A generic fault detection and diagnosis approach for railway assets

摘要: This paper presents a generic approach for fault detection and diagnosis class of railway assets with common dynamic characteristics known as Single Throw Mechanical Equipment (STME). STMEs are widely used in systems, examples which include point machines, train-stops (also trip-cocks), train doors level crossing barriers. These case studies this paper. The methodology applying to an STME is based on model the equipment. To construct model, data collected from during laboratory experiments was analysed so that features could be identified. Based series incremental inputs, exponential characteristic observed throw time, activation delay trajectory profiles. As large nonlinear load generally moved when operated, dynamics therefore more important than their static parameters. A its application discussed
