Mobile face recognition access control device
ActiveCN223006468UCharacter and pattern recognitionIndividual entry/exit registersControl theoryMechanical engineering
The utility model provides a movable face recognition access control device, and relates to the field of face recognition access control, a groove is formed in the left side of a fan and used for air intake, a groove is formed in the bottom end of the interior of a controller, air pipes are fixedly connected to the interior of the groove in a linear array mode, and main bodies of the air pipes are of inclined structures; and the air pipe is connected with a fan fixedly connected to the left end surface of the controller, so that the problems that the application range is limited, the function is relatively single, mobile patrol cannot be carried out and the like due to the fact that the existing access control identification equipment is usually placed at a gate machine, a gate and the like in a fixed manner are solved; the recognition lens can be used by adopting a CCD (Charge Coupled Device) structure, information of visitors can be recognized through the lens with the CCD structure, and whether the access control system is opened or not is judged by comparing the information with the controller or the cloud, so that the aim of precise recognition is fulfilled.
