[0029] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 The first embodiment of the device loop generation method in this invention includes:

[0030] 101. Obtain the electrical equipment information of the electrical equipment in the water supply and drainage professional model and the heating, ventilation and air conditioning professional model respectively, and update the electrical equipment information to the electrical professional model;

[0031] In this embodiment, the water supply and drainage (PHL) and HVAC (Heating, Ventilation, and Air Conditioning) disciplines create their respective electrical equipment and design information in the PHL and HVAC models, respectively. The design information includes equipment names and power ratings. Equipment names must comply with the requirements of the "Forward Design Naming Standard Specification". Based on the professional collaboration model, the electrical model is loaded into the PHL and HVAC models via file links, enabling real-time, accurate, and efficient transfer of PHL and HVAC electrical equipment and related design information to the electrical model.

[0032] 102. Based on the preset matching table and electrical equipment information, draw the electrical symbols corresponding to the electrical equipment in the electrical professional model;

[0033] In this embodiment, based on the equipment name, the plug-in identifies water supply and drainage equipment such as grease traps, water pumps, electric valves, wet alarm valves, pre-action alarm valves, level gauges, flow switches, and fire hydrants, as well as HVAC equipment such as fans, exhaust fans, electric regulating valves, pressure relief valves, and fire dampers. Based on the "Matching Table of Electrical Equipment and Electrical Symbols," each electrical equipment is automatically matched with an electrical symbol type, and based on the acquired equipment location information, the corresponding electrical symbol is automatically drawn at the original location of the equipment.

[0034] 103. Obtain the path from the electrical equipment to the power source, and generate the corresponding equipment circuit in the electrical engineering model based on the path, electrical symbols, and electrical equipment information.

[0035] In this embodiment, the cable path from the power source point to the electrical equipment, planned by the designer, is obtained. The cable path can be laid in various ways, such as cable trays, cable trenches, buried pipes, or shafts. In the electrical engineering model, a single power source point can extend into several cable paths, and each cable path can contain several equipment loops leading to the corresponding equipment.

[0036] In this embodiment, the electrical equipment information of the electrical equipment in the water supply and drainage professional model and the heating, ventilation, and air conditioning professional model are obtained respectively, and the electrical equipment information is updated to the electrical professional model. Based on a preset matching table and the electrical equipment information, the electrical symbols corresponding to the electrical equipment are drawn in the electrical professional model, wherein the matching table includes the matching relationship between the electrical equipment and the electrical symbols. The path from the electrical equipment to the power supply point is obtained, and the corresponding equipment circuit is generated in the electrical professional model based on the path, the electrical symbols, and the electrical equipment information. This method obtains the electrical equipment of external disciplines in a collaborative mode, generates electrical symbols in the corresponding spatial positions of the electrical professional model through a preset matching table, and then generates the corresponding equipment circuit based on the electrical equipment information.

[0037] Please see Figure 2 The second embodiment of the device loop generation method in this invention includes:

[0038] 201. Based on the BIM collaborative mode, the water supply and drainage professional model and the HVAC professional model are loaded into the electrical professional model through file links;

[0039] In this embodiment, the BIM collaboration mode is a point-to-center information exchange mode. The information exchange between each participant is unique and continuous. This information communication mode integrates scattered data and information on a single platform, realizing data sharing between professions and making information communication smoother.

[0040] 202. Read the electrical equipment information from the water supply and drainage model and the heating, ventilation and air conditioning model;

[0041] In this embodiment, by obtaining the name and spatial coordinates of the electrical equipment, the plug-in identifies water supply and drainage equipment such as grease traps, water pumps, electric valves, wet alarm valves, pre-action alarm valves, level gauges, flow switches, and fire hydrants, as well as HVAC equipment such as fans, exhaust fans, electric regulating valves, pressure relief valves, and fire dampers, based on the equipment name or equipment ID value.

