SNOW LOADS MONITORING METHOD ON BUILDINGS COVERS USING UNMANNED AERIAL VEHICLES Russian patent published in 2020 - IPC G01W1/14 E04D15/00 

FIELD: aviation.

SUBSTANCE: invention relates to monitoring of condition of building structures. Method of snow load monitoring on buildings covering with application of UAV includes stages of remote determination of average height of snow cover h_s and average design density of snow taking into account its layered structure ρ_s in section of coating according to results of aerial photo coverage using UAV in presence and absence of snow cover. Value ρ_s is determined from known physical models depending on air temperature and average value of calculated snow load is determined in coating area P_s. Obtained value is compared with the design limit value of the snow load in the coating area P_{s ult} determined in accordance with the requirements of the valid normative documents, if condition 0.9 P_{s ult} ≤ P_s ≤ P_{s ult} is met in the corresponding section of the coating, the state preceding the moment occurrence of excessive snow load.

EFFECT: technical result is enabling improvement of accuracy of remote determination of snow cover parameters.
