Safety and Reliability of Speed Detection and Location Systems for High-Speed Maglev Trains

Through redundant fault-tolerant technologies, this study aimed to enhance reliability in the aspects of data collection and processing for train positioning systems systematically. The authors conduct safety analysis of the relative positioning module and absolute positioning module in high-speed maglev train positioning systems via the THR and SIL safety analysis methods. The study obtains the SIL level of each module and analyzes the event risks. The corresponding improvements are proposed to reduce the hazard degree and dangerous possibilities of risky events.
