Abstract
Description
Technical Field
[0001] This invention relates to the field of resource recommendation technology, and more specifically, to a method for recommending resources for the standardized design of pump rooms and machine rooms in electromechanical installation engineering. Background Technology
[0002] In civil electromechanical installation projects, the installation of pump rooms and machine rooms involves complex pipelines, numerous valves and pipe fittings. Traditional construction methods often result in two-dimensional architectural design drawings failing to perfectly represent the accurate design, leading to many design problems going undetected during the design phase. Discovering these issues after actual construction results in significant rework and resource waste. In the design of machine rooms and pump rooms, designers often arbitrarily place valves and pipe fittings, leading to numerous design variations for the same pipelines and fittings. This makes it difficult to achieve project uniformity, resulting in a poor construction aesthetic. Furthermore, designers often lack understanding of actual on-site electromechanical construction, causing many electromechanical elements to fail to meet construction requirements, necessitating secondary design refinement for certain aspects.
[0003] To address the aforementioned shortcomings, a technical solution is provided. Summary of the Invention

[0018] Based on the historical operating data of the pump unit module, the types of pipe segments used in the pump unit module and the number of different pipe segment types are obtained from the historical operating data. Based on the abnormal events of pipe segment types in the historical operating data, the impact score of different pipe segment types is determined.
[0019] Based on the pipe segment coding vector formed by a specific pump unit module, a regression model is constructed by combining the influence score of pipe segment type in the pipe segment coding vector with the quantity corresponding to the pipe segment type, generating a connection mismatch coefficient. The formula for calculating the connection mismatch coefficient is as follows:
[0020]
[0021] Among them, SL1, SL2, SL3, ..., SL N The number of different pipe segment types: PF1, PF2, PF3, ..., PF N The impact score for pipe segment type is α1, α2, α3, ..., α N Weights for different pipe segment types.
[0022] In a preferred embodiment, the logic for obtaining the spatial angle anomaly coefficient is as follows:
[0023] Based on the pipe segment coding vector of a specific pump unit module, the 3D model of the pump unit is determined, and the pipe segment angle of each pipe segment in the specific pump unit module is obtained.

If the design evaluation coefficient is greater than the design evaluation coefficient threshold, the pipe segment coding vector is not marked.
[0030] The technical effects and advantages of this invention are as follows:
[0031] This invention standardizes design outcomes. Previously, designs in machine rooms or pump rooms lacked standardized formats, such as the positional relationships of pipes, valves, instruments, and other pipe accessories before and after the pump. Now, through a standard pump set module selection library, design standardization is improved, and the pipelines in pump rooms and machine rooms are streamlined, facilitating prefabrication and production. This also promotes standardized design, enhancing pipeline uniformity. For most detailed designers, selecting pump sets only requires flow rate and head matching, which is very simple and can be accomplished with minimal training. Unlike traditional design software, which requires designers to have a systematic design foundation and comprehensive training, this invention improves design efficiency in engineering.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0038] Example 1
[0039] Figure 1This is a flowchart illustrating the method for recommending standardized design resources for pump rooms and machine rooms in electromechanical installation engineering according to the present invention, which specifically includes the following steps:
[0040] S1: Build accurate pump room and machine room models using BIM technology, create a standard pump group module selection library and a standardized pipe section selection library, and generate detailed drawings and 3D models of the pump group.
[0041] S2: Select a pump module from the standard pump module selection library according to project requirements, and select a pipe segment compatible with the pump module from the standardized pipe segment selection library. Use the pipe segment compatible with the pump module as a spare pipe segment and generate a pipe segment coding vector for a specific pump module.
[0042] S3: By collecting the spare pipe sections of a specific pump unit module, determine the compatibility and spatial information of the spare pipe sections;
[0043] S4: Perform a comprehensive analysis of the adaptation information and spatial information of the spare pipe section, quantify the pipe section coding vector generated by the specific pump unit module, and judge the rationality of the pipe section coding vector by threshold comparison.
