In the drawings, like reference numbers can indicate functionally identical or similar elements. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.
Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present application. It will be understood by those skilled in the art that the present application may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present application.
Fig. 1 shows a flow chart of a statistical method for quadratic cable length based on digitized three-dimensional technology according to an embodiment of the present application. As shown in fig. 1, the method includes: and S100, extracting a three-dimensional design drawing of the transformer substation, which needs to carry out secondary cable length statistics currently. And step S200, acquiring the cable information of the transformer substation, which needs to be subjected to the secondary cable length statistics currently. Then, in step S300, a cable laying result is automatically generated according to the three-dimensional design drawing of the substation and by combining the cable information. Finally, in step S400, the length of the secondary cable is obtained and recorded according to the cable laying result.
Therefore, according to the method for counting the length of the secondary cable based on the digital three-dimensional technology, the cable is laid automatically by combining the three-dimensional design drawing of the transformer substation, which is required to count the length of the secondary cable at present, with the cable information in the transformer substation, and after a cable laying result is obtained, the length of the secondary cable is calculated automatically according to the obtained cable laying result. Due to the fact that the three-dimensional design drawing of the transformer substation is combined with the cable information, the simulation of cable laying can be conducted through the combination of the three-dimensional design drawing and the cable information when the statistical calculation of the cable length is conducted. The simulated cable laying result comprises the space positions of the devices at the starting points and the end points arranged in the transformer substation project and the path of the cable laying channel, so that the length of the cable can be directly counted according to the cable laying result without manual calculation, automatic counting of the secondary cable in the transformer substation project is effectively achieved, and the counting efficiency of the length of the cable is effectively improved finally.
It should be noted that the cable information includes at least one of a cable type, a name, a model, a voltage class, a specification, and a cross-sectional outer diameter.
In a possible implementation manner, the cable information in the substation, where the secondary cable length is to be counted currently, may be obtained by extracting from a cable inventory provided by a substation engineering designer. Here, as can be understood by those skilled in the art, the cable inventory corresponding to the three-dimensional design drawing of the substation includes various pieces of parameter information in the substation project, such as: serial number, cable model, cable specification, starting point number, end point number, cable length, cable path, protective tube length, and the like. Meanwhile, as will be understood by those skilled in the art, the cable inventory may directly take the form of a table to record and store the relevant parameter information.
Further, in the method according to the embodiment of the present application, referring to fig. 2, when the cable information of the substation is extracted from the cable inventory corresponding to the three-dimensional design drawing of the substation, the cable inventory is synchronously generated by a substation designer when designing a substation project.
In the method of the embodiment of the application, the cable length can be directly counted and recorded based on the cable inventory provided by the designer when the secondary cable length is counted. That is, when the method of the embodiment of the present application is executed, first, in step S001, a cable inventory (format may be in the form of EXCEL table) of a substation project in which secondary cable length statistics is to be performed at present is obtained, and then, in step S002, corresponding columns in the inventory (i.e., a cable length column, a cable path column, a protection pipe length column, and the like for counting the secondary cable length) are identified and set. Therefore, the data template for counting and recording the length of the secondary cable can be completed, and the cable length counting template does not need to be edited again, so that the workload of certain data processing is reduced.
That is, in the method of the embodiment of the present application, the table for recording the cable length (i.e., the electrical secondary cable registration template) is performed based on the cable registration provided by the designer.
More specifically, the template for electrical secondary cable inventory may be set in an EXCEL form format, as shown in fig. 3. In the template for the electrical secondary cable inventory, the content of each column can be defined by the content attribute marked by the header. The content attribute of each column is used to characterize the data content of that column.
As shown in fig. 3, the electrical secondary cable inventory template for recording and counting cable lengths includes 10 rows, each row is: serial number, cable model, cable specification, starting point number, end point number, cable length, cable path and protective tube length. The cable length and the protective tube length are data parameter items added on the basis of the cable inventory provided by a designer.
