Abstract
Description
Technical Field
[0001] The present invention belongs to the field of railway optical cable concealed engineering management, and in particular relates to a solution for managing railway optical cable concealed engineering based on GIS technology. Background Art
[0002] Optical cables are a crucial medium for transmitting information between indoor and outdoor equipment in railway signaling systems and are a vital component of station equipment. Once buried, determining cable location, layout, and parameters requires consulting numerous drawings, a time-consuming and labor-intensive process, especially during rainy weather. Furthermore, maintenance is significantly hindered by changes in maintenance personnel, line modifications, and the loss or damage of construction drawings. Therefore, a comprehensive and standardized management system is urgently needed to ensure the safe and stable operation of optical cables. Summary of the Invention
[0003] The present invention intends to establish a solution for the management of concealed railway optical cable projects. By using high-precision positioning equipment in conjunction with self-developed acquisition software, the concealed engineering information of railway optical cables, such as ground equipment, underground optical cable paths, key points, etc., is collected. The collected information is drawn into drawings that meet GIS technical specifications. The drawings are loaded and displayed using a map engine or directly used to achieve the purpose of managing the concealed railway optical cable project information.
[0004] In order to achieve the above purpose, the present invention adopts the following scheme: A scheme for managing railway optical cable concealment engineering based on GIS technology includes: High-precision positioning equipment: Terminal equipment with differential positioning accuracy of sub-meter or above, and a screen for human-computer interaction; Self-developed acquisition software: Installed in high-precision positioning equipment, it enables railway optical cables to collect on-site coordinates of equipment, boxes, cable directions, trench directions, aisle directions, reference lines, and other information that needs to be collected. Other ancillary attribute information is input and classified and managed within the software; after the collection is completed, the collected information table is exported; GIS drawing: The data derived from the above collection is used for graphic drawing through professional CAD software to draw track lines, cable trench directions, aisle locations, reference lines and other information. Finally, GIS software is used to process the data, add text annotations, graphic elements, coordinate systems and other information, and generate scale drawings according to GIS technical specifications. Furthermore, the contents of the drawings include, but are not limited to, drawing track lines, cable trench directions, aisle locations, reference lines and other information, but are limited to the scope of railway optical cable management; Furthermore, the drawings are used on, including but not limited to, mobile terminal platforms and web-based management platforms; Furthermore, the drawings are developed specifically for information management of concealed railway optical cable projects; Compared with the existing technology, the present invention has the following technical effects and advantages: The present invention uses GIS technology to display and manage railway optical cable concealed engineering information, greatly facilitating on-site railway optical cable management, reducing reliance on traditional drawings and the difficulty of interpreting drawings, and improving the efficiency and accuracy of on-site location search for target locations. Furthermore, a method is provided to display the optical cable concealed engineering information based on geographical location, and the information display is simple and intuitive; The GIS technology solution provided by the present invention for managing concealed railway optical cable projects has extremely high accuracy and applicability. The hierarchical control of GIS layers improves display flexibility, and GIS information also lays a data foundation for subsequent management. The GIS technology solution for managing concealed railway optical cable projects provided by the present invention can be used offline in a map engine without the need for an internet connection, ensuring data security. The drawings drawn are completely based on data and vector graphics, with no restrictions on scaling, no distortion, and minimal storage space requirements. BRIEF DESCRIPTION OF THE DRAWINGS
