POWER EFFICIENT MACHINE DIAGNOSTIC MONITORING USING MULTIPLE VIBRATION SENSOR WIRELESS CONFIGURATION

A wireless monitoring unit performs condition monitoring associated with a test point location of a host machine. The unit includes a high performance vibration sensor useful for monitoring the host machine for fault conditions and the like. The unit includes a second vibration sensor that has poorer metrological performance, but draws a comparatively insignificant amount of power from the battery. The second sensor takes a vibration measure periodically, which measure is processed to evaluate whether the machine is in a state eligible to undergo a health assessment. Diagnostic monitoring using the high performance vibration sensor is enabled only when the host machine it is in the eligible state. A low power temperature sensor provides additional data for guarding against a false trigger, in effect allowing the processor to distinguish against vibration from another machine propagating to the host machine causing the host machine to vibrate while the host machine is not running.

FRONT-LOADING WASHING MACHINE AND UNBALANCE DETECTION METHOD AND DEVICE THEREOF
20180148880 · 2018-05-31 ·

The present disclosure relates to a front-loading washing machine and an unbalance detection method and device thereof. The method comprises: when a drum operates at a low constant speed, detecting the torque of the drum and acquiring average torque values; when the roller operates at a constant acceleration speed, acquiring average torque values and a minimum value of the average torque values of the drum in real time; determining whether a difference between the average torque and the minimum value of the average torque values is greater than a preset unbalance threshold; and if so, determining that dynamic unbalance occurs on the drum; otherwise determining that no dynamic unbalance occurs on the drum. Because no sensor is needed for unbalance detection, cost and the detection difficulty are lowered, and damages to mechanical components due to collisions caused by dynamic unbalance when the drum operates at a high speed is avoided.

DYNAMIC BALANCER

A dynamic balancer includes a support frame with a frame plate that has a spindle opening through which a spindle assembly with a rotatable spindle shaft is received. A sensor plate is coupled to at least the support frame, and at least one force sensor is coupled between the sensor plate and the spindle assembly to detect force variations therebetween as the rotatable spindle shaft rotates. A related method for detecting a balance condition of a tire includes providing a plurality of force sensors maintained in a substantially horizontal plane with respect to the tire's rotation, chucking and inflating the tire, spinning the tire to a predetermined speed, generating force data from the plurality of force sensors, calculating an imbalance condition from the force data, and marking the tire at a location of imbalance if the imbalance condition exceeds a predetermined threshold.
