Based on the face recognition access control function, a fully localized hardware system has been developed. The system takes Huawei Hi3861 main control MCU, Sipeed K210 AI chip of KANAN Technology, FPM383C fingerprint recognition module of Hailinko Electronics, PCF8574 IO module of NXP, and PN532 communication module as the main hardware structure, and Huawei open-source system OpenHarmony is the software system, optimized by deep learning algorithms to achieve safe, efficient and intelligent user access management functions. Experimental results show that the system in a variety of lighting conditions and angle changes, are able to achieve high-precision face recognition, false recognition rate of less than 0.1%, recognition time of less than 200ms, fully meet the needs of practical applications for efficient access and security management.
