FIELD: methods of security monitoring of area.
SUBSTANCE: invention relates to methods of security monitoring of area and can be used in cases of signaling control of vantage ground, movement along which is possible in any directions, detachable finders, determining the distance to the spot of rupture of microwire based on reflectometry method. Method consists in determining external borders of protected vantage ground in the form of rectangle; deployment of two detachable finders so that their microwires lay on two diagonals of this vantage ground; ensuring transfer of alerts from detachable finders on system of collecting and processing of information at breakage by violator of microwire; determination of waiting time for the second alert depending on the length of larger side of the rectangular vantage ground and the minimum possible speed of violator; transfer together with alerts from detachable finders to a system of collecting and processing values of lengths of microwires parts, remaining connected to detachable finder; application of algorithm for determining the trajectory of violator, in which trajectory is defined as a vector connecting the deployment scheme of detachable finder on the ground ends of microwire remaining connected to detachable finder; construction of vector, beginning of which is the end of microwire of detachable finder, which transmitted the alert first. Method includes a preparatory stage with deployment of microwire through vantage ground terrain according to established scheme and the main stage, which begins with the detection of violator and ends with the determination of its trajectory.
EFFECT: technical result of the invention is to obtain the possibility of determining trajectory of detected violator, reducing the length of deployed microwires, reducing time required for deployment of microwire on the ground.
