Tunnels are built using the latest and safest technologies
AC500 PLCs, CP600 HMIs, motors, drives and the Automation Builder integrated engineering suite are a perfect fit for tunnel applications, resulting in engineering productivity.
Tunnels are created wherever local conditions do not permit an efficient road or rail routes. They connect people by shortening travel times significantly, protect man and nature from noise and exhaust fumes and make remote areas accessible.
The safety standards for tunnels are regularly reviewed and adapted to the latest findings. New tunnels will be built and equipped on the basis of the most up-to-date and safe technologies and constructions, while older tunnels will have to be upgraded.
Tunnel automation with an end-to-end portfolio
ABB offers a portfolio of higher-level control systems (SCADA) which act on top of the local ABB PLC-based architecture. All technical subsystems and field devices of the tunnel system can be controlled and monitored from one or several central locations. An end-to-end portfolio with a high number of scalable products and options, from the field layer right through to the management and visualization layers saves significant engineering time and money, while at the same time ensuring a highly available, safe and future-proof tunnel system.
Protection and Security
Tunnel ventilation ensures the safety of people and equipment in every situation. The system includes smoke extraction, fresh air circulation, and advanced video and radar control for early hazard detection. Emergency evacuation systems provide safe waiting areas throughout the tunnel. Modern lighting technology supports safe navigation and clear visibility of vehicles and passengers, while manual call points and integrated firefighting systems enhance overall safety.Control and Safety
The AC500 platform delivers high availability and integrates safety PLCs and drives for optimal tunnel fan control. Comprehensive solutions include control systems, switchgear, power monitoring, and low- and medium-voltage distribution. Emergency power supply ensures reliable operation even in critical conditions.Communication and Reporting
Remote monitoring and IoT capabilities enable real-time insights and maintenance access. The public announcement and communication systems are reachable from every point in the tunnel. Optimized traffic flow is achieved through data acquisition via AC500, supported by signal systems and dynamic traffic signs.Supervision and Monitoring
Local and higher-level control systems (SCADA) provide complete oversight through intuitive dashboards and HMI CP600 interfaces. Energy management covers the entire system, while drive systems ensure efficient tunnel ventilation and operation.System architecture
