Raylı sistemlerde yolculugun sorunsuz tamamla-nabilmesi için sistem bütünlüğü kritik öneme sahiptir. Sistem bütünlüğü, lokomotif ve vagonlar haricinde katener (yüksek gerilim) hattı, pantograf ve raylara bağlıdır. Katener hattı ve pantograf, lokomotife elektrik iletimini sağlarken rayların seviyesi pantografın elektrik hattına düzenli temasına etki eder. Raylarda oluşabilecek çöküntüler katener hattı ile pantograf arasında ark (kıvılcım) oluşumuna neden olur. Katener hattının pantograf sınırları dışına çıkması, pantografta oluşabilecek çentikler ve ark oluşumu lokomotif üzerinden anlık izlenebilir. Bu çalışmada amacımız, bu üç ögeden kaynaklanabilecek hataları kameralı bir sistemle, gerçek zamanlı ve otomatik izleyerek tren yolculuğunun güvenli ve kesintisiz yapılmasına katkıda bulunmaktır. System integrity is critical for completion of journey in rail transport systems. System integrity is dependent on the catenary line, pantograph and the train tracks in addition to the locomotive and the wagons. Catenary line and pantograph are the main devices for transmission of electricity to the locomotive. The level of tracks has a direct influence on the continuity of conduction between the catenary line and the pantograph. Settling of tracks momentarily separates the conduction devices, resulting in arcs. In this study we aim to detect catenary line, pantograph and track related problems automatically and in real time for safety of railroad transportation.
