Photo resistance, at the fastening of door-plate and doorframe, for sending door signal to microcontroller when door fastens；
Microcontroller, for controlling electric lockset to lock according to door signal, it is additionally operable to be controlled according to fingerprint recognition signal
Electric lockset unlocks；
The microcontroller is built-in with time block, the timing that the time block is used for after electric lockset unblock
Inside lock again.
The working principle and beneficial effect of this programme is：When user opens gate inhibition and entered in room, first referred to by first
Line identifier takes the fingerprint of people and forms fingerprint recognition signal, when microcontroller judges that fingerprint recognition signal is correct, micro-control
Device control electric lockset unblock processed, allows user to push into room, while electric lockset unlocks, the timing in microcontroller
Module is timed, and is not pushed also into room when timing terminates user, and microprocessor control electric lockset is locked pass
Door-plate is closed, avoids user from being introduced into room after electric lockset is unlocked and forget to close the door.
After user enters room, photo resistance is stopped by doorframe, raises the resistance of photo resistance, photosensitive electricity
Resistance passes to the resistance rise signal of microcontroller as door signal, allows electric lockset to be closed automatically after user enters room
Close, avoid user from forgetting to close the door after entering room.
The design is automatic locking again into room by regularly being locked again after unblock, and after unblock, avoids using
Person forgets to lock shutdown and make other people entrance.
Explanation：Inner side refers to side of the handle towards door-plate.
Further, in addition to loudspeaker, for being sent in electric lockset lock and unlock according to the signal of microcontroller
Prompt tone.
When electric lockset lock and unlock, user is prompted by sound, is confirmed without using person by pushing
Whether door is turned off, and using more convenient, and user can also be reminded to be passed in and out after enabling within the defined time, avoid using
Person does not pass in and out room and forgets to close the door after opening the door.
Further, in addition to Smoke Sensor, positioned at panel towards on side in room, during for fire to occur indoors
Sense smokescope and send fire signal to microcontroller, the microcontroller is additionally operable to control electronic lock according to fire signal
Tool unblock.
When fire occurring indoors, by Smoke Sensor automatic sensing smokescope, and in smokescope more than a certain amount of
When, control electric lockset unblock, which allows, opens, and avoids people in case of emergency flurried and can not open door escape.
Further, emergency tank is further opened with the panel, the second Fingerprint Identification Unit is installed in the emergency tank, it is described
Second Fingerprint Identification Unit is used to send enabling signal to microcontroller in the first Fingerprint Identification Unit failure.
When the first Fingerprint Identification Unit breaks down and can not open the door or at closing time, is temporarily opened by the second Fingerprint Identification Unit
Door and close the door, without changing locksmith to handle when urgent, using more convenient, and without lead in the first Fingerprint Identification Unit failure
Destruction gate inhibition is crossed to open the door, adds the service life of gate inhibition.
Further, the emergency tank is located at the lower section of handle.
When the first Fingerprint Identification Unit does not break down, opened the door by handle and door-closing operation will not be touched in emergency tank
The second Fingerprint Identification Unit, avoid touching the second Fingerprint Identification Unit by mistake and influenceing the use of the first Fingerprint Identification Unit.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment；
Fig. 2 is the theory diagram of the utility model embodiment control section.
Embodiment
The utility model is described in further detail below by embodiment.
Reference in Figure of description includes：Panel 1, handle 2, key hole 3, emergency tank 4, the second fingerprint recognition
Device 5.
Intelligent access control system, as depicted in figs. 1 and 2, including the panel 1 on door-plate, door-plate are arranged on doorframe,
Doorframe is arranged on the door opening of wall, and handle 2 is welded on panel 1, is provided for not open by fingerprint on panel 1
The key hole 3 used during door, and allow key hole 3 to be located at the top of handle 2, the first fingerprint recognition is fixedly mounted in handle 2
Device, and the first Fingerprint Identification Unit is arranged on handle 2 towards on indoor side, allow user to be taken while handle 2 are held
Fingerprint, using more convenient.
An emergency tank 4 is also opened up on panel 1, the second Fingerprint Identification Unit 5 is installed, and emergency tank 4 is opened in emergency tank 4
