The purchase amount calculator 171 calculates the total payment amount of the product according to the type of the product and the number of the goods withdrawn by the user is recognized the purchase request of the product.

The exchange amount calculating unit 172 recognizes that the exchange button is pressed, and calculates the total payment amount of the current product calculated according to the type of the product withdrawn and withdrawn for the exchange and the number of the product.

The amount exceeding notification unit 173 determines a prepayment amount when the total purchase amount of the product calculated according to the type of the product and the number of the goods withdrawn by the user is recognized because the purchase request of the product is recognized. The total payment amount of the current product, calculated according to the type of the product withdrawal and withdrawal for the exchange and the number of the product, by the recognition of the press of the exchange button, exceeding the previous total payment made with the card. Provides notifications when The notification may provide a notification to the user that the payment amount has been exceeded, and thus, the predetermined prepayment amount is additionally paid through the prepayment processor 131 of the payment management unit 130.

The refund amount calculator 174 recognizes that the refund button is pressed, and calculates the total payment amount of the current product calculated according to the type of the product and the number of the goods received by the user for the refund.

7 is a flow chart for explaining the procedure of the merchandise sales management method of the multi-vending machine according to the present invention.

Purchase process

Referring to FIG. 7, the merchandise sales management method of the multi vending machine according to the present invention uses the merchandise sales management device of the multi vending machine described above, and a redundant description thereof will be omitted.

First, the coordinate information, weight information and price information of the goods stored in the shelf in the multi-vending machine is managed (S100).

In step S100, coordinate recognition is performed on the areas of the shelves in which the goods are stored, and the product coordinate information is set based on the coordinates, and the product weight information and the product price information of the goods arranged in the areas of the shelves are provided. Can be set.

Next, it is recognized whether the payment card is inserted into the payment card insertion slot provided in the outside of the multi vending machine (S110).

In step S110, if the user does not recognize the pressing of the selection buttons provided on the outside of the multi-vending machine, and if the insertion of the payment card is recognized, the user recognizes the purchase request of the product.

Next, when the insertion of the payment card is recognized, the prepayment is approved for the preset amount (S120).

Step S120 provides a notification of the purchase price to the user based on the approved prepayment amount (S310).

Next, if the pre-payment amount is approved, the door lock of the multi vending machine is controlled to open the door of the multi vending machine (S130).

In step S130, when the prepayment amount is approved, the door of the multi vending machine is opened, and when the prepayment amount is not approved, the door locking device of the multi vending machine may be controlled so that the door of the multi vending machine is not opened.

Next, when the door of the multi-vending machine is opened, it recognizes the coordinates of the shelves in the multi-vending machine and grasps the type of goods drawn by the user based on the preset product coordinate information for each shelf (S140).

Next, by measuring the weight of the goods to be withdrawn or withdrawn from the shelf in the multi-vending machine to determine the number of goods based on the preset product weight information for each shelf (S150).

That is, the steps S140 and S150 determine the types of goods by grasping the shelf position of the goods withdrawn and withdrawn by the user by using a coordinate measuring sensor and a motion detection sensor, and the like by using a weight sensor provided for each shelf. Can count the number.

Next, the total payment amount of the product according to the kind of the product and the number of the goods withdrawn by the user is calculated (S160).

Next, when the total payment amount of the product selected by the user in the multi-vending machine is calculated and the door of the multi-vending machine is recognized by the user, the final payment processing is performed by reflecting the approved pre-payment amount (S170). .

8 is a flowchart illustrating a process of managing coordinate information, weight information, and price information of a product stored in a shelf in a multi-vending machine in the product sales management method of the multi-vending machine according to the present invention.

Referring to FIG. 8, a process of managing coordinate information, weight information, and price information of a product stored in a shelf in a multi-vending machine according to an embodiment of the present invention may include: first, an area of shelves provided vertically and horizontally in the multi-vending machine. Recognize the x, y coordinate with respect to (S200).

Next, the types of goods arranged for each area of the shelves are classified, and the product coordinate information is set for the goods arranged in the areas of the shelves based on the coordinate recognition values of the corresponding shelves (S210).

Next, the weights of the goods arranged for each area of the shelves are classified, and product weight information is set for the goods arranged in the areas of the shelves (S220).

Next, commodity price information is set for commodities arranged for each area of the shelves (S230).

FIG. 9 is a flowchart illustrating a process in which a user exchanges a product when a press of an exchange button is recognized in a product sales management method of a multi-vending machine according to the present invention.

Exchange process

Referring to FIG. 10, the process of exchanging goods by recognizing the press of the exchange button according to the present invention is first performed by the user when the press of the exchange button provided on the outside of the multi vending machine is recognized. Provides a notification requesting the payment card insertion (S300).

Next, the pressing of the exchange button is recognized, and the user compares the weight of the goods withdrawn or withdrawn for exchange with preset product weight information for each shelf (S310).

Next, if an error in the weight of the product does not occur, the total payment amount of the current product calculated according to the type of the product withdrawal and withdrawal for the exchange and the number of the product is calculated (S320).

Next, track your recent payment history and compare the total amount of your previous payment with the total amount of your current product, calculated by the type of product you've withdrawn and withdrawn for the exchange, and the number of products, In response to the exchange payment processing is performed (S330).

Step S330 compares the total payment amount of the previous product with the total payment amount of the current product, and when the amount to be paid additionally occurs (when the price of the incoming product to be exchanged is higher than the price of the withdrawn product), the corresponding card amount is increased. , And the total amount of the current product compared to the total amount of the current product, if the amount that needs to be refunded is generated (when the price of the incoming product to be exchanged is lower than the price of the withdrawn product), the previous total payment is cancelled. After the request, exchange payment processing can be performed with the total payment amount of the current product.

10 is a flowchart illustrating a process in which a user refunds a product by recognizing pressing of a refund button in a product sales management method of a multi-vending machine according to the present invention.
