Fig. 3, Fig. 4 amplifies for receiving, decoding, the decoded signal that this circuit of control circuit (2) is made up of FM reception integrated circuit block (IC1) and peripheral cell etc. receives amplifying circuit (8), 5 audio coding integrated circuit block (IC2, IC3, IC4, IC5, IC6) etc. stepping decoding and the decoded signal output circuit (9) formed, 4 triode (VT3, VT4, VT5, VT6) forming stepping decoder power control circuit (10) is the power supply circuits of decoder, 4 triode (VT7, VT8, VT9, the power supply holding circuit of forming such as VT10), 5 concatenation type encoded control signal output apparatus (11) that the triode serial connection forms, 4 triode (VT12, VT13, VT14, VT20) and the control executive circuit (13) of bidirectional triode thyristor compositions such as (VS2) be power consumption equipment (S) power on-off control circuit, diode (D16, D17, D18, D19, D20) with electric capacity (C49, C50, C51) and the power circuit (12) formed of resistance (R44) be rectification filtering power circuit and wait until by the decoding circuit power supply self-insurance delay switching circuit that triode (VT11) etc. is formed and to form.FM reception integrated circuit block (IC1) adopts the TDA7010 integrated circuit block.

As shown in Figure 4 after external power is connected; by diode (D16; D17; D18; D19; D20) with electric capacity (C49; C50; C51) and the power circuit (12) formed of resistance (R44) be rectification; filtering; voltage stabilizing circuit provides about 6 a volts D.C. regulated power supply for entire circuit; though at this moment entire circuit has been in holding state; but the power consumption circuit only receives amplifying circuit (8) by the decoded signal that FM reception integrated circuit block (IC1) and peripheral cell etc. are formed; the audio coding integrated circuit block (IC2) of decoding circuit and the decoding circuit power supply self-insurance delay switching circuit of forming by triode (VT11) etc.; other all not power consumption of circuit; and audio coding integrated circuit block IC3; IC4; IC5; IC6 then is in stopped status fully, and this state is no matter the sets of numbers figure place all is like this when being several.Receive before amplification, decoding, control circuit (2) the input operate as normal, can be under the supervision of special equipment, also can be under the cooperation of encoding transmitting circuit (1), 5 audio coding integrated circuit blocks (IC2, IC3, IC4, IC5, IC6) all are arranged to any one number among the 0-9 in the encoding transmitting circuit (1) respectively sequentially, and 5 set numbers of such 5 audio coding integrated circuit blocks (IC2, IC3, IC4, IC5, IC6) link together and have just formed one group of complete decoding control circuit with 5 item sign indicating numbers.At this moment just have only set number of number that encoding transmitting circuit (1) sent and decoding circuit and coded sequence and decoding order, when figure place is in full accord, power on-off control circuit could move, reach the purpose of remote control switch, otherwise control circuit will not worked.When receiving amplification circuit piece (IC1), the decoded signal that receives amplifying circuit (8) receives the code signal that encoding transmitting circuit (1) sends, and through triode (VT1, VT2) after the amplification, send into 5 audio coding integrated circuit block (IC2 in stepping decoding and the decoded signal output circuit (9) respectively, IC3, IC4, IC5, IC6) input 3 pin are deciphered, when first coding number is consistent with first decoding number, decoding circuit promptly enters operating state, first decoding audio decoder ic piece IC2 the 8th pin is output low level, the diode D2 that be serially connected between the 8th pin and the resistance R 18 this moment is a high level because of anode, negative terminal is low level and conducting, triode VT15 base current is through resistance R 18, diode D2 flow to audio coding integrated circuit block IC2 the 8th pin, cause triode VT15 base stage also to present a low level and conducting, positive current flows to collector electrode through triode VT15 emitter, makes collector electrode be high potential.At this moment triode VT15 collector current divides three tunnel outputs: the one tunnel flows to triode VT7 base stage through resistance R 27, make its in the extremely short time rapidly conducting and triode VT15 form a power supply holding circuit, make the self-insurance of this group power supply.One road triode VT16 emitter of flowing through is for the power supply circuits of level power supply self-insurance and the audio coding integrated circuit block IC3 of subordinate are down made power supply.This power supply is again the control signal of control circuit simultaneously, and this power supply is transmitted backward by power supply holding circuit one-level one-level.Another Lu Zejing resistance R 23 is sent into triode VT3 base stage, before first code signal does not stop emission, diode D1 makes triode VT3 base voltage almost nil because of being conducting state, so the time, although triode VT3 base stage has a forward voltage to arrive, still can not conducting because of the reason of diode D1, therefore power supply also can not arrive the audio coding integrated circuit block IC3 of subordinate's decoding circuit, although the yet existing decoded signal input of IC3 is not because of there being the forward power supply not work yet.After first code signal stops emission, audio coding integrated circuit block IC2 the 8th pin of first decoding recovers high level, diode D1 ends because of back-pressure, and triode VT3 conducting is for audio coding integrated circuit block IC3 provides a forward power supply, makes IC3 get electric and enters holding state.Meanwhile, some arrives the 6th pin of audio coding integrated circuit block IC2 to the positive supply that VT3 provides through resistance R 9, diode D20 in addition, add a high potential for IC2 the 6th pin, force its failure of oscillation, reach the limited purpose of higher level, like this, when second decoded signal arrives, even and first be jack per line, also have only second decoding audio decoder ic piece IC can operate as normal, at first decoded signal is reacted, having avoided working simultaneously because of the superior and the subordinate is interfered.When second decoded signal sent into decoding circuit, audio coding integrated circuit block IC3 repeats the course of work of IC2, below at different levels all be so (number repeated code or not all is the same) when to the last a code signal arrived, the control signal that triode VT19 collector electrode is exported just can make ON-OFF control circuit work.

