Abstract
Disclosed are a system and method for developing computational models of the behavior of a building's occupants using data acquired from sensor-equipped connected luminaires. The models are then used to develop an optimized evacuation plan for safe and timely egress of the occupants without requiring mock evaluation drills.
Claims15
A system for evaluating evacuation plans for occupants of a building, the system comprising:
- a plurality of luminaires and a plurality of sensors each plurality being installed at locations throughout the building, at least some of the plurality of sensors in communication with at least one luminaire, wherein each of said plurality of luminaires being configured to communicate with at least one other luminaire to form a network, wherein the networked luminaires form a unified sensor network;
- a processor configured to receive an evacuation plan for the building, collect sensor occupancy/motion data from the plurality of sensors prior to an evacuation event, model the occupants' movements between different parts of said building using the sensor occupancy/motion data, wherein the model includes determining a transfer rate of occupants' movements between different parts of said building, and use the models to modify the evacuation plan if the transfer rate is to fast or slow based on a predetermined criteria.
A method for operating a system of networked sensor equipped lights installed in a building to develop an evacuation plan for one or more parts of the building, the method comprising:
- receiving an evacuation plan for the building;
- detecting the presence of occupants in different parts of the building;
- collecting sensor occupancy/motion data from the plurality of sensors prior to an evacuation event;
- modelling occupants' movements between said different parts of said building using the sensor occupancy/motion data;
- determining a transfer rate of occupants' movements between different parts of said building using the model from the modelling step;
- modifying the evacuation plan if the transfer rate is to fast or slow based on a predetermined criteria.
A computer-readable, non-transitory medium having stored therein instructions for causing a processing unit to execute a method for operating a system of networked sensor equipped lights installed in a building to develop an evacuation plan for one or more parts of the building, the medium comprising code for:
- receiving an evacuation plan for the building;
- receiving sensor occupancy/motion data regarding the presence of occupants in different parts of the building from a plurality of sensors prior to an evacuation event;
- modelling occupants' movements between said different parts;
- developing an optimized evacuation plan for the occupants based on the results of said modelling step.
