Description

Technical Field

[0001] This invention relates to the field of substation electrical secondary system design technology, specifically to a method for assembling four-core cables on both sides based on substation secondary design. Background Technology

[0002] Currently, electrical designers typically use manual terminal wiring diagrams in CAD when designing secondary electrical circuits. This method is problematic because it requires manual verification of the consistency between the schematic diagram and the terminal block diagram. Furthermore, when connecting cables to terminal blocks on both sides, especially when the cable start and end points are in different volumes, repeated manual reference and comparison are necessary. These operations are not only time-consuming but also prone to errors, frequently leading to design changes. Related technologies include using single-core wires on both sides, which requires a single schematic diagram to fully represent the terminal and core wire data on both sides. The terminal block diagram references the schematic data to generate the terminal block cable, but this method suffers from problems such as needing to change drawing habits and output styles, and the inability to create and modify data only within the schematic diagram, resulting in poor flexibility.

[0003] PIN point: refers to the connection point of a terminal. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a method for intelligent design and implementation of electrical secondary circuits based on four-core wires on both sides, thereby realizing intelligent design of electrical secondary circuits and saving on schematic diagrams and terminal blocks. Figure 1 The manual verification of consistency and cable uniformity on both sides improves design efficiency and quality. The four-core cable approach on both sides allows data to be created and modified on either side, while the other side can reference and connect it. The design method is free and flexible, which is more in line with the traditional design habits of designers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A method for assembling four-core cables on both sides based on the secondary design of a substation provides a system including a drafting terminal and a database. The drafting terminal and the database set four-core cables on both sides for any electrical circuit, namely the starting side and the ending side of the electrical circuit. The four core cables refer to the schematic core cable on the starting side, the terminal block core cable on the starting side, the schematic core cable on the ending side, and the terminal block core cable on the ending side, respectively. Driven by database rules, schematic core cables and terminal block core cables on the same side are created by mutual copying through the same connected terminals. Core cables on different sides are grouped into the same cable and connected by the same circuit number and circuit function.

[0006] Furthermore, the database rule-driven approach allows for the creation of schematic core wires and terminal block core wires on the same side through mutual copying based on the same connected terminals. Specifically, the drafting end creates schematic terminal and terminal block terminal models with information attributes using drafting software and stores these models in the server-side database. By using terminals with the same name, a connection is established between schematic terminals and terminal block terminals. When a schematic core wire is drawn from a schematic terminal, the terminal block terminal automatically links the attributes of the core wire connected to the schematic terminal with the same name, drawing a terminal block core wire with the same attributes. For terminal blocks without a schematic, the core wire is directly inserted into the terminal block.

[0007] Furthermore, the connection of different side core wires to the same cable through the same circuit number and circuit function is specifically as follows: Select the schematic core wire or terminal block core wire of the cable to be connected on the drawing software drawing, traverse and search the database to find all cables and their core wires that open to this cabinet, and use the cables with the same core wire circuit function to design the cable connection and its connection. When the database does not have a cable with the same core wire circuit function after traversal and search, specify the side cabinet of the core wire, enter the cable connection number, create a new cable and submit it to the database.

[0008] Furthermore, the step of creating schematic terminal and terminal block terminal diagram models with information attributes through the drafting end includes: (1) Define the installation unit with a rectangular or polygonal frame, draw the installation unit range frame in the drawing software, and enclose the schematic diagram or terminal block diagram representing the secondary equipment within the range frame. Through terminal and terminal block identification technology, generate terminal diagram data belonging to the installation unit and store it in the server database. (2) Identify the schematic terminal, select the terminal legend and name of a single terminal or a batch of terminals, identify the legend and the terminal name closest to the legend, delete the original legend and terminal name on the drawing software, draw the new legend and terminal name in the original position, and generate schematic terminal pattern data; (3) Identify the terminal block terminals, pick up the terminal block name and terminal number information respectively, measure the width of the terminal block, and generate the corresponding terminal block terminal PIN point pattern data on both sides of the terminal block; (4) Define a terminal block with several pin points; (5) A terminal on the drawing software has a unique identifier ID in the server database. A terminal identifier ID in the server database corresponds to one or more handles of the terminal on the drawing software.

