Embodiment 1

[0073] Such as image 3 and Figure 4 Shown, the WIFI device location tracking method that is used for retail trade of the present invention, the location method to each WIFI equipment in step (2) further comprises:

[0074] (21) Each WIFI device periodically broadcasts the data frame of its own ID;

[0075] (22) Each relay station receives the data frame wirelessly broadcasted by each WIFI device, and selects the first three relay stations from large to small according to the received signal strength value RSSI;

[0076] (23) Determine the distance values ​​r1, r2, r3 of the WIFI equipment to be located from the three relay stations according to the signal strength value RSSI; the method for determining the distance value of the WIFI equipment to be located from the relay station can adopt the following formula:

[0077] r=0.1*RSSI 2 +10*RSSI+236

[0078] Wherein, r is a distance value, and RSSI is a signal strength indicator value.

[0079] (24) Taking the three relay s...

Embodiment 2

[0085] The difference from Embodiment 1 is that the positioning method of step (2) uses more than three relay stations to detect and correct the position of the same WIFI device. Various methods can be used for each relay station to detect the position of the WIFI device. For example, each relay station can also use wireless The phase difference of the signal detects the position of each WIFI device. Multiple relay stations perform correction and precise positioning based on the detected location of WIFI devices.

[0086] In addition, other principles and methods can also be used by the relay station to locate the WIFI device. The research on related positioning algorithms is very mature at present, and this application will not elaborate here.

Embodiment 3

[0088] Such as Figure 5 Shown, the WIFI device location tracking method that is used for retail trade of the present invention, the data analysis that step (3) carries out can be for the management of customer traffic, then specifically comprise the following steps:

[0089] (31) Detect the number of WIFI devices around each relay station;

[0090] (32) Determine the flow of people in the area channel according to the number of WIFI devices around each relay station;

[0091] (33) Calculate the shopping guide traffic map according to the flow of people in each relay station area, and display the shopping guide traffic map in the area on the screen or send it to each WIFI device.

[0092] Preferably, the WIFI device location tracking method for retail trade of the present invention also includes after step (33):

[0093] (34) Determine whether the number of WIFI devices in each area exceeds the limit, if so, give a warning on the display in the overrun area, or send a warnin...

Abstract

The invention discloses a WIFI device positioning tracking system used for retail industry. The WIFI device positioning tracking system comprises a database which is used for storing customer information and data analysis information; a server which is connected with the database and multiple relay stations and used for analyzing a WIFI position; the multiple relay stations with WIFI which are connected with each WIFI device within the located area range so that the position is determined; and the multiple WIFI devices with installation of application programs. The invention discloses a positioning tracking method comprising that: (1) each relay station searches the WIFI devices in an administration area; (2) the position and stay time of each WIFI device are sent to the server; and (3) data analysis is performed by the server, and then data are stored in the database. The aforementioned steps are performed in a cycle way. Retail industry customers can be conveniently positioned and tracked so that various valuable data can be analyzed and researched, tracking of the specific customers is realized, exhibition section sales volume classification is realized, the customers are dredged according to customer flow rate, and shopping guidance is realized according to areas.

Description

technical field [0001] The invention relates to a comprehensive management system for commercial analysis data acquisition, customer shopping guide, VIP customers and retail anti-theft in the retail industry, in particular to a WIFI device positioning and tracking system for the retail industry. The present invention also relates to a WIFI device positioning and tracking method for retail business based on the above system. Background technique [0002] For a long time, retail shopping malls have needed to analyze and research various data, such as how to classify customers, track VIP customers, how to prevent theft in shopping malls, how to update promotional information, and so on. There are usually related researches on specific branches. For example, a common method is to use face recognition technology to install cameras in specific areas to capture VIP customers. The above methods are technically difficult, costly to implement, and have low accuracy. [0003] With th...
