In order to understand the present application more clearly, the following will describe the application scenario of the electronic price tag with reference to FIG. 1 . It should be noted that the scenario in Figure 1 is only illustrative and not limiting. As shown in Fig. 1, when the user is shopping in the supermarket, the electronic price tag 10 can display the name, price and QR code of the commodity. The user can intuitively know the commodity price through the electronic price tag. If the user wishes to know more commodities To obtain information or perform some specific operations (for example, payment) on the commodity, the QR code in the electronic price tag can be scanned with a mobile terminal such as a mobile phone 20 as shown in FIG. 1 .

As shown in FIG. 3 , the data processing system includes a mobile terminal 310 , an electronic price tag server 320 and one or more electronic price tags 330 . When the user enters the room (for example, a supermarket) with the mobile terminal 310, the electronic server 320 may send reminder information to the mobile terminal to remind the user to start the communication switching operation, for example, by pushing “whether to enable the search mode” or “whether to enable the search mode” to the user. Whether to locate” and other information to remind the user to start the communication switching operation.

Subsequently, the user may perform a communication switching operation of switching the communication mode of the mobile terminal 310 to the broadcast mode on the display interface of the mobile terminal 310 . For example, the Bluetooth module in the mobile terminal can be made to operate in a broadcast mode. The triggering operation of the user may be various input operations, for example, it may be triggered by the "touch" operation mentioned above, or may be triggered by voice input or may be triggered by vibration.

In an implementation, when compared with the strength signal values in the received signal strength distribution information, two values within a predetermined error range may be equal.

After the location of the mobile terminal 310 is determined, the location of the mobile terminal 310 can be combined with the location of the electronic price tag to provide a more convenient shopping experience to the user.

Although there is only one mobile terminal 310 in FIG. 3 , in practice, the data processing system can have multiple mobile terminals.

Since each data packet contains the MAC of the corresponding mobile terminal, the electronic tag receives the corresponding When the data packet is used, the MAC in the data packet can be extracted, and the MAC and the corresponding received signal strength can be sent to the server 320. After the server 320 determines the positions of these mobile terminals by using the received RSSI, the positions of these mobile terminals are determined according to the respective MACs. sent to these mobile terminals respectively.

Specifically, commodities within a predetermined range of the mobile terminal may be determined, and commodity information corresponding to these commodities may be sent to the mobile terminal. In addition, the user can search for commodities on the mobile terminal according to the search information, at this time, the server 320 can determine the commodity corresponding to the search information input by the user, and then determine the route from the location of the mobile terminal to the location of the commodity.

In an embodiment, according to the location of the mobile terminal 310, commodities within a predetermined range of the mobile terminal may be determined, and commodity information corresponding to the commodities may be sent to the mobile terminal, wherein the preset conditions It may be a product within a predetermined range of the location or a promotion within a predetermined range. For example, when the user walks into the supermarket, the user's location is determined according to the method described above, and then the promotion activities within 5 meters around the user are sent to the user's mobile terminal, or the user's location belongs to the category within the category. Promotions are sent to mobile terminals.

In addition, the server 320 may display the indoor location of the mobile terminal 310 to the user according to the stored indoor location distribution information and the location of the mobile terminal 310 .
