The specific use mode is as follows: when a visitor needs to visit a certain area, the visitor contacts with an addressee in advance, and selects a passing mode suitable for the visitor from three modes of license plate recognition, face recognition and two-dimensional codes. When the license plate recognition mode is adopted, a license plate number needs to be provided for an addressee, when the face recognition mode is adopted, a temporary photo needs to be provided for the addressee, and when the two-dimensional code mode is adopted, information does not need to be provided for the addressee. And after the interviewee agrees, the license plate number or the photo is submitted to the cloud platform server through the WeChat public number or the applet of the interviewee. Or applying for an encrypted and time-efficient passing two-dimensional code through the cloud platform server. The passing two-dimensional code has certain timeliness on the cloud platform server, and can automatically fail after a certain time. And the interviewee sends the passing two-dimensional code to the visitor. In the later stage, only the two-dimension code scanning head 2 is needed to scan the passing two-dimension code, and whether the passing result is allowed or not is obtained to determine whether the passing gate is opened or not through the gate control interface 181.

When a visitor arrives at an entrance guard passage opening and a license plate recognition mode is adopted, a camera on the license plate recognition gun 4 uploads a license plate number picture of the visitor to a license plate recognition algorithm module. The license plate recognition algorithm module recognizes that the license plate number is transmitted to the CPU core module 11 on the gate control main board 1 through a third cable. Meanwhile, the cloud platform server transmits the encrypted license plate number allowing passage to the communication encryption and decryption module 14 through any one of the Ethernet interface, the 4G wireless communication module and the WIFI communication module, and the license plate number allowing passage 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 license plate number stored in the license plate number storage unit that is legitimate. The result of whether to permit passage is derived to decide whether to open the passage gate through the gate control interface 181.

When the visitor adopts a face recognition mode, the visitor aims the face at the face recognition camera 31. The face recognition camera 31 transmits the shot face picture to the face recognition algorithm module, and the face recognition algorithm module 19 analyzes valid face feature data and transmits the data to the CPU core module 11. The cloud platform server transmits the encrypted picture allowing passage to the communication encryption and decryption module 14 through any one of the ethernet interface, the 4G wireless communication module and the WIFI communication module. The picture information 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 transmits the received passthrough photo information and the face feature data to the image contrast algorithm module. And the image comparison algorithm module compares and analyzes the photo information and the human face characteristic data to judge whether the photo information and the human face characteristic data are the same person. The image comparison algorithm module transmits the result of the comparison to the CPU core module 11. The CPU core 11 determines whether to open the pass gate through the gate control interface 181 according to the comparison result.
