This technology is highly dependent on manual labor, and the quality and efficiency are greatly affected by the subjective factors of personnel, which may affect the operational efficiency of its entire life cycle.

[0003] In the production of power secondary switchgear products, the variety of types and models, the different interface definitions from different manufacturers, the significant differences in electrical wiring, and the high complexity of wiring are all significant challenges. Currently, the wiring of power secondary switchgear products mainly involves constructing a 3D model and then using 3D electrical wiring software to design the wiring based on the 3D model. However, this wiring method needs to handle the wiring problems of multiple components, high density, and multiple constraints in 3D space. The multiple spatial dimensions (needing to consider X / Y / Z axis interference) lead to complex component layouts. It is precisely because of the complexity of spatial wiring that the planned path may conflict with the actual electrical component layout. Summary of the Invention

[0064] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0065] Example 1

[0066] According to relevant technical records, there are numerous types and models of power secondary switchgear, with different manufacturers defining different interface methods and exhibiting significant differences in electrical wiring, resulting in high complexity in electrical wiring during manufacturing. Currently, there are no application cases of automated flexible production of secondary switchgear, either domestically or internationally. Each switchgear requires process breakdown and analysis based on the specific project drawings, thus failing to meet the prerequisite requirement of "product modularization" for automated production.

[0067] Taking a certain type of power secondary cabinet as an example, by decomposing the product BOM, the electrical wiring table of each cabinet involves about 400 electrical wire harnesses of different lengths, wire diameters, and terminal types, which is a huge workload; and it involves more than 50 different sizes, hole diameters, and hole spacings of connectors in different areas such as protection devices, measurement and control devices, circuit breakers, pressure plates, and back plates, which places extremely high demands on the repeatability of wiring, the size of the working space, and the planning of the walking trajectory.

[0068] Currently, the traditional wiring solution for power secondary switchgear products mainly involves building a 3D model and then using 3D electrical wiring software to design the wiring for the 3D model. However, this wiring method needs to deal with the problem of 3D spatial wiring with multiple components, high density and multiple constraints. Due to the multiple spatial dimensions (X / Y / Z axis interference needs to be considered at the same time), the component layout is complicated. It is precisely because of the complexity of spatial wiring that the planned path will conflict with the actual electrical component layout.

[0069] Please refer to Figure 1 , Figure 1 The present invention provides a wiring method for a power secondary switchgear, comprising steps S101 to S105; wherein each step is described in detail below:

[0070] Step S101: Obtain the three-dimensional model of the power secondary cabinet, and determine the components to be plugged in based on the three-dimensional model of the cabinet.

[0071] In this embodiment, existing technologies can be used to perform three-dimensional modeling of the power secondary power cabinet. For example, laser scanning can be used to obtain point cloud data, and the three-dimensional model of the power secondary power cabinet can be obtained based on the point cloud data; or three-dimensional simulation technology can be used to manually perform three-dimensional modeling of the power secondary power cabinet.

[0072] The three-dimensional model of the cabinet can be used to determine the components to be plugged in and their positions.

[0073] Step S102: Determine the first starting point position and the first ending point position of the wire harness according to the component position of the component to be plugged in; and calculate the length of the first wire harness according to the first starting point position and the first ending point position.

[0074] In this embodiment, since this application pertains to wiring in a power secondary cabinet, specifically to the wiring between components to be plugged in, the starting and ending points of the wire harness are often the locations of the components to be plugged in. Therefore, based on the locations of the components to be plugged in, this embodiment can determine the first starting and ending points of the wire harness. Furthermore, based on the first starting and ending points of the wire harness, path planning can be performed, such as using the A* algorithm (also known as the A-star algorithm), to obtain the first wire harness length.

[0075] The A* or A-star algorithm is one of the most fundamental algorithms in path planning, graph search, and artificial intelligence. Its core objective is to find the path with the minimum cost from the starting node A to the destination node B in a graph composed of nodes and edges. Its core idea is to heuristically and directionally expand the nodes with the best chance of reaching the goal, rather than blindly searching. Specifically, given the starting node A and the destination node B, the algorithm breaks down the path to be planned into multiple steps with multiple intermediate nodes, finding the most suitable node as a correction point until the destination node B is reached.

