|Title:||SYSTEM FOR PRECISION MEASUREMENT OF STRUCTURE AND METHOD THEREFOR|
Disclosed are a system for precision measurement of a structure and a method therefor. A reference measuring instrument installed at a fixed location provides GPS reference information. A plurality of response measuring instruments, installed respectively at a plurality of positions on the structure, acquire acceleration information through acceleration sensors. The plurality of response measuring instruments measure a plurality of RTK displacement information by using the GPS reference information, respectively. The plurality of response measuring instruments generate and transmit the acceleration information and the plurality of RTK displacement information as one packet by time-synchronizing the acceleration information and the plurality of RTK displacement information. An operation processor receives the transmitted acceleration information and the transmitted plurality of RTK displacement information to calculate structure response information. It is possible to precisely measure dynamic behavior of structures including high-rise buildings, bridges, dams, harbors, etc. by using GPS and accelerometers.
