Description

TECHNICAL FIELD [0001] The present invention relates to a system and a method for purchasing goods using a mobile smart cart,

The present invention relates to a system and method for purchasing goods, and more particularly, to a system and method for purchasing goods using a plurality of barcode recognition units in a mobile smart cart, It is not necessary to spend time for calculation and settlement in the store by paying through the intervention between the store server and the settlement server through the wireless communication network with respect to the commodities for which the calculated commodity is received from the store server through the store server, To a system for purchasing goods using a mobile smart cart, and a method thereof, which can reduce costs.

Generally, a large merchandise store or a shopping center recognizes a merchandise using a barcode reader at the time of payment of a merchandise and performs payment for the merchandise. When a customer wants to purchase a product at a large commodity store or a shopping center, the customer uses a commodity receiving and moving means such as a basket or a shopping cart to purchase the purchased commodity. Then, the customer places the goods to be purchased in the goods receiving and moving means, selects the goods, and moves to the checkout counter. Thereafter, the user can directly obtain the purchased goods, calculate the value by listing the products purchased at the counter, or store the goods to the shop through a POS (Point of Sale) terminal equipped at the counter or the like The barcode information for classifying the name of the goods and the goods value is read as data, and the barcode information is calculated again to complete the calculation of the goods. Then, the user moves the calculated commodity to the vehicle, and loads the commodity to the place where the commodity is consumed.

For this reason, all customers are dragging their shopping carts and shopping, which makes the store very crowded and inconveniences other customers. There was a problem that the customer had to take out the purchased product from the shopping cart one by one to make the calculation at the counter and put it back into the shopping cart after the calculation.

In addition, the store employee has to calculate the bar code attached to the merchandise at the checkout counter every time, so that it takes a long calculation time. Because of this, the time for customers to stand in line at the checkout counter for calculation is lengthened, and the complaints of customers have increased day by day due to the complexity around the checkout counter.

To solve these problems, even if we increased the number of cashiers and cashiers, we had to read the bar codes of the products one by one and calculate them. Moreover, if the number of cashiers increases, the labor cost of the cashier is added to the price of the commodity, and the consumer purchases the commodity at a higher price.

As an alternative to this, a commodity payment technology using a conventional barcode reader has emerged.

1 is a configuration diagram of a conventional shopping cart having a bar code reader.

As shown in FIG. 1, the conventional shopping cart 100 includes a barcode reader 110.

After selecting a product in a large store, the customer enters barcode information of the product into the barcode reader 110 of the shopping cart 100, purchases the product, and places the product in the shopping cart 100 to settle the purchase product. In addition, when the customer cancels the purchase of the selected product, when the customer recognizes the barcode information of the product to be canceled while holding the cancel button attached to the barcode reader 110, the customer cancels the corresponding purchase product from the entire purchased product list You can pay for purchases you have purchased so far.

The conventional technology in which the barcode reader 110 is mounted on the shopping cart 100 and recognizes the goods is a method which is based solely on the conscience of the customer. It is an object of the present invention to provide a barcode reader / I could not find the case properly and could not use it realistically. To replace this, a system has been considered in which the function of the balance is added to the shopping cart 100 to recognize the total weight as an error if the error of the weight is out of tolerance. However, when the customer recognizes the barcode with a low- Such systems could not prevent theft if they were replaced.

In order to solve these technical problems, RFID (Radio-Frequency IDentification) technology has emerged as a next generation leader of logistics systems. However, there is a recognition error and a price of RFID chip when technically passing a large number of articles through a reader in an instant The bar code recognition technology used for decades at a high price could not be replaced in an instant.

On the other hand, a bar code recognition technology is generally referred to as code, in which a predetermined object is displayed in English, numerals, or special symbols. However, remembering the code and typing it into your computer is very cumbersome and difficult. In particular, it is almost impossible to handle all kinds of items, such as household goods, with separate codes. In order to solve such a problem, a bar code reader is used as a barcode reader which optically combines bar codes having different thicknesses in place of common codes and codes the bar codes. (110). The bar code reader 110 refers to an input device for reading electronic signals generated by irradiating light onto a printed bar code and depending on the intensity of reflected light.

