T-Light Galaxy DCU (star network)

Telematics T-Light Galaxy DCU

T-Light DCU Galaxy is a principal component of the T-Light Galaxy long-range street light control network.

DCU Galaxy is installed on a strategically chosen site with a high antenna, and can control up to 50,000 light poles within a radius of up to 30 kilometres.

The Data Communication Unit (DCU) uses robust and encrypted two-way communications to manage information traffic and commands for both individual lighting units and for groups of lights. Storing all status and energy consumption information of the remote Luminaire Control Units (T-Light LCU), the DCU communicates with the Central Management Software (using TALQ protocol) and transmits all control commands to the luminaires. The DCU provides the monitoring status of each luminaire, including aggregative energy and active power consumption. It provides detailed parameters and values, such as voltage, current, power and temperature and is capable of other SMART functions (movement, noise and other sensors etc).
