Abstract
A system and method are disclosed for analyzing the effectiveness of lighting control signals that result in controlling the lighting conditions in an environment or space. The lighting conditions are changed resulting in alteration of the behavior of the people in the space, including lowering sound levels or changing mental state/behavior of the people in the space. The system analyzes information, related to the response of the people in the space, to determine the effectiveness of a control signal that is used to alter the lighting conditions. The altered lighting conditions include at least one or more of altering the intensity of the lights (dims or brightens) or wavelength of the lights (color) in the space.
Claims12
A method for analysis of controlling noise levels in an indoor monitored space to determine effectiveness of control signal types, the method comprising:
- collecting a plurality of event data sets including origin of the change in noise level, wherein each event data set is associated with a change in noise level and each event data set includes at least a control signal type generated and sent to a lighting controller in response to the change in noise level;
- storing event information for the plurality of event data sets;
- analyzing the event information to determine a duration of time that the noise level fell outside a defined range after the control signal type was sent to the lighting controller;
- ranking the control signal type for each of the plurality of event data sets based on the analysis of the event information to identify which control signal type is most effective based on a shortest duration of time, which represents time needed for the noise level to return to the defined range, representing a highest ranked control signal type;
- and
- updating a control module with the ranking results for each control signal type to allow the control module to select the highest ranked control signal type that is most effective to control a future change in noise level, and alerting the future change in noise level thereby improving quality of controlling noise levels in the indoor monitored space, wherein a feedback signal is provided to alert surrounding humans through light dimming, light colors, or light flashing.
A system comprising:
- memory for storing code and information related to a plurality of changes in sound level in a controlled space that causes a sound level of each change to fall outside of a defined range;
- a processor in communication with the memory, wherein the processor executes the code and causes the system to:
- retrieve the information from memory, wherein the information includes:
- event related data for each change;
- control signal type data for each change, wherein a control signal type is generated in response to each change of the plurality of changes;
- timestamp data for start of each change of the plurality of changes based on when the control signal type is sent;
- and
- timestamp data for return of the sound level, after each change, to fall within the defined range;
- analyze the information;
- determine a duration, using the start timestamp and the return timestamp, that each sound level fell outside the defined range;
- and
- ranking, based on a shortest duration, the control signal type using the duration in order to determine the most effective control signal type of a plurality of control signal types, wherein the shortest duration represents the highest ranked control signal type as it identifies time needed for the sound level to return to the defined range, and alerting, based on the future change in noise level, a feedback signal to alert surrounding humans through light dimming, light colors, or light flashing.
