Below the duty of this intelligent cipher lock is described in detail:

(1) SM set mode: as shown in Figure 3, intelligent cipher lock was in and waited to open and treat closed condition this moment, and shift fork 23 is positioned at the normal position.

(2) lock: by closing button SB1 input signal on the remote-control key 1, after rolling code chip IC 1 processing able to programme, launch by high frequency transmission circuit, the receiving circuit II of door lock control device 2 receives signal, be input to programmable single chip computer IC8 after treatment, single-chip microcomputer IC8 reads, the decoding back is from the 8th pin output control signal, make the triode N8 conducting of drive circuit III, the positive pole of motor 12 and positive source are connected, motor 12 is in just to change a job makes state, this moment, motor shaft drove the allocating slot that shift fork 23 is rotated into bogie 16, overcome the torsion of clamp reduction torsion spring 15, promote clamp 18 and do radial motion, the front bayonet slot of clamp 18 breaks away from alignment pin 17 makes bogie 16 do the axially-movable of advancing, and drives in the locking bar 14 insertion lock box devices 8, and then the bar fork of shift fork 23 breaks away from the allocating slot of bogie 16, this moment is under the twisting force of clamp reduction torsion spring 15, the back draw-in groove of clamp 18 snaps in alignment pin 17 lock drive framves 16 and locking bar 14, and this lock is in the state of locking, as shown in Figure 4.Simultaneously, programmable single chip computer IC8 is from the output control signal, timer internal work is automatic shutoff signal output after 2 seconds, make motor 12 outages, then export control signal by the 9th pin of programmable single-chip microcomputer IC8 again, make the triode N9 conducting of drive circuit III, motor 12 reverse getting electric 0.3 second are with shift fork 23 returns.

Under locking state, if there is the thief to destroy cover cap 7, search switch 6 will be disconnected, programmable single chip computer IC8 the 6th pin receives signal, operation below carrying out after internal processes is handled:

A) drive warning circuit IV by the 4th pin output signal and produce alarm sound, afterwards if the thief continues to destroy lock body, the vibration that produces will make the vibration inductor L5 of vibration induction circuit V produce amplitude signal output, after IC5A and IC5B and capacitor, resistance shaping are amplified, be input to the 20th pin of programmable single chip computer IC8, after routine processes, drive warning circuit IV and produce alarm sound by the 4th pin output signal.

B) simultaneously, export the triode N8 conducting that control signal makes drive circuit III by the 8th pin, motor 12 gets electric just the commentaries on classics 1 second, promptly drive shift fork 23 rotations, make shift fork 23 withstand the block of being located at bogie 16 afterbodys, make the thief can't open lockset the lock core locking, as shown in Figure 6.

If the thief destroys behind the cover cap 7 again with search switch 6 closures, the vibration alarming function is still remained valid, and shift fork 23 still withstands the block of being located at bogie 16 afterbodys, has only by the start button of remote-control key 1 and carries out open function, can recover normal operating conditions.If but search switch 6 is not placed closure before or after opening, after press close key and carrying out function, will automatically perform above-mentioned a), b) the item function.

(3) unblank: press the unlatching button SB2 input signal on the remote-control key 1, after rolling code chip IC 1 processing able to programme, launch by high frequency transmission circuit, the receiving circuit II of door lock control device 2 receives signal, be input to programmable single chip computer IC8 after treatment, single-chip microcomputer IC8 reads, the decoding back is from the 9th pin output control signal, make the triode N9 conducting of drive circuit III, the positive pole of motor 12 and power cathode are connected, motor 12 is in the counter-rotating duty, this moment, motor shaft drove the allocating slot that shift fork 23 is rotated into bogie 16, overcome the torsion of clamp reduction torsion spring 15, promote clamp 18 and do radial motion, the back draw-in groove of clamp 18 breaks away from alignment pin 17 makes bogie 16 do the axially-movable that retreats, drive locking bar 14 and withdraw from lock uint 8, the short fork of shift fork 23 breaks away from the allocating slot of bogie 16, this moment is under the twisting force of clamp reduction torsion spring 15, the front bayonet slot of clamp 18 snaps in alignment pin 17 lock drive framves 16 and locking bar 14, shift fork 23 rotates and makes its bar fork move pull bar 21 to stop, overcome the elastic force of dead bolt reseting pressuring spring 22, drive activity dead bolt 20 is to lower dead center, this lock is in the state of unlatching, as shown in Figure 5.Simultaneously, programmable single chip computer IC8 is from the output control signal, timer internal work is shutoff signal output after 4 seconds, make motor 12 outage after 6 seconds, again by the 8th pin output control signal drive circuit III of programmable single chip computer IC8 triode N8 conducting, motor 12 just changeing electric 0.3 second, with shift fork 23 returns, reset movable dead bolt 20 this moment under the elastic force effect of dead bolt reseting pressuring spring 22, gets back to SM set mode.

When the user loses remote-control key 1 or thinks that data are dangerous, can receive data to remote control and format and refresh, make and lose remote-control key 1 and can not open this door lock.The format method for refreshing is as follows: press the button the SB4 button and make its closure, D9 extinguishes up to light emitting diode, and release button SB4 has promptly carried out format by 7 couples of programmable single chip computer IC8 of IC and handled.Then, press the button SB4 again and made unclamp in its closed 1 second, and then press any button on the remote-control key 1, this moment, programmable single chip computer IC8 received output signal, and the reception data after upgrading are confirmed, had realized Refresh Data.

When intelligent cipher lock generation fault or standby electric power exhaust, can not pass through remote-control key 1 open and close door lock, can pull down cover cap 7, insert mechanical lock 11, promote bogies 16 open and close door locks with standby spring key by lock core shift fork 25.

When on the rotary shell 13 lock device 19 time, promptly the movable dead bolt 20 of lockable can not be opened, and reaches indoor purpose of locking, device 19 is locked in reverse rotation, the torsion of the reduction torsion spring by locking device 19 returns to SM set mode.
