency permutation is FM AM SW, in like manner control standard 2,3 input codes are replaced mutually with BH voltage, in like manner control standard 3,4 input codes are changed mutually with BU voltage, VL like this, VH, the U channel obtains the aligned identical of broadcast receiver frequency band.If with in like manner, VL channel broadcast receiver frequency permutation is FM AM SW, replaces mutually from BH, the BL voltage of remote control panel, and BU, BL voltage are replaced mutually, obtain the aligned identical of broadcast receiver frequency band.
The gate that the foregoing description provides is with the embodiment of triode input.But the input that constitutes gate with MOS circuit, TTL logical circuit or other gate circuit does not exceed scope of the present utility model.
Standard 2,3,4 yards can be used this switch to search for, store automatically three kinds of different triband radio programs of arranging automatically respectively, at VL, VH, the arbitrary channel of U in same channel, utilizes standard 2,3, can search for for 4 yards, storage triband broadcast receiver, this also is the practical part of unit switch change-over circuit design.Sound is difunctional in the picture, see TV on one side, listen to the radio on one side, at first with television high frequency head V7S-72H7 tuning voltage VT end capacitor C 104,0.1UF and meet capacitor C 0.33UF/50V, when tv state is transformed into broadcast receiver, increase television set tuning voltage VT terminal voltage storage capacity, television set automatic gain control AGC voltage (R220) will be adjusted simultaneously.Concrete operations are given an example, the program number zoning, and TV is stored in 0-59, the VL channel TV program storage of seeing is at 60 program numbers, and 61-69 stores the standard 2,3 of VL channel, 4 yards is the radio programs of triband, the VH channel TV program storage of seeing is at 70 program numbers, and 71-99 stores the standard 2,3 of VH channel, 4 yards radio programs, the U channel TV program storage of seeing is at 80 program numbers, and 81-89 stores the standard 2,3 of U channel, 4 yards radio programs, as program number 60, at this moment the screen display standard 1, and relay J 1 is a tv state, press the remote controller standard, at this moment standard 2 shows, relay J 1 is radio reception state, standard 2,3,4 yards are the radio reception state, the red standard 2 of screen display, and (it is not too long to notice that standard 1 forwards time of standard 2 to, otherwise red standard 2 becomes green, when returning 60 program numbers, standard 2 be become standard 1, TV programme just can occur.) order channel selection program number is increased to 61-69, kept television image, and broadcast receiver sound is arranged again, program number returns 60, is again former TV programme and sound accompaniment.Directly program number selects the triband radio programs of VL channel, returns former TV programme then, and is easy and simple to handle, need not to regulate.The operating process of VH, U channel is with the VL channel.
Utilize TV x-ray protection function, the television set that breaks is capable, frame part, and Full remote controlled television field frame and radio programs.The TV programme that certain time period need not see, the television set that breaks is capable, the frame part.Disconnect former television set integrated circuit (IC) 801-30 and R644 wiring.During television operations, by Z3 (6,7), K1 connects television set IC801-30 and R644 wiring; During radio reception, television set integrated circuit (IC) 801-30 receives diode D1,2, and promptly on the 1.2V, the television set that breaks is capable, the frame part.1.2V take out from the 3V source of stable pressure, play protective effect, triode V21,22,23 form the 3V stabilized voltage power supply.The television set that breaks is capable, and after the frame part, when accepting television field frame, K switch 1 needs connection+5V to remote control panel IC1-34, otherwise does not have television field frame.Select the program number video screen bright line to occur, K switch 1 disconnects the input of remote control panel P8-20 identification signal, and resistance R 201 disconnects with IC1-34.Television set is capable, when frame is partly worked, connects integrated IC801-30 of television set and R644 wiring again by socket Z3 (6,7) K switch 1, and receiving TV has blue background.Change-over circuit K1 is capable for disconnected television set among the figure, frame state.The control of broadcast receiver volume with a 3V voltage-stabiliser tube D6 protection, changes triode V24 base stage and collector voltage from remote control panel socket P2-6 output, changes Sony IC CXA1019M-4 direct voltage, the control volume.
The television set that breaks is capable, frame part, and Full remote controlled television field frame and radio programs.The TV programme that certain time period need not see, the television set that breaks is capable, the frame part, power saving, large screen television is all the more so.The prevention TV syndrome.Adopt the triband broadcast receiver of Sony IC CXA1019M functional, working stability.Not with digital Sony IC CXA1019M broadcast receiver and the radio channels unit switch transducer that shows of frequency, about 50 yuan of cost price.Broadcast receiver has used band switch, duplex, and volume potentiometer, complex structure, and also the life-span is also limited.Now adopt electric tuning.Electric tuning needs the above direct voltage of 12V, and stable 30V voltage is arranged in the television set, and broadcast receiver has used television set tuning voltage VT, and is both stable, remote-controlled again.Had the desirable audio frequency power amplifier system of television set, both saved money, effect is good again.And in television set when work, because broadcast receiver does not need work, disconnect standard 2,3,4 decoding circuits, and broadcast receiver frequency band transducer does not need work basically.
