Fig. 4 is stored among the EEPROM22 in order to handle the control program flow chart according to microprocessor 24 of the present invention.Pushing power switch button 5, power circuit 25 starts, so that begin to control circuit 20 power supplies, microprocessor 24 is started working (step 60) behind pressing button 4, microprocessor 24 is read the signal of signal (step 62) the keyboard input of keyboard 10 inputs and will be spoken of below, it can be one group of digital signal or a unlocking signal, a code signal or a locking signal, if operation CL3 then can import reset signal.Subsequent, microprocessor 24 determines whether mark 1 sets (step 64), when lockset is in opening, be mark 1 not to be set or mark 1 resets, if lockset when being in locking states, just is provided with mark 1, then microprocessor with the signal of input be stored in M among the EEPROM23
1The lock cipher of cellular zone compares (step 66).If result relatively is suitable, then microprocessor just jumps to step 70, and in step 70, microprocessor exciting electric 31 rotates, and connects green LED 8(step 72).Drive pins 40 and forward the A point to from the B point when the rotation of motor 31 makes gear 38 rotate 180 °, when lockset was unlocked, microprocessor makes motor 31 stop (step 74), and was subsequent, and microprocessor just makes mark 1 reset or removes this mark 1(step 76).Then, according in below with the reason of speaking of, microprocessor makes counter reset or sets counter and equals " 0 " (step 78).After this, microprocessor will be in wait state (step 99); Wait for the new signal of keyboard input, if in the process preset time, for example in 10 minutes, there is not new input signal, microprocessor just jumps to step 100, and this step disconnects power circuit and stops power supply, and at this moment pressing button 5 just can restart the power supply power supply again.
In step 66, if result relatively is inappropriate, then microprocessor is again with M among input signal and the EEPROM23
2The emergency cryptosystem of cellular zone compares (step 68).If comparative result is inappropriate, then microprocessor just encourages LED1 to demonstrate error code symbol " E " (step 30), and then, microprocessor is read the output (step 82) of a counter.This counter is by setting certain counting and providing by following this counting of the increase that is about to speak of in EEPROM22.When lockset is in opening, this counter is set at zero at first, step 78 is such as previously described, once wrong number of every input and lock cipher and emergency cryptosystem be not more when " coupling " when unblanking, counter just adds 1(step 88), if the output number of counter was less than 3 o'clock, microprocessor jumps to the input that step 99 is waited for new signal.Unblank when 3 error codes of continuous input, the output number of counter will meet or exceed 3 times, and then microprocessor just encourages the buzzer alarm (step 84) of sounding a buzzer.Subsequent, microprocessor jumps to step 86, and in step 86, microprocessor is in interrupt status within the predetermined time, and microprocessor interrupts accepting the new signal of keyboard input in this preset time, and for example establishing preset time is 15 minutes.Behind this section preset time, microprocessor jumps to step 99 again and enters wait state.
If the input error code unblanks to make the output number of counter to reach at 2 o'clock continuously, error code of every input is unblanked then, microprocessor all carries out step 60,62,64,68,80,84,86 and 99 in order, each operation the buzzing alarm all can occur and the lockset interrupt signal is imported 15 minutes, up to opening lockset, make till the counter reset to 0 with correct password.As long as this arrangement makes user's maloperation be no more than 2 times, lockset just can not send false alarm, and the user can the correct password of very fast usefulness open lockset, simultaneously, can prevent that again the criminal from carrying out continuous examination sign indicating number and unblanking.
If relatively more frequent or other reason owing to the lock cipher conversion code, the user has been forgotten compile the lock cipher of depositing and can not open lockset the time, the user can be by the input emergency cryptosystem, by impelling microprocessor in order from step 60, to step 99, lockset is opened through step 62,64,66,68,70,72,74,76,78.
