ZPW-2000A无绝缘移频轨道电路的RAM评估研究
Evaluation Research on the RAM of ZPW-2000A Jointless Audio Frequency-shift Modulated Track Circuit
摘要
Abstract
In order to evaluate the reliability,availability and maintainability (RAM) of ZPW-2000A Jointless Audio Frequency-shift Modulated Track Circuit,the block diagram of ZPW-2000A Jointless Audio Frequency-shift Modulated Track Circuit was constructed by top-down layer decomposition.Then the failure rate and repair rate of the smallest replaceable module or unit can be gotten by using the reliability prediction and maintainability prediction.Next,by using Markov model and reliability block diagram,the reliability indexes and maintainability indexes of ZPW-2000A Jointless Audio Frequency-shift Modulated Track Circuit can be obtained.Also the availability indexes of ZPW-2000A Jointless Audio Frequency-shift Modulated Track Circuit can be calculated according to the obtained reliability indexes and maintainability indexes.Finally,according to the obtained indexes,determine whether it can meet system requirements.关键词
