SYSTEM OF VIDEO SURVEILLANCE OVER DANGEROUS SECTION OF MAIN PIPELINE Russian patent published in 2008 - IPC F17D5/00 F16L55/26 G01M3/00 

FIELD: technological processes; physics.

SUBSTANCE: system of video surveillance over dangerous section of main pipeline, which contains video camera with unit of information lighting, sensor of acoustic emission, which is installed on gas line, multiplexer, analog-to-digital converter, microprocessor and radio-modem with radio-transmitting antenna, at that output of acoustic emission sensor is connected to multiplexer input, the output of which via analog-digital converter is connected to input of microprocessor, which is connected with its outputs to control inputs of multiplexer and radio-modem, contains three additional video cameras with units of infrared lighting and pressure detector with distributed parameters, which is installed at the boundary of monitored dangerous section of main gas line, the electrical output of which is connected to starting inputs of video cameras, the sighting fields of which cross in controlled section of main gas line.

EFFECT: increase of volume of visual information on condition of dangerous section of main gas line.
