Background
In modern large commercial buildings, there are often complex grid-like passages within the floors. In this case, a great obstacle is brought to escape of people in case of fire.
After a fire occurs, it should escape from the fire scene for the first time. Due to high temperature, dense smoke, toxic and harmful gases and the like caused by fire, the staying time of people in a fire scene is very short, and is only about 90 seconds. Personnel may be life threatening if they cannot find an exit from the fire in 90 seconds. In order to establish a fast and orderly fire escape order, all people need to be notified of a fire alarm at the first time, and reasonable escape route information is provided for each person at the fastest speed. Among them, the second point is most difficult to achieve. Because evacuation channels are numerous and the fire scene situation is complex, not all normally smooth channels can be used at the moment; if the fire point blocks the channel, the high temperature and the dense smoke generated by the fire point can cause more harm to surrounding people; because of numerous people and different positions of different people, the corresponding optimal escape routes are different, and route guidance for each person cannot be realized through large-area broadcasting. In practical applications, there is also little solution for the second point.
At present, the functions of fire-fighting emergency indicator lamps on the market are generally single, the emergency escape indication direction is fixed, and the emergency indication direction cannot be flexibly adjusted. When a fire occurs, the escape direction cannot be flexibly and correctly indicated according to the place where the fire occurs and the number of evacuees.
