5,6,7,8,9 further describe the circuit structure of the present utility model and the course of work with reference to the accompanying drawings

Phase inverter F1, F2 and R14, C20 forms a multivibrator, its output audio square wave is anti-phase through phase inverter F3, through R13, the emitting diode that VT8 and current-limiting resistance R11 drive among the integrated infrared emission reception VT7 sends modulated infrared, after the human body reflection, to produce a faint light electric current that changes with modulated square wave in the infrared receiving tube in VT7, this electric current produces pressure drop on R12, through C24, R24 is coupled and is amplified to VT16, trigger the monostable circuit that IC3a forms, make IC3a output high level just the relevant circuit of main frame enter duty and finish host-initiated.

When the people knocks at the door, HID1 picks up this vibration signal, after amplifying, the amplifying circuit that VT15, VT16 etc. form triggers IC3a, start main frame and enter duty, behind the host-initiated, started working by the bistable circuit that IC3b and peripheral cell thereof are formed, it is output as high level, make VT19 base stage shorted to earth by VT18, close the circuit of forming by VT19 and peripheral cell.Through behind the certain hour, the bistable circuit state turnover, the IC3b output low level, at this moment switching tube VT18 ends, high-frequency oscillating circuits is started working, and L4, R15, C34 coupling circuit are fed to the VT19 base stage with the output square wave of F3, to higher-order of oscillation amplitude modulation, launch by the radio wave of amplitude modulation from antenna TX3, i.e. the handset starting signal.Because of bistable circuit IC3b output state punctuated turning over, so the handset starting signal is intermittent emission.

The Armstrong circuit of forming by VT1 and peripheral cell thereof, after receiving the handset starting signal, detecting action demodulation output modulated square wave signal by circuit self, amplifying circuit through VT2 and peripheral cell composition amplifies, and pass through C10, C11, VD1, the VD2 voltage multiplying rectifier, export a direct-current control voltage, control VT3, VT4, R7, the on-off circuit conducting that R8 forms provides the working power of encoder IC1 and high-frequency generator VT5, encoder is by IC1, R9 forms, different conditions by the IC1 address wire is encoded, the code signal of its output carries out amplitude modulation to VT5 and peripheral cell composition oscillating circuit thereof, high-frequency signal after the amplitude modulation amplifies through the high-frequency power amplifying circuit of compositions such as VT6, is sent the radio wave that has the cell phone password signal by antenna TX2.Here it is modulation signals.Because the emission of handset starting signal break is so modulation signals also is an intermittent transmission.

After the Armstrong circuit of being made up of VT20 and peripheral cell thereof is received modulation signals, detecting action by receiving circuit self, the demodulation outupt coded signal, the voltage amplifier of forming through VT21, VT22 etc. amplifies, be coupled to the input of decoder IC4, the password of representing when code signal conform to the password of IC4 (be encoder. the state of the corresponding address wire of decoder is identical) time encoder output high level control voltage, drive Electromagnetic lock coil L7 by R45, VT23, thereby open door lock.Because of modulation signals is an intermittent transmission, thus unlocking action also synchronously repeat, till opening door lock, in case can not once unblank because of other reason causes.

After door was opened, the K3 closure resetted monostable circuit by force by on-off circuit VT17 etc., IC3a output output low level, and the relevant circuit of main frame quits work.Main frame comes back to wait state.If messenger is not owner, though he can start main frame, can not unblank, through monostable circuit is from horizontal reset after the of short duration time-delay, the relevant circuit of main frame is closed voluntarily.

Behind the mains failure, by battery E2 to main frame for low-tension supply, press during the inverter circuit of being made up of VT11, VT12, VT13, VT14, B3 becomes the transformation of electrical energy of E2 simultaneously and after VD9, VD10, VD11, VD12 rectification, be stored among the C22 usefulness that the confession tapered end is unblanked.The inverter driving signal provides after F3, F4 are anti-phase for the output square wave of F2.

Because the handset starting letter is different with the transmitting power of modulation signals, thereby operating distance is also different, and the former operating distance is also little, and latter's operating distance is also big.When owner indoor, have the guest visiting and after starting main frame, the uncontrollable operating handset of handset starting signal, owner, shakes control and opens the door by mobile phone button K1 launching code modulation signal indoor.Guest's startup main frame that stands in front of the door or knock at the door, Music Clip IC5 work, and send the doorbell music by sounding component HTD2, and playing the effect of button-free doorbell, this function can be controlled by K switch 4.
