[0002] With the rapid development of the economy and society and the continuous acceleration of urbanization, the demand for transportation has also increased accordingly. Rail transit, with its significant characteristics of large capacity and high efficiency, plays an important role in the urban transportation system. The power supply system is an important link to ensure the safe operation of rail transit systems such as subways. At present, in urban rail transit projects, in order to meet the construction and installation requirements of the construction unit, it is necessary to draw the laying path of all connecting cables in the power supply system, the laying position on the cable bracket and other information into the AUTOCAD drawing. However, in urban rail transit projects, there are many substations, and the number and types of cable connections are various, which leads to a large workload for substation cable laying drawing. The traditional manual drawing method not only consumes a lot of human resources, has low work efficiency, and is prone to errors, affecting the progress and quality of the project. With the development of urban rail transit projects, traditional manual drawing can no longer meet the needs, and some auxiliary drawing software has been developed. At present, AUTOCAD secondary development technology has been developed for many years, and some electrical professional AUTOCAD drawing design software has been available on the market. However, due to the particularity of urban rail transit application scenarios and design requirements, the existing software cannot be directly applied. Therefore, it is necessary to develop an intelligent design software for cable laying in the rail transit field to improve design efficiency, ensure design quality, and better serve construction.

[0054] The following is an example of an intelligent design method for cable laying in a rail transit substation provided by the present application.

[0055] Embodiment 1:

[0056] like Figure 1 As shown, using the above system, an embodiment of the present invention provides a schematic flow chart of an intelligent design method for cable laying in a rail transit substation, which specifically includes the following steps:

[0057] S1: Import cable list: import the external cable list into AUTOCAD through calling, automatically read the key information of each cable to be drawn and save it in the internal database of the software to obtain the cable details;

[0058] S2: Cable laying plan drawing: Load the AUTOCAD file for cable laying and make preparations before cable laying, including setting the trunk path, setting the equipment nodes, setting the bracket points and setting the trunk path parameters, converting the text of the equipment number in AUTOCAD into an attribute block with coordinate positioning, and automatically traversing all feasible laying paths based on the read cable list information and the established path laying model, and determining the final laying path according to the set target path function, completing the automatic laying path design and drawing of each cable. Specifically including the following steps:

[0059] S21: Prepare in advance the AUTOCAD file of the substation layout plan for drawing the cable laying plan. The installation position design of the main equipment has been completed in the drawing, and the main path of cable laying is drawn in the AUTOCAD drawing. The function of the cable laying main path is to constrain the path that each cable can be laid and pass, which can be understood as a "highway". When designing the cable laying path in the software, it is necessary to design along the main path;

[0060] S22: setting trunk path parameters in the software, including the cable support form, support layer number, support arm length, etc. on the trunk path, as well as the type and number of cables allowed to be laid on each layer of the cable support arm;

[0061] S23: setting global parameters on the software interactive interface, including display color, line width, cable bracket spacing, cable length adjustment coefficient, cable model number, etc. in the AUTOCAD drawing;

[0062] S24: Convert the text of the equipment number in the AUTOCAD drawing into an attribute block with coordinate positioning; the software first identifies all the text representing the equipment number in the AUTOCAD drawing, extracts the equipment number from the identified text, and obtains its coordinates in the drawing, creates an attribute block for each equipment number, and adds number attributes and coordinate attributes to the attribute block, that is, replaces the original text object with an attribute block with number and coordinate attributes. The attribute block is a special block that contains not only graphic information but also attribute data that can be edited and queried, so that the software can automatically read and process the equipment information.

[0063] S25: Set the section card points. According to the key nodes of the cable laying path, determine the locations where the section card points need to be set and create the section card points. These locations usually include the starting and ending positions of the cable laying, the turning points of the cable path, the connection points of important equipment, etc. Use the commands or tools in the AUTOCAD software to draw the card point symbols and place them in the correct position. For ease of management and tracking, set a unique number for each section card point. Set the number of the first card point, for example 1-1, the software will automatically increase the card point number according to the preset rules, for example, the next card point number is 2-2, the next one is 3-3, and so on.

