Technique on the Disaster Protection Monitoring of Construction Sites based on Spatial Information and GNSS/USN/loT

摘要

The monitoring technique by combination of the measurement method and the fine precision of the sensor collecting the satellite-based information that can determine the displacement space is available in a variety of diagnostic information and the GNSS by first sensor it is being requested from them. Be large and that the facility is operated nationally distributed torsional displacement of the terrain and facilities caused by such natural disasters progress of various environmental factors and the surroundings. To diagnose this spatial information, which contains the various sensors and instruments tracks the precise fine displacement of the main facilities and the first reference in the Geospatial or more three-dimensional detailed available map and location information using the installed or the like bridges and tunnels produced to a USN/IoT change at any time, each sensor installed on the facility is to collect and integrate it precise positioning and environmental factors. In other words, by combining the various positioning analysis of mm-class for the facility main area observed is required to constantly in the real time information of the USN/IoT environment sensor, and to utilize this as a precise fine positioning information to the precise fine displacement of the semi-permanent main facilities It managed to be efficient against. In this study for this installation the receiving system is relatively accessible to enable easy USN/IoT base line positioning to the target bridges, and this by transmits the received data in real time using the wireless WiFi/Bluetooth daily hourly bag bridges and related facilities and to automatically process a fine position displacement. Analyzing the results presented to a method capable of real-time monitoring for a large structure or facility to disaster prevention.
