Description

Technical Field

[0001] This invention relates to the field of power facility technology, and in particular to the method, system, equipment and medium for arranging composite overhead ground wire optical cables. Background Technology

[0002] Optical fiber composite overhead ground wires (OPGW) are a unique technology in power systems, possessing the dual functions of power line grounding and optical fiber communication. OPGW optical cables have the dual functions of grounding and optical fiber communication in their structure, so the line design is the same as that of ordinary grounding cables. OPGW optical cables place optical fibers in an overhead ground wire, combining lightning protection and communication functions into one composite ground wire.

[0003] OPGW optical fiber cable has the dual functions of traditional overhead ground wire and optical fiber communication capability. The basic structure of OPGW consists of a cable core containing optical fibers (optical unit) and stranded metal wires (aluminum-clad steel wire ACS or aluminum alloy wire AA); among them, the optical fiber provides the transmission channel, the steel component mainly provides mechanical strength, and the aluminum component mainly carries short-circuit current.

[0004] In the relevant technical solutions, the layout of OPGW panels and down conductors uses an estimation method. When dividing the OPGW into panels, it is impossible to perform reasonable automatic panel division based on the actual terrain environment. Often, additional panel division calculations are required during implementation, which greatly reduces the effectiveness of OPGW panel division, affects the OPGW installation process, and prolongs the construction period. Furthermore, when laying down conductors for OPGW, the layout of down conductors needs to vary depending on different ground conditions. There is a significant lack of consideration for the thickness of walls and the need to resist external environmental interference. The lack of a systematic and accurate layout method results in poor performance. Summary of the Invention

Obviously, the drawings in the following description are only some embodiments of the present application, and other drawings can also be obtained by those skilled in the art without any creative labor.

[0044] Figure 1 The arrangement method of the composite overhead ground wire optical cable provided in the technical scheme of the present application is shown in the flow chart. DETAILED DESCRIPTION

[0045] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application. For the step numbers in the following embodiments, they are only set for the convenience of explanation and description, and the order between the steps is not limited in any way, and the execution order of each step in the embodiments can be adaptively adjusted according to the understanding of those skilled in the art.

[0046] The technical problem pointed out in the background art is that the traditional OPGW disc and down lead arrangement cannot reasonably and automatically disc according to the actual terrain environment when discing the specific OPGW, and additional disc calculation is often needed in specific implementation, which greatly reduces the disc effect of OPGW, affects the erection process of OPGW, and prolongs the construction period. And when the OPGW down lead is arranged, different ground conditions need different down lead arrangements, and the arrangement for passing through the wall thickness and resisting environmental interference is obviously insufficient, lacking a systematic and accurate arrangement method, and the use effect is not good. Therefore, the core idea provided by the technical scheme of the present application is to obtain the tower data and building data on the composite overhead ground wire cable erection route by using a UAV carrying a laser scanner and an image scanner, and to form a three-dimensional simulation image by using a three-dimensional GIS system. The three-dimensional modeling is used to intuitively arrange the disc and down lead of the OPGW, and the actual collected data is used to complete the automatic disc of the OPGW and the arrangement and drawing of the down lead arrangement.

[0047] In a first aspect, as shown in Figure 1 The arrangement method of the composite overhead ground wire cable provided in the technical scheme of the present application mainly includes steps S100-S500:

[0048] S100, obtaining laser point cloud data of towers and three-dimensional data of ground buildings;

[0049] In specific embodiments, a UAV carrying a laser scanner can be used to fly along the composite overhead ground wire cable erection route, record the laser point cloud data such as the distance and height of the towers along the way, and collect the three-dimensional data of the ground buildings under the towers.

[0059] In specific embodiments, the three-dimensional model is constructed by collecting data, and the actual data collected is fitted with the simulation data in the three-dimensional model. According to the fitting result, the related erection information of the composite overhead ground wire optical cable is calculated, and the composite overhead ground wire optical cable is laid according to the erection information.

[0060] In some feasible embodiments, the erection information includes the length of the composite overhead ground wire optical cable, the cable joint data, the buried wire data of the downlead, and the number of wire clamps.

[0077] The preset distance refers to the interval distance of the fixed clamp. In specific embodiments, in order to make the downlead more straight and beautiful, a fixed clamp is installed every 1.5-2 m to prevent the optical cable from rubbing against the tower.
