Abstract

The embodiment of the invention discloses a laser ice melting system and method. The system is characterized in that an ice monitoring device disposed at an overhead cable is charged by a laser; whena charging time reaches a predetermined time or a charging power quantity reaches a predetermined ratio, initiating the ice monitoring device to perform real-time monitoring on the thickness of the ice covering the overhead cable; modeling the overhead cable to obtain a cable modeling model, determining the shape, trajectory, endpoint position and / or distance of the overhead cable; illuminating the overhead cable with the laser to melt the ice covering the overhead cable according to a real-time monitoring result and the modeling model, and when the ice thickness of a current melting point isbelow a first threshold, controlling a light spot of the laser to move along the overhead cable to a next melting point until the melting of ice ends. Through such an ice melting operation, the ice melting efficiency can be improved, and the labor cost can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to the application field of optoelectronic technology, and in particular to a laser ice melting system and method. Background technique [0002] With the continuous deepening of the grid marketization process and the continuous improvement of users' requirements for power reliability and quality, the power industry is facing unprecedented challenges and opportunities. Building a controllable, safe, reliable, environmentally friendly and economical smart grid system is becoming a A common goal for the global power industry. [0003] At the same time, the current removal of icing on overhead transmission lines mostly relies on high-current melting ice, but this method cannot achieve the removal of icing on overhead wires, and an effective overhead ground wire melting technology is urgently needed. Contents of the invention [0004] In view of this, embodiments of the present invention provide a laser deicing...
