Internet of things device for monitoring the motion of oscillating equipment

An internet of things (IoT) device for monitoring movement of an oscillating mechanical device, comprising:

• an accelerometer attached to the oscillating mechanical device;
• a movement measurer to obtain movement data from the accelerometer attached to the oscillating mechanical device;
• a transform calculator to generate a power spectrum from the movement data;
• an analyzer to generate an alert if the power spectrum is outside of a mask;
• a radio transceiver to transmit the alert;
• and
• a comparator to compare a power spectrum for upstrokes to a power spectrum for downstrokes to determine if pumping efficiency has changed.

An apparatus for monitoring a plurality of oscillating mechanical devices, comprising:

• a plurality of Internet of Things (IoT) devices, each IoT device corresponding to a respective one of the plurality of oscillating mechanical devices, the IoT devices each comprising:
• an accelerometer attached to the respective oscillating mechanical device;
• a movement measurer to obtain movement data from the accelerometer attached to the respective oscillating mechanical device;
• a transform calculator to generate a power spectrum from the movement data;
• and
• a backend processing system to accept data from each of the IoT devices, wherein a power spectrum for each of the plurality of oscillating mechanical devices is combined into a single plot, and the backend processing system comprises an analyzer to apply an alert mask to the single plot to determine if any of the plurality of oscillating mechanical devices is having operational problems, the backend processing system to perform frequency analysis to determine a pumping rate, upstroke loadings, downstroke loadings, pumping rate variations across the mechanical oscillating devices, and to identify idle mechanical oscillating devices.
