Grouping wireless lighting nodes according to a building room layout
First Claim
1. A method for determining the relative locations of a plurality of nodes within a building, the nodes including a plurality of wirelessly-controllable service device nodes and a plurality of switching control nodes, at least some of the service device nodes being located in different rooms of the building with respect to each other, the method comprising:
- establishing wireless communication between the nodes to determine relative spatial positions of the nodes using received signal strength indication (RSSI) values each indicative of a distance of separation between two of the nodes;
grouping the service device nodes into at least two groups, including a first group of the service device nodes located in a first one of said different rooms, and a second group of the service device nodes located in a second one of said different rooms, based on a spatial distribution of the nodes as indicated by the RSSI values; and
allocating the service device nodes of the first group to have a switching operation thereof controlled by a first of the switching control nodes, and allocating the service device nodes of the second group to have a switching operation thereof controlled by a second of the switching control nodes.

Abstract
A method determines the relative locations of wirelessly controllable service device nodes and switching control nodes within a building. At least some of the service device nodes are located in different rooms of the building and should be allocated to switching control nodes on a room-specific basis. Wireless communication is established between the nodes to determine relative spatial positions of selected nodes using received signal strength indication (RSSI) values indicative of a distance of separation between two communicating nodes. The service device nodes are then grouped into two or more groups, a first group corresponding to service device nodes in one room and a second group corresponding to service device nodes in a second room, based on spatial distribution of the service device nodes as indicated by the RSSI values. The service device nodes of each group are then allocated to at least one associated switching control node.

14. An apparatus for allocating plural wirelessly controllable service device nodes to appropriate switching control nodes within a building, at least some of the plural service device nodes being located in different rooms of the building with respect to each other, the apparatus comprising:
-
transceivers for establishing wireless communication between;
(1) a first node comprising one of the service device nodes, or one of the switching control nodes, or a gateway node in communication with a building management system for the building; and
(2) second nodes comprising each of the service device nodes that is within communication range of the first node, to determine relative spatial positions of the first node and the second nodes using received signal strength indication (RSSI) values indicative of distances of separation between the first node and the second nodes, wherein at least one of the service device nodes includes one of the transceivers;a microprocessor for grouping the service device nodes into at least two groups, including a first group corresponding to service device nodes located in a first one of said different rooms, and a second group corresponding to service device nodes located in a second one of said different rooms, based on spatial distribution of the second nodes as indicated by the RSSI values; and allocation means for allocating the service device nodes of the first group to have a switching operation thereof controlled by a first of the switching control nodes, and for allocating the service device nodes of the second group to have a switching operation thereof controlled by a second of the switching control nodes. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A switching control node, comprising:
-
a transceiver for establishing wireless communication between the switching control node and a plurality of lighting nodes to determine relative spatial positions of the lighting nodes using received signal strength indication (RSSI) values each indicative of a distance of separation between the switching control node and one of the lighting nodes; a microprocessor for grouping the lighting nodes into at least two groups, including a first group corresponding to lighting nodes in one room of a building, and a second group corresponding to lighting nodes in another room of the building, based on spatial distribution of the lighting nodes as indicated by the RSSI values; and allocation means for allocating the lighting nodes of the first group to have a switching operation thereof controlled by the switching control node and for not allocating the lighting nodes of the second group to have a switching operation thereof controlled by the switching control node.
