Early warning system for non-specific crowd flow temporary aggregation points based on block chain

Abstract

The invention discloses a blockchain-based non-specific crowd flow temporary aggregation point early warning system, which comprises a distributed system, a data collection center, a user point construction module, a map database, a gridding module, a real-time map display module and a threshold setting module, and is characterized in that the distributed system acquires user information and position information of each user; the data collection center acquires user information and position information; the real-time map display module displays a map of the early warning area; the gridding module divides the map of the early warning area into grid maps; the user point construction module is used for constructing user points of each user and adding the user points into each grid map; the threshold setting module is used for setting a crowd number threshold for each grid map; and when the number of the user points on a certain grid map exceeds a crowd number threshold, the real-time mapdisplay module gives an alarm. Therefore, real-time monitoring and early warning can be carried out, and prediction and early warning can also be carried out.

Description

technical field [0001] The invention relates to the fields of block chain technology and early warning technology, in particular to an early warning system based on block chain temporary gathering points for non-specific crowd flow. Background technique [0002] Unfixed crowds are formed due to the free flow of holidays or specific events, forming a temporary large-scale gathering. Because of unpredictability, the gathering point is not fixed, it is impossible to set up effective protective measures in advance, and it is impossible to arrange staff in time, which is prone to group stampede and other accidents . Therefore, it is necessary to design an effective early warning system for this non-specific crowd flow and gathering. [0003] In addition, blockchain is a new application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Because of its characteristics, applying it to the abov...
