Enhanced rail component detection and consolidation for rail track inspection [PDF]
2012 IEEE Workshop on the Applications of Computer Vision (WACV), 2012 For safety purposes, railroad tracks need to be inspected on a regular basis for physical defects or design noncompliances. Such track defects and non-compliances, if not detected in a timely manner, may eventually lead to grave consequences such as train derailments.

Detection of Rail Defects Using NDT Methods
Sensors, 2023 The rapid development of high-speed and heavy-haul railways caused rapid rail defects and sudden failure. This requires more advanced rail inspection, i.e., real-time accurate identification and evaluation for rail defects. However, existing applications

Value of rescheduling of rail inspection [PDF]
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2018 A regular rail inspection schedule has been proposed to minimise any detrimental financial cost incurred due to operations under harsh environments. Missing opportunities to detect a defective rail could ultimately lead to its breaking, which would magnify the repair (as well as maintenance) cost by approximately 30–35% per rail-mile.

Improvement of autonomous railway monitoring robot prototype as fault detection on railway
Invotek: Jurnal Inovasi Vokasional dan Teknologi, 2021 One of the causes of accidents on trains to date has been caused by damage of railways such as cracked rails, broken rails and other rail defects. Currently, the inspection of the railway line is still carried out manually by the railway inspection ...

Elevator dynamic monitoring and early warning system based on machine learning algorithm
IET Networks, EarlyView., 2022 In order to monitor and warn the elevator dynamics, in this work, the machine learning algorithm is introduced, and the particle swarm algorithm is used to perfect the model. The model is optimised, and the experimental comparison shows that the optimisation of the model parameters can further improve the accuracy of the elevator load prediction. Then,

Big data framework for rail inspection
2017 International Artificial Intelligence and Data Processing Symposium (IDAP), 2017 It is necessary that periodical inspection and maintenance of railway transportation systems, which is becoming more and more common day by day, is required. A typical rail line can range from a few kilometers to thousands of kilometers. It is not possible to control this length of railway line with human labor.

Development of Rail Trajectory Measurement Device for Inspection of Crane Rail
International Journal of Automation Technology, 2012 In factories, an overhead crane is ordinarily used to convey heavy loads amounting to dozens of tons. However, the rails of the overhead crane face the risk of being deformed and cracking under heavy loads, and they are a cause of serious accidents.
