Abstract

The invention discloses a power transmission tower deformation monitoring method based on Beidou III double-frequency non-combined RTK positioning. The method comprises the following steps: 1, a monitoring point receives a Beidou III satellite signal, and performs demodulation, despreading, decoding and resolving to obtain a pseudo-range and a carrier phase observation quantity; 2, a reference station receives the Beidou III satellite signal, performs demodulation, despreading, decoding and resolving to obtain the pseudo-range and the carrier phase observation quantity, performs positioning, and obtains differential correction data through an algorithm; 3, the reference station and the monitoring point perform differential positioning through a differential positioning algorithm; 4, deformation displacement data is transmitted to a server through a communication network, and a server calculates an offset according to change of a real-time positioning point; 5, offset data is recoded toa data center, and an early warning is given according to a preset safety threshold; and 6, user windows and an android client access the server to obtain historical change data and view real-time deformation data.

Description

technical field [0001] The invention relates to a differential positioning algorithm using the new system signal of the Beidou-3 satellite navigation system, in particular to a deformation monitoring method for transmission poles and towers based on the Beidou-3 dual-frequency non-combined RTK positioning. Background technique [0002] The power system is mainly composed of power generation, power transformation, power transmission, power distribution and dispatching. The transmission line tower is an important part of the power system, and it is proposed along with the intelligent power transmission in the smart grid. It is very necessary to monitor the deformation of important transmission line node poles and towers. The distribution area of ​​transmission poles and towers is wide, and the risk management of towers is becoming more and more important. The main reasons for tower deformation are as follows: [0003] 1. External force damage affects the deformation of the t...