The barcode reader 110 generates an electronic signal according to the intensity of light reflected by applying light to an input medium on which a barcode is printed, and uses an optical principle that converts a logic circuit into an internal code of a computer by operating a logic circuit. When a customer buys a commodity at a supermarket, the customer can often see a scene where the barcode reader 110 reads the barcode printed on the commodity and makes it into sale data. The barcode reader 110 is widely used from the production management to the sales management since the data input is accurate and easy to use. Especially, it is evaluated as a revolution in the distribution field.

However, although the bar code reader 110 is commonly used in a large-sized shopping mall near us, there is still a problem that a person has to check every bar code recognition and a customer has to line up for a long time on many weekends.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The configuration of the present invention and the operation and effect thereof will be clearly understood through the following detailed description. Before describing the present invention in detail, the same components are denoted by the same reference symbols as possible even if they are displayed on different drawings. In the case where it is judged that the gist of the present invention may be blurred to a known configuration, do.

2 is a block diagram of a system for purchasing goods using a mobile smart cart according to an embodiment of the present invention.

2, the merchandise purchasing system 200 according to the present invention includes a mobile smart cart 210, a store server 220, and a merchandise payment server 230.

Hereinafter, each of the components of the product purchase system 200 according to the present invention will be described. The components of the mobile smart cart 210 will be described later in detail with reference to FIG. Here, the store server 220 can communicate with a plurality of mobile smart carts 210 via a wireless communication network.

The mobile smart cart 210 recognizes a barcode of a product in real time by emitting a plurality of optical signals as a product is inserted into a certain position in the cart by a user, and stores product information matched with the recognized barcode and payment To the store server 220 through the wireless communication network and receives a response. That is, when the user inserts the product into the mobile smart cart 210, the mobile smart cart 210 recognizes the product through the optical signals for barcode recognition installed on each side of the cart, and matches the corresponding barcode through the wireless communication network And displays the price of the product to the user in real time. The mobile smart cart 210 receives merchandise information (e.g., type of merchandise, price of the corresponding time, related merchandise information, event information, etc.) matching the barcode with the store server 220 through the wireless communication network.

After the user recognizes all the goods to be purchased by the mobile smart cart 210 and ends the calculation, the mobile smart cart 210 requests payment through the wireless communication network for the goods that have been calculated so far according to the payment request of the user, Upon receipt of the payment completion signal, the merchandise purchase is completed. In addition, the user can connect to a wireless communication network through a portable terminal (e.g., a cellular phone) possessed by the user, and proceed with settlement of goods according to interlocking between the portable terminal and the mobile smart cart 210. [ Here, the user does not have to line up for a long time for calculation and settlement in the shopping mart by paying the goods through the mobile settlement through interlocking between the mobile smart cart 210, the store server 220 and the goods settlement server 230 . In addition, Mart can save money by reducing the number of cashiers.

After the settlement is completed, the mobile smart cart 210 passes through a specially designed cart passage at the store. At this time, only the mobile smart cart 210 receiving the settlement completion signal from the store server 220 of the large-sized mart can pass. Otherwise, the store server 220 does not pass the mobile smart cart 210 that has not been paid. This prevents product theft.

The store server 220 informs the mobile smart cart 210 of the goods information requested from the mobile smart cart 210 and transmits the payment for the requested goods from the mobile smart cart 210 to the goods payment server 230 And informs the mobile smart cart 210 of the payment completion information that has been processed. That is, the store server 220 communicates with the mobile smart cart 210 via the wireless communication network and transmits the requested product information to the mobile smart cart 210 in the mobile smart cart 210. In addition, the store server 220 stores the calculated merchandise information for each mobile smart cart 210. Thereafter, when the calculation completion confirmation request is transmitted from the product payment server 230, the store server 220 confirms whether the calculated product information matches the stored product information so far, and returns the confirmation to the goods payment server 230 . When the store server 220 is informed of completion of settlement from the goods settlement server 230, the store server 220 transmits a settlement completion signal to the mobile smart cart 210 to complete the purchase activity.

