  15. BASE STATIONS & SOFTWARE • Leon County Court House • NWS Office on the Florida State University Campus

  16. XCONNECT SOFTWARE • Sutron’s 4th generation base station product • Based on open architecture: • Data storage in standard SQL database – user may choose Access, SQL Server, or Oracle • Easy third-party software connections through standard Windows COM and DDE interfaces • Reports developed through inexpensive third-party tools instead of proprietary software (Crystal Reports) • Communications protocol based on ISO layered model that forms the basis of TCP/IP • Web posting through standard features off database

  17. XCONNECT SOFTWARE Can run anywhere on the network (standard real-time trending client)

  18. XCONNECT Crystal Reports Viewer & Standard Report Set

  19. XCONNECT Easy Set-Up Windows

  20. XConnect Web Reports is an Internet Information Server (IIS) web application • Uses server-side Active Server Page (ASP) to: • Accept the user input within browsers • Retrieve the data from database • Format it into Extensible Markup Language (XML) • Extensible Stylesheet Language Transformations (XSLT) to format the data into viewable web pages

  21. MAINTENANCE & SUPPORT MOST IMPORTANT ASPECT OF ENTIRE SYSTEM

  22. SUTRON IN PUERTO RICO The Automated Dam Data Acquisition & Alarm Reporting System (ADDAARS) 25 SatLink2 GOES Satellite Transmitter/Loggers 15 Bubbler Water Level Sensors 5 XLite Data loggers XConnect Open Database Software Sutron GOES Satellite Receiver Station Sutron Engineering Services Project Value to date: $299,560 Repeater Station USGS Photo of Sutron's XLite

  23. Automated Dam Data Acquisition & Alarm Reporting System in Puerto Rico (ADDAARS) • In Puerto Rico, a small Caribbean island, the runoff its on average of 70 inches of rain per year is distributed along the northern and southern coastal plains and stored in 36 reservoirs.

  24. Background... • These reservoirs are mostly for irrigation, hydroelectric and domestic purposes, and are concentrated in the south-central region. • Most are located at distant and difficult-to-access sites in regions of varied terrain, which make them hard to monitor. • The majority of the dams were designed and built prior to the 1950’s when the population was about 2.2 million. Since then, the population has almost doubled, resulting in a boom in housing construction, in many cases just below most reservoirs

  26. Field Station with Antenna & Solar Panel SCOPE • As a result, along with several other factors such as new design parameters, topography, geology, regional seismicity and age of dams, these dams are now classified as high-hazard • The Automated Dam Data Acquisition and Alarm Reporting System (ADDAARS) was conceived and designed to obtain, monitor and analyze, in real-time, critical safety parameters such as inflows, outflows, gate openings and lake elevations for 29 principal reservoirs

  27. FLOOD SYSTEM DCP • The DCP collects, stores, and prepares data for transmission via: • Satellite • Radio • The DCP manages all scheduling of sensor readings and organization of sensor data. • Water level sensors • Radar based sensors • Submersible pressure gages • Non-submersible (bubbler) pressure gages • Pluviometers • Tipping bucket rain gages • Gate Position sensors • Shaft-encoders • Integration with existing sensors (i.e. Modbus)

  28. SATELLITE TRANSMITTER • 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. All scheduling of satellite transmissions is handled by the DCP and the satellite transmitter • 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, you rely on the DCP to provide you the data you need.

  29. NOAA / NWS GOES-8 (East) Satellite Lake Station USGS Offices in Guaynabo PREPA Offices in Santurce Database Replication Internet 3 USGS Offices with redundant Internet data: East Coast, Midwest, and West Coast Flow of Data via Satellite • Under Normal Conditions data are: • Collected and stored every 5 minutes • Data for every 15 minutes during the last 2 hours are provided to the satellite transmitter • Data are transmitted every 1 hour • Since the last 2 hours of data are transmitted every 1 hour, each transmission contains 1 hour of fully redundant data

  30. 900 MHz Spread Spectrum Radios • The radios do not require an FCC license to operate while VHF radios do require a license • The radios are subject to less interference when compared to VHF radio frequencies • They have the capability for 10/100 BaseT networking at 512 mbps • They have two network-routable serial ports

  32. HYDROLOGIC DATABASE SOFTWARE • Hydrologic database software is used to • decode satellite and radio transmissions • store the decoded values in a database • display the data in both tabular and graphical format • send alarms via beeper messages, email, fax or specialized programs • A graphical user interface (GUI) is used for quick and efficient access to data from multiple stations and sensors • The hydrologic database software provides flexible tools to review satellite and radio data either independently or together • The database software also facilitates evaluation of the condition of the station and quality of data, as well as provides a wide range of reports to present both summarized and detailed information in printed form

  35. ADVANTAGES OF A SUTRON SYSTEM • ALERT ADVANTAGES • IF the need arises – XConnect software supports a true NWS ALERT-protocol receiver as an input type • ALERT stations can be incorporated along with any other data source • Just define the station as type ALERT • MULTIPLE BACK-UP PATHS SUPPPORTED Sutron XConnect provides so many ways to get data from ONE station, all at the same time: • LOS Radio • Direct Wire • All forms of cellular telephone • Dialup telephone • GOES Satellite

  36. OPEN ARCHITECTURE • Data storage in a standard SQL-compliant relational database • Standard Windows COM and DDE interfaces for 3rd-party software compatibility (WonderWare InTouch, Other MMI packages) • Database includes all information required for GIS (properly formatted latitude, longitude, and station elevation) • Easy extension & customization • Sutron's highly versatile dataloggers can be connected to virtually any hydrologic instrument. • Custom or 3rd Party Map Displays “Hot points” to see current data

  37. Tips . Be Realistic • Designed a Network that you are able to maintain. . Do you Homework • Check out potential suppliers. • How good is their support?
