  1. Technology for Hydrologic Data Acquisition and Monitoring 2003. 8. 27 Jongkook Lee, Ph.D DataPCS, Korea

  2. Introduction • What is the technology for hydrologic data acquisition and monitoring? • Motivation (1997) • Seohae Grand bridge realtime scour monitoring • Goal • Wireless realtime hydrologic monitoring technology development for a researcher level

  3. Introduction • Other interested areas • Realtime hydrologic watershed monitoring • Realtime disaster prevention monitoring • Coastal / river / natural environment monitoring • Realtime SOC monitoring and control

  4. Feature I • What is the difference compared with the regular methods (phone to phone or dedicated wire connection) ? • Wireless Internet • Perfect glue service of PCS wireless network + High speed wired internet

  5. Feature II • Synchronized realtime data acquisition from multiple services • Old dedicated wireless telemetering (VHF) • Each node 1 sec took • 250 nodes 250 secs took ≒ 4 mins 10 secs • Wireless Internet telemetering (PCS) • Each node 5∼10 secs took • 250 nodes 5∼10 secs took

  6. Feature III • Nearly realtime services possible • Server size • Small enough fit in a desk top • Hassle-free (network service : commercial) • User only care • Remote data logging systems • A server

  7. Feature IV • It goes everywhere you want to be. • It moves anytime you want to do. • It glues anydevice you want to keep.

  8. Feature V • Remote sensing ground proof for calibration

  9. Demonstration I • Hydrologic realtime monitoring • Realtime rainfall measurement • Realtime water level measurement • Realtime water quality measurement • Realtime AWS • Realtime evaporation, soil moisture measurement • Realtime wireless watershed webcam • Wireless Internet + PDA + WEB

  10. Demonstration II • A compact wireless internet realtime datalogger • DP100 + Water level sensor (Frontier project) DP100 Water level sensor

  11. Demonstration III • Realtime coastal observation network • From Ssangjungcho light tower deck at Ullungdo • Observation station • More than 30 realtime observational parameters • Wave and Tide measurement • AWS measurement • Coastal water environmental measurement • Lantern operation measurement
