Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present 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 electrically controlled 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 entrance guard controller 101 is respectively connected with the electric control door lock 102 and the fingerprint heads 103; each fingerprint head 103 can be arranged on the side surface of the door handle facing the door body from top to bottom in sequence; the access controller 101 may be located inside the door handle.
A fingerprint head 103 for collecting a fingerprint image input by a user;
the entrance guard controller 101 is used for comparing the fingerprint image with a fingerprint information set corresponding to the fingerprint head 103 when any fingerprint head 103 of the at least two fingerprint heads 103 collects the fingerprint image, and controlling the electric control door lock 102 to be opened when the fingerprint image is matched with any fingerprint information in the fingerprint information set;
and an electrically controlled door lock 102 for performing an opening or locking operation under the control of the access 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 the fingerprint information set corresponding to the fingerprint head 103 to verify the collected fingerprint image, so that the data volume needing to be compared is reduced, the verification time is shortened, and the access control working efficiency is improved; meanwhile, the fingerprint heads 103 are arranged on the door handle by the access control system, so that fingerprint verification can be completed when a user holds the door handle to open the door, the door opening time can be saved, and the access control system is more convenient to use.
In particular, the door pull generally includes a door pull base and a door pull handle.
In an embodiment, at least two fingerprint heads 103 can be arranged on the inner side surface of the door handle facing the door body from top to bottom in sequence, and each fingerprint head 103 is arranged on the inner side surface of the door handle facing the door body, so that the 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 can be prolonged.
Each fingerprint information set may contain fingerprint information of the same user or several users, and 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 a thumb, an index finger, and a middle finger. For example, when the plurality of fingerprint heads 103 are disposed on the inner side surface of the doorknob handle, in consideration of the usual posture of a human hand when holding the doorknob, fingerprint information corresponding to the index finger and the middle finger may be set as a first priority, fingerprint information of other fingers may be set as a second priority, the collected fingerprint image may be firstly verified with the fingerprint information of the first priority, if the verification is passed, the electrically controlled door lock 102 may be controlled to be opened, and if the verification is not passed, the fingerprint image may be compared with the fingerprint information of the second priority 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 back to the door body from top to bottom. Because each fingerprint head 103 is arranged on the outer side surface of the door handle back to the door body from top to bottom in sequence, the position of each fingerprint head 103 is clear at a glance, and a user can input fingerprints directly.
In the above embodiment, the fingerprint information corresponding to the thumb may be set to a first priority level, and the fingerprint information of the other finger may be set to a second priority level; the configuration principle of the fingerprint priority is the same as that of the previous embodiment, and is considered in the consideration of the common holding posture, which is not described herein again.
In the prior art, after the door access system is installed, the position of the single fingerprint head 103 is usually fixed. However, for families living in several generations, children are short in height and often difficult to reach the position of the fingerprint head 103, and meanwhile, due to the fact that the heights of men and women may be different, the positions where the hands are naturally placed when the men and women open the doors also have a height difference, so that the user often needs to lower or raise the arm specially when verifying the fingerprint, and 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 disposed 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 may be set according to actual needs, for example, the first threshold may be set between 25 cm and 45 cm, and the distance threshold may be set between 5 cm and 15 cm.
During the concrete implementation, when being long doorknob to this doorknob, doorknob length can exceed or equal to first threshold value, can set up 2 ~ 3 fingerprint heads 103 that arrange by last to lower in proper order on the doorknob this moment, keeps certain interval between each fingerprint head 103 to make the fingerprint head 103 of different positions can adapt to different people's height, thereby realize more natural interactive effect, improve user's use and experience.
For example: the old, the couple and the children are in a family, the husband is the highest, the wife is the middle, the old and the children are shorter, and the door handle is provided with a first fingerprint head 103, a second fingerprint head 103 and a third fingerprint head 103 from top to bottom; then, the fingerprint information corresponding to the first fingerprint head 103 is concentrated to store only the fingerprint information of the husband, the fingerprint information corresponding to the second fingerprint head 103 is concentrated to store only the fingerprint information of the wife, and the fingerprint information corresponding to the third fingerprint head 103 is concentrated to store only the fingerprint information of the old and the children.
In an implementation manner of the foregoing embodiment, the access controller 101 is configured to mark, in advance, a fingerprint information set corresponding to each fingerprint head 103 as a primary fingerprint information set of the fingerprint head 103, and mark, as a secondary fingerprint information set of the fingerprint head 103, fingerprint information sets corresponding to other fingerprint heads 103 except the fingerprint head 103;
the access controller 101 is further configured to compare the fingerprint image with the primary fingerprint information set of the fingerprint head 103 when any one of the fingerprint heads 103 acquires the fingerprint image; if the fingerprint image is matched with any fingerprint information in the first-level 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 first-level fingerprint information set, the fingerprint image is compared with the second-level fingerprint information set of the fingerprint head 103, and when the fingerprint image is matched with any fingerprint information in the second-level fingerprint information set, the electronic control door lock 102 is controlled to be opened.
