Description

Technical Field

[0001] The present application relates to the technical field of building electrical engineering modeling, and in particular to a lighting circuit modeling quantity calculation method, system, equipment and medium. Background Art

[0002] In building electrical engineering, the design and construction of lighting systems is a complex and tedious task. Traditional lighting system designs are typically drawn using two-dimensional CAD (Computer-Aided Design) drawings. These drawings depict the lighting system using a "lamp-to-lamp circuit" approach, whereby only one circuit is connected to the power supply for every certain number of lamps. To simplify the drawings, the specific routing of each wire is typically not depicted in detail. Instead, a central annotation is added next to the CAD line segment to indicate the lighting path and lamp connection within that area.

[0003] While this method simplifies the drawings, it still requires manual planning of each wire's specific routing and calculations before actual construction. This is not only time-consuming and labor-intensive, but also prone to errors. Consequently, existing calculations for interval lighting circuit modeling are inefficient. Summary of the Invention

Figure 1 It is a flow chart of lighting circuit modeling and calculation, such as Figure 1 As shown, a lighting circuit modeling and quantity calculation method includes:

[0054] Step S101: Acquire CAD line data and CAD text annotation data on a two-dimensional drawing.

[0055] Step S102: Match each CAD text annotation with a circuit number regular expression to determine the circuit name and circuit number corresponding to each CAD text annotation.

[0056] Step S103: Obtain the total path of the three-dimensional model according to the distance between the CAD line data and the bridge, and the number of loops, wherein the total path includes a number of loops and the paths of the several loops.

[0057] Step S104: Determine the number and position information of each lamp on the total path based on the positional relationship between the insertion point of the lamp and the bridge, and based on the distance between the lamp and the total path.

[0058] Step S105: Based on the number and location information of each lamp on the total path and the shortest path between lamps, starting from the distribution box, connect each lamp with the same label on the same circuit to generate a three-dimensional path and engineering quantity for each lighting circuit.

[0059] In summary, embodiments of the present application provide a lighting circuit modeling and quantity calculation method. This method obtains CAD line data and CAD text annotation data from a two-dimensional drawing. Each CAD text annotation is matched with a circuit number regular expression to determine the circuit name and number corresponding to each CAD text annotation. Based on the distance between the CAD line data and the bridge, as well as the number of circuits, a total path for the three-dimensional model is obtained, where the total path includes multiple circuits and the paths of multiple circuits. Based on the positional relationship between the luminaire insertion point and the bridge, and the distance between the luminaire and the total path, the number and position information of each luminaire on the total path are determined. Based on the number and position information of each luminaire on the total path, the method connects luminaires with the same annotations on the same circuit starting from the distribution box according to the shortest path between luminaires, generating a three-dimensional path and quantity for each lighting circuit. This method enables the simultaneous generation of a three-dimensional model for each circuit and real-time quantity calculation from centrally annotated interval luminaire drawings, saving staff the labor cost of drawing matching, improving the accuracy of automated quantity calculation tasks, and enhancing the efficiency of modeling and quantity calculation. This method addresses the low efficiency of interval luminaire lighting circuit modeling and quantity calculation in related technologies.

[0060] In one embodiment, step S101, obtaining CAD line data and CAD text annotation data on a two-dimensional drawing, specifically includes:

[0061] Receive 2D drawings imported into BIM 3D quantity calculation software;

[0062] According to the calling function command, in response to receiving an instruction from a user to select a CAD line in a drawing, extracting data on the same layer as the CAD line and having a characteristic attribute of a straight line, a polyline, a spline curve, or an arc, thereby obtaining the CAD line data;

[0063] According to the calling function command, in response to receiving the instruction of the user to select annotation data in the drawing, the CAD layer corresponding to the annotation data is picked up, and the data with the characteristic attributes of text and including numbers and letters in the CAD layer is filtered to obtain the CAD text annotation data.

[0064] Alternatively, import the 2D drawings into the BIM 3D quantity calculation software and call the function command (including pmazgdbx). The software command bar will prompt the following in sequence:

[0065] Tip 1: Use the left mouse button to select a distribution box; at this time, the user needs to select a distribution box in the drawing.

