INNOVATION EDGE™: BRIDGE STRIKE MONITORING TECHNOLOGY
Murphy, in collaboration with Network Rail, has developed a cost-effective system for remote monitoring of damage to rail structures.
Description
The bridge strike monitoring technology was developed by Murphy in collaboration with client Network Rail. The technology can be used on rail-over-road bridges which are lower than the standard height. Its application is particularly crucial where the leading edge of the structure is vulnerable to being struck by high vehicles.
The technology comprises several remote cameras that are installed on the underside of the bridge structure. The number of cameras is dependent on the bridge layout.
Tell-tale targets are put in each camera’s line of vision, typically on the opposite edge of the bridge, to confirm the extent of bridge movement resulting from a strike.
The technology is powered by a solar panel which is connected to a battery and control box. Stored inside the control box are a router, a network switch and an inverter. In the event of a vehicle striking the structure, a notification text message is sent to Network Rail operations controller. The structure can then be viewed remotely via the hosting website.
Benefits
- Allows remote monitoring of structures in isolated geographical locations.
- Aids immediate assessment of impact and damage severity, allowing Network Rail to take action and avoid unnecessary track closures and restrictions.
- Has a low carbon footprint and sustainability credentials thanks to solar power.
- Reliable and easy to maintain in addition to offering potential for future savings for Network Rail.
