Description

Technical Field

[0001] The present application relates to the technical field of power operating systems, and in particular to a mobile terminal retrieval method and system based on an incremental diagram of a distribution network single-line diagram. Background Art

[0002] my country's power grid system is one of the largest in the world and is still in a stage of sustained growth. It is also improving the intelligence level and operating efficiency of the power grid through digitalization, networking, and intelligentization technologies.

[0003] In order to help staff members intuitively understand the structure and connection mode of the power grid, the power grid equipment is combined with the topology diagram to form a power grid topology diagram, which is applied in my country's power grid operating system. It graphically displays the connection relationship between each substation, power plant and the transmission line between them in the power grid. This graphical representation method helps to intuitively understand the structure and connection mode of the power grid, so as to better plan, operate and maintain the power grid.

[0004] When there are new devices in the power grid system, the operator needs to reflect the new devices in the power grid topology diagram, that is, to create a new unit in the power grid topology diagram. The new unit represents the new devices and establishes a connection between the new unit and other units in the power grid topology diagram based on the connection relationship between the new devices and other devices.

[0005] However, after each new unit is formed, a graphic increment will be formed on the power grid topology map, causing the initial unit (the unit that existed before the update) in the power grid topology map to shift in position. If the position shift of the initial unit is too large, when the operator performs equipment calibration or maintenance and views the updated power grid topology map through a mobile terminal, it is difficult to find the initial unit with a position shift in a short time, which increases the time it takes for the operator to adapt to the updated power grid topology map. Summary of the invention

[0006] In order to shorten the adaptation time of operators to the updated power grid topology diagram, the present application provides a mobile terminal retrieval method and system based on the incremental diagram of the distribution network single-line diagram.

[0007] In the first aspect, the mobile terminal retrieval method based on the incremental diagram of the distribution network single-line diagram provided by the present application adopts the following technical solution:

[0008] A mobile terminal retrieval method based on a distribution network single-line diagram incremental diagram includes the following processing steps:

[0009] Obtain the power grid topology map of the target area;

[0010] Gridding the power grid topology map to form a topology grid map;

[0011] Recording the initial position of each initial unit in the topological grid map;

[0012] Obtaining a connection relationship between the newly created unit and the initial unit;

[0013] Based on the connection relationship, the newly created unit is loaded into the topological grid map;

[0014] The changed position of each initial unit in the updated topological grid map is obtained. If the changed position of the initial unit exceeds a preset visible range, the position of the initial unit exceeding the visible range is similarly restored.

[0015] Through the above technical solution, after obtaining the power grid topology map of the target area, it is gridded to form a topological grid map, so that each unit of the power grid topology map can fall into different grids in the topological grid map, so that each unit can obtain a unique position and have clear position information in the topological grid map, which is convenient for later changes and adjustments.

[0016] Then, the initial position (referring to the position of the initial unit in the topological grid map before the position is adjusted) of each initial unit (i.e., corresponding to different devices in the power grid system) is recorded to facilitate later judgment on whether the grid of the initial unit exceeds the visual range of the operator.

[0017] Based on the connection relationship between the newly created unit (that is, the newly added device, which can be one or more, which can replace the original device or connect a new device) and the initial unit, the newly created unit is virtualized and loaded into the topological grid map, which may squeeze the grid space of the initial unit and change the position of the initial unit. The change in the position of the initial unit is reflected in the topological grid map as the initial unit is squeezed and migrated from the grid where the initial position is located to other vacant grids, thereby generating a changed position (referring to the position after the change).

[0018] Since a visible range is set in advance for the initial position of the initial unit (the visible range is usually set to a rectangle, which can be understood here as a rectangular frame composed of multiple continuous grids, and the initial position of the initial unit is located at the center of the visible range. Beyond the visible range, it will be difficult for the operator to accurately find the initial unit), then, if the changed position of the initial unit is not within the visible range, then the position of the initial unit is similarly restored, that is, according to a certain adjustment logic, the initial unit is adjusted to an area that is easy for the operator to find quickly. The above adjustment logic will be described in detail later.

