Abstract
A system for detecting a target object, comprising: a first and a second detector which have magnetic sensors configured to detect a magnetic field and to generate a signal which indicates a magnetic field intensity; a processing unit configured to receive the signals which indicate an intensity of a magnetic field detected by the sensors (5), and a communication interface which is configured to transmit the signals generated by the magnetic sensors to the processing unit, the processing unit additionally being configured to determine an average value of the signals generated by the magnetic sensors of the first and second detectors and, when said average value is greater than a predetermined threshold value, to send instructions for generating an alarm.

A detection system comprising:
- a first detector comprising a first magnetic sensor configured to generate a first signal, wherein the first signal is representative of an intensity of a detected magnetic field;
- a second detector separate from the first detector and comprising a second magnetic sensor configured to generate a second signal, wherein the second signal is representative of an intensity of a detected magnetic field;
- a processing unit configured to receive the first and second signals and to determine an average value of the first and second signals and, when said average value is greater than a predetermined threshold value, to send instructions to generate an alarm;
- and
- a communication interface configured to transmit at least one of the first and second signals to the processing unit.
A detection method comprising the following steps:
- S1:
- generating a first signal with a first magnetic sensor of a first detector and a second with a second magnetic sensor of a second detector, wherein the first signal and the second signal are representative of an intensity of a magnetic field;
- S2:
- computing an average value of the first and second signals;
- S4:
- comparing the average value with a predetermined threshold value;
- and
- S5:
- when the average value is greater than the predetermined threshold value, sending instructions to generate an alarm.
