Design of Laboratory Cloud Visual Intercom Access Control System Based on NFC Technology

Nowadays, the commonly used laboratory access control system is unable to quickly authenticate a large number of identities due to technical limitations. In order to solve this problem, a laboratory cloud visual intercom access control system based on NFC technology is designed. Based on the hardware part of the original access control system, designed the hardware module of NFC card reader, door machine and indoor unit. Based on the designed hardware, the software part of the system is designed. In order to ensure the security of communication between cloud server and access control terminal, AES algorithm is used to encrypt the communication. The cloud platform is used to realize the function of the access control system, and the design of the laboratory cloud visual intercom access control system is completed. By testing the load capacity and operation sensitivity of the system, the superiority of the system performance is verified.
