It involves many new technologies such as electronics, machinery, optics, computer technology, communication technology, and biotechnology. It is an effective measure to solve the security prevention management at the entrances and exits of important departments. It is applicable to various confidential departments, such as banks, hotels, computer rooms, armories, confidential rooms, offices, intelligent communities, factories, etc. Today, with the rapid development of digital technology and network technology, access control technology has developed rapidly. The intelligent access control system has long exceeded the simple management of doorways and keys, and it has gradually developed into a complete access management system. It plays a huge role in administrative management work such as work environment security and personnel attendance management.

[0003] With the rapid development of the logistics industry, delivery personnel are the focus of monitoring in the intelligent access control system. It is necessary to identify and key monitor delivery personnel. However, how to accurately identify delivery personnel is one of the difficult problems in the existing technology. Some scenarios such as wearing clothing similar to delivery uniforms or delivery personnel going home are one of the reasons affecting the accurate identification of delivery personnel performing delivery tasks. Summary of the Invention
