A transmission device of a millimeter wave security detector

Abstract

The present invention provides a transmission device for a millimeter wave security inspection device, which includes a driving mechanism and a millimeter wave detection mechanism; Millimeter wave detection mechanisms are respectively installed inside and are symmetrical to the transverse central axis of the conveyor belt body. Drive the human body to move forward at a uniform speed through the conveyor belt body, and use the active millimeter-wave detection components on the left side of the security inspection bearing plate to conduct security inspections on the left and right ends of the front side of the human body, which can make the security inspection more accurate. When the conveyor belt body moves to position A , the plastic rack drives the upper driven gear to rotate 90° clockwise, so that the security inspection bearing plate rotates 90° counterclockwise, and performs security inspection on the right ends of the back of the human body. When the conveyor belt body moves to position B, the plastic rack three drives The lower driven gear rotates 90° counterclockwise, so that the security check bearing plate turns 90° clockwise again to return to its position.

Description

technical field [0001] The invention belongs to the technical field of millimeter wave security inspection, and more specifically relates to a transmission device of a millimeter wave security inspection instrument. Background technique [0002] The millimeter-wave body security imager uses the penetration ability of millimeter-wave to image ordinary clothes, so as to determine whether there are suspected items hidden on the body surface of the inspected body. It has fast scanning imaging speed, comprehensive security inspection, safety and reliability, privacy protection, and automatic identification of contraband. Features. The advantages of the millimeter-wave body security imager are very obvious. It can not only detect metals, but also detect non-metals, explosives, etc., and has better image contrast and spatial resolution capabilities, and can display the location and shape of hidden objects. Compared with X For optical security detectors, millimeter waves are harmle...