[0009] Furthermore, the specific steps for drawing the schematic diagram core wires and terminal block core wires are as follows: (1) The handle of the core wire on the drawing software surface corresponds one-to-one with the identity ID of the core wire in the database. When the drawing is submitted to the database, it needs to be compared with the data in the database of the drawing. If the core wire ID exists in the database, but the corresponding core wire handle does not exist on the drawing software surface, delete the core wire ID in the database. If the core wire ID in the database is not found through the core wire handle on the drawing software surface, add a core wire ID in the database. If the core wire ID in the database is found through the core wire handle on the drawing software surface, and the core wire is not cabled, update the core wire. If the core wire is cabled, and the attributes of the core wire on the drawing software surface (both the local and opposite cabinets) correspond to the attributes of the core wire ID on the local and opposite cabinets in the database, update the core wire. If the attributes of the core wire on the drawing software surface (both the local and opposite cabinets) do not correspond to the attributes of the core wire ID on the local and opposite cabinets in the database, throw an exception and refuse to submit. (2) Only one core wire handle can be connected to the same PIN point of the same schematic terminal or terminal block terminal in the same cabinet. When multiple core wire handles are connected, an exception is required when checking and uploading to the database, and the upload is rejected. (3) The core wires drawn have a start and end point. The end connected to the terminal on this side is the start point, and the end suspended is the end point. When the end point of the core wire is connected to the terminal on the opposite side, it only indicates that the core wire is connected to the terminal on the opposite side. The core wire still belongs to the core wire of this side, and the opposite side does not have the core wire. (4) When selecting to submit the core line to the database, only the core line attributes of the drawing software are updated to the core line ID and the new core line ID are added to the database. The core line IDs in the database are not deleted. (5) The core wire side cabinets and the side cabinets cannot be the same panel cabinet.

[0010] Furthermore, the cable assembly and connection design specifically includes: (1) Cables can only be assembled after the local and opposite side screen cabinets of the core wires are specified; (2) Enter the cable number to assemble the cable. The database must be traversed to search for the cable with this number and the uniqueness of the cable number must be verified. (3) All core wires used for cable assembly must be unassembled core wires. If there are already assembled core wires, they must be removed from the cable assembly first. (4) The core wire connection design can only be completed after the cable is assembled. Before the core wire is removed from the cable assembly, the core wire connection design must be cancelled. (5) The core wire collection elements on both sides of a cable are connected one by one through the core wire loop function. When any collection on this side is connected to any collection on the other side, the core wire collection elements of the terminal block on this side are connected to the core wire collection elements of the terminal block on the other side, and the core wire collection elements of the schematic diagram on this side are connected to the core wire collection elements of the schematic diagram on the other side. (6) When designing the core wire connection, it is permissible to use the side on this side or the opposite side as a reference to realize the synchronization of the four core wire loop functions and loop numbers on both sides.

[0011] (7) The core wires of the assembled cable cannot be changed in the cabinet on this side or the cabinet on the opposite side. If changes are required, the assembled cable must be removed. (8) When deleting a cable group, only empty cables without core wires can be deleted; Furthermore, when grouping cables using the input cable numbers, it is necessary to verify the uniqueness of the cable numbers, specifically as follows: (1) If the number exists and there is no core wire under the cable, delete the empty cable and create a new cable with this number; (2) If the number exists and there are core wires under the cable, but the core wires of the two side cabinets are inconsistent with those of the cable to be assembled, confirm that the number will continue to be used, mark "*" on the number to create a new cable, confirm that it will be abandoned, and return to re-enter other cable numbers; (3) If the number exists and there is a core wire under the cable, and the two side cabinets are consistent with the selected core wire, confirm the merging, save the group cable information, perform the fiber core merging logic, confirm the new cable, mark "*" on this number to create a new cable, confirm the abandonment, and return to re-enter other cable numbers; (4) If the number does not exist, a new cable will be constructed using this number; Compared with the prior art, the present invention has the following advantages: This invention eliminates the need for manual comparison of schematic diagrams to terminal blocks and re-insertion of core wires. It adopts a forward design approach, allows for flexible cable assembly, conforms to traditional design habits, and can effectively improve the efficiency and quality of drawing design.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] This invention provides a method for assembling four-core cables on both sides based on the secondary design of a substation. A system is provided, including a drafting terminal and a database. For any electrical circuit, the drafting terminal and the database configure four-core cables on both sides, namely the starting side and the ending side of the circuit. The four core cables refer to the schematic core cable on the starting side, the terminal block core cable on the starting side, the schematic core cable on the ending side, and the terminal block core cable on the ending side. The key feature is that, driven by database rules, schematic core cables and terminal block core cables on the same side are created by mutual replication through identical connected terminals. Core cables on different sides are grouped into the same cable and connected by having the same circuit number and circuit function.

