Embodiment Construction

[0028] Exemplary embodiments of the present invention are described below with reference to the accompanying drawings.

[0029] Figure 1A is the schematic diagram, Figure 1B is the floor plan, Figure 1A and Figure 1B Shown is the structure of a baggage control gate installed at the entrance of a controlled area where bringing in or out of a predetermined object is prohibited.

[0030] The carry-on control door is set to face the channel 14 leading to (access) control area, and includes: entrant information reading device 21, leaver information reading device 31, magnetic field change detection device 11, controller 12, entrant movement Sensor 23 , leaver motion sensor 33 , server 13 and switching device 22 . The entrant information reading device 21 and the leaving person information reading device 31 read personal information of passers-by. The magnetic field change detection device 11 for entrants and exiters forms an alternating magnetic field in the passage 14, and ...

Abstract

The invention discloses a carrying object control door, which includes a first reading device, a second reading device, a detection device, a judgment unit, a first opening and closing device and a second opening and closing device. The baggage control door controls the baggage that is restricted from being taken into or out of a predetermined area. Sequentially arranged along the entry direction from the passage into the control area for controlling carried objects: a first reading device, a second opening and closing device, a detection device for the first and second persons, a first opening and closing device and a second Reading device.

Description

technical field [0001] The present invention relates to a carry-on control gate that detects a change in a magnetic field due to magnetization reversal of a magnetic material exhibiting the large Barkhausen effect, and that is controlled to be limited in or out Carrying items for the intended area. Background technique [0002] For example, Patent Document 1 (JP-A-2003-182847) discloses a baggage control gate that uses a magnetic material exhibiting the large Barkhausen effect to detect the passage of carry-on or alarm. [0003] It is already known that soft magnetic materials such as Fe-Co-based amorphous metal wires are magnetic materials exhibiting the large Barkhausen effect. When an alternating magnetic field stronger than the coercive force is applied to a magnetic material, the magnetization of the magnetic material reverses rapidly, which results in a change in the magnetic field. When a magnetic material exhibiting the large Barkhausen effect is added to an objec...
