Layout of an extended light management system

The resulting layouts of the competing technologies are very often similar. The luminaire is equipped with a local smart controller which as far as possible can take over all control functions independently. Communication between the controller and the data concentrator is bidirectional via powerline. At this point, very different considerations are made as especially the questions relating to standardisation, openness and the resulting sustainability of the investment cause discussions.
The LiCS outdoor system uses the powerline data transmission technology that is based on an EN/ISO standard and, accordingly, very clearly allows competition. The most varied functions are assigned to the data concentrator, or iDC for short, which as can already be derived from the term has a central role within the system. Due to the necessary redundancy, the iDC is equipped with a real-time clock as the possibility that communication up to the service centre may be disrupted has to be taken into account. In that case, a local switching-time program takes over control and ensures that the lighting system will still function. In the direction of the service centre, the iDC takes over the preprocessing of the data. Data is preprocessed after logging/intermediate storage, i.e. checked for limit value violation and then transmitted in concentrated form to the operation control centre during the morning hours.
At the service centre, the operator has a comprehensive overview of the lighting system every day when work starts with data on luminaire failure, non-compliance with limit values such as temperature, voltage, current, power, power factor and, of course, energy consumption. From this operation control centre, special programs may be configured at any time that allow the lighting system to be controlled differently.
