RAILPROF MEASUREMENT OF RAIL WELDS AND CORRUGATION New software release for RAILPROF PDA Version 4.1 of the RAILPROF PDA software has been released. This version contains a built-in ftp client for wireless transfer of measurement files to a central PC. Desktop software modified for assessment of grinding work according to German standards |
||||
A new version of the
RAILPROF PDA software is released with the following new features:
built-in ftp client for wireless transfer of measurement files. The
files are stored on the ftp server in the directory \\Job\Welder. At
any time the welder can push the button Send FTP to send all the
measuring files not yet transmitted. A copy of the files remains on
the SD card of the PDA. Furthermore additional speed classes have
been added, especially in the lower speed range for metro and tram
applications. The third point is that the RAILPROF will be kept
awake as long as the operator is working in the measuring menu on
the PDA. Normally the RAILPROF is switches off after 10 minutes of
not being used. |

|
We also offer a ruggedized Symbol MC70 PDA with industrial specifications
and GPRS. MC35 with built-in GPS
|
 RAILPROF is controlled by a Pocket PC (PDA). Vertical and lateral geometry are measured simultaneously. The measuring results are automatically sent to the PDA, which carries out all the calculations like filtering and computing the first derivative of the vertical geometry. This is in accordance with the new force-based weld standards of ProRail, the Dutch Rail Infra Manager. RAILPROF is a tool for accurately measuring longitudinal rail geometry. Low weight (6 kg for RAILPROF 1000) and robustness could be realized through the use of high tech materials developed in space technology. Background information on new rail geometry standards

| Recently weld registration software has been developed by which also RAILPROF measurement files can be transferred wirelessly via GPRS. For details click here. | ||||

Some PDA screen shots Templates can be created for each measuring job via the 'Setup' menu. The values of the active template are used when the measuring process is started. After tapping the command measure the values of the template are shown and can be altered. If the weld is measured again or a new weld is measured the previous values are kept. |

| For Glued Insulated Joints (GIJ) a special feature is available to clip out the part between the rail ends at the joint. The eddy current transducer sees this area as a large deviation. When the correction is set to 'Yes', the central 10 mm of the measurement is removed and replaced by values linearly interpolated between the measured values at both ends. | ||||

The desktop software now offers the possibility to select records on the basis of the quality index QI. Via the find icon a screen is opened in which a choice can be made for QI Top, QI Hor, or both. The selection value is default 1.00, but the user can assign any other value. After OK the screen at the bottom left shows just the selected records, which can be moved now.
