ITEG Software

Since 2002 Christoph Lechleitner (formerly IBCL) and Wolfgang Glas (formerly ev-i) develop and maintain the software for the 250 control vehicles of the german electronic truck tolling enforcement unit (MOKON) as subcontractors of EFKON AG, Graz.

This project initialized the long-standing partnership which finally amounted in the founding of ITEG IT-Engineers GmbH in July 2011.

The MOKON software package is comprised of a central GUI application which asynchrounously interfaces several systems:

  • Thales mobile payment terminal
  • DSRC transceivers
  • Backoffice communication over GPRS/UMTS, encrypted with SmartCards
  • TLS encrypted connection to external control systems over WLAN

In the course of this project we mastered the challenge to fulfill the high demands of both the infrastructure industry and the strict security regulations of the state authorities.

Development of the TIS Dam Information System of Vorarlberger Illwerke AG was started in 2010 by ev-i Informationstechnologie GmbH and KISTERS AG. This was the stepping stone for the ongoing cooperation between KISTERS and ITEG, and the starting point for the development of our visualization product TISGraph. The project was successfully completed in 2011.

TIS utilizes the constant stream of structural measurment data from sensors embedded in the dams in combination with models derived from statistical analysis of historical data to predict the deformation of the dam structure depending on factors like the outside temperature and water storage level. In the course of this project, a number of new deformation models where developed for the large dams of Illwerke AG.

We also implemented a software service for transferring the resulting threshold values to the Illwerke Control Center (ICC). As the threshold values represent data viewed as critical to plant security, the transmission and storage of these values takes place within a physically seperated control network. Due to the security constraints, the transfer service has to guarantee high availability and provide extensive monitoring facilities.

We achieved these goals by setting up the following software components:

  • highly available deployment of Kisters’ TSM-Server
  • Kisters Import-Server KiDbUtil
  • Oracle Transfer-Database FWDB
  • prediction web application and a server side scheduler for threshold values
  • Surveillance of all participating system with NagIOS

As part of a contract with Siemens AG Germany we implemented several extension modules for the existing software package “FatAss”, a toolset for fatigue assessment of steel and aluminum components.

The extension modules implement German state-of-the-art fatigue norms DVS 1608 and DVS 1612 complemented by a comprehensive test suite of both unit tests and real world examples.

The project also included the development of geometry and stress interface modules for the commercial FEM programs Ansys, Abaqus und HyperWorks. Compared to the possibilities of standard FEM programs the delivered solution offers the following key benefits:

  • Implementation of state-of-the-art norms in the field of interest
  • Assessment of stress results from several commercial FEM solvers in a central backend
  • Reduced processing time from design to fatigue assessment
  • Faster feedback cycle in the design process

The software modules are currently deployed at 3 Siemens sites in the divisions Railway Bogies and Light Trains.
