Abstract

An edge device monitors a mechanical system for changes in vibration state. When an overall vibration state of the mechanical system deviates by at least a threshold from an expected vibration state, the edge device can send the data to a server for diagnostic processing. The edge device can thus monitor for a pre-failure condition that suggests an upcoming failure or a need for service. With selective sending of sensor data, the bandwidth and processing associated with diagnostics can be reserved for situations more likely indicative of a condition needing diagnosing, rather than performing constant diagnostic processing.

Claims12

Dependent claims

A system for monitoring a mechanical device, comprising:

a sensor to generate sensor data based on measurement of an environmental condition of a mechanical device, including a tachometer to measure a rotation rate of the mechanical device;
and
an edge processing device on a same side of a network connection as the sensor to compute a vibration state of the mechanical device based on the sensor data, and to determine when the vibration state differs from a reference by more than a threshold;
and to send the sensor data to a server on a remote side of the network connection for diagnostic processing when the vibration state differs from the reference by more than the threshold and when the vibration state differs from a historical energy level based on previous monitoring of the mechanical device, and otherwise to not send the sensor data to the server.
