For example, when the weight of one bottle of vinegar is 200g, and the weight of the area for placing vinegar on the shelf is reduced by 400g, the user takes 2 bottles of vinegar on the shelf. When the number of the commodities on the shelf changes, the second LiFi communication module on the shelf updates the number of the commodities on the shelf, and uploads commodity information such as the positions of the commodities, the types of the commodities, the change of the number and the like to the lighting device, so that the lighting device uploads the changed commodity information to the server, and the final commodity state updating is completed by the server. The server can be a computer host or a cloud server and the like, and is used for receiving information such as commodity types and corresponding commodity quantity changes on the goods shelf sent by the lighting device.

Referring to fig. 3, an embodiment of the invention provides a shopping guide method applied to a shopping cart, such as the shopping cart 100 in fig. 1 or fig. 2. As shown in fig. 3, the method comprises the steps of:

s31, establishing communication connection with the lighting device and the shelf through the first LiFi communication module;

in this embodiment, when the shopping cart main body approaches the shelf, the controller controls the first LiFi communication module to establish a communication connection with the plurality of lighting devices in the shopping place where the shelf is located, and sends the ID of the shopping cart to the plurality of lighting devices. And when the first LiFi communication module analyzes that the intensity of the LiFi downlink signal sent by the lighting device is smaller than a preset intensity threshold value, searching the strongest LiFi downlink signal again, wherein the lighting device to which the strongest LiFi signal belongs is the shopping area where the shopping cart is currently located. Since the correspondence between the lighting device ID and each shelf ID in the shopping area is established in advance. The controller can determine shelves in the current shopping area and communicate with a plurality of second LiFi communication modules on the shelves inside the current shopping area through the first LiFi communication module.

S32, receiving first commodity information of commodities changed on the shelf, which is sent by the shelf, through the first LiFi communication module;

in this embodiment, the commodity changed on the shelf may be a commodity newly added on the shelf, or may be a commodity leaving the shelf. The shelf also senses, via the second weighing cell, that the item is removed by the user or placed on the shelf by the user. Then, the second LiFi communication module may acquire first commodity information of the commodity taken away by the user. The third LiFi communication module of the lighting device instructs the second LiFi communication module to transmit the first commodity information of the commodity taken away by the user. The controller receives the first commodity information through the first LiFi communication module. The first commodity information comprises commodity identification, commodity quantity, positions and numbers of the shelves where the commodities are located, commodity states and other information of the commodities which are changed on the shelves, wherein the commodity states comprise leaving the shelves and placing the commodities on the shelves.

S33, receiving second commodity information of the corresponding changed commodities in the shopping cart main body, which is sent by the lighting device and collected by the image collection device, through the first LiFi communication module;

in this embodiment, in the process that a user selects and purchases goods from a shelf and places the goods in a shopping cart, an image acquisition device in a shopping area acquires motion images of the user and images of the goods placed in the shopping cart frame by frame at a high speed, and a server determines second goods information of the goods placed in the shopping cart according to the acquired images of the goods and sends the second goods information to a first LiFi communication module through a lighting device. The second commodity information comprises commodity identification, commodity quantity, positions and numbers of shelves where the commodities are located, states of the commodities and the like of the commodities which are changed in the shopping cart, wherein the states of the commodities comprise leaving the shopping cart and placing the commodities in the shopping cart. Different commodities correspond to different commodity identifications, and the commodity identifications can be digital codes or bar codes and the like.

In some embodiments, if the product information of the product decreased on the shelf coincides with the product information of the product increased in the shopping cart, the product information of the product put in the shopping cart main body is added to the original product information. If the commodity information of the commodity added to the shelf matches the commodity information of the commodity reduced from the shopping cart, the commodity information of the commodity put in the shopping cart body is deleted from the original commodity information. For example, if the commodity information of the commodity decreased on the shelf is consistent with the commodity information of the commodity increased in the shopping cart, the price of the commodity increased in the shopping cart is calculated in the total price of the commodity to be purchased; if the information of the newly added item on the shelf coincides with the item information of the item reduced in the shopping cart, the price of the item reduced in the shopping cart is subtracted from the total price of the items to be purchased.

In some embodiments, the lighting device may indicate that the tag lamp corresponding to the commodity on the shelf flashes, the first LiFi communication module searches for a signal of the flashing tag lamp, decodes the commodity identifier from the signal transmitted by the tag lamp, and if the commodity identifier unlocked from the signal transmitted by the tag lamp of the shopping cart is consistent with the commodity identifier parsed from the image captured by the image capturing device, the first LiFi communication module further parses other commodity information except the commodity identifier from the signal transmitted by the tag lamp, for example: the information of the unit price, the quantity, the production place, the production merchant, the production date, the quality guarantee period, the use method and the like of the commodity is displayed and sent to the display device, so that the display device displays the information. The controller of the shopping cart may also aggregate and display via the display a list, price and details of the items purchased in the shopping cart.

If the customer cancels the purchase of the item, the user needs to return the item in the cart to the shelf on which the item is placed. The customer needs to enter a shopping area where a goods shelf for placing the goods is located first, the goods are placed on the goods shelf, a lighting device in the shopping area obtains second goods identification information of the goods sent by a label lamp, when the second goods identification information obtained by an image acquisition device is matched with the first goods identification information, a server updates warehousing information and instructs the lighting device to send purchased goods updating information to a shopping cart, a LiFi module of the shopping cart receives the updated information, the updated information comprises updated goods types, goods names, prices, quantities, total payment price and the like, and the LiFi module sends the total payment price to a display device so that the display device can display the total payment price.

In some embodiments, when the returned item is not placed on the correct shelf, then the first item identification information and the second item identification information are not consistent. At this point, the controller will not update the information for the items purchased in the shopping cart. Only when the goods are placed in the correct position will the shopping cart update the price. That is, when the returned goods are not placed at the correct position on the shelf, the total payment price displayed on the display device before and after the goods are returned does not change to prevent the customer from randomly placing the goods during the process of returning the goods, thereby saving the maintenance cost of the shopping place.

In some embodiments, the above method further comprises the steps of:

s35, acquiring the identity information of the user through an identity identification module;

s36, determining the payment information bound with the identity information;

s37, sending the identity information and the payment information to a lighting device through the first LiFi communication module, so that the lighting device sends the identity information and the payment information to a server;

and S38, if the server determines that the identity information and the payment information are legal, issuing a payment command to enable the user to pay according to the payment command.

In this embodiment, the user inputs the identity information through the information acquisition module, for example: face image, fingerprint, or shopping ID. The method comprises the steps that information is extracted by a Lifi signal module of the shopping cart, identity information and payment information bound with the identity information are uploaded to a lighting device of a shopping area where the information is located, the lighting device in the current shopping area reports the identity information and the payment information to a server, and the server sends a connection success message after confirming the validity of the identity and the bound payment information so that an information acquisition module of the shopping cart sends a shopping or payment command. Further, the above-mentioned payment order is issued by oneself in the long-range of accessible cell-phone APP, and cell-phone APP converts wireless signal into the liFi light signal through WIFI bluetooth conversion liFi signal unit to accomplish information transmission and receipt by the liFi signal unit of shopping cart.

In some embodiments, the above method further comprises the steps of:

s39, receiving payment confirmation operation of the user;

s40, sending the information of the commodity placed in the shopping cart main body and the payment information to a server according to the payment confirmation operation so as to enable the server to complete payment;
