Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Visible light refers to the part of the electromagnetic wave that can be discerned by the human eye. In a brightly lit environment, a visible light camera can filter out excess stray light interference and obtain a good image effect. Accordingly, the present invention proposes a laser deicing device based on vision, which can obtain the ice information of the line in a bright environment, and can effectively improve the accuracy of the laser deicing device during the operation of the target according to the characteristics of the ice and snow covered cables. The recognition rate is high, and the target can be tracked accurately even when the target is shaking, so that the laser can be aimed at the ice and the efficiency of the laser operation is improved.

Abstract

The invention discloses a laser ice-removing device based on vision. The laser ice-removing device comprises a rotating table, a laser part, a base, a power supply system, an input and output device,a control system and a vision sensor module. The visual sensor module comprises a visible light camera. The rotating table comprises an orientation part and a pitching part. The orientation part is mounted above the base. The pitching part is mounted above the orientation part. The laser part and the vision sensor module are mounted on the pitching part. The control system is connected with the rotating table, the vision sensor module and the laser part, drives the rotating table and then drives the vision sensor module and the laser part to complete icing tracking and removing. The laser ice-removing device has the characteristics of being capable of realizing hot-line work and high in automation level, accurate tracking can also be achieved during target shaking, and thus lasers can aimat ice cubes.

Description

technical field [0001] The invention relates to the field of deicing of high-voltage transmission lines in power systems, in particular to a vision-based laser deicing device. Background technique [0002] In severe cold, rainy and snowy weather in winter, transmission lines and towers are likely to be covered with ice and snow. In severe cases, it may cause cable breakage and tower collapse, resulting in casualties of people and animals around, damage to transmission lines, and great losses. Overhead transmission lines have the characteristics of multiple points, wide areas, large spans, and long lines. Deicing of transmission lines is very difficult. [0003] Existing methods for removing ice and snow from high-voltage transmission lines mainly include four types: mechanical deicing, thermal ice melting, natural deicing (also called passive deicing), and mixed methods. Mechanical deicing is a kind of contact deicing operation, which has poor safety performance, requires p...