The goods settlement server 230 performs payment processing for the goods transmitted from the store server 220 and notifies the store server 220 of the settlement completion information. When the merchandise settlement server 230 receives a payment request from the store server 220, the merchandise settlement server 230 requests the store server 220 whether the corresponding mobile smart cart 210 matches the merchandise information that has been calculated so far. When the merchandise settlement server 230 confirms the match from the store server 220, the merchandise settlement server 230 completes settlement remotely and informs the store server 220 of the settlement completion information. That is, the commodity settlement server 230 interlocks with the store server 220 to support settlement remotely. Here, the goods payment server 230 may be a mobile card payment server for a mobile card owned by the user. In this case, the mobile card payment server can work in cooperation with the store server 220 and the goods payment server 230 of the large-sized mart.

3 is a configuration diagram of an embodiment of the mobile smart cart of FIG. 2 according to the present invention.

3, the mobile smart cart 210 includes a barcode recognition unit 310, a wireless communication unit 320, a user interface unit 330, and a power supply unit 340. Here, the barcode recognition unit 310 includes a plurality of radiation units 311 and a plurality of reception units 312. The power supply unit 340 applies power to the barcode recognition unit 310, the wireless communication unit 320, and the user interface unit 330 so that the mobile smart cart 210 can be driven.

Each of the components of the mobile smart cart 210 will be described in detail as follows.

The barcode recognition unit 310 may be a barcode recognition unit that inputs all positions (e.g., an arbitrary region or an arbitrary angle) in the cart using a pilot transmission function, a diversity function, an error correction function, And recognizes the barcode of the product. For this purpose, the barcode recognition unit 310 includes a plurality of radiation units 311 and a plurality of reception units 312.

The radiation unit 311 and the receiving unit 312 may be installed on a plurality of surfaces of the mobile smart cart 210 so that the product can be placed in any position in the mobile smart cart 210. [ The barcode is recognized. That is, the radiating unit 311 and the receiving unit 312 use a pilot transmitting function, a diversity function, or an error correcting function used in mobile communication to overcome a situation in which a barcode such as a refraction of a plastic packaging material or the like is difficult to recognize.

Specifically, the radiating unit 311 is installed at a plurality of positions on each side of the mobile smart cart 210, and radiates a plurality of optical signals for barcode recognition to all areas within the mobile smart cart 210 . The radiation unit 311 radiates a code signal of a predetermined type in an optical signal according to a pilot transmission function, rather than merely radiating a general optical signal. Then, the receiving unit 312 receives the optical signal and corrects the distortion due to the reflection of the packaging material by using the code signal included in the received optical signal, thereby accurately recognizing the bar code. Since the mobile smart cart 210 has a plurality of radiation units 311 and a plurality of reception units 312, the mobile smart cart 210 drives each radiation unit 311 with a time deviation, (311) are differently set, and all the receiving units (312) analyze the codes to enable more accurate barcode recognition. This is similar to a method for improving the quality of a signal by constructing a dual receiver in a mobile communication system. The mobile communication techniques include a switching method, an equal gain method, a maximum ratio combining method, and the like. However, since it is different from the fundamental idea of the present invention, a detailed description thereof will be omitted.

A plurality of reception units 312 are installed in the mobile smart cart 210. An optical signal emitted from each radiation unit 311 receives an optical signal reflected on a barcode attached to a surface of a product to recognize the barcode. The diversity function of the receiver 312 may be concretely performed by simultaneously driving a plurality of radiation units 311 and a plurality of reception units 312. The plurality of radiation units 311 may transmit a code of each radiation unit in advance Emit at the set value. Each receiving unit 312 simultaneously receives the signals and analyzes the channels in the mobile smart cart 210 by comparing the matrices of the codes included in the optical signals emitted from the radiation unit 311 with the matrix of the received codes, A more accurate bar code signal can be analyzed for the reflected optical signal. The mobile smart cart 210 recognizes the optical channel model in the mobile smart cart 210 in a state where the goods are present in the mobile smart cart 210 or in a non-existent state. When a new product is inserted, the plurality of radiation units 311 and the plurality of receiving units 312 estimate the channel model of the currently input commodity using the previously recognized channel model. The plurality of radiation units 311 and the plurality of reception units 312 use this to analyze what a bar code of a new product is and recognize a bar code of a new product. This is similar to a method in which a transmission error can be reduced or a transmission capacity can be increased by utilizing a plurality of transmission antennas and a plurality of reception antennas in a mobile communication system. In the present invention, since it is not an object to increase the transmission capacity, a method of reducing the transmission error is used to reduce the recognition error of the bar code.

