CONTROL METHOD OF ANTENNA-MAST STRUCTURES Russian patent published in 2019 - IPC G01B21/22 

FIELD: antenna and mast structures.

SUBSTANCE: invention relates to control of antenna structures of antenna-mast structures (AMS), rapid notification of changes in their state, prevention of emergency situations and can be used in automated systems for monitoring the state of antenna-mast structures. According to the antenna-mast structures status control method, consisting in the unit installation on its mast with the triaxial accelerometer, installation on it, through equal distances, blocks with triaxial accelerometers, installation of anemometer, installation in its preset sections of stress-strain state sensors, installation of unit with triaxial accelerometer in its foundation and seismic sensor in soil, collection and processing of measurement data, wherein in addition along the mast sensor optical fibers are laid, in parallel to which optical fibers are laid with fiber-optic Bragg gratings included in them, by methods of Brillouin optical reflectometry and / or other optical reflectometry methods, distributions of stress-strain states of AMS elements along sensor optical fibers are measured, calibrating obtained distribution curves of stress-strain states based on processing results of optical signals reflected on fiber-optic Bragg gratings, and then in online mode based on results of processing measurement data, AMS state and reasons of possible deviations of AMS state parameters are evaluated.

EFFECT: essence of the present invention is expansion of the field of application.
