Close, then the secondary lock control module sends alarm command, the main lock control by bluetooth or WIFI wireless telecommunications to the main lock
The molding block control main lock voice guard sends acousto-optic and warned.
Typically register one's residence this blocking lock operation principle：
It is main to be locked in password, swipe the card or the mode such as fingerprint recognition is by rear, send unlocking signal motor driving lock core latch and open
Lock, main lock is then opened, when depression of handle opens external door, while main lock is by built Bluetooth module, is sent encrypted instruction and is passed through
Wireless signal sends secondary lock to, and pair lock receives decryption instructions after signal by built Bluetooth module, sends unlocking signal, and pair lock drives
Dynamic motor drive pair lock pin is unlocked, then secondary lock is also opened, and resident family's depression of handle is opened inside door and entered, and then shuts external door and interior
Door.
For linkage door operation principle：
Lead and be locked in password, swipe the card or fingerprint recognition mode is by rear, send unlocking signal motor driving lock core latch and unlock,
Main lock is then opened, and depression of handle is opened after external door enters and closed the door, and main be locked in detects master by main lock infrared signal detection module
Door is then automatic locking after shutting, if not closed more than setting time is to alarm, then main lock is sent and added by built Bluetooth module
Close instruction sends secondary lock to by Bluetooth signal, and pair lock receives decryption instructions after signal by built Bluetooth module, sends unlocking
The lock core latch of signal drive motor drive pair lock is unlocked, then secondary lock is also opened, and depression of handle is opened inside door and entered, and pair is locked in logical
Cross secondary lock infrared signal detect it is then automatic locking after inside door is shut, if not closed more than setting time alarm.Opposite direction base
Originally identical, the secondary handle locked on rear board of pressure is unlocked, and is gone out the interior closure of inside door behind the door and is locked, if not closed more than setting time be
Alarm, while signaling main lock by pair lock wireless communication module, the handle pressed on main lock rear board opens external door, goes out
Close external door master behind the door outside to lock, if not closed more than setting time alarm.If inside door is not locked, by main lock rear board
Unlocking handle can not open external door.
For Airshower chamber operation principle：
With it is similar for linkage door operation principle, the door-master of external door-entrances external door-outside the Pass is simply opened outside and is locked after lock,
The need for according to dedusting, time-delay relay is respectively mounted in main lock and secondary lock, time-delay relay is locked with main lock control module, pair
Control module is connected, main Lock Lee internal clocking function, and unlocking instruction is just sent out after the delay time of setting terminates and is opened to secondary lock
Inside door is opened, during delay dedusting, main lock and secondary lock are in lock-out state, and inside door or external door cannot be all opened from inside and outside.Instead
Direction need not then be delayed.Main lock control module and secondary lock control module use single-chip microcomputer.Bluetooth module and WiFi module
It can be obtained by buying.
It should also be appreciated by one skilled in the art that the various illustrative boxes described with reference to the embodiments herein, mould
Block, circuit and algorithm steps can be implemented as electronic hardware, computer software or its combination.In order to clearly demonstrate hardware and
Interchangeability between software, is carried out to various illustrative parts, frame, module, circuit and step around its function above
It is generally described.Hardware is implemented as this function and is also implemented as software, depending on specific application and to whole
The design constraint that system is applied.Those skilled in the art can be directed to each application-specific, be realized in the way of flexible
Described function, it is still, this to realize that decision-making should not be construed as the protection domain away from the disclosure.