Specifically, if the fingerprint image is not matched with all the fingerprint information in the second-level 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 guaranteed.
In the specific implementation process, the situation that the user inputs the fingerprint at the fingerprint head 103 which is not corresponding to the user may occur, therefore, the embodiment adopts a two-stage verification mode, the collected fingerprint is verified with the first-stage fingerprint information set firstly, and the second-stage fingerprint information set is used for the second verification only under the condition that the primary verification fails, on one hand, under the condition that the user inputs the fingerprint at the corresponding fingerprint head 103, only one-time verification is performed, so that the timeliness of the fingerprint verification can be ensured, on the other hand, the second verification is performed for the situation that the user uses the non-corresponding fingerprint head 103, and the door lock can be opened when the second verification passes, thereby avoiding the situation that the user is closed outdoors due to the error of the used fingerprint head 103, and the user does not need to move to other fingerprint heads 103 for verification, which is helpful for improving the user experience.
In particular, since a user usually uses a finger print located above the door handle to perform fingerprint verification when holding the door handle, the existing single fingerprint head 103 is generally disposed at a position above the door handle. However, there are two situations when the door handle is installed: the door body is arranged on the left side door and the door body is arranged on the right side door. To the short doorknob that only has a fingerprint head 103, it is installed when opening the door left-hand or right-hand, and the position of doorknob can overturn, leads to the user to point at the collection district of fingerprint head 103 with difficulty, not only influences the use and experiences, and the substitutability of doorknob is poor moreover.
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 disposed on the door handle, and the two fingerprint heads 103 are disposed with the horizontal center line of the door handle as an axis symmetry.
Wherein the second threshold value can be between 10 cm and 25 cm.
Specifically, when being the short doorknob, the doorknob length can be less than or equal to the second threshold value, can set up 2 fingerprint heads 103 on the doorknob this moment symmetrically, no matter this short doorknob is installed on opening the door left or opening the door right, and user's fingerprint (usually the fingerprint of forefinger or middle finger) can all conveniently contact the collection district of fingerprint head 103, does not receive the influence of mounted position, possesses better substitutability.
In an implementation manner of the foregoing embodiment, the fingerprint information sets corresponding to the two fingerprint heads 103 are the same fingerprint information set.
The access control system in this embodiment has adopted the longitudinal symmetry to be equipped with the short doorknob of two fingerprint heads 103 as the fingerprint collection structure, mainly plays the effect that improves the doorknob suitability, can adopt same fingerprint information set during consequently verifying.
During the concrete implementation, all can open the entrance guard by touching arbitrary fingerprint head 103, and the touch another fingerprint head 103 also can unblank when one of them fingerprint head 103 breaks down.
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 warning information to a preset terminal when a fingerprint image acquired by any one 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 an uncommon fingerprint, such as a ring finger or little finger fingerprint; the preset terminal can be a property safety terminal, a security company terminal, a designated user mobile terminal and the like; the early warning information is used for carrying out preliminary safety early warning prompt on the preset terminal.
Specifically, when detecting that the fingerprint image is a duress fingerprint, the access controller 101 may control the electrically controlled door lock 102 to open, so as to prevent the duress person from doing a behavior that endangers the personal safety of the user, and ensure the safety of the user.
In one embodiment, the user may preset a first duress fingerprint and a second duress fingerprint, that is, the duress fingerprints may include the first duress fingerprint and the second duress fingerprint; when the door access controller 101 detects that the fingerprint image is a first coerced fingerprint, the electronic control door lock 102 is controlled to be opened, and meanwhile, early warning information is generated and sent to a preset terminal; when the door controller 101 detects that the fingerprint image is a second duress fingerprint, the early warning information is also sent, but the electric control door lock 102 is not opened. In the case of duress, the user may select to enter the first duress fingerprint or the second duress fingerprint by himself.
Further, the access controller 101 may be configured to determine that a duress event occurs when the fingerprint image acquired for the first time is the 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. Wherein, alarm information is higher than early warning information's intensity, can carry out alarm sound after sending the terminal and remind. At the moment, the system can more accurately judge whether the duress event occurs through two different duress fingerprints, so that the alarm is given in time.
In an implementation manner of the foregoing embodiment, the system further includes an outdoor ambient sound collection module and an indoor ambient sound collection module;
the door access controller 101 is further configured to open the outdoor environment sound acquisition module to acquire an outdoor environment audio when a fingerprint image acquired by any one of the at least two fingerprint heads 103 is a duress fingerprint and the electrically controlled door lock 102 is not opened; converting the outdoor environment audio into first text information; when detecting that the first character information contains dangerous words, sending alarm information to a preset terminal;
the door access controller 101 is further configured to open the indoor environment sound acquisition module to acquire an indoor environment audio frequency after a fingerprint image acquired by any one of the at least two fingerprint heads 103 is a duress fingerprint and the electrically controlled door lock 102 is opened; converting the indoor environment audio into second text information; and when detecting that the second character information contains dangerous words, sending alarm information to a preset terminal.
