It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The first embodiment is as follows:
as shown in fig. 1, a schematic flow chart of a ship pipeline agility design method in an embodiment of the present invention is shown, which mainly includes steps S1 to S5.
Step S1: the start and stop position of the input pipe arrangement.
In some examples, the starting and stopping positions can be determined by clicking, and the starting and stopping positions are determined by automatically acquiring the distribution points on the equipment and the pipeline; alternatively, the start-stop position of the line arrangement can also be determined by means of a manual input.
Step S2: and calling the design specification information of the pipeline.
In some examples, the ship pipeline design specification knowledge base may be created first, that is, the ship pipeline design specification knowledge may be combed, and the international standards, the industry standards, the enterprise standards, and the design experience knowledge of designers used in the ship pipeline production design may be summarized and collated to form the pipeline layout design specification knowledge base. After the ship pipeline design specification knowledge base is established, pipeline arrangement rules in the knowledge base can be automatically called when pipeline agile design is executed, and the called pipeline arrangement rules are transmitted to a pipeline intelligent design system for realizing intelligent planning calculation of pipeline paths.
Step S3: and executing automatic pipeline arrangement and generating a pipeline arrangement scheme.
Particularly, the pipeline layout design is agile, namely, the pipeline starting and stopping positions are appointed in the pipeline design process, pipeline attribute data and the like, multiple pipeline layout schemes such as reasonable design, minimum material consumption, lowest processing cost and best maintainability are automatically generated, designers only need to select the optimal layout scheme according to actual requirements without relying on a manual pipe layout mode, the problems of pipeline layout design rationality, material consumption, processing cost, maintainability and the like do not need to be judged and intervened manually, and the pipeline layout design is more accurate and human errors are effectively reduced.
The principle of the pipeline arrangement is shown in fig. 2, and specifically includes arrangements S31 to S34.
Step S31: reading model data; the read model data comprises pipeline model selection data, pipeline information data, occupation data of each professional model, start-stop coordinate data and the like.
Step S32: reading design specification knowledge; the read design specification knowledge includes matching rule types, reading design constraints, reading evaluation indexes, and the like.
Step S33: designing a pipeline path, executing path planning calculation, acquiring a design block envelope of pipeline arrangement, calculating space occupation of other models such as a ship body, equipment and accessories in the block envelope, calculating the pipeline arrangement trend, and calculating the pipeline arrangement path and passing points by combining a Dijkstra algorithm and an optimal priority search algorithm. The principle of Dijkstra algorithm is to find the shortest distance from the starting point to all the points, and then relax once to find the shortest distance, so that the shortest distance from the starting point to all the other points is found after all the points are traversed, the points with the shortest distance just found are used as transfer stations and cannot be closer, and if the shortest distance is found, the distances are updated, so that the shortest distances from the starting point to all the other points are stored after all the points are traversed.
Step S34: and outputting the pipeline layout model.
Step S4: and obtaining a judgment result whether the pipeline arrangement scheme is reasonable.
It is worth to be noted that, aiming at the selectable pipeline arrangement scheme generated by automatic arrangement, the generated pipeline arrangement scheme can be manually selected and judged whether to be reasonable or not; if the scheme is reasonable, selecting a proper management arrangement scheme; if the scheme is not reasonable, analyzing the reason of unreasonable; the results of the analysis may be entered into the system by an analyst. The analysis process of the reason for unreasonable analysis scheme can push design knowledge for designers as required through knowledge service in the knowledge base, assist the designers to quickly and accurately find the required knowledge, and finally maintain the knowledge base and regenerate the arrangement scheme.
Step S5: and generating a pipeline arrangement model to finish automatic arrangement of the pipeline. Specifically, the optimal pipeline arrangement scheme can be selected according to the generated pipeline arrangement scheme, and the three-dimensional modeling design of the pipeline is completed.
It should be understood that the agile design method for ship pipelines of this embodiment can be applied to controllers, such as arm (advanced RISC machines) controllers, fpga (field Programmable Gate array) controllers, soc (system on chip) controllers, dsp (digital Signal processing) controllers, or mcu (micro controller unit) controllers; the method can also be applied to Personal computers such as desktop computers, notebook computers, tablet computers, smart phones, smart televisions, Personal Digital assistants (Personal Digital assistants, short for PDAs) and the like; the method can also be applied to servers which can be arranged on one or more entity servers according to various factors such as functions, loads and the like, and can also be formed by distributed or centralized server clusters.