[0064] S26: The software automatically generates a cable laying path, based on the read cable information and the set parameter information, automatically completes the cable path laying along the drawn trunk path according to the established laying model. Specifically,

[0065] 1) When laying cables in software, the cable information is read line by line by reading the imported "cable list" to obtain the name and number of the starting device (sub-device), the name and number of the end device (sub-device), the cable type, the cable specification model, the number of cables and other parameters of the cable;

[0066] 2) In the AUTOCAD drawing, determine the coordinates of the cable start and end points by looking up the positioning attribute blocks of the start point device number and the end point device number;

[0067] 3) Draw a perpendicular line from the starting point coordinates and the end point coordinates to the nearest cable laying trunk path to determine the starting point and end point positions on the trunk path;

[0068] 4) Traverse all laying paths that can reach the end point along the pre-drawn cable laying trunk path according to the laying model along the starting point, calculate and record the cable laying length on various possible paths; when passing through a path intersection in the trunk path, such as a junction, determine whether the next path can be passed according to the laying model. The laying model mainly has two items. When both laying models are satisfied, the next path can be passed, as follows:

[0069] The first laying model is to determine whether the cable support on the next section of the path can continue to withstand the installation conditions of this loop of cable. According to the type of this loop cable, the arm layer on the next section of the path where this type of cable is allowed to be laid, and the number of cables of this type on the current arm layer, it is determined whether the number of cables of this type after the current cable continues to be laid on the arm layer exceeds the total number limit constrained when the trunk path is set. If it exceeds, it does not meet the requirements and is not allowed to pass. For example, the type of this loop cable is AC medium voltage cable, and the number of cables is 3. At the intersection, there are two directions in which the laying can continue. The software will then verify the arm layers where the AC medium-voltage cables are allowed to be laid on the next two paths. If, according to the setting of main path 1, the AC medium-voltage cables are allowed to be laid on the 3rd and 4th layers of the arm, with a maximum of 3 cables allowed on each layer, and there are already 3 medium-voltage AC cables on the 3rd layer arm, and no cables on the 4th layer arm, then the cables in this loop in main path 1 are allowed to pass, and the 3 AC medium-voltage cables in this loop are laid on the 4th layer arm; if, according to the setting of main path 2, the AC medium-voltage cables are allowed to be laid on the 4th layer of the arm, with a maximum of 3 cables allowed on each layer, and there are already 3 medium-voltage AC cables on the 4th layer arm, then the cables in this loop in main path 2 do not meet the requirements and are not allowed to pass.

[0070] The second laying model is the installation requirement of whether the main and backup cables can be laid on the same support arm. According to the requirements of relevant design specifications, as an important power load of the first-level load, it is necessary to have two main and backup cables to ensure its power supply reliability, and the specifications require that the main and backup cables must be laid along different paths, and it is not allowed to be laid simultaneously on the same layer of the support arm of the same cable bracket on the laying path. Therefore, a column of imported information "Remarks" is added to the "Cable Details List" designed by the present invention, and "Main" and "Backup" can be filled in the Remarks to identify the two adjacent cables as the main and backup dual-power cables of the same first-level load. When designing the automatic cable laying path, in addition to the cable number restriction requirements in the first laying model at the trunk path point, the software also needs to determine whether there is another cable in the "main" and "backup" of the same first-level load on the cable bracket support arm to be laid on this path. If there is, it does not meet the specification requirements and is not allowed to pass.

[0071] The software automatically determines whether it is possible to pass through the intersection to reach the next section of the path according to the above-mentioned laying model at each intersection of the trunk path, and so on, until it reaches the terminal device location; it infers all feasible laying paths on the trunk path, calculates and records the cable laying length, retains the relevant information of all feasible laying paths, displays it on the interactive interface, and determines the final laying path as the target path function based on the shortest path length, laying difficulty, avoiding specific areas or a combination of factors.

