Caption 1 - Overview of Saint-Ouen (Paris Region) train station
During the extension of Paris suburb line RER-C, it was urgent to monitor railway sleepers due to construction works at several train stations in the North-West of Paris.
The main target was to monitor soil stability and to notify in real-time the field workers if deformation was observed on rails. The monitoring system was deployed between 2010 and 2014, a long battery life was required by the rail operator.
Wireless inclinometers were used with external primary cell for a longer battery life (Ref: Beandevice® HI-INC Xtend ).
OPERATION MODE :
• DAQ Mode: Survey mode with a notification cycle of 30 minutes
• Inclinometers accuracy: ±0.05°up to ±0.02° on the Full Scale
