development of railway Signaling system based on network technology
Systems Man and Cybernetics, 2005Co-Authors: Y Hirano, T Kato, T Kunifuji, T HattoriAbstract:Much Signaling equipment (e.g. Signals, switching devices) are installed along railway tracks, and these are working in cooperation with each other, referring to other Signaling equipment status. In today's railway Signaling system, this information is transmitted using Signal Cables. Owing to this installation of Signaling system itself, especially installation of Signal Cable, we have some problems on our conventional Signaling system. The problems are 1st "high cost for construction", 2nd "many faults from mistakes in Cable connection", and 3rd "much time for restoring when it has failed". To solve these problems we have developed a new Signaling system based on network technology, utilizing Ethernet-passive optical network (E-PON). In this paper, we introduce this system, and define the requirements for securing safety, availability and environmental resistance of this system. Then we describe concrete techniques for realizing the requirements

Enhancement of radiated noise suppression on flexible magnetic thick film electromagnetic interference filters with high-frequency permeability on data Signal Cable
Journal of Applied Physics, 2010Co-Authors: Kyung Sub Lee, In-ho Byun, In-bum Jeong, Sang-woo KimAbstract:Frequency-dependent impedance characteristics of flexible thick film EMI filters were investigated for enhanced suppression of high-frequency noise currents in the frequency range from several tens of megahertz to 1.5 GHz. The inductance of the rolled magnetic film filters was much lower than that of the conventional ferrite bead at lower frequencies but the inductance exceeded the level of the ferrite bead above 33–125 MHz because of the higher frequency dependence of real permeability. The enhanced impedance was mainly due to the increased inductance for the rolled thick film filters at lower frequencies of 210–550 MHz, depending on the complex permeability. The enhanced permeability at the higher frequency was attributed to the increased inductance and resistance of the rolled magnetic thick film filters. The higher frequency dependence of impedance was, the better the effect was reached to filter out the common-mode noise. It is found that the noise emission from a data Signal Cable is effectively sup...
