Figure 3 is a block diagram of the indicator system, Figure 3 shows a block diagram of the goods display rack in the system for managing and selling goods according to the present invention, as shown,

The present invention provides a display rack comprising a display module (1) having a unique ID (ID), a display box (3) provided with the display module and the RFID reader (2), and an RFID tag having a unique ID. It is roughly divided into attached goods, proximity RFID tags that the buyer wears but have a unique ID, and a central server computer that manages the location and payment of the carts and goods installed with the RFID reader.

In this configuration, the indicator module uses an LED or LCD indicator module that is configured in a rectangular shape and extends in a vertical or horizontal direction, and when installed adjacently in a vertical or horizontal direction, a serial communication line. It is possible to connect in daisy chain form, so that display signal information and power can be applied to all connected indicator modules in the last indicator module, and each of these indicator modules has a barcode reader or RFID ID. (RF ID) The reader is mounted on the back.

In addition, the LED or the LCD display module has a function to cut off the power to reduce power consumption during the idle period of the shop, the display displayed by the LED or the LCD is the display itself in the case of selling or discounting the goods Can flash or display a different color.

In addition, the display rack in which the indicator module 1 is installed is composed of a display compartment 3 divided into several compartments by a separation compartment, but the separation compartment of the display compartment is metallic and for the electromagnetic separation from adjacent display compartments. It should be made of a magnetic field blocking material or the like, thereby preventing the RFID reader 2 from recognizing the RFID tag of an adjacent display rack article, which will be described later, and the display module and the display rack installed on the front of the display rack. Reader antennas (4) should be installed in several places along the floor and around the shelf so that the RFID tags attached to all items in the shelf (3) can be easily recognized.

In addition, if there is a concern that the reflection of the RF reader or the receiver of the RFID tag may be reduced due to severe electromagnetic reflection due to the metal / magnetic material of the display compartment, the reflection wave may be wrapped around the display compartment with an electromagnetic attenuating material.

In addition, the RF tag is attached to the RFID reader installed in the display module in a variety of articles displayed on the shelves of the shelves, and each article has a unique ID.

In addition, the proximity RFID tag that the buyer of the item must always wear and carry in the store also includes a unique ID. When the buyer selects one of the items displayed on the shelves, the proximity RFID tag held by the buyer Is recognized by the RF reader of the display rack and generates a corresponding beep sound.

In particular, in the above configuration, the reader antenna installed on the bottom of the shelf makes it easy to recognize the RFID tags of all the items thereon, and the reader antenna installed on the indicator module on the front side of the shelf faces toward the front side. Must provide sufficient output and sensitivity to RF tags being used.

In addition, an RFID reader is installed in the cart holding the item selected by the buyer as in the indicator module, and the RFID reader recognizes the RFID tag attached to the item when the item selected by the buyer is contained in the cart. It can recognize unique ID of.

The central server computer connected to each other by wires or wireless LANs is configured to recognize the ID of the RFID tag attached to the goods when the RFID reader installed in the display module is displayed on each display rack. Received by the reader signal by the, and displays the overall information about the corresponding item, such as the price to the display module by the display signal, and if the displayed item is selected and moved by the buyer immediately recognizes this Inventory and sales can be checked in real time, and control of this series of processing is done by embedded application software.

The process of automatically managing and selling goods by the configuration of the present invention configured as described above is as follows.

4 is a flowchart of ID recognition and sales management algorithm of a central server computer in a system for managing and selling goods according to the present invention, and FIG. 5 is a RFID ID for displaying goods in a system for managing and selling goods according to the present invention. ) Is a flow chart of a management and purchaser ID (ID) recognition algorithm, Figure 6 is a block diagram of a system for double-checking the goods in the cart through the gate-type antenna of the cash register in the management and sales automation system of goods according to the present invention As shown, as shown,

The barcode reader or RFID reader automatically recognizes the ID information of the article displayed in the display box of the display rack, and transmits the recognized reader signal to the central server computer using a serial communication line such as a wired or wireless LAN. The information is obtained and displayed on the indicator module.

Such an indicator module always knows the ID and number of RFID tags attached to the items displayed on the shelves of the shelves using the RFID reader, and warns the central server computer when the items are exhausted by the buyer's choice. You can send This function activates the function of the RFID reader in the display compartment and then displays the articles and deactivates the RFID reader when all the displayed articles are fully recognized by the RFID reader. At this time, the IDs of all recognized items are registered in the central server computer and stored in the ID storage device.

In addition, the common price of these items is input from the central server computer to the LED or LCD display module, and then activated the RFID reader once every regular interval (0.1 seconds) to display the ID and the buyer's ID By securing the ID, the purchaser goods purchase status database DB of the ID storage device and the central server computer is updated each time. That is, when the buyer moves the displayed items to the cart, the ID of the corresponding item is not recognized from the display rack, and thus the ID of the corresponding item is added as the buyer's ID.

