IoT Basic Elements — matching IoT pipeline stages to factory devices
IoT systems follow a four-stage pipeline: collect → transmit → analyze → utilize.
For factory equipment maintenance:
| Stage | Role | Matched device/service |
|---|---|---|
| Data collection (A) | Gather raw readings from equipment | c) Temperature sensor for equipment |
| Data transmission (B) | Move data across the network | d) Wireless communication within factory |
| Data analysis (C) | Process data to find anomalies | a) Abnormal value judgment tool |
| Data utilization (D) | Act on insights | b) Display for work instructions |
The correct answer is c).
Why not others:
- a) "Abnormal value judgment" is an analysis function (detecting outliers), not raw data collection
- b) Displaying work instructions is the end use of processed data, not its collection
- d) Wireless communication is a transmission medium, not a sensing device
Key rule: In IoT pipelines, data collection = physical sensors (temperature, vibration, pressure). Transmission = network tech. Analysis = software processing. Utilization = actionable output (dashboards, alerts, instructions).
