The challenge
A transport operator oversees equipment spread across a long corridor: roadside cabinets, power supplies, environmental sensors, communications equipment and selected rail-side assets. Fault reports arrive by phone or only after a scheduled inspection, making it difficult to see which sites need attention first.
Different generations of equipment use different interfaces and communications links. Operators need useful alarms and trends without replacing every functioning field device or creating a separate monitoring screen for each subsystem.
The objective is a consistent operational view that helps teams identify faults sooner, prioritise field visits and retain a record of recurring problems. Safety-critical signalling and traffic-control functions remain under their approved, dedicated systems.
Our approach
-
Asset and interface audit
Catalogue monitored assets, available signals, power, communications coverage and existing control systems. Confirm which signals are suitable for monitoring and which systems must remain isolated.
-
Pilot monitoring design
Select a representative group of sites and connect approved non-safety-critical signals through RTUs or gateways. Define thresholds, alarm ownership and escalation paths with the operator.
-
Central visibility
Bring site status, power conditions, cabinet temperature, communications health and agreed equipment alarms into a shared dashboard with trends and event history.
-
Validate and expand
Test alarms against field conditions, document failure modes and refine the design before extending it to additional sites or corridors.
System architecture
How the layers connect, from the people using the system down to the equipment in the field.
- Control-room dashboard
- Maintenance and infrastructure teams
- Alarm acknowledgement and event history
- SCADA or IoT dashboard
- Trends, alarms and asset status
- Role-based access and reporting
- Fibre, cellular or radio where available
- Store-and-forward during link outages
- Monitored link health
- Industrial RTUs and IoT gateways
- Read-only integration where appropriate
- Existing systems retained where practical
- Cabinet power and temperature
- Equipment status and fault contacts
- Environmental and approved condition sensors
What we’d deploy
- Industrial RTUs and gateways selected after site audit
- Monitoring of cabinet power, temperature and communications health
- Integration of approved equipment status and fault signals
- Central alarm handling and historical trends
- Documented escalation and maintenance workflow
- Network segmentation and access controls appropriate to the site
Target outcomes
Targets we would design and report against, not measured results from a named client. Actual results depend on the baseline established in the audit.
