Indoor personnel evacuation method and evacuation system based on queuing network

Abstract

The invention discloses an indoor personnel evacuation method and system based on a queuing network. The system comprises a personnel position sensing module, a safety information detection module, adecision optimization module and a central controller module. According to the method, a complex evacuation network is modeled by adopting a queuing network model, the interference of redundant information is ignored, only the influence between people and the influence between people and the environment are considered, and the method is easy to implement and is close to the actual evacuation process. According to the method, an event-driven mode is adopted to solve the problem of large calculation amount in a complex network, and the calculation complexity of the system is greatly reduced. Inthe actual simulation process, the current state and the future state of the system are considered, the evacuation strategy of the system is updated through a value iteration method, it is guaranteedthat the strategy cannot stop at the local optimal solution, and the obtained evacuation strategy is globally optimal.

Description

technical field [0001] The invention belongs to the technical field of complex network systems, and in particular relates to an indoor personnel evacuation method and an evacuation system based on a queuing network. Background technique [0002] With the growth of population and the continuous acceleration of the commercialization process, the buildings are getting higher and higher, especially the interior space of public buildings such as sports and entertainment venues, commercial buildings, exhibition conference halls, science, education, culture and health buildings, office buildings and traffic buildings. As it gets bigger and bigger, it can accommodate more and more people, and the consequences of the hidden safety hazards are becoming more and more serious. If catastrophic emergencies occur, such as fires, earthquakes, etc., the safety of indoor personnel will be greatly threatened. [0003] In recent years, the frequency of emergencies around the world has been inc...

AI Technical Summary

Problems solved by technology

[0005] Similar to the barrel theory, the evacuation time of personnel depends critically on the passage capacity of certain narrow exits. The number of people passing through these narrow exits per unit time is limited, which is prone to congestion and prolongs the evacuation time.
