Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] According to research, the current power grid engineering substation design uses CAD drawing software to form a preliminary plan based on previous design plans and information, and then makes modifications in the preliminary plan based on the transformer equipment model provided by the equipment manufacturer's drawings. When a certain equipment is changed, all other related design drawings such as plan layout drawings, cross-sectional drawings, and profile drawings need to be replaced, including the wires, cables, and devices connected to the equipment, which also need to be redrawn, greatly increasing the drawing workload. In addition, during the redesign process, there are problems such as time-consuming and labor-intensive equipment symbol replacement, complex equipment wire connections, cumbersome adjustment of annotation symbols, and easy errors in manual adjustments.

[0063] Based on the above research, the embodiment of the present disclosure provides a method for automatic equipment replacement, which uses automatic replacement to directly replace the manufacturer's equipment drawings into the drawings of the preliminary plan, thereby avoiding problems such as connection errors and dimensional deviations that may occur in the traditional manual replacement process, improving drawing efficiency and improving drawing quality.

[0064] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0065] See also Figure 1 , Figure 1The flowchart of the automatic equipment replacement method is shown. Through the equipment interface definition, it is matched with the preliminary plan, and finally the replacement equipment drawing is automatically generated. The substation professional design process based on the equipment replacement scenario is simplified, and the design process is standardized and normalized. It can be flexibly adjusted according to the equipment drawings and preliminary plans provided by different manufacturers. At the same time, it can also support more types of equipment and connection methods by expanding interface definitions and mapping rules, with high flexibility and scalability. It is consistent with the preliminary plan in terms of equipment interface, connection method, etc., to avoid problems such as connection errors and size deviations that may occur in the traditional manual replacement process, improve drawing efficiency and drawing quality.

[0066] In at least one embodiment, the method for automatic device replacement includes:

[0067] S110: Obtain a new device drawing, and define an interface of the new device in the new device drawing.

[0068] Specifically, the steps of defining the interface of the device in step S110 include:

[0069] S111: Select a new device graphic.

[0070] Specifically, select the required equipment graphics based on the equipment drawings provided by the manufacturer.

[0071] S112: Define the view type of the new device graphics.

[0072] Specifically, the view types include the following: plan view, front view, and side view.

[0073] S113: Define the replacement base point of the new equipment graphic.

[0074] Specifically, the replacement base points of the plan view, main view and side view are defined to ensure more accurate replacement.

[0075] S114: Define the interface of the new device graphics.

[0076] Specifically, the interfaces of the equipment graphics are divided into the following types: high-pressure side interface, medium-pressure side interface, low-pressure side interface, center point interface, body center interface and oil pipe installation height interface.

[0077] Each equipment diagram includes one or a combination of a high-pressure side interface, a medium-pressure side interface, a low-pressure side interface, a center point interface, a body center interface, and an oil pipe installation height interface.

[0078] Through the above interface definition content, the location of each interface of the equipment is determined, providing a basis for automatically generating equipment replacement drawings.

[0079] S120: Obtain a preliminary plan, and associate and match the interface defined in the new equipment drawing with the interface of the equipment drawing in the preliminary plan.

[0080] Specifically, step S120 includes the following steps:

[0081] S121: Sort out the association relationships between the devices in the preliminary plan and build connection rules.

[0082] The process of determining the association relationship is as follows:

[0083] Each interval symbol in the preliminary plan corresponds to a different device, and the different devices are associated with the corresponding device type, model, specification and other parameter information, and the topological relationship between the devices connected by conductors is determined, and the position arrangement relationship between similar devices is recorded.

[0084] Specifically, the connection rules include: connection rules between devices and wires, and between devices; automatic drawing rules for line devices; and automatic generation rules for block devices.

[0085] It should be noted that the connection rules must meet the requirements of the power engineering substation professional design specifications.

[0086] The connection rules between devices and wires and between devices include the connection rules between interfaces and linear devices and the connection rules between interfaces and block devices.

[0087] Specifically, the connection rules between the interface and the linear device include:

[0088] A combination of one or more of the high-pressure side interface connection rules, the medium-pressure side interface connection rules, the low-pressure side interface connection rules, the center point interface connection rules, the body center interface connection rules, and the oil pipe installation height interface connection rules.

[0089] The following are some connection rules:

[0090] The high-voltage side interface connection rules are as follows: Figure 2 shown.

[0091] The low voltage side interface connection rules are as follows: Figure 3 shown.

[0092] The connection rules of the central interface of the device body are as follows Figure 4 shown.

[0093] The oil pipe installation height interface connection rules are as follows Figure 5 shown.

[0094] The steps of the automatic drawing rules of the linear equipment include: obtaining the type of linear equipment; respectively obtaining the point coordinates of each phase of the three-phase line in the interface in the equipment drawing; setting the corresponding origin relative position coordinates; calculating the first positioning point coordinates based on the corresponding origin relative position coordinates and the point coordinates; obtaining the coordinates of all relative position points based on the corresponding origin relative position coordinates and the coordinates of the positioning point.

[0095] Among them, the types of linear equipment include cables, busbars, wires, and conductors.

[0096] The automatic drawing rules of line type devices are as follows Figure 6 shown.

