The circuit working principle of the utility model embodiment is as follows: (referring to Fig. 2)

After the power turn-on K switch 1, AC220V after diode D21-D24 rectification, provides stable voltage by three-terminal voltage-stabilizing IC circuit 15 to circuit through the transformer step-down.D20 this moment (LED) is luminous to do power supply indication, circuit get electric after, IC1, IC8, IC9, IC14 are all in addition clear automatically, enter to wait for and wait duty.

L1, L2 on the called logical back of telephone line and the line of answering can receive the ringing voltage of sending here on the switch, after the normally closed

interlock

2,3 of J1 is attached to capacitor C 12 and presses every landing vertically by the D10 amplitude limit, after the D11 rectification C10 filtering, send into the high level pulse signal to 14 pin (CP end) of IC8 through R2.IC8 counts displacement under the effect of pulse, behind the high level pulse that 4 rings of counting form, the 10th pin output high level of IC8 triggers 1/2IC9 the 11st pin, and 12 pin of monostable circuit upset IC9 are that high level makes the G13 saturation conduction through R5, relay J 1 adhesive.The high level of 12 pin of IC9 makes IC8 in addition clear through 15 pin that D12 is returned to IC8 simultaneously.Wait down task.Because of relay J 1 adhesive working contact switches, cut off sending into of ringing voltage, and connected resistance R 40 (R40 is the impedance of phone off-hook) simultaneously, words line automatic off-hook is finished.The 12 pin high level of IC9 are connected to its 3rd pin in addition, the monostable circuit upset that makes its second half IC9 form, and the 2nd pin output high level makes the G14 saturation conduction behind R7.The 7 pin ground connection of IC10, the audio oscillation starting of oscillation.The audio prompt signal, is recycled on the telephone line through capacitor C 4 after G15 amplifies by 4 pin, the prompting side of dialling the number, and speech channel is connected automatically.In relay J 1 adhesive, resistance R 58 is connected with power supply VC through the

contact

4,5 of J1, and control circuit gets clear automatically its 3 pin in addition of electric IC1 and enters the working signal receive status for the high level circuit.Can press the coding number this moment and carry out electrical equipment control.After telephone line was connected automatically, the audio frequency units encoded signals of encrypting usefulness every directly, was amplified after C14 is sent to 1 pin of electronic switch IC2 through triode G3 through C13 by circuit L1 again.Because of clear back 3 pin (YO) in addition of IC1 start are high level, K6 conducting when 6 pin of IC2 have high level.3 pin that signal passes to IC3, the IC4 sign indicating number that is situated between.When the frequency of the 5th, 6 pin of double-audio signal and IC3, the IC4 of input and the voltage controlled oscillator be made up of the resistance among capacitor C 40, C45, RK4, the RK5 was identical, the frequency phase lock ring lock of IC3, IC4 calmly.The 8th pin output low level of IC3, IC4.This low level pulse makes G4 end after D4, D5 and door are handled, and makes G5, G6 conducting, and G6 collector output high level pulse is to 11 pin that account for IC11, makes its bistable circuit the 13rd pin output stable state high level that overturns.High level on the G6 collector makes the G2 conducting through D2, R45 simultaneously, G1 transfers to and ending, 14 pin (CP) that collector output high level pulse triggers IC1 make IC1 carry out level shift, 3 pin of IC1 are that low level electronic switch K6 dead electricity is turn-offed, Jie's decoding circuit of first group is no longer worked, and this moment, 2 pin of IC1 were high level.Because of 2 pin of IC1 link to each other with 5 pin of IC2, electronic switch K7 lead angle makes second group of Jie's coded signal passage open-minded.The audio frequency of encrypting usefulness picks up the signal of digit code, by circuit L1, every logical, after triode G3 amplifies, is sent to 1 pin of electronic switch IC2 through C15 through C13, is resent to the 3rd pin of IC5, IC6, and sign indicating number is situated between.The 5th, 6 pin of double-audio signal and IC5, the IC6 of input and by capacitor C 17, C22, the resistance among resistance R K2, the RK3, when the frequency of the voltage controlled oscillator of composition was identical, the frequency phase lock ring lock of IC5, IC6 was calmly.The 8th pin output low level of IC5, IC6.This low level pulse ends triode G10 after D16, C17 and door processing, makes G11, G12 conducting.The collector output high level pulse of G12 makes its bistable circuit upset to 3 pin of 1/2IC11, the high level of the 1st pin output stable state.

