Embodiment

See also Fig. 1, shown in Figure 2: the telephone number of putting through this machine by any phone or the mobile phone in any place, ringing signal (25HZ, 90V) through C1 every directly, be added to the input end of IC1 after the R2 current limliting, when ring rings, 4 pin of IC1,5 pin conductings, on 4 pin, just produce a dc pulse signal voltage, through C3, after the R4 filtering, just send into a positive pulse at the CLK of IC2 end, work clock as IC2, this moment, the Q0 end saltus step when the rising edge of first pulse arrives of IC2 was L, and this low saltus step is sent into the left side of IC3NE556 through C18, and NE555 and NE556 all in the native system use as monostable timer.Wherein IC3 is as AUTORESET, the time constant left side is set at 28S, right-hand part is set at 3S, after the 6th ring rings, the Q6 of IC2 is by H → LIC7 upset, the time constant of IC7 also is decided to be 28S, and the Q end of IC7 becomes H to be made R1 and receive telephone wire inlet two ends by T1 driving J1 adhesive, as the load of simulation off-hook.At this moment native system has possessed the ability of utilizing telephone wire to transmit signal.Therefore, this transmission control end utilizes the keyboard of any telephone set or mobile phone can send into various double-audio signals.Directly send into IC4, IC4 (MT8870) is a dtmf decoder, and the double-audio signal of being sent here by transmitting terminal just obtains 12 groups of binary codes at the Q1-Q4 end after IC4 decoding, and the STD end just has a H pulse output (its effect will be spoken of in the back) when whenever sending into one group of signal.We utilize this 12 groups of binary codes to finish various operations just.

For having prevented that the people from deliberately disturbing, the ad hoc encryption section of having counted, here this machine has designed the devices at full hardware structure very dexterously.Can revise repeatedly, do not repeat password and be 212 encryption equipment, and this encryption equipment can also be applied in the miscellaneous equipment.

Encryption equipment is made up of IC8-IC13 etc., and IC8-IC10 is three 6D latch MC14174, IC11 be a slice CD4017 as pulsqe distributor, IC12, IC13 are a pair of volume commonly used, code translator PT2262, PT2272-L4.The principle of work of encryption equipment is: the binary code of being sent here by IC4, MT8870 is directly delivered to the D0-D3 end of IC8-IC10, the STD signal of IC4 is then delivered to the CLK end of IC11, clock signal as IC11, both every group of binary code was added to the D0-D3 end of IC8-IC10 simultaneously, when send the arrival that then will wait for clock signal, the Q1-Q3 of IC11 is connected to the CLK end of IC8-IC10 successively.IC4 is every to send one group of binary code to IC8-IC10, and the STD end is just sent the CLK end of a H level to IC11, and IC11 is under the control of these clock signals, and Q1-Q3 saltus step successively is H.And this signal just MC14174 the D end signal delivered to Q hold needed clock signal.The STD signal is synchronous with binary signal, so whenever sending number key of control end by a telephone set, the Q0-Q3 end of IC4 is with regard to one group of binary code of saltus step, and IC8-IC10 then forwards the D end signal to the Q end one by one and latchs.Promptly eight address end A0-A7 at IC12 have been endowed different values respectively with four data terminal D1-D4 ends.But have only when the TE of IC12 end is L, DOUT just becomes string signal output with the parallel signal of AD mouth.The duty of TE end is controlled by electronic switch T6.When the Q4 of IC11 was H, the C of T6 is L very.At this moment, it is continuous that IC12 will send two polyphones, the serial code signal that content is identical, the overall process of Here it is coding.We are set at 3S with its running time, right-hand part by NE556 is finished, negative edge when trigger pip receives first STD signal Q0 by the H saltus step by IC11 makes its upset by C19, and the H level of 3 pin Q end output provides reset signal by the RET of C14 to IC11 to it.

The running time that is to say password input is 3S, and to bump in 3S password be impossible if do not know to just think the people of password, and Password Operations only allows four times simultaneously, is difficult to find out password for this reason.

