Evacuation path selection method for gathering crowds based on NFC and path capacity limitation

Abstract

The invention discloses a crowd evacuation path selection method based on NFC and path capacity limitation. By adopting timeliness of information transmitted through NFC between a crowd, an evacuation indication system can accurately acquire personal information from NFC modules of mobile phones of the crowd, walking speeds of people are estimated, effective evacuation paths with the path lengths increasing in sequence are sequenced, an evacuation path sequence is acquired, evacuation paths are correspondingly distributed to the different types of people one by one from the path sequence, evacuation paths with small lengths are given priority to during distribution operation, and people who can not be distributed to the corresponding path because the capacity limitation of the corresponding path is to be exceed are distributed to the next path in the evacuation path sequence. Path capacity limitation is taken into consideration, the paths with the lengths increasing in sequence are distributed to the people walking at different speeds, congestion and treading are avoided, time spent in evacuation is effectively shortened, and the survival rate of the evacuated people is improved; the crowd evacuation path selection method is wide in application range.

Description

technical field [0001] The invention relates to a path selection method, in particular to a path selection method for gathering crowd evacuation based on NFC and path capacity limitation, and belongs to the field of communication technology. Background technique [0002] With the rapid changes in the global economy, society and environment, emergencies around the world are becoming more and more frequent, such as the Beijing Miyun Lantern Festival stampede in 2004 and the Mecca pilgrims crowding and trampling in 2006. These accidents were all caused by improper emergency evacuation measures. When a disaster occurs, people tend to gather together and blindly follow the crowd and choose the same path for evacuation. Since the number of people allowed to pass through various channels at the same time is usually limited, once too many escaped people pour in, safety accidents such as congestion or even stampede will inevitably occur, causing heavy casualties. Therefore, when an...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that when a fire or other emergency occurs in an existing public place, crowds often gather together and escape blindly, causing too many people to rush into a certain escape channel at the same time, causing congestion or even trampling, resulting in heavy casualties , provide a convenient way to quickly obtain personnel information, and send it to the evacuation command system through the network communication function, estimate the walking speed of the personnel according to the received information, and assign different evacuation routes to the escaped people based on the capacity limit of the evacuation path Path, avoiding congestion or stampede, thereby improving the escape rate, based on NFC and path capacity limitation method for gathering crowd evacuation path selection
