FIG. 2 is a diagram illustrating an automatic calculation function according to an embodiment of the present invention. FIG. 3 is a view showing a cart computation housing module provided in a cart according to an embodiment of the present invention. FIG. 4 is a view illustrating a cart computation housing module according to an embodiment of the present invention. It is a picture showing the figure.

The cart device of the present invention may include a cart 1, a cart computation housing module 10, a cart RF antenna 120, a purchase amount calculating section 130, and a control section 110. In addition, a display unit 140 and a cash register database 150 are included.

The cart 1 may be a cart 1 or the like used in a mart for carrying and carrying articles. The cart can be moved by attaching a wheel to the cart 1, so that the customer can move the cart 1 while dragging the cart 1 and load necessary articles on the cart 1.

The cart calculation housing module 10 may be a housing coupled to the cart 1 and provided with a cart RF antenna 120, a purchase amount calculation unit 130, and a control unit 110. The cart calculation housing module 10 may be provided near the handle of the cart 1 and may be attached to various positions such as the side, front, and bottom surfaces of the cart 1. Although the cart calculation housing module 10 has been described as having a housing shape of a rectangular parallelepiped, it is not limited thereto and may have various shapes such as a cylindrical shape and a hexagonal column shape.

The cart RF antenna 120 wirelessly receives article information and price information as an RF tag chip of the article loaded on the cart 1 and wirelessly transmits the article information and price information to the cash register RF antenna 120. [ The cart RF antenna 120 is implemented so as to have a communication coverage capable of communicating with an RF tag chip of an article to be loaded on the cart 1 so that whenever the cart 1 is loaded with the article, And wirelessly communicates with the RF tag chip.

 Each of the articles sold in the market is provided with an RF tag chip, and the article information and price information of the article are stored in the RF tag chip. Therefore, when the cart 1 contains an article, the cart RF antenna 120 activates the RF tag chip attached to the article to be received in the cart 1, and receives the article information and the price information from the RF tag chip.

The purchase amount calculation unit 130 calculates an amount of purchase (hereinafter, referred to as 'RF read purchase amount') obtained by summing up the price information received from the RF tag chip of the articles loaded on the cart 1. For example, assuming that the first, second and third articles are loaded on the cart 1, a price of 10,000 won, which is the price of the first article, is received from the RF tag chip attached to the first article, It is assumed that a price of 40,000 won for the second article is received from the RF tag chip and 25,000 won for the price of the third article from the RF tag chip attached to the third article. The total price of 1,2,3 items is 75,000 KRW, which is equivalent to the RF read purchase price.

The control unit 110 radiates the article information wirelessly received through the cart RF antenna 120 and the RF readout purchase amount calculated by the purchase price calculation unit through the cart RF antenna 120, Lt; / RTI > For example, when the cart 1 loaded with the first, second, and third articles passes through the cash register 20, the cart RF antenna 120 provided in the cart 1 moves to the first, second, And transmits the RF readout purchase amount, which is the total price of the first, second, and third articles, to the cashier RF antenna 120 in the cash register 20.

Accordingly, the article information and the RF readout purchase amount received from the cash register RF antenna 120 are provided to the POS terminal 210, and the payment for the purchase amount is made by the customer. Therefore, in the past, the cache has to scan the barcode of the article through the barcode reader when the user has passed through the counter. However, the present invention can be quickly calculated without any additional barcode scan. Therefore, the waiting line of the counter can be greatly reduced.

On the other hand, in the cart calculation housing module 10, the display unit 140 displaying the article information of the articles, the price information of each article, and the RF read purchase amount stored in the cart 1 may be displayed. The display unit 140 may be implemented in a single form of a touch screen panel on which input can be performed. The touch screen panel is a display window that provides a touch screen screen capable of simultaneously performing input and display, and displays a graphical user interface (GUI) for communication with a customer.

On the other hand, depending on the characteristics of the mart, the counter for payment may be different for each item sold. For example, a first counter for professionally calculating only a small amount of cosmetics, a second counter for professionally calculating expensive goods of jewelry, and a third to fifth counter for calculating only general goods can be assigned . Therefore, it is necessary for the customer to guide the customer to a dedicated checkout counter at which the items stored in the cart 1 can be calculated.

