SYSTEM FOR REMOTE DETECTION OF DEFECTS AND PLACES OF UNAUTHORIZED PUMPING IN MAIN PIPELINES Russian patent published in 2024 - IPC F17D5/00 G01S13/88 B64U101/00 

FIELD: measurement.

SUBSTANCE: invention relates to measurement equipment and can be used for contactless control of defects of main pipelines of hydrocarbons and places of unauthorized pumping of oil using contactless aircraft. In the invention, the phased antenna array (PAA) consists of two parts of the left and right wings, the dipoles of which are connected by high-frequency cables to the adders of radio signals connected through the transmitting inputs of the circulators and the switch to the transmitter, receiving outputs of circulators are connected through switches and adder of high-frequency signals to amplitude detector, outputs of which are connected to three band-pass filters, tuned to switching frequencies, normal vibrations of the pipeline and vibration frequency of the defect, wherein switching frequency filter output is connected through phase detector to flight altitude control engine, and the outputs of the filters of normal vibrations of the left and right phased antenna arrays and vibration frequencies of the defect are connected through a microcontroller to the flash memory unit.

EFFECT: broader functional capabilities of the system in order to determine simultaneously defects, welds, line position of the pipeline and places of unauthorized pumping, increased speed of inspection, as well as reduced labour intensity.