[0097] The steps of automatically generating rules for tile devices include: obtaining the type of tile devices; respectively obtaining the point coordinates of all tile devices in the interface; setting the origin relative position coordinates of the tile devices; calculating the first positioning point coordinates according to the point coordinates of the corresponding tile devices and the origin relative position coordinates of the tile devices; and calculating the relative position coordinates of all tile devices according to the point coordinates of the tile devices and the origin relative position coordinates of the tile devices.

[0098] Among them, the types of block equipment are support insulators, columns, brackets, steel sections, etc. Each type of equipment corresponds to a different block.

[0099] Specifically, the automatic generation rules of tile devices are as follows: Figure 7 shown.

[0100] S122: Establish a mapping plan based on the interface defined in the new equipment drawing and the connection rules between the equipment in the preliminary plan.

[0101] Specifically, based on the analysis of the drawing data in the preliminary plan, a mapping relationship between the two parties is established, with the interval symbol corresponding to the equipment graphics, the interval information corresponding to the equipment parameters, the interval symbol connection corresponding to the equipment connection relationship, etc., to build a device connection topology relationship model.

[0102] S123: According to the mapping plan, the interfaces defined by the manufacturer's equipment are associated and matched with the equipment interfaces in the preliminary plan.

[0103] S130: Based on the result of the association matching, the new equipment drawing automatically replaces the equipment drawing in the preliminary plan, thereby completing the automatic replacement.

[0104] Specifically, based on the device connection topology model and combined with the device interface mapping rules, the automatic replacement of the manufacturer's device graphics is achieved. Its topology remains unchanged, providing a basis for subsequent digital applications.

[0105] Automation: Automatically analyze the data information in the preliminary plan and extract key parameter information. Automatically build the device connection topology relationship model.

[0106] Convenience: Topological relationship model data can be exported and applied digitally. It can adjust device graphics according to user's specific needs and provide customized solutions to meet different application scenarios and needs.

[0107] S140: Automatically generate line devices and block devices.

[0108] Specifically, according to the mapping scheme that matches the interface of the defined equipment with the preliminary scheme, the design elements such as equipment, wires, cables, and devices are automatically connected. Based on the connected design drawings, the annotation content is automatically generated. The overall equipment position and layout meet the design requirements in the preliminary scheme, and the substation professional design drawings after the equipment is replaced are automatically generated.

[0109] S150: Output drawings.

[0110] Figure 8 The following is a schematic diagram of the device wiring diagram after automatic replacement as an example.

[0111] Since the size of the equipment drawings provided by the manufacturer is different from the drawings in the preliminary plan, the large-sized equipment cannot be directly replaced with the drawings in the preliminary plan, and the original space layout cannot meet the placement requirements of the equipment. Therefore, in order to ensure that the equipment drawings can be replaced with the drawings in the preliminary plan

[0112] like Fig. 9 As shown, in at least one embodiment, step S130 includes the following steps:

[0113] S131: Based on the result of the association matching, the new equipment drawing is translated to the design position of the corresponding equipment in the preliminary plan.

[0114] S132: Calculate the distance between the new equipment and the surrounding walls in the civil engineering layer of the corresponding equipment in the preliminary plan;

[0115] S133: Compare the distance between the new equipment and the surrounding walls with the designed distance;

[0116] S134: If the distance between the new device and the surrounding walls is greater than or equal to the designed spacing, the automatic replacement is completed and the process proceeds to step S140 and step S150; if the distance between the new device and the surrounding walls is less than the designed spacing, the process proceeds to step S135.

[0117] S135: Adjust the position of the new device. After the adjustment is completed, proceed to step S140 and step S150.

[0118] Wherein, step S135 includes the following steps:

[0119] S1351: Extend the four sides of the new equipment outward by the length of the design spacing to form a polygonal design space.

[0120] Among them, the polygonal design space is as follows Fig.10 shown.

[0121] S1352: Obtain the location space of the polygon where the corresponding device is located in the preliminary plan.

[0122] S1353: Overlap the center point of the design space with the center point of the position space, and rotate the design space with the center point of the design space as the center of the circle;

[0123] S1354: If the position space completely covers the design space when rotated to angle α, the position of the new device is adjusted at angle α. After the adjustment is completed, enter step S140 and step S150. Fig.11 As shown; if after rotating 360°, the position space cannot cover the design space, then go to step S1355.

[0124] S1355: Rotate the design space with the center point of the design space as the rotation point, and record the rotation angle β when the design space exceeds the minimum area of ​​the position space, calculate the distance that the design space exceeds the position space at this time, and record it as the new wall distance, such as Fig.12 As shown, arrows F1 and F2 are the directions in which the wall moves.

[0125] S1356: Adjust the surrounding walls of the location space according to the new wall distance, and store the drawings of the adjusted preliminary plan to the server, complete the adjustment, and proceed to step S140 and step S150.

[0126] in, Fig.13 This is a schematic diagram of the spatial layout of the preliminary plan. Fig.14 This is a schematic diagram of the space layout after the equipment is automatically replaced.

[0127] At least one embodiment further provides a computer storage medium, on which a computer program is stored, and when the computer program is executed by a processor, the steps of the service solution selection method described in the above method embodiment are executed. The storage medium may be a volatile or non-volatile computer-readable storage medium.