[0044] Creating a standard pump unit module selection library, building pump house and machine room models using BIM technology, and conducting detailed design of pump unit modules within these models enables more accurate, intuitive, and unified pump house and machine room designs. This also optimizes the design process, improving design efficiency and accuracy, including:
[0045] BIM technology is used to build models of pump rooms and machine rooms. Utilizing BIM, all equipment, pipes, supports, valves, instruments, etc., within the pump room and machine room are created in 3D. BIM accurately reflects the spatial layout of the pump room and machine room, as well as the relative positions, dimensions, and functions of each piece of equipment and component. BIM helps designers analyze the effective use of space, ensuring that the installation of pump modules is not interfered with by other equipment or pipes, reducing the need for redesign due to space conflicts. Through virtual modeling, potential spatial conflicts can be identified in advance and optimized accordingly.
[0046] The pump module is designed in detail according to project requirements. Different types of pump modules (such as single pump modules, parallel pump modules, variable frequency pump modules, etc.) are designed. Each pump module includes necessary components such as pumps, pipes, valves, reducers, flexible joints, and instruments.
[0047] It should be noted that the design of each pump set must take into account the water inlet and outlet methods. For example, pump sets may be of different forms such as single inlet single outlet, single inlet double outlet, and double inlet single outlet. These need to be accurately represented in the model. According to the different uses of the pump room or machine room, such as fire pump room, water supply pump room, and drainage pump room, the configuration of the pump set modules should be adjusted to ensure that each module can meet the working requirements under specific operating conditions.
[0048] Data accumulation and layout optimization: By continuously accumulating actual project operation data, we analyze the efficiency, space occupation, and energy consumption of pump sets under different layout methods. Using data analysis tools in BIM software, we help designers compare the advantages and disadvantages of different layout methods and select the optimal solution.
[0049] The integration of detailed drawings and 3D models, based on the BIM model, generates detailed drawings of the pump set, including pump dimensions, piping layout, valve locations, reducers, and installation methods for flexible joints. These detailed drawings provide clear installation guidance for the construction team, avoiding installation errors caused by unclear design drawings. Using the 3D BIM model, designers can view the actual installation effect of pump sets, piping, valves, and other equipment in a virtual environment, ensuring coordination between various devices. Through the 3D model, the construction team can more intuitively understand the design requirements, reducing misunderstandings and deviations during construction.
[0050] It should be noted that by creating a standard pump module selection library, designers only need to select the appropriate pump module from the library based on the pump room's flow rate requirements and head. The library already has preset configurations and layouts for different types of pumps, which designers can directly select and make simple adjustments, reducing the time spent on manual design and repeated modifications.
[0051] Figure 2 The standard pump unit module uses detailed drawings of two horizontal end-suction pump units from the library. Figure 3 The three-dimensional model of the three pump group module in the library is selected for the standard pump group module.
[0052] The standardized pipe section selection library is a tool for the systematic and modular design of common pipelines in pump rooms and machine rooms. By collecting, organizing, and standardizing different pipe types, it divides pipelines into multiple standard pipe sections and provides detailed design drawings, large-scale drawings, and 3D models for each section, greatly improving design and construction efficiency. This includes:
[0053] Based on the common pipe types and uses in pump rooms and machine rooms, the pipes are classified. Through data statistics and experience summary, several standard pipe sections are identified. These standard pipe sections can cover the pipe requirements of most pump rooms and machine rooms. Each standard pipe section has clear specifications, dimensions and interface methods to adapt to different pipe layout requirements.
[0054] Based on different project requirements and the layout of pump rooms and machine rooms, we collect all common pipe specifications, types and their connection methods in pump rooms. We organize and classify the collected pipe data (such as pipe diameter, length, material, interface type, etc.) to ensure that each pipe segment in the pipe segment library can meet the requirements of different working conditions. The organization process also includes the selection of auxiliary components such as pipe fittings, joints, valves, and reducers to ensure that each pipe segment can be installed completely.
[0055] For each standard pipe section, a corresponding detailed drawing is created. The detailed drawing includes the pipe section's dimensions, interface locations, connection methods, and the installation locations of pipe accessories (such as valves, reducers, etc.). Each standard pipe section is also accompanied by a 3D model. Through BIM (Building Information Modeling) technology, each pipe section and its components are modeled as 3D graphics. Designers can check the dimensions, locations, and coordination with other pipe sections in a virtual environment to ensure the feasibility of the design scheme.