Specifically, the error correction function estimates the most similar bar code among bar codes of a predetermined product when the receiving unit 312 in the mobile smart cart 210 recognizes the bar code. Here, if the receiving unit 312 correctly recognizes the bar code, the error correcting function does not apply. However, if the mobile smart cart 210 recognizes the barcode but the corresponding product is not in the barcode storage information, the error correction function recognizes the recognized barcode as the barcode of the most similar type among the pre-stored barcodes. This is similar to the error correction function that automatically converts the received 0 and 1 into the most similar form by taking advantage of the digital communication of 0 and 1 in the mobile communication system. The error correcting function also includes a function of automatically radiating a code of a known type by the radiating unit 311 and correcting the error automatically using a code of a type previously known by the receiving unit 312 . These algorithms are used in Wiener and Least Mean Square algorithms in mobile communication systems, and a detailed description thereof will be omitted.

The wireless communication unit 320 requests the store server 220 through the wireless communication network to settle the goods information and the goods corresponding to the barcode recognized by the barcode recognition unit 310, and receives the goods information and the payment completion information. That is, the wireless communication unit 320 receives the merchandise information corresponding to the barcode recognized by the receiving unit 312 by requesting the store server 220 through the wireless communication network. The wireless communication unit 320 enables the price of a product to be confirmed through wireless communication as soon as the product is inserted. The wireless communication unit 320 is connected to the store server 220 using a wireless communication network (for example, a network of a mobile communication provider) and receives the type and price of the product at the moment when the product is inserted. In addition, the wireless communication unit 320 requests the settlement server 220 through the wireless communication network for settlement of the commodity which has been calculated so far according to the settlement request command of the user, and receives the settlement completion signal from the store server 220 . For example, the wireless communication unit 320 can use any form such as Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), and Wireless Broadband (WiBro) The system is suitable.

The user interface unit 330 receives a user command from a user, and displays product information or payment completion information received by the wireless communication unit 320 to a user. That is, the user interface unit 330 displays the payment for the goods information and the goods delivered from the wireless communication unit 320 to the user. In addition, the user interface unit 330 receives a purchase cancellation request, a payment request, and a cancellation command for a product from a user. In accordance with the payment request command of the user, the user interface unit 330 requests payment through the wireless communication unit 320 for the goods that have been calculated so far. Here, the user interface unit 330 displays the goods information and the payment completion information transmitted from the wireless communication unit 320 through the liquid crystal display mounted externally. Therefore, the user interface unit 330 can confirm to the user that the goods are recognized or paid.

The power supply unit 340 applies power to the mobile smart cart 210 to drive the barcode recognition unit 310, the wireless communication unit 320, and the user interface unit 330. The power supply unit 340 uses a DC power source in view of the characteristics of the mobile smart cart 210, and includes a battery (e.g., a battery) for this purpose. Here, the capacity of the battery requires more than the average purchase time of the customer, but the excessive capacity can make the weight of the cart too heavy. Therefore, the capacity of the battery is analyzed by the user's fitness and the purchase activity time so as to have the optimum capacity.

Meanwhile, if the barcode can not be recognized when a product is inserted into the slot for preventing theft of the mobile smart cart 210, the user interface unit 330 may generate an alarm signal. In addition, a separate bar code reader may be installed in the mobile smart cart 210 so that the user can manually recognize the product manually. However, such an alarm signal generating function or a separate bar code reader is merely an auxiliary means of the present invention, and the present invention is not limited to this auxiliary means.

