COMPUTER SYSTEM FOR CONTROLLING PORT CONTAINER TERMINAL Russian patent published in 2011 - IPC G08G1/123 G01S1/02 G01S5/02 G01S13/75 

FIELD: information technology.

SUBSTANCE: computer system for controlling a port container terminal has a dispatch geodetic point fitted with a GPS signal receiver with an antenna, a transmitting radio station and a two-way transceiver, loaders and trailers, each fitted with a two-way transceiver, a first receiver with an antenna for obtaining differential corrections from the dispatch geodetic point, a second receiver with an antenna for receiving the navigation GPS signal. There is paging and two-way radio communication between the geodetic point and each loader and trailer. Each loader and trailer are fitted with six and seven power amplifiers, a third two-way transceiver, a third transceiving antenna, fourth phase detector, a threshold unit, light and sound beacons, a second recording unit, a switch and a second delay line. Each container is fitted with a radiofrequency label in form of a piezoelectric crystal on whose surface there is an aluminium thin-film interdigital transducer of surface acoustic waves and a set of reflectors. The interdigital transducer consists of two comb-type systems of electrodes deposited on the surface of the piezoelectric crystal.

EFFECT: high efficiency and broader functionalities of controlling a port container terminal.
