METHOD OF CONTROLLING GUARDED OBJECTS Russian patent published in 2009 - IPC G08B25/10 G08G1/123 

FIELD: process engineering.

SUBSTANCE: invention relates to security equipment. During preparatory stage, distinguishing features of guarded objects are memorised, amount of elementary reference zones is determined, values of reference primary spatial-and-data parametres (PSAP) are calculated for all M direction-finding stations relative to known location coordinates of the centers of each n-th elementary reference zone, n=1, 2,…, N. In operation, when alarm signal is received from mobile guarded object via m direction-finding stations, PSAPs are measured at each aforesaid station, PSAP is transmitted to central control station. n-differences between reference and measured PSAP are calculated for every elementary reference zone to define minimum magnitude. Coordinates of elementary reference zone centers are taken to be coordinates of movable guarded object. Simultaneously, alarm signal is decoded at central control station; data on distinguishing features of guarded object are selected and identified with those memorised earlier. Task unit is sent into defined reference zone for search of guarded object that transmitted alarm signal.

EFFECT: reduced time of guarded object search.
