METAL DETECTOR INTEGRATED WITH SITE-EXISTING PATHWAY

A method and system for utilizing a site−existing pathway for monitoring and preventing access to or egress from a designated area by a source of a threshold amount of metal. The system comprises one or more field coil modules, a power supply module, one or more field coil modules, and an electronics module, all interconnected with one another. The field coil modules are adapted for placing in a location which does not restrict the pre−existing pathway, but which utilizes the pathway to appropriately position the source of metal in a detection zone for effectively searching the source. The electronics module is adapted to receive and process an electrical signal from the one or more field coil modules, to indicate whether the threshold amount of metal has been detected, and to prevent access or egress from the designated area.

La présente invention concerne un procédé et un système qui permettent d'utiliser un chemin de circulation présent sur un site afin de surveiller et d'empêcher l'accès à une zone spécifiée ou la sortie de cette dernière, par une source d'une quantité limite de métal. Le système comprend au moins un module de bobine de champ, un module d'alimentation en puissance et un boîtier électronique qui sont tous interconnectés les uns aux autres. Les modules de bobines de champ sont adaptés pour être placés dans un endroit qui ne restreint pas le chemin de circulation préexistant, mais qui utilise le chemin de circulation pour positionner de manière appropriée la source de métal dans une zone de détection afin de détecter efficacement la source. Le boîtier électronique est prévu pour recevoir et traiter un signal électri
