Embodiment Construction

[0054] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0055] At present, in the prior art, foreign objects on railway lines are generally detected through contact or non-contact detection systems. However, the detection scale of existing contact or non-contact detection systems is relatively single, and only local The information obtained by the detection and detection is not comprehensive enough, and the practicability is poor. Based o...

Abstract

The invention provides a railway line foreign matter identification method and system. The system comprises a static air-staying platform, a dynamic air-staying platform, multiple monitoring devices and a foreign matter identification device, wherein the static air-staying platform processes obtained first image information to obtain a first group of railway line data, the dynamic air-staying platform processes obtained second image information to obtain a second group of railway line data, the multiple monitoring devices process obtained third image information of a railway line to obtain a third group of railway line data, the foreign matter identification device is connected to the static air-staying platform, the dynamic air-staying platform, and the multiple monitoring devices respectively, whether a foreign matter exits in the railway line or not is judged according to any group of the railway line data, and if it is judged that the foreign matters exists, fusion processing is conducted on at least two groups of the railway line data in the railway line data to obtain a first processing result and generate an alarming signal. The railway line foreign matter identification system is diversified in detection dimension and can achieve omnibearing detection; meanwhile, the foreign matter information obtained after processing is more comprehensive, and thus the technical problems in the prior art that the detection dimension is single and the obtained information is not comprehensive enough are solved.

Description

technical field [0001] The invention relates to the technical field of rail transit operation and comprehensive safety assurance, in particular to a method and system for identifying foreign objects in railway lines. Background technique [0002] At present, my country's railway construction is increasing day by day. During the construction of new railways crossing or adjacent to existing lines, machinery, equipment, personnel and construction materials often intrude into the boundaries of existing lines, resulting in great safety for the safe operation of existing lines. hidden danger. At the same time, in mountainous areas and tunnel entrances and exits, there are often sudden hazards such as rockfall, which seriously threatens the safety of railway transportation. Therefore, accurate and timely identification of foreign objects on high-speed railway lines is the key to ensuring the safe operation of rail transit. [0003] In the prior art, foreign object detection method...
