Master controller of the present invention and slave controller can design with the integrated circuit of extensive (LSI) and ultra-large (VLSI), the circuit structure compactness, and the reliability height meets telecommunication apparatus and inserts code requirement.
Please continue with reference to shown in Figure 5, the existing course of work and operation principle with Remote Automatic Control System of the present invention is summarized as follows:
When calling out with master controller 50 at arbitrary Dual Tone Multifrequency phone, the calling subscriber is connected to convertor user line (a, during phone b), stored-program control exchange is to called ringing-signal feeding, micro-control unit (MCU) 54 detects the ring back tone detection output signal that processing capacity part (U5, U7) provides according to the signalling tone in the signalling tone detection/simulation dislodging machine circuit module 57, begin it is carried out Ring-down count, or the startup timer begins regularly.In the ringing number of setting or in the time limit of setting, if called subscriber's off-hook (with master controller 50 mutually and the phone that connects), then the calling subscriber carries out normal voice call with the called subscriber and communicates by letter, 50 pairs of Speech Communications of master controller have no effect.
If in the ringing number of setting or in the time limit of setting, the unmanned off-hook of called subscriber is replied, then the MCU54 in the master controller 50 will simulate artificial off-hook and start interactive voice circuit module 53 (U6) and send " please input password " voice suggestion to the calling subscriber.The calling subscriber operates according to voice suggestion, and its input operation information receives laggard row decoding through Dual Tone Multifrequency decoding circuit module 52 (U1), and gives MCU54 and carry out judgment processing.If the calling subscriber inputs the password mistake and reaches the errors number of setting, then master controller 50 will be simulated artificial on-hook.If it is correct that the calling subscriber inputs password, then master controller 50 starts the voice suggestion that interactive voice circuit module 53 (U6) send " please select electric equipment ", as 1-illumination, 2-air-conditioning, 3-electric rice cooker, 4-water heater or the like.After the calling subscriber correctly selected to import electric equipment, master controller 50 started the voice suggestion that interactive voice circuit module 53 (U6) send " please import the open and close operation ", and as the 1-turn on, 0-closes electrical equipment.Master controller 50 receive through after Dual Tone Multifrequency decoding circuit module 52 (U1) decoding electric equipment is carried out correct open and close operational order after, it is high and low level that MCU54 just exports the open and close control signal, this high and low level signal in master controller 50 encoder 552 (U3) and modulator 551 (U2) modulation after launch.After the demodulator 61 (U1) of wireless signal in slave controller 60 separated mediation decoder 62 (U2) decoding; export to relay 65 (K1 ... K6); thereby electric equipment is carried out corresponding open and close control; and photoisolator 64 (U3 ... U8) demodulator 61, decoder 62 are kept apart with electric equipment photoelectricity, provide protection the light current circuit in the electric equipment.
In order to realize that call can implement the open and close of many electric equipments control, master controller 50 again through interactive voice circuit module 53 (U6) to the calling subscriber send " continuing to control other electrical equipment? " voice suggestion, be that 0-is not as 1-.If then repeat said process, just the electric equipment difference; If not, then calling subscriber's remote auto control operation this time finishes.
