Commissioning of a building service system
View Patent ↗The invention relates to adjusting at least one of installed building service sensors ( 10 ) of a building service system. A sensor coverage area of at least one sensor ( 10 ) is adjusted based on information on a position of the installed sensor ( 10 ) relative to at least one other sensor ( 10 ). For example, to determine the position of the sensor ( 10 ) relative to said at least one other sensor ( 10 ), each sensor ( 10 ) establishes a wireless communication between said sensor ( 10 ) and at least one other sensor ( 10 ) via a wireless communication means ( 34 ) of the sensor ( 10 ). For example, information on the positions of the installed sensors ( 10 ) is used to assign to each sensor ( 10 ) at least one of installed building service supply devices ( 12 ) of the system.
1. Method of adjusting at least one sensor of installed building service sensors of a building service system, the method comprising the step of:
automatically adjusting a sensor coverage area of said at least one sensor, the adjusting of the sensor coverage area of each sensor of said at least one sensor being based on information on a position of the sensor relative to at least one other sensor of the installed building service sensors,
wherein each of said at least one sensor comprises at least one switchable element comprising a plurality of liquid crystal display elements, said plurality of liquid crystal display elements disposed between an input sensing element of said sensor and the sensor coverage area of the sensor, for masking sensor input of said sensor, and the step of automatically adjusting a sensor coverage area comprises controlling the at least one switchable element of each of said at least one sensor in order to adjust the sensor coverage area of the sensor, and
wherein in each sensor of said at least one sensor, the plurality of liquid crystal display elements are arranged in at least a two-dimensional pattern.
2. Method as claimed in claim 1 , wherein the system further comprises at least one of installed building service supply devices, the method further comprising the step of:
using information on the position of said at least one sensor to assign to each of said at least one sensor, at least one of the installed building service supply devices.
3. Method as claimed in claim 2 , wherein the at least one of installed building service supply devices is selected from the group consisting of one or more of luminaires, heating units, ventilation units and air conditioning units.
4. Method as claimed in claim 1 , wherein in the step of automatically adjusting a sensor coverage area of said at least one sensor, the sensor coverage area of each sensor of said at least one sensor is adjusted based on information on a position of the sensor relative to at least a nearest neighboring sensor of the installed building service sensors.
5. Method as claimed in claim 1 , wherein, in the step of automatically adjusting a sensor coverage area of said at least one sensor, the sensor coverage area of each of said at least one sensor is adjusted based on a map of a spatial arrangement of at least said at least one installed sensor of the installed building service sensors.
6. Method as claimed in claim 1 , wherein in the step of automatically adjusting a sensor coverage area of said at least one sensor, each sensor of said at least one sensor performs the step of:
adjusting a sensor coverage area of the sensor based on information on a position of the sensor relative to at least one other sensor of the installed building service sensors.
7. Method as claimed in claim 1 , wherein each of said at least one sensor comprises a wireless communication unit, the method further comprising the step of:
each of said at least one sensor establishing a wireless communication between said sensor and at least one other building service device of the building service system via the wireless communication unit of the sensor to determine said position of the sensor relative to said at least one other building service device.
8. Method as claimed in claim 1 , wherein said installed building service sensors comprise any one or more of presence detection sensors, movement sensors, temperature sensors, and daylight sensors.
9. Method as claimed in claim 1 , wherein said installed building service sensors comprise optical sensors.
10. Method as claimed in claim 1 , wherein the controlling comprises controlling the plurality of liquid crystal display elements to alter an input angle of the sensor coverage area.
11. Method as claimed in claim 1 , wherein, in each sensor of said at least one sensor, the plurality of liquid crystal display elements are arranged in at least one ring.
12. Method as claimed in claim 11 , wherein said at least one ring is a plurality of concentric rings, and wherein each ring of said concentric rings is composed of a different, respective set of the liquid crystal display elements.
13. Method as claimed in claim 12 , wherein each ring denotes a different, respective input angle of the sensor coverage area and wherein the adjusting of the sensor coverage area comprises setting the sensor coverage area to a given input angle corresponding to a given set of said sets of the liquid crystal display elements by activating the ring composed of the given set.
