9 interactive 3D scenes: sensing installation, event location and field response.

Cable-gallery hot-spot detection & fire warning

01 / DTS

Power plants · substations · data centers

Cable-gallery hot-spot detection & fire warning

For multilayer cable galleries and trays in power plants, substations, data centers and factories. Continuously track cable and joint temperatures, detect localized overheating and locate the affected section. Explore a four-level gallery, temperature profiles, control-room alarms and the response sequence with an integrated fire-control system.

High-precision configurations locate hot spots to ±0.05 m, with measurements in 3 seconds or less per kilometer to pinpoint cable overheating.

Industrial busbar & warehouse hot-spot monitoring

02 / DTS

Battery · photovoltaic · semiconductor · logistics

Industrial busbar & warehouse hot-spot monitoring

For lithium-battery, solar-cell and semiconductor factories, as well as logistics warehouses. Detect and precisely locate small hot spots at overhead busbars, rectifier-bus joints and storage racks. Two busbar channels and two rack channels demonstrate temperature-rise detection, device alarms, software location and field response.

Locate small hot spots to ±0.05 m, with measurements in 3 seconds or less per kilometer to detect overheating at busbar joints and storage areas.

Conveyor bearing overheating & fire warning

03 / DTS

Mining · ports · steel · cement

Conveyor bearing overheating & fire warning

For continuous conveyors in mines, ports, steelworks and cement plants. Sensing cable tracks temperature near idler bearings, drives and the belt to locate hot spots caused by friction or seizure. Follow hot-spot development, temperature profiles and control-room alarms to see how monitoring directs inspection and coordinated response.

High-precision configurations locate hot spots to ±0.05 m, helping teams find overheating rollers and bearings with less manual inspection.

Highway tunnels · urban tunnels · underpasses

Traffic-tunnel fire location & response

For highway tunnels, urban road tunnels and underpasses. Continuous temperature profiles reveal abnormal heating from vehicle or other tunnel fires and locate the alarm section. Follow the sequence from heat rise and device alarms to control-room location and integrated fire response, including the subsequent cooling trend.

Long-range configurations monitor up to 40 km per channel, tracking tunnel temperatures and fire locations with support for integrated fire response.

Pipeline intrusion & leak-related acoustic monitoring

05 / DAS

Oil & gas pipelines · chemical corridors · water mains

Pipeline intrusion & leak-related acoustic monitoring

For oil and gas pipelines, chemical-pipeline corridors and water mains. Fiber sensing detects excavation, manual work, human activity and leak-related acoustic signatures, locating suspect sections for classification and inspection. Tour a 51.3 km route and follow each event through optical transmission, device alarms and control-center response.

Monitor up to 100 km per channel, with alarms configurable to as fast as 1 second to flag construction activity and potential leaks.

$Horizontal-well fracturing & production diagnostics$ 06 / DAS

Oil & gas · shale resources · geothermal wells

Horizontal-well fracturing & production diagnostics

For oil, gas, shale and geothermal wells. Distributed downhole acoustics supports analysis of fracturing response, production activity, suspected leaks and seismic-wave propagation. Explore an 8,135 m horizontal well using depth–time waterfalls, waveforms and spectra, interpreted alongside pressure, flow and operational records.

Sampling intervals as fine as 0.4 m reveal acoustic changes along the well, helping identify anomalies during fracturing and production.

Bridges · mines · tunnels · pipelines · slopes

Long-range strain monitoring for critical assets

Monitor load-induced fiber strain on bridges, mine roofs, tunnels, pipelines, slopes, overhead lines and subsea cables. Locate abnormal sections and assess trends. The seven-scene platform starts with a bridge, emphasizes pipeline deformation and slope movement, and illustrates roof and tunnel instability, tower loading and anchor drag.

Strain accuracy of ±20 με and long-range BOTDA coverage up to 120 km help track structural loading and deformation trends.

Perimeter intrusion warning & security response

08 / ZFDS

Energy reserves · petrochemical sites · substations · factories

Perimeter intrusion warning & security response

For energy reserves, petrochemical sites, substations and factories. Passive sensing cable on fences, wall tops or buried routes detects climbing, cutting, impacts and digging, reporting the affected zone. Follow control-room alerts, video verification, drone approach and loudspeaker warning, then the security response.

One unit manages 16 zones and raises an alarm within 3 seconds once trigger conditions are met, identifying the affected zone.
