DISPATCHER SYSTEM FOR CONTROLLING AND MONITORING COLLECTOR CARS Russian patent published in 2007 - IPC G08G1/01 

FIELD: engineering of automated systems for recognition of moving vehicles, for controlling and monitoring their movement.

SUBSTANCE: system includes central dispatching station and controlling stations. Each collector car contains receiver-transmitter, receiver of GPS signals, microprocessor, control and indication panel, digital-analog converter, analog-digital converter, and speech input-output block. Each control station contains receiver-transmitter of short-rage radio-channel, microcontroller and receiver-transmitter of long-range radio-channel. Central dispatching station contains receiver-transmitter of long-range radio-channel, GPS signal receiver, micro-computer, communication channels adapter, file server, analog-digital converter, digital-analog converter, speech input-output block, automated workplaces for dispatchers and auxiliary personnel. Each transmitter-receiver includes a supporting generator, discontinuous messages source, digital scrambler, phase manipulator, time and frequency standard, two heterodynes, three mixers, first intermediate frequency amplifier, two power amplifiers, duplexer, two narrowband filters, two phase shifters, two amplifiers of second intermediate frequency, two multiplexers, amplitude detector, two keys, two spectrum width meters, comparison block, threshold block, phase detector and digital descrambler. System features suppression of false signals (interferences), received through direct passage, mirror, combination and inter-modulation channels.

EFFECT: expanded functional capabilities due to realization of exchange of confidential discontinuous information between central dispatcher station and collector cars; prevented unsanctioned access and increased precision of collector car position detection.