After the electrical secondary cable registration template is established, the registration template is selected, and the cable information extracted from the system logic diagram is correspondingly picked into the secondary cable registration template according to the specific data content defined in each column of the secondary cable registration template, so that a corresponding secondary cable registration is obtained (as shown in fig. 4). Here, it can be understood by those skilled in the art that fig. 4 is only one example diagram of the established secondary cable inventory, and only part of the data content is shown in the example diagram.
Furthermore, the cable information extracted from the system logic diagram can be picked up in the secondary cable inventory in a corresponding matching manner. That is, fuzzy matching is performed according to the characters at the head of each list in the list, the content of each list in the list is determined, and the places where the matching is not correct can be corrected through manual adjustment.
Further, when the cable laying result is automatically generated according to the three-dimensional design drawing of the substation and by combining the cable information, the following method can be used for realizing the automatic generation of the cable laying result.
Firstly, correspondingly matching cable information into a three-dimensional design drawing of a transformer substation to obtain a three-dimensional topological drawing of the transformer substation. Here, the obtained three-dimensional topological diagram of the substation is a three-dimensional diagram obtained by correspondingly marking the cable information to a corresponding position on the basis of the three-dimensional design diagram of the substation. The three-dimensional topological graph of the transformer substation comprises at least one of the arranged space positions of the devices at the starting points, the space positions of the devices at the end points and the paths of the cable laying channels.
And then, according to the cable information, combining the topological graph to carry out cable laying simulation, and generating a cable laying result. Wherein the cabling results include results of cabling each cable into a designated layer of a cable trench support in the substation.
More specifically, according to the cable information, a topological graph is combined to perform cable laying simulation, when a cable laying result is generated, a cable trench support is firstly built based on preset support parameters and a cable trench path, and then each cable is laid to each specified layer of the cable trench support according to the cable information, the three-dimensional topological graph is combined to achieve cable laying simulation, and the cable laying result is obtained (as shown in fig. 6).
Fig. 7a and 7b are schematic diagrams respectively showing parameter setting interfaces according to which the cable trench support is generated in the statistical method for the length of the secondary cable based on the digital three-dimensional technology according to the embodiment of the present application. Wherein the stent parameters include: the support spacing, the elevation difference, the inner corner radius, the main frame top distance, the main frame bottom distance, the main frame material and the like can be specifically referred to fig. 7a and 7b, and an example is not given here.
Simultaneously, it still needs to point out that in the method of this application embodiment, when combining the cable pit route to build and generate the cable pit support according to predetermined support parameter, it builds and generates the rule and can adopt: and setting the bracket spacing and the bracket alignment mode according to the cable trench path and the corresponding cable bracket type configured by the cable trench attribute, and then building and generating the cable trench bracket by combining bracket parameters based on the set bracket spacing and the bracket alignment mode.
Here, it should also be noted that in the resulting cable trench support, the building of the cable trench joint is also included for the cable trench. The building and generating of the cable trench joint can be realized through automatic drawing and manual drawing. Referring to fig. 5, when automatic drawing is adopted, the straight cable trench is selected by frames, the outline is automatically generated, and the exit is automatically identified. When manual drawing is adopted, the outer contour of the connector can be drawn manually, and the outlet of the cable trench can be designated, so that the construction and the generation of the cable trench connector can be realized.
After the cable trench support is built, cables can be laid to the designated layer in the cable trench support according to cable information. In one possible implementation, the cables may be laid in a given layer of the cable trench support according to preset cabling rules.
Wherein, in the method of the embodiment of the application, the cabling rule comprises at least one of a cable layering rule and a volume ratio rule.
It should be noted that the cable layering rule is: different types of cables are correspondingly laid in the appointed layers of the cable trench support. I.e. the type matching of the cable to be laid to each specified layer in the trench support. The types of cables include, but are not limited to, power cables, control cables, and signal cables.
