Abstract

The invention relates to a power distribution system (1), especially a Power-over-Ethernet system, comprising at least one dominant sensor, which may be located within a powered device (4) like a lighting device, and at least one non-dominant sensor, which may be located within another powered device (4), wherein the power distribution system is adapted such that in a system low power mode the at least one dominant sensor (6) consumes power provided by a power providing unit (3) and the at least one non-dominant sensor (6) does not consume the provided power and that the power distribution system (1) switches from the system low powermode to a system high power mode, if the at least one dominant sensor (6) has sensed an event. Since in the system low power mode the at least one non-dominant sensor does not consume power, the power consumption can be reduced.

Claims

1. A Power over Ethernet (PoE) power distribution system comprising:

a Power Sourcing Equipment (PSE), having several ports, for providing power,

sensors, each sensor comprised in a Powered Device (PD) connected via an Ethernet cable to a port of the PSE, for sensing an event,

an assignment providing unit for providing assignments assigning at least one sensor, of the sensors, to a dominant class, thereby defining at least one dominant sensor, and assigning at least one other sensor, of the sensors, to a non-dominant class, thereby defining at least one non-dominant sensor,

wherein the PoE power distribution system is operable in a system low power mode, in which the PoE power distribution system consumes less power, and a system high power mode, in which the PoE power distribution system consumes more power, wherein the PoE power distribution system is adapted such that in the system low power mode the at least one dominant sensor consumes power and the at least one non-dominant sensor does not consume power and that the PoE power distribution system switches from the system low power mode to the system high power mode, if the at least one dominant sensor has sensed an event,

wherein the PoE power distribution system is adapted such that in the system low power mode a port of the PSE to which a non-dominant sensor is connected is switched off.

2. The PoE power distribution system as defined in claim 1, wherein the sensors include a presence sensor and/or a temperature sensor and/or a light sensor and/or humidity sensor and/or a gas sensor.

3. The PoE power distribution system as defined in claim 1, wherein the PoE power distribution system further comprises electrical loads being adapted to consume power provided by the PSE, wherein the electrical loads include a light source and/or an air conditioning device.

4. The PoE power distribution system as defined in claim 1, wherein the PoE power distribution system further comprises electrical loads being adapted to consume power provided by the PSE, wherein at least one Powered Device comprising a sensor further comprises at least one electrical load.

5. The PoE power distribution system as defined in claim 1, wherein the PoE power distribution system is further operable in a learning mode in which the sensors are powered for sensing an event and in which a learning process is performed for assigning a sensor to the dominant class, wherein the assignment providing unit is adapted to assign a sensor, which firstly senses an event after the learning process has been started, to the dominant class.

6. The PoE power distribution system as defined in claim 5, wherein the assignment providing unit is further adapted to assign at least one further sensor to the dominant class, if the at least one further sensor has sensed an event within a predetermined time interval starting from the time of the first sensing of the event after the learning process has been started, in order to assign several sensors to the dominant class.

7. The PoE power distribution system as defined in claim 5, wherein the PoE power distribution system is adapted to perform the learning process several times, in order to assign different sensors to the dominant class.

8. A Power Sourcing Equipment (PSE) for providing power to sensors of a PoE power distribution system as defined in claim 1, wherein the Power Sourcing Equipment is adapted to be used by the PoE power distribution system.

9. An assignment providing unit for providing assignments assigning at least one sensor of the PoE power distribution system as defined in claim 1 to a dominant class, thereby defining at least one dominant sensor, and assigning at least one other sensor of the PoE power distribution system to a non-dominant class, thereby defining at least one non-dominant sensor, wherein the assignment providing unit is adapted to be used by the PoE power distribution system.

10. An overall system comprising several PoE power distribution systems as defined in claim 1, wherein the sensors of different PoE power distribution systems of the overall system are arranged in different spatial regions.

11. A Power over Ethernet (PoE) power distribution method for distributing power within a PoE power distribution system as defined in claim 1, wherein the PoE power distribution method comprises:

consuming, in the system low power mode, power by the at least one dominant sensor and not by the at least one non-dominant sensor, by switching off a port of the PSE to which a non-dominant sensor is connected,
