An industrial process is a stable, monitored production or operational procedure involving machinery, materials, and process conditions. Manufacturing assembly lines use monitoring to protect output quality, equipment reliability, and workplace safety. section 1.1.5
Industrial-process monitoring treats deviations from normal behavior as operationally important:
- Unexpected friction, voltage, temperature, or other measurements can indicate equipment wear or developing faults. section 1.1.5
- Severe anomalies may trigger alerts or slow or stop the process; less severe findings can support scheduled maintenance. section 1.1.5
- An anomaly indicates deviation from the norm, not necessarily an imminent failure, especially when failure examples are scarce. section 1.1.5
Figure 1.1 Temperature readings from sensor data presented as a time series. The x-axis tracks time in seconds and the y-axis tracks the temperature. There is an unusually high level of fluctuation at 200 seconds and an usually low level at 800 seconds.
Use the sensor time series to inspect unusually high fluctuation near 200 seconds and unusually low readings near 800 seconds. section 1.1.5