When a buyer purchases an item from this display stand, if the buyer presents an ID number using a proximity RFID tag worn on the neck, the RFID reader recognizes the ID and stores it. When the ID is moved from the shelf to the cart, the ID of the item removed from the shelf is detected by an RFID reader, and the ID of the item is automatically linked to the purchaser's ID, and the contents are transmitted to the central server computer. After that, the central server computer automatically accumulates the list of purchase items accumulated in the ID number of the buyer and the price.

The cart can be equipped with an RFID reader so that when the goods are put into the cart, the list of goods, the price and the sum are made and displayed on the display board of the cart so that the buyer is always aware of the purchase status. At this time, the reader is connected to the central server computer and the wireless LAN to provide the price information of the goods and the buyer purchase status and always update the changed information.

When the buyer moves the cart to the payment window and pays, the central server computer has already prepared the purchase item list of the buyer, so a receipt is issued and the payment is made at the cash register. Subsequent payments are removed from the inventory of the central server computer, creating a new inventory database.

However, when the buyer does not use the proximity RF tag or the RFID tag of the article is not presented to the RFID reader and moves the article away from the shelves, the ID of the item displayed in the shelves of the shelves is worn by the buyer. Since the ID of the proximity RFID tag is changed without ID recognition, the central server computer detects this and enters the boundary state. When the ID of the article is detected by the RFID reader installed at the entrance, the alarm sounds.

If one buyer puts an item in the cart and the other buyer is nearby and the buyer's ID is recognized at the same time, or if two or more people make a purchase on the same shelf, they can I can't figure it out. In this case, the buyer's RFID tag uses a proximity RFID tag, and only one person can be recognized by the reader after purchasing the item, and a beep sounds when it is recognized.

In the payment window, a gate-type RFID reader antenna is installed to recognize the goods in the cart once again, so that the cart and the buyer can pass through it, comparing the match with the purchase list provided by the central server computer. You will make a payment. If there is a problem, the items in the cart are scanned and paid one by one, and the cart must be made of plastic so that the RF passes easily.

Since metallic items can block other items electromagnetically, these items should be separated and loaded at a distance from other items in the cart, and avoid overlapping metallic items and blocking one another by electromagnetic waves. The carts must be separated and loaded one by one.

When the shelf is jointly used as a pool of multiple items, an RF reader can be installed near the shelf to allow buyers to access the item to the RFID reader for individual pricing. In this case, the RFID reader near the display stand installs a reader antenna so that the distance and the sensing direction of the display stand are different from the display stand so that only the goods presented by the buyer react.

For items that are weighed by the scale and priced according to the weight, the RFID tag is placed on the display rack itself, and the buyer places the item on the electronic balance and the weight is multiplied by the price per kilogram provided by the RFID reader. So that it appears in the electronic price indicator. At this time, the RFID reader reads the ID from the RFID tag, receives price information per kilogram from the central server computer, automatically calculates the price by the multiplier in the electronic price display, and displays the price on the electronic price display. Presenting the buyer's proximity RFID tag to this RFID reader automatically enters the price into the buyer's purchase list by the central server computer, and when the RFID reader issues the RFID tag label, the buyer places the RFID tag on the item. Put it into the cart. If the salesman weighs the item, the buyer puts the RFID tag on the RFID reader, the price is displayed on the indicator, and the salesman attaches the RFID tag label to the package and delivers it to the buyer. The buyer loads the cart like any other item and takes the cart to the payment counter.

By the way, when there is an item as a single piece without a case, a wrapping paper or a box, each of them should be able to attach an RFID tag and be in a display rack.

The present invention described above is not limited to the above-described embodiment and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the technical spirit of the present invention. It will be evident to those who have knowledge of.

According to the system for managing and selling goods using the RFID of the present invention having the above objects and configurations, and the method for managing and selling the goods thereby,

By using the electronic display board as a substitute for the price tag, not only the central server computer in the center can update all the display panels in the store in a short time, but also display various messages such as display of discount sales and display of new products. In addition, when a bar code or an RFID tag is attached to an article, an RFID reader may be mounted on each display panel to configure an automatic price display display stand that receives price information corresponding to the ID from a central server computer and displays the information on the display panel.

In this case, the most up-to-date information about the item can be automatically displayed on the display panel even when the item is displayed on the display stand, and a large LCD monitor can be used to display more expensive and more diverse information about the product. The principle is as described above.

In addition, by using this system, material cost and labor cost can be drastically reduced in order to manage the ever-changing price and information on other goods. Also, since it is a display by active elements, the display strength is high and it is easily noticeable to consumers. In addition, the color can be displayed in various ways, which can make a good impression on consumers.

In addition, letters and other characters can be displayed freely, so that messages such as discount sales and new products can be delivered.Also, buyers' RFID tags can be recognized near the shelves or near goods that are intended to be purchased. By only paying at, the number of cashiers can be reduced first, so that the buyer does not have to wait in line at the cashier for a long time, saving unnecessary time.

In addition, the purchaser ID and movement from the shelves of the goods are recorded on the central server computer and continuously tracked, thereby preventing theft of the goods and reducing the loss of the goods.
