The invention provides an access control device based on human body thermal induction. The access control device comprises an electric door, a power module, a collision reducing device, a limiting switch, a gravity induction carpet, a protection plate, an APM processor, rotating wheels and a loudspeaker. A storing groove is formed in the front end face of a door frame, the APM processor is mountedinside the storing groove, and the protection plate is mounted on the front end face of the storing groove through screws. Two telescopic frames are mounted on the end face of the right side of the left portion of the door frame, photoelectric switches are mounted on the front end face and the rear end face of the bottom of the door frame correspondingly, and LED light control lamps are mounted on the top of the door frame. The electric door is advantageously opened and closed by monitoring human bodies, and thus the physical output of doorkeepers is reduced; matched with the gravity induction carpet, the electric door can be subjected to double control through double power signals; and when a single device goes wrong, other devices can also open and close the electric door based on the power signals, thus the error occurrence probability is decreased, and smooth flow of personnel is guaranteed.
