Road works, the conducting of main control chip driving power holding circuit；After key is extracted, main control chip detection key is extracted, and is then controlled
Power supply holding circuit disconnects, and system 0 powers off, and returns to original state.P-GND output level is controlled by main control chip, works as master control
Q7, Q8, Q9 are turned on when chip exports high level so that PGND networks are connected with GND, circuit is formed closed-loop path.Conversely, work as
When main control chip exports low level, Q5, Q6, Q7 cut-off, PGND networks disconnect with GND, and whole circuit can not form loop.
The course of work of the present invention is as follows：As shown in Figures 12 and 13, using the method for " double verification "：First key side with
First second singlechip of cylinder side first verifies whether the equipment with model for same producer；Then the ID chips of key side are verified again
Whether the ID number of middle storage is preserved by the second singlechip of cylinder side.It is not shape with broadcast that the ID of key side, which can so be allowed,
Formula, strengthen the stability and security of communication.Verify and sent out by the first single-chip microcomputer of key side by infrared transceiver module first
Send the square-wave signal of specific frequency.One is postbacked if the second singlechip of cylinder side receives by infrared transceiver module the signal
The square-wave signal of different frequency；Waiting the first single-chip microcomputer to receive return signal, then checking is completed first.Secondary checking：Key side
First single-chip microcomputer sends key ID number by infrared transceiver module, and the second singlechip of cylinder side receives posteriority by infrared module
Card whether be storage inside effective ID, be, motor clamping dead bolt buckle allow key rotate enabling on the contrary driving honeybee
The device that rings is alarmed.
When key inserts lock core, the microswitch in triggering lock, machine is established by cable on the second singlechip in lock, utilizes first
The key id information of first single-chip microcomputer memory storage is sent the second infrared transceiver module by infrared transceiver module.Then second singlechip
The ID data that second infrared transceiver module receives are compared with the legal id information stored, if the key is legal key
Spoon, second singlechip meeting motor, makes dead bolt buckle clamping, if now the pellet of the key and the lock gall locked match, uses
Family can rotates key and opened the door.If the key is illegal key, single-chip microcomputer will not motor clamping dead bolt buckle, but
Driving buzzer sends alarm.Second singlechip meeting motor reversion, departs from dead bolt buckle, now after key is extracted
Having cracked mechanical lock using technological means can not also unlock.
On the basis of the above, the concept of " management key " is introduced." management key " physically with normal key complete one
Cause, simply its id information is written into when dispatching from the factory in the main control chip in lock, is matched with lock core；User can be by managing key
Spoon is come the unlocking authority that adds or delete normal key.Prevent for the sake of security " management key " lose, " management key " no
Have the function that to open door.
" management key " specific management process is as follows：
Key insertion lock core is managed, band lock core is identified as extracting after managing key insertion, is subsequently inserted into any common key
Spoon, their id information will be preserved by the main control chip in lock core so these normal keys, which are just provided with, opens this lock core
Authority；The authority of the normal key of all existing unlocking authorities can be then deleted when continuous 2 times plug management keys, is then inserted again
Enter it is any normal key then these normal keys just be provided with open this lock core authority.
