[0002] With the development of society and the improvement of the level of safe and intelligent power use, more and more monitoring and protection devices are installed in electrical switchboards to support more advanced fault diagnosis and maintenance support functions. The increase in the number and complexity of these devices has led to an increasing number of secondary wires in electrical switchboards. To improve production efficiency, electrical switchboard manufacturers often use secondary wire design simulation software to perform the wire-off work through a fully automatic wire-off machine and carry out secondary wire prefabrication to improve production efficiency and reduce the time of secondary wire processing procedures.

[0003] The existing secondary wire design simulation software in the prior art all adopts a calculation method based on the center line of the wire. With the increase in the number of secondary wires, the size of the wire harness in the electrical switchboard is too large.

[0032] Furthermore, the described embodiments are only some of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and illustrated in the accompanying drawings here may be arranged and designed in various different configurations. Therefore, the detailed description of the embodiments of the present application provided in the accompanying drawings below is not intended to limit the scope of the present application claimed, but merely represents selected embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts fall within the protection scope of the present application.

[0033] It should be noted that the term "including" will be used in the embodiments of the present application to indicate the presence of the subsequently stated features, but does not exclude the addition of other features.

[0034] In the prior art, the calculation methods of the secondary wire design simulation software are all based on the center line of the wire. As the number of secondary wires increases, the size of the wire harness in the electrical panel cabinet becomes too large. As a result, when the wires in the wire harness turn, due to the inconsistent positions of the wires in the wire harness, there is a large error in the lengths of the wires located at the inner bend and the outer bend, making the calculation result of the wire length inaccurate. Moreover, the number of turns of the entire wire harness is relatively large, and the accumulation of multiple errors will cause a great deviation between the actual length of the wire and the simulated length by the software, losing the meaning of wire length calculation, and thus unable to ensure the prefabrication effect of the secondary wire.

[0035] Based on the above problems, the embodiment of the present application proposes a method for determining the wire length. By obtaining the target drawing, according to the path information of each group of wire harnesses, determining the straight-line lengths of the wires in each group of wire harnesses, and according to the target drawing, determining at least one node in the target drawing, the type of each node, at least one target wire harness passing through each node, and the relative position of each target wire harness at the node. Thus, according to at least one node in the target drawing, the type of each node, at least one target wire harness passing through each node, and the relative position of each target wire harness at the node, the turning lengths of the wires in each group of wire harnesses can be determined. And by calculating the sum of the straight-line lengths of the wires in each group of wire harnesses and the turning lengths of the wires in each group of wire harnesses respectively, the wire lengths of the wires in each group of wire harnesses are obtained, and the wire lengths of the wires in the target drawing can be accurately determined, thereby ensuring the prefabrication effect of the secondary wire and realizing the unity of the simulated wire length and the actual installation wire length on site.

[0036] First, the application scenario involved in the method for determining the wire length provided by the embodiment of the present application will be described in detail.

[0037] It can be understood that the method for determining the wire length provided by the embodiment of the present application can be deployed in the wire harness drawing software. The user interacts with the wire harness drawing software to realize the layout and drawing of the components and secondary wires in the electrical panel cabinet. After the user finishes drawing the secondary wires and obtains the target drawing, the wire harness drawing software can execute the steps of the method for determining the wire length provided by the embodiment of the present application, obtain the wire lengths of the wires in each group of wire harnesses, and output the wire lengths of the wires in each group of wire harnesses to the user, so that the offline work of the secondary wires can be carried out based on the wire lengths of the wires in each group of wire harnesses. Thus, the user only needs to simply tie the wires of each wire harness with a cable tie after the wires of each wire harness are processed. Among them, the secondary wire refers to the loop composed of electrical equipment used to control and monitor the primary circuit in the power system.

[0038] The following will describe in detail the method for determining the wire length provided by the present application in combination with multiple embodiments.

[0039] Figure 1It is a schematic flowchart of a method for determining the wire length provided by an embodiment of this application. Referring to Figure 1 as shown, the execution subject of this method can be any electronic device with processing capabilities, such as an electronic device deployed with the above-mentioned wiring harness drawing software. This method includes:

[0040] S101. Obtain a target drawing.

[0041] Optionally, the target drawing can be an electrical secondary wiring diagram, that is, a low-voltage circuit diagram used to control, detect, protect, and measure the normal operation of electricity. Among them, the target drawing includes multiple groups of wire harnesses composed of secondary wires, and each wire harness includes at least one wire. The target drawing may also include multiple components.