To this end, the cart calculation housing module 10 is assigned with a cash register database 150 in which cash register information is allocated for each article information. For example, the first to tenth articles, which are cosmetics, are allotted and stored as the register information of the register, the eleventh article to the twentieth article of the jewelry are stored as the register information of the second register, Items 31 to 40, which are the products, can be stored in the third to fifth counters as the counter registration information.

The cash register database 150 may be a hard disk drive, a solid state drive (SSD), a flash memory, a compact flash card, an SD card (Secure Digital Card) , An SM card (Smart Media Card), an MMC card (Multi-Media Card), or a memory stick, which may be provided in the device or may be provided in a separate device have.

The cart RF antenna 120 also receives the counter identification information from the counter RF antenna 120. For example, when the cart 1 enters the first checkout slot, the POS terminal 210 of the first checkout counter receives the counter identification information indicating the first checkout slot via the checkout RF antenna 120, (120) to the cart RF antenna (120).

The control unit 110 extracts from the cash register database 150 the cash register registration information allocated to the article information received through the cart RF antenna 120. When the cash register registration information extracted from the cash register database 150 is received by the cash register RF antenna 120 The RF reading purchase amount is radiated through the cart RF antenna 120 and wirelessly transmitted to the cashier RF antenna 120 provided at the cashier.

For example, as shown in Fig. 4 (a), when the cart 1 on which the first article is mounted enters the first checkout, the checkout RF antenna 120 provided in the first checkout is configured to identify the first checkout counter And transmits the information to the cart RF antenna 120 wirelessly. The control unit 110 of the cart extracts the first checkout table as the checkout registration information allocated to the first product and accordingly the extracted checkout registration information and the checkout station identification information received from the checkout RF antenna 120 are identical to the first checkout The RF reading purchase amount is radiated through the cart RF antenna 120 and wirelessly transmitted to the checkout RF antenna 120 provided at the first checkout counter.

On the other hand, as shown in Fig. 4 (b), when the cart 1 on which the eleventh article is mounted enters the first checkout table, the checkout RF antenna 120 provided in the first checkout table is provided with identification information To the cart RF antenna (120). The control unit 110 extracts the second counter as the counter unit registration information allocated to the eleventh article. The control unit 110 then extracts the second counter from the second counter and the first counter, which is the counter identification information received from the counter RF antenna 120, The RF read purchase amount is not transmitted to the checkout RF antenna 120 wirelessly.

Further, when the extracted counter registration information does not match the counter identification information received from the counter RF antenna 120, the control unit 110 transmits the counter registration information counter registration information extracted from the checkout database 150 to the display unit 140 And the payment is made at the counter having the counter registration information. For example, when the cart 1 on which the eleventh article is mounted enters the first checkout, the first checkout, which is the checkout identification information received from the second checkout counter and the checkout RF antenna 120, It is displayed on the display unit 140 that the counter to which the eleventh article can be calculated is the second counter so as to move to the second counter and guide the user to perform the settlement.

On the other hand, there may be articles that are not sold with RF tag chips on the market. In this case, the article information and the price information can not be received. In consideration of this, the cart device of the present invention further includes means for reading an identification code (bar code or QR code) printed on the article. 5 to 6 will be described in detail below.

FIG. 5 is a block diagram of a cart device according to an embodiment of the present invention. FIG. 6 is a diagram illustrating a warning message generating condition according to the total weight of an article according to an embodiment of the present invention.

The cart device of the present invention is characterized in that the cart device 1 further includes identification code information 150 in addition to the cart 1, the cart calculation housing module 10, the RF antenna, the purchase price calculation unit 130, the control unit 110, the display unit 140, A database 180, an identification code reader 160, and a weight detection sensor 170. [

The identification code information database 180 is a database (DB) in which article information and price information are allocated for each identification code. The identification code may be a bar code or a QR code, and an identification code unique to each article is printed or attached. In the identification code information database 180, the article information and the price information of the article to which the identification code is attached are assigned and stored for each identification code.