[0076] For example, the step of calculating the length of the first harness based on the first starting position and the first ending position includes: taking the shortest preliminary planned path as the third objective function, and based on the third objective function, solving for a number of third correction points according to the first starting position and the first ending position; wherein, a locking pin is provided within a preset range around each of the third correction points; the first starting position, each of the third correction points and the first ending position are connected sequentially to obtain the preliminary planned path; and the length of the first harness is calculated based on the preliminary planned path.

[0077] In some implementations, the objective of the A* algorithm can be configured as follows:

[0078]

[0079] The constraints of the A* algorithm can be configured as follows:

[0080]

[0081] In the formula, S is the path (length) to be solved between the two insertion points, starting node A and target endpoint B, and v i Let E be the i-th correction point, and the total number of correction points is n. L (v i ) for v i Horizontal error; d(v n-1 ,v n ) is the correction point v n-1 and correction point v n The distance between them, θ is a preset distance threshold, E p (v i ) represents the vertical error. If v i If E is the vertical correction point, then p (v i )=0,E L (v i )=d(v i-1 ,v i If v i If E is the horizontal correction point, then L (v i )=0,E P (v i )=d(v i-1 ,v i If e P (v i )≤α1e L (v i If α ≤ α2, then E p (v i )=0,E L (v i ) = e L (v i If e P (v i )≤β1e L (v i If )≤β2, then E p (v i ) = e P (v i ),E L (v i ) = 0. Where α1, α2, β1, and β2 are pre-set acceptable deviations, and e p (v i ) is the correction point v i The vertical error, e L (v i) is the correction point v i The horizontal error is categorized into two parts: horizontal correction points and vertical correction points. Horizontal correction points are primarily used to correct positional errors in the horizontal plane (i.e., errors in the X and Y axes); vertical correction points are used to correct positional errors in the vertical direction (i.e., errors in the Z axis, which are also known as height errors).

[0082] In this step, by substituting the first starting point position and the first ending point position into the starting node A and the target ending point B respectively, several paths with minimum cost can be obtained as the preliminary planned paths. This cost can refer to the length of the path. Furthermore, based on the obtained preliminary planned paths, the length of the first harness can be estimated or calculated using a preset algorithm.

[0083] Furthermore, the first starting point position, first ending point position, and first wire harness length obtained in this step can be used to generate an electrical wire harness coordinate file for later use. The header information of this electrical wire harness coordinate file can include all the information required for production and processing, such as wire number, wire diameter, wire length, starting point coordinates, ending point coordinates, and N inflection point coordinates.

[0084] It's important to note that the "inflection point" refers to the location of the locking pin. Since wiring harnesses are often not straight, they may have several inflection points. When connecting to the back panel of the control cabinet, locking pins are typically used to secure these inflection points, preventing the harness from becoming loose. It's important to understand that this inflection point is not the same as a calibration point. A calibration point is not an actual point on the back panel of the control cabinet, but rather exists only in the path planning algorithm. The location of the inflection point or locking pin can be obtained from the location of the calibration point, for example, by selecting the nearest inflection point or locking pin to the calibration point.

[0085] Step S103: Configure the component to be plugged into a preset wiring fixture to obtain a planar fixture model; and use the planar fixture model to update the first starting position and the first ending position to obtain the second starting position and the second ending position.

[0086] It should be noted that the first starting point and the first ending point positions mentioned above are only the preliminary starting point and ending point of the wiring harness. When the component to be plugged is configured into the preset wiring fixture in this step, the position of the component to be plugged will change slightly, and the first starting point and the first ending point positions mentioned above will also change accordingly. Therefore, when configuring the component to be plugged into the preset wiring fixture in this step, it is necessary to update the first starting point and the first ending point positions using the obtained planar fixture model to obtain the second starting point and the second ending point positions, so as to solve the path again in subsequent steps.

