Technical Field

Because the wiring scheme of different sizes can be met for the ADSS optical cable wiring, and flat casting or air casting can also be met, the application is wide, if the optical cable breaks, great potential safety hazards can be brought to road traffic and power transmission lines, and the consequences such as large-area power failure can be caused when serious, so that the operation and maintenance of the ADSS optical cable at a certain frequency become important.

Generally, due to the wide use of ADSS optical cables, ADSS optical cable lines generally span a large length, and thus ADSS optical cable lines may approach different areas, for example: abnormal frequencies of ADSS optical cable lines in different areas are different in thermal power plants, forest farms, orchards, rivers and the like, for example, waste gas discharged by the thermal power plants is easy to pollute and corrode a sheath or a metal stranded wire of an optical cable, so that when the same operation and maintenance frequencies are configured for the ADSS optical cable lines in different areas, the ADSS optical cable lines cannot be attached to different area conditions in actual conditions when the same operation and maintenance frequencies are configured.

Therefore, how to perform different operation and maintenance planning for the attributes of different areas in the ADSS optical cable line is a problem to be solved.

The technical scheme of the invention is described in detail below by specific examples. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.

The invention provides a GIS-based ADSS optical cable operation and maintenance line planning method, which is shown in fig. 1 and comprises the following steps of S1-S5:

s1, determining power transmission and transformation equipment position points in a geographic information image of a target area, and connecting the power transmission and transformation equipment position points in the geographic information image according to a preset connection relation of the power transmission and transformation equipment position points to obtain a connecting line corresponding to an ADSS optical cable.

It should be noted that, the wiring scheme of the ADSS optical cable can be satisfied, and the wiring scheme of different sizes can also be satisfied, so that the application is relatively wide, and once phenomena such as optical cable fracture or corrosion occur, the mechanical, electrical and transmission characteristics of the optical cable can be caused to have negative influence, and the optical cable line and the tower can be damaged, so that large-area power failure is caused.

Therefore, the operation and maintenance of the ADSS cable in the area need to be performed at regular time, further, all the power transmission and transformation equipment position points in the geographic information image of the target area are determined, and a plurality of power transmission and transformation equipment position points are connected through a connection relation which is set in advance between the power transmission and transformation equipment position points, so that a connection line corresponding to the ADSS cable is obtained. The power transmission and transformation equipment position point can be a position point corresponding to a power transmission and transformation wire pole, and generally, a connecting line between two power transmission and transformation wire pole position points is in a straight line state.

In some embodiments, in step S1 (determining power transmission and transformation device location points in the geographic information image of the target area, connecting a plurality of power transmission and transformation device location points in the geographic information image according to a preset connection relationship of the power transmission and transformation device location points, to obtain a connection line corresponding to the ADSS optical cable), the method includes S11-S12:

S11, acquiring coordinate points of all power transmission and transformation equipment in the target area, and determining the position points of the power transmission and transformation equipment in the geographic information image of the target area according to the coordinate points.

It can be understood that coordinate points of all power transmission and transformation devices in the target area are firstly obtained, and then the position points of the power transmission and transformation devices in the geographic information image are determined according to the corresponding coordinate points of the power transmission and transformation devices. It is easy to understand that coordinate points of all power transmission and transformation devices in the area are correspondingly stored in different areas, coordinate points of all power transmission and transformation devices in the target area are obtained, and meanwhile, the geographic information image has coordinate points of all positions.

Further, the position points of the power transmission and transformation devices with the same coordinate point in the geographic information image are determined according to the coordinate points of the power transmission and transformation devices, so that all the power transmission and transformation devices in the geographic information image are determined.

S12, acquiring preset connection relations of all power transmission and transformation equipment in the target area, connecting a plurality of power transmission and transformation equipment position points with the connection relations, and taking lines among the power transmission and transformation equipment position points connected in the geographic information image as connecting lines corresponding to the ADSS optical cable.

It can be understood that after determining the position points of the power transmission and transformation equipment in the geographic information image, acquiring preset connection relations of all the power transmission and transformation equipment stored in the server in advance, and according to the connection relations between coordinate points, comparing and connecting the position points of the power transmission and transformation equipment in the geographic information image, wherein the obtained connection line between the two points is used as the connection line corresponding to the ADSS optical cable.

S2, generating a target acquisition area corresponding to the connecting line, acquiring information of a target acquisition image in the target acquisition area to obtain attribute information of the corresponding target acquisition area, and segmenting the connecting line according to the attribute information at different positions of the connecting line to obtain a plurality of first sub-connecting sections.

Since the ADSS cable has a structure in which other metal members are not required to be installed and support of other members is not required, it is possible to install a long distance, for example, 800 m, 1000 m, etc., without support of other members.

