We develop power line lighting control systems for road tunnels, underpasses and areas

Powerline-addressable control and monitoring for tunnels, underpasses and other infrastructures that provide substantial energy savings, reduced operating costs and improved user safety.

The control and monitoring solutions developed by Nyx Hemera Technologies use the latest advanced power line communication technologies available on the market.

TLACS uses methods that combine techniques based on different frequencies and transmission speeds to achieve ultra-robust communication over power lines.

  • The modulation technique is a mixture of orthogonal frequency division multiplexing (OFDM) and multi-frequency shift keying (MFSK) for efficient transmission;
  • The use of up to 8 frequency channels optimizes the success rate of the communication;
  • The system uses an adaptive communication speed of 360bps to 23000bps that automatically adjusts to the traffic on the power line.

Power line communication does not require the installation of additional wiring for control and supervision. Using existing electrical wiring means significant savings on installation time, wire and connector purchases and lighting system maintenance.
