Abstract

The invention relates to a passing-through type specific metal detecting door which comprises a door head main control box and two side door plates. The door head main control box is connected with the upper end of each of the two side door plates for forming a detecting channel. The door head main control box comprises a microcontroller, a data memory, a signal output circuit, a signal acquisition circuit, a display screen and a power supply. Each side door plate comprises a sensor board, a detecting area and a warning lamp. The detecting area is internally provided with an electromagnetic induction coil, a receiving coil and a calibration coil. According to the passing-through type specific metal detecting door, because the electromagnetic induction coil, the receiving coil and the calibration coil are arranged in the detecting area, the electromagnetic induction coil generates a detecting magnetic field which covers the detecting area; different kinds of metal generate different secondary magnetic fields in the detecting magnetic field because of an eddy current; the receiving coil receives the magnetic signal of the secondary magnetic field and transmits the corresponding electric signal to the microcontroller; and performing warning by the microcontroller according to the electric signal with a specific magnitude, thereby realizing warning on specific forbidden metals.

Description

technical field [0001] The invention relates to the technical field of security inspection equipment, in particular to a pass-through specific metal detection door. Background technique [0002] Metal detection gates, also known as metal security gates, are widely used in airports, stations, customs, courts and other public places to detect metal objects hidden on the human body. Items that threaten public safety, such as knives and firearms. The pass-through metal detection door usually consists of the left and right door panels and the main control box of the door head to form a detection channel. The left and right door panels are equipped with transmitting coils capable of generating alternating magnetic fields and receiving coils for inductive magnetic field signals. In the main control box of the door head The interior is equipped with related circuits such as control detection and alarm display unit. The control circuit applies an alternating current to the transmit...
