The present disclosure relates to the field of computer-aided design (CAD), and more particularly relates to automated design of a piping system.
CAD systems are used for designing, visualizing, and manufacturing simple and complex systems. CAD systems allow designers to design three-dimensional graphic models of systems such as piping systems before or instead of manufacturing physical items. Currently known CAD systems enable designing of three-dimensional graphical models of piping systems in an interactive manner which requires designers to provide a lot of inputs, such as to input appropriate piping components from a list of piping components and specify locations of the piping components along a piping path based on a piping and instrumentation diagram (P&ID) sheet. Due to this, designing of three-dimensional graphical models of entire piping systems using the known CAD systems may be error prone, tedious, and involve a time consuming process.
A data processing system for automated design of a piping system and method thereof is disclosed. In one aspect, a method of automated design of a piping system includes obtaining logical definition data of the piping system with one or more pipe runs from a computer-aided design (CAD) database, and computing a piping path for each pipe run based on the logical definition data of the piping system. The method includes determining positions of the one or more piping components for said each pipe run based on the computed piping path for said each pipe run, and associating the one or more piping components for said each pipe run with the determined positions of the piping components. Moreover, the method includes automatically generating a graphical model of the piping system based on the association of the one or more piping components with the determined positions for said each pipe run.
In another aspect, a data processing system includes a processor, and a memory coupled to the processor. The memory includes a CAD module stored in the form of machine-readable instructions and executable by the processor. The CAD module is configured to obtain logical definition data of a piping system with one or more pipe runs, and compute a piping path for each pipe run based on the logical definition data of the piping system. The CAD module is configured to determine positions of the one or more piping components for said each pipe run based on the computed piping path for said each pipe run, and associate the one or more piping components for said each pipe run with the determined positions of the one or more piping components. Moreover, the CAD module is configured to automatically generate a graphical model of the piping system based on the association of the one or more piping components with the determined positions for said each pipe run.
In yet another aspect, a non-transitory computer-readable storage medium, having machine-readable instructions stored therein, which when executed by a data processing system, causes the data processing system to perform method steps described above.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the following description. It is not intended to identify features or essential features of the claimed subject matter. Furthermore, the claimed subject matter is not limited to implementations that solve any or all disadvantages noted in any part of this disclosure.

The logical definition processing module 202 is configured to obtain and interpret logical definition data of a piping system from the CAD database 116. The piping system includes one or more pipe runs. Each of the pipe runs contains piping components such as pipes, valves, etc. and connects a source equipment (e.g., a pump) and target equipment (e.g., tank). The logical definition data of the piping system includes piping components information and information associated with connections between different piping components in each pipe run of the piping system. The piping component information may indicate equipment to which pipes are to be connected, pipe specification, bend radius, insulation information, valves, and other instrumentation with sequence information. The information associated with connections indicates connection points at equipment between which pipes are to be connected.
In some embodiments, the logical definition processing module 202 is configured to determine a graphical state of the piping system by comparing with the logical definition data if a graphical model of the piping system exists. That is, the logical definition processing module 202 determines whether the graphical model of the piping system is partially complete so that the graphical model can be automatically completed. This eliminates a need to redesign the entire piping system when the partially complete graphical model of the piping system is available.
The piping path module 204 is configured to compute piping path for each pipe run in the piping system based on the logical definition data of the piping system. For example, the piping path module 204 creates a series of segments connecting first equipment and second equipment. The position computation module 206 is configured to determine pipe size and bend/elbow for each pipe run based on the logical definition data of the piping system. Furthermore, the position computation module 206 is configured to determine positions of piping components required for designing said each pipe run along the series of segments in the computed piping path. In an embodiment, the position computation module 206 is configured to compare the desired dimension of a piping component (e.g., width of a valve) along an axis of the selected pipe run with length of a first available segment in the computed piping path. The position computation module 206 is configured to determine whether the length of the first segment is greater than the desired dimension of the piping component. The amount by which the length of the first segment shall be greater than the desired dimension of the piping component is pre-defined. Then, the position computation module 206 computes a point on the first segment at a length equal to the desired dimension of the piping component. The computed point indicates the probable position of the piping component in the pipe run. It can be noted that the positions of the piping components are determined with respect to geometric coordinates within a three-dimensional space along the computed piping path.
The placement module 208 is configured to associate the piping components associated with said each pipe run with the determined positions of the piping components in a particular sequence defined in the logical definition data. For example, each piping component is associated with the computed point on the respective segment such that the center point of the piping component coincides with the computed point on the respective segment. For instance, a pipe of a particular size is automatically linked to a set of geometric coordinates associated with the computed point in the three-dimensional space. The placement module 208 is also configured to add piping accessories to the piping components for said each pipe run. For example, if a flanged valve is used, appropriate flanges are linked to the flanged value along the pipe run. The placement module 208 is configured to add insulation, heat treatment specifications, color, nozzles, flanges, and other instrumentation to the pipe run as indicated in the logical definition data.
The graphical model generation module 210 is configured to generate a graphical model of the piping system. In one embodiment, the graphical model of the piping system is a three-dimensional CAD model of the piping system. The validation module 212 is configured to validate the graphical model of the piping system with respect to the logical definition data. For example, the validation module 212 is configured to determine whether the graphical model is consistent with the logical definition data and refine the graphical model based on validation errors. The output module 214 is configured to visualize the graphical model of the piping system on the display unit 110. The spool drawing generation module 216 is configured to generate a piping isometric spool drawing based on the graphical model of the piping system.
