Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
As shown in Figs 1-4, the utility model provides a kind of entrance guard device based on a variety of living things feature recognitions, gate inhibition dress
It sets including gate inhibition's module, alarm module and CPU module, and that verifies opening door lock device mainly has face characteristic to test
Card, fingerprint authentication, vena metacarpea verifying and iris verification mode；
The operation of whole system be unable to do without power supply unit, main to be equipped with main power source 219 and backup power source 220, backup power source
It is to power off suddenly in order to prevent, easily causes information loss or equipment fault phenomenon.
The sequentially connected access control chip 222 of access control system and door-control lock 221.There is lockset driving interface on door-control lock
223, central processing unit is connected on the access control chip, receives the order of the module.CPU module connectivity verification,
Acquisition, storage, alarm and visitor's Registration Module, receive and send back the order of modules.The door-control lock of access control system is root
According to access control chip controls, and the chip receives the unlocking or shutdown command issued from central processing unit.If unlocking
The lockset driving interface of door-control lock is then opened in order, opens locking bolt 224, door is opened, on the contrary if shutdown command.Centre
Manage device unlocking or shutdown command, according to other modules effect as a result, generally visitor's Registration Module generate signal and
The signal that information authentication module generates.
Information Authentication is the pith of the access control equipment of kind of biological characteristic identification function, includes a variety of verification modes.Have
Iris 205, face 204, vena metacarpea 203 and 202 mode of fingerprint are selected for user.By taking face verification as an example, user selects face
The mode of verifying, as long as station is directed at camera before acquisition camera 206, by positive face, so that it may obtain about user face
Information.The information afferent message comparison module 207, central processing unit will obtain the knot of the information comparison in information authentication module
Fruit, at the same liquid crystal display 201 also can feedback validation result.Further according to this as a result, feeding back to gate inhibition's module.If repeatedly malice
Input, central processing unit issue alarm command to alarm module, and alarm for opening 225 and buzzer 226 gives a warning is reminded
User someone's malice is swarmed into.
Information storage, is the pith of the access control equipment of kind of biological characteristic identification function, is broadly divided into user information and deposits
Store up module 217 and visitor information memory module 218.By taking user stores as an example, when user selects data input, central processing can be given
Device transmits typing signal.According to the signal of transmission, central processing unit opening imformation acquires function.User inputs oneself in systems
Identity information, carry out real name registration, then the information is passed in subscriber information storing module by the order of central processing unit,
Information storage module carries database, is used to store all information of user.Information storage module is mainly in information comparison and letter
It is used when breath acquisition, information comparison module and information store shared database, and the selection of function is then given by central processing unit
Order out determines.
Information collection is the pith of the access control equipment of kind of biological characteristic identification function, and entire access control system
It is crucial.User first carries out real name registration 208, and then when being acquired, central processing unit can be according to the record of user's selection
Enter mode to open
Acquisition camera 206 or fingerprint capturer 213.If user selects iris capturing 212, user needs will be simple eye
It is directed at camera 216, obtains iris information；If user selects vena metacarpea acquisition 210, user needs palm being directed at camera
214, obtain vena metacarpea information；If user selects face acquisition 211, user needs positive face being directed at camera 215, obtains people
Face information.If desired fingerprint collecting 209, then need to be on fingerprint screen, and user can record fingerprint.The information that will be obtained, in
Central processor sends store command, these information are all stored to information storage module.The database of memory module is exactly to store
The various information that user's acquisition comes.
Central processing unit is the key that the entire access control system of control, can control acquisition, verifying, storage, door-control lock are opened
It closes.In this access control system, it is also contemplated that remove typing user information, stranger register the case where.So access control system
There are one visitor registration content, such as stranger want enter when, guest mode, central processing unit meeting are selected on liquid crystal display
Visitor's Registration Module is opened, tourist needs to carry out visitor's data registration 227 and visitor information acquisition 228.This module, mainly
The case where in order to record when stranger enters.
Embodiment:
