METHOD FOR DETECTING PENETRATION THROUGH FORBIDDEN ZONE CONTOUR AND DEVICE FOR REALIZATION OF SAID METHOD Russian patent published in 2005 - IPC

FIELD: alarm signaling devices.

SUBSTANCE: method includes registration of signals, determining values of physical parameter of soil, taken in from sensors, positioned in soil along aforementioned contour, taking decision about detection of penetration through aforementioned contour in case of deviation of determined values of physical parameter of soil from standard values. As sensors, galvanically grounded electro-conductive bodies are used - electrodes, and as physical parameter of soil - seeming specific electric resistance of soil R_k in different points along vertical line along contour. Device for detecting penetration through contour of forbidden zone has multiple sensors, positioned along contour of forbidden zone and processor with memory block. Device additionally has electric current generator, electric current measurement means, electric voltage meter, first commutator and second commutator, and aforementioned sensors are made in form of electrodes buried in soil.

EFFECT: higher efficiency, broader functional capabilities.
