[0022] The gate control interface module 18 includes a transistor Q3, a resistor R43 connected to the B pole of the transistor Q3, a light-emitting diode D8 connected to the C pole of the transistor Q3 and a resistor R38 connected to the light-emitting diode D8, a relay K1 connected to the C pole of the transistor Q3, and a voltage regulator D7 connected to the C pole of the transistor Q3. The resistor R43 is connected to the CPU core module 11, the relay K1 is connected to the gate control interface 181, and the E pole of the transistor Q3 is grounded.

[0023] The CPU core module 11 includes a CPU chip, and the model of the CPU chip is STM32F207VCT6.

[0024] The image comparison algorithm module 13 includes an image comparison algorithm chip, and the chip of the image comparison algorithm chip is STM32F405.

[0025] The gate control mainboard 1 is electrically connected to the cloud platform server via any one of Ethernet communication, 4G wireless communication and WIFI communication to achieve communication. The cloud platform server is electrically connected to the WeChat public account or mini program.

[0026] Specific usage: When a visitor needs to visit a certain area, he or she will contact the interviewee in advance, and the visitor will choose a suitable access method from the three methods of license plate recognition, face recognition and QR code. When the license plate recognition method is used, the license plate number needs to be provided to the interviewee. When the face recognition method is used, a temporary photo needs to be provided to the interviewee. When the QR code method is used, no information needs to be provided to the interviewee. After the interviewee agrees, the license plate number or photo is submitted to the cloud platform server through the interviewee's WeChat official account or mini program. Or apply for an encrypted and time-sensitive pass QR code through the cloud platform server. The pass QR code has a certain timeliness on the cloud platform server and will automatically expire after a certain period of time. The interviewee sends the pass QR code to the visitor. Later, it is only necessary to use the QR code scanning head 2 to scan the pass QR code to obtain the result of whether to allow passage to decide whether to open the pass gate through the gate control interface 181.

[0027] When a visitor arrives at the access control passage, using the license plate recognition method, the camera on the license plate recognition gun 4 of the present invention will take a photo of the visitor's license plate number and upload it to the license plate recognition algorithm module. The license plate recognition algorithm module recognizes the license plate number and transmits it to the CPU core module 11 on the gate control mainboard 1 via a third cable. At the same time, the cloud platform server transmits the encrypted license plate number that is allowed to pass to the communication encryption and decryption module 14 through any one of the Ethernet interface, 4G wireless communication module, and WIFI communication module. The license plate number that is allowed to pass is decrypted by the communication encryption and decryption module 14 and then transmitted to the CPU core module 11. The CPU core module 11 compares the recognized license plate number with the legal license plate number stored therein. The result of whether to allow passage is obtained to decide whether to open the access gate through the gate control interface 181.

[0028] When a visitor uses facial recognition, they aim their face at the facial recognition camera 31. The facial recognition camera 31 captures the facial photo and transmits it to the facial recognition algorithm module. The facial recognition algorithm module 19 analyzes the valid facial feature data and transmits this data to the CPU core module 11. The cloud platform server transmits the encrypted, pass-through photo to the communication encryption and decryption module 14 via any one of the Ethernet interface, 4G wireless communication module, and Wi-Fi communication module. The pass-through photo information is decrypted by the communication encryption and decryption module 14 and then transmitted to the CPU core module 11. The CPU core module 11 transmits the received pass-through photo information and facial feature data to the image comparison algorithm module. The image comparison algorithm module compares and analyzes the photo information and facial feature data to determine whether they are the same person. The image comparison algorithm module transmits the comparison results to the CPU core module 11. Based on the comparison results, the CPU core module 11 decides whether to open the access gate through the gate control interface 181.

[0029] In summary, the present invention is provided with a QR code scanning head, a face recognition camera 31 and a license plate recognition gun 4, which can realize three access modes: license plate recognition, QR code recognition and face recognition. Users can use different access modes to enter and exit a certain area. The present invention has a good solution for the passage of temporary visitors and permanent staff. For temporary visitors, you can use the appointment function of the WeChat public account or the mini program to upload the visitor's photo or license plate number in advance. If you need to pass by using a QR code, you can also generate a time-sensitive pass QR code in advance. When a visitor arrives at the access control gate, he can use any one of the methods of face recognition, license plate recognition and QR code recognition to pass, which is extremely convenient to use. In addition, the present invention has the advantages of scientific and reasonable structure, simple and convenient operation, high safety and convenience.
