Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, an embodiment of the present application provides a multi-fingerprint head access control system, which includes an access controller 101, an electric control door lock 102, and at least two fingerprint heads 103, where the at least two fingerprint heads 103 are sequentially disposed on a door handle from top to bottom;
the access controller 101 is respectively connected with the electric control door lock 102 and each fingerprint head 103; each fingerprint head 103 can be sequentially arranged on the side surface of the door handle facing the door body from top to bottom; the door access controller 101 may be disposed inside a door handle.
A fingerprint head 103 for collecting a fingerprint image input by a user;
the access controller 101 is configured to, when any one of the at least two fingerprint heads 103 collects a fingerprint image, compare the fingerprint image with a fingerprint information set corresponding to the fingerprint head 103, and when the fingerprint image matches any one of the fingerprint information sets, control the electronic control door lock 102 to be opened;
an electric control door lock 102 for performing an opening or locking operation under the control of the entrance guard controller 101.
The fingerprint head 103 may be an optical fingerprint head 103 or a semiconductor fingerprint head 103.
The system comprises a plurality of fingerprint heads 103, when any fingerprint head 103 collects a fingerprint image, the access controller 101 only adopts a fingerprint information set corresponding to the fingerprint head 103 to verify the collected fingerprint image, so that the data volume required to be compared is reduced, the verification time is shortened, and the access controller is beneficial to improving the work efficiency of the access controller; meanwhile, the fingerprint heads 103 are arranged on the door handle, so that a user can finish fingerprint verification when holding the door handle to open the door, the door opening time can be saved, and the door opening system is more convenient to use.
In particular, door handles generally include a handle base and a handle grip.
In one embodiment, at least two fingerprint heads 103 can be sequentially arranged on the inner side surface of the door handle facing the door body from top to bottom, and as each fingerprint head 103 is arranged on the inner side surface of the door handle facing the door body, the outside cannot be seen, so that the attractive appearance of the door handle is ensured, dust accumulation of the fingerprint heads 103 can be prevented, and the service life of the fingerprint heads 103 is prolonged.
In order to further improve the verification efficiency, in the above embodiment, the fingerprint information in each fingerprint information set may be prioritized according to fingerprint types, where the fingerprint types refer to fingerprints of different fingers such as thumb, index finger, middle finger, etc. For example, when the plurality of fingerprint heads 103 are provided on the inner side surface of the door handle, in consideration of the usual gesture when the door handle is held by a human hand, fingerprint information corresponding to the index finger and the middle finger may be set to a first priority, fingerprint information of other fingers may be set to a second priority, the collected fingerprint image and the fingerprint information of the first priority may be verified first, if the verification is passed, the electronic control door lock 102 is controlled to be opened, and if the verification is not passed, the fingerprint image and the fingerprint information of the second priority may be compared to determine whether to open the door.
In another embodiment, at least two fingerprint heads 103 are sequentially arranged on the outer side surface of the door handle opposite to the door body from top to bottom. Since each fingerprint head 103 is sequentially arranged on the outer side surface of the door handle back to the door body from top to bottom, the positions of each fingerprint head 103 are clear at a glance, and the user can conveniently and directly input fingerprints.
In the above embodiment, the fingerprint information corresponding to the thumb may be set to the first priority, and the fingerprint information of the other fingers may be set to the second priority; the configuration principle of the fingerprint priority is the same as that of the previous embodiment, and is considered to be a common holding gesture, and will not be described herein.
In the prior art, after the door control system is installed, the position of the single fingerprint head 103 is usually fixed. However, for families with the same residence of several generations, the child is shorter, the fingerprint head 103 is often difficult to reach, and meanwhile, due to the possible difference of heights of men and women, the height difference exists between the positions where hands are naturally placed when the two doors are opened, so that the user often needs to specially lower or raise arms when verifying the fingerprint, and the user experience is affected.
In some embodiments, referring to fig. 2, when the length of the door handle is greater than or equal to the first threshold, two or three fingerprint heads 103 are provided on the door handle, and the separation distance between the fingerprint heads 103 is greater than the distance threshold.
The first threshold and the distance threshold can be set according to actual needs, for example, the first threshold can be a value between 25 cm and 45 cm, and the distance threshold can be a value between 5 cm and 15 cm.
