A method of identifying a historical alert that is similar to an alert associated with a detected deviation from an operational state of a device includes receiving feature data including time series data for multiple sensor devices associated with the device and receiving an alert indicator for the alert. The method includes processing a portion of the feature data that is within a temporal window associated with the alert indicator to generate feature importance data for the alert. The feature importance data includes values indicating relative importance of each of the sensor devices to the alert. The method also includes identifying one or more historical alerts that are most similar, based on the feature importance data and stored feature importance data, to the alert.

FAILURE DIAGNOSTIC SYSTEM AND FAILURE DIAGNOSTIC METHOD OF MOTOR ENCODER
20230304794 · 2023-09-28 ·

A failure diagnostic system of a motor encoder is disclosed and includes a motor, an encoder, a servo driver, and a safety module. The servo driver controls the motor through a current command. The safety module continuously obtains a feedback position of the motor through the encoder. When the safety module determines based on the feedback position that the current state of the motor is consistent with a pre-determined disturbance condition, the safety module requests the servo driver to output an additional current command to disturb the motor. Next, the safety module determines whether the encoder is failure based on a variation of following feedback position.

Oil level warning at hydraulic impulse wrenches

A method and a device for detecting the oil level in a hydraulic pulse unit at an impulse type power wrench, wherein the pulse unit comprises an oil filled pulse chamber, a motor driven inertia drive member, and a kinetic energy receiving member connected to an output shaft and intermittently coupled to the inertia drive member via an oil cushion to receive kinetic energy from the inertia drive member during repeated energy transfer phases. The rotation speed of the inertia drive member is measured both at the start of a pulse generating phase and at the end of that phase, wherein the two measured speeds are compared to each other, and when the speed at the end of the pulse generating phase exceeds the speed at the end of that phase by a certain percentage a faulty signal is emitted indicating a too low oil level in the pulse unit.
