Research And Implementation Of Aided Decision System For Long Distance Aqueducts

Long-distance water pipeline project consisting of complex systems,continuous long line of complex terrain along the way,so that the water in order to ensure safety and reliability in the design requires various factors.The early design of the pipeline not only needs to take into account the safe operation of the water transmission project,but also requires rational design of the pipeline and pipe.In order to realize the decision-making of aided design of long-distance water transmission pipeline project,this paper based on the application of GIS in pipeline-aided design.According to the current hydraulic calculation and selection in the pipe section,the characteristics of pipeline data information and the main factors of pipe selection were analyzed.The tube selection process are studied and a hydraulic calculation model was established.Finally,the long distance pipeline auxiliary decision system was designed and implemented.Firstly,the application of GIS in long-distance water pipeline auxiliary design is described and the composition characteristics of long-distance water pipeline project are analyzed,the principle of pipeline selection and determination is described.An auxiliary pipeline design system based on ArcEngine secondary development component framework is implemented,and the idea of dividing the acquired pipeline data information using control points is proposed.Secondly,the influencing factors of pipe selection were analyzed,and the pipe selection process was clarified.The hydraulic calculation method for long-distance water pipelines was analyzed,and a hydraulic calculation model was established based on the pipeline data.In addition,the pressure checking method and checking process of the pipe segment are described.Based on the characteristics of pipeline data information,segment selection process and pipe segment hydraulic calculation model,the importance of the establishment of auxiliary decision-making system was expounded.According to the demand analysis,the functions of the auxiliary decision-making system are described.The basic framework of the auxiliary decision-making system,the overall business process and the sub-function business process are designed.Based on the requirements analysis and business process design of the auxiliary decision system,the Java language and JavaFx graphical interface package are selected,and the basic functions of the system are realized by combining the MySQL database.Cumbersome and complex hydraulic calculations are packaged to achieve a parametric human-computer interaction interface.In addition,the hydraulic calculation results were visually displayed to facilitate the use of personnel to assist in optimal design and simulation of working conditions.
