Abstract

The invention discloses a remote-sensing-technology-based vegetation danger early warning system and method of transmission line. The system includes a vegetation growth prediction module, a vegetation height extraction module, a power line elevation extraction module, a relative distance calculation module, and a vegetation risk early warning module. According to the invention, the safe distanceassessment of the vegetation risk section can be realized by combining the spaceborne remote sensing technology with the airborne remote sensing technology; and plants growing too high are felled timely. A reasonable inspection plan can be formulated to reduce the number of manual inspection, so that the safety of transmission lines is ensured and the consumption of human and material resources isreduced.

Description

technical field [0001] The invention relates to the field of early warning of vegetation danger of transmission lines, in particular to a system and method for early warning of vegetation danger of transmission lines based on remote sensing technology. Background technique [0002] In recent years, with the construction of UHV transmission lines, the power grid has developed rapidly, and my country has basically formed a complete long-distance power transmission grid. Overhead transmission lines will pass through areas with dense vegetation such as mountainous areas and forests. If the vegetation grows too high, it may come into contact with the transmission line, causing the line to trip and cause a power outage. In order to maintain the safe and stable operation of the power grid, regular inspections of transmission lines are required, and threatening vegetation should be pruned in time. At present, vegetation growth information on transmission lines is mainly obtained by...
