DESCRIPTION
Digital renovation is being carried out to overhaul the centralised control of the M-30 motorway tunnels. The update will improve road safety and sustainability with greater automation of the system and more efficient AI-based management of the motorway's tunnels.
The project focuses on improving the efficiency of ventilation systems, lighting and other equipment.
By law, and for reasons of safety, in-tunnel lighting control devices (DALI) and modules that monitor energy consumption are being replaced to optimise consumption based on the required lighting conditions.
The overhaul encompasses the measures necessary to automate ventilation control criteria in the event of a fire. Due to the tunnel's numerous different sections, this is a complex undertaking which also entails carrying out a number of smoke tests for verification purposes.
Measures include renewing, installing, programming or configuring and commissioning equipment as well as performing tests on all three levels of the M-30 tunnel control system:
- Level 1: Distributed Control Units (DCU): Replacement of communications cards, in-tunnel lighting control devices (DALI), energy modules and power supplies for all of Level 1.
- Level 2: Universal Remote Stations (URS): These stations form a communication loop that currently includes 144 non-industrial units that are particularly sensitive to the underground environment. After the renovation, the intelligent link between the field systems and the control centre will comprise 72 redundant PLC (Programmable Logic Controller) field units in 36 different locations and a PLC coordinator.
- Level 3: Control Centre: The centre has servers that receive all of the signals and alarms from equipment installed in the tunnel as well as tunnel entry data sent from the DCUs and URSs via a fibre optic ring. After the updates, 111,000 signals from the 21 systems in the M-30 tunnels will be integrated: information panels, traffic lights, in-tunnel temperature, gas emissions, lighting, ventilation, emergency exits, fire system, barriers, etc.
