AUTOMATIC UNMANNED DIAGNOSTIC COMPLEX Russian patent published in 2009 - IPC G01M3/00 F17D5/02 G01V3/165 

FIELD: electric engineering.

SUBSTANCE: invention relates to diagnostic devices; it can be used for systematic remote status control of gas pipe-lines and gas storage areas. Automatic unmanned diagnostic complex includes automatic control system, GPS satellites, navigation system, inertial navigation system, receiving equipment of navigation satellite system, real coordinates computer of navigation satellite system, radio beacon, system of air velocity signals, low-range radio altimeter, automatic remote control system, electronic guidance system, infological unit, receiving equipment of electronic guidance system, TV surveillance system, radiotelemetry system, system of automation onboard operation control for remotely controlled aircraft (RCA) with computer, engine control system, computer of automatic control system, radio relay, onboard system control unit, onboard information tank, landing and parachute deployment system, control unit for remote status control system of gas pipe-lines, electronic altimeter set, ground command facility, ground command console, launcher, rescue system and rudder. Radiotelemetry system contains two radio stations located at RCA and ground command facility respectively; each radio station includes high-frequency generator, source of discrete messages and commands, the first mixer, the first heterodyne oscillator, amplifier of the first intermediate frequency, the first power amplifier, duplexer, the second power amplifier, the second mixer, the second heterodyne oscillator, amplifier of the second intermediate frequency, multiplier, band-pass filter, phase detector, amplitude modulator, source of analogue messages and commands, amplitude limiter and synchronous demodulator.

EFFECT: invention is oriented to functionality extension of RCA by means of exchange of radiotelemetry and command data between RCA and ground command facility with use of discrete and analogue messages, two frequencies and composite signals with combined phase-shift keying and amplitude modulation at one carrier frequency.
