Intelligence in distributed lighting control devices
First Claim
1. A method for distributed intelligence in facility lighting control, the method comprising:
- detecting installation of a component for a lighting device;
sensing, using a sensor, presence of occupants in a lighting control area;
receiving signal information concerning a lighting control area in a facilities system comprising a plurality of control areas, the control area comprising the lighting device, wherein the signal information includes an indication as to when the component failed, as well as information concerning power usage, number of actuations, fault detection, and predictions concerning fault states of the component, wherein fault detection comprises evaluating characteristics of an electric load of the component;
determining instructions for operation of the control area based on at least rule-based actuation logic and the received signal information, wherein the rule-based actuation logic comprises tasks associated with particular light levels;
predicting that the component is close to expiry by evaluating the number of actuations or operating hours of the component accumulated relative to a predetermined level or threshold;
determining, by a dedicated time keeper based on the signal information, a time period between installation of the component and failure of the component;
storing, by the dedicated time keeper, the time period in a database; and
providing alarms or tasks, based on the time period or the prediction that the component is close to expiry.

Abstract
Exemplary systems, methods, and apparatuses for distributed intelligence in facility lighting control are provided. A facility lighting system may be organized into multiple control areas, each of which may include one or more component devices. Each lighting control area may be associated with a control apparatus, which controls the operation of the lighting devices of the associated control area based on various types of signal information. Signal information may include information concerning local conditions or environments, as well as information from a centralized control server. Some embodiments further include monitoring the operation and predicting fault states of the lighting control area.
