Somasundaram Nellai B.S (Eng Tech), MS (IM), MIET, AMIRSEAnsaldo STS Australia Pty LtdAnthony Stephen Lusty BE (Electrical), GDip Railway Signalling, MIRSEAnsaldo STS Australia Pty LtdThe introduction of Processor Based Interlockings (PBIs) to the railway network has led to the requirement for vital serial data communication between distributed PBIs. Traditionally, vital serial data has been carried via closed/hardwired communication systems (eg copper or Fibre Optic), which often involve significant installation costs. The Ansaldo STS developed Microlok Vital link over Radio (MVR) provides an efficient and cost effective alternative. The MVR is a point to point, open transmission communication system, which transports vital serial data between distributed PBI applications in low to medium density railway networks. The MVR has been specifically developed to meet the requirements of conventional vital communication, addressing all the requirements for the safe communication of vital data. The paper outlines the system concept, the development process, challenges, independent safety validation and successful implementation of new MVR systems in rail networks. |
