LINEAR MANAGEMENT SYSTEM OF A GRAND BRIDGE, CAPABLE OF MANAGING THE LINEAR MANAGEMENT OF A GRAND BRIDGE BY ACCURATELY MEASURING COORDINATES

摘要

PURPOSE: A linear management system of a grand bridge is provided to calculate the corrected value of a cable tension by calculating the degree leaved from the target.;CONSTITUTION: A linear management system of a grand bridge comprises a main tower position information collector(100) and a linear management unit(300). The main tower position information collector is installed at the upper part of the main tower of a grand bridge. The main tower position information collector receives the location coordinates data of the main tower from the GPS satellites. The linear management unit is installed at the reference point. The linear management unit receives the location coordinates data of the reference point from the GPS satellites. The linear management unit compares the location coordinates data of the reference point to obtain the measurement error. The linear management system calculates the corrected value of the cable tension of a grand bridge.;COPYRIGHT KIPO 2010
