TaMIS
Development of a Reservoir Monitoring and Information System for Natural Hazards. BMBF research project 2015–2017, project lead Marcel Delker. Bi-directionally radio-networked sensors with a standard-compliant OGC-SOS interface, tested with the Wupperverband. The bridge project between AHEM (2009–2012) and INTENT (2022–2023).
TaMIS
An autonomous, intelligent reservoir monitoring and information system for assessing natural hazards at the dam structure.
TaMIS was a BMBF-funded project to extend the measurement and information equipment of reservoirs. The goal was a coherent, bi-directional measurement and control system: ultra-low-power radio sensors at the structure, a gateway as an internet data logger, a server backend with geo-database and validation, and an OGC-compliant SOS interface to the reservoir control centre, so that the measurement data feed straight into agency and specialist systems.
For TerraTransfer, TaMIS was the bridge between AHEM (2009–2012, hardware foundations) and INTENT (2022–2023, today's IoT probe). The first bi-directional radio loggers and the OGC-SOS interface were born here — along with several lessons that are reflected directly in today's series product: SMD-soldered flash memory instead of micro-SD (for reliability) and an integrated battery compartment instead of a removable module (for water tightness).
Reservoir structures are the application environment TaMIS was developed for.
Application and research partners
- Wupperverband Reservoir operator and research partner — the TerraTransfer measurement data are delivered to the Wupperverband's TaMIS control centre via OGC-SOS interface
- TerraTransfer GmbH Development of the bi-directional radio loggers, OGC-SOS interface and data platform
Technical building blocks
- Bi-directionally radio-networked sensors — control commands from the office desk via internet all the way down to individual radio sensors, with data harvesting through an „index" reconciliation
- Capture of seepage water level, soil moisture (tensiometers at 30 cm and 60 cm depth on upper slope, mid-slope and slope foot) and temperature
- Standard measurement interval of 15 minutes, ultra-low-power design for multi-year battery operation
- UMTS data uplink at the gateway, Linux backend with geo-database and validation
- Standard-compliant OGC-SOS (Sensor Observation Service) interface to the reservoir control centre for direct integration into agency and specialist systems
- Wi-Fi / short-range radio adapter as a commissioning and maintenance aid — Raspberry Pi prototype with mobile app, converting Wi-Fi to 433 MHz
What lives on today
The bi-directional communication tested in TaMIS, the data harvesting based on an index reconciliation and the standardised interfaces fed into our data platform and into later device generations. Marcel Delker presented the project in Dresden in 2016; the obligation to commercialise has been fulfilled since 2019 — the first adopters of the TaMIS outcomes were the Ruhrverband (new boards with improved barometric compensation) and the Office for Environment of the Canton of Thurgau (UMTS solution on the new platform). The follow-up project INTENT (2022–2023) built directly on TaMIS, and from there the current product line Aquatos Web LTX emerged.
