Abstract

The invention discloses a method for system for monitoring multi-dimensional deformations of electric transmission lines in real time on the basis of differential positioning. According to the methodand system, a base station is electrified to carry out measurement or increase measurement frequency, longitude and latitude information of the base station is updated in real time by utilizing a known base station coordinate, and a measured carrier phase observed value, a measured pseudo-range observed value and the base station coordinate are transmitted to a background server through a 4G network in an RTCM format or a self-defined format; a monitoring station uploads acquired field state data and a command for processing a client to the background through the 4G network in the RTCM formator the self-defined format; the background server receives the information sent by the base station and the monitoring station and carries out single-system and multi-system combined calculation; andthe background server converts the three-dimensional position of the base station into a longitude, a latitude and an altitude so as to obtain the position information, relative to the base station, of the monitoring station to complete the real-time monitoring. The method and system can be used for monitoring the multi-dimensional postures of electric transmission line towers on complicated geologies so as to ensure the safe operation of the electric transmission lines.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a method and system for real-time monitoring of multi-dimensional deformation of transmission lines based on Beidou satellite differential positioning. Background technique [0002] In recent years, various geological disasters have become increasingly harmful to our country, and the losses caused by geological disasters have increased year by year. The losses caused by soil erosion, land desertification, salinization, and gleization amounted to 20 billion yuan per year, and the losses caused by karst subsidence and underground mining exceeded 500 million yuan. 46 cities in the plain area occurred, causing huge economic losses. [0003] An important reason for the occurrence of geological disasters on transmission lines is the influence of natural conditions. The specific reasons may include: First, the geological environment of the section where the transmissio...
