Analysis of ZPW-2000A track circuit equipment maintenance based FMEA
Abstract: ZPW-2000A track circuit is made by the optimized transmission system parameters and more comprehensive security technology track circuit transmission structure, it is a major device in Chinese railway signal system. Now, it is widely used major passenger rail lines. Its performance directly determines the security and the stability of railway transportation, when device is in failure, maintenance analysis is an important means to improve equipment reliability and availability.
In this paper, it is to start from the track circuit composed ZPW-2000A departure , base on its use of Potential Failure Mode and Effects Analysis (Failure Mode and Effects Analysis, FMEA) methods for maintenance analysis after the failure of equipment, and using the system FMEA and FMEA equipment combining failure modes and effects analysis for the device.
First, we should konw the current situation and the development trend of failure modes and effects analysis and ZPW-2000A track circuit in domestic and foreign, understand the meaning and the function of failure modes and effects analysis, definite failure modes and effects analysis mission and show the various benefits brought from failure modes and effects analysis,master implementation procedures and core use of failure modes and effects analysis.In summary, this provides e a theoretical basis to research ZPW-2000A track circuit equipment.
Secondly, it analyzes the structure of ZPW-2000A track circuit, understands the function of each subsystem and relationships, so that we can establish the reliability block diagram and function block diagram of the system, use equipment FMEA and system FMEA to analyze the device. we may occur each sub-clear device failure Mode and severity of system failures, by calculating the value of its risk priority, it gives RPN severity of each fault repair proposed measures and preliminary analysis of fault repair.
Finally, the paper summarizes the research results, finds insufficient research, gives prospects.
