Controlling system for controlling a power/data-communication system
First Claim
1. A controlling system for controlling loads of a power/data-communication system, wherein the controlling system comprises:
- a command providing unit for providing a command defining desired power levels of loads of the power/data-communication system,an overall power change determination unit for determining an overall power change amount caused by the provided command, based on the provided command,a control unit for controlling the loads such that a slope of an overall power consumption of the loads, when being set to the desired power levels, is reduced, if the determined overall power change amount is larger than a predefined power change threshold,wherein the control unit is adapted to subdivide an individual power change amount, which is needed for a respective load for reaching the respective desired power level, into individual power change sub-amounts and to control the respective individual load such that its power level is changed in accordance with the respective individual power change sub-amounts at different times.

Abstract
The invention relates to a controlling system (4) for controlling loads (2), especially lighting units, of a power/data-communication system like a PoE system, wherein a command is provided, which defines desired power levels of loads of the power/data-communication system. An overall power change amount is determined, which will be caused by the provided command, and the loads are controlled such that the slope of the overall power consumption of the loads, when being set to the desired power levels, is reduced, if the determined overall power change amount is larger than a predefined power change threshold. Thus, if the provided command may lead to an overall power change amount causing problems like blown fuses, the loads are controlled such that the slope of the overall power consumption of the loads, when being set to the desired power levels, and hence the likelihood of, for instance, blown fuses is reduced.
