In view of the need for dynamic mask wearing recognition in the current social environment, this paper aims to design an embedded dynamic face mask recognition patrol system to realize the functions of obstacle avoidance patrol, dynamic face recognition, wireless networking and operation between modules. Detailed design was carried out for face mask wearing recognition, precise reminder and persuasion of pedestrians, dynamic line planning, wireless control and information transmission of automatic obstacle avoidance patrol. This study provides a theoretical basis for realizing the mode of multi‐integration and improving the use value of robots in various complex environments.
