Electric power tower settlement monitoring method for transmitting differential data through Beidou short message

Abstract

The invention discloses a power tower settlement monitoring method for differential data transmitted by Beidou short messages, which comprises the following steps of: 1, preprocessing observation data of a base station, and calculating pseudo-range and carrier phase difference values; 2, using a grey-weighted Markov chain prediction model to compress differential data and sending the differential data through a Beidou short message; and 3, after receiving the corresponding differential data, the moving station recovers the initial data according to the same prediction model and differential strategy as the reference station, and then realizes high-precision differential positioning, thereby completing the settlement monitoring of the power tower. The method can be widely applied to tower drum settlement monitoring in a network link limited area, and has a wide application prospect.

Description

technical field [0001] The invention relates to the field of Beidou satellite navigation. Specifically, it is a power tower settlement monitoring method for Beidou short message transmission differential data. Background technique [0002] With the continuous development of the current society, energy consumption is also increasing day by day, and the development of new energy has become a current research hotspot. As an important part of wind power generation, power towers face certain risks of land subsidence due to the influence of the external environment, which will affect the safety of tower facilities and cause serious economic losses. Subsidence monitoring. [0003] Traditional total stations and levels are used for settlement monitoring, which are limited by external conditions such as artificial, weather, and environment, and are difficult to apply to large-scale scenarios. The relative positioning technology of GNSS can realize all-weather real-time monitoring,...
