Can legacy air compressors without data interfaces be monitored?

Yes. Externally mounted vibration-temperature sensors on bearing housings capture the data, and current transformers capture motor current — no compressor data output required. DTU aggregates data and uploads via 4G/Ethernet.

How far in advance can faults be predicted?

Gradual faults such as bearing degradation and screw wear typically show observable trends 7-14 days ahead. Sudden fractures cannot be predicted — the system must be used alongside routine inspections.

Which compressor brands are supported?

The monitoring approach is brand-agnostic. Whether Atlas Copco, Ingersoll Rand, Sullair or domestic brands — all data is collected via external sensors, 100% compatible.

Does installation require a shutdown?

Sensor installation can be completed while the compressor is running. Surface-mount sensors only need surface cleaning and adhesive attachment — no shutdown required.

Online vibration, temperature & current monitoring for air compressors — early warning of bearing degradation and overtemperature shutdown, reducing unplanned downtime

Solution Overview

Online health monitoring for air compressors: collects vibration, temperature & current. AI learns operational baseline to identify bearing degradation and cooling anomalies early, reducing unplanned downtime. No equipment replacement, no line modification — data connected in 30 minutes.

Problems Solved

Air compressor failure halts the entire production line

The air compressor is the lifeline of plant utilities. A single unplanned stop not only cuts compressed air supply but brings all pneumatic equipment to a halt — losses of thousands of dollars per hour.

Recurring overtemperature shutdowns with unknown root cause

Cooler blockage, lubricant degradation, ambient temperature swings — overtemperature shutdowns look like temperature issues on the surface but have diverse root causes that are hard to pinpoint with manual experience alone.

Scheduled maintenance cannot prevent sudden failures

Consumables replaced by running hours, but bearing wear and screw degradation timelines vary enormously with operating conditions. Fixed-interval maintenance still misses failures.

Traditional Solution vs ZHIYUAN

Alert MethodFixed threshold alerts: only fire at limit crossings, blind to slow degradation. A single fault floods dozens of useless alerts, burying real risks.AI time-series anomaly detection: learns each device's baseline, catches slow drift and hidden anomalies. 80% fewer false alarms, alerts routed to the right people.

Notification & ClosurePhone calls/group chat: alerts dumped in chat, who handles what? Night alerts buried, discovered next day.WeCom/SMS graded push + work order automation: graded, person-specific routing. Unacknowledged alerts auto-escalate. Full traceability: alert → work order → resolution → archive.

Integration & RetrofittingCostly retrofit & downtime: new monitoring needs rewiring, equipment swap, production stoppage — long cycle, lost output.Reuse existing sensors, plug & go live: compatible with 95% DTUs/sensors. MQTT/Modbus standard protocols. No production line changes — 30-minute data integration.

Data ValueReal-time only, no history: manual logs capture instant values only — no trend visibility, can't replay fault evolution.Time-series database + history replay: massive long-term storage, any-range curve playback with work order records to reconstruct full fault picture and continuously improve O&M strategy.

Key Features

Vibration Trend Monitoring
Monitors bearing housing and casing vibration severity. AI learns normal operating baseline to identify early signs of imbalance, misalignment and bearing wear.
Multi-Point Temperature Monitoring
Simultaneously collects discharge temperature, oil temperature and cooling water temperature to assess cooling system efficiency degradation and oil deterioration trends.
Operating Condition Analysis
Records load/unload frequency, running hours and start-stop counts to identify frequent cycling and extended idle conditions.
Screw/Bearing Degradation Warning
Combines vibration spectrum with temperature trends to provide 7-14 day advance warning of screw wear and bearing degradation, with maintenance window recommendations.
Alert-to-Work-Order Closure
Abnormal alerts auto-generate maintenance work orders — dispatch → accept → process → archive with full traceability, building per-machine health records.
