In order to meet the requirements of integrated management of electronic lock with high security and high convenience in application scenarios such as data center network cabinet, a lock control system based on biometric technology is designed, which integrates electronic lock, network controller, collector and lock control platform. Platform management is used for system integration. By constructing dual MCU system of electronic lock ESP32-C3FH4 and network controller CH32V307VCT6, and integrating system data into biometric electronic lock, electronic lock adopts modular design to meet different functional requirements. The lock-control system realizes face and fingerprint template transmission, authentication information and event management through wireless and wired network communication. The existing Modbus TCP communication protocol is upgraded, and MODBUS protocol is extended to UDP communication, so as to realize the transmission of large throughput data. Through the test of the lock-control network management platform, the network controller can realize the centralized management of 8 lock information, and realize the authentication and permission change of operation and maintenance personnel through the collection and uploading of biometric information such as face and fingerprint. The test face module prosthesis resistance rate of 100%, face in vivo detection reception rate of 99.71%, from trigger to single face, fingerprint recognition, unlocking time is less than 2.5 seconds. The system expands the application of biometric electronic lock in industrial field.
