Method, system and electronic terminal for dynamic generation of crowd emergency evacuation route

Abstract

The invention discloses a method, a system and an electronic terminal for dynamic generation of a crowd emergency evacuation route. The method comprises the following steps: S1, collecting environmentand crowd data by utilizing a distributed computing network deployed in a place; S2, carrying out decision making on an optimal route by adopting a decentralization backward chaining method; and S3,enabling personnel to sequentially go through the optimal route determined by the step S2 according to instructions, and in a personnel executing process, modifying and updating an evacuation route inreal time according to real-time positions of the personnel as well as disaster spreading ranges, road conditions and density of the personnel in the current environment until the personnel arrives at an evacuation target area. The method, system and electronic terminal solve the problems that real-time performance is low and a network load of a center node is large in the prior art.

Description

technical field [0001] The invention relates to the field of building security Internet of Things, in particular to a method, system and electronic terminal for dynamically generating emergency evacuation routes for crowds. Background technique [0002] In recent years, research on intelligent evacuation systems has achieved some results. Intelligent evacuation systems can provide evacuated people with safe and fast evacuation methods to evacuate disaster areas, reducing the loss of personnel and materials. In the latest intelligent evacuation method, when selecting the evacuation route, in addition to factors such as smoke, toxic gas, and heat, crowd density, crowd category, and the time-space mobility model of the crowd are also incorporated. Crowds in the area provided an alternative evacuation route, alleviating road congestion. In addition, the current cloud-based fire evacuation system can determine the best evacuation route for each person by detecting the RFID tag o...
