If Fig. 2～8 are the circuit theory diagrams of the utility model microprocessor, dual-tone multifrequency decoding scheme, GSM modular circuit, IC-card read/write circuit, SIM card connecting circuit, memory circuit, aerial coupling circuit, the technology being well known to the skilled person, does not repeat them here.

User arranges or leaves out the IC-card number that can unblank, the landline telephone that can unblank or phone number all arrange by mobile phone or landline telephone button, the IC-card number that can unblank is set and also must uses supvr's mobile phone with telephone number, input supvr password, method is: user picks up mobile phone or landline telephone is got through the GSM modular circuit in door lock, after twice ring, press #000000##13266516246#, 13266516246 is supvr's mobile phone, the mobile phone that phone number is 13266516246 is simultaneously received note, content is: supvr's mobile phone 13266516246, supvr's password is 000000 at present, please revise supvr's password, press * 000000**234678*, 234678 is new management person password, supvr's mobile phone is received note, content is: supvr's password: 234678, press * 234678**123567*, 123567 is new management person password, the rest may be inferred.When user picks up mobile phone or landline telephone is got through the GSM modular circuit in door lock, after twice ring, while pressing #000000##13266516246#, these push button signallings are exported by the hydraucone of GSM modular circuit, 35 pin 36 pin of CON1 connector, 1 pin through C7 and R4 to U2, 2 pin through C6 and R2 to U2, U2 is a double-tone multi-frequency decoder IC, touch-tone signal can be changed into binary signal, this signal is by the Q1Q2Q3Q4 of U2, export to single-chip microcomputer U1, single-chip microcomputer is received after these binary decoding signals, store corresponding supvr's phone number and supvr's password.

A door lock can arrange at most 500 mobile phones that can open the door or landline telephone, if supvr's password is 123456:

Step 1, gets through with landline telephone or mobile phone after the built-in mobile phone of door lock the inside, hears ring 2 times;

Step 2 can have been unblanked by #123456#*27048329* landline telephone 27048329 these numbers;

Step 3 can have been unblanked by #123456#*13266516246* mobile phone 13266516246;

Step 4 can have been unblanked by this number of #123456#*87048329*87048329;

Step 5 can have been unblanked by #123456#*13966516246*13966516246;

These push button signallings are exported by the hydraucone of GSM circuit, 35 pin 36 pin of CON1 connector, a pin through C7 and R4 to U2,2 pin through C6 and R2 to U2, U2 is a double-tone multi-frequency decoder IC, touch-tone signal can be changed into binary signal, this signal is by Q1, Q2, Q3, the Q4 of U2.Export to single-chip microcomputer U1, single-chip microcomputer is received after these 2 binary decoding signals, is stored the corresponding phone number of unblanking

The IC-card that can unblank is set to be realized by supvr's IC-card is first set, and supvr's IC-card arranges by supvr's mobile phone, method is: use supvr's mobile phone to get through GSM phone in door lock, after 2 rings, press #123456##00#, and then swipe the card once with IC (S50 card) card, hear that hummer " drips " sound, this card has been set to supvr's IC-card, press #123456##00#, these push button signallings are by the hydraucone output of GSM (03), 35 pin 36 pin of CON1 connector, a pin through C7 and R4 to U2, 2 pin through C6 and R2 to U2, U2 is a double-tone multi-frequency decoder IC, touch-tone signal can be changed into binary signal, this signal is by the Q1 of U2, Q2, Q3, Q4 exports to single-chip microcomputer U1, single-chip microcomputer is received after these 2 binary decoding signals, single-chip microcomputer enters and supvr's IC-card is set state is set, single-chip microcomputer enters and supvr's IC-card is set arranges after state, with IC-card, swipe the card once, hear that hummer " drips " sound, this card has been set to supvr's IC-card, IC-card card reader chip (U3) MFRC500, (also can use MFRC520), through inductance L 5, capacitor C 24, C23 connects the socket JK1 of antenna, the carrier signal of output 13.56M, this carrier signal is powered to IC-card, the data-signal of IC-card (modulated signal) is through C22, R13, be coupled to 29 pin of U3, U3 will pass through 13 pin of U3 after modulation signal demodulation, 14 pin are until 17 pin are exported 8 binary signals to single-chip microcomputer U1, U1 stores the card number as supvr using the card number of reading.After using supvr's IC-card to swipe the card once, use other IC-card (S50 card), swipe the card once, this IC-card number stores the storer the inside of single-chip microcomputer (U1) into, this card can have been unblanked, brush continuously different IC-cards, the card number of brushing all stores the storer the inside of single-chip microcomputer into, and these stored card numbers can be unblanked.Use supvr's IC-card to swipe the card continuously after 2 times, use the IC-card that can unblank to swipe the card, the card number of this IC-card is deleted by single-chip microcomputer, and this IC-card can not be unblanked later again.The IC-card that use can be unblanked is swiped the card once, hears hummer " dripping a--" sound, the 5 pin 6 pin 7 pin 8 pin output unlocking signals of single-chip microcomputer U1, and this signal amplifies the winding L 1L2L3L4 of rear drive stepper motor through U4, and door lock is opened by stepper motor.

Due at the utility model IC-card and GSM Remote door lock, be provided with described GSM modular circuit 3 and IC-card read/write circuit 5, therefore, closely time, can unblank by described IC-card read/write circuit 5, when remote, by described GSM modular circuit 3 Remote door locks.

Above described be only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
