A command and control system at the £260m New Tyne Crossing Project has been supplied by Sicura Systems.
Video surveillance at the River Tyne tunnel complex is managed by software developed by Sicura. This includes DigiSCADA which offers monitoring and control of all connected devices and systems, and DigiLive work-stations which provide the interface between SCADA and DigiWall, a fully-redundant video wall operating between mirrored servers. When fully operational at the site, DigiWall will display footage from fixed and PTZ cameras besides data from client devices including access control, fire/smoke detection and ventilation.
DigiWall users are able to view a range of data sources including video footage, site schematics, public information displays and building management status.
IP streams from analogue cameras, which are located mainly within the tunnels under the Tyne and at toll plazas, are being generated using blade encoders. Transmission of the 25 frames per second footage is via a fully fault-tolerant fibre network designed and installed by Vital Technology. Vincenzo Roberti , Managing Director at Sicura Systems, said: “If problems occur in a road tunnel they tend not to be isolated incidents but rather a sequence of events. It was a requirement at tender stage that CCTV for this project should be integrated with SCADA . The sheer range of data on which the Sicura software can report is important for our clients.”
He added: “The tunnel operator [TT2] will be using Sicura’s DigiWall display solution and DigiLive management software to process disparate information types, even benefiting from video analytics functionality via Vehicle Automatic Detection System (VAID). Scenarios include sterile zones such as central reservations and escape lanes as well as speed and direction of movement. As with other plant or client devices, an alert is flagged as a video pop-up on DigiWall. Uniquely with our system, an operative can immediately view and control any incident regardless of it being SCADA-related or a VAID incident from the nearest camera as well as bringing in multiple adjacent camera views.”
Background
To date the New Tyne Crossing Project has included construction of a second vehicle tunnel featuring four 90-metre immersed tube sections under the River Tyne, redesign of the southern interchange at the entrance to the original tunnel and development of a toll plaza on the new northern approach to the vehicle tunnel. The original vehicle tunnel (which dates from 1967) is closed for refurbishment. The Tyne Tunnels site (which includes dedicated tunnels for pedestrians and cyclists) is located 11 km to the east of Newcastle upon Tyne and forms part of the A19 road.
