Metal security check door with movable detection function

Abstract

The invention discloses a metal security check door with a movable detection function. The metal security check door comprises a door frame; the metal security check door further comprises a slide rail, a slider, a transmission mechanism, a driving circuit, a linear motor, a wireless receiving circuit, an induction probe, an oscillation circuit, a control circuit and a voice alarm circuit; the slide rail is fixed at the inner side of the door frame; the slider is movably fixed on the slide rail through the transmission mechanism; the induction probe is fixedly arranged on the slider; the linear motor is used for generating a driving force according to driving signals, so that the transmission mechanism can drive the slider to move up and down on the slide rail; the induction probe is used for obtaining induction signals through detection; the oscillation circuit is used for obtaining oscillation signals; the control circuit is used for processing received oscillation signals and judging whether a metal object exists; and the voice alarm circuit is used for voice alarm. According to the metal security check door of the invention, the detection height and range of the induction probe can be adjusted according to different heights, so that detection is more sensitive, and detection efficiency can be improved.

Description

technical field [0001] The invention relates to a movable detection metal security inspection door, which belongs to the technical field of metal detection. Background technique [0002] Metal security gate is a commonly used equipment in security equipment. A device that can generate an alarm when a human body carries metal objects through, and can accurately detect metal objects or objects containing metal carried by a person or in a hand bag, such as various controlled knives, weapons, metal products, electronic products and others Items containing metal, etc. [0003] With the rapid development of economy and society, the current population mobility in our country has been greatly enhanced. In order to maintain public safety, standard channel-type security gates have been installed in most public places such as airports, railway stations, bus stations, theaters, stadiums, and subway entrances. Used to check hidden metal objects on the human body. In addition, enterpri...
