Montmartre Incline Lift: Secure Radio Communication for Reliable Operation in Demanding Environments

The inclined lift connects different levels of Montmartre and is used by large numbers of visitors every day.

The lift is controlled automatically and requires reliable data transmission between the stationary control unit and the moving cabin throughout the entire journey.

Implementing the communication system presented several technical challenges:

• No continuous, reliable cable connection was possible due to the movement

• High mechanical stress on moving parts

• Restricted or changing visibility conditions along the route

• An environment prone to interference (metal structures, buildings, radio sources)

However, uninterrupted and stable signal transmission was essential for safe lift operation.

A DATAEAGLE wireless solution is used to transmit control data wirelessly:

• Wireless PROFIBUS communication between the controller and the cabin

• Robust wireless technology with high immunity to interference

• Continuous connection even whilst in motion

• Integration into the existing automation infrastructure

The system solution operates transparently, just like a wired connection, without requiring any modifications to the controller.

The use of DATAEAGLE has enabled stable and secure data transmission:

• Reliable operation of the inclined lift over the entire route

• Reduced wear and maintenance due to the elimination of cable connections

• High availability even under demanding conditions

• Increased operational safety for both people and the system

The wireless solution thus represents a sustainable and cost-effective alternative to wired signal transmission.
