Wireless sensor network based ground displacement data transmission technology in tunnel

Wireless sensor network based ground displacement data transmission technology in tunnel


  • Ground displacement data analysis system provides measurements of accurate changes such as ground pressure, load, stress, and aging based on displacement sensor. Real time gathering of sensing information using ubiquitous sensor network technology to analyze and manage ground displacement.
  • Transmit ground displacement data to long-distance area (more than 1km) using 900MHz band wireless sensor network in tunnel.
  • Use unlicensed frequency 900MHz band (902MHz ~ 928MHz) for outdoor longdistance transmission.
