Conveyor Belt Monitoring & Fire Detection

Roller acoustic early warning + temperature cross-check — detect roller faults before they ignite.

Challenges

Three pain points of conveyor safety

Thousands of rollers, random failures

A conveyor has thousands of rollers; wear and seizure occur randomly, and manual acoustic inspection can't guarantee coverage or timeliness.

Seized rollers cause fires

A seized roller keeps rubbing the belt and heating up — the leading cause of conveyor fires, often already smoking when discovered.

Harsh environment

Dust, noise and moisture make traditional electronic sensors failure-prone and hard to maintain — monitoring has long been absent.

Solution Architecture

Architecture: acoustic listening + temperature cross-check

DAS hears early, DTS confirms accurately — a dual-signal pre-fire loop.

Acoustic · DAS

Roller acoustic early warning

DAS continuously listens to roller sounds along the conveyor; the AI acoustic model separates wear and seizure signatures from background noise, warning and localizing roller anomalies before failure — shifting maintenance from firefighting to proactive replacement.

Temperature · DTS

Heating double-check

DTS monitors the temperature profile along the line as a second verification of roller seizure and bearing overheating — raising alarm confidence and preventing fire.

FAQ

Frequently Asked Questions

Roller wear and seizure produce acoustic signatures distinct from normal running. DAS listens continuously along the conveyor, and the AI model identifies anomalies with meter-level localization — maintenance replaces the exact roller without a full-line inspection.
LandSub Global's AI recognition is trained for high-noise industrial environments: 0.03 rad/√Hz sensitivity plus the acoustic model stably distinguish roller anomalies from conveyor running noise.
Acoustics catch problems early, temperature confirms them accurately: a seized roller's heating phase is directly captured by DTS, and the two signals cross-verify to cut false alarms and misses — a complete pre-fire loop.
DAS covers 160 km (dual channel) with industry-leading listening points, so one interrogator covers most single conveyor corridors; the exact configuration depends on corridor length and fiber resources.