The outdoor environment sound acquisition module can be a sound pickup arranged in the door handle; the indoor environment sound acquisition module can be recording equipment arranged indoors and the like; the dangerous words may be preset by the user.
The system in the 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, and judge whether the duress event occurs by detecting whether dangerous words are contained in the characters, so that the alarm accuracy can be improved, and the false alarm rate can be reduced.
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 fingerprint information in the fingerprint information set; 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, a sound box and the like; the home environment configuration information may include configuration information such as indoor temperature, light intensity, fragrance, music, and the like.
Specifically, the access controller 101 may adjust an indoor home scene into a scene state preferred by the user according to corresponding configuration information preset by the user.
The system in this embodiment connects indoor intelligent home system through access controller 101, can adjust indoor house scene according to the house environmental configuration information that the user corresponds after discerning user's identity through the fingerprint to combine together access control system and indoor intelligent home system, realize better experience effect of registering one's residence.
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 fingerprint information in the fingerprint information set; acquiring a message event corresponding to 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 access control currently or other users who are not on the spot; 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 from school, a remedial class pickup reminding message can be pushed to an outside user; or when a family member enters the home, pushing a menu buying reminding message or a family member home-returning reminding message to an outside user.
After the user identity is identified through the fingerprint, the system in the embodiment pushes the message according to the message event corresponding to the user identity, so as to realize various message reminding functions.
In some embodiments, in specific implementation, when fingerprint identification fails due to insensitive fingerprint head identification or identification deviation of the access controller, the access controller may record fingerprint information of the identification failure first, and if the user inputs a matched fingerprint within a first preset time after storing the fingerprint of the identification failure, the access controller successfully releases the access control, mark the fingerprint information of the identification failure as undetermined fingerprint information, and record the occurrence frequency of the same fingerprint information to be determined. The first preset time is a short time which can be 5-60 seconds, and the pending fingerprint information recorded in the time may be the fingerprint of the user.
The access controller can monitor and update the occurrence frequency of each piece of to-be-determined fingerprint information in real time, and can also count the occurrence frequency of each piece of to-be-determined fingerprint information recorded in the time period every other preset time period; when the occurrence frequency of certain to-be-determined fingerprint information exceeds the preset frequency, the to-be-determined fingerprint information is a certain common fingerprint which is not recorded by a user but is recorded by the user or a fingerprint which is not normally identified by an access controller and is recorded by the user. At this time, the pending fingerprint information can be compared with each item of fingerprint information stored in the current fingerprint information set, and whether the fingerprint information with the similarity greater than a preset percentage with the pending fingerprint information exists or not is searched; if the undetermined fingerprint information exists, selecting the fingerprint information with the maximum similarity to the undetermined fingerprint information as target fingerprint information, and updating the target fingerprint information by using the undetermined fingerprint information, wherein the updating mode can be that the undetermined fingerprint information is used for replacing the original target fingerprint information, or the undetermined fingerprint information is fused with the original target fingerprint information to obtain new fingerprint information so as to improve the identification passing rate of a follow-up access control system on the fingerprint; if the fingerprint information does not exist, a fingerprint confirmation prompt message can be sent to the user to remind the user to confirm the fingerprint to be determined or re-input the fingerprint information.
In addition, when the occurrence frequency of certain undetermined fingerprint information exceeds the preset frequency, the access control controller can directly send a fingerprint confirmation prompt message to the user instead of comparing the undetermined fingerprint information with each item of fingerprint information stored in the current fingerprint information set, so as to prompt the user to update or confirm the fingerprint information in time, so that the probability that the access control system cannot identify the fingerprint information is reduced.
Based on the embodiment, after the entrance guard controller records the fingerprint information of the failed identification, if the user fails to detect the matched fingerprint within a first preset time length to remove the entrance guard, the fingerprint information of the failed identification is marked as risk fingerprint information, and the occurrence frequency of the same risk fingerprint information is recorded. When the number of times of occurrence of certain risk fingerprint information reaches a risk number threshold value, the entrance guard controller can send a risk early warning message to the user terminal or the property safety platform to remind the user or property management of the existence of risk personnel; during the concrete implementation, access controller can connect the monitoring camera near the outer door, and the monitoring camera is in the closed condition at ordinary times, only when the number of times that certain risk fingerprint information appears reaches the risk number of times threshold value, opens and shoots the outer region of door under access controller control to acquire the current image that contains the risk personnel image, generate the risk early warning message that contains 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 by the embodiment can also be provided with one or more standby verification modules, so that when the fingerprint head 103 fails, verification can be continued to ensure the stability and safety of the system.
It should be noted that the standby authentication modules used in the above embodiments are well-known in the art, and the contents not described in detail in this specification are well known in the art.
