Entrance Section · Transition Section

Outside Tunnel Brightness Detection: Brightness sensors collect outside tunnel brightness in real time and automatically calculate the required enhanced lighting for the entrance section.
Graded Dimming: Lamps in the entrance and transition sections are turned on in grades according to brightness requirements, with automatic switching for sunny days, cloudy days and nights.
Smooth Transition: Lights shift gradually to eliminate the "black hole effect" and "white hole effect" and ensure visual safety for driving.
Timing and Scenarios: Lighting strategies are adjusted automatically by season and time period.
Central Control: The monitoring center conducts unified monitoring of entrance lighting circuits.

Solution Architecture

The system adopts a layered distributed architecture, consisting of three major modules: platform management layer, network transmission layer and field device layer. It is compatible with mainstream industrial protocols such as KNX, BACnet, DALI and Modbus, and fully connects various subsystems including tunnel lighting, ventilation, fire protection, power supply and distribution. It eliminates device silos to realize unified monitoring, intelligent linkage and data intercommunication of full-scenario devices.

Platform Management Layer

(Centralized Monitoring · Scene Deployment · Energy Consumption Decision-making)

Unified management by tunnel monitoring center and operation departments; simultaneous display of intelligent lighting platform, environmental monitoring platform and energy consumption monitoring platform on one screen. One-click deployment of daily, peak, night and emergency scenarios with real-time visibility of tunnel status.

Network Transmission Layer

(TCP/IP · KNX · BACnet · Modbus)

Reliable transmission via tunnel LAN and ring network switches. Supports multi-protocol access including RS485, DALI, BACnet and Modbus. It collects device status and data on the uplink and issues control commands on the downlink for bidirectional connectivity.

Field Device Layer

(Controllers · Panels · Sensors · Actuators)

Intelligent panels, dimming modules and DDC controllers perform control functions. Brightness, CO, visibility and wind speed sensors perceive the environment. Smart electric meters measure energy consumption. Emergency lighting and fire protection modules work in linkage for on-demand scheduling.

Core Value

Safety & Reliability

Smooth transition at tunnel entrances, forced emergency linkage cut-off and real-time fault early warning ensure the safety of tunnel traffic and personnel evacuation.
Energy Saving & Consumption Reduction

On-demand lighting, traffic flow linkage and time-divided control jointly cut energy consumption, reducing long-term tunnel operation energy use.
Efficient Operation & Maintenance

Single-screen management at the monitoring center, remote equipment monitoring and proactive fault early warning reduce manual inspection and response time.
Lighting Environment Quality

Stepless dimming enables smooth light transition to eliminate black hole and white hole effects, improving drivers' visual comfort and safety.
