Background Traditional fire-fighting evacuation indicators are mostly static "safety exit" indicator lamps, the direction of which is fixed. When a fire disaster occurs, part of marked safety outlets can be blocked actually due to fire spreading and smoke spreading, so that the safety outlets become dangerous outlets, and if people still blindly follow the static indication board to escape, the people can easily enter dangerous situations by mistake. Some existing intelligent systems can dynamically adjust the direction, but usually only change the arrow direction to carry out visual prompt or only carry out voice prompt. In emergency situations, smoke may obstruct the view causing visual arrows to be less likely to be found, and ambient noise may mask voice instructions.
