Patent ID: 7394365

Claim:
Method for detecting and monitoring events on a pre-determined territory, comprising the use of at least a directional sensor ( 1 , 1 ′, 1 ″) and at least a relevant device for moving said at least directional sensor ( 1 , 1 ′, 1 ″) with a first canonical rotation about a vertical axis ( 2 ) of an angle between 0° and 360° and a second canonical rotation of an angle (α) between 0° and 90 about an horizontal axis perpendicular to the laying direction of said at least one directional sensor ( 1 , 1 ′, 1 ″), the method comprising the step: A. dividing said first rotation in a first number of first angular sectors and said second rotation in a second number of second angular sectors so as to divide the territory into ring sectors (RS); the method being characterized in that it further comprises the following steps: B. scanning the whole predetermined territory, at regular time intervals, in order to individuate alterations of predefined chemical-physical parameters with respect to a set of reference values thereof; C. between the time intervals of step B, scanning the ring sectors (RS) wherein said alterations have been individuated, with at least a first frequency of scanning; the territory being so cyclically scanned by step-by-step directing said at least a directional sensor (1,1′,1″) towards one or more of said ring sectors (RS), detection of an event occurring by comparison of detected instantaneous values with a predetermined set of reference values for one or more chemical-physical parameters in said territory.