When the door handle is a long door handle, the length of the door handle can exceed or be equal to a first threshold value, 2-3 fingerprint heads 103 which are sequentially arranged from top to bottom can be arranged on the door handle, and certain intervals are kept between the fingerprint heads 103, so that the fingerprint heads 103 at different positions can adapt to the heights of different people, more natural interaction effects are achieved, and the use experience of users is improved.
For example: the family has old people, couple and children, the husband is the highest, the wife is the middle, the old people and children are shorter, and the door handle is provided with a first fingerprint head, a second fingerprint head and a third fingerprint head from top to bottom; then the first fingerprint head corresponds to the fingerprint information set which only stores the fingerprint information of the husband, the second fingerprint head corresponds to the fingerprint information set which only stores the fingerprint information of the wife, and the third fingerprint head corresponds to the fingerprint information set which only stores the fingerprint information of the aged and the children.
In one implementation manner of the foregoing embodiment, the access controller 101 is configured to mark, in advance, a fingerprint information set corresponding to each fingerprint header 103 as a primary fingerprint information set of the fingerprint header 103, and mark, as a secondary fingerprint information set of the fingerprint header 103, fingerprint information sets corresponding to other fingerprint headers 103 except the fingerprint header 103;
The access controller 101 is further configured to compare the fingerprint image with a first-level fingerprint information set of any fingerprint head 103 when the fingerprint head 103 of the fingerprint heads 103 collects the fingerprint image; if the fingerprint image is matched with any fingerprint information in the primary fingerprint information set, the electronic control door lock 102 is controlled to be opened; if the fingerprint image is not matched with all the fingerprint information in the primary fingerprint information set, the fingerprint image is compared with the secondary fingerprint information set of the fingerprint head 103, and when the fingerprint image is matched with any one of the secondary fingerprint information set, the electric control door lock 102 is controlled to be opened.
Specifically, if the fingerprint image is not matched with all the fingerprint information in the secondary fingerprint information set, the access controller 101 does not control the electric control door lock 102 to be opened, the access is still locked, and the access safety is ensured.
In a specific implementation process, the condition that a user inputs a fingerprint at the fingerprint head 103 which is not corresponding to the user may occur, so the embodiment adopts a two-stage verification mode, the collected fingerprint and the first-stage fingerprint information set are verified first, and the second-stage fingerprint information set is verified only under the condition that the primary verification is not passed, so that on one hand, the timeliness of fingerprint verification can be ensured by only performing the first-time verification under the condition that the user inputs the fingerprint at the corresponding fingerprint head 103, and on the other hand, the door lock can be opened by performing the second-time verification according to the condition that the user uses the non-corresponding fingerprint head 103, thereby avoiding the condition that the user is out of door due to the error of the used fingerprint head 103, and avoiding the user from moving to other fingerprint heads 103 for verification, thereby being beneficial to improving the user experience.
In practice, since a user typically uses an upper finger print to perform fingerprint verification while holding the door handle, the existing single fingerprint head 103 is typically disposed at a position above the door handle. However, there are two cases of door handles when installed: the door body is arranged on the left side for opening the door and the door body is arranged on the right side for opening the door. For a short door handle with only one fingerprint head 103, when the door handle is installed at a left door or a right door, the position of the door handle can be overturned, so that the user finger is difficult to align with the acquisition area of the fingerprint head 103, the use experience is affected, and the door handle has poor replaceability.
In some embodiments, referring to fig. 3, when the length of the door handle is less than or equal to the second threshold, two fingerprint heads 103 are provided on the door handle, and the two fingerprint heads 103 are symmetrically arranged with the horizontal center line of the door handle as an axis.
The second threshold value can be a value between 10 cm and 25 cm.
Specifically, when the door handle is a short door handle, the length of the door handle is smaller than or equal to the second threshold value, at this time, 2 fingerprint heads 103 can be symmetrically arranged on the door handle, no matter the short door handle is arranged on a left door or a right door, a user fingerprint (usually a fingerprint of an index finger or a middle finger) can conveniently contact with a collection area of the fingerprint heads 103, and the door handle is not influenced by an installation position and has better replaceability.
In one implementation of the foregoing embodiment, the fingerprint information sets corresponding to the two fingerprint heads 103 are the same fingerprint information set.
The door control system in this embodiment adopts the short door handle with two fingerprint heads 103 symmetrically arranged up and down as a fingerprint collection structure, and mainly plays a role in improving the applicability of the door handle, so that the same fingerprint information set can be adopted during verification.
