Abstract

Door Control Unit (DCU) is one of the control equipment’s in Platform Screen Door (PSD) system which it’s safe operation have an important role in passenger safety on platform and Prevention of train delay in station. Maximum failure rate in doors control system is for DCU, so its failure analysis and reliability evaluation have special importance. In this article, DCU components for PSD system determined according to Tehran metro, firstly. Then Probable failures in DCU components reviewed by Preliminary Hazard Analysis (PHA) and applied necessary reforms. In next step, the block diagram structure for DCU offered by using selected components and failure analysis results. Finally, reliability by Reliability Block Diagram (RBD) and Safety Integrity Level (SIL) according to IEC61508 standard is calculated for circuit safety evaluation which leads to SIL3.
