Abstract

The invention provides a super-high / ultra-high voltage power transmission line radar remote sensing monitoring method. A monitoring system employed by the method comprises the following three units: a data preprocessing unit, a lead and iron tower object characteristic detection unit and a line safety state assessment unit. Data acquired by a high resolution SAR (Synthetic Aperture Radar) satellite goes through the data preprocessing unit, the lead and iron tower object characteristic detection unit and the line safety state assessment unit in order, thus line safety state assessment information is generated. According to the invention, by utilizing all-weather and all-time information expression force of high resolution SAR satellite remote sensing data in wide area space, and specific reflection characteristics of a power transmission line and an iron tower in the high resolution SAR data, safety state of the power transmission line is monitored. Through fusion processing on lead and iron tower reflection speckle information and object characteristic detection data, line safety state assessment data is generated, and a scientific basis for electrical network power transmission line safety state early warning and disaster assessment is provided.

Description

technical field [0001] The invention relates to the field of super / ultra-high voltage transmission line monitoring, in particular to a radar remote sensing monitoring method for super / ultra-high voltage transmission lines, in particular to a method for monitoring the safety status of super / ultra-high voltage transmission lines using high-resolution SAR satellite remote sensing technology. Background technique [0002] my country's transmission lines cover a wide area, the line transmission distance is long, and the terrain is complex and the climate is changeable. The climate change and natural disasters in any area will threaten the safe and stable operation of the transmission line, and even cause large-scale power grids. Range power outages. As one of the most important infrastructures in the national economy, the operation status of transmission lines and towers determines the stability and security of the entire power grid. Therefore, monitoring the safety status of pow...
