GPS를 이용한 대형구조물의 실시간 경보 시스템

Real Time Alarm System of Enormous Structure Using GPS

Such social structures as bridges, buildings, dams and towers have been transformed by their own load or fundamental ground They have been behaved by other external causes. These regular or Irregular behaviors threaten to do their users safety Therefore, to monitor the load of the structures or reaction shown by them could help to verify their behaviors. RTK GPS allows the use of a static base station and remote rover unit to allow for data collection witbin several seconds and in real time. It is useful for monitoring the behaviors of massive structures like bridges. In this Study, Among GPS methods, we used RTK GPS to analyze the precision of mortitoring and then on the basis of it, we developed a mortitoring system using RTK GPS when measured the behavior of main tower of a suspension bridge by using RTK GPS Comparing a deviation between observation values, X axis was Imm, Y axis was Imm and Z axis 2.2mm. It turned out that it was possible to monitor and measure structures by RTK GPS.