After lockset 01 was unlocked, the user can compile lockset and deposit new password.Suppose that the operator imports one group of number by the figure key of keyboard 10, then by function key 4, then microprocessor 24 is from step 60, proceed to step 64 through step 62, because lockset turn-on flag 1 resets, as top step 76 was described, then microprocessor jumped to 90, in step 90, microprocessor is read the signal of keyboard input.If imported digital signal, then microprocessor compares (step 91) with the digital signal of input with the emergency cryptosystem that is stored among the EEPROM23.If result relatively is " equating ", then microprocessor is provided with mark 2(step 102).Then, microprocessor excitation display screen LED1 displaying symbol " U " (step 104).As following pointed, display screen displaying symbol " U " shows that mark 2 has set, and the user can compile lockset 01 and deposit new emergency cryptosystem in.Subsequent, microprocessor jumps to step 99, and is not having operating electrical machines 31 to make the new input signal of wait under the lockset locking situation.If but in step 91, result relatively is inappropriate, then microprocessor just jumps to step 92 from step 91.In step 92, microprocessor determines whether mark 2 has setting, and as described in the preceding step 102, if mark 2 has set, then microprocessor deposits the M of EEPROM23 in regard to the number that makes input
2Unit (step 106).At this moment, deposit M in
2The new password of cellular zone has just been changed the emergency cryptosystem of lockset, and then, microprocessor is removed mark 2 or made this mark reset (step 108).Subsequent, the microprocessor excitation display device repeats to show digital N time (step 94) of input.Make the operator can confirm and remember the emergency cryptosystem that enrolls repeatedly.After this, microprocessor exciting electric 31(step 95).And the red LED7(step 96 of connection).Make 180 ° of drives of gear 38 rotations pins 40 move to the B point from the A point when motor 31 rotates, when making the lockset locking, microprocessor just makes motor 31 stop (step 97).Subsequent, microprocessor is provided with mark 1(step 98 in EEPROM22).Then, microprocessor by step 99 proceed to step 100 make the power supply stop.
After supposition lockset 01 is opened now, the number of user's input does not conform to emergency cryptosystem, and mark 2 is not provided with, press 4 microprocessors of function key from step 60, proceed to step 93 through step 62,64,90,91,92, in step 93, microprocessor makes the digital M that deposits EEPROM23 in of input
1Cellular zone, at this moment M
1In former lock cipher just newly deposited in M
1Password change.Subsequent, microprocessor goes on through step 94,95,96,97,98,99, finishes up to step 100.
Any that should illustrate, in step 94, when display screen repeated to show the input number, the time interval that repeats to show between digital group and the digital group will obviously be longer than the time interval that shows by turn between the number, and the person can accurately remember lock cipher or the emergency cryptosystem that volume is deposited to make the coding.
After if lockset 01 is unlocked, the operator does not import digital signal, just 4 microprocessors of functional key 60,62,64,90,95,96,97,98,99 carry out set by step, make lockset enter locking states, finish up to step 100, this operation can not change lock cipher and the emergency cryptosystem among the EEPROM23.
Should be noted that, after microprocessor is provided with mark 2 through step 102, if the operator does not import number, it is pressing function key 4, then microprocessor is from step 60, proceeds to step 100 through step 62,64,90,95,96,97,98,99, and microprocessor is under the situation of not changing lock cipher among the EEPROM23 and emergency cryptosystem, make the lockset locking and stop power supply, then lock cipher among the EEPROM23 and emergency cryptosystem all are not replaced or remove.
Above described disclosing implement microcomputerized puzzle lock of the present invention, yet, can carry out some modifications and conversion to it not departing under the situation of the present invention.Such as, can be with the gear drive between gear 32 and the gear 33, and the gear drive between gear 37 and the gear 38 becomes the belt pulley transmission, is about to described gear 32 and 33 or 37 and 38 and makes belt pulley into.
Also have, can carry out such modification to Fig. 4: can cancellation step 104, make step 102 directly guide to step 94, through step 95,96,97,98 to step 99, in this case, when emergency cryptosystem is made amendment, after will importing emergency cryptosystem earlier coded lock being opened, import one group of new digital operation of changing the emergency cryptosystem of coded lock again, like this, though change the more preceding complexity of operational motion of emergency cryptosystem, owing to when coded lock is in opening, occurred importing under the digital identical situation with emergency cryptosystem, display unit special prompt can not occur, this has just improved the confidentiality of emergency cryptosystem, so the present invention disclosed by way of example, and illustrated embodiment does not provide constraints to the present invention.