In specific implementation, the door control can be opened by touching any fingerprint head 103, and the door control can be opened by touching another fingerprint head 103 when one fingerprint head 103 fails.
In the above embodiments, the first threshold is generally configured to be greater than the second threshold.
In some embodiments, the access controller 101 is further configured to send early warning information to a preset terminal when the fingerprint image acquired by any one fingerprint head 103 of the at least two fingerprint heads 103 is a duress fingerprint.
The duress fingerprint is a certain fingerprint preset by a user, and is usually a less-used fingerprint, such as a ring finger or a little finger fingerprint; the preset terminal can be a property safety terminal, a security company terminal, a specified user mobile terminal and the like; the early warning information is used for carrying out preliminary safety early warning prompt on a preset terminal.
Specifically, when the access controller 101 detects that the fingerprint image is a duress fingerprint, the electronic control door lock 102 can be controlled to be opened, so that a duress person is prevented from making a behavior of endangering the personal safety of the user, and the user safety is ensured.
In one embodiment, the user may preset a first duress fingerprint and a second duress fingerprint, i.e., the duress fingerprint may include the first duress fingerprint and the second duress fingerprint; when the access controller 101 detects that the fingerprint image is a first duress fingerprint, the electronic control door lock 102 is controlled to be opened, and early warning information is generated and sent to a preset terminal; when the access controller 101 detects that the fingerprint image is the second duress fingerprint, the early warning information is sent as well, but the electric control door lock 102 is not opened. Under duress, the user can select to input the first duress fingerprint or the second duress fingerprint by himself.
Further, the access controller 101 may be further configured to determine that a duress event occurs when the fingerprint image acquired for the first time is a second duress fingerprint and the fingerprint image acquired for the second time is the first duress fingerprint, and send alarm information to the preset terminal. The alarm information has higher intensity than the early warning information, and can be sent to the terminal for alarm sound reminding. At this time, the system can more accurately judge whether a duress event occurs through two different duress fingerprints, so that timely alarm is realized.
In one implementation of the foregoing embodiment, the system further includes an outdoor ambient sound collection module and an indoor ambient sound collection module;
the access controller 101 is further configured to, when a fingerprint image acquired by any one fingerprint head 103 of the at least two fingerprint heads 103 is a duress fingerprint and the electronic control door lock 102 is not opened, open the outdoor environmental sound acquisition module to acquire outdoor environmental audio; converting outdoor environment audio into first text information; when the first text information is detected to contain dangerous words, alarm information is sent to a preset terminal;
the access controller 101 is further configured to, when a fingerprint image acquired by any one fingerprint head 103 of the at least two fingerprint heads 103 is a duress fingerprint, and the electronic control door lock 102 is opened, open the indoor environment sound acquisition module to acquire indoor environment audio; converting the indoor environment audio into second text information; and when the second text information is detected to contain dangerous words, sending alarm information to a preset terminal.
The outdoor environmental sound collecting module can be a pickup arranged in the door handle; the indoor environmental sound collection module can be recording equipment and the like arranged indoors; the dangerous words may be preset by the user.
The system in this embodiment can acquire the outdoor environment audio and the indoor environment audio before and after the electric control door lock 102 is opened through the outdoor environment sound acquisition module and the indoor environment sound acquisition module respectively, then convert the audio into characters, judge whether a stress event occurs by detecting whether dangerous words are contained in the characters, improve the alarm accuracy rate and reduce the false alarm rate.
In some embodiments, the access controller 101 is connected to an indoor smart home system;
the access controller 101 is further configured to determine user identification information corresponding to the fingerprint image when the fingerprint image matches any one of the fingerprint information sets; acquiring home environment configuration information corresponding to user identification information; and controlling the indoor intelligent home system to adjust the indoor home scene according to the home environment configuration information.
The indoor intelligent home system can be an intelligent control system comprising an air conditioner, light, sound and the like; the home environment configuration information may include configuration information such as indoor temperature, light intensity, fragrance, music, etc.
Specifically, the access controller 101 may adjust the indoor home scene to a scene state preferred by the user according to corresponding configuration information preset by the user.
The system in this embodiment connects the indoor intelligent home system through the access controller 101, and after the user identity is identified through the fingerprint, the indoor home scene is adjusted according to the home environment configuration information corresponding to the user, so that the access system and the indoor intelligent home system are combined, and a better home experience effect is achieved.