[0019] By comparing the post-transformation position of the initial unit to see if it exceeds the visible range of the initial position, the operator can determine whether the post-transformation position of the initial unit is accurate, and then determine whether the position of the initial unit needs to be similarly restored. After the position similarity restoration, the operator can search for the initial unit according to the logic of position adjustment, which shortens the operator's adaptation time to the updated power grid topology and improves work efficiency.

[0020] In a preferred example, the present application may be further configured as follows: gridding the power grid topology map to form a topology grid map, including:

[0021] In the power grid topology diagram, a positioning coordinate system is placed;

[0022] Based on the unit scale of the positioning coordinate system, forming a plurality of grids;

[0023] Scaling each initial unit icon on the power grid topology map so that the size of each initial unit is consistent with the size of the grid;

[0024] The positional relationship between each initial unit on the power grid topology diagram is adjusted nearby so that each initial unit falls into a different grid.

[0025] Through the above technical solution, a positioning coordinate system is placed in the power grid topology map. The above positioning coordinate system can be a two-dimensional coordinate system. There are unit scales on the horizontal and vertical axes of the positioning coordinate system. The power grid topology map is divided into multiple grids with orthogonal lines where the unit scales are located, thereby forming a topological grid map.

[0026] Then, the icons on the power grid topology map are scaled so that the size of each initial unit is consistent with the grid size. Then, without changing the connection relationship and visual relationship between the initial units, the position relationship between the initial units is adjusted nearby (here, the nearby adjustment can be understood as adjustment within the visual range of the initial position) so that the initial units fall into different grids.

[0027] In a preferred example, the present application may be further configured such that the similar restoration of the position of the initial unit beyond the visible range includes:

[0028] Obtaining an initial unit beyond the visible range, an initial position in the topological grid map and a visible range of the initial unit, and obtaining a root unit of the initial unit, a current position in the topological grid map;

[0029] Obtain the center coordinate one of the grid where the root unit is located, and obtain the coordinates of two endpoints of the diagonal line of the visible range that does not point to the root unit;

[0030] Taking the center coordinate 1 as the starting point and the line connecting the center coordinate 1 and the two end point coordinates as the boundary, a radial area is formed;

[0031] Generate a triangular area based on the center coordinate one and the two endpoint coordinates;

[0032] Excluding the triangular area in the radiation area to form a reduction area;

[0033] The initial unit is placed in a grid within the restoration area and outside the visible range.

[0034] Through the above technical solution, the above root unit refers to a unit represented in the topological grid diagram by a connected device one level or multiple levels before the initial unit. During actual operation, a unit of a previous level can be designated as the root unit.

[0035] The center coordinate of the root unit refers to the coordinate of the intersection of the diagonal lines of the grid where the root unit is located. The endpoint coordinates refer to the coordinates of the intersection of the diagonal line of the visible range rectangle that does not point to the corresponding root unit and the visible range rectangle. It can be simply understood as the coordinates of the two intersections of the diagonal line and the rectangle.

[0036] Connecting the two endpoint coordinates and the center coordinate one with a straight line will form a fan-shaped radial area with the center coordinate one as the starting point, and connecting the two endpoint coordinates and the center coordinate one with a straight line will form a closed triangular area, which is completely within the radial area. After excluding the triangular area from the radial area, the remaining area is called the restoration area. At this time, the initial unit that exceeds the visible range can be adjusted to the grid within the restoration area and outside the visible range, so that the operator can search for the initial unit according to this logic.

[0037] It should be noted here that the reason why the placement grid of the initial unit is not matched directly up and down in the visible range is that grid spaces need to be reserved for subsequent new units to reduce the possibility of topological grid disorder. The reason why the placement grid is not matched in the visible range is that during the process of loading the new unit, the position conflict between the new unit and the initial unit has occurred.

