Returning to the step in fig. 2, S2, the light-operated door lock receives the first identity information and performs authentication, and if the authentication passes, sends a first control signal to the video identification device.
In this embodiment, a storage medium is provided in the light-operated door lock, the storage medium stores a fingerprint identification algorithm, and when fingerprint identification authentication is required, a microprocessor in the light-operated door lock acquires the fingerprint identification algorithm from the storage medium and operates the fingerprint identification algorithm. Certainly, the storage medium can also be a cloud disk, a server hard disk and the like, when fingerprint identification authentication is needed, the microprocessor in the photon key sends an authentication request to the server, the server receives the queue authentication request and then calls a fingerprint identification algorithm in the storage medium to perform fingerprint identification queue authentication, and information with the queue authentication result is sent to the processor of the light-operated door lock.
S3, the video recognition device receives the first control signal, and acquires each second identity recognition information from the current monitoring area and verifies the second identity recognition information; and if the verification is passed, sending a second control signal to the light-operated door lock.
The monitoring area refers to the area range of the picture which can be shot by the video recognition device, and the installation range of the video recognition device can be set according to actual needs. The video identification device receives the first control signal, which indicates that the first identification information received by the current light-operated door lock passes the verification, but does not exclude the possibility that a foreign person enters the door with a formal person (carrying a photon key capable of passing the verification), so that the second identification information needs to be extracted and identified to prevent the above situation from happening. Specifically, after the video recognition device receives the first control signal, the monitoring picture in the current monitoring area can be transmitted to the face recognition module. The face recognition module compares the second identity recognition information in the monitoring picture one by one, and sends a second control signal to the light-operated door lock after the comparison is passed. The video recognition device is an electronic component with an image shooting recognition function, such as a camera.
And S4, the light-operated door lock receives the second control signal and opens the door lock switch.
And the light-operated door lock receives a second control signal, which indicates that the face information identified in the current monitoring area passes verification, so that a door lock switch can be opened.
To further enhance the security of the access control system, in certain embodiments, the method comprises: and when the second identity identification information which is not verified exists in the monitoring picture, adding identification information to the second identity identification information which is not verified. The identification information is a physical quantity that represents that "the second identification information that does not pass the verification" is different from "the second identification information that passes the verification".
The identification information may be pictures, characters, etc. For example, the second identification information is face information, the identification information may be character information added below the face information that does not pass authentication, such as "illegal face", or may be face information that does not pass the authentication by framing a frame in a regular pattern (such as a circle or a square).
In certain embodiments, the method further comprises: when the second identification information which is not verified exists in the monitoring picture, a third control signal is sent to the alarm; the alarm receives the third control signal and sends out prompt information. The prompt information includes but is not limited to: the system comprises a door lock, a door lock.
In some embodiments, obtaining and verifying each second identification information from the current monitoring area includes:
and S31, when the video recognition device judges that the number of the human bodies in the current monitoring area is 1, directly sending a second control signal to the light-operated door lock.
Generally, in a practical application process, the identification of a face image on an image frame generally includes the following steps: human body information on the image is identified based on skin color, then the human face image is screened out based on the block size, and then the screened human face image is compared with the human face image stored in advance to distinguish the human face image with successful authentication and the human face image with unsuccessful team authentication. In order to further simplify the algorithm steps of the identification process, when the video identification device judges that the number of the human bodies in the monitoring picture is 1, a second control signal is sent to the light-operated door lock. In short, when there are only 1 piece of human body information in the monitoring screen, since the first identification information (e.g., fingerprint information) has already been verified, there is no need to perform verification of the second identification information (e.g., face information).
Or, the obtaining and verifying each second identification information from the current monitoring area includes:
and S32, when the video recognition device judges that the number of the human bodies in the current monitoring area is multiple, obtaining each second identity recognition information from the current monitoring area and verifying, and if the verification is passed, sending a second control signal to the light-operated door lock.
When the number of the human bodies in the monitoring picture is judged to be multiple, even if the first identity identification information received by the light-operated door lock passes verification, the fact that someone is legal in the monitoring picture can only be explained, and whether the identities of other people are legal or not cannot be ensured. Therefore, the human face identification authentication can be carried out on all human bodies in the current monitoring picture, and the second control signal is sent to the light-operated door lock when all human faces pass the authentication, so that the light-operated door lock is opened, and the safety of the access control system is improved.