[0072] The calculation steps of the target path function are as follows:

[0073] a. Quantify the factors that affect the laying path and define

[0074] L path is the path length from the starting point to the end point;

[0075] C complexity is the path complexity, which can be a combination of indicators such as the number of turns and the height of ascent and descent;

[0076] A avoidance The cost of avoiding specific areas, such as passing through high temperature areas, flammable areas, etc., can be a Boolean value or a quantified cost;

[0077] Other factors affecting quantification...

[0078] w 1 ,w 2 ,w 3 ,…are the weights of each factor, which need to be adjusted according to the needs of the specific project to reflect their importance in the overall evaluation.

[0079] b. Construct a target path function. Construct a suitable target path function and integrate the quantitative influencing factors into an optimization problem by weighted summation. The target path function F is expressed as:

[0080] F (path) =w 1 ×L path +w 2 ×C complexity +w 3 ×A avoidance +……

[0081] Among them, w 1 ×L path To minimize the path length.

[0082] w 2 ×C complexity To minimize the difficulty or complexity of laying.

[0083] w 3 ×Aavoidance To avoid the impact of specific areas.

[0084] c. Use the above target path function to evaluate each feasible path and select the path that makes F (path) The minimized path is taken as the optimal routing path.

[0085] This target path function allows the software to automatically evaluate and recommend the best cable routing path while ensuring that all design specifications and technical requirements are met. In actual applications, the selection of weights and the setting of penalty values ​​need to be adjusted according to the specific project situation and the specific needs of the user.

[0086] 5) At each section checkpoint passed through in the determined optimal path, record the laying position and number of the cable on the cable support arm on this section of the path to constrain the laying logic of other subsequent cables.

[0087] 6) According to the above logic, the software completes the automatic laying path design and drawing of each cable in the imported cable list in batches, and obtains the laying length of all cables.

[0088] 7) After the automatic drawing is completed, all feasible laying paths for each cable laying can be viewed in the software interactive interface, and the path can be manually verified or modified. After the modification, the laying information of the cable is reset to obtain the modified cable laying diagram.

[0089] S3: Drawing of cable laying profile: After the laying path is confirmed, the software automatically generates a cable laying profile according to the built-in cable support profile drawing rules and programming commands, and inserts the real-time profile of each cable laying profile card point into the AUTOCAD drawing. Among them, the cable support type and number of layers in the profile are automatically drawn according to the parameters set when the trunk path is set, and the cable number in the profile is drawn according to the recorded data at the card point when the above-mentioned automatic path is laid. Specifically, it includes the following specific steps:

[0090] S31: Preset drawing rules for cable support profiles, which can be automatically combined according to the set number of layers, installation form, and support form. For example, the number of layers is automatically stacked up, and 4 layers, 5 layers or any number of layers are all possible.

[0091] S32: extracting the cable number and related information at each checkpoint from the cable laying path, including the cable type, the starting device number, and the ending device number, and extracting the cable support type and layer number parameters set when setting up the trunk path.

[0092] S33: The software first identifies all key checkpoints along the cable path through built-in programming commands, and then based on the specific conditions of the checkpoints, automatically fills in and annotates the specific configuration of the cable rack and the number of each cable according to the drawing rules of the cable rack profile and the extracted information, and automatically generates a cable laying profile diagram, that is, inserting the real-time profile diagram of each cable laying profile checkpoint into the AUTOCAD drawing.

[0093] S4: Automatically generate cable list and cable engineering quantity table: Based on the imported cable information and the completed cable laying design, automatically identify the selected laying path, calculate the length of each cable, automatically generate a cable list, classify and count the cable engineering quantity according to the built-in programming logic, form a complete cable material list, and export the final version of the cable list and cable engineering quantity table to Excel or other file formats that are easy to share and edit, to complete the design of the optimal cable laying path. Specifically,

[0094] 1) Automatically generate cable list: The automatically generated cable list is basically the same as the "cable list" pre-imported before drawing the software, including cable number, type, specification, length, start position and end position, etc. The design software will further process it, including:

[0095] ① The cable number is combined according to the cable type, cable starting device number, and cable end device number in the imported "cable list". According to the predefined rules, a unique number is generated for each cable, for example, in the form of "AB / C" according to the design drawing principle;

