<p><P>PROBLEM TO BE SOLVED: To provide an anomaly diagnostic apparatus capable of reducing maintenance/management costs by reducing the frequency of disassembly/assembly work, which requires time and labor. <P>SOLUTION: The anomaly diagnostic apparatus for diagnosing the presence or absence of anomalies in a bearing device for an axle of a rolling stock is provided with a detection processing part for outputting a signal generated by the bearing device as an electric signal; an arithmetic processing part for diagnosing anomalies of the bearing device on the basis of the output of the detection processing part; a result output part for outputting determination results by the arithmetic processing part; and a control processing part 40 for feeding back a control signal to a control system of the rolling stock on the basis of the determination results. Since the presence or absence of anomalies caused by wear and breakage of components of a sliding member by analyzing the output of a sensor of a bearing with the sensor incorporated in the bearing device of the rolling stock by the arithmetic processing part 30 as an information processing device and performing comparison with reference data in the anomaly diagnostic apparatus, it is possible to determine anomalies without disassembling the rolling stock and its bearing devices as in a normal state of use. Therefore, it is possible to reduce maintenance/management costs by reducing the frequency of disassembly/assembly work, which requires time and labor. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
