Principle of work of the present utility model is:
Earlier put through controlled telephone set with another telephone set or mobile phone.After hearing ring back tone, the 25Hz/90V ringing signal is reservoir capacitance C2 charging behind partiting dc capacitor C1, diode D1, D2 voltage multiplying rectifier, when voltage rises to monostable circuit IC1 6. during pin preset threshold value VTH, its 3. the saltus step of pin outgoing level be low level.The words bell shaken to ring rise to VTH to reservoir capacitance C2 voltage and be defined as T1 during this period of time.At 6. VTH=2/3VCC during foot meridian capacitor ground connection of monostable circuit IC1,5. pin earthing potential device RP of monostable circuit IC1 in this circuit, then VTH is adjusted by RP and determines, generally gets T1=30S.Time delay T1 purpose is set if enough waiting times are arranged when having the people to answer the call; This circuit when six unmanned off-hooks of ring by monostable circuit IC1 3. behind the pin step-down level, the first aerotron T1 conducting, 1 adhesive of first relay J, conversion contact point J1-1, J1-2 closure.Its effect one is that resistance R 6 is connected across telephone wire a, b two ends, and the simulation off-hook stops ringdown; The 2nd, decoding scheme IC3 2. pin inserts speech channel preparation reception dual tone multi-frequency dtmf code, and multi-vibrator IC2 send prompt tone to arrive the calling party simultaneously, and the expression telephone set has been operated in the electrical equipment control pattern, can the acceptor control command.The calling party sends remote control mode " 8888 " dual tone multi-frequency dtmf signal makes C8 send effective low level through the binary-coded decimal of output " 1000 x 4 " after the decoding scheme IC3 decoding after shunt decoding circuit IC4 decoding along separate routes, effectively low level comprises 4 pulses, oppositely discipline 4 and send high level in the back through inverter ic 5, this high level comprises 4 pulses, then through counting machine IC6, the model of its counting machine IC6 is that CC4520 tetrad up counter carries out add-one operation to importing 4 pulses, Q2 sends high potential at counting machine IC6 mouth, thereby finishes password identification.Make the second aerotron T2 conducting through resistance R 12,2 adhesives of second relay J, contact heel J2-1 closure, multi-vibrator IC2 has changed oscillation period because of external capacitor C6, and this moment, the calling party can hear the feedback the tinkle of bells of " tick, tick, tick, tick ".And elevator moves control contact J2-2, J2-3 closure simultaneously, and elevator operation is changed; If do not hear the feedback the tinkle of bells, need to continue to press remote control mode " 8888 ".If surpass 10S, need operation again.
If at this time the calling party does not dial the dual tone multi-frequency dtmf code, or malicious operation, password identification circuit is unassisted, automatic clearing behind the 10S; When the T1 time finished, reservoir capacitance C2 was through 7. pin internal discharge of resistance R 2 and monostable circuit IC1, when reservoir capacitance C2 both end voltage drops to monostable circuit IC1 2. during pin setting threshold threshold voltage VTR, and the 3. pin high level that overturns back.Monostable circuit IC1 3. the pin step-down be defined as T2 during this period of time to what recover high level once more, the time length of T2 is determined by resistance R 2, reservoir capacitance C2 parameter, this circuit T2=10S, and the T2 time is tied postoperative, first relay J 1 discharges, and telephone line recovers normal readiness for action again.
