Understanding the Shopping Mall and Supermarket IoT Solution - Smart Shopping Guide

Understanding the Shopping Mall and Supermarket IoT Solution - Smart Shopping Guide

The smart shopping guide solution applies to the following sub-scenarios in shopping malls:
  • When tablet kiosks are installed, the tablet kiosks display commodity information to customers, and Big Data statistics can be collected on customers' actions of picking up commodities. In this sub-scenario, BLE labels must be bound to commodities and tablet kiosks must be installed on shelves.
  • When no tablet kiosk is installed, Big Data statistics can be collected only on customers' actions of picking up commodities. In this sub-scenario, BLE labels must be bound to commodities.
The following describes how the smart shopping guide solution is implemented in these sub-scenarios.

Tablet Kiosks Are Installed

Figure 28-2 shows a scenario with tablet kiosks installed. Tablet kiosks connect to APs through Wi-Fi and to the smart shopping guide server through the Ethernet, and receive information from BLE labels through Bluetooth.

The solution is implemented as follows:

  1. A BLE label is bound to a commodity. The mobile app is used to associate the BLE label with the commodity and synchronize the association information to the smart shopping guide server.

    To associate a BLE label with a commodity, use the mobile phone camera to scan the commodity barcode and the Bluetooth function of the mobile phone to receive BLE label information.

  2. When a customer picks up the commodity, the BLE label bound to the commodity detects that the commodity is picked up by sensing the gravity change. The BLE label then sends a BLE broadcast packet carrying the BLE label ID to the tablet kiosk.

  3. After receiving the BLE broadcast packet, the tablet kiosk displays the commodity information mapping the BLE label ID if its camera sees a person in front. At the same time, the tablet kiosk sends the BLE label information to the smart shopping guide server through Wi-Fi.
    • The BLE broadcast packet sent by the BLE label may be received by multiple tablet kiosks. If the camera of a tablet kiosk sees a person in front of itself, the tablet kiosk displays commodity information; otherwise, it does not display commodity information.
    • The tablet kiosk has an app installed locally, and the app must have the smart shopping guide server information configured and can cache information. If the tablet kiosk has cached commodity information be displayed and the smart shopping guide server verifies that the commodity information will not be updated, the commodity information is displayed. If no commodity information is cached on the tablet kiosk or the shopping guide server verifies that the commodity information needs to be updated, new commodity information will be downloaded from the tablet kiosk and then displayed.
    • If a customer picks up multiple commodities concurrently, the app of the tablet kiosk will provide a display sequence for the customer to select a commodity whose information is to be displayed. For example, a customer picks up commodities A and B concurrently and information about commodity A is displayed currently, the customer can select commodity B. The tablet kiosk will then display information about commodity B.
  4. The smart shopping guide server performs Big Data analytics on the data sent by the BLE label, and provides a visualized analysis result as reference for the shopping mall to make timely and accurate marketing strategies.

No Tablet Kiosk Is Installed

As shown in Figure 28-3, when no tablet kiosk is installed, BLE labels connect APs' Bluetooth modules by sending BLE signals and to the smart shopping guide server through the Ethernet.

Figure 28-3  Network when no tablet kiosk is installed

The solution is implemented as follows:

  1. A BLE label is bound to a commodity. The mobile app is used to associate the BLE label with the commodity and synchronize the association information to the smart shopping guide server.

    To associate a BLE label with a commodity, use the mobile phone camera to scan the commodity barcode and the Bluetooth function of the mobile phone to receive BLE label information.

  2. When a customer picks up the commodity, the BLE label bound to the commodity detects that the commodity is picked up by sensing the gravity change. The BLE label then sends a BLE broadcast packet carrying the BLE label ID to the tablet kiosk.

  3. The AP's Bluetooth module transmits BLE data transparently. After receiving a BLE broadcast packet, the AP sends the packet to the smart shopping guide server based on the IP address and port number of the host computer specified on the AP.

  4. The smart shopping guide server performs Big Data analytics on the data sent by the BLE label, and provides a visualized analysis result as reference for the shopping mall to make timely and accurate marketing strategies.

NOTE:

The smart shopping guide server functions as the host computer of APs. Therefore, the host computer in the following sections refers to the smart shopping guide server.
