Memory, for storing user's facial image and corresponding encrypted message and user information.
Electronic lock provided by the invention, in use, all parts are carried out as follows cooperating.
In information collection and memory phase:
Touch display screen shows user's prompt information, which is information relevant to the acquisition of user's face, such as positive faceTo information such as camera or screens.Subsequent picture collector acquires active user's face direct picture, and the face is positiveImage is sent to controller, then is sent in video procession device by controller.
Video procession device forms the face figure of prescribed form after being handled the face direct picture receivedDecent, and memory is sent by above-mentioned image pattern.Multiple user's facial images are stored in the manner described above forms faceDatabase.And specific face image processing mode belongs to the prior art, repeats no more.
Controller issues password and acquires signal, control touch display screen shows user after face acquisition and storagePassword acquisition interface.
For touch display screen after receiving password acquisition signal, prompt user carries out password acquisition first, and then showsAge of user input interface, after user inputs actual age, above-mentioned age information is sent controller by touch display screen, controlDevice processed is judged for age information according to all age group, such as 6-12,13-50,51-100, and 6-12 years old is determined asChild is determined as ordinary people for 13-50 years old, is determined as the elderly within 51-100 years old.Then, controller is defeated according to judging result progress passwordEnter the determination at interface, if it is judged that for children perhaps old man due to children and old man's memory it is limited or be easy to forgetToo long of numerical ciphers, so controller controls few Password Input circle of touch display screen figure place showing according to above-mentioned judging resultFace, such as 3 or 4 bit digital interface for password input.After user carries out numerical ciphers input according to prompt, touch display screen will be defeatedThe numerical ciphers information entered is sent to controller, is sent in memory by controller, by encrypted message and age of user informationMemory is stored in the binding of user's facial image.If it is judged that being ordinary people, since the memory of ordinary people does not have generallyIt is problematic, so controller controls the interface for password input that touch display screen shows normal digit, such as 6 according to above-mentioned judging resultThe position password etc. that perhaps 8-10 bit digital password or number are combined with letter.Then, user carries out numerical ciphers according to promptAfter input, the encrypted message that the numerical ciphers of input or number and letter combine is sent controller by touch display screen, byController is sent in memory, and encrypted message and age of user information and the binding of user's facial image are stored in memory.
In the manner described above, controller is believed by kinsfolk or using everyone face in the user of the electronic lockBreath and encrypted message store by touch display screen typing and form user's face database into memory.
Face and password identification authentication phase when unlocking:
The facial image of user that image acquisition device acquisition currently needs to unlock, by controller be sent to image procossing withIdentifier.
After video procession device receives facial image, facial image is pre-processed, the pretreatment is according to depositingPicture format in reservoir in face database is handled.Then, video procession device will treated facial imageIt is compared with the facial image stored in memory, and control is sent to according to comparing result and corresponding user informationDevice.After video procession device compares successfully, by the corresponding user information of facial image in memory, (such as the age believesBreath) and the corresponding encrypted message of the user be sent to controller.When the comparison of video procession device is unsuccessful, by the resultNotification controller.
If controller receives the user information and encrypted message of video procession device transmission, judge that user believesAge corresponding user type in breath is judged, controller judges active user for children according to age bracket above-mentionedOr when the elderly, the few interface for password input of control touch display screen figure place showing after subsequent user inputs password, is touched aobviousThe encrypted message of input is sent controller by display screen.Controller sends the password of input with video procession device closeCode information compares, if correctly, controller controls door interlock switch, opens electronic lock, if incorrect, controller noticeTouch display screen shows user's prompt information of password mistake, and controls touch display screen and continue to show interface for password input.
Likewise, if control touch display screen shows the normal digit in position when controller judges active user for ordinary peopleInterface for password input, such as number and alphabetical input interface, after subsequent user inputs password, touch display screen is by the password of inputInformation is sent to controller.Controller compares the encrypted message that the password of input is sent with video procession device,If correct, controller controls door interlock switch, opens electronic lock, if incorrect, controller notice touch display screen is shownUser's prompt information of password mistake, and control touch display screen and continue to show interface for password input.
In addition, control touches when the comparison that controller receives the transmission of video procession device unsuccessful noticeThe unsuccessful prompt information of display screen display unlocking, and simultaneously send active user's facial image that image acquisition device acquires toInformation transceiver, subsequent information transceiver are sent in remote user equipment by network.
Above-mentioned remote user equipment, such as smart phone, after receiving the user's facial image for currently needing to unlock, user sentencesThe facial image that breaks belongs to acquaintance or household, sends unlocking instruction by remote user equipment, controller receives unlocking and refers toWhen enabling, control door interlock switch is checked card, and completes user's remote unlocking, avoiding household children, perhaps old man etc. forgets Password or do not haveThere is typing information and can not enter.If user judges that the facial image belongs to stranger, sent not by remote user equipmentUnlocking instruction, the control after controller receives not unlocking instruction, without door interlock switch.