[0096] ② The length of each cable is calculated and counted according to the laying path automatically identified and selected by the software in AUTOCAD, and automatically filled into the corresponding "length" column. The cable length takes into account the certain margin requirements in the actual engineering installation. The length of each cable laying is extracted by extracting the AUTOCAD polyline length of the laying path. The "starting end cabinet length" and "adjustment coefficient" are set in the global parameters. The cable measurement length = (actual cable length + starting end cabinet length × 2) × adjustment coefficient × number of cables;

[0097] 2) Automatically generate a cable engineering quantity table: Based on each cable type, cable specification model, number of cables, etc., the built-in programming commands are used to sum up the individual data and automatically generate a cable engineering quantity table. Specifically:

[0098] The number of cables is summed up according to the cable lengths in the generated cable list;

[0099] The number of cable terminal heads is calculated by multiplying the number of cables in the generated cable list by 2 and then summing them up by category.

[0100] The number of cable brackets is the trunk path length / bracket placement spacing in the global parameters in AUTOCAD, and then the classification and summation;

[0101] The number of cable bracket anchor bolts is the number of anchor bolts of each type of cable bracket multiplied by the number of cable brackets when setting the trunk path, and then summed.

[0102] Embodiment 2: The following is another embodiment to illustrate a rail transit substation cable laying intelligent design method provided by the present application. The method includes the following processing steps:

[0103] Step 1: In AUTOCAD, load the cable laying plug-in through the "Load Command", click the "Import Cable List" menu on the main interface, and select the cable list parameter file to be loaded. After the loading is successful, the corresponding data will be displayed on the interface. Figure 2 Shown

[0104] Step 2: Complete the laying path design according to the steps described in Example 1, such as Figure 3 As shown in the figure, the relevant information of all feasible laying paths is retained and displayed on the interactive interface, and the laying path is determined with the shortest laying length path as the target path, completing the drawing of the cable laying plan and cross-section diagram. Figure 4 and Figure 5 They are respectively schematic diagrams of a cable laying plan view and a cable laying cross-sectional view according to an embodiment of the present invention.

[0105] Step 3: After the automatic drawing is completed, all feasible laying paths for each cable laying are checked in the software interactive interface, and the paths are manually verified or modified. After the modification, the laying information of the cable is reset.

[0106] Step 4: After completing the drawing of the cable laying plan and cross-section, automatically complete the cable details and engineering quantity statistics and output them.

[0107] The design method proposed in the present invention realizes the definition of the cable starting point, end point, cable specifications, number of cables and other information by importing a cable inventory table in a software interface; realizes automatic identification of the cable starting point and end point positions by converting the equipment name text into an attribute block with coordinates in the AUTOCAD plan layout diagram; realizes automatic planning of the cable laying path and automatic design of the laying position of the profile diagram by setting the cable laying trunk path and setting the laying model; and realizes automatic statistics of the cable length and the cable laying engineering quantity through software data recording, thereby simplifying the design process, greatly reducing the drawing workload, and greatly improving the design efficiency and quality.

[0108] Embodiment 3:

[0109] An embodiment of the present invention provides an intelligent design system for cable laying in a rail transit substation, which is applied to implement the steps of the above-mentioned intelligent design method for cable laying in a rail transit substation, including a cable list importing function module, an automatic cable laying function module and an automatic statistical table generation function module.

[0110] Cable list import function module: import external substation cable information through AUTOCAD call and save it in the internal database of the software. After importing into the software, the software can read key information such as the starting point and end point equipment number of each cable to be drawn. At the same time, while reading the data, the software can perform preliminary error correction by comparing the name and number. For example, when the same device name corresponds to different device numbers or the same device number corresponds to different device names, prompts can be given in the software interactive interface. Ensure that the substation cable information can be accurately loaded into the software to provide basic data support for subsequent cable laying design. The cable list includes cable type, starting device name, starting device number (including sub-device name and number), end device name, end device number (including sub-device name and number), cable specification model, number of cables and units, etc.

[0111] Automatic cable laying function module: It is the core part of the whole system.
