Beidou navigation satellite attitude measurement-based electric iron tower deformation monitoring system and monitoring method

Abstract

The invention discloses a Beidou navigation satellite attitude measurement-based electric iron tower deformation monitoring system. The system is characterized by comprising a Beidou satellite signal receiving module, a Beidou satellite signal resolution module, a calculation processing module, a 3 / 4G wireless communication module and a power supply module. A Beidou navigation satellite attitude measurement-based electric iron tower deformation monitoring method is characterized by comprising the following steps: firstly, receiving and resolving a real-time radio frequency carrier signal of a Beidou navigation satellite; then, establishing an attitude angle mathematic model of a base line L on the iron tower; and finally solving the attitude angle mathematic model by utilizing an approximate gradient approximation algorithm to obtain the attitude angle of the base line L. The attitude angle mathematic model with multiple constraint conditions can be solved by introducing the approximate gradient approximation algorithm, has strong algorithm realizability and high attitude angle accuracy for measurement place, and has a wide application prospect.

Description

technical field [0001] The invention relates to satellite navigation technology, power system power transmission and transformation technology and intelligent information processing technology, in particular to a power tower deformation monitoring system and monitoring method based on Beidou navigation satellite attitude measurement. Background technique [0002] Most of my country's transmission lines are distributed in mountainous and hilly areas. In recent years, due to natural disasters and human factors (such as mining production, engineering construction) and other factors, accidents of power towers toppled and damaged have occurred from time to time, causing major economic losses. one of the major risks. According to DL / T 741-2010 "The Electric Power Industry Standard of the People's Republic of China: Operation Regulations for Overhead Transmission Lines", the inclination of the straight line tower: the inclination of the tower below 50m is η≤0.4%, and the inclination...
