AUTOMATIC PILOTLESS DIAGNOSTIC SYSTEM Russian patent published in 2020 - IPC G01M3/00 

FIELD: diagnostic equipment.

SUBSTANCE: disclosed system relates to the field of multifunctional operation of technical diagnostic equipment and can be used for systematic remote monitoring of the state of main gas pipelines and oil pipelines, for technical survey and monitoring of areas and objects, video, photography, obtaining information on radiation of electronic means (REE), dosimetry control and other information in real time scale from the height of "bird flight" using complex equipment installed on carrier – remote-piloted aircraft (RPAC). Automatic unmanned diagnostic system comprises automatic control system 1, satellites 2.i (i = 1, 2, … 24) Navstar or GLONASS global navigation system, navigation system 3, inertial navigation system 4, Navstar or GLONASS satellite navigation system receiving equipment 5, calculator 6 of real coordinates RPAC, radio beacon 7, system 8 of air-speed signals, small radio height meter 9 of low altitude, system 10 of automatic remote control, system 11 commands of radio control, information logic unit 12, receiving equipment 13 of command radio control, overview television system 14, radio telemetry system 15, RPAC on-board systems automatic control system 16 with computer, engine control system 17, automatic control system computer 18, radio repeater 19, onboard system control unit 20, onboard information storage 21, parachute landing and release system 22, main gas line condition diagnostics system control unit 23, gas line condition diagnostics system 24, radio altimeter 25, ground control station 26, ground control panel 27, launch catapult, rescue system 28 and rudder 29. Each radio station 15.1 (15.2) contains high frequency generator 30.1 (30.2), phase manipulator 31.1 (31.2), discrete messages and commands source 32.1 (32.2), first mixer 33.1 (33.2), first heterodyne 34.1 (34.2), first intermediate frequency amplifier 35.1 (35.2), first power amplifier 36.1 (36.2), duplexer 37.1 (37.2), transceiving antenna 38.1 (38.2), second power amplifier 39.1 (39.2), second mixer 40.1 (40.2), second heterodyne 41.1 (41.2), second intermediate frequency amplifier 42.1 (42.2), multiplier 43.1 (43.2), band-pass filter 44.1 (44.2), phase detector 45.1 (45.2), oscillatory circuit 46.1 (46.2), narrow-band filter 47.1 (47.2), amplitude detector 48.1 (48.2), threshold unit 49.1 (49.2) and switch 50.1 (50.2).

EFFECT: high selectivity and noise immunity of receivers of radio stations by suppressing false signals (interference) received through mirror and combination channels.
