OPEN METAL DETECTOR Russian patent published in 2023 - IPC G01R33/12 

FIELD: metal detection.

SUBSTANCE: detection system based on continuous radiation for detecting metal objects consists of a transmitting unit containing transmitting coils (Tx1,…,Txm) and the first clock generator, the receiving node containing the receiving coils (Rx1,…,Rxn) located in a separate second column, and a second clock generator, a detector configured to detect the zero crossing moment by a set of electrical signals of the transmitting node and the receiving node, a signal generator configured to generate a phase alignment signal synchronized with this zero crossing moment, and a wireless communication interface configured to transmit a respective phase alignment signal for phase alignment of the first clock generator and the second clock generator.

EFFECT: creation of a detection system based on continuous radiation for detecting metal objects, which can be quickly deployed and dismantled in a given area, while ensuring the detection of metal objects with a reduced number of false triggering.