[0016] In this embodiment, preferably, the drafting software used is CAD; refer to Figure 1 In this embodiment, a method for assembling four-core cables on both sides based on the secondary design of a substation is provided, as detailed below: Step S1: Create terminals and establish association between schematic terminals and terminal block terminals: Create schematic terminal and terminal block terminal models with information attributes in the CAD client, and store their information models in the server database. Establish association between schematic terminals and terminal block terminals based on identical terminal names, such as... Figure 2 The information attributes of the schematic terminal include the terminal block name, terminal separator, terminal number, and the cabinet to which it belongs. The cabinet to which it belongs is determined by the cabinet frame in which the terminal is located on the CAD drawing. The information attributes of the terminal block terminal include the terminal block name, terminal separator, terminal number, terminal connection point (PIN point), and the cabinet to which it belongs. The terminal block name and terminal number of the schematic terminal and the terminal block terminal are the same, thus linking the schematic terminal and the terminal block terminal.

[0017] Step S2: Draw schematic core wires and terminal block core wires: Schematic core wires are drawn from schematic terminals by inserting core wires or identifying core wires. Core wires have information attributes: circuit number, local terminal, local terminal connection point, etc. After submitting to the server database, select the terminal block terminal and use automatic core drawing to draw terminal block core wires with the same circuit number, local terminal, and local terminal connection point as the schematic core wires. If the terminal block does not have a corresponding schematic, core wires can be directly inserted at the terminal block terminal connection point, and the circuit number of the core wire can be edited. Step S3, Cable Assembly and Connection Design: Select the core wires from the schematic diagram or terminal block core wires of the cables to be assembled, and start the traversal search method to find all cables and their core wires that extend to this cabinet, such as... Figure 3The process is concentrated on the cable tree on the left side of the cable assembly interface. By comparing the selected core wire with the loop number of the core wire in the cable tree, the software selects the applicable cable and its core wire for cable assembly and completes the core wire connectivity design. If no cable with the same core wire loop function is found after searching, the opposite side cabinet of the core wire needs to be specified, and a new cable number needs to be entered for cable assembly to complete the design on this side. When designing the opposite side, the software will automatically display this cable on the cable tree, directly reference this cable for cable assembly, and complete the core wire connectivity design.

[0018] Preferably, in this embodiment, step S1, creating terminals and establishing the association between schematic terminals and terminal block terminals, further includes: (1) Define the installation unit with a rectangular frame or a polygonal frame, copy the manufacturer's drawing or any drawn drawing to the CAD, select the installation unit, enclose the drawing in the frame with a rectangular frame, generate the terminal pattern data belonging to the installation unit through terminal and terminal block recognition technology, store it in the server database, and represent it as one terminal with two patterns on the CAD drawing: schematic terminal pattern and terminal block terminal pattern; or one terminal with one pattern: only terminal block terminal pattern. (2) Identify the schematic terminal, select the terminal legend and name of a single terminal or a batch of terminals, identify the legend and the terminal name closest to the legend, delete the original legend and terminal name on the CAD drawing, draw the new legend and terminal name in the original position, and generate schematic terminal pattern data; (3) Identify the terminal block terminals, pick up the terminal block name and terminal number information respectively, measure the width of the terminal block, select the left terminal block or right terminal block attribute, generate the corresponding terminal block terminal PIN point pattern data on both sides of the terminal block, one side is outer 1 or outer 2, and the other side is inner 1 or inner 2. (4) Define a terminal to include multiple connection points (PIN points) such as outer 1, outer 2, inner 1, and inner 2.

[0019] (5) A terminal on the drawing software has a unique identifier ID in the server database. A terminal identifier ID in the server database corresponds to one or more handles of the terminal on the drawing software.

