Wisdom fire emergency lighting and evacuation indicating system
Technical Field
The invention relates to an intelligent fire emergency lighting and evacuation indicating system, and belongs to the technical field of intelligent fire protection.
Background
As is well known, the emergency lighting and evacuation indication system has a very key effect on guiding personnel on a fire scene to escape quickly, however, the existing emergency lighting and evacuation indication system can not change the escape route in real time along with the change of fire after making the escape route of the personnel according to the scene fire.
