As shown in Figure 1, outside telephone stations 4 links with indoor electric phone 2 and controller of the present utility model 1 by the telephone exchange 3 of telecommunication bureau, and controller 1 is connected on the pair of telephone lines together with indoor electric phone 2.Several electric equipments 10 link by wiring and this controller, outside telephone stations 4 is when 2 dialing of indoor electric phone, telecommunication bureau's switch 3 sends the ringing pulse signal to indoor electric phone 2, controller 1 receives this signal simultaneously with indoor electric phone 2, and via controller 1 is handled the also unlatching or the shutoff realization Long-distance Control of the mains switch of control apparatus equipment 10.
As shown in Figure 3, electrical equipment remote controllers of the present utility model comprise casing 5, the terminals 6 of connecting circuit equipment are housed on the casing 5, in order to show electric equipment slave mode indicating device 8(such as luminous tube), connect the terminals 7 of telephone wire, the control circuit part is housed in the casing 5.
As shown in Figure 2, control circuit partly comprises:
By photoelectrical coupler 11, pulse-scaling circuit 12, delay circuit 13, drive the automatic simulation circuit for answering that executive circuit 14 and analog telephone 15 are formed;
The cipher control circuit of forming by change-over circuit 21, decoding circuit 22, cryptochannel 23, delay circuit 24 and Drive and Control Circuit 25;
Be provided with the switch J that is subjected to drive control circuit in controlled electric equipment 10 power supply circuits
A-1～J
D-1(as shown in Figure 5).
Dial when being indoor phone number when outside phone, 3 beginnings of telecommunication bureau's switching equipment send the ringing pulse signals to indoor electric phone 2, and frequency is that 16-25Hz, voltage are about 90V, and indoor phone 2 and this controller 1 receive this pulse signal simultaneously.Photoelectrical coupler 11 is coupled to pulse-scaling circuit 12 countings with the ringing pulse signal, after running up to the pulse of setting number (such as 6), drive executive circuit 14 through delay circuit 13 conductings, the analog telephone machine circuit 15 that connection is made up of resistance and coil produces simulation off-hook effect, telecommunication bureau's switching equipment 3 promptly gives outside phone with connection signal, stops ring.Because delay circuit 13 stops to simulate off hook state after delaying time through setting-up time (as 10 seconds), telecommunication bureau's switching equipment 3 gives outside phone 2 blind sounds.Therefore, below said password and control code must in setting-up time (as 10 seconds), transfer to, promptly before stopping to simulate off-hook, transfer to just effectively.

A1～J
D1(as Fig. 5) is in controllable state.At this moment, outside telephone stations 4 is transferred to predefined control code again, just can open or turn-off the power circuit of corresponding electric equipment.In order to prevent stranger's malicious sabotage, improve safety factor, be provided with pseudo-cryptochannel in the circuit of the present utility model.If in the input cryptographic processes, dialled the number outside the password, also claim pseudo-code, the high level of BCD decoding circuit 22 outputs will make the password counter O reset, be returned to the password state before of not dialling.
Shown in Fig. 4,5, in this controller: pulse-scaling circuit 12 is taked integrated circuit CD4017, and photoelectrical coupler 11 is taked photoelectrical coupler PS2002B, and change-over circuit 21 is taked integrated circuit MC145436; Decoding circuit 22 is integrated circuit CD4514; Cryptochannel is taked integrated circuit CD4017; The ringing pulse signal is through capacitor C 1, resistance R 1 step-down, by making photoelectrical coupler 11(BG4 after bridge circuit (BG3) conversion) conducting, the CP end input count pulse of pulse-scaling circuit 12, adopt the rising edge of a pulse flip-flop number by Y6 port output high level, through triode (BG21) the turn-on relay J2 in the time-delay rear drive executive circuit 14, can make counter O reset (Y6 is a low level), go up at lead-in wire terminal L1, L2 port (being terminals 7) again and insert analog telephone (J2-1 closure, coil L and resistance R 2 insert), ring is stopped.The time of relay J 2 adhesives is depended on by resistance R between gate circuit IC2A, IC3A 6 and capacitor C 4, this circuit design is 8 seconds, this needs to finish the cipher control operation after showing closing of the circuit in 8 second time, otherwise after monostable trigger-action circuit pulse disappearance, triode (BG21) ends, relay J 2 discharges immediately, and telecommunication bureau will give blind sound and handle; After the J2 adhesive, controlling party is that available touch-tone signal sends cipher control, earlier by 4 passwords, and then by control code; From 7 pin of change-over circuit 21 input dtmf signal, at 2,1,13,14 ends output binary-coded decimal, clock frequency is 3,5,8MHZ, decoding circuit 22 input binary-coded decimals, output high level; The password of supposing this machine is made as " 3,6,9,0 ".Behind first password, at decoding circuit 22(CD4514) port Y3 output high level, because not adhesive of J1, the J1-1 normally opened contact still is an off-state, the circuit access failure of triode BG5-12, each relay J A-D can not get supply voltage and can not inhale promptly uncontrolled before the password input is finished.But the C end multiple connection of triode BG13 in Y3 end and the cryptochannel 23, cryptochannel 23(CD4017), has the function that powers on from zero clearing, default initial state Y0=1, like this, dialled after " 3 ", provide base voltage to BG13, from the high level of BG13 collector electrode output through R18, the R19 dividing potential drop is after gate circuit IC3C, IC3D, be added to the Cp end counting of cryptochannel 23, and at Y1 end output high level, because the base voltage of the Y1 end institute triode that connects (BG14) must be by decoding circuit 22(IC5) the Y6 end provide, just can make IC6 continue to count so controlling party must be dialled " 6 " again after dialling " 3 ".By that analogy, pressing password " 3; 6; 9; 0 " after, at cryptochannel 23(IC6) port Y4 output high level, at this moment one tunnel process capacitor C 6 makes the IC6 zero clearing, another road enters by IC circuit 2B by capacitor C 7, IC3B, resistance R 21, (the stable state time is by R21 temporarily for the monostable trigger-action circuit that capacitor C 9 is formed, the C9 decision), the triode of conducting Drive and Control Circuit 25 (BG18), make relay J 1 adhesive, the J1-1 normally opened contact becomes closure state, voltage is provided for triode BG5-12 and each relay J A-D, make it be in controllable state, this moment, outside telephone stations can be dialled control code, for example dialled " 3 ", at the Y3 of IC5 port output high level, triode BG7 conducting, relay J B energising, corresponding JB-1(Fig. 5) adhesive, behind certain hour (10 seconds), relay J 1 is discharged automatically, cut off the corresponding power supply circuits of BG5-12 and relay J A-D, make it uncontrolled.If dialled the number outside the password (pseudo-code) in the input cryptographic processes, the high level of decoding circuit 22 outputs will make the password counter O reset, be returned to the password state before of not dialling.For example dial " 4 ", the Y4 port output high level of IC5, through d point, diode D3, R23 dividing potential drop, conducting BG17 output high level makes the IC6 zero clearing, is returned to and does not dial the preceding reset condition of password.
BG20 in the power circuit is a voltage-stabilizing device; J
A-DBe the MSL-415B relay.In the described delay circuit or the door IC2 take integrated circuit CD4001, Shi Mite IC circuit 3 is taked integrated circuit CD40106.