[0066] Tip 2: Please select the CAD line (or right-click); at this time, the user needs to select the CAD line in the drawing.

[0067] Tip 3: Select the loop annotation. At this point, you need to select the annotation in the drawing. This selection includes left-clicking or right-clicking the mouse.

[0068] After prompt 2, click CAD line to obtain data on the same layer as the CAD line and with the characteristic attributes of straight line, polyline, spline curve, and arc, which are classified as CAD line data.

[0069] After prompt 3, click Annotation Data to select a CAD layer. The filter feature in this CAD layer is text, and the text content includes numbers and letters. The order can be changed, for example, a combination of numbers + letters or letters + numbers, where the number of letters is within a certain number, and is classified as CAD text annotation data. The number can be 3-6. In this embodiment, the number can be 5.

[0070] Step S101 restricts the extraction to data on the same layer as the selected CAD line and with specific attribute properties (such as lines, polylines, splines, and arcs). This ensures that the extracted line data is associated with the target object, avoids interference from irrelevant line data, and improves data accuracy. By filtering data with text attributes and alphanumeric or alphanumeric content, and limiting the number of letters to between 3 and 6, unnecessary text information is effectively filtered out, ensuring that the extracted text annotation data contains key information such as circuit numbers related to electrical circuits, thereby improving data accuracy.

[0071] Step S102: Match each CAD text annotation with the circuit number regular expression to determine the circuit name and circuit number corresponding to each CAD text annotation. Specifically including:

[0072] Determine the regular expression of the circuit number in the CAD text annotation based on the annotation recognition library;

[0073] Match each CAD text annotation with the circuit number regular expression to obtain the data group that meets the circuit number regular expression in each CAD text annotation. Based on the data group, determine the circuit name and circuit number corresponding to each CAD text annotation.

[0074] Optionally, after prompt 3, click the annotation data. The annotation recognition library will determine whether the annotation data contains consecutive alphanumeric characters or alphanumeric characters. If so, the circuit number regular expression will be obtained. If not, automatic recognition will not be possible, and you will need to enter the regular expression in the Circuit Name column of the Circuit Settings box before proceeding. The annotation recognition library is used to determine the circuit number regular expression in CAD text annotations, including alphanumeric characters. For example, if the annotation data clicked is "N2, N3", it contains letters and numbers, so the regular expression is "N number".

[0075] Match each CAD text annotation in the text annotation data using a circuit number regular expression. Each CAD text annotation matching the regular expression is considered a group of data. Each matching CAD text annotation may contain more than one group of data. The separators between groups of data include "space," "comma," "period," "~," "\," " / ," and "-." This determines the number of groups of numbers and circuit names matching the regular expression in each text annotation. Based on the number of circuits, the number of intervals between lighting fixtures is determined, where the number of intervals between lighting fixtures is a certain number less than the number of circuits. The number of groups of numbers represents the number of circuits in the text annotation. If there are n circuits, each circuit on that path is defined as n-1 lighting fixtures apart. For example, if the circuit number regular expression is "N number" and the CAD text annotation is "N5, N6," "N5, N6," "N5 / N6," or "N5-N6," the text annotation will be recognized as containing two groups of data: circuits N5 and N6, with each circuit separated by one lighting fixture.

[0076] Step S102 determines the loop number regular expression in the CAD text annotation through the annotation recognition library, and then matches each CAD text annotation with the regular expression to ensure accurate identification of the loop number. For example, the annotation data "N2, N3" will be identified as two loops N2 and N3. The number of interval lamp connections is determined according to the number of loops to ensure that the lamp connection method of each loop is reasonable and the load is balanced. For example, if there are n loops, each loop is separated by n-1 lamp connections. The annotation recognition library automatically determines whether the annotation data contains consecutive alphanumeric characters / alphanumeric characters. If so, the loop number regular expression is automatically derived, which reduces manual intervention and improves processing efficiency.

