METHOD MONITORING COMPLIANCE WITH ROAD TRAFFIC RULES Russian patent published in 2012 - IPC G08G1/01 

FIELD: physics.

SUBSTANCE: system has a signalling device (1) placed on a control point and an actuating device mounted on a vehicle. The signalling device (1) has a discrete signal input unit (2), a synchroniser (3), a transmitting device (4), a pseudorandom code generator (5), a first heterodyne frequency synthesiser (6), power amplifiers (7) and (23), a phase-shift keying device (8), mixers (9) and (25), a carrier frequency synthesiser (18), a first intermediate frequency amplifier (19), a duplexer (20), an external antenna (21), a receiving device (22), a second heterodyne frequency synthesiser (24), a second intermediate frequency amplifier (26), a band-pass filter (28), a multiplier (27), a phase detector (29) and a recording unit (30). The synthesiser (3), pseudorandom code generator (5), carrier frequency synthesiser (18), phase-shift keying device (8), mixer (9), first heterodyne frequency synthesiser (6), first intermediate frequency amplifier (19) and power amplifier form the transmitting device. The actuating device has an analogue and discrete signal input unit, a relay output unit, a liquid crystal monitor, a controller, an external memory unit, a transceiver, a synchroniser, a pseudorandom code generator, a carrier frequency synthesiser, a phase-shift keying device (34), a first heterodyne frequency synthesiser, two mixers, a first intermediate frequency amplifier, two power amplifiers, a duplexer, a built-in antenna, a second heterodyne frequency synthesiser, a second intermediate frequency amplifier, a multiplier, a band-pass filter and a phase detector. Said system realises duplex radio communication using phase-shift keyed composite signals with pseudorandom operating frequency tuning.

EFFECT: broader functional capabilities of system through onsite detection of vehicles violating traffic rules.