In some embodiments, the access controller 101 is further configured to determine user identification information corresponding to the fingerprint image when the fingerprint image matches any one of the fingerprint information sets; acquiring a message event corresponding to the user identification information; and pushing the message according to the message event.
The message event comprises a message to be pushed and a target user, wherein the target user can be a user who passes through the gate currently or other users who are not on site; specifically, the access controller 101 pushes a preset message to be pushed to the target user. For example, when the access control system detects that a child goes home, a complementary shift receiving reminding message can be pushed to an external user; or when the family member enters the home, pushing a dish buying reminding message or a family member home prompting message to an external user.
After the system in this embodiment can identify the user identity through the fingerprint, the system performs message pushing according to the message event corresponding to the user identity, so as to implement various message reminding functions.
In some embodiments, for the case that fingerprint identification fails due to insensitivity of fingerprint head identification or deviation of identification of the access controller during implementation, the access controller may record fingerprint information of identification failure first, for example, in a first preset period after the fingerprint of identification failure is stored, the user inputs a matched fingerprint, if the access is successfully released, the fingerprint information of identification failure is marked as pending fingerprint information, and the number of occurrences of the same pending fingerprint information is recorded. The first preset duration is shorter, and can be between 5 seconds and 60 seconds, and the undetermined fingerprint information recorded in the first preset duration can be the user's own fingerprint.
The access controller can monitor and update the occurrence times of each piece of to-be-determined fingerprint information in real time, and can count the occurrence times of each piece of to-be-determined fingerprint information recorded in a preset time period every other time period; when the occurrence number of certain undetermined fingerprint information exceeds the preset number, the undetermined fingerprint information is a certain fingerprint which is frequently used without inputting a fingerprint information set by a user or a fingerprint which is input by the user but not normally identified by the access controller. At this time, the fingerprint information to be determined can be compared with each item of fingerprint information stored in the current fingerprint information set, and whether fingerprint information with similarity greater than a preset percentage with the fingerprint information to be determined exists or not is searched; if the fingerprint information with the maximum similarity with the undetermined fingerprint information is selected as target fingerprint information, the undetermined fingerprint information is used for updating the target fingerprint information, the updating mode can be that the undetermined fingerprint information is used for replacing original target fingerprint information, or the undetermined fingerprint information is fused with the original target fingerprint information to obtain new fingerprint information, so that the fingerprint identification passing rate of a subsequent access control system is improved; if the fingerprint exists, a fingerprint confirmation prompt message can be sent to the user to remind the user to confirm the pending fingerprint or re-enter fingerprint information.
In addition, when the occurrence number of certain undetermined fingerprint information exceeds the preset number, the access controller can also not compare the undetermined fingerprint information with each item of fingerprint information stored in the current fingerprint information set, but directly send a fingerprint confirmation prompt message to the user to prompt the client to update or confirm the fingerprint information in time so as to reduce the probability that the access control system cannot recognize.
Based on the above embodiment, after the access controller records the fingerprint information of the identification failure, if the user fails to detect the matched fingerprint to release the access within the first preset duration, the fingerprint information of the identification failure is marked as risk fingerprint information, and the number of occurrences of the same risk fingerprint information is recorded. When detecting that the occurrence frequency of certain risk fingerprint information reaches a risk frequency threshold, the access controller can send a risk early warning message to a user terminal or a property safety platform so as to remind a user or a property management person of risk; in specific implementation, the access controller can be connected with a monitoring camera nearby the outside of the door, the monitoring camera is in a closed state at ordinary times, and only when the number of times of occurrence of certain risk fingerprint information reaches a risk number threshold value, the access controller is controlled to open and shoot an area outside the door so as to acquire a current image containing images of risk personnel and generate a risk early warning message containing the current image.
In some embodiments, the system further comprises a backup verification module;
the standby verification module comprises one or more of a password verification module, a face verification module and an iris verification module.
The system provided in this embodiment may further be equipped with one or more backup verification modules, so that when the fingerprint head 103 fails, verification may be continued to ensure stability and security of the system.
It should be noted that the standby verification modules used in the above embodiments are all mature technologies in the prior art, and all matters not described in detail in this specification belong to the prior art known to those skilled in the art.
