LG CNS PSD

Our Expertise

As the number of travelers who use public transportation increases, a system which could enhance safety and convenience for travelers is required.
PSD is the safe facility with fixed doors and sliding doors installed at the metro/train station platform which is interlocked with the doors of rolling stock for the opening and closing by the signal system recognizing the location of the rolling stock in the station.

  • Protect the passengers from having negligent accidents at the station.
  • Provide comfortable condition for the passengers blocking the wind, dust and noise from the trackside.
  • Maximize the energy-conservation with the increase in the efficiency of air conditioning system.
