Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] It should be noted that, in this embodiment, in order to distinguish it from the background color of ice, the laser emitter here irradiates the overhead transmission line with a red beam. Those skilled in the art should understand that in other embodiments, other It is also achievable to irradiate the overhead transmission line with color, and details will not be repeated here.

[0044] see figure 1 , figure 1 It is a flow chart of the method for monitoring the ice thickness of overhead transmission lines based on laser coloring in the present invention, such as figure 1 As shown, the met...

Abstract

The invention discloses a method and system for monitoring the icing thickness of an overhead power transmission line based on laser coloring. The method comprises the following steps of: A, receiving a monitoring command of the icing thickness of the overhead power transmission line or setting the monitoring arrival time of the icing thickness of the overhead power transmission line; B, coloring the overhead power transmission line according to the monitoring command or the monitoring arrival time; and C, acquiring a clear outline of the overhead power transmission line by shooting the colored overhead power transmission line, and calculating the icing thickness value of the overhead power transmission line by refereeing to the outline of a non-iced overhead power transmission line. Due to the adoption of the technical scheme, accurate monitoring of the icing thickness of the overhead power transmission line is realized, reliable data support is provided for avoidance of the icing disasters of the power transmission line for the power department, the power accident incidence rate caused by icing disasters is remarkably lowered, the running safety and reliability of a power grid and the intelligent ice disaster resisting level of the power grid are greatly increased, and huge economic benefit and social benefit are achieved.

Description

technical field [0001] The invention relates to the field of cable monitoring, in particular to a method and system for monitoring the ice thickness of overhead power transmission lines based on laser coloring. Background technique [0002] Electric power is one of the pillars of my country's economic development and the main artery for the normal operation of the national economy. The safe operation of the power industry has a direct impact on the normal operation of all walks of life. However, severe meteorological disasters, especially icing, pose a serious threat to the safe operation of overhead transmission lines, cause heavy losses to the national economy, and seriously affect the normal production of the country and the lives of the people. [0003] Around the Spring Festival in 2005, there were extremely rare freezing rain, rain and snow in central China. In particular, Hunan and Hubei provinces suffered from large-scale, long-term, and high-intensity natural disast...