[0087] like Figure 2 As shown, Figure 2This is a structural schematic diagram of one embodiment of a cabling fixture. It includes a device connector, a cabinet backplate, a backplate connector, a backplate snap-fit ​​module, and snap-fit ​​pins.

[0088] The components to be plugged in according to this invention application are divided into two types: backplane connectors and device connectors. The wiring method of the power secondary cabinet provided by this invention application is mainly aimed at the wiring between device connectors and backplane connectors, as well as the wiring between a backplane connector and another backplane connector.

[0089] This step configures the components to be connected onto a preset wiring fixture to obtain a planar fixture model. The purpose is to transform the complex spatial wiring problem into a relatively planar wiring problem. The fixture can be used to fix the back panel of the cabinet and electrical components, unify the coordinate reference, reduce the interference of a single spatial dimension variable (such as simplifying the X / Y / Z axis to the X / Y axis), avoid the complexity of spatial wiring, and reduce the degree of conflict between the planned connection path and the actual layout of electrical components. It is understood that this planar fixture model can be three-dimensional or two-dimensional. When a three-dimensional model is used, this invention mainly utilizes one of its planes for wiring.

[0090] Step S104: Based on the second starting point position and the second ending point position, plan the connection path of each wire harness; and calculate the length of the second wire harness based on the connection path.

[0091] In some preferred embodiments, the step of planning the connection path of each wire harness based on the second starting position and the second ending position includes:

[0092] The type of the component to be plugged in is determined, including a device connector, a first backplane connector, and a second backplane connector; the device connector is used as the second starting position and the first backplane connector is used as the second ending position to plan the first path of the wiring harness; at the same time, different second backplane connectors are used as the second starting position and the second ending position respectively to plan the second path of the wiring harness; the first path and the second path are determined as the connection path.

[0093] As described above, this invention mainly addresses the wiring between the device connector and the backplane connector, as well as the wiring between the backplane connector and another backplane connector. Therefore, when addressing the wiring between the device connector and the backplane connector, since the hole spacing of the device-side connector is relatively denser than that of the backplane connector, this preferred embodiment uses the device connector side as the second starting point and the first backplane connector side as the second ending point. This can effectively reduce the computational resource consumption of path planning and avoid invalid or conflicting wiring.

[0094] Furthermore, the step of planning the first path of the wiring harness by taking the device connector as the second starting point and the first backplate connector as the second ending point includes: taking the shortest first path as the first objective function; based on the first objective function, solving for a number of first correction points by taking the device connector as the second starting point and the first backplate connector as the second ending point; wherein, a locking pin is provided within a preset range around each correction point; and the second starting point, each first correction point, and the second ending point are connected sequentially to obtain the first path.

[0095] The step of planning the second path of the wiring harness by taking different second backplane connectors as the second starting point and the second ending point respectively includes: taking the shortest second path as the second objective function; based on the second objective function, taking different second backplane connectors as the second starting point and the second ending point respectively, and solving to obtain a number of second correction points; wherein, a locking pin is provided within a preset range around each second correction point; and the second starting point, each second correction point and the second ending point are connected sequentially to obtain the second path.

[0096] In this preferred embodiment, the second starting point position and the second ending point position can be substituted into the path from the starting node A to the target ending point B, and the A* algorithm (as described in formulas (1) and (2) above) can be used to solve for several paths with the minimum cost, thereby obtaining the first path and the second path, i.e., the connection path mentioned above. Then, the length of the second harness can be calculated through the connection path. However, it should be noted that since this step is for planar wiring, the Z-axis information does not need to be considered during the path planning process.

[0097] Step S105: Determine the relationship between the length of the first wire harness and the length of the second wire harness; when the length of the first wire harness is greater than the length of the second wire harness, perform wiring on the back panel of the power secondary cabinet according to the connection path of each wire harness and the length of the first wire harness; when the length of the first wire harness is less than or equal to the length of the second wire harness, perform wiring on the back panel of the power secondary cabinet according to the connection path of each wire harness and the length of the second wire harness.

