摘要:
Disclosed are systems and methods for adjusting environmental conditions within a physical structure comprising a plurality of linked commissioned units. One or more occupancy sensors (140-1, 150-1) produce data indicating that a designated zone has transitioned from an unoccupied state to an occupied state. A first one or more luminaires (140-2, 150-2) associated with a first one of the plurality of linked commissioned units (120D), produces a background level of illumination within a predetermined reaction period following the production of the sensor data. The first one of the plurality of linked commissioned units transmits data indicative of the state change of the designated zone, and at least a second one of the plurality of linked commissioned units receives the data indicative of the state change, and causes at least a second one or more luminaires to alter illumination.

Multiple master modules are connected to a bus, each having bus communication logic for initiating a transaction over the bus. The bus communication logic is able to detect when the bus is busy (or apparently busy), and in response will wait before initiating a transaction of its own. Further, a distributed reset sub-system is provided, comprising an instance of a reset mechanism at each of a plurality of the master modules. Each reset mechanism recognizes a timeout condition indicative of the detected busy state being due to error, and in response performs a staged reset. This reset process first attempts a local reset which resets the respective bus communication logic of its respective master module. If the local reset fails to clear the error, the staged reset process then attempts one or more further resets to reset bus communication logic of one or more other modules connected to the bus.

Lighting units, lighting systems, and methods are described herein for automatic and decentralized commissioning of a replacement lighting unit (140, 150, 250). In various embodiments, a replacement lighting unit may receive, from one or more remote lighting units over one or more communication networks, one or more identifiers associated with the one or more remote lighting units. The replacement lighting unit may also receive, from at least one of the one or more remote lighting units over the one or more communication networks, the lighting operation parameters associated with an inoperative lighting unit. The replacement lighting unit may then selectively energize one or more light sources (258) associated with the replacement lighting unit to emit light having one or more properties indicated in the lighting operation parameters associated with the inoperative lighting unit.

A plurality of devices communicate over a bus, the devices comprising a plurality of controller devices and a plurality of second devices. Each of the controller devices is responsible for assigning one or more of the addresses including at least the address of each of a respective one or more of the second devices. A controller device comprises address allocation logic configured to assign an address to each of that controller device's respective one or more second devices, by: searching for a currently unassigned address to assign to each of the respective one or more second devices, and if an unassigned address for one of those one or more second devices cannot be found, to issue a request to at least one other of the controller devices requesting that the other controller device changes one of the one or more addresses which that other controller device is responsible for assigning.
