Research purposes: Traditional railway line & station design software is highly dependent on specific graphics platforms, which limits the software's portability and independence, and is not conducive to the independent development of railway line & station design software. Therefore, this paper studies the architecture, geometry algorithms and third-party graphics platform decoupling mechanism of the geometry calculation kernel for line & station design, aiming to construct a geometry calculation kernel for railway line & station design independent of the graphics platform, allowing the business logic of station design to be decoupled from specific graphics platforms and adaptable to different operating systems and graphics platforms. This aims to enhance the autonomy of railway line & station design software development.
Research conclusions: (1) The geometry calculation kernel architecture proposed in this paper has strong scalability and high generality of core algorithms, which can meet various railway line & station design scenarios. (2) Compared with third-party graphics platforms, the geometry calculation kernel proposed in this paper has obvious advantages in railway line & station line support, drawing methods, calculation accuracy, calculation efficiency, and cross-platform migration. (3) Through the application in actual production projects, it is proved that the geometry calculation kernel can be used as the underlying kernel of line & station design software research and development. At the same time, through the expansion of the line definition layer, the geometry kernel construction method and related decoupling mechanism can also provide reference for the independent research and development of other linear engineering design software.
