Analysis of urban rail ATP system maintenance
based FMEA
Abstract: Automatic Train Control System consist of Computer, communication, control technology and signal technology, and is of a high level automation. Automatic train protection system, also known as automatic train protection system, is an important part of urban rail train control system, it plays a very important role on trains’ running under the automatic control. It’s performance directly affects the efficiency and safety of chinese urban rail transportation, so reasonable and appropriate maintenance work needs to be done to ensure and improve the reliability and security of the urban rail Automatic train protection system.
In this thesis, Failure modes and effects analysis(FMEA) technical is applied to analyze the failure modes and effect of equipment maintenance in urban rail Automatic train protection system. And in this analysis, system FMEA and functional FMEA will be combined to analyze the failure modes and effect of equipment maintenance .
Firstly, clear the structure and function of urban rail Automatic train protection system, use the principles and procedures of failure mode and effect analysis to analyze urban rail Automatic train protection system of Shanghai Metro Line one. Identify the severity of the failure modes, the occurrence of failure and the detection of the reason.
Secondly, according to the Failure modes and effects analysis theory to calculate the risk priority order called RPN value. Give failure mode and effect analysis risk assessment of equipment maintenance. Then make recommended measures for the different failure modes based on the results of the Failure modes and effects analysis.
Finally, summarize the content of this study, identify the problems existed and directions for further research.