When the cables of various types are matched with the appointed layers in the cable trench support, the laying cable types of the appointed layers can be defined when the constructed cable trench support is subjected to parametric modeling after the construction of the cable trench support is completed. Therefore, when the cables are laid on the appointed layers of the cable trench support according to the cable layering rule, the cable types of the appointed layers which are defined in advance can be read, and then the corresponding cables are selected according to the cable information to be laid.
The volume ratio rule specifically means that the width of the cable laid on each specified layer in the cable trench support is adjusted to be smaller than or equal to the width of the support on the layer where the cable is located, and the number of support layers of the specified type of cable is set to be a preset number of layers.
That is, after cables are laid in the designated layers of the cable trench support according to the cable types, the cables laid in the designated layers are subjected to cable width setting, and the cable width of the cables is automatically adjusted to be not more than the support width of the layer where the cables are located. Meanwhile, the number of the support layers of the cable with the established type is correspondingly adjusted. The method specifically comprises the following steps: the number of the support layers for laying the control cable is not more than 3.
Further, after the cables are laid in the specified layers of the cable trench support based on the above two rules (i.e., the cable layering rule and the volume ratio rule), the paths of the cables need to be set accordingly. In one possible implementation, the cable path may be set in a shortest path manner.
Among them, as can be understood by those skilled in the art, the principle of the shortest path is: abstracting channels and equipment in the transformer substation engineering into paths and nodes, and then converting a cable path search problem into a problem of solving the shortest path between two nodes in graph theory. Here, it should be noted that the shortest path is intended to find the shortest path problem between two nodes in a topology composed of nodes and paths.
In the method of the embodiment of the present application, dijkstra (Dijkstra) algorithm is used, and the Dijkstra algorithm is a typical shortest path routing algorithm, is used for calculating the shortest path from one node to all other nodes, and is mainly characterized in that the shortest path is expanded layer by layer outward by taking a starting point as a center until the shortest path is expanded to a terminal point.
That is to say, in the method according to the embodiment of the present application, after the lengths of the secondary cables are counted to the designated layer of the cable trench support according to the cable layering rule and the volume ratio rule, the shortest path algorithm is adopted to plan the cable connection path, so that the automatic laying of the secondary cables is finally completed (as shown in fig. 8a and 8 b).
After the shortest path calculation rule is adopted to draw the path result of each laid secondary cable, the shortest path is not necessarily the best path, so that after the connection path of the secondary cables is planned, the connection path between the secondary cables can be optimized.
In a possible implementation manner, when the obtained cable connection path is optimized, the automatically generated cable connection path may be corrected according to a preset cable forced path. Here, as will be understood by those skilled in the art, the cable forcible path is a path in which the laying path of the cable is specified according to the actual situation.
When the automatically generated cable connection path is corrected according to the preset cable forced path, the shortest path of the corresponding road section can be directly replaced by the preset forced path.
After the secondary cables are laid by any one of the modes, the lengths of the cables can be obtained through statistics according to cable laying results, and the laid lengths of the cables are filled in the cable inventory template, so that the purpose of cable length statistics is achieved.
Here, it should be noted that, when the lengths of the cables laid are counted in the cable inventory template according to the cable laying result, the statistical rule of the lengths of the cables is as follows: the length of the topological graph path + the length of the starting and ending point from the cable channel + the additional length. Here, as can be understood by those skilled in the art, the length of the topology graph path refers to: the length of the cable channel from the starting point device to the end point device of the current section of cable. The length of the starting and ending point from the cable channel refers to the distance of the starting and ending point equipment of the current cable from the cable channel. The cable channel refers to a channel through which a cable needs to pass from a starting point to an end point, and generally refers to a cable trench, a cable bridge and the like. Additional length includes, but is not limited to, the following: 1. height difference changes of the cable laying path, expansion joints or roundabout standby allowances; 2. the increasing amount of the bending influence of the cable with more than 35kV during snake-shaped laying; 3. the termination or joint is made to cut off a reserved section of cable as required, the length of cable required to be routed to the equipment or device.
