PURPOSE: A system for sensing a deformation of gas facilities using a GPS(Global Positioning System) is provided to measure/sense a three-dimensional transformation of gas facilities including a gas piping by processing carrier wave observation data of a GPS. CONSTITUTION: A GPS satellite group(110) turns round the globe and transmits an electric wave signal. A GPS observation unit(120) is mounted in gas facilities and a gas structure and senses a three-dimensional variation and movement. A sensing center server(130) receives GPS carrier wave observation data observed through the GPS observation unit(120), GPS carrier wave observation data of a nation GPS standard network(200), and an orbit power being supplied from a GPS observation network, and controls the GPS observation unit(120) in a remote place. A data collection DB server(140) stores the GPS carrier wave observation data observed through the GPS observation unit(120), the GPS carrier wave observation data of the nation GPS standard network(200), and the orbit power being supplied from a GPS observation network. A data processing server(150) calculates a variation in accordance with transformations of the gas facilities and the gas structure based on the stored GPS carrier wave observation data and the orbit power. A sensing state display unit(160) displays the calculated variation. A wire/wireless communication network(170) connects the GPS observation unit(120) to the sensing center server(130), and nation GPS standard network(200) to the sensing center server(130), receives the observed GPS carrier wave observation data, and transmits a remote control signal. An Internet network(180) connects an international GPS observation network(300) to the sensing center server(130) and receives the orbit power being supplied from the international GPS observation network(300). |
