Data collection framework for Research & Science

The Alfred Wegener Institute (AWI) is a pioneer in digitalisation of research data acquisition processes. They use a FIELAX data collection framework to automatically collect data from various research platforms worldwide such as drift buoys in the Arctic, satellite base stations or moving vessels. The framework continuously collects so called “near real time” (NRT) data via protocols like FTP, SMB or IMAP. Regular expressions and filters help to specify only a subset of data files / emails to be downloaded. Post-processing scripts can be automatically triggered after a successful download.
The framework is currently installed at AWI and on AWI’s research icebreaker RV “Polarstern” helping out there to acquire e. g. satellite-based ice concentration or meteorology maps.

RDI ADCP data averaging and conversion tool

FIELAX developed a software tool called “ADCP-to-DSHIP” that continuously acquires data from a ship-board RDI ADCP and calculates average values to be sended over e. g. to a data acquisition system.
The software has been installed on RV “Polarstern” on behalf of Reederei F. Laeisz GmbH. It acquires binary ENX data from an RDI OceanSurveyor ADCP from VMDAS via network and outputs NMEA-like average values to the connected ship’s central data acquisition system WERUM DSHIP.

Web portal

For the Alfred-Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung we developed a web-based platform for a unified naming of scientific device types used on German research vessels. Device types may be added and updated, may be reviewed and applied by curators and finally downloaded as XML lists from the research vessels themselves for speaking a unique “language”. The project was implemented with the PHP Symfony framework and MySQL database.

Anode mass calculator for Weserwind

By order of WeserWind GmbH Offshore Construction Georgsmarienhütte we developed a web-based intranet application to calculate anode masses for offshore constructions. Sacrificial anodes are used to protect offshore steel constructions from corrosion. Our application calculated the required amount of anode masses to protect a given metal area with given coating for a given lifetime on basis of several corrosion protection norms.
