Network Rail: CTRL Tunnel Ventilation Control
The primary function of the tunnel VCS is to supply air or extract air from the tunnels in the event of an incident as well as perform tunnel ventilation during normal train operations. The system was deemed to be safety critical, thus system development had to follow strict software assurance guidelines and was subject to regular audits to ensure that the system met the required operational safety criteria.
The following systems and services have been designed and installed:
- Mitsubishi PLC Control System
- Citect SCADA System.
- Remote Monitoring.
- SIL 2 & 3 Development.
- High Availability Systems.
- Project Design
- Installation, Testing, Commissioning.
- Audit and Obsolescence Study .
- Integrated Central Database.
- Training
SCADA System
The SCADA system was designed and developed in accordance with SIL 2 and provides the supervisory layer of the architecture and is designed to ensure optimal availability by operating on a dual-redundant basis. The SCADA servers handle all the core SCADA tasks such as communications (master PLCs, RCCS and EMMIS), alarm and event logging, data logging, trending and Archiving and provide this data to the client workstations over the network.
