During the evacuation process, people are often evacuated based on exit lights installed throughout the building.
In order to ensure that people in a building can quickly evacuate the building, generally speaking, more than one safety passage is arranged in the building, the safety exit indicator lamps pointing to different directions can point to different safety passages, and people can freely select the safety passage to be evacuated when evacuating, so that the situation that the blockage is caused in the same safety passage due to the congestion of too many people is avoided. However, in the evacuation process, since the persons always subconsciously evacuate following the first-seen indicator light, this means that the persons in the same area can select the same safe passage for evacuation. However, since the distribution of people in the building is not uniform, that is, people in some areas are densely distributed and people in some areas are scattered, for example, in daytime, there are more people in office areas in the building, and a lodging area in the building is almost nobody, and once a police situation occurs at this time, people in the building can consciously select a security passageway in the office area to evacuate, so that the security passageway is congested, and the security passageway in the lodging area may even be empty without one person, which results in the waste of resources of the security passageway in the lodging area, and at the same time, the security passageway in the office area is congested, so that the speed of evacuating people is reduced, and safety accidents easily occur, and great safety hazards exist. Therefore, in order to ensure that people can evacuate the building as soon as possible when an alarm occurs, in addition to the need for an alarm, how to realize the diversion of people becomes a problem which needs to be solved urgently.
