Smart Public Lighting

Street lighting switching by an automatic operated or the electricity supplier requested controlling system.lcb_solution1_web

By using this system, it is possible to optimize the service and decrease the operation costs of the infrastructure.

The solution is useful for controlling smart grids, central switching, monitoring and manage of critical infrastructures.

Decreased amount of data transmitting through the future-proof LTE narrow-band mobile network standards. The network grid is assured by the industrial routers (M2M Router®) to provide an enclosed network for the communication of the switching devices.

Load Control Management due to the Intelligent Load Control Box (LCB) when switching on/off – by the relays of the device – the consumers/producers from head-end-system.
The scheduled switching is followed by the programmed calendar, whereas the operation depends on weekdays, dawn and dusk times of the year, and the geographical position.

Well manageable, high-secure and reliable communication network due to the M2M Device Manager, which assures scalable grid management to connect the switch devices – through the routers – for the head-end system.
Central device and network parameters monitoring, data collection and analysis are provided by the system for futher benefits of the energy provider.

The device management features are available at nay time in case of a failure or manual intervention. The aggregate software updates, device configuration distribution for the endpoint devices are also possible remotely from the centre.

Street Light Failure Monitoring

Monitoring solution for transformer stations of the energy supply and for street lighting.lcb_solution2_web

It is useful for central electricity management, smart grid maintenance, monitoring and outage management of the critical infrastructures.

The measured data of the connected electricity meters are transmitted – by some of the WM-E modems family members – to the data center.

The head-end-system is continuously monitoring the energy consumption. The possible outages, consumption reductions or unexpected falls of the energy usage during the operation hours are automatically reported to the center.

The solution uses a standard, open protocol platform, with a spectacular open source user interface with data analysis and report opportunities.