4 is a detailed block diagram of an embodiment of the barcode recognition unit of FIG. 3 according to the present invention.

As shown in FIG. 4, the mobile smart cart 210 is similar to a shopping cart of a mart or store where its shape is generally used. The mobile smart cart 210 has a form in which a cover 402 with a slot 401 is provided in a general shopping cart.

In the mobile smart cart 210, a plurality of radiation units and a reception unit 410 are installed on six sides except the input port 401. The bar code can be recognized by a plurality of radiation units and receiving units 410 installed on six sides of the mobile smart cart 210 regardless of the product bar code inserted through the input port 401. Here, the region 411 to be radiated is set to include all the areas inside the mobile smart cart 210.

5 is a flowchart illustrating a method of purchasing a product using a mobile smart cart according to an embodiment of the present invention.

How to purchase products using mobile smart cart is as follows.

The user drives the power of the mobile smart cart 210 provided in the large-sized shopping mall (502).

Then, the mobile smart cart 210 drives the barcode recognition unit 310 for the first time to recognize the barcode of the goods. That is, the mobile smart cart 210 drives the plurality of radiation units 311 and the receiving unit 312 (504). In accordance with this driving, the mobile smart cart 210 inserts a predetermined radiation code into a plurality of optical signals for bar code recognition to emit an optical signal with a time deviation within the mobile smart cart 210. [

Then, the mobile smart cart 210 starts the purchase activity at the store and receives the goods into the input port 401 of the mobile smart cart 210 (506).

Then, the mobile smart cart 210 attempts to recognize the barcode of the goods by the plurality of radiation units 311 and the reception unit 312 (508).

The mobile smart cart 210 checks whether the barcode of the goods is recognized (510). Here, the mobile smart cart 210 analyzes the initial channel analysis and the changed channel in the mobile smart cart 210 to recognize the barcode of the commodity inputted by the user, and uses the pilot function, the diversity function, or the error correction function It recognizes the barcode.

Specifically, the mobile smart cart 210 radiates a predetermined radiation code into the optical signal for barcode recognition and emits the radiation code, and sets a different radiation code for each radiation part 311, . In addition, the mobile smart cart 210 inserts and radiates a predetermined radiation code into a plurality of optical signals for bar code recognition, receives all the optical signals reflected from the bar code emitted from the plurality of radiation units 311, The bar code is recognized through channel analysis. In addition, if the recognized barcode is not in the barcode list of the predefined goods, the mobile smart cart 210 estimates the recognized barcode as the most similar barcode among the barcode of the predetermined product.

If the bar code of the product is not recognized (510), the mobile smart cart 210 generates a recognition error alarm (512). Here, the user can manually recognize the barcode of the product using the manual barcode recognition unit and input the recognized barcode into the mobile smart cart 210.

On the other hand, if it is determined in step 510 that the barcode of the product is recognized, the mobile smart cart 210 transmits the recognized barcode information to the store server 220 via wireless communication with the store server 220, The product information is received and displayed (514).

If a plurality of goods are recognized, the mobile smart cart 210 completes the calculation for the whole goods (516).

The mobile smart cart 210 receives a request for remote settlement of the calculated goods from the user in the mobile smart cart 210 (518). In addition, the user can request remote payment to the mobile card server for the goods that have been calculated in the mobile smart cart 210. Here, the user refers to a customer who is subscribed to the mobile card service in advance.

The mobile smart cart 210 is notified of the settlement of payment through interlocking between the goods settlement server 230 and the store server 220 when the user pays for the goods through the wireless communication between the settlement servers 230.

The foregoing description is merely illustrative of the present invention, and various modifications may be made by those skilled in the art without departing from the spirit of the present invention. Accordingly, the embodiments disclosed in the specification of the present invention are not intended to limit the present invention. The scope of the present invention should be construed according to the following claims, and all the techniques within the scope of equivalents should be construed as being included in the scope of the present invention.
