Diver-NETZ - Mobile Diver- Gate(M) Smartphon e Bluetooth < 500 m GPRS Diver- DXT fileserver
Diver-NETZ - Telemtry Diver-Gate (S) GPRS Avocet-Hydro Diver-DXT
Components Diver-NETZ Diver-DXT (with cable and Diver): Short range radio (500 m LOS) Build-in baro data logger Battery life >5 years Diver-Gate(S) for fixed setup: Short range radio GPRS (Europe/us) External power supply Battery life >2 year (10Ah) Diver-Gate(M) for mobile use: Short range radio Bluetooth interface to pc Internal antennas Diver-Mobile: Rechargeable battery For windows Mobile Automatic data read Send data to ftp-server Other tools: Avocet-Hydro Labview tools
Workflow Diver-NETZ (Diver- Gate(S)) Diver-Gate(S) periodically wakes up (example: ones a day, user setting). Diver-Gate(S) scans for Diver-DXTs (takes 30sec). Diver-Gate(S) collects data from all Divers and Baros (last or All data, user setting). Diver-Gate(S) created one file ( *.dxt-file) and sends it to ftp-server. Diver-Gate(S) created a house keeping file ( *.log-file) and sends it to ftpserver. Diver-Gate(S) goes back in standby mode. Files are collected by Avocet-Hydro
Reasonable cost satellite data workflow modem provider receiver Example: Diver-Gate will be plugged to a Satellite modem like LeoCell Field Diver data will transit to a Satellite owned by Orbcomm, GlobalStar, Inmarsat Diver Data from the Satellite will be then sent periodically to the Satellite provider data center in Canada, US, UK Lastly, the Data Center will send Diver Data to end client by e-mail or to a server
Data management How do we manage the data?
Watercompany Vitens - Hollande 1,6 Million d abonnes 4,0 Million de personnes 270 Million m³ annuels 65 station de pompage 1200 puits de production 4500 puits d observation Obligés de prendre des mesures Tous les 14 jours/ 24 mesures par an Mesures manuelles Données exportées sur la base de donnée nationale
Radio Range to Diver-DXT Street pot: Diver-DXT is under ground level. Radio distance LOS 100m. Radio distance around corner 20m. Metal cover: Diver-DXT is 1m above ground level. Radio distance LOS 200m. Plastic cover: Diver-DXT is 1m above ground level but with vegetation. Radio distance LOS 200m.
Watercompany Vitens Today, 4500 Divers are used to monitor groundwater level On-Time data Delivery Solutions enabling customers to translate acquired data into useful information GIS Vizualisation QA/QC data Automatic reporting Data transfer to national database