[0056] Figure 4 Use the pipe segment breakdown diagram from the library to standardize pipe segments.
[0057] Before project construction begins, the designer first selects a suitable pump module from the standard pump module selection library based on project requirements (such as flow rate, head, pump type, etc.). Based on the selected pump module, compatible pipe sections are then selected from the standardized pipe section selection library. These compatible pipe sections are then used as backup pipe sections. For a specific pump module (i.e., the one selected by the designer), a specific pipe section coding vector corresponds to a specific pump module. Each element in the pipe section coding vector represents a specific pipe section type, and there are multiple selection options for pipe section types. For example, the pipe section coding vector corresponding to a specific pump module might be: Wherein, J, C, and Z represent the pipe segment types required by a specific pump unit module, such as inlet pipe segment, outlet pipe segment, and branch pipe segment. Different pipe segment types may have different materials or specifications. a, b, and d represent the numbers of different materials or specifications under different pipe segment types. e, f, and g represent the number of pipe segments required by a specific pump unit module for each pipe segment type in the pipe segment coding vector.
[0058] It should be noted that each pump module may require multiple pipe sections (e.g., inlet pipe section, outlet pipe section, branch pipe, etc.) during the design process. The selection of each pipe section may vary depending on the actual needs of the project, including different specifications, materials, and connection methods. The purpose of the pipe section coding vector is to list all the pipe section types required by the pump module and their different selections, thereby providing designers with an accurate pipe section matching solution.
[0059] By collecting the spare pipe sections of a specific pump unit module, the compatibility and spatial information of the spare pipe sections are determined. The compatibility information of the spare pipe sections is represented by the pipe diameter compatibility deviation coefficient and the connection mismatch coefficient, and the spatial information of the spare pipe sections is represented by the spatial angle anomaly coefficient.
[0060] The logic for obtaining the pipe diameter adaptation deviation coefficient is as follows: determine the pipe segment coding vector of a specific pump group module; based on the pipe segment coding vector, obtain the pipe segment type required by the specific pump group module and the quantity corresponding to each pipe segment type; obtain the ideal pipe diameter of the pipe segment type required by the specific pump group module; and mark the ideal pipe diameter of the pipe segment type required by the specific pump group module as: n is the element number in the pipe segment coding vector, and i is the number of different pipe diameters under each pipe segment type in the pipe segment coding vector of a specific pump group module.
[0061] It should be noted that pipeline design and construction typically allow for a certain range of deviation. If the pipe diameter is small, at the same flow rate, a smaller diameter will lead to a higher flow velocity. Although this may meet the flow rate requirement, excessive flow velocity may result in significant pressure loss, thereby affecting pump efficiency. If the pipe diameter is too large, the larger the pipeline, the more space it occupies, and layout adjustments may be necessary within a limited space. The ideal pipe diameter is calculated based on factors such as flow rate, head, and pipeline velocity, and the design pipe diameter is usually a theoretical value.
[0062] The formula for calculating pipe diameter deviation is as follows: in, For a specific pump unit module, the diameter deviation of the i-th specification of the n-th pipe section type is given. The actual pipe diameter required for the type of pipe section needed for a specific pump unit module;
[0063] It should be noted that a specific pump module can generate multiple pipe segment coding vectors, resulting in a variety of combinations of pipe segment types. Under each pipe segment type, there are differences in pipe diameter based on the pipe segment specifications, which leads to each combination corresponding to a specific set of pipe segment coding vectors.
[0064] The formula for calculating the pipe diameter fit deviation coefficient is as follows: Among them, GJ sp Where I is the pipe diameter adaptation deviation coefficient, N is the number of pipe segment types in the pipe segment coding vector, and I is the pipe diameter adaptation deviation coefficient. n This represents the number of different pipe diameters for each pipe segment type.
[0065] As can be seen from the formula, the larger the pipe diameter adaptation deviation coefficient, the lower the pipe diameter adaptation of the pipe segment coding vector formed by a specific pump module. This may lead to instability in system operation, and may even require readjustment of the pump's operating point or modification of the pipe segment specifications to achieve a good adaptation effect.
