Monitoring method and system for hidden dangers of geological subsidence of power grid tower equipment based on SAR satellite data

Abstract

The invention discloses a monitoring method and system for hidden dangers of geological subsidence of power grid tower equipment based on SAR satellite data, which relies on SAR satellites to carry out wide-area geological subsidence monitoring on target areas, and analyzes and processes the monitoring results through a data processing module to obtain the target The long-term and slow geological subsidence in the region is superimposed on the GIS geographic information system of the power grid, and the information is automatically pushed according to the subsidence, voltage level and importance of the power grid tower equipment. The equipment operation and maintenance unit will feed back the site survey results to the system for continuous optimization The satellite image processing model and algorithm finally realize the visualization of the geological subsidence distribution of the power grid. The invention greatly reduces the workload of manual on-site measurement, shortens the acquisition period of geological subsidence results of the power grid, and realizes long-term, high-precision, large-scale and objective geological subsidence results of power transmission and distribution equipment in the power grid. The distribution and its occurrence trend provide support.

Problems solved by technology

[0002] Geological subsidence is a slow-changing, long-term accumulation process, and long-term effective geological subsidence monitoring must be carried out. However, although the current traditional geological subsidence methods have high precision, they only monitor the results of discrete points or lines, and cannot monitor large-scale geological subsidence. Effective monitoring of uneven geological subsidence

[0003] The power transmission and distribution equipment of my country's power grid covers a wide area, and the geological conditions along the way are complex. At the same time, affected by traffic, terrain and other conditions, it is difficult for operation and maintenance personnel to carry out full coverage, high-frequency and high-efficiency monitoring of equipment within their jurisdiction

If there is no effective monitoring of geological subsidence for a long time, it will be difficult to accurately grasp the geological disaster risk status of the power grid tower equipment. In severe cases, the tower will be tilted or even the tower will be broken, which will endanger the safe and stable operation of the power grid system.