To facilitate better management of personnel, in some embodiments, the rights information includes one of the following rights information: only one door may be opened, multiple doors may be opened, or all doors may be opened. Therefore, when more personnel need to be managed, different authorities of the personnel can be prevented through authority information setting, so that the management of the personnel is enhanced. For example, for some areas with higher security level, only the authority information is set for a plurality of designated personnel, and other personnel have no access authority, thereby facilitating the management of the personnel.
In some embodiments, the access control system can be used as a security door lock to prevent external people from entering the door, and can be connected with a background attendance system to realize the collection of attendance data. Specifically, taking the example that the first identification information includes fingerprint information, after the person I sends the optical signal to the light-operated door lock, the light-operated door lock records corresponding time period information, and the time period information can be used as card punching time and sent to a background attendance system for statistics, so that the attendance statistics function is realized.
When the personnel quantity in the monitoring area is more, there may be the condition that some people's face information can't be discerned, has brought certain potential safety hazard for access control system, therefore in this embodiment, obtains each second identification information from current monitoring area and includes: when the quantity of the second identification information acquired in the monitoring area exceeds the preset quantity, the video recognition device sends the monitoring picture of the current monitoring area and the recognition effect of the second identification information to preset terminal equipment, and the recognition result comprises the second identification information which passes the verification and the second identification information which does not pass the verification.
For example, the preset number is 20, and when more than 20 faces appear in the monitored area, the video recognition device sends the captured current monitoring picture to the terminal device, preferably, the terminal device is a terminal device which is carried by a security personnel or observed in real time, and includes a mobile phone, a tablet, a personal computer, and the like. The security personnel can observe the current monitoring picture and repeatedly check the personnel information which is not verified and the personnel information which is not marked (namely, the personnel information is not judged to be verified by the video identification device and is not judged to be not verified), so that the safety of the access control system is effectively improved.
In an actual application scenario, a situation that some internal person (i.e., a person whose fingerprint and face team certificate both can pass verification) needs to take a visitor (a person whose fingerprint and face do not pass verification) to enter a door may occur, and as the face of the visitor is not entered in advance, the door lock cannot be opened. To address the above-mentioned issues, in certain embodiments, the method comprises: when the second identification information is not verified, the photon key sends the optical signal containing the first identification information to the light-operated door lock again; and the light-operated door lock verifies the first identity identification information received again, and if the verification is passed, a second control signal is sent to the light-operated door lock to unlock a door lock switch. In short, when the second identification information is not authenticated successfully, if the photon key receives the first identification information that can pass the verification again, it indicates that the insider still has to insist on unlocking the light-operated door lock on the premise that the insider knows the person who cannot pass the verification, and at this time, it can be determined that the inside person carries the guest to enter the door. Like this, through above-mentioned mode, can effectively avoid the condition emergence that external personnel still can't get into in the door under inside personnel accompany.
In certain embodiments, the method comprises: when the video identification device judges that the second identity identification information which fails in verification exists in the current monitoring area, a third control signal is sent to the alarm; the alarm receives the third control signal and sends out prompt information. The prompt information includes but is not limited to: the system comprises a door lock, a door lock.
Referring to fig. 3, the inventor provides an access control system, which includes a photon key 101, a light-operated door lock 102, and a video recognition device 103;
the photon key 101 is used for transmitting an optical signal containing first identity identification information to the light-operated door lock;
the light-operated door lock 102 is used for receiving first identity information and verifying the first identity information, and if the first identity information passes the verification, a first control signal is sent to the video identification device;
the video identification device 103 is used for receiving the first control signal, acquiring each second identity identification information from the current monitoring area, verifying the second identity identification information, and sending a second control signal to the light-operated door lock if the verification is passed;
the optically controlled door lock 102 is configured to receive a second control signal and open a door lock switch.
Further, the video identification device is used for directly sending a second control signal to the light-operated door lock when the number of the human bodies in the current monitoring area is judged to be 1; or the video identification device is used for acquiring each second identity identification information from the current monitoring area and verifying when the number of the human bodies in the current monitoring area is judged to be multiple, and sending a second control signal to the light-operated door lock if the verification is passed.
In short, when there are only 1 person, since the first identification information (e.g., fingerprint information) has already been verified, there is no need to perform verification of the second identification information (e.g., face). According to the scheme, the face features are further extracted and identified when the video identification device monitors the plurality of pieces of human body information, so that the algorithm steps of the identification process are simplified, and the identification efficiency is improved.
