Abstract
Technologies for an emergency evacuation system include a system operator and one or more emergency lighting units located in a building. Each emergency lighting unit further includes a processor, communication circuitry configured to communicate with the system operator, and a light indicator configured to be illuminated to indicate an exit of the building.
Claims20
An emergency evacuation system comprising:
- a system operator;
- and
- one or more emergency lighting units located in a building, wherein each emergency lighting unit comprises:
- a processor;
- communication circuitry configured to communicate with the system operator;
- and
- a light indicator configured to be illuminated to indicate an exit of the building.
A method of detecting failure of an emergency lighting unit, the method comprising:
- obtaining load sensor data generated by a load sensor of the emergency lighting unit, wherein the load sensor data is indicative of an electrical load of a light indicator of the emergency lighting unit that is illuminated to indicate an exit of a building;
- evaluating, by a processor of the emergency lighting unit, the load sensor data to monitor the electrical load of the light indicator;
- detecting, by the processor, a light indicator failure in response to determining that a level of the electric load is below a threshold;
- and
- transmitting a maintenance notification to a system operator in response to detecting the light indicator failure.
A method of monitoring occupancy with an emergency lighting unit comprising a light indicator illuminated to indicate an exit of a building, the method comprising:
- obtaining motion data generated by an visual sensor of the emergency lighting unit, wherein the motion data is indicative of movement of one or more occupants present in an environment of the emergency lighting unit;
- evaluating, by a processor of the emergency lighting unit, the motion data to monitor the environment of the light indicator;
- updating, by the processor, an occupancy counter based on the evaluation of the motion data;
- and
- transmitting the occupancy counter to a system operator in response to updating the occupancy counter.
A method of broadcasting an audio alert message in a building using a plurality of emergency lighting units, each of the plurality of emergency lighting units comprising a light indicator illuminated to indicate an exit of the building, the method comprising:
- receiving, by each of the plurality of emergency lighting units, an audio command from a system operator;
- and
- playing, by each of the plurality of emergency lighting units, an audio alert message associated with the audio command in response to receiving the audio command.
