  • 3D Machine Vision System for Inspection of Contact Strips in Railway Vehicle Current Collectors
    Publication

    Construction and technical condition of current collectors is crucial to reliability and safety of railway transportation. According to the Technical Specifications for Interoperability railway vehicles in the European Union should be equipped with carbon contact strips. Excessive wear or defects of contact strips degrade the capability of undisturbed power transmission, cause faster wear of contact wire, and can even result in...

  • Algorithm for Automatic Wear Estimation of Railway Contact Strips Based on 3D Scanning Results
    Publication

    Electric rail vehicles use current collection system which consists of overhead contact line and a current collector (pantograph) mounted on the roof of a vehicle. A pantograph is equipped with contact strips, which slide along the contact wire, ensuring steady electric contact. Contact strips are made of carbon layer, fixed to an aluminum carrier. The carbon layer wears down due to friction. Using overly worn contact strips increases...

  • Analiza wymagań sprzętowych dla bezkontaktowego system pomiaru położenia przewodu jezdnego sieci trakcyjnej do celów diagnostycznych
    Publication

    - Logistyka - Year 2014

    Zwiększanie mocy pojazdów trakcyjnych oraz podnoszenie ich prędkości sprawia, że rosną wymagania techniczne jakie musi spełniać sieć trakcyjna jezdna. Można tutaj wymienić zarówno te związane z koniecznością dostarczenia odpowiedniej mocy do pojazdu, jak i wymagania związane z parametrami geometrycznymi samej sieci. Zapewnienie właściwej geometrii sieci jezdnej jest ściśle powiązane z pojęciem jej diagnostyki technicznej. Wśród...

  • Analiza wyników monitoringu odbieraków prądu w warunkach ruchowych na linii kolejowej
    Publication

    - Year 2014

    Omówiono metodę ciągłego monitorowania stanu odbieraków prądu na linii kolejowej w oparciu o pomiar uniesienia przewodów jezdnych sieci trakcyjnej w czasie przejazdu pociągu. Omówiono zasadę działania wdrożonego stanowiska monitoringu. Opisano algorytmy analizy danych pomiarowych - w szczególności oszacowania siły statycznej odbieraka prądu - i przyjęte kryteria oceny odbieraka. W analizie bierze się pod uwagę także prędkość pociągu...

  • A Visual Method of Measuring Railway-Track Weed Infestation Level
    Publication

    This paper concerns the assessment of railway track surface conditions in relation to the degree of weed infestation. The paper conceptually describes the proposed method using a visual system to analyse weed infestation level. The use of image analysis software for weed detection is also proposed. This new measurement method allows for a mobile assessment of the track’s weed infestation status. Validation of the assessment method...

  • Application of Traction Supply System for Charging Electric Cars
    Publication

    - ENERGIES - Year 2022

    The development of electromobility involves the development of electric cars charging infrastructure. The increase of the number of chargers poses new demands for the AC power grid, especially in regard to its capacity of delivering high peak power. As an alternative for the public AC power grid, urban electrified transportation systems (trams, trolleybuses, and metro) can be used for supplying electric cars chargers. The article...

  • Analysis of inductive power transfer systems for variable air gap and voltage supply frequency
    Publication

    - Year 2011

    The paper describes an IPT system, by which electrical energy may be transmitted through a large air gap between coils without electrical connection. It presents theoretical and simulation analysis of IPT, which allows for supplying a receiver in the conditions of slow, in relation to the dynamics of power supply, changes in dimension of the air gap. The influence of frequency characteristics of the system on the possible selection...