[0066] The logic for obtaining the connection mismatch coefficient is as follows: Based on the historical operating data of the pump group module, the pipe segment type and the number of different pipe segment types used in the pump group module are obtained from the historical operating data. Based on the abnormal events of the pipe segment type in the historical operating data, the impact score value of different pipe segment types is determined.
[0067] It should be noted that abnormal events can include abnormal flow, pressure fluctuations, pump set failures, and system instability. Based on the abnormal events that occur in historical operating data, the impact score of each pipe section type is evaluated. The impact score reflects the impact of each pipe section type on the performance of the pump set module, especially the impact related to system failures or abnormal events. The impact score can be scored by experts.
[0068] Based on the pipe segment coding vector formed by a specific pump unit module, a regression model is constructed by combining the influence score of pipe segment type in the pipe segment coding vector with the quantity corresponding to the pipe segment type, generating a connection mismatch coefficient. The formula for calculating the connection mismatch coefficient is as follows:
[0069]
[0070] Among them, HL lj To connect unreasonable matching coefficients, SL1, SL2, SL3, ..., SL N The number of different pipe segment types: PF1, PF2, PF3, ..., PF N The impact score for pipe segment type is α1, α2, α3, ..., α N Weights for different pipe segment types.
[0071] As can be seen from the formula, the larger the mismatch coefficient, the higher the risk of failure or performance instability of the pipe segment encoding vector generated by a specific pump module. This indicates that the selection of certain pipe segments in the system may lead to more frequent abnormal events, performance degradation, or failures.
[0072] The logic for obtaining the spatial angle anomaly coefficient is as follows: Based on the pipe segment coding vector of a specific pump group module, determine the three-dimensional model of the pump group, obtain the pipe segment angle of each pipe segment in the specific pump group module, and mark the pipe segment angle of each pipe segment in the specific pump group module as: JD m Where m = 1, 2, 3, ..., M, M is a positive integer, and m is the number of different pipe segments in the pipe segment coding vector;
[0073] Calculate the mean and standard deviation of the pipe segment angles in the pipe segment coding vector, and label the mean and standard deviation of the pipe segment angles in the pipe segment coding vector as: JD avg and JD std ,in,
[0074] It should be noted that a larger standard deviation of the pipe segment angle in the pipe segment coding vector indicates a greater variation in angle within the pipe. This can increase the complexity of fluid flow, thereby increasing flow resistance, pressure loss, and potentially even causing unstable flow conditions. Such a pipe system design may consume more energy, reduce pump efficiency, and even increase the difficulty of construction and maintenance.
[0075] The formula for calculating the spatial angular anomaly coefficient is as follows: Among them, YC jd This is the spatial angular anomaly coefficient.
[0076] As can be seen from the formula, the larger the spatial angle anomaly coefficient, the more likely the pump set may cause drastic changes in fluid flow, thereby increasing flow resistance, pressure loss and pump load. Design based on pipe segment coding vectors may affect the efficiency and stability of the system.
[0077] By comprehensively analyzing the compatibility and spatial information of the spare pipe section, and weighting the calculations using pipe diameter compatibility deviation coefficient, connection mismatch coefficient, and spatial angle anomaly coefficient, a design evaluation model is constructed, generating design evaluation coefficients. The formula for calculating the design evaluation coefficients is: pg sj =β1GJ sp + β2HL lj +β3YC jd Among them, pg sj β1, β2, and β3 are the design evaluation coefficients for the pipe segment coding vector, and the proportional coefficients for the pipe diameter adaptation deviation coefficient, the unreasonable connection matching coefficient, and the spatial angle anomaly coefficient, respectively. β1, β2, and β3 are all greater than 0.
[0078] Set a design evaluation coefficient threshold, obtain all pipe segment coding vectors generated by a specific pump unit module, and obtain the design evaluation coefficients of all pipe segment coding vectors. Compare the design evaluation coefficients with the design evaluation coefficient threshold. If the design evaluation coefficient is less than the design evaluation coefficient threshold, the pipe segment coding vector is marked, indicating that the design of the pipe segment coding vector is unreasonable. If the design evaluation coefficient is greater than the design evaluation coefficient threshold, the pipe segment coding vector is not marked, and the pipe segment type in the unmarked pipe segment coding vector is recommended to the designer, indicating that the pipe segment coding vector design is better and can effectively reduce energy loss and failure rate.
