Abstract
Devices, systems, and techniques are described that relate to the monitoring of various types of components in industrial systems. These include battery-less monitors that run on power harvested from their environments, systems for acquiring monitor data for the components in a facility, and/or techniques for processing monitor data to reliably determine the status of individual components and other system parameters.
Claims40
A device, comprising:
- one or more sensors configured to generate one or more signals representing at least vibration of a machine component in one or more dimensions and temperature of the machine component relative to an ambient temperature;
- control circuitry configured to generate sensor data using the one or more signals generated by the one or more sensors, wherein the control circuitry is configured to:
- generate the sensor data in a first data capture mode responsive to a first wakeup message by processing the one or more signals generated by the one or more sensors to generate first vibration data and first temperature data,
- determine, using the first vibration data and the first temperature data, that operation of the machine component represents one or more changes in an operating mode or one or more failure modes,
- generate the sensor data in a second data capture mode responsive to a second wakeup message different from the first wakeup message by processing the one or more signals generated by the one or more sensors to generate second vibration data and second temperature data, at least a portion of the second vibration data having a higher resolution than a corresponding portion of the first vibration data,
- time-align the first vibration data and the second vibration data, using timing information of the first wakeup message and the second wakeup message, to produce aligned vibration data, and
- determine a state of the machine component using at least the aligned vibration data;
- a transmitter configured to transmit the sensor data to a remote device;
- an energy storage device configured to store at least a portion of energy harvested by an energy harvesting device from a deployment environment;
- and
- power management circuitry configured to:
- control storage of energy by the energy storage device, and
- control delivery of power generated from stored energy to the control circuitry and the transmitter.

- triggering a first instance of a second data capture mode to capture higher resolution data by the sensing device responsive to a second wakeup message different from the first wakeup message;
- receiving third vibration data generated by the sensing device during the first instance of the second data capture mode, the third vibration data representing vibration of the machine component, wherein at least a portion of the third vibration data is characterized by a higher resolution than corresponding portions of the first and second vibration data;