[0042] 203. Update the electrical equipment information to the corresponding location in the electrical engineering model based on spatial coordinates;

[0043] 204. Based on the preset matching table and electrical equipment information, draw the electrical symbols corresponding to the electrical equipment in the electrical professional model;

[0044] 205. Obtain the path from the electrical equipment to the power source, and generate the corresponding equipment circuit in the electrical engineering model based on the path, electrical symbols, and electrical equipment information;

[0045] 206. When the electrical engineering model is reopened, update the electrical equipment information of the water supply and drainage engineering model and the heating, ventilation and air conditioning engineering model to the electrical engineering model.

[0046] In this embodiment, after experiencing the equipment loop generation method in the initial collaborative mode, each time the electrical professional model is opened subsequently, the water supply and drainage professional model and the heating and ventilation professional model will be reloaded based on the original file connection method.

[0047] 207. Determine whether the spatial coordinates of electrical equipment in the water supply and drainage model and / or the heating, ventilation and air conditioning model have been modified;

[0048] In this embodiment, the electrical equipment in the water supply and drainage professional model and / or the heating and ventilation professional model is judged. There are two situations: modification of the spatial coordinates of the electrical equipment or addition or deletion of the electrical equipment. The judgment is made by matching the electrical equipment elements, equipment ID values, or equipment names, that is, by comparing the differences before and after updating the electrical equipment information of the water supply and drainage professional model and the heating and ventilation professional model to the electrical professional model.

[0049] Specifically, if there are differences in the electrical equipment elements, equipment ID values, or matching of equipment names before and after the update, it can be determined that the number of electrical equipment has increased or decreased after the update. If there are no differences in the electrical equipment elements, equipment ID values, or matching of equipment names before and after the update, the spatial coordinates of the electrical equipment are determined. By traversing the spatial coordinates of the electrical equipment before and after the update, the electrical equipment that has been modified is identified.

[0050] 208. If so, then the electrical equipment name in the electrical equipment information will be used to generate the corresponding electrical symbol through the matching table;

[0051] In this embodiment, if the spatial coordinates of the electrical equipment are modified, or if the electrical equipment is added or removed, based on step 207 of confirming the electrical equipment, the addition or removal of the electrical equipment is confirmed first, and then the spatial coordinates of the electrical equipment are confirmed. The electrical symbols corresponding to the changed electrical equipment and the equipment circuits corresponding to the electrical symbols are deleted. After deletion, based on the updated electrical equipment, the electrical symbol type is automatically matched for each electrical equipment through the "Electrical Equipment and Electrical Symbol Matching Table". Based on the obtained equipment location information, the corresponding electrical symbol is automatically drawn at the original position of the equipment.

[0052] 209. Place the generated electrical symbol at the modified spatial coordinates of the electrical equipment.

[0053] This embodiment, based on the previous embodiment, describes in detail the process of updating the electrical equipment information of the water supply and drainage model and the HVAC model to the electrical model after the electrical professional model is reopened; determining whether the spatial coordinates of the electrical equipment in the water supply and drainage model and / or the HVAC model have been modified; if so, generating corresponding electrical symbols from the electrical equipment names in the electrical equipment information through the matching table; and placing the generated electrical symbols at the modified spatial coordinates of the electrical equipment. Compared with traditional methods, this embodiment refines the method of reusing automatic drawing in the design process and clarifies the process of modifying the original electrical symbols by judging the increase or decrease in the number of electrical equipment and the change in spatial coordinates before and after the update.

[0054] Please see Figure 3 The third embodiment of the device loop generation method in this invention includes:

[0055] 301. Obtain the electrical equipment information of the electrical equipment in the water supply and drainage professional model and the heating, ventilation and air conditioning professional model respectively, and update the electrical equipment information to the electrical professional model;

[0056] 302. Based on the matching table, configure multiple types of electrical symbols for electrical engineering model design on the electrical engineering model;

[0057] In this embodiment, based on the "Matching Table of Electrical Equipment and Electrical Symbols", electrical symbols are configured according to the electrical equipment and design information of each discipline in the water supply and drainage professional model and the heating and ventilation professional model, and a mapping relationship between electrical equipment elements and electrical symbols is constructed. It also includes constructing a mapping relationship between design information and corresponding labels of electrical symbols. The design information should have a unified format and include parameters such as power and power factor of electrical equipment.

