PDR - CONVOYS DYNAMIC WEIGHING<\/h2><\/div><\/div>[vc_column_text]\"\"<\/p>\n

The PDR<\/strong> is a system for measuring the weight per axle of the transversal and longitudinal imbalances of the trains in transit on the rail. The PDR<\/strong> was entirely designed, developed and manufactured by Siem S.r.l..<\/p>\n

The main functions of the PDR<\/strong> are:<\/p>\n

    \n
  • measurement of the axial load Q(t) transmitted by the wheel to the sleepers (for axle and right\/left wheel);<\/li>\n
  • calculation of the average transit speed of the convoy;<\/li>\n
  • detection of the number of axles of the train;<\/li>\n
  • determination of the direction of travel of the convoy;<\/li>\n
  • determination of the weight per wheel, per axle, per wagon;<\/li>\n
  • determination of longitudinal and transversal imbalances;<\/li>\n
  • recognition and description of the convoys.<\/li>\n<\/ul>\n

    The data relating to each train is acquired in real time and subsequently processed locally by the data acquisition unit; the result of the processing is then stored in a local backup archive and sent to a data collection center which displays the values of interest and any alarms.<\/p>\n

    The experimentation was carried out with a prototype installed at the Lesina station (FG) from 2005 to 2007.<\/p>\n

    \n
    \n

    The activities involved the design, prototype construction and execution of functional tests on a section of the railway line.<\/p>\n
