The payment method registration unit 101 provides information on the input payment method to a separate card server (not shown), and determines whether a payment method matching the information on the payment method exists from the card server (not shown). receive

When a payment method matching the information on the payment method exists, the payment method registration unit 101 registers the input payment method.

The purchase product list determining unit 102 determines a plurality of purchase items to be purchased by the user (S120).

The purchased product list determining unit 102 receives input of a plurality of purchase items to be purchased by the user from the user through an input interface device. For example, the purchase product list determining unit 102 may receive milk, cereal, rice, and the like from the user. In one embodiment, the purchase product list determining unit 102 may provide a user interface that provides a function for inputting purchase items to a user through an output interface device.

The purchased product list determining unit 102 provides the purchased items to the mart server 200 (S130).

The sales product providing unit 201 of the mart server 200 selects sales products corresponding to the purchase items using the received purchase items (S140).

In the database of the mart server 200, each purchased item and a plurality of sales products are matched and stored in advance. For example, when the purchase item is milk, milk and milk products sold at the mart may be matched and stored in the database.

The product for sale provider 201 selects a plurality of products for sale that match each of the purchased items from the database of the mart server 200 and transmits the selected products for sale to the smart cart 100 (S150).

The purchase product list determination unit 102 of the smart cart 100 generates a purchase product list using the received products for sale (S160).

The purchase product list determining unit 102 provides the received products for sale to the user through an output interface device. In one embodiment, the purchase product list determining unit 102 provides the user with sales products corresponding to each of the purchased items through an output interface device. For example, when the purchased items are milk and eggs, sales products corresponding to milk and sales products corresponding to eggs are provided to the user through the output interface device.

In addition, the purchased product list determination unit 102 receives a selection input for sales products corresponding to each of the purchased items from the user through an input interface device, and generates a purchased product list based on the received selection input. . For example, when the purchased items are milk and eggs, a selection input for at least one of sales products corresponding to milk and a selection input for at least one of sales products corresponding to eggs are received, and a list of purchased products is determined. The unit 102 may determine sales products corresponding to the received selection inputs as purchased products, and generate a purchased product list including the determined purchased products.

The purchased product list determining unit 102 provides the generated purchased product list to the mart server 200 (S170).

The movement route determining unit 102 of the mart server 200 determines the movement route using the received purchase product list (S210).

Figure 4 is a flow chart showing the specific process of step S210 of Figure 3.

The movement line determining unit 102 selects volume values corresponding to the purchased products included in the purchased product list from the database of the mart server 200 (S211).

In the database of the mart server 200, each purchased product and volume value are matched in advance and stored. For example, the volume values of milk product A and milk product A are pre-matched and stored in the database, and the volume values of egg product C and egg product C are pre-matched and stored in the database.

The movement line determining unit 102 determines whether the sum of the selected volume values is greater than a preset reference volume (S212).

In one embodiment, the preset reference volume may be determined based on the volume of an internal space in which the smart cart 100 accommodates products. For example, a volume of 60% of the internal space of the smart cart 100 may be set as a preset reference volume. However, it is not limited thereto.

If the sum of the selected volume values is greater than the reference volume, the flow path determining unit 102 classifies the purchased products by stacking level to create a plurality of purchased product groups (S213).

In the database of the mart server 200, each of the purchased products may be pre-matched and stored.

The stacking level may be determined using the degree of handling indicating the degree of damage of the product, the weight of the product, and the volume of the product. In the database of the mart server 200, each of the purchased products, the degree of handling, weight, and volume are pre-matched and stored.

In the database of the mart server 200, a plurality of pre-set score ranges and a plurality of stacking levels may be matched and stored. For example, 1 to 10 points match stacking level 5, 11 to 20 points match stacking level 4, 21 to 30 points match stacking level 3, 31 to 40 points match stacking level 2, and 41 points The above can be matched with stacking level 1.

The score of the purchased product is determined by the degree of handling, weight, and volume of the purchased product, and the stacking level matching the score range to which the determined score belongs is determined as the stacking level of the purchased product.

The score of the purchased product may be determined by Equation 1 below.

In Equation 1, P means a score, C means handling care, W means weight, and V means volume. In addition, K1 means the maximum value that can be set for handling caution, K2 means the maximum value that can be set for weight, and K3 means the maximum value that can be set for volume. In addition, J means a score correction factor.

In one embodiment, the score correction coefficient may be set to a starting value of the largest score section among a plurality of score sections. For example, when the score range corresponding to the stacking level 1 is 41 points or more, 41, which is the starting value of the score range, may be set as a score correction factor.

