Abstract: To meet the requirements of railway transportation management related application systems for the comprehensive utilization of graphical documents (referred to as files) after modeling railway stationary equipment, this paper designed a modeling software package for railway stationary equipment. The paper used eXtensible Markup Language (XML) to define graphic component (referred to as: graphic element) molds and file formats, which were used to abstractly describe the topological relationship structure and application properties of railway networks and train equipment along the line, designed file editors, graphic element mold designers, desktop application component libraries, and Web application component libraries to implement the drawing and display of drawings after device modeling functions such as interaction and device information extraction. At present, this software package is mainly used to draw signal layout plans, saving software procurement costs during application system integration.
