System for monitoring public lighting remotely and developing energy efficiency plans

Main technical specifications
  • Public lighting control over the 4-cloud web portal
  • Energy efficiency optimisation thanks to the built-in astronomical clock
  • Integrated management of two lighting lines
  • Energy monitoring directly from the mains meter
  • Independent from the type of the bulbs used
  • Equipped with auxiliary digital input for sending alarm notifications via email
  • Alarms notifications via email in case of data transmission failure, aux contact closure (for example eventual open door of the electrical box), power threshold exceeding (customisable parameter)
  • Data acquisition settings can be customised via software (free configuration tool for PC)
  • Intenet connection via SIM card (can be supplied by Astrel Group upon request)
4-cloud portal: energy consumption analysis and programming
  • Multi-user and multi-system management
  • Easy programming of each device
  • Customisable operation of lighting lines according to an astronomical clock
  • Data viewed in graphic mode
  • Data downloadable in Excel format to allow further analysis and reporting
  • Public street lighting monitoring for energy efficiency optimisation
  • Control of anomalous energy consumptions in public street lighting

4-modem Lighting 2.0 monitors public lighting lines remotely from the 4-cloud web portal and manages their operation according to a customisable schedule or a built-in astronomical clock.

The GRPS connection with onboard SIM card allows the device to access the internet and to transmit all data to the 4-cloud portal.

The operation of lighting lines is carried out by two output relays, which can be programmed over the 4-cloud web portal. An optical or S0 standard interface reads energy consumptions directly from the mains meter and sends it to the 4-cloud portal. Energy managers can thus monitor energy consumptions constantly and enhance energy efficiency or timely maintenance plans.

Furthermore, the two independent relays allow developing simple energy-saving strategies such as switching on just part of the streetlamps when traffic is low.