[0077] Step S103: Obtain the total path of the 3D model based on the distance between the CAD line data and the bridge, as well as the number of loops, wherein the total path includes a number of loops and the paths of the multiple loops. Specifically, it includes:

[0078] When a distribution box and the CAD line data exist in each of the loops, determining whether the distance between the distribution box and the CAD line data is less than a first preset distance, and determining whether the distance between two adjacent CAD line data is less than a second preset distance; if the distance is less than the first preset distance and less than the second preset distance, determining that the distribution box and the CAD line data are connected, and two adjacent CAD line data are connected; determining a total path of the three-dimensional model based on the connected distribution box and the CAD line data, and the connected two adjacent CAD line data;

[0079] When a distribution box, the CAD line data and a bridge exist in each of the loops, determine whether the distance between the distribution box and the CAD line data is less than a first preset distance, determine whether the distance between two adjacent CAD line data is less than a second preset distance, and determine whether the distance between the CAD line data and the bridge is less than the first preset distance; if it is less than the first preset distance and less than the second preset distance, determine that the distribution box is connected to the CAD line data, two adjacent CAD line data are connected, and the CAD line data is connected to the bridge; based on the connected distribution box and the CAD line data, the connected two adjacent CAD line data, and the connected CAD line data and the bridge, determine the total path of the three-dimensional model.

[0080] Optionally, Figure 2 FIG. 1 is a schematic diagram showing a structure in which CAD data is connected to a bridge and adjacent CAD lines according to an exemplary embodiment. Figure 2 shown

[0081] Starting with the distribution box as the starting point, the two sets of line components (the CAD line data obtained in step S101 and the existing 3D bridge model) are checked to see if they are connected. If there are always connected line components, the process continues; otherwise, the process stops. These line components connected in pairs from the distribution box represent the total path of all circuits under this distribution box.

[0082] Specifically, it is determined whether a distribution box and the CAD line data exist simultaneously in each of the loops. When a distribution box and the CAD line data exist simultaneously in each of the loops, it is determined whether the distance between the distribution box and the CAD line data is less than a first preset distance. If it is less than the first preset distance, it is considered that the distribution box is connected to the CAD line data. And it is determined whether the distance between two adjacent CAD line data is less than a second preset distance. If it is less than the second preset distance, it is considered that the two adjacent CAD line data are connected. Through distance judgment, it is possible to ensure the connection between the distribution box and the CAD line data, and that the two adjacent CAD line data are connected, thereby determining the path of each loop. Based on the paths of each loop, the total path of the three-dimensional model can be determined.

[0083] Determine whether a distribution box, the CAD line data and a bridge exist simultaneously in each of the loops. When a distribution box, the CAD line data and a bridge exist simultaneously in each of the loops, determine whether the distance between the distribution box and the CAD line data is less than a first preset distance. If it is less than the first preset distance, it is considered that the distribution box is connected to the CAD line data. Determine whether the distance between two adjacent CAD line data is less than a second preset distance. If it is less than the second preset distance, it is considered that the two adjacent CAD line data are connected. Determine whether the distance between the CAD line data and the bridge is less than the first preset distance. If it is less than the first preset distance, it is considered that the CAD line data is connected to the bridge. Through distance judgment, it can be ensured that the distribution box is connected to the CAD line data, the two adjacent CAD line data are connected, and the CAD line data is connected to the bridge, thereby determining the path of each loop. Based on the paths of each loop, the total path of the three-dimensional model can be determined.

[0084] It is worth noting that the first preset distance is 0-30mm, and in the embodiment of the present application, 20mm can be used. The second preset distance is 0-1500mm, and in the embodiment of the present application, 1000mm can be used. To determine whether the distribution box and the bridge are connected, and whether the bridges are connected, it is through determining that the two are connected if they intersect. In each loop, it is also necessary to determine whether the distribution box and the bridge are connected, and whether the bridges are connected. The bridge refers to the laying of wires in the bridge, and the CAD lines refer to the laying of wires through pipes. The wires will not be broken in a path, part of them are in the pipe, part of them are in the bridge, they may all be in the pipe, or they may all be in the bridge.

