The invention provides a control device of a human body self-service security detection access system. The control device comprises a box body, a human body scanning imaging area and a single-person pass control area are sequentially arranged in the box body, wherein a human body is scanned and detected in the human body scanning imaging area by using electromagnetic waves to obtain a human body image with certain accuracy, and the human body image is compared with preset image information of a main control module to judge whether the human body has entry or exit permission; in the single-person pass control area, after the main control module judges the scanning result of the human body scanning imaging area, a single person is controlled to enter or is prevented from entering through a gate machine; and the human body scanning imaging area comprises a magneto-optical image recognition scanning module, and the magneto-optical image recognition scanning module scans and detects the human body using the electromagnetic wave characteristics between mid-infrared waves and microwaves in an electromagnetic wave spectrum to generate a set of complete clear image of a front face of the human body+ a back surface of the human body, and to see through the shape and material information of items in the clothing.