Simultaneously, the high level pulse of triode G12 collector makes triode G2 conducting through D3, R45, and triode G1 ends, and 14 pin of collector output high level pulse triggering IC1 make level shift the 2nd pin output low level of IC1.Make electronic switch IC25 pin dead electricity K7 turn-off; Jie's sign indicating number phone of second group is no longer worked.This moment, encryption Jie sign indicating number work of 2 figure places was finished.Sign indicating number is finished because correct encrypted work is situated between.1 pin of integrated circuit (IC) 11: 13 pin are high level, after diode D6, D7 and door processing, triode G7 makes G8 enter stable saturation conduction state by by transferring conducting to, its current collection is high level very, and links to each other with 13 pin of IC2 and to make electronic switch K8 conducting.The passage of single channel control signal is open-minded.Because of the current collection of G8 very high level G9 enter saturation conduction, make electronic switch 6 pin dead electricity K6 enter the disconnected state of stable lock.(because of IC1 makes its displacement back, the 4th pin at second group of Jie's coded signal is that high level reaches 15 pin through diode D1, makes it in addition clear, and the 3rd pin (YO) is again a high level).Because electronic switch K6, K7 are all turn-offed reliably, any double-audio signal that transmits on the circuit all can not make Jie's decoding circuit work by IC3, IC4, IC5, IC6.So the duty of triode C8 can not change.Electronic switch K8 is also just stably open-minded.This moment 7 groups of single channel electrical equipment control sound signal (number of the 0-9 on sender side's telephone set).Amplify through C16, K8 through C12, G3, reach 3 pin of IC12, IC13, behind the sign indicating number that is situated between, the 8th pin output low level pulse, signal reach triode G17 and make it end, triode G18, G19 conducting after D18, D19 and door processing.The collector high level pulse of G19 to 1/2IC1411 pin monostable circuit overturns, 12 pin high level reach 3 pin of 1/2IC, make bistable circuit overturn the 1st pin be high level through R19, G20 saturation conduction, relay J 2 adhesives are connected load circuit and are finished the open-minded of single channel electrical equipment.In like manner to turn-off former this road electrical equipment of having opened,, just can turn-off as long as press former identical number.D25LED does luminous indication when circuit debugging.K9 is a toggle switch.Doing the conversion of the actuating of relay and small electrical magnet button actions uses.

Be converted to the monostable circuit end, triode G20 drives small electrical magnet button DZ (for infrared ray control household electrical appliances) and makes action button usefulness.In the monostable circuit upset of IC14.The high level of the 12nd pin reaches G14 through D14, makes the 7 pin ground connection of G14 saturation conduction IC10, the audio oscillation starting of oscillation, and 13 pin of IC14 transfer low level to, and G16 is transferred to by conducting and ending.The 4th pin of IC10, two groups of composite signals of 11 pin output, by on the capacitor C 4 foldbacks reply line, cue transmitting terminal, load circuit are opened or are turn-offed after G15 amplifies.This moment, remote-controlled operation work was finished.The circuit working of 7 groups of single channel controls is same as described above.After time-delay in 2 minutes, the monostable circuit of being made up of the 8th, 9,10,11,12 pin of IC9 restores, and the 12nd pin transfers low level G13 to and ends, relay J 1 dead electricity, each contact homing.The telephone line automatic hand-up, circuit is replied former state, and the control signal that waits next time arrives.