The movement line determining unit 102 selects a stacking level corresponding to each of the purchased products from the database of the mart server 200, and groups the purchased products having the same stacking level to create a plurality of purchased product groups. For example, if there are 10 purchased products with a stacking level of 1, 5 purchased products with a stacking level of 2, and 6 purchased products with a stacking level of 4, 10 purchased products with a stacking level of 1 A purchased product group including a purchased product group, a purchased product group including 5 purchased products having a stacking level of 2, and a purchased product group including 6 purchased products having a stacking level of 4 are created.

In addition, the movement route determining unit 102 creates movement routes corresponding to purchased product groups (S214).

The movement route determining unit 102 determines the movement routes of purchased product groups in descending order of stacking level.

In the database of the mart server 200, each of the purchased products and locations are matched and stored, and the movement route determining unit 102 determines the movement route corresponding to the purchased product group by using the locations of the purchased products included in the purchased product group. .

In one embodiment, spaces inside a mart are partitioned into a plurality of square spaces, and a square space including a place where a purchased product is displayed may be determined as a location of a purchased product. That is, each purchased product and a square space may be matched and stored in the database.

Also, in the database, each combination of randomly selected two of the purchased products is matched and stored with the number of square spaces connecting the arbitrary two. That is, the distance between each of the combinations of randomly selected two of the purchased products and the arbitrary two is matched and stored. For example, assuming that there are 5 purchased products, since the number of cases in which 2 of the purchased products are selected is 10, there is a gap between each of 10 combinations of randomly selected two of the purchased products and two random ones. The number of square spaces connecting is matched and stored in the database. That is, a combination of two arbitrary square spaces among the square spaces partitioning the mart and the number of square spaces connecting the two square spaces are matched and stored in the database.

In one embodiment, the number of square spaces connecting the two square spaces is set in consideration of a path through which the smart cart 100 can pass. For example, if the smart cart 100 actually needs to run even if it is a square space attached to each other, the number of square spaces required for the smart cart 100 to run will be set to the number of square spaces connecting the two square spaces. can

First, the movement line determining unit 102 determines the number of square spaces connecting each of the purchased products included in the purchased product group having the lowest stacking level (hereinafter referred to as the 'first purchased product group'), The purchased product with the smallest number of square spaces may determine the location as the starting point of the movement line.

In addition, the movement route determining unit 102 determines a plurality of preliminary movement lines that can be connected by penetrating both the position of the purchased product set as the starting point and the positions of the remaining purchased products included in the first purchased product group, and A distance required to connect all positions of purchased products included in the first purchased product group is determined for each of the purchased product groups. Also, the movement route determining unit 102 determines a combination having the smallest distance among the preliminary movement routes as the movement route. In one embodiment, the distance of the preliminary circulation may be determined by the total number of dead spaces included in the preliminary circulation. For example, when three purchased products are included in the first purchased product group, two preliminary lines that can connect the location of the purchased product as a starting point and the locations of the remaining two purchased products are calculated. The movement route determining unit 102 may determine the total number of square spaces required to connect the positions of the three purchased products as the distance of the preliminary movement route, and determine the distance for each of the two preliminary movement routes.

When the flow line corresponding to the first purchased product group having the lowest stacking level is determined, the flow line determining unit 102 determines the next higher stacked product group than the first purchased product group whose stacking level is determined (hereinafter referred to as 'second purchased product group'). (referred to as 'purchased product group') determines the flow path.

The movement line determining unit 102 determines the number of square spaces connecting between the final position of the previously determined movement line and each of the purchased products included in the second purchased product group for which the movement line is to be determined, and the number of square spaces is The smallest purchased product can determine the location as the starting point of the circulation.

In addition, the movement line determining unit 102 determines a plurality of preliminary movement lines that can be connected by penetrating both the position of the purchased product set as the starting point and the positions of the remaining purchased products included in the second purchased product group, and A distance required to connect all locations of purchased products included in the second purchased product group is determined for each of the purchased product groups. Also, the movement route determining unit 102 determines a combination having the smallest distance among the preliminary movement routes as the movement route. In one embodiment, the distance of the preliminary circulation may be determined by the total number of dead spaces included in the preliminary circulation. For example, when three purchased products are included in the second purchased product group, two preliminary lines that can connect the location of the purchased product as a starting point and the locations of the remaining two purchased products are calculated. The movement route determining unit 102 may determine the total number of square spaces required to connect the positions of the three purchased products as the distance of the preliminary movement route, and determine the distance for each of the two preliminary movement routes.

In addition, the movement line determination unit 102 provides the generated movement lines to the smart cart 100 (S215).

When the sum of the selected volume values is less than or equal to the reference volume, the movement route determining unit 102 generates a movement route corresponding to the purchased products (S216).

When the sum of the selected volume values is less than or equal to the reference volume, the movement route determining unit 102 does not create a purchased product group and creates one movement route that can connect the positions of all received purchased products with the shortest distance.

In addition, the movement line determining unit 102 provides the generated movement line to the smart cart 100 (S217).