Above circuit when work (referring to decoding circuit, power supply circuits, power supply holding circuit etc.) power supply hold time and be subjected to the influence and the control of the delay switching circuit that triode VT11 etc. forms, after power connection, positive supply promptly charges to capacitor C 45 through resistance R 36, when capacitor C 45 both end voltage reach a certain height, triode VT11 promptly is switched on, and triode VT7 base stage is shorted to ground through diode D14.At this moment, if when audio coding integrated circuit block IC2 input had respective coding signal input, the 8th pin was an output low level, diode D2 also is switched on simultaneously, the voltage at capacitor C 45 two ends is released through diode D2 negative terminal, and triode VT11 base stage is ended because of losing forward voltage.At this moment as long as this code signal does not interrupt, audio coding integrated circuit block IC2 the 8th pin just can not recover high level, and triode VT11 also incites somebody to action remain off state always.After above code signal stops emission, audio coding integrated circuit block IC2 the 8th pin recovers high level immediately, diode D2 promptly ends after the back-pressure because of occurring, resistance R 36 begins again to capacitor C 45 chargings, VT11 is switched on up to triode, triode VT7 ends, and circuit returns to initial condition again.If at triode VT11 not before the conducting, encoding transmitting circuit (1) is sent next corresponding code signal here, make also output low level of audio coding integrated circuit block IC3 the 8th pin, at this moment, diode D6 will release the voltage at capacitor C 45 two ends once more, so just guaranteed not reason decompression and ending of triode VT7 base stage, guaranteed that also positive supply that triode VT15 collector electrode is exported is not interrupted and continues to pass toward next stage.

This shows, as long as encoding transmitting circuit (1) is after sending a number, launch next number at delay switching circuit in set time, distribute up to one group of corresponding number, the work decoding of stepping decoding and decoded signal output circuit (9) the just work of energy one-level one-level goes down, the encoded control signal just can hand on to the one-level one-level, be activated up to control executive circuit (13), even otherwise last item sign indicating number does not send on time, the number of front just will be scrapped, and circuit will return to holding state in the time that is provided with.Change the resistance of resistance R 35, R36, the time can change between 1 second to 36 seconds in limited time, and this circuit time of prescribing a time limit was made as 4 seconds.The encoded control signal arrives control executive circuit (13) after triode VT19 output: the one tunnel arrives triode VT13 through resistance R 38, though this moment, triode VT13 was switched on, to be in cut-off state inoperative because of triode VT14.Another Lu Zejing resistance R 37, diode D15 arrive triode VT12 base stage, make triode VT12 and triode VT20 be combined into another power supply holding circuit under the effect of resistance R 42, for bidirectional triode thyristor (VS2) and triode VT14 provide power supply.The power supply that triode VT20 collector electrode is exported, a part is sent into bidirectional triode thyristor (VS2) the control utmost point after resistance R 43 current limlitings, make its triggering and conducting, make electrical appliance (S) electric and work.Another part is then sent to capacitor C 47 anodes through resistance R 39, gives capacitor C 47 chargings, and makes triode VT14 conducting within a certain period of time, for power cutoff is prepared.The ON time of triode VT14 is 2 seconds in the present embodiment.When triode VT19 exports the encoded control signal for the second time (after 2 seconds), triode VT14 is switched on, become passage between triode VT13 emitter and the triode VT14 collector electrode, when the encoded control signal when resistance R 38 is sent into triode VT13 base stage once more, triode VT12 base voltage is promptly by triode VT13, VT14 is shorted to ground, triode VT12 ends immediately, triode VT20 collector voltage is also with being zero, bidirectional triode thyristor (VS2) also ends because of losing trigger voltage, electrical appliance (S) power supply is turned off simultaneously, and the switching programme of circuit promptly comes to an end.The same sets of numbers of this circuit by once for opening, again by once being the pass.

The utlity model has following outstanding feature:

1, when the decoding circuit number is provided with, fully repeated code as: 00000,11111 ..., all numbers all can repeat fully in a sets of numbers and not influence its security performance.

2, the decoding order is undertaken by the coding figure place fully, even fully during repeated code, the figure place of coding can not be lacked one, be unlike in when using binary ciruit decoding can omit for No. 0 not according to, so just make this circuit improve its secrecy and interference free performance greatly, increased the scope that is provided with of number.

3, decoding circuit stepping worker mode: promptly enter operating state from front to back step by step, the state of deactivating step by step from front to back makes decoding circuit be in the cell operation state, has avoided the interference that causes when working simultaneously because of other element circuit.
