“…In general, the irregularity of the contact wire and faults of the catenary system come from many different factors, such as expansion joint defects, overlap defects, and steady arm defects. ese catenary defects may induce hard impacts on the dynamic interaction, which result in not only mechanical damage to the pantograph and local abnormal wear of the contact wire, but also the failure of the pantograph-catenary system and a reduction in its service life [23][24][25][26]. us, it is necessary to facilitate an effective monitoring scheme and an accurate diagnostic method to locate the defects and diagnose breakdowns for the safe operation of the train.…”

In recent years, the length of electrified railway systems has increased along with the number of railway vehicles in China. For the pantograph-catenary system, as one of the key components of the vehicle system, an urgent problem includes diagnosing faults and proposing a safety monitoring system to assure safe operation, improve the level of detection, and decrease the cost of maintenance and repairs. For the monitoring system based on the pantograph, the design process, whole architecture, function module, fault diagnosis method, and monitoring scheme have been investigated. Two specified faults were introduced to describe how to develop such a monitoring scheme based on the pantograph condition-based recognition.

“…The FE technique is the most widely used to model high-speed railway catenaries as can be seen from the review [26] and references in [14]. The catenary is mainly composed of a messenger wire, a contact wire, registration arms, droppers and some typologies also have stitch wires as can be seen in Fig.…”

The quality of current collection becomes a limiting factor when the aim is to increase the speed of the present railway systems. In this work an attempt is made to improve current collection quality optimising catenary geometry by means of a Genetic Algorithm. As dropper lengths and dropper spacing are thought to be highly influential parameters they were chosen as the optimisation variables. The results obtained show that a Genetic Algorithm can be used to optimise catenary geometry to improve current collection quality measured in terms of the standard deviation of the contact force. Furthermore, it is highlighted that apart from the usual pre-sag, other geometric parameters should also be taken into account when designing railway catenaries.

tr 2, 3, 4Özetçe-Bu çalışmada elektrikli trenlerde kullanılan pantograf türünün belirlenmesi için model tabanlı bir yaklaşım önerilmektedir. Elektrikli trenlerin kullanım şartlarına göre pantograf katener sistemin yapısı değişmektedir. Pantograf katener sistemlerinden alınan görüntüler kullanılarak pantograf sisteminin geometrik modeli oluşturulmaktadır. Oluşturulan modelin hangi tür pantografa ait olduğu tespit edilmektedir. İlk olarak kenar çıkarımı ve Hough dönüşümü ile pantografta bulunan bütün doğrular tespit edilmektedir. Tespit edilen doğrulardan alınan bazı bilgiler bulanık mantık işleminde kullanılarak pantografın türü belirlenmektedir. Pantograf türünün belirlenmesi pantografın yüksekliğini tahmin etmek ve katener ile pantograf arasındaki temas noktasını analiz etmek için uygundur. Böylece ark oluşumu ve aşırı temas kuvveti gibi temas noktası problemleri tespit edilebilecektir. Anahtar Kelimeler -pantograf katenersistemler; görüntü işleme; bulanık mantık; modelleme.Abstract-In this study, a model based approach is proposed for the recognition of the pantograph type used in electric trains. The shape of the pantograph-catenary changes according to usage conditions of electric trains. A geometric model of the pantograph is constructed by using images taken from the pantograph-catenary system. The pantograph type is determined by using the constructed model. First, all straight lines are extracted from the image by applying the edge detection and Hough transform to the image. Some knowledge obtained from straight lines are given to fuzzy logic and type of pantograph is determined. The determination of pantograph type is useful to estimate the pantograph height and to analyze of contact point between pantograph and catenary. Therefore, contact point problems such as arcing and excessive contact force can be detected.