Through this, the user may be provided with a suitable flow path for obtaining purchased products, and through this, the user's convenience may be improved. Furthermore, since the copper wires are provided in an order suitable for stacking, even when there are many products to be purchased, the user can smoothly stack the products in the cart. Through this, user convenience may be improved.

Referring back to FIG. 3 , the movement line providing unit 103 of the smart cart 100 provides the movement line received from the mart server 200 to the user through an output interface device (S230).

Through this, the user can easily move to the location of the purchased product by referring to the movement line without separately finding the location of the purchased product.

When one movement line is received where the sum of the selected volume values is equal to or smaller than the reference volume, the movement line providing unit 103 provides the received movement line to the user.

When a plurality of copper wires are received because the sum of the selected volume values is greater than the reference volume, the copper wire providing unit 103 provides the received copper wires in descending order of stacking level to the user.

5 is a flowchart illustrating a specific process of step S230 of FIG. 3 .

First, the copper wire providing unit 103 provides a copper wire having the lowest stacking level to the user (S231). For example, when a copper line corresponding to a purchased product group having a stacking level of 1 and a copper wire corresponding to a purchased product group having a stacking level of 3 are received, the copper wire providing unit 103 stores purchased products having a stacking level of 1 The movement line corresponding to is displayed to the user through the output interface device.

In addition, the movement line providing unit 103 determines whether the movement line is completed by using the location of the smart cart 100 (S232).

In one embodiment, the movement line provider 103 may determine that the movement line is completed when the distance between the location of the smart cart 100 and the position of the purchased product located at the end of the movement line is smaller than a preset reference distance. .

In one embodiment, the movement line providing unit 103 may receive a movement line termination input from a user through an input interface device. When a movement route end input is received, the movement route providing unit 103 may determine that the movement route being provided to the user is completed.

When the copper wire is completed, the copper wire providing unit 103 compares the stacking level of the completed copper wire with the maximum level (S233).

In one embodiment, the maximum level means the highest stacking level among stacking levels corresponding to copper wires. For example, when a copper wire corresponding to stacking level 1 and a copper wire corresponding to stacking level 3 are received, the maximum level is 3.

When the stacking level is the maximum level, the copper wire providing unit 103 ends the copper wire providing process.

If the stacking level is not the maximum level, the copper wire providing unit 103 outputs a copper wire next to the copper wire for which the stacking level is completed (S234).

Further, the copper wire providing unit 103 repeatedly performs steps S232, S233, and S234 until the stacking level of the completed copper wire becomes equal to the maximum level.

In an embodiment not shown, the purchased product registration unit 104 may determine a difference between the weight before the purchased product leaves the inner space and the weight after the purchased product leaves the inner space as the third weight. When the difference between the first weight and the third weight is within a preset error range, the purchased product registration unit 104 may exclude the registered product from the registered product list.

Referring back to FIG. 3 , when the distance between the location of the smart cart 100 and the location of the preset payment space is smaller than the preset reference distance, the purchased product register 104 allows the user to input the registration end signal. A user interface is provided to the user.

When the registration end signal is input from the user through the input interface device, the purchased product registration unit 104 calculates the sum of the first weights of the registered products included in the registered product list at the time when the registration end signal is input to the checkout terminal 300 ) is provided (S250).

The payment approval unit 301 of the checkout terminal 300 determines the sum of the fourth weight detected through the weight sensor included in the input interface device of the checkout terminal 300 and the first weights of registered products included in the registered product list. It is determined whether or not to proceed with payment using (S310).

In one embodiment, the input interface device of the checkout terminal 300 includes a weight sensor, and the weight sensor may be disposed on the payment space. When the smart cart 100 is positioned on the weight sensor of the checkout terminal 300, the weight sensor detects a fourth weight.

In addition, the payment approval unit 301 compares the sum of the received first weights and the weight of the smart cart 100 with the fourth weight, and compares the received sum of the first weights with the weight of the smart cart 100. When the difference between the added weight and the fourth weight is within the preset error range, a payment progress approval signal is provided to the smart cart 100 (S320).

When the payment progress approval signal is received, the payment unit 105 of the smart cart 100 performs payment for the registered products included in the registered product list using the payment method of the registered user (S330).

Through this, since payment proceeds immediately without waiting time for payment of registered products, user convenience is improved and congestion in the store can be reduced because users do not have to wait for payment.

When the payment is completed, the payment method registration unit 101 cancels the registration of the payment method of the registered user.

In addition, when the payment is completed, the payment unit 105 of the smart cart 100 provides the mart server 200 with a payment completion signal along with a registered product list. When the registered product list and the payment completion signal are received, the stock updating unit 203 of the mart server 200 updates the quantity of sale products stored in the database of the mart server 200 using the registered products included in the registered product list. do.