As a result, ADSS cables typically span a long distance, and in a long distance, areas of different properties, such as areas of thermal power plants, chemical plants, hillsides, rivers, forest farms, etc., are traversed, while corresponding ADSS cable segments at different areas are affected differently, such as exhaust gases from thermal power plants, chemical plants, etc., are corrosive, and are likely to corrode the jackets or metal strands of the cable; the ADSS optical cable sections at hillsides, valleys and other areas are easy to form strong wind due to topography, and are easy to be influenced by wind power to generate damage; ADSS optical cable sections in forest fields, target ranges and the like are easily damaged by artificial external force.

Therefore, the method analyzes the image in the area where the ADSS optical cable is located by generating the target acquisition area corresponding to the connecting line corresponding to the ADSS optical cable to obtain the attribute information in the target acquisition area, wherein the attribute information can be attributes of hillsides, thermal power plants, forest farms and the like, and then the ADSS optical cable is segmented according to the attribute information at different positions in the ADSS optical cable to obtain a plurality of first sub-connecting sections.

For example, if a river region, a valley region, or a forest farm region exists in the connecting line, the connecting line is divided into 3 first sub-connecting segments.

Through the embodiment, the connecting wires corresponding to the ADSS optical cable are divided into the plurality of first sub-connecting sections according to the actual conditions, so that corresponding operation and maintenance frequencies are conveniently configured for each first sub-connecting section, the actual conditions are more attached, and the fault rate of the ADSS optical cable is reduced.

In some embodiments, in step S2 (generating a target acquisition area corresponding to the connection line, performing information acquisition on a target acquisition image in the target acquisition area to obtain attribute information of the corresponding target acquisition area, segmenting the connection line according to the attribute information at different positions of the connection line to obtain a plurality of first sub-connection segments), the method includes S21-S24:

S21, obtaining the lengths of connecting lines of two connected power transmission and transformation equipment position points to obtain a first length, and generating a rectangular target acquisition frame according to the preset width and the first length.

It is easy to understand that the length of the connecting line between the two connected power transmission and transformation equipment position points is obtained, and a first length is obtained, wherein the first length is the length of the corresponding ADSS optical cable.

Further, under the condition that the first length is determined, a rectangular target acquisition frame is generated at two ends of the connecting line respectively with preset widths, wherein the preset widths can be set manually according to actual conditions, for example, 10 meters, 20 meters and the like.

In some embodiments, in step S21 (obtaining the lengths of the connecting lines of the two connected power transmission and transformation device location points to obtain a first length, and generating a rectangular target acquisition frame according to a preset width and the first length), the steps include S211-S212:

s211, generating a transparent upper layer diagram corresponding to the geographic information image, and carrying out coordinate processing on the geographic information image and the upper layer diagram so that corresponding pixel points in the geographic information image and the upper layer diagram have the same coordinates.

It can be understood that the invention can generate the transparent upper layer diagram consistent with the geographic information image, and simultaneously coordinate the geographic information image and the upper layer diagram, which correspond to the same coordinate system, so that the pixels at the same position in the geographic information image and the upper layer diagram have the same coordinates.

S212, obtaining the length of a connecting line of two connected power transmission and transformation equipment position points to obtain a first length, and generating a rectangular target acquisition frame with preset pixel values in an upper layer diagram according to the preset width and the first length.

It will be appreciated that after determining the length of the connection line, a rectangular target acquisition frame is generated in the upper layer chart with a preset width, and the target acquisition frame is displayed with a preset pixel value, for example, red, purple, etc., which is not limited herein.

It should be noted that in the prior art, the image processing is directly performed on the geographic information image, a large number of processing traces, such as region division, image replacement, etc., are generated, the whole image is processed, the whole image needs to be traversed in each processing, and the processing amount is large. The preset width is a manually preset width, and the value of the preset width is generally smaller, so that the subsequent segmentation processing is convenient.

S22, determining a first width edge and a second width edge of the target acquisition frame, a first midpoint of the first width edge and a second midpoint of the second width edge, and connecting the first midpoint and the second midpoint to obtain a first calibration line.

It will be appreciated that referring to fig. 2, the center points (the first midpoint and the second midpoint) on the width edge of the target acquisition frame are determined and connected to obtain the first calibration line in the target acquisition frame, so that the first calibration line and the connecting line are conveniently overlapped and arranged subsequently, and thus the area where the ADSS optical cable is located, and the target acquisition frame is utilized to extract an image of the area.

S23, adjusting the position of the target acquisition frame based on the first calibration line and the connecting line so that the first calibration line and the connecting line are overlapped, and taking the area in the geographic information image corresponding to the target acquisition frame as a target acquisition area.

It can be appreciated that the first calibration line in the target acquisition frame and the connecting line of the ADSS optical cable are arranged in a superposition manner, so that the connecting line is positioned in the target acquisition frame, and the target acquisition frame is utilized to extract images of the region.

Through the embodiment, the connecting line is positioned in the target acquisition frame, the target acquisition frame is positioned in the upper layer diagram, the corresponding target acquisition area is conveniently and directly extracted through the coordinate point in the target acquisition frame in the upper layer diagram, and the subsequent processing is carried out.
