Embodiment Construction

[0019] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be further described in detail below in conjunction with the drawings and specific embodiments.

[0020] Such as figure 1 As shown, the present invention provides a kind of real-time passenger flow statistics method based on WIFI probe data, and its specific steps are as follows:

[0021] 1. Within a day, after the WIFI hotspot device in a store collects WIFI probe data, it will store the WIFI probe data in the server. It is counted together with the store ID, and the number of occurrences of the same mac address in different stores is counted separately. In order to speed up the processing speed, the smaller the value of field strength RSSI is, the closer the mac address is to the WIFI hotspot device. Count the number of RSSIs of each level, and then remember that the mac addre...

Abstract

The invention discloses a real-time passenger flow statistical method based on WIFI probe data. The method comprises the following steps: collecting the WIFI probe data of a store within one day, storing the WIFI probe data in a server, and counting the WIFI probe data by the server; S2, screening the WIFI probe data by the server for filtering mac addresses not satisfying a passenger flow number calculation rule; S3, performing counting on the mac addresses left after the screening by the server, wherein the number of the corresponding mac addresses is the passenger flow number; in the passenger flow number, if the mac addresses of the passenger flow number are not recorded as the mac addresses of the passenger flow number before today, recording the mac addresses as store entry people number, and counting the number of the store entry people number; and S4, when one day is ended, performing permanent storage on the data of the passenger flow number and the store entry people number by the server. By adoption of the real-time passenger flow statistical method disclosed by the invention, the flowing people in the store can be accurately counted, and the real-time passenger flow statistical method has the advantages of high instantaneity, high calculation speed, accurate statistics, etc.

Description

technical field [0001] The invention relates to the technical field of mobile devices being used to count crowds, in particular to a real-time passenger flow counting method based on WIFI probe data. Background technique [0002] Mobile devices such as mobile phones, tablets, etc., need to send Probe request probe data packets when accessing the WIFI network. These data packets contain the MAC address information of the terminal. By designing special routers and other devices, the mac address of the terminal can be obtained , field strength RSSI, and current time information. WIFI probe data can be applied in the fields of early warning of large crowds, indoor positioning and trajectory analysis. Usually, these applications are carried out by collecting mac address information collected by routers and counting the signal strength of a certain mac address within a period of time. [0003] With the advancement of technology, major merchants now provide WIFI in their stores fo...