At step 306, positions of piping components for said each pipe run are determined based on the computed piping path. In one exemplary implementation, a piping component from the piping components for the pipe run is selected. A segment in the series of segments in which placement of the piping component is required is determined. For example, each segment is traced in the sequential order to determine whether there is a need to position the selected piping component in any of the segments. Initially, a first segment associated with the first connection point is selected. For example, the first segment is a segment which has a length longer than a length required for positioning the piping component. The length required for positioning the piping component may include additional pipe length on either side of the piping component. If the piping component has multiple ports, then the distance between opposing ports is considered as the length of the piping component.
Then, it is determined whether there exists a possibility for positioning the selected piping components in the first segment. If there is no possibility to position the piping component in the first segment, a next segment in the sequential order is selected and a possibility to position the piping component is determined. In this manner, each of the segments is traced in the sequential order. If there exists a possibility to position the piping components in the first segment, then position of the piping component in the first segment is computed. The position of the piping component along the first segment is computed with respect to geometric coordinates in a three-dimensional space along the computed piping path. Thereafter, a next piping component in the list of piping components is selected, and the above steps are repeated. In this manner, positions of the piping components of the pipe run are determined along the computed piping path.
At step 308, the piping components for said each pipe run are associated with the determined positions of the piping components. For example, the piping components required for designing the piping system are selected from a list of piping components based on the logical definition data. Each of the piping components of particular specification (e.g., number, size, material, etc.) is linked with the corresponding position determined in step 306.
At step 310, a graphical model of the piping system is automatically generated based on the association of the piping components with the positions of the piping components. At step 312, the generated graphical model of the piping system is output on the display unit 110. The generated graphical model of the piping system is visualized as a three-dimensional model on the display unit 110. A three dimensional model of piping system 802 automatically generated by the data processing system 100 using logical definition data is depicted in
At step 408, a plurality of piping paths for the selected pipe run is computed. For example, the piping paths are created from the first connection point to the second connection point. Each piping path includes a series of linear segment. At step 410, an optimal piping path is determined from the plurality of piping paths based on predefined criteria. It can be noted that the optimal path is determined using routing algorithms well known in the art.
At step 412, pipe size and bends/elbows associated with the pipe run are selected using the piping component information. In one embodiment, the piping component information indicates pipe size information and bend radius definition corresponding to the pipe size information. In this embodiment, the pipe size and bends/elbows are selected based on the pipe size information and corresponding bend radius definition.
At step 414, positions of piping components are determined based on the optimal piping path. For example, the positions of the piping components are determined with respect to geometric coordinates in three dimensional space. At step 416, each of the piping components is associated with the determined positions of the piping components. For example, each of the piping components are mapped to the geometric coordinates in the three dimensional space.
At step 418, it is determined whether additional piping components are to be associated with any of the piping components. If additional piping components are to be associated, then at step 420, the additional piping components are associated with respective piping components and the step 422 is performed. For example, flanges are associated with flange valves present in the pipe run. If no additional piping components are to be associated, then at step 422, it is determined whether any nozzles are to be associated with the piping components. If nozzles are to be associated with the piping components, then at step 424, nozzles are associated with the respective piping components. If no nozzles are to be associated, then at step 426, flanges are associated at the appropriate locations in the pipe run. At step 428, insulation and color information is applied to the piping components. At step 430, the pipe run is validated.
At step 432, it is determined whether the pipe run is validated successfully. If the pipe run is validated successfully, then at step 434, it is determined whether any pipe run is remaining in the plurality of pipe runs. If all pipe runs are designed, then at step 436, a graphical model of the piping system is generated. If one or more pipe runs are remaining, then step 404 is repeated.
At step 510, a pipe run is selected from a plurality of pipe runs in the piping system. At step 512, a first connection point and a second connection point associated with the selected pipe run is determined. At step 514, a plurality of piping paths for the selected pipe run is computed. At step 516, an optimal piping path is determined from the plurality of piping paths based on predefined criteria. At step 518, pipe size and bends/elbows associated with the pipe run are selected using the piping component information.
At step 520, positions of piping components are determined based on the optimal piping path. At step 522, each of the piping components is associated with the respective positions of the piping components. At step 524, it is determined whether additional piping components are to be associated with any of the piping components. If additional piping components are to be associated, then at step 526, the additional piping components are associated with respective piping components and the step 528 is performed. If no additional piping components are to be associated, then at step 528, it is determined whether any nozzles are to be associated with the piping components. If nozzles are to be associated with the piping components, then at step 530, nozzles are associated with the respective piping components. If no nozzles are to be associated, then at step 532, flanges are associated at the appropriate locations in the pipe run. At step 534, insulation and color information is applied to the piping components. At step 536, the pipe run is validated.
At step 538, it is determined whether the pipe run is validated successfully. If the pipe run is not successfully validated, then at step 544, validation errors are resolved and the step 536 is repeated. If the pipe run is validated successfully, then at step 540, it is determined whether any pipe run is remaining in the plurality of pipe runs. If all pipe runs are designed, then at step 542, a complete graphical model of the piping system is generated. If one or more pipe runs are remaining, then step 510 is repeated.
