Technical Field

[0001] The present invention relates to the technical field of generating a railway optical cable path map, and more specifically, to a method for generating a railway optical cable path map. Background Art

[0002] Railway optical cables are important basic equipment to ensure railway driving safety. At present, the optical cables of conventional railways are laid by direct burial, overhead and pipeline, and most of them are laid by trenching and direct burial. At the same time, there are the following problems: 1. Since the design drawings of railway optical cables are schematic diagrams, and there are situations where the design may be changed during the construction process; 2. Due to the long-term lack of unified management of optical cable technical drawings, the data is inaccurate; During the construction of existing railway lines, due to inaccurate judgment of the optical cable path, optical cables are often dug up and damaged, which has a great impact on railway transportation efficiency and driving safety. Therefore, the railway operation and maintenance management department needs an accurate and complete optical cable path plan. The existing optical cable path map is basically drawn and marked manually, and its main reference is the design drawings. It is not accurate enough and has poor usability. At the same time, the workload of drawing the optical cable path map is large.

[0003] Therefore, we propose a method for generating railway optical cable route map to solve the above problems. Summary of the invention