[0042] Optionally, each wire harness has attributes such as path information and quantity information. Among them, the path information is used to indicate the positions through which each wire harness is routed in the electrical circuit, and the quantity information is used to indicate the number of wires included in each wire harness.

[0043] Optionally, a coordinate file corresponding to the target drawing can also be obtained, and the path information of each wire harness in the target drawing can be determined through the coordinate values of each pixel point in the target drawing in the coordinate file.

[0044] S102. Determine the straight-line length of each wire in each group of wire harnesses according to the path information of each group of wire harnesses.

[0045] Optionally, after obtaining the target drawing, the straight-line length of each wire in each group of wire harnesses can be determined according to the path information of each group of wire harnesses in the target drawing. Among them, the straight-line length refers to the length generated when each wire in each group of wire harnesses is routed in the horizontal or vertical direction.

[0046] Exemplarily, the straight-line length of each group of wire harnesses can be calculated and determined according to the coordinate information of each group of wire harnesses in the target drawing, and the straight-line length of each group of wire harnesses can be used as the straight-line length of each wire in each group of wire harnesses.

[0047] S103. Determine at least one node in the target drawing, the type of each node, at least one target wire harness passing through each node, and the relative position of each target wire harness at the node according to the target drawing.

[0048] Optionally, the path information of each group of wire harnesses in the target drawing can be identified and matched to determine at least one node in the target drawing, and according to the path information of each group of wire harnesses in the target drawing, the type of each node, at least one target wire harness passing through each node, and the relative position of each target wire harness at the node can be determined.

[0049] Optionally, the path information of each group of wire harnesses in the target drawing can also be identified and matched, so as to determine at least one intersection point in the target drawing, and the number of wire harnesses passing through each intersection point is screened according to a preset quantity threshold. When the number of wire harnesses passing through each intersection point exceeds the preset quantity threshold, each intersection point is used as each node, and according to the path information of each group of wire harnesses in the target drawing, the type of each node, at least one target wire harness passing through each node, and the relative position of each target wire harness at the node are determined.

[0050] Among them, each node is respectively the intersection point of multiple groups of wire harnesses in the target drawing, that is, the bundling point of each group of wire harnesses. The type of each node is used to indicate the direction of the wire harness passing through the node. At least one target wire harness passing through each node is the group of target wire harnesses constituting the node. The relative position of each target wire harness at the node is used to indicate the relative position relationship of each target wire harness at the node. For example: being located at the innermost or outermost side.

[0051] Exemplarily, according to the coordinate information in the path information of each group of wire harnesses, the coordinate information of each group of wire harnesses can be matched. When the coordinate information of two or more groups of wire harnesses at a certain point is less than a preset threshold, it can be considered that these two or more groups of wire harnesses intersect, and the intersection point is the intersection. These two or more groups of wire harnesses are used as at least one target wire harness passing through the node, and according to the magnitude of the coordinate information of each group of target wire harnesses at the intersection, the relative position of each target wire harness at the node is determined.

[0052] Exemplarily, Figure 2 is a partial schematic diagram of a target drawing provided by an embodiment of the present application.

[0064] Exemplarily, continue to refer to Figure 2As shown, taking node W1 and node W2 as examples, the path type between nodes W1 and W2 can be determined as the main path based on the path information of wire harness 1, wire harness 2, and wire harness 3 near nodes W1 and W2. And wire harness 1, wire harness 2, and wire harness 3 all have paths with a path type of branch path at node W1.

Thus, on the basis of the turning length of wire harness 1, multiplying by the turning coefficient corresponding to the turning radius of each wire, the turning length of each wire in wire harness 1 is obtained.

[0066] S105. Calculate the sum of the straight lengths of each wire in each group of wire harnesses and the turning lengths of each wire in each group of wire harnesses respectively, and use it as the wire length of each wire in each group of wire harnesses.

By calculating the sum of the straight-line lengths of the conductors in each group of wire harnesses and the turning lengths of the conductors in each group of wire harnesses respectively, the conductor lengths of the conductors in each group of wire harnesses are obtained, and the lengths of the conductors in the target drawing can be accurately determined, reducing the line length calculation error caused by the large number of conductors, thus ensuring the prefabrication effect of the secondary conductors, realizing the unity of the simulated line length and the actual on-site installation line length, reducing the dependence on manual operation in the secondary conductor prefabrication process, reducing the labor cost, and reducing the errors and losses caused by human factors, improving the production efficiency, production quality and intelligent level of the secondary conductor prefabrication process.