[0085] Step S103 uses multiple judgment rules and built-in error settings to accurately determine the total path of the 3D model. This process not only improves the accuracy and continuity of path determination, but also simplifies user operations, reduces human error, and ensures the standardization and reliability of the design.

[0086] Figure 3is a flowchart of step S104 according to an exemplary embodiment. Figure 3 As shown, step S104, based on the positional relationship between the insertion point of the lamp and the bridge, and based on the distance between the lamp and the total path, determines the number and position information of each lamp on the total path. Specifically includes:

[0087] Step S1041: determine whether the insertion point of the lamp is within the width of the bridge, and determine whether the closest distance between the outer frame of the lamp and the CAD line of the total path is less than a first preset distance.

[0088] Step S1042: When the insertion point of the lamp is within the width of the bridge and the closest distance between the outer frame of the lamp and the CAD line of the total path is less than a first preset distance, determine the number and position information of each lamp on the total path.

[0089] Optionally, Figure 4 is a schematic diagram of a total path lamp according to an exemplary embodiment. Figure 4 As shown, it is determined whether the luminaire's insertion point is within the bridge width and whether the closest distance between the luminaire's outer frame and the overall path CAD line is less than a first preset distance. If the luminaire's insertion point is within the bridge width and the closest distance between the luminaire's outer frame and the overall path CAD line is less than the first preset distance, the number and position information of each luminaire on the overall path are determined. The first preset distance can be 20 mm. The position information is for the luminaire on the bridge and the overall path.

[0090] S104 ensures that the luminaire's insertion point is within the bridge's width by determining whether it is within the bridge's width, thus avoiding misjudgment of the luminaire's position. By determining whether the distance between the luminaire's insertion point and the overall path is less than a first preset distance (e.g., 20 mm), the luminaire's insertion point is ensured to be on the overall path, further improving the accuracy of position determination. The number and location of each luminaire on the overall path are accurately determined. This process not only improves the accuracy of luminaire position determination and the rationality of luminaire layout, but also simplifies user operation, reduces human error, and ensures design standardization and reliability.

[0091] In one embodiment, before step S105, based on the shortest path between lamps, starting from the distribution box, connecting lamps with the same label in the same circuit to generate a three-dimensional path and engineering quantity for each lighting circuit, the method further includes:

[0092] Determine whether the distance between the dimension mark of the lamp and the CAD line is less than a preset maximum distance value. If the distance is less than the preset maximum distance value, determine the CAD text mark corresponding to each lamp;

[0093] Based on the CAD text annotation corresponding to each lamp, the circuit name and circuit number corresponding to each CAD text annotation are determined.

[0094] Optionally, Figure 5 is a schematic diagram showing lamp marking according to an exemplary embodiment, such as Figure 5 As shown, determine whether the distance between the dimension mark of the lamp and the CAD line is less than the preset maximum distance value. If it is less than the preset maximum distance value, determine the CAD text mark corresponding to each lamp. The distribution box is the starting node, and the other ends are the end nodes. There can be multiple end nodes. The lamps from the lamp pointed to by the CAD text mark to the end node / next CAD text mark are assigned the circuit name and number represented by the mark. For example Figure 4 , the nine luminaires between the CAD text label "3AL-N1, N2" and the end node 3 are assigned circuit N1 / N2. Starting from the distribution box, the first luminaire assigned N1 / N2 is labeled N1, the second N2, the third N1, and so on to the luminaires at the end nodes. This determines the labeling of each luminaire.

[0095] Specifically, in the design drawings, each circuit under the distribution box will have a circuit number, generally a letter and a number. In the above example, N1 refers to the circuit. In the alternate lighting drawings, "3AL-N1, N2" indicates that there are two circuits, N1 and N2, at this location. These two circuits alternately connect to the lamps, meaning N1 connects to lamps 1, 3, and 5, and N2 connects to lamps 2, 4, and 6. The software handles this by first assigning N1 / N2 to lamps 1 through 6, grouping lamps with the same designation. Then, within this group, determine which lamps are 135 and which are 246.