[0038] In a preferred example, the present application may be further configured as follows: placing the initial unit in a grid within the restoration area and outside the visible range includes:

[0039] Obtaining the center coordinate 1 and the center coordinate 2 of the grid where the initial position of the initial unit is located;

[0040] Based on the center coordinate 1 and the center coordinate 2, a priority restoration straight line is generated;

[0041] The initial unit is placed in the nearest restoration area grid through which the priority restoration line passes.

[0042] Through the above technical solution, according to the center coordinate one and the center coordinate two, a straight line is used to connect the two. The straight line is called the priority restoration line. The nearest restoration area grid passed by the priority restoration line can be used to place the initial unit.

[0043] Due to the operator's original operating habits and visual habits, they will look in the direction from the root unit to the initial unit, that is, in the direction of prioritizing the restoration of the straight line. By continuing this search habit, the operator can quickly find the initial unit position after the position adjustment.

[0044] In a preferred example, the present application may be further configured such that, if there are other cells in the restoration area grid through which the priority restoration line passes, the other cells are skipped and the preferred grid is continued to be matched for the initial cell.

[0045] Through the above technical solution, if there are other cells in the restoration area grid passed by the priority restoration line, then skip the other cells and continue to match the preferred grid for the initial cell. The other cells here refer to the root cells or initial cells that have occupied the restoration area grid. The reason why the other cells need to be skipped is that it is necessary to retain the initial positions of each cell in the power grid topology as much as possible, so that the operator can find the location of the cell according to the previous operating habits, further improving work efficiency.

[0046] In a preferred example, the present application may be further configured such that if the priority restoration straight line only passes through an inflection point of a grid without the other units, the grid is used as the preferred grid of the initial unit.

[0047] The above-mentioned inflection points refer to the four corner points of the grid. Through the above-mentioned technical solution, although the priority restoration straight line does not pass through the preferred grid referred to here, it is still within the sight range that the operator can quickly capture, so it can help the operator quickly find the location of the initial unit.

[0048] In a preferred example, the present application can be further configured as follows: if the priority restoration straight line only passes through the common points of two grids with overlapping diagonal lines in the same direction, the grid farthest from the root unit is used as the preferred grid of the initial unit.

[0049] Through the above technical solution, the two common point grids referred to here refer to adjacent grids where one grid is located at 45 degrees to the center point of the other grid. The grid farthest from the root unit is used as the preferred grid for the initial unit because this not only allows the initial unit to find a placement grid, but also allows a certain amount of space to be reserved for accommodating subsequent new units.

[0050] In the second aspect, based on the above-mentioned mobile terminal retrieval method based on the incremental diagram of the distribution network single-line diagram, the present application also provides a mobile terminal retrieval system based on the incremental diagram of the distribution network single-line diagram, which adopts the following technical solution:

[0051] A mobile terminal retrieval system based on a single-line diagram incremental diagram of a distribution network, comprising:

[0052] Information acquisition module: used to obtain the power grid topology map of the target area;

[0053] A topology map generation module is used to perform grid processing on the power grid topology map to form a topology grid map;

[0054] Recording module: used for recording the initial position of each initial unit in the topological grid map;

[0055] Information acquisition module: used to obtain the connection relationship between the newly created unit and the initial unit;

[0056] Unit loading module: based on the connection relationship, loading the newly created unit into the topological grid map;

[0057] Similarity restoration module: obtains the changed position of each initial unit in the updated topological grid map, and if the changed position of the initial unit exceeds a preset visible range, performs position similarity restoration on the initial unit that exceeds the visible range.

[0058] In summary, this application includes the following beneficial technical effects:

[0059] 1. After the initial units beyond the visual range of the initial position are restored to a similar position, the operator can find the initial units according to the adjustment logic of the position, which shortens the operator's adaptation time to the updated power grid topology map and improves work efficiency.

[0060] 2. The grids that the straight line passes through are restored first as the basis for selecting the optimal grid. On the basis of retaining the operator's habit of finding the initial unit, the search logic is continued, which can help operators further shorten the adaptation time to the updated power grid topology map;

[0061] 3. Fully consider the special situation of giving priority to restoring the straight line passing through the grid inflection point, further improve and enhance the logic of initial unit position adjustment, so as to improve the stability of the system running this method.

