ITEG Software
TISGraph allows to visualize time-series data from diverse sources. TISGraph features an extensive toolset for quick and precise layouting of large amounts of data. Whether you want to informally visualize your data or need to compile reports for the authorities, TISGraph lets you simply do it.
ITEG GmbH is developing MDA (Mobile Data Aquisition), a software solution for the aquistion and management of measurement data with mobile devices. MDA currently focusses on reading data from stationary sensors in the area of water power plants and hydrology.
MDA’s components are designed for ease of operation of the mobile devices and transparent data processing.
Mesurement data are entered Offline using mobile devices with “MDA-Client for Android”, independent from any data connectivity.
Later on the data of a measurement round can be transmitted directly from the mobile device to the server in one short operation. Any available data connection can be used: WiFi, cellular radio, ethernet. No PC is required, no cable connection with USB or RS232, no proprietary PC software.
Central storage and processing of all collected measurement data is performed by a modular server software which is written in Java and can be run on any Linux or Windows system. The server software provides a web interface compatible with any modern browser with support for JavaScript.
Server users can be authenticated against your organization’s Active Directory Server and other authentication backends.
The modular architcture allows as to adapt the MDA-Server to Your needs or interconnect it with other systems.
Apart from our own software products we develop individual software according to customer requirements, mostly for infrastructure operators.
Our software supports security-relevant business-critical applications for several countries’ electronic toll collection system, allow quality management for planning big infrastructure construction projects, and several solutions for operators of dams for power production.
The focus is on:
- Scalability
- Durability
- Security
- Possibilty to monitor services

On behalf of the engineering consortium ILF/Geodata/HBI we performed a detailled fatigue analysis of the air pressure stress imposed on cross-cut doors by trains running through the Brenner Base Tunnel.
High-resolution 1D computational fluid dynamics (CFD) algorithms have been used to simulate the 24 hour air pressure load history emerging at 10 selected observation points. These results have been aggregated for the estimated 200-year life span of the tunnel using the Rainflow Method to form a resulting fatigue damage spectrum.
Furthermore, an FFT analysis has proved that no distinctive oscillation stress is to be expected from the air pressure loads.
Our consolidated findings allow BBT-SE (the key account) to reduce fatigue assessment specifications for cross-cut doors and similar construction elements, providing considerable cost savings in comparison with traditional specifications.
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.
The highy scalable toll collection front end HA-Dispatcher was developed by ev-i Informationstechnologie between 2006 and 2010. In 2011 it was taken over by ITEG.
HA-Dispatcher allows servicing of up to 20.000 simultaneously connected GSM devices for toll projects, smart grid applications or the like.
It is currently in use in the toll project Spitsmijden Brabant in the Netherlands, where 5000 OBUs are in use.
More details are available on the product website.
Lasting from Summer 2012 until early 2013, ITEG refurbished the 1D computational fluid dynamic program “Drust” for Vorarlberger Illwerke AG (VIW).
The program started as an in-house tool of VIW and uses FORTRAN-Modules written by Illwerke Engineers describing water hammers in surge chambers, turbines, pumps and pump turbines.
Based on these FORTRAN modules, VIW has been able to design some of the most innovative hydro power plants since the 1980ies, which are renowned for their utmost operational reliability.
The visualization of the calculation results involves the ITEG product TISGraph, which allows to render time dependent charts as well as parameter dependent characteristic curves.
The new version 2.0 of “Drust” allows to preserve decades of experience in a centralized database and to extend it further. Moreover, the collection of FORTRAN modules is improved in a way that allows yet another generation of highly specialized engineers to undertake state-of-the-art waterhammer simulations of new Illwerke schemes.
As a result of the successful cooperation of ITEG with the principal it was possible to implement even far reaching functionalities like rainflow-counting of fatigue damage spectrums in a user-friendly manner.
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.
