| Abstract: | Track circuit is the key equipment of railway signalling systems,and its reliability is extremely important to ensure the safety of railway transportation.On the basis of FMEA theory,a FMEA analysis method for ZPW-2000A Jointless Audio Frequency-shift Modulated Track Circuit system is proposed.The corresponding FMEA content,the division rules of analysis level and failure criterions are defined according to the characteristics of track circuit system,and the confirming method of severity,occurrence and detection is also discussed,which is used to calculate the risk priority number （RPN ）.Based on the actual working condition of ZPW-2000A Jointless Audio Frequency-shift Modulated Track Circuit system,the FMEA analysis is conducted.The research indicates that the FMEA method can identify the potential hazards and the weak links which affect system reliability.It provides a practical method and theoretical basis for the reliability research of ZPW-2000A track circuit system. |
