System for precision measurement of structure and method therefor

Abstract

Disclosed are a system and a method for precisely measuring a structure are disclosed. A reference meter installed at a fixed location provides GPS reference information. A plurality of response meters, respectively installed at a plurality of positions of the structure, acquire acceleration information through acceleration sensors and measure a plurality of real-time kinematic (RTK) displacement data based on the GPS reference information, respectively. The response meters synchronize acceleration information with the plurality of RTK displacement data measured to generate into a packet to be transmitted. An operation processor receives the acceleration information and the plurality of RTK displacement data and calculates structure response information. With the GPS and accelerometers, the dynamic behaviors of structures including high-rise buildings, bridges, dams, and harbors can be precisely measured.