[0058] 303, a symbol component library for building electrical engineering models based on electrical symbols;

[0059] In this embodiment, for the electrical equipment and design information of each discipline in the water supply and drainage professional model and the heating and ventilation professional model, the corresponding electrical symbols are pre-configured in the symbol component library according to the relevant information such as standards and specifications obtained from the matching table, namely the "Matching Table of Electrical Equipment and Electrical Symbols".

[0060] 304, iterate through the electrical equipment information updated to the electrical professional model, and call the corresponding electrical symbols in the symbol component library based on the electrical equipment name in the electrical equipment information and the preset matching table;

[0061] 305. Generate corresponding power labels based on the power consumption of the electrical equipment;

[0062] In this embodiment, the generated power annotation is based on the design information provided by the respective disciplines in the water supply and drainage model and the heating, ventilation and air conditioning model, and the spatial coordinates generated by the power annotation are also based on the spatial coordinates of the applied electrical equipment.

[0063] 306. Draw the electrical symbols and power labels in the corresponding spatial coordinates of the electrical equipment in the electrical engineering model;

[0064] 307, Obtain the path from the electrical equipment to the power source;

[0065] In this embodiment, the designer plans the cable path and laying method from several electrical devices to the power source. Based on a certain arrangement of the electrical devices, the cables are laid from the designated path to the power source. The power source can be a power point with disconnection function and containing several outgoing line groups, such as a low-voltage outgoing cabinet, switch box, or junction box.

[0066] Specifically, the path and power source are not unique values. Based on the different specifications and types of electrical equipment, if different types of electrical equipment exist in the model, different paths and power sources need to be planned according to certain standards, specifications, and power factors to ensure the reliability of power supply.

[0067] 308. Determine whether the sum of the power of the electrical devices included in the path exceeds a preset power threshold.

[0068] In this embodiment, for the case where a power source is connected to a power device, it is determined whether the sum of the power of the power devices connected to the same power source exceeds a preset power threshold.

[0069] Specifically, if the preset power threshold is exceeded, it is necessary to add a power source, modify the specifications of the power source, or build a new power source from another transformer to prevent the current from exceeding the upper limit of the load rate of the transformer upstream of the power source.

[0070] 309. If not, then determine the loop parameters and loop spacing based on the number and power of the electrical equipment contained in the path, and generate the corresponding equipment loop;

[0071] In this embodiment, based on the preset path and the number of electrical devices, the number of circuits corresponding to the number of electrical devices is generated. Then, based on the power of the electrical devices and the connection method between the electrical devices, such as series, parallel or individual connection, the specifications and models of the cables used in each circuit are determined.

[0072] 310. When the electrical engineering model is reopened, update the electrical equipment information of the water supply and drainage engineering model and the heating, ventilation and air conditioning engineering model to the electrical engineering model.

[0073] 311. Summarize the total power of electrical equipment within the same power source point and determine whether the total power of the electrical equipment exceeds the preset power threshold.

[0074] 312. If the power exceeds the threshold, a prompt will be sent to the user requesting a new power source for the electrical equipment exceeding the power threshold.

[0075] This embodiment, based on the previous embodiment, describes in detail the process of obtaining the path from the electrical equipment to the power source; determining whether the sum of the power of the electrical equipment included in the path exceeds a preset power threshold; if not, determining the loop parameters and loop spacing based on the number and power of the electrical equipment included in the path, and generating the corresponding equipment loop. Compared with traditional methods, this embodiment refines the impact of parameters such as the power and number of electrical equipment on the generation method during the generation of electrical symbols and equipment loops. By using a preset power threshold to distribute power to electrical equipment based on factors such as the number of loops, the number of power sources, and the type of electrical equipment, the device loop of the selected electrical equipment is automatically drawn after determination.