[0073] The following is combined with Figure 1 -Attached Fig. 9 This application is described in further detail.

[0074] In an embodiment of the present application, a method and system for mobile terminal retrieval based on an incremental diagram of a distribution network single-line diagram are disclosed. During equipment calibration or maintenance, operators can retrieve a power grid topology diagram processed by the method through a mobile terminal, thereby shortening the operator's adaptation time to the updated power grid topology diagram and improving work efficiency.

[0075] See attached Figure 1 and attached Figure 5 As shown, a mobile terminal retrieval method based on the incremental diagram of the distribution network single-line diagram includes the following processing steps:

[0076] S101. Obtain a power grid topology map of a target area.

[0077] In implementation, the area where the updated equipment is located, that is, the target area, obtains the power grid topology map of the target area, which can be used as a basis for subsequent map model processing.

[0078] S102, gridding the power grid topology map to form a topological grid Figure 1 .

[0079] In the implementation, the grid topology map is gridded to form a topological grid. Figure 1 In the subsequent S2 step, combined with the attached Figure 5 , there is a detailed description, which will not be repeated here.

[0080] S103. Recording topological grid Figure 1 The initial position of each initial unit in is 11.

[0081] In the implementation, the initial unit refers to the unit representation of the existing equipment in the power grid topology diagram, and the initial position 11 referred to here refers to the topological grid Figure 1 The initial unit is formed and the initial unit is adjusted to the initial position 11. The initial position 11 is the newly created unit loaded into the topology grid. Figure 1 The final position before.

[0082] S104: Obtain the connection relationship between the newly created unit and the initial unit.

[0083] In implementation, the newly created unit refers to the unit representation of the updated device in the power grid topology diagram, and the connection relationship between the newly created unit and the initial unit is obtained. For example, if a device is used to control the switch of another device or the adjustment of operating parameters, then such a relationship is regarded as the connection relationship between the two.

[0084] S105. Based on the connection relationship, the newly created unit is loaded into the topological grid Figure 1 middle.

[0085] In practice, this can be understood as virtualizing the update device into a new unit in the topology grid. Figure 1 In the diagram, it is represented as a two-dimensional or three-dimensional visual icon, and according to the connection relationship, the icon of the newly created unit is connected to establish the connection relationship between the newly created unit and the existing unit, so as to intuitively display the relationship and operating status between the updated device and the existing device.

[0086] S106. Obtaining the updated topological grid Figure 1 The changed position of each initial unit in the image is restored. If the changed position of the initial unit exceeds the preset visual range 12, the position of the initial unit exceeding the visual range 12 is restored similarly.

[0087] In practice, since the newly created unit loads the topological mesh Figure 1 This may squeeze the grid space where the initial unit is located, causing the position of the initial unit to change, and in the topological grid Figure 1 It is reflected in that the initial unit is squeezed and migrated from the grid where the initial position 11 is located to other free grids, and the grid where the initial unit is located after being forced to migrate is the post-change position.

[0088] In the present method, the visual range 12 is a rectangular box composed of a plurality of continuous grids. The initial position 11 of the initial unit is located at the center of the visual range 12. Beyond the visual range 12, it is difficult for the operator to accurately find the initial unit. The determination of the visual range 12, that is, the determination of the size of the rectangular box, is determined based on the range that the operator's vision can quickly capture. The size can be preset or set individually for different operators.

[0089] If the changed position of the initial unit exceeds the visible range 12 (the visible range 12 is shown as a 3*3 grid in the attached figure), the position of the initial unit is similarly restored. That is, the initial unit is adjusted to an area that is easy for the operator to find quickly according to a certain adjustment logic. The above adjustment logic will be described in detail later.

[0090] This method performs similar restoration of the position of the initial unit that is beyond the visible range 12. Since the operator has pre-defined the adjustment logic of the initial unit position, the operator searches for the initial unit according to the logic, which shortens the operator's adaptation time to the updated power grid topology map and improves work efficiency.

