Sensor based means for monitoring the mechanical condition of intermittently operated rotating machinery

摘要

A method for monitoring the mechanical condition of a machine, wherein periods of stable operation are automatically detected by a characteristic signal in combination with predetermined time periods, the predetermined periods comprising a delay period, wherein statistically significant measurements are taken on the characteristic signal over a period of time Interruptions and variations in the operation of the machine may result in uncharacteristic signals, and the processing of a signal describing operation of the machine during the statistically significant measurement automatically excludes those portions of the signal associated with interrupts and variations in the operation of the machine are.
