Single-layer building emergency personnel evacuation path planning method, building structure design optimization method, computer equipment and storage medium

Abstract

The single-layer building emergency personnel evacuation path planning method comprises the following steps: obtaining structure information of a single-layer building, and generating building structure constraint conditions containing a plurality of path nodes based on the structure information, and specifying a starting point and an ending point in the path nodes; constructing personnel moving speed constraint conditions based on visibility, toxic gas concentration, smoke temperature and personnel density; constructing a coupling path planning algorithm based on A* algorithm and particle swarm optimization algorithm, and cross optimizing the A* algorithm and the particle swarm optimization algorithm; introducing the building structure constraint conditions and the personnel moving speed constraint conditions into the coupling path planning algorithm, and generating an optimal evacuation path by using the coupling path planning algorithm. The emergency personnel evacuation path planned by the method has lower total time steps and average moving distance of all personnel successful evacuation, is more scientific and reliable, and can screen different single-layer building structure design schemes to select a more optimal single-layer building structure design scheme.
