공간정보 기반의 GNSS 와 USN 에 의한 철도구조물 미세변위 모니터링

Rail and nationally to the aging of the various structures accordingly with respect to high speed national rail network that is distributed to thousands Km"s happening largely a problem of the collapse and demolition level each year and requires a rational management techniques to solve them. Always observable is effective against a variety of positioning analysis of mm unit for the facility main parts required for a permanent precision fine displacement of the main facilities in conjunction with the real time information of the USN environment sensor, and to utilize this as a precision micro positioning information the administration was to enable a. In this study, For this installation the receiving system is relatively accessible to enable easy GNSS base line positioning to the target bridge facilities and the embankment, and this by transmits the received data in real time using the wireless WiFi daily hourly bag bridges and related facilities by automatically processing a fine position displacement of GNSS based on USN and integrated management of spatial information it was confirmed plans for a new micro-displacement monitoring and pre-disaster management of railway facilities.
