Introduction

Below are the latest updates made in the Augury between March and April 2024.

The updates consist of your comments and feedback and include:

Continuously Learning AI

This new capability has been made possible through our recent continuously learning AI enhancements:

With these AI enhancements, we can now triangulate between all the information we gather to keep the models improving.

Watch for more detectors coming out soon due to these enhancements!

Improved accuracy of the Structural Mechanical Looseness

We rolled out an improved & specialized “Structural Mechanical Looseness” detector that has higher accuracy and identifies more specific fault root causes that technicians can address.

Inforcing Fault Frequency Trending - Faster, Highly Precise Fault Diagnostics

Your VA and RSM team can now set up forcing frequency trending on your machines.

Machine faults like bearing wear that appear (e.g., Ball pass frequency outer/outer race failing frequency) have signature vibration frequencies: by monitoring them, we can automatically detect & diagnose a fault when these features are elevated.

A cliff or relevant trend on any of these frequencies indicates the fault is present.

How does it work?

Your reliability team will set up the forcing frequency table for your machine down to the specific component (e.g., bearings).
Using the calculated RPM/speed of the motor, the platform searches for nearby peaks to the labeled forcing frequency.
The frequency amplitude is now outputted as a feature, enabling it to be trended.
The Vibration Analyst will then set up thresholds to trigger alerts and automatically diagnose specific faults.

Faults Diagnosed/Monitored

Bearing Wear:

Ball pass frequency outer (BPFO) - outer race failing frequency
Ball pass frequency inner (BPFI) - inner race failing frequency
Fundamental Train Frequency (FTF) - cage failing frequency
Ball Spin Frequency (BSF)- rolling element failing frequency

Component Faults:

Motor/Driven Shaft
Belt Pass
Gear Mesh
Vane Pass
Screw Mesh
Rotor Mesh
Blade Pass
Female/Male Rotor
Rotor Bar Pass
Piston Frequency

Information enrichment - Network info

Users will be able to view additional valuable information in the IoT Device’s side panel to identify desired devices better and troubleshoot connectivity issues:

Network information section with details of network owner, network name, and connection type
Improved indication of device type
MAC address for Nodes and Routers

Improved indication for offline Access points alert.

EndPoint firmware improvements:

We have improved the EP diagnostics, Connectivity, & Battery consumption.
We report temperature data with decimal points (increased precision in temp readings).
The New Hanning window feature helps mitigate spectral leakage (useful for Vibration Analysts).
The node-to-EP pull connection is now the default communication configuration (which improves data efficiency and battery life).
Feature extraction functionality enabled on EP 1 / 2 and older EPs (for future edge diagnostics capabilities)
Advanced Sampling increases battery life.
Pulse-width modulation to dim LEDs extends battery life.
