Infrastructure for Predictive Maintenance for Production Equipment

Predictive maintenance AI needs explicit documentation of equipment specifications, normal operating parameters, and maintenance history to distinguish normal variation from anomalies. The system must know "this equipment normally vibrates at X Hz under Y load"—if that knowledge exists only in veteran technicians' heads, AI generates false positives that erode trust.

Predictive models require continuous sensor data and complete maintenance history. Manual entry or periodic sampling misses the subtle drift patterns that precede failures. The system needs automated feeds from vibration sensors, temperature sensors, power meters, and CMMS work orders. Any gap in data history creates blind spots in failure prediction.

Predictive maintenance requires correlating sensor data with maintenance history across equipment types. The system must match "equipment A, sensor B, timestamp C" with "work order D, failure mode E, repair action F." Consistent schema enables cross-equipment learning—bearing failures show similar patterns. Without structure, each machine is an isolated island.

Real-time predictive maintenance requires continuous access to sensor data streams (often via OPC UA or MQTT) and CMMS maintenance history. Without API access, systems rely on batch exports that create lag between anomaly detection and alert. Edge AI deployments (2025-2026 trend) require sub-second access to sensor data for real-time response.

Predictive models depend on current data about equipment condition and maintenance state. If yesterday's bearing replacement isn't reflected, AI continues alerting about the old bearing. If baseline parameters drift as equipment ages but aren't updated, AI flags normal aging as anomalies. Maintenance history must update immediately; baselines need hourly-daily refresh.

Predictive maintenance effectiveness depends on correlating sensor data with maintenance history AND production context. "High vibration" means different things at high load vs. idle. System must integrate sensor data, CMMS, MES (production context), and environmental monitoring. Without integration, alerts lack context that determines true urgency.
