An electrical floor plan shows the layout of electrical equipment and wiring on the building surface, including the location of electrical equipment and the routing of cables. An electrical system diagram is a schematic diagram that depicts the relationships between various cables and electrical equipment (including the components within those equipment).

[0003] Traditional electrical design drawings are manually created using computer-aided design software. This involves drawing icons for each electrical device and the wiring between them. However, in real-world projects, the sheer number of electrical devices, the complex design and construction specifications, and the complex wiring connections make drawing a labor-intensive process, prone to errors, and inefficient.

[0017] S214: traverse each icon in the second icon group and record the third icon code of each icon closest to the first icon group;

[0018] S215: Duplicate the code of the third icon in the first icon sorting table into two, insert the code of the second icon between the two identical codes, to form a second icon sorting table, and so on;

[0019] S216: Counting the number of icons in the second sorting table in order, and adding a code of an isolation module after a certain number of icons, to form a third sorting table of ring wiring;

[0052] The accompanying drawings are for illustrative purposes only and are not to be construed as limiting this patent;

[0053] The present invention is further described below with reference to the accompanying drawings and embodiments.

[0054] Example 1

[0055] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a method for automatically drawing electrical drawings includes the following steps:

[0056] S1: Create icons of multiple electrical devices to form an icon group;

[0057] S2: Apply the ring connection method, chain connection method, and tree connection method to the icon group and come up with three connection schemes;

[0058] S3: Automatically draw electrical drawings based on three connection schemes.

[0059] In the above scheme, different connection schemes are obtained for the equipment icons in the electrical drawings using the ring connection method, chain connection method, and tree connection method respectively. Moreover, for the same connection method, multiple groups of icons with different installation methods are combined to realize the automatic drawing of the plane wiring and system diagram of the electrical drawings, greatly improving the efficiency and accuracy of the drawing.

[0060] Preferably, in step S1, icons of different types are created and divided into different icon groups according to different installation methods; the icons are classified into at least:

[0061] A first icon group in a first electrical system with installation mode one (e.g., ceiling installation);

[0062] A second icon group in the first electrical system with installation mode two (e.g., wall installation);

[0063] The Nth icon group in the first electrical system with installation method N (e.g., ground installation);

[0064] The second electrical system, the third electrical system and so on.

[0065] Preferably, in step S2, the ring connection method includes the following steps:

[0066] S211: Select several icon groups that need to be connected in a ring;

[0067] S212: using the shortest path algorithm of TSP, determining a first ring connection scheme between the first icon groups;

[0068] S213: Determine the first icon of the first ring connection scheme, and start sorting the icons one by one until the connection returns to the first icon, record the code of each icon, and generate a first icon sorting table;

[0069] S214: traverse each icon in the second icon group and record the third icon code of each icon closest to the first icon group;

[0070] S215: Duplicate the code of the third icon in the first icon sorting table into two, insert the code of the second icon between the two identical codes, to form a second icon sorting table, and so on;

[0071] S216: Counting the number of icons in the second sorting table in order, and adding a code of an isolation module after a certain number of icons, to form a third sorting table of ring wiring;

[0072] In the above scheme, the connection requirements of certain electrical equipment require the addition of some safety devices, such as the isolation module of the automatic fire alarm system. It is required that an isolation module be added for no more than 32 devices on the connection line. In this way, when the fire alarm connection line is short-circuited in some devices, one end can be isolated, and the host communicates through the line at the other end to ensure that the entire line is not affected.

[0073] S217: Each icon records where it comes from and where it leads to, and obtains a first connection plan.

[0074] Preferably, in step S212, the shortest path algorithm of the TSP includes but is not limited to ant colony algorithm, annealing algorithm, genetic algorithm and particle ensemble algorithm.

[0075] Preferably, in step S2, the chain connection method includes the following steps:

[0076] S221: Select several icon groups that need to be connected in a chain;

[0077] S222: Determine the first root icon of the chain line in the icon group, search for and record the second root icon closest to the first root icon, then search for the third root icon closest to the second root icon, and so on;

[0078] S223: Each icon records where it comes from and where it leads to, and obtains a second connection plan.

[0079] Preferably, in step S2, the tree connection method includes the following steps:

[0080] S231: Determine a number of icon groups that need to be connected in a tree-like manner;

[0081] S232: Determine the root icon of the chain connection in the icon group, and perform tree connection using the shortest path solution of the tree connection obtained by the minimum spanning tree algorithm;

[0082] S233: Each icon records where it comes from and where it leads to, and a third connection plan is obtained.

