The Microprocessor in Railway Control Systems

  • Satoru Sone
  • Ikumasa Okumura
Part of the International Series on Microprocessor-Based Systems Engineering book series (ISCA, volume 1)


Application of microprocessors in railway systems has been as promising as is seen in other fields. After mentioning the sound applications to monitoring on-board equipments, traffic control, passenger information systems, control at marshalling yards, etc., state-of-the-art technologies in this field will be described; on (i) energy saving operation of intercity trains, (ii) interference-free ac motor drive system and (iii) microcomputerised realisation of fail-safe vital functions of signalling system. Functions of (i) and (ii) would not have been realised without using microprocessors and that of (iii) has been thought realisable only by using non-electronic fale-safe devices such as gravity-operated electromagnetic relays. Sections 1.3 and 2.3 are authored by Dr.Okumura and the rest by Dr.Sone.