Decoded portion is made up of IC13, SW1-SW3, D3-D9, T8 etc., the DT of IC13 is the serial code receiving end, A0-A7 is that end is preset in the address, D1-Q4 is the data initialization end, D3-D9, T8 etc. form NAND gate circuit, when having only preset address sign indicating number as the address code of IC12 input and numeric data code and IC13 identical with numeric data code, the I0 of IC13 holds and just becomes H.As long as and a port is arranged in the anode of D3, D6-D9 is L, the B utmost point of T8 is L also, and C is H very, and IC5 does not overturn, and J2 is failure to actuate, and has only when the anode of D3, D6-D9 all is H, and the B utmost point of T8 just becomes H, and C is L very.Send a trigger pip to IC5, make the IC5 upset by C28, time constant is decided to be 1.8S, and drives the J2 adhesive by electronic switch T7.Utilization is connected on PQ and upward reaches the purpose of controlling peripheral hardware in the contact of J2.When the C of the T8 utmost point becomes L, also send to a reset pulse to the RET of IC8-IC10.Make the IC8-IC10 zero clearing, the Q end all is L, waits for next operation.

The tripod of PQ is the signal sampling input end, can gather the automatically controlled plate 10V of controlled body with interior DC or pulse signal, initial state is that H, L or pulse all can normally receive, and after circuit identification, deliver to the trigger end of corresponding musical film IC17, IC18, make it produce different sound equipments, deliver to the PA port by the contact of C10, C11 and J1, the telephone wire that is sent to the effector by telephone wire is sent in effector's the telephone receiver again, to reach the purpose of replying, this interactive just process.Sampling then is to collect the starting of controlled air conditioner or electric heater or the signal level when stopping.

The principle of work of controlling of sampling circuit is: suppose that the level when managed object is shut down is H, and the T2 conducting, T3 ends, and IC16 keeps ortho states, because be holding state, so there is not music signal output.And triggered by this controller and moment of starting when air conditioner, 3 pin of PQ are by H → L, the pulse negative edge of this low saltus step makes the IC16 3 pin Q output H that overturns trigger IC18 by C12 when IC18 is powered up by C13, the audio voltage of obtaining on pull-up resistor R7 is sent by telephone wire to PA by C10 again, at this moment T2 ends, T3 conducting, the anode of C9 are L, and IC17 does not work because of triggerless.And when shutting down by this controller, 3 pin of PQ are again by L → H, T2 conducting once more at this moment, and T3 ends, and the C utmost point output H of T3 triggers IC17 by C9, and the sound voltage on its load R8 is sent by telephone wire to PA by C11.The process that switching on and shutting down are replied so far is all over.

Otherwise the level when managed object is shut down is L, and T2 ends, the T3 conducting, because the existence of C13 is arranged, IC16 still is in ortho states again, does not therefore at this moment have music signal output.Start moment, 3 pin of PQ are by L → H, and IC16 does not overturn because of being triggered, IC18 also because of not electricly do not work.The T2 conducting, T3 ends, and the C utmost point saltus step of T3 is H, is sent by telephone wire to PA by C9 triggering IC17 and by C11.During shutdown, 3 pin of PQ are again by H → L, and the negative edge of this pulse has triggered IC16, IC18 work equally, and music signal is sent.At this moment T2 ends, the T3 conducting, and the C of T3 is L very, and IC17 does not work because of can not get trigger pip yet.

If what 3 pin of PQ3 were obtained is pulse signal, when the moment by H → L, T2 ends, IC16 upset, the IC18 work that is triggered.The high level of the 3 pin Q of IC16 output simultaneously is added to the B utmost point of T3 through D10, R34, again because the same 28S that is all of time constant of IC16 with IC7, this is full time of this controller just also, therefore, T3 will be in conducting state always at this moment, the C utmost point of T3 is L always, so IC17 can not work.Generally speaking, the duration of pulse in air-conditioning when start be 20S (on the indoor set as the green LED of power light flash with one second frequency just remain on Chang Liang after ten times state up to shutdown).
