[0029] The establishment of the Android mobile client includes:
[0030] The invention uses the Android development platform to create an Android project, which can be divided into four parts: the main interface, the WiFi scanning part, the database part, and the matching algorithm part.
[0031] The main interface part: The mode of combining buttons and dialog boxes is adopted, which reflects friendly human-computer interaction. Its interface is like Figure 5 . A total of 3 text boxes (that is, 1 uneditable and 2 editable text boxes), 6 buttons, and 1 list are used in this system. The 2 editable texts are used to input the horizontal and vertical coordinates of the current position, which are used for fingerprint collection and positioning. The data type is double precision. The 6 buttons are "Receive and display calculation results", "Store fingerprint information", "Delete fingerprint information", "Display database information", "Start positioning", and "E...

[0042] In the positioning stage, the present invention performs data analysis on different times of wireless signal scanning; when the scanning times are the same, multiple experiments are performed to obtain the average value, and an optimal method is adopted for data processing. In the positioning client, it is displayed on the screen of the mobile terminal in a friendly manner.
[0043] First, use the Android development platform to develop mobile positioning clients and AP signal collection tools. This system is mainly divided into WiFi signal collection phase and positioning phase. The overall system architecture is as follows figure 1 As shown, the flowcharts of the WiFi signal collection phase and the positioning phase are as follows: figure 2 , 3 Shown.
[0044] 1. The WiFi signal collection module mainly includes the following:
[0045] 1) The distribution of data collection points. At present, most indoor shopping malls use square tiles, so the collec...
