Embodiment Construction

[0064] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are invented.

[0065] It should be noted that, in this document, relative terms such as "first", "second", and "third" are only used to distinguish the same names, and do not imply the relationship or order between these names.

[0066] In 2G cellular wireless systems, regular hexagons are usually used to abstractly describe cells. Taking a cell as an example, the cell base station is located in the center of the cell. The antenna of the cell base station provides wireless signal coverage for the cell, and the wireless signal coverage is a regular hexagon. The corresponding area range, that ...

Abstract

The invention discloses a pedestrian flow congestion early-warning method and device, and the method comprises the steps: obtaining the base station communication positioning data of a target cell ata current pedestrian counting moment; determining a first number of UEs in a target cell at the current pedestrian counting moment based on the identification of each UE in the communication positioning data; determining a third number of UEs in the target cell at the current pedestrian counting moment based on the first number of UEs and the pre-determined second number of UEs in the target cellat the current pedestrian counting moment; and determining whether to carry out the pedestrian flow congestion early warning at a next pedestrian counting moment or not based on the third number of UEs, the first number of UES and a preset UE number threshold value for the pedestrian flow congestion early warning. According to the invention, the predicted value of the number of UEs in the target cell in the next pedestrian counting moment is determined based on the actual value and predicted value of the number of UEs in the target cell at the current pedestrian counting moment, and then the predicted value is compared with a preset UE number threshold value, so as to determine whether to carry out the pedestrian flow congestion early warning, and to solve a problem of accidental pedestrian congestion.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for early warning of crowd flow congestion. Background technique [0002] With the continuous development of the economy, the continuous advancement of science and technology, my country's urbanization process is advancing rapidly, and the urban population continues to hit new highs, resulting in excessively dense and disordered crowds in public places such as transportation hubs, subways, large-scale event sites, and tourist attractions. flow, which leads to more and more difficulty in the management of public places, and it is easy to cause a series of crowd flow (referred to as flow of people) congestion problems such as extrusion and stampede. [0003] At present, there are mainly the following methods for early warning of crowd flow congestion: [0004] Method 1: Manual intervention. Before large-scale events such as large-scale competitions and e...