[0091] See attached Figure 2 , Attachment Figure 5 And attached Figure 6 As shown, in step S102, the power grid topology map is gridded to form a topological grid. Figure 1 , including the following processing steps:

[0092] S201. In the power grid topology diagram, a positioning coordinate system 3 is placed.

[0093] In implementation, the positioning coordinate system 3 refers to a two-dimensional coordinate system with a horizontal axis and a vertical axis perpendicular to each other. The origin of the coordinate system can be set at a boundary point farther away from the power grid topology map, and the icons of each initial unit can fall in the first quadrant. In order to achieve more refined management, the origin of the coordinate system can be set at the center point of the power grid topology map, so that the icons of each initial unit can be distributed in each quadrant. The following is only an explanation of the distribution in the first quadrant.

[0094] S202 , forming a plurality of grids based on the unit scale of the positioning coordinate system 3 .

[0095] In the implementation, the horizontal axis and the vertical axis have uniform unit scales, and the orthogonal straight lines where each unit scale is located are used as dividing lines to divide the power grid topology map into multiple grids, thereby forming a topological grid. Figure 1 .

[0096] S203: scaling each initial unit icon on the power grid topology map so that the size of each initial unit is consistent with the size of the grid.

[0097] During implementation, each initial unit icon is scaled so that the size of the initial unit is consistent with the size of the grid, so that the initial unit can be placed in the grid, that is, a one-to-one correspondence between a grid and an initial unit is formed, which improves management while also improving the visual experience.

[0098] S204, adjusting the positional relationship between the initial units on the power grid topology map so that the initial units fall into different grids.

[0099] In implementation, the positional relationship between the initial units is adjusted nearby. The nearby adjustment here can be understood as adjustment within the visible range 12 of the initial position 11, so that the initial units fall into different grids.

[0100] See attached Figure 3 , Attachment Figure 5 And attached Figure 6 As shown, in step S106, the position of the initial unit beyond the visible range 12 is similarly restored, including the following processing steps:

[0101] S301, obtain the initial unit beyond the visible range 12, in the topological grid Figure 1 The initial position 11 and the visual range 12 of the initial unit, and obtain the root unit 4 of the initial unit, in the topological grid Figure 1 The current position in .

[0102] In the implementation, the root unit 4 refers to a connected device one level or multiple levels before the initial unit in the topological grid. Figure 1 In the actual operation process, a previous level unit can be designated as the root unit 4.

[0103] S302 , obtaining the center coordinate 41 of the grid where the root unit 4 is located, and obtaining the two end point coordinates 121 of the diagonal line of the visible range 12 that does not point to the root unit 4 .

[0104] In implementation, refer to the attached Figure 5 and attached Figure 6 The center coordinates referred to in the following text are shown as circles in the attached figure. The center coordinates of the root unit 4, 41, refer to the coordinates of the intersection of the diagonal lines of the grid where the root unit 4 is located. The endpoint coordinates 121 refer to the coordinates of the intersection of the diagonal line of the visible range 12 in the rectangular box where the visible range 12 is located, which do not point to the coordinates of the intersection of the diagonal line corresponding to the root unit 4 and the rectangular box of the visible range 12, and can be simply understood as the coordinates of the two intersections of the diagonal line and the rectangular box.

[0105] S303, taking the center coordinate -41 as the starting point and the line connecting the center coordinate -41 and the two end point coordinates 121 as the boundary, a radiation area is formed.

[0106] In implementation, refer to the attached Figure 5 and attached Figure 6 , taking the center coordinate 41 as the starting point, using a ray to connect the center coordinate 41 and one of the endpoint coordinates 121, and using another ray to connect the center coordinate 41 and the other endpoint coordinate 121, a radiation area is formed. The shape of the radiation area is similar to a less than sign ("<"), which is shown in the attached figure. Because the shape overlaps with other graphics, it is marked.