[0020] Preferably, in this embodiment, drawing the schematic core wires and terminal block core wires further includes, (1) The handle of the core wire on the CAD drawing corresponds one-to-one with the identification number ID of the core wire in the database. When submitting the drawing to the database, it needs to be compared with the data in the database of that drawing. If the core wire ID exists in the database, but the corresponding core wire handle does not exist on the CAD drawing, the core wire ID in the database is deleted, such as... Figure 4The CAD drawing originally had 11 core wires, corresponding to 11 core wires in the database on the left. After deleting 6 core wires on the CAD drawing and submitting the drawing to the database, 5 core wires remained in the database on the left. If the core wire ID in the database could not be found through the core wire handle on the CAD drawing, a new core wire ID was added to the database. If the core wire ID in the database could be found through the core wire handle on the CAD drawing, and the core wire was not yet cabled, the core wire was updated. If the core wire was already cabled, and the attributes of the core wire in the CAD drawing (either the local cabinet or the opposite cabinet) matched the attributes of the core wire ID in the database (either the local cabinet or the opposite cabinet), the core wire was updated. If the attributes of the core wire in the CAD drawing (either the local cabinet or the opposite cabinet) did not match the attributes of the core wire ID in the database (either the local cabinet or the opposite cabinet), an exception was thrown, and submission was rejected.

[0021] (2) Only one core wire handle can be connected to the same PIN point of the same schematic terminal or terminal block terminal in the same cabinet. When multiple core wire handles are connected, an exception is required when submitting to the database and the upload is rejected. (3) The core wires drawn have a start and end point. The end connected to the terminal on this side is the start point, and the end suspended is the end point. When the end point of the core wire is connected to the terminal on the opposite side, it only indicates that the core wire is connected to the terminal on the opposite side. The core wire still belongs to the core wire of this side, and the opposite side does not have the core wire. (4) When selecting to submit the core wire to the database, only the core wire attributes of the CAD end are updated to the core wire ID in the database and the new core wire ID is added. The core wire ID in the database is not deleted. (5) The cabinet on this side and the cabinet on the opposite side of the core wire cannot be the same panel cabinet.

[0022] Preferably, in this embodiment, the cabling and connectivity design further includes, (1) Cables can only be assembled after the local and opposite side screen cabinets of the core wires are specified; (2) Enter the cable number to assemble the cable. The database needs to be traversed to search for the cable with this number and the uniqueness of the cable number needs to be verified. See the flowchart. Figure 5 .

[0023] a. If the cable number exists and there are no core wires under the cable, delete the empty cable and create a new cable with this number. b. If the number exists and there are core wires under the cable, but the core wires of the two side cabinets are inconsistent with those of the cable to be assembled, confirm that this number will continue to be used, mark "*" on this number to create a new cable, confirm to abandon, and return to re-enter other cable numbers; c. If the number exists and there is a core wire under the cable, and the two side cabinets are consistent with the selected core wire, confirm the merging, save the cable group information, perform the fiber core merging logic, confirm the new cable, mark "*" on this number to create a new cable, confirm the abandonment, and return to re-enter other cable numbers. d. If the number does not exist, a new cable will be constructed using this number; (3) All core wires used in the cable assembly must be unassembled core wires. If there are already assembled core wires, they must be removed before assembling the cable. See [link to relevant documentation]. Figure 5 ; (4) The core wire connection design can only be completed after the cable is assembled. Before the core wire is removed from the cable assembly, the core wire connection design must be cancelled. (5) The core wire collection elements on both sides of a cable are connected one by one through the core wire loop function. When any collection on this side is connected to any collection on the other side, the core wire collection elements of the terminal block on this side are connected to the core wire collection elements of the terminal block on the other side, and the core wire collection elements of the schematic diagram on this side are connected to the core wire collection elements of the schematic diagram on the other side. (6) When designing the core wire connection, it is permissible to use the side on this side or the opposite side as a reference to realize the synchronization of the four core wire loop functions and loop numbers on both sides.

[0024] (7) The core wires of the assembled cable cannot be changed in the cabinet on this side or the cabinet on the opposite side. If changes are required, the assembled cable must be removed. See Figure 5 ; (8) When deleting a cable group, only empty cables without core wires can be deleted; The above description is only a preferred embodiment of the present invention.
