ADDAARS
provides information to decision makers
in realtime through a combination of radio
and satellite telemetry, microwave, fiber
optic and internet technology in order
to...
- Improve the distribution and use of manpower
- Provide real-time data for safe dam and reservoir operation
- Reduce emergency response time
- Provide a precise and consistent data collection system.
- Provide the tools to monitor condiitons of the dams and reservoirs in real-time at the emergency operation center and at the regional operations centers
EQUIPMENT
Data collection platforms (DCP) collect data from sensors at each site and
transmit values via satellite and radio
SENSORS
- Water level sensors
- Radar based sensors
- Submersible pressure gages
- Non-submersible
- Pluviometers
- Tipping bucket rain gages
- Position sensors
- Shaft-encoders
- Integration with exisiting sensors (i.e Modbus)
PROCESS
The DCP collects, stores, and prepares data for transmission via Satellite
and Radio. The DCP manages all scheduling of sensor readings and organization
of sensor data.
The Satellite Transmitter receives data from the DCP and transmits
it to the NOAA GOES East Satellite.
Satellite communications are one-way from
the station to the receive site.
After the DCP is programmed, nothing can be done during an event without reprogramming
the DCP. Since all transmissions are scheduled, this is a near real-time system.
During an event, the DCP will provide all the data needed.
All scheduling of satellite transmissions is handled by the DCP and
the satellite transmitter.
NORMAL CONDITIONS
Data is collected and stored every 5 minutes.
Data for every 15 minutes during the last 2 hours is provided to the satellite
transmitter.
Data is transmitted every 1 hour.
Since the last 2 hours of data is transmitted every hour, each transmission
contains 1 hour of fully redundant data.
Data is received by central servers and stored in relational database management
systems. Hydrologic database software with a graphical user interface is used
to access the data.
