Tunnel Exterior Brightness Detector

1. What is a tunnel brightness detector?

Tunnel exterior brightness detector is a device used to monitor the brightness outside the tunnel. It uses photosensitive devices and computer technology to measure the light intensity at the tunnel exit to determine whether supplementary lighting is needed.

2. What is the function of the brightness detector outside the tunnel?

The brightness detector outside the tunnel can monitor the light intensity at the tunnel exit in real time. When the light is insufficient, the supplementary light system is automatically triggered to provide supplementary light to ensure the driving safety of vehicles when switching between inside and outside the tunnel.

3. What are the characteristics of brightness detectors outside tunnels?

The brightness detector outside the tunnel has the characteristics of high sensitivity, accurate measurement, and good real-time performance. At the same time, it can also transmit detection data to the monitoring center in real time through data transmission technology, providing data support for tunnel operation and management.

4. What are the application fields of brightness detectors outside tunnels?

Tunnel exterior brightness detectors are mainly used in highways, urban tunnels, mines, subways and other places to ensure the driving safety of vehicles when switching between inside and outside tunnels.

5. What are the advantages of brightness detectors outside tunnels?

Compared with traditional timing and quantitative lighting methods, tunnel brightness detectors can more flexibly control tunnel lighting, save energy, improve road section traffic capacity, and improve road section safety and service levels.

6. What are the installation and maintenance costs of brightness detectors outside tunnels?

The installation and maintenance costs of the brightness detector outside the tunnel are low, and remote monitoring and maintenance can be achieved. At the same time, it also has a long service life and low maintenance rate, bringing more convenience to tunnel operation and management.
