FAILURE MODE AND EFFECT ANALYSIS FOR SYSTEM SAFETY ASSURANCE OF ELECTRONIC CONTROLS
The need to achieve the highest levels of train safety while offering fast service with short headways leads to specification of automatic train control (ATC) as a major subsystem of rapid transit operations. Specifications recognize potential consequences of malfunction on quality of service and safety. The automatic train protection function of the ATC system must not only have acceptable failure rates but any failures which do occur must not degrade safety. The author discusses analyses of the fail-safe function: Failure mode and effect analysis (FMEA) as applied to electronics, electrical/electronic safety analysis. The way in which General Railway Signal applies these methods is described.
