Design And Implementation Of Optimal System Of The Existing Railway Adjusting

The optimal design of the existing railway adjusting is an important way to ensure the safety,stability and comfort of railway trains.With the vigorous development of rail transit industry in China,the operating mileage has been growing,which undoubtedly increases the transportation load of the existing railway lines.and higher requirements on railway operation.Compared with the rapid expansion of railway lines and the improvement of surveying and mapping technology,the automation level of railway business is still relatively weak,which makes it necessary to accelerate the digital transformation of related businesses and keep up with the trend of informationization.This thesis mainly studies the optimal design of the existing railway adjusting.Based on theoretical methods,business processes and previous professional tools software usage,the reasonable analysis and design will be made,a fully functional tool that can be used for this business and will be developed to improve the efficiency.According to the related projects and business requirements of China Railway First Survery And Design Institute(CR-FSDI),the software will be developed and integrated based on the AutoCAD,aiming at improving the intelligent degree of computerization of the tasks of optimal design of the existing railway adjusting,and is compatible with the railway point cloud information extraction system in the project.Therefore this thesis mainly finalized the following tasks:Firstly,the relevant theoretical basis,project background and related technologies have been investigated and analyzed in detail,including the principles,methods,business processes of the optimal design of existing railway adjusting system,the technical points related to the secondary development of AutoCAD and the concept of domain-driven design(DDD)in system modeling.Then,according to the relevant business requirements,the system modeling analysis and design will be discussed in detail based on the domain model established by DDD.The system architecture design and the design of the core business module will be carried out.The architecture design is divided into three layers: the domain layer is core,encapsulating the business logic and related algorithms;the application layer defines software tasks and the presentation layer provides the logic and view display function of human-computer interaction.The AutoCAD interaction module is independent of the presentation layer,which is easy to design and update.Finally,the software has been realized according to the system design.Considering the system scalability and maintainability,the sub-modules are implemented and the help documentation of the corresponding modules is provided.The software is verified by functionality to ensure the feasibility.The corresponding design specifications and operating manuals are compiled for review.
