And 106, the intelligent screen sends an unlocking instruction to the intelligent lock, so that the intelligent lock is unlocked according to the unlocking instruction.
Wherein, establish the bluetooth and be connected the back at the smart screen with the intelligent lock, the smart screen just can send the instruction of unblanking to the intelligent lock through the bluetooth, and the intelligent lock is unblanked according to this instruction of unblanking completion. The intelligent lock is in the in-process of unblanking according to the instruction of unblanking, need extract the specific information in the instruction of unblanking, adopts and draws with the corresponding mode of intelligent screen generation instruction of unblanking.
Through above-mentioned access control method, through the separation of intelligent screen and intelligent lock to through the bluetooth communication of low-power consumption, further make the intelligent lock be in the state of treating awakening up under the condition of not unblanking, greatly improved the duration of intelligent lock.
As shown in fig. 2, in an embodiment, after the authentication is successful, the smart screen wakes up the smart lock and establishes a connection, including:
The bluetooth broadcast is a broadcast message based on bluetooth. According to a Bluetooth communication protocol, the intelligent lock in the low power consumption mode can capture a Bluetooth-based broadcast message sent by the intelligent screen, so that the intelligent lock is awakened, and the state is updated to a normal working mode.
And step 204, the intelligent screen establishes a low-power-consumption Bluetooth connection with the intelligent lock after awakening the intelligent lock.
The intelligent lock completes pairing according to data information in the captured Bluetooth-based broadcast message, and therefore the intelligent screen is connected with the intelligent lock through the low-power-consumption Bluetooth.

The intelligence screen sends the instruction of unblanking to the intelligence lock for the intelligence lock unblanks according to the instruction of unblanking, include:
and step 306, the intelligent screen sends an unlocking ciphertext to the intelligent lock through the Bluetooth, so that the intelligent lock receives the unlocking ciphertext, decrypts the unlocking ciphertext by using a key matched with a preset key, and unlocks after confirming that the decrypted information is valid.
After Bluetooth communication is established between the intelligent screen and the intelligent lock, the intelligent screen sends the generated unlocking ciphertext to the intelligent lock through Bluetooth, and the intelligent lock is provided with a key matched with a preset key. There are two categories in key encryption, namely asymmetric encryption: the encryption and decryption adopt two keys corresponding to each other, namely a public key and a private key, and the other one is symmetric encryption: the encryption and decryption both adopt private keys, and the same two encryption modes can also be adopted in the invention. If the asymmetric encryption is adopted, the intelligent screen encrypts an unlocking plaintext by using a public key to generate an unlocking ciphertext, and the intelligent lock decrypts the unlocking ciphertext by using a corresponding private key; similarly, if symmetric encryption is adopted, the intelligent screen encrypts the unlocking plaintext by using the private key to generate an unlocking ciphertext, and the intelligent lock decrypts the unlocking ciphertext by using the same private key.
The intelligent lock acquires unlocking information after decryption is completed, whether unlocking requests and equipment information in the unlocking information are valid or not is judged, and if yes, unlocking is carried out. The equipment information mainly refers to MAC address information of the intelligent screen, the MAC address information corresponding to the intelligent screen is prestored in the intelligent lock, and if the MAC address information obtained through decryption and the prestored mismatching description are not unlocking ciphertexts sent by the corresponding intelligent screen, unlocking is not carried out.

And step 404, the intelligent screen sequentially performs living body detection and face matching according to the target face.
After the face information in the video stream is acquired, the acquired face information needs to be detected, wherein the detection includes living body detection and face detection. The live body detection is to detect whether or not a human face appearing in a video stream is a real person, not a photograph, a video, or the like. The living body detection also adopts a CNN neural network, the extracted human face is sent into the CNN neural network to obtain a living body confidence coefficient, and if the confidence coefficient exceeds 0.5, the living body is considered as the living body. And if the living body detection is successful, carrying out face matching, wherein the face matching also adopts a CNN neural network, matching the extracted face with the pre-stored faces in a face library, obtaining the similarity between the extracted face and each face in the face library through comparison, and if a face with the score corresponding to the similarity exceeding 0.9 exists, successfully matching.

And step 504, if the smart screen detects that the failure times exceed the preset times within the preset time, generating an abnormal event and pushing the abnormal event to the mobile terminal.
The preset times are failure limit times preset in the intelligent screen, specifically include living body detection failure times and face matching failure times, and the living body detection and the face matching are independent and have a sequence, so that the failure times only occur in practice, for example, when the living body detection fails for multiple times and reaches the preset times, the process is directly ended, and the face matching process is not performed any more; and if the living body detection is successful after multiple failures (the number of times does not exceed the preset number), the counting is returned to zero, and the face matching is carried out and the counting is carried out again. In addition, the number of statistical failures is within a preset time range, such as 1 minute, 30 seconds, etc.; and if the preset time is exceeded but the failure times are not preset times, the timer is counted again and counted. In one embodiment, all the failure times of continuous detection of the same face information are counted, and if all the failure times exceed the maximum limit, the counting is not counted again.
If the failure times counted in the preset time reach the preset times, generating an abnormal event and pushing the abnormal event to the mobile terminal, and locking the screen for a preset stop time, wherein the preset stop time can be 1 minute, 30 seconds and the like.
By counting the failure times, generating the abnormal event according to the failure times and feeding the abnormal event back to the mobile terminal, the user can know the current relevant condition of the current front door in real time, so that the processing is convenient in time, and the safety is improved.

The failure times in this embodiment may be the living body detection failure times or the face matching failure times, or may be the sum of the two failure times.
And step 604, if the failure times detected by the intelligent screen exceed the preset alarm times, sending alarm information to the community property platform in real time.
In this embodiment, the time range may not be considered in the failure times counting, all failure records of a certain face on the time axis are counted, and when the total number of the failure times reaches the preset alarm times, the face is sent to the community property platform, so that the community property records the face. In another embodiment, the time range may also be considered, a preset alarm time is set, and after the preset alarm time exceeds a second preset alarm time, alarm information is sent to the property of the cell in real time, so that the property of the cell can eliminate danger in time. The alarm information includes detected face information and time information corresponding to the number of failures.
By recording failure times and sending alarm information to the community property platform, the security system is perfected, and living safety is fully guaranteed.