The identification code reader 160 reads one of the bar code and QR code attached to the article. The identification code reader 160 can read the identification code attached to the article by scanning the identification code reader 160 with the identification code printed on the article before the customer loads the article into the cart 1. [

The purchase amount calculation unit 130 extracts the article information and the price information allocated to the identification code read through the identification code reader 160 and adds the purchase amount (hereinafter, referred to as 'barcode reading purchase amount'), which is the sum of the extracted price information, . Then, the total amount (hereinafter referred to as "total purchase amount") of the barcode reading purchase amount thus calculated is added to the total RF reading purchase amount. For example, if the RF tag chip is attached to the first article and the second article to be loaded on the cart 1, and only the identification code is printed on the third article and the fourth article without the RF tag chip, And the RF readout purchase price of 25,000 won, which is calculated by using the RF tag chip of the second article, and the readout barcode reading amount of 70,000 won, which is calculated by using the identification code of the third and fourth articles, corresponds to the purchase amount do.

Accordingly, the controller 110 transmits the article information wirelessly received through the cart RF antenna 120, the article information read through the identification code reader 160, and the purchase total calculated by the purchase price calculator to the cart RF antenna 120, And can be wirelessly transmitted to the counter RF antenna 120 provided at the counter. Therefore, even for the article printed with the identification code printed with no RF tag chip, the calculation is automatically performed in the cart 1, and payment can be made quickly.

On the other hand, in the case of stores that sell small items such as cosmetics stores and jewelery stores rather than large-scale marts, theft frequently occurs. In order to prevent such theft, the cart device of the present invention senses the weight of the article mounted on the cart 1 and induces correct settlement.

To this end, the cart device includes a weight detecting sensor 170 provided on the loading surface of the cart 1 on which the articles are loaded, and sensing the sensing weight, which is the total weight of the articles placed on the loading surface. The weight detection sensor 170 is implemented in the form of a plate plate and is provided on the loading surface of the article, which is the sea surface of the cart 1, so that the weight of the articles loaded on the cart 1 can be sensed to detect the sensing weight.

Further, the cart calculation housing module 10 has an article weight database in which weights are allocated and stored for each article information.

Therefore, the control unit 110 extracts the weight of the article information wirelessly received via the cart RF antenna 120 from the article weight database, and when the total weight of the articles, which is the sum of the weight of the extracted article information, If the range is out of range, a warning message is wirelessly transmitted to the cashier RF antenna 120 through the cart RF antenna 120.

For example, in the case where the weight of the first article is 200 g, the weight of the second article is 350 g, and the weight of the third article is 450 g, 1, 2 and 3 When the articles are loaded, the total weight of the articles obtained by summing the weights of the first, second and third articles extracted from the article weight database is 200 g + 350 g + 450 g = 1,000 g.

Assuming that the detection weight detected by the cart 1 sensor provided on the loading surface of the cart 1 on which the article is loaded is 1,200 g, assuming that the error range is 10%, the error range is 900 g to 1,100 g Therefore, the detection weight of 1,200 g is out of the tolerance range. The controller 110 wirelessly transmits a warning message to the cashier RF antenna 120 via the cart RF antenna 120 because it means that the goods are further contained in the cart 1, . Accordingly, the force terminal 210 of the cash register displays such a warning message, and the cashier confirms the article of the cart 1. [

When the total weight of the articles, which is obtained by summing the weight of the extracted article information, is out of the error range when compared with the sensed weight, the controller 110 notifies the display unit 140 of an error in loading the articles loaded on the cart 1, Lt; / RTI > Accordingly, if the customer confirms the confirmation through the display unit 140, the customer can confirm whether or not the goods are unloaded before entering the counter.

The embodiments of the present invention described above are selected and presented in order to facilitate the understanding of those skilled in the art from a variety of possible examples. The technical idea of the present invention is not necessarily limited to or limited to these embodiments Various changes, modifications, and other equivalent embodiments are possible without departing from the spirit of the present invention.
