The invention discloses a
laser power automatic adjusting method and
system in a remote
foreign matter removing process of a
power transmission line, and the method comprises the steps: recognizing and positioning a
foreign matter through an inspection image, analyzing the spatial position relation between the
foreign matter and a
power transmission line, preliminarily judging the contact state of the foreign matter, and outputting a contact
risk level; analyzing the foreign matter, and constructing an initial
thermal coupling risk parameter based on the contact
risk level; controlling the
laser to perform short-time
irradiation on the foreign matter for a preset time length at the tentative power, and synchronously collecting thermal response characteristic information generated by the surface of the foreign matter in the
irradiation process; based on the thermal response feature information, comparing with a preset thermal response
reference model, dynamically judging the actual
thermal coupling state between the foreign matter and the
power transmission conductor, and correcting the initial
thermal coupling risk parameter in real time according to a judgment result to obtain a corrected thermal
coupling risk parameter; and according to the corrected thermal
coupling risk parameter, gradually increasing the
laser power of the laser to an effective clearing power interval so as to complete foreign matter clearing.
