Abstract
The invention provides a steel rail damage determination method based on a convolutional neural network, and the method comprises the steps: carrying out the preprocessing of original multi-dimensional time sequence steel rail data, and outputting the current steel rail supporting position information after the analysis of the convolutional neural network; after the current steel rail supporting position information is compared with the historical steel rail supporting position information, the consistent supporting position information is marked as the same signal mark, and the abnormal supporting position information is marked as the abnormal signal mark; and carrying out steel rail artificial injury logic summary content and expert experience analysis on the abnormal supporting position information marked as the abnormal signal mark to obtain a steel rail suspected injury signal and current steel rail supporting position suspected injury information corresponding to the steel rail suspected injury signal. The determination system applying the method comprises a current steel rail supporting position information acquisition part, a supporting position information signal marking part and a steel rail suspected damage information analysis part. According to the invention, more accurate and rapid steel rail flaw information can be provided for steel rail flaw detection.
Description
technical field [0001] The invention relates to a rail damage determination method, in particular to a rail damage determination method and determination system based on a convolutional neural network. Background technique [0002] With the rapid development of road traffic, rails are the basis of railway operation to ensure the safe and reliable operation of trains, which is an important task in the daily maintenance of railways. The internal damage of the rail is the most important part of the rail damage, and it is also the part that requires more labor to ensure the safe operation of the rail. [0003] The common situation of manual flaw detection is the missed judgment and misjudgment caused by human unstable factors in the flaw detection process, resulting in the occurrence of rail breakage events, ranging from trains that cannot run normally in a short time, and endangering the lives and property safety of train personnel. . [0004] At present, the main form of man...