[0098] In this step, by determining the relationship between the length of the first wire harness and the length of the second wire harness, and using the larger of the two for wiring, it can be ensured that the final wire harness length used for wiring has a certain redundancy, avoiding the problem of insufficient length.

[0099] Preferably, the step of wiring the backplane of the power secondary cabinet according to the connection path of each wire harness and the length of the first wire harness includes: generating a first electrical wire harness coordinate file according to the connection path of each wire harness and the length of the first wire harness; the first electrical wire harness coordinate file includes a first wire harness table; sending the first electrical wire harness coordinate file to the wiring robot so that the interface program of the wiring robot can interface with the first wire harness table, thereby realizing the wiring of the backplane of the power secondary cabinet.

[0100] The step of wiring the backplane of the power secondary cabinet according to the connection path of each wire harness and the length of the second wire harness includes: generating a second electrical wire harness coordinate file according to the connection path of each wire harness and the length of the second wire harness; the second electrical wire harness coordinate file includes a second wire harness table; sending the second electrical wire harness coordinate file to the wiring robot so that the interface program of the wiring robot can interface with the second wire harness table, thereby realizing the wiring of the backplane of the power secondary cabinet.

[0101] Furthermore, given the connection path, the nearest inflection point is determined based on the correction point of the connection path, thereby generating a first electrical harness coordinate file and a second electrical harness coordinate file by combining the first harness length and the second harness length.

[0102] The header information of both the first and second electrical harness coordinate files can include all the information required for production and processing, such as wire number, wire diameter, wire length (length of the first harness and length of the second harness), starting point coordinates, ending point coordinates, and coordinates of N inflection points.

[0103] This preferred embodiment can employ an automated wiring robot or robotic arm, which interfaces with the first and second wiring harness tables via an interface program, eliminating the need for secondary manual processing and achieving seamless integration of wiring planning and automated execution. In this embodiment, the proportion of manual intervention in wiring can be controlled below 5%. Wiring using the aforementioned algorithm effectively saves time spent on manual searching and verification of wiring harness connections, improving production efficiency and reducing changeover time from 10 hours to 2 hours. Furthermore, when the product's electrical wiring harness table or wiring diagram changes, only the changed portions need to be re-simulated, and the corresponding mechanical program needs to be modified, minimizing the workload.

[0104] Accordingly, such as Figure 3 As shown, this invention application also provides a wiring system 300 for a power secondary cabinet, including a component determination module 301, a first wire harness length calculation module 302, an update module 303, a second wire harness length calculation module 304, and a wiring module 305; wherein,

[0105] The component determination module 301 is used to obtain the three-dimensional model of the power secondary cabinet and determine the component to be plugged in based on the three-dimensional model of the cabinet.

[0106] The first wire harness length calculation module 302 is used to determine the first starting point position and the first ending point position of the wire harness according to the component position of the component to be plugged in; and to calculate the first wire harness length according to the first starting point position and the first ending point position.

[0135] Compared with the prior art, this invention application has the following beneficial effects:

[0136] This invention provides a wiring method, system, terminal equipment, and medium for a power secondary cabinet. The invention obtains a three-dimensional model of the cabinet and determines the components to be connected. It calculates the first starting point, first ending point, and first wire harness length. The components to be connected are then configured into a preset wiring fixture, thereby updating the wire harness information to obtain the second starting point and second ending point positions. This transforms the complex spatial wiring problem into a relatively planar wiring problem. The fixture can be used to fix the cabinet back panel and electrical components, unifying the coordinate reference and reducing interference from a spatial dimension variable, thus avoiding the complexity of spatial wiring and reducing the conflict between the planned connection path and the actual electrical component layout. Furthermore, this invention obtains the second starting point and second ending point positions through a planar fixture model and then plans the connection path of the wire harness. Compared with existing spatial wiring schemes, this can effectively improve the accuracy of wiring and is easier to standardize. Moreover, by determining the relationship between the first and second wire harness lengths and using the larger of the two for wiring, a certain redundancy in wire harness length can be ensured, avoiding the problem of insufficient length.
