Existing fire fighting evacuation technologies in communities, such as chinese patent "a fire fighting evacuation method, device, computer equipment and storage medium" with publication number CN109754550A, propose to obtain the working state of fans related to the area to be evacuated when receiving evacuation instructions; determining an emergency evacuation route according to the working state of the fan; and sending a control instruction to each target indicator lamp based on the emergency evacuation route, and controlling each indicator lamp to carry out evacuation indication based on the emergency evacuation route. A dynamic generation method, a system and an electronic terminal for a crowd emergency evacuation route of a Chinese patent with a publication number of CN108596812A, which proposes to collect environment and crowd data by using a distributed computing network deployed in a place; adopting a decentralized reverse chain method to decide an optimal path; and the personnel sequentially pass through the optimal route according to the indication, and modify and update the evacuation route in real time according to the real-time position of the personnel, the disaster spreading and spread range, the road condition and the personnel density in the current environment in the personnel execution process until the personnel reach the evacuation target area. In chinese patent "an evacuation lighting guide device" with publication number CN206478530U, it is proposed that a lighting lamp, an alarm device, LED lamp beads and a smoking fan are controlled by a single chip, so as to reduce indoor smoke concentration, indicate direction for a security exit, and the alarm device gives an alarm, so that people cannot escape from the front clearly because of too high smoke concentration indoors. Chinese patent CN202995948U, a dynamic escape guidance system for fire based on intelligent path, proposes that multiple striking dynamic light paths are formed in smoke by using the characteristics of high laser brightness, strong penetrability and easy identification, so that the guidance system is easy to identify, and solves the defect that the currently used guidance equipment cannot effectively guide in smoke environment; and the central control unit is used for realizing real-time dynamic monitoring of the building, and the optimal evacuation and rescue route is intelligently calculated by combining information such as a built-in electronic building map, a guiding strategy and the like, and the laser guiding equipment is controlled to work, so that people are safely and rapidly guided to evacuate and evacuate.
In the technology, the evacuation route is calculated according to the map of the building and is guided by the indicator lamp or the laser, the influence of indoor smoke and structural change on road traffic is not considered, dangerous conditions that the indicated evacuation road is blocked by smoke or collapsed and blocked by construction in the building or blocked by structural change of the building and the like are possibly caused, the evacuation route is difficult to replace in time, and the danger that people cannot evacuate in time is caused.
