Embodiment Construction

[0084] A system 1 for detecting a target object, in particular for detecting an item comprising bulky ferromagnetic material such as an assault rifle, said system comprising:

[0085] - at least one first and second detector 10, 20 together forming a gate,

[0086] - at least one processing unit 6, and

[0087] - at least one communication interface 7 .

[0088] Each detector 10 , 20 comprises at least one magnetic sensor 5 . The term "magnetic" (or magnetostatic) is here understood to mean a passive sensor configured to detect the magnetic field naturally surrounding an object containing iron or any ferromagnetic composition, as opposed to, for example, an induction coil .

[0089] More precisely, the first detector 10 comprises at least one first magnetic sensor 5 , preferably at least two, for example three first magnetic sensors 5 , while the second detector 20 comprises at least one second magnetic sensor 5 . Preferably, the second detector 20 and the first detector 1...

Abstract

The invention relates to a system for detecting a target object, comprising: a first detector (10) that has at least a first magnetic sensor (5) and at least one transmitter (8), a second detector (20) which differs from the first detector (10) and comprises at least one second magnetic sensor (5) and at least one transmitter (8), and at least one processing unit (6) configured to receive the signals which indicate an intensity of a magnetic field detected by the first magnetic sensor (5) and / or the second magnetic sensor (5), and a communication interface (7) which is configured to transmit the signal generated by the first and / or the second magnetic sensor (5) to the processing unit (6), said processing unit (6) being configured to send instructions to generate an alarm to the transmitter (8) of the first detector (10) and / or the second detector (20).

Description

technical field [0001] The present invention relates to the field of target object detection, and more particularly to the detection of objects containing magnetized or ferromagnetic components. Background technique [0002] The current climate caused by various attacks in public places has led to the need to detect assault rifle-like weapons at the entrances of public places such as stadiums, concert halls, department stores, etc. [0003] Currently, such detection is usually performed by security personnel equipped with manual portable detectors that are moved along the body and around the belongings of persons wishing to enter the various public spaces concerned. However, such inspections are lengthy and tedious, and the number of people wishing to enter the premises is often too great to carry out the inspection in a satisfactory manner. [0004] There have also been proposals to install permanent gates at the entrances to various public spaces. These doors are suitabl...
