Tunnel and highway monitoring with DTS equipment

A starting configuration for linear temperature monitoring, fire-risk detection, and alarm zoning in long infrastructure corridors.

Hardware foundation

DTS equipment monitors temperature continuously along optical fiber installed through tunnels, service galleries, utility corridors, or roadside cable routes.

Software workflow

Operators can review temperature profiles, configure alarm zones, inspect historical trends, and export alarm data for local safety systems.

Project fit

Useful for long linear assets where point sensors are difficult to install densely and where location-aware alarms reduce inspection time.

Typical monitoring goals

  • Continuous temperature awareness along tunnel, gallery, bridge, or highway cable routes.
  • Early fire-risk detection using regional temperature rise, absolute threshold, or hot-spot logic.
  • Zone-based alarms that can map events to sections, ventilation areas, cabinets, or maintenance access points.

Useful system outputs

  • Temperature profile and waterfall visualization
  • Alarm zones and event records
  • Data export for SCADA, traffic management, or local safety platforms
  • Configuration support for fiber route, channel length, and alarm thresholds

How Planck Sensing supports this application

Planck Sensing can help select the DTS range and channel configuration, align fiber-route assumptions with the monitoring area, and prepare software outputs for alarm handling, visualization, and system integration.