[0083] Preferably, in step S232, the minimum spanning tree algorithm includes but is not limited to Kruskal algorithm and Prim algorithm.

[0084] Preferably, in step S3, electrical drawings are automatically drawn according to the first, second and third connection schemes. Specifically, when a system diagram is generated according to the first connection scheme, icons of the system diagram are generated in sequence according to the arrangement table, and the same blocks are merged and counted when drawing the system diagram; the second and third connection schemes draw a short line above the icon to connect to the respective system main lines.

[0085] Example 2

[0086] like Figure 5 As shown, the icons on the diagram are classified using the legend table. This example is divided into four categories:

[0087] The first category is for ceiling installation, which requires ring wiring icon category;

[0088] The second category is for wall mounting, which requires ring wiring icon category;

[0089] The third category is the icon category that requires chain wiring;

[0090] The fourth category is the icon category that requires tree wiring;

[0091] Specific connection method:

[0092] 1) If Figure 6 As shown, select the icon group of a certain area

[0093] like Figure 7 and Figure 8 As shown, by grouping icons in advance, the first icon group that needs to be connected in a ring is connected using the shortest path algorithm of TSP (such as ant colony algorithm, annealing algorithm, genetic algorithm, particle group algorithm, etc.) to determine the first ring connection scheme between the first icon groups;

[0094] like Figure 9 As shown, a first icon of a first ring connection scheme is determined;

[0095] Sort the icons one by one starting from the first icon until the line returns to the first icon, record the code of each icon, and generate the first icon sorting table (a1, a2, a3, a4...);

[0096] Traverse each icon in the second icon group and record the third icon code (b1) of each icon (second icon a2) closest to the first icon group, such as Figure 10 As shown;

[0097] Duplicate the code of the third icon in the first icon sorting table into two, and insert the second icon code (b1) between the two identical codes to form the second icon sorting table (a1, a2, b1, a2, a3, a4...)

[0098] And so on.

[0099] Each icon records where it comes from (icon additional code 1) and where it leads to (icon additional code 2) to obtain the first connection plan.

[0100] The connection requirements for some electrical equipment also require the addition of some safety devices, such as the isolation module of the automatic fire alarm system. It is required that an isolation module be added for no more than 32 devices on the connection line. In this way, when the fire alarm connection line is short-circuited in some devices, one end can be isolated, and the host communicates through the line at the other end to ensure that the entire line is not affected.

[0101] like Figure 11 and Figure 12 As shown, therefore, in the second sorting table, the number of icons is counted in order, and an isolation module code is added after a certain number of icons (for example, 25), and at the same time, a corresponding isolation module icon is added to the plan view.

[0102] In this way, the third sorting table of the final ring connection is formed.

[0103] (g1, a1, a2, b1, a2, a3, a4…a24, g2, a25…)

[0104] 2) If Figure 13 As shown, determine the icon group that needs chain connection. In this case, the icon group for tree connection is the third icon group.

[0105] Determine the root icon (fourth icon) of the chain connection scheme in the third icon group, search for and record the fifth icon closest to the fourth icon, then search for the sixth icon closest to the fifth icon... and so on;

[0106] Each icon records where it comes from (icon additional code 1) and where it leads to (icon additional code 2) to obtain the second connection plan.

[0107] 3) If Figure 14 and Figure 15 As shown, determine the icon group that needs tree wiring. In this case, the icon group for tree wiring is the fourth icon group.

[0108] Determine the root icon (the seventh icon) of the chain connection scheme in the fourth icon group, and use the minimum spanning tree algorithm (such as Kruskal algorithm, Prim algorithm, etc.) to obtain the overall shortest path scheme of the tree connection to perform tree connection; each icon records where it comes from (icon additional code 1) and where it leads to (icon additional code 2) to derive the third connection scheme.

[0109] like Figure 16 As shown, a fire alarm system diagram is automatically drawn according to the first, second and third connection schemes.

[0110] Among them, when generating a system diagram according to the first connection scheme, the system diagram icons are generated in sequence according to the arrangement table. Due to industry habits, the same blocks are merged and counted when drawing the system diagram, so a simple cumulative merging calculation is required.

[0111] The third connection solution only requires drawing a short line above the icon and connecting it to the respective system main line.

[0112] Example 3