[0096] S104 determines the CAD text annotation corresponding to each luminaire if the distance is less than the preset maximum distance. This ensures that each luminaire is correctly associated with the corresponding circuit annotation. Based on the CAD text annotation corresponding to each luminaire, the circuit name and number of each luminaire are determined using the circuit name and number corresponding to each CAD text annotation. This ensures the correct association between luminaires and circuits, providing accurate data support for subsequent path generation and engineering quantity calculations.

[0097] Step S105: Based on the number and location information of each lamp on the total path and the shortest path between lamps, starting from the distribution box, connect each lamp with the same label on the same circuit to generate a three-dimensional path and engineering quantity for each lighting circuit.

[0098] Optionally, Figure 6is a schematic diagram showing the shortest distance between lamps according to an exemplary embodiment. Figure 6 As shown in the figure, starting from the distribution box, according to the shortest path between lamps, all lamps with the same label are connected by wires with the same name circuit, which can generate the three-dimensional path and engineering quantity of each wire and each lighting circuit under the distribution box. Among them, the shortest distance between lamps is as shown in the figure. Figure 5 In the example, starting from the distribution box, loop N1 first connects to lamps 1 and 2. Path 1 then connects from lamp 2 to lamp 3, and path 2 connects from lamp 1 to lamp 3. Comparing the distances (adding the dimension numbers), path 1 is shorter. Therefore, the 3D model and engineering quantities for loop N1 are generated based on path 1.

[0099] Specifically, the BIM model of each circuit is established through the BIM installation quantity calculation software. The circuit has its own three-dimensional component model style in the BIM software. Each circuit is drawn from the distribution box along the analyzed shortest path to the end using the three-dimensional components of the circuit. This circuit space model software will give a height attribute, and customers can also define the height themselves. The three-dimensional models of the distribution box and lamps also have height attributes. Therefore, based on the above path, the three-dimensional path and engineering quantity of each lighting circuit can be generated. Step S105 connects the lamps through the shortest path, reducing the length of the wires and thus reducing material costs. For example, Figure 5 In the example, loop N1 originates from the distribution box, first connecting luminaires 1 and 2. It then follows path 1 (from luminaire 2 to luminaire 3) rather than path 2 (from luminaire 1 to luminaire 3) because path 1 is shorter, thus saving wires. Based on the generated 3D path, the system automatically calculates required quantities, such as wire length and number of connectors. This not only improves calculation accuracy but also significantly reduces the time and workload of manual calculations, increasing the efficiency of modeling and quantity calculations. Accurate quantity calculations enable more precise cost estimates, helping project managers better control budgets. Construction personnel can quickly and accurately complete wiring work based on detailed 3D path and quantity data, improving construction efficiency.

[0100] In summary, embodiments of the present application provide a lighting circuit modeling and quantity calculation method. This method obtains CAD line data and CAD text annotation data from a two-dimensional drawing. Each CAD text annotation is matched with a circuit number regular expression to determine the circuit name and number corresponding to each CAD text annotation. Based on the distance between the CAD line data and the bridge, as well as the number of circuits, a total path for the three-dimensional model is obtained, where the total path includes multiple circuits and the paths of multiple circuits. Based on the positional relationship between the luminaire insertion point and the bridge, and the distance between the luminaire and the total path, the number and position information of each luminaire on the total path are determined. Based on the number and position information of each luminaire on the total path, the method connects luminaires with the same annotations on the same circuit starting from the distribution box according to the shortest path between luminaires, generating a three-dimensional path and quantity for each lighting circuit. This method enables the simultaneous generation of a three-dimensional model for each circuit and real-time quantity calculation from centrally annotated interval luminaire drawings, saving staff the labor cost of drawing matching, improving the accuracy of automated quantity calculation tasks, and enhancing the efficiency of modeling and quantity calculation. This method addresses the low efficiency of interval luminaire lighting circuit modeling and quantity calculation in related technologies.
