Convergência Tecnológica para Redes Ethernet em Sistemas de Controle de Processo em Ferrovias
(Instituto de Tecnologia, 2018) BORBA, Felipe Colares de; Kleber Bittencourt Oliveira
The main objective of this dissertation is to study the changes in the telecommunications field that railroads must face to avoid technological obsolescence in their automation, particularly railway signaling. The study focuses on the technological convergence to Ethernet interfaces. A literature review was conducted, followed by an analysis of the convergent technology (Ethernet) and the converged technology (RS-232). After these theoretical considerations, an Ethernet system topology was proposed for a hypothetical railway and implemented through a test setup. Tests were simulated using the standard reference protocol RFC 2455 to assess the capacity of the suggested Ethernet topology for railway applications. The practical results confirmed that the proposed topology meets all the necessary parameters for a telecommunications network supporting a railway signaling system. The conclusion is that railways can base their telecommunications systems on Ethernet technology while coexisting with legacy systems during the migration phase.
