Embodiment Construction

[0025] see Figure 1 to Figure 4 , a large-scale gathering crowd counting method based on the base station visit location register, the operation steps are as follows:

[0026] (1) Estimate the wireless coverage area of ​​each base station:

[0027] Select five base stations as simulation objects, calculate the straight-line distance between a single base station and its adjacent base stations according to their latitude and longitude coordinates, select the smallest three adjacent base station distances and take the average value, and obtain the equivalent distance from the base station to the adjacent base stations D. AB , after calculating the equivalent coverage radius D of the base station according to the following equation AC :

[0028] D A C = 3 3 D A B ;

[0029...

Abstract

The present invention provides a large-scale assembly population statistics method based on a base station visitor location register, and belongs to the mobile communication field. The method is characterized in that a visitor location register (VLR) is used as a database used for storing the visiting user information in a base station mobile switching center (MSC), and store the real-time location register information of each user coming from the VLR; according to the characteristics that the capacity of the VLR is large, and the mobile terminals can register in the VLR, and the high popularizing rate of the intelligent mobile phone at present, the user number gathered by a technology can reflect the actual number of people in a specific base station cell visually; a wireless positioning technology is used to exclude the population in the buildings at the places of more buildings, and if the long-time displacements of the persons are within a small range, the persons are confirmed to be in the buildings; at the same time, an error of the number of people gathered by the VLR is reduced by adopting the number of people gathered by combining the signaling interception, and by processing the simulation data, a dynamic visual process is realized, and the number of people within the coverage range of a base station is gathered.

Description

technical field [0001] The invention proposes a large-scale assembly crowd counting method based on the base station Visitor Location Register (VLR), and designs a set of algorithms for correcting the error of counting the number of people. Background technique [0002] Stampede accidents frequently occur in large-scale gatherings in various countries. How to use effective and simple methods to count the number of people in the event gathering place, judge the movement direction of the flow of people, and take preventive and evacuation measures before the abnormality of the crowd and after the accident has become a topic of much attention. At present, there are many ways to count the crowd of large-scale gatherings in the world. The most widely used method is video image processing. However, due to the influence of weather, light and other factors, image processing is not suitable for all large-scale gatherings. [0003] Today, with the high popularity of mobile Internet and...
