Fig. 2 the utility model receiver architecture schematic diagram.

See Fig. 1, press singly-bound K ₁, the power supply of entire circuit connects, C ₅, R ₇Constitute a differential circuit, capacitor C ₅Charging, resistance R ₇On a spike is arranged, no matter this moment is IC ' ₂Be in which kind of state, differential circuit C ₅, R ₇Give IC ₂Reset IC ₁NOR gate A, B constitute the signal of pulse generator through NOR gate C input IC ₂' the CP terminal, this moment IC ₂' enter count status, when data during from binary " 0000 " to " 1011 ", Q ₄, Q ₂, Q ₁Export high level respectively, R ₆On do not have electric current to flow through, R ₆Two ends are high level, are input to NOR gate C locking, IC ₂' CP end do not have pulse signal, counter to stop counting, data are kept, wherein IC ₂' CP terminal and T ₁' the deviator resistance R ₂Link to each other.

See that Fig. 2 receiver operation process of the present utility model is as follows:

From L ₁' the induction of high frequency signal is through C ₁' send T behind the circuit tuning ₁' base stage b, collector electrode C carries out superregenerative detection, the signal of output is through C ₃' be coupled to OP ₁, OP ₂Carry out homophase and amplify, through C ₅', R ₇' filtering, be sent to OP again ₃, R ₁₄The Schmidt trigger that constitutes is shaped to the standard square wave, and this square-wave signal one tunnel removes IC ₃The CP terminal, the F that triggers is removed on another road ₁, F ₂But the monostable trigger-action circuit of the repeated trigger that constitutes, the monostable circuit that is triggered is through F ₃Become low level, a row pulse signal passes through F ₃Export a positive transition signal and trigger F again ₄, F ₅The monostable trigger-action circuit that constitutes is through F ₅The output high level, D ₆～D ₁₀Constitute the decoding circuit of binary number 1011, if enter IC ₃Pulse number be 11, decoding circuit just has a pulse and outputs to IC ₅OP end, treat temporarily steady time one mistake, F ₅Output low level is blocked the output of decoding circuit, simultaneously F ₆The output high level is through C ₁₂Charging obtains a spike makes IC ₃Reset, for next spike train input is prepared, when one shows 11 pulse inputs, decoding circuit just has a pulse output, be greater than or less than the pulse input of this numerical value, decoding circuit does not all have pulse output, has so just finished the decrypting process of a digital signal yet.Along with IC ₅Pulse signal input, Q ₁～Q ₉High level can appear successively, when greater than 9 pulse inputs, and transistor T ₃Collector electrode be in high potential with IC ₅CP end pin the inhibit signal input.See Fig. 2, monostable circuit F ₁, F ₂After the upset, F ₃Output low level is simultaneously F ₇, F ₈Trigger.By F ₇, F ₈The monostable circuit that constitutes compares F flip-flop transition ₁, F ₂The monostable trigger-action circuit time is long a lot.F ₃F behind the output pulse signal ₈Export a positive transition, through capacitor C ₁₄Coupling removes to trigger F ₉, F ₁₀Monostable trigger-action circuit.F ₁₀The output high potential is opening with door A～H, as if IC this moment ₅Q ₂Be high level, hold with regard to the CK that the instruction that a high level is arranged outputs to second JK flip-flop, work as F with door B ₉, F ₁₀Temporarily steady time one mistake of monostable trigger-action circuit, F ₁₀Become low level again pinning from high level at once, simultaneously F with door A～H ₁₁The output high level is given IC ₅Reset, wait for IC next time ₅CP end signal input, with the output of door B from the high level to the low level, rely on JK flip-flop that instruction is memorized.By triode T ₅Drive the controllable silicon DZ of actuator ₂Open, the electrical appliance for the second tunnel provides power supply.

Embodiment 2. the utility model receivers have eight tunnel power channel, install on the remote circuit controller on the Box Cover of eight the independent current source plug-in units and the eight pairs of power-line terminals, receiver eight channel status indicator LED1～LED8 are housed, nine contact witches, wherein there is one to be the total stopcock of power supply, DZ ₁～DZ ₈Be bidirectional triode thyristor, can be expanded into eight paths.Work as IC ₅(CD4017) with pulse of the every output of door, IC ₅Q ₀～Q ₉High level appears in end successively, eight of data outputs " with " goalkeeper Q ₁～Q ₈Signal pin and can not directly go to control eight JK flip-flop, must signal output be arranged CP saltus step side, so just control each JK flip-flop state arbitrarily, promptly control the on off operating mode of 220 volts of power supplys of each passage arbitrarily.Whenever by a remote-control transmitting key K ₁, " with " door just has pulse output, IC ₅Q ₀～Q ₉Displacement from low to high.Stopped key for 2 seconds, the number of times that circuit be pressed before just confirming to be somebody's turn to do at this moment is when pressing 9 teleswitch K continuously ₁The time, because " R " of eight JF triggers end is all at IC ₅(CD4017) Q ₉On the end, so the power supply of eight passages is all turned off.