[0070] In a possible implementation manner, Figure 3 This is a schematic flowchart for determining the turning lengths of the conductors in each group of wire harnesses in the conductor length determination method provided by the embodiment of the present application. Refer to Figure 3 As shown, the above S104 determines the turning lengths of the conductors in each group of wire harnesses according to at least one node in the target drawing, the type of each node, at least one target wire harness passing through each node, and the relative position of each target wire harness at the node, including:

[0071] S301. Traverse each node in the target drawing. For the currently traversed node, determine the turning lengths of the target wire harnesses passing through the current node at the current node according to the type of the current node, at least one target wire harness passing through the current node, and the relative position of each target wire harness at the current node, and determine the turning lengths of the conductors in each target wire harness at the current node according to the turning lengths of the target wire harnesses at the current node.

[0072] Optionally, when determining the turning lengths of the conductors in each group of wire harnesses, a traversal method can be adopted to traverse each node and respectively determine the turning lengths of the target wire harnesses passing through the current node at the current node.

[0073] Optionally, after obtaining the turning lengths of the target wire harnesses at the current node, the turning lengths of the conductors in each target wire harness at the current node can be determined according to the turning lengths of the target wire harnesses at the current node in combination with the number of conductors in each target wire harness.

[0074] Exemplarily, continue to refer to Figure 2As shown, a traversal method can be adopted to traverse nodes W1, W2, W3, and W4, and respectively determine the turning lengths of wire harness 1 at node W1, the turning length of wire harness 3 at node W1, the turning length of wire harness 1 at node W2, the turning length of wire harness 2 at node W2, the turning length of wire harness 3 at node W2, the turning length of wire harness 1 at node W3, the turning length of wire harness 2 at node W3, the turning length of wire harness 3 at node W3, the turning length of wire harness 4 at node W3, the turning length of wire harness 5 at node W3, and the turning length of wire harness 5 at node W4. Then, based on the turning lengths of each target wire harness at each node, determine the turning lengths of each wire in each target wire harness.

[0075] Exemplarily, continue to refer to Figure 2 As shown, after obtaining the turning length of wire harness 1 at node W1, the turning length of wire harness 1 at node W1 can be used as the turning length of each wire in wire harness 1 at node W1. Alternatively, based on the turning length of wire harness 1 at node W1, and according to the number of wires in wire harness 1, determine the different positions of each wire in the wire harness, and multiply by different turning coefficients according to the different positions, so as to obtain the turning length of each wire in wire harness 1 at node W1.

[0076] S302. After traversing all nodes in the target drawing, based on the turning lengths of each wire in each target wire harness at each node, determine the turning lengths of each wire in each target wire harness.

[0077] Optionally, after traversing all nodes in the target drawing, the turning lengths of each wire in each target wire harness at each node can be obtained, and the turning lengths of each wire in each target wire harness at each node can be accumulated respectively, so as to obtain the turning lengths of each wire in each target wire harness.

[0078] By traversing all nodes in the target drawing, determining the turning lengths of each target wire harness passing through the current node at the current node, and based on the turning lengths of each target wire harness at the current node, determining the turning lengths of each wire in each target wire harness at the current node. After traversing all nodes in the target drawing, based on the turning lengths of each wire in each target wire harness at each node, determining the turning lengths of each wire in each target wire harness can ensure the accuracy of the turning lengths of each wire in the obtained target drawing, thereby ensuring the accuracy of the lengths of each wire in the target drawing.

[0079] In a possible implementation manner, taking the case where the type of the current node is a two-way type as an example, the specific processing procedure for determining the turning length of each target wire harness passing through the current node at the current node is described. When determining the turning length of each target wire harness passing through the current node according to the type of the current node, at least one target wire harness passing through the current node, and the relative positions of the target wire harnesses at the current node in the above S301, it includes:

[0129] Among them, the second target wire harness is any one of the target wire harnesses. Each strongly correlated wire harness is a target wire harness whose path is exactly the same as that of the second target wire harness at the current node. Each weakly correlated wire harness is a target wire harness whose path is not exactly the same as that of the second target wire harness at the current node.

[0140] S504. Determine the turning length of the second target wire harness at the current node according to the first turning length and the second turning length.

[0141] Optionally, half of the first turning length can be summed with half of the second turning length to obtain the turning length of the second target wire harness at the current node.

Also, the first turning length and the second turning length of the second target wire harness at the current node are respectively determined, thereby determining the turning length of the second target wire harness at the current node. This can accurately determine the turning lengths of the wires in the target drawing, avoid turning length errors caused by wire harness shunting or confluence, and thus ensure the prefabrication effect of the secondary wires.
