Control of chairlifts, snow cannons and floodlights in Switzerland and Austria

The further subsequent expansion of ski centers with snow cannons and floodlights results in demands for secure central control and monitoring.

Task:

Required was a german technical inspction association (TÜV) -compliant control of the lift, on the carrying cable and a remaining wire of a telephone line.

In another system, the snow cannons and the floodlights had to be controlled via the existing mains supply line.

Realization:

The UNITRO modules are used: LM I/O- and C3-modules with Powerline couplers.

Communication takes place via the very secure Powerline PLT22 protocol in C-band, with capacitive network couplers when using the power lines.
