An emergency dredging simulation method and system for high-speed railway platform

Abstract

The invention discloses an emergency dredging simulation method and system for a highspeed railway platform. The method comprises the following steps: partitioning a navigation gridding of optimal triangulation of an environment map of the highspeed platform, computing available exits according to the safety distance between the fire disaster and the exit of the highspeed exit and counting all available exits, further computing exit cost function value of each available exit to plan the optimal exit of each passenger of the highspeed platform, and planning an optimal path to the optimal exit by the passenger according to the optimal exit and the navigation gridding based on the environment map optimal triangulation; detecting whether the collision can occur between the passengers and adjusting the velocity vector of the passenger, thereby obtaining the optimal path and velocity vector of the passenger at the highspeed platform, and obtaining a simulation result of the highspeed platform evacuation condition after the fire disaster occurs, wherein a highspeed railway evacuation scheme is customized according to the simulation result.

Description

technical field [0001] The invention belongs to the field of high-speed railways, and in particular relates to an emergency dredging method and system for high-speed railway platforms. Background technique [0002] Large-scale crowd movement simulation is to study the movement characteristics and laws of crowds in various environments, establish a large-scale crowd simulation model, and realistically display the large-scale crowd movement process in a three-dimensional manner in a computer-generated space. As an analysis tool, large-scale crowd motion simulation technology can be applied in the field of public security, and can assist in the establishment of evacuation plans for people in positive situations, rationally arrange firefighting equipment, allocate police forces, etc., and can also be used as venue management personnel for firefighting and anti-terrorism Auxiliary tool for safety program rehearsal and training. [0003] In recent years, most of the simulation re...