[0107] S304, based on the center coordinate 41 and the two endpoint coordinates 121, generate a triangular area 5.

[0108] In implementation, refer to the attached Figure 5 and attached Figure 6 , with the center coordinate 41 and the two end point coordinates 121, which are the three vertices of the triangle, forming a triangular area 5. The tip part of the triangular area 5 and the radial area overlap with each other, that is, the triangular area 5 completely belongs to the subset of the radial area.

[0109] S305 , excluding the triangular area 5 in the radiation area to form a reduction area 6 .

[0110] In practice, after excluding the triangular area 5 from the radiation area, that is, subtracting the area range of the triangular area 5 from the area range of the radiation area, the remaining area is called the restoration area 6.

[0111] S306 , placing the initial unit in a grid within the restoration area 6 and outside the visible range 12 .

[0112] In implementation, the initial units beyond the visible range 12 are adjusted to a grid within the restoration area 6 and outside the visible range 12, so that the operator can search for the initial units according to this logic.

[0113] It should be noted here that the reason why the placement grid of the initial unit is not matched directly up and down within the visible range 12 is that grid spaces need to be reserved for subsequent new units to reduce the topological grid Figure 1 The possibility of confusion.

[0114] The reason why the grid is not matched and placed within the visible range 12 is that during the process of loading the new unit, a position conflict between the new unit and the initial unit has occurred.

[0115] See attached Figure 4 , Attachment Figure 5 , Attachment Figure 6 And attached Figure 7 As shown, in step S306, the initial unit is placed in a grid within the restoration area 6 and outside the visible range 12, including the following processing steps:

[0116] S401, obtaining a center coordinate 1 41 and a center coordinate 2 111 of a grid where an initial position 11 of an initial unit is located.

[0117] S402 , based on the center coordinate 1 41 and the center coordinate 2 111 , generate the priority restoration straight line 7 .

[0118] In implementation, according to the center coordinate 1 41 and the center coordinate 2 111 , a straight line is used to connect the two, and the straight line is called the priority restoration straight line 7 .

[0119] S403, placing the initial unit in the nearest restoration area 6 grid through which the priority restoration line 7 passes.

[0120] In practice, the nearest restoration area 6 grid that the priority restoration line 7 passes through can be used to place the initial unit. Due to the original operating and visual habits of the operator, they will look in the direction from the root unit 4 to the initial unit, that is, in the direction of the priority restoration line 7. By continuing this search habit, the operator can quickly find the initial unit position after the position adjustment.

[0121] See attached Figure 5 and attached Figure 6 As shown, if there are other cells in the grid of the restoration area 6 through which the priority restoration line 7 passes, the other cells are skipped and the preferred grid is continuously matched for the initial cell.

[0122] The other units here refer to the root unit 4 or the initial unit that has occupied the grid of the restoration area 6. The reason why the other units need to be skipped is that it is necessary to retain the initial position 11 of each unit in the power grid topology diagram as much as possible, so that the operator can find the location of the unit according to the previous operating habits, thereby further improving work efficiency.

[0123] See attached Figure 5 and attached Figure 8 As shown in the figure, if the priority restoration straight line 7 only passes through the inflection point of a grid without other units, then the grid is used as the preferred grid of the initial unit. The above-mentioned inflection points refer to the four corner points of the grid. Although the priority restoration straight line 7 does not pass through the preferred grid referred to here, it is still within the sight range that the operator can quickly capture, so it can help the operator quickly find the location of the initial unit.

[0124] See attached Figure 5 and attached Fig. 9 As shown, if the straight line 7 is restored preferentially and only passes through the common points of two grids whose diagonals in the same direction coincide, the grid farthest from the root unit 4 is used as the preferred grid of the initial unit.

[0125] The two common point grids referred to here refer to adjacent grids where one grid is located at 45 degrees to the center point of the other grid. The grid farthest from the root unit 4 is selected as the preferred grid for the initial unit because it not only finds a placement grid for the initial unit, but also reserves a certain amount of space to accommodate subsequent new units.
