Improving road safety is a goal for all those associated with Traffic Control systems. Nowhere is it more important than in Europe’s road tunnels where fatal disasters have occurred several times in previous decades.

Tunnel Monitoring systems typically utilise an Industrial Ethernet backbone to distribute data from sensors captured by PLCs or remote I/O modules that are strategically deployed around the tunnel. Because real-time monitoring of conditions at all parts of the tunnel is critical in such systems, redundant or dual redundant network architectures are often employed. Amplicon’s Industrial Ethernet products have environmental specifications suitable for installations in such environments and provide extensive redundancy protocols so complex and highly reliable networks can easily be designed. Amplicon’s technical team can help with all elements of network design for Tunnel Monitoring systems.

Many Tunnel Monitoring systems will adopt a SCADA-like architecture with I/O processed and displayed at central points. Amplicon’s range of Rackmount and Panel PCs are commonly used as a highly reliable Windows or Linux platform to host such software. Our Embedded PCs are used where computers need to be fitted into smaller roadside enclosures and environmental conditions are more harsh than the more usual air-conditioned control rooms.
