METHOD FOR FINDING MOVING ELECTRO-CONDUCTIVE OBJECTS Russian patent published in 2007 - IPC G08B13/24 

FIELD: safety technologies, possible use for finding moving electro-conductive objects.

SUBSTANCE: in accordance to invention, in controlled area of space along the protected boundary at similar or different distances from each other, emitters interconnected by communication cable are mounted, made in form of transformers of electric voltage to electromagnetic field, and measuring devices interconnected by another communication cable, in which devices for primary analysis and processing of measured changes of electromagnetic field parameters are positioned, "measuring device - emitter" pairs are created from adjacent measuring devices and emitters and from measuring devices and emitters adjacent to these measuring devices and emitters, pairs are identified and information about detection of electro-conductive object, generated by each pair, is transferred to central device for analysis and processing of information, which generates a notification about detection of electro-conductive object or group of electro-conductive objects with indication of detected location.

EFFECT: increased trustworthiness of object detection.
