Description

Method and Apparatus for managing input and output of ITEMS using barcode and RFID TAG}

The present invention relates to product entry and exit management, and more particularly, to a product entry and exit management apparatus and method using a barcode and RFID.

Barcodes are a combination of letters and numbers in black and white bar-shaped symbols that are easily readable by computers and are used to enter data quickly. This bar-shaped bar code is automatically read by an optical mark reader. The bar code indicates a kind of product conforming to the Universal Product Code (UPS), or is used for point of sales system (POS) in a supermarket or the like. At this time, the price is displayed separately and is also used for book classification and identification.

However, such a bar code can record only a small amount of information such as the name or price of the item, and thus it is impossible to collect various pieces of information of the item from the bar code. For example, a bar code corresponding to a power of 7 represents 128 bits of binary data, and the item information that can be stored in the binary data is extremely small. In addition, due to the limitations of the bar code as described above, it is impossible to express the item information in the form of multimedia data including a moving picture, an image, a voice, etc. in addition to the text-based item information.

In addition, since the barcode is read using a hand scanner or a laser scanner, there is a limitation in the distance that the barcode-printed article must contact the barcode scanner.

On the other hand, RFID management system (radio frequency identification management system) is a system that can send and receive various data in a wireless manner using a constant frequency band. Such RFID can overcome the disadvantage that the magnetic or barcode need a specific display and the recognition rate gradually decreases over time due to damage or damage. As a result, RFID is rapidly replacing the traditional barcode and magnetic card market, and is emerging as a new solution in various fields such as access control, commute management, logistics management and parking management.

However, since the logistics management using the RFID management system requires an expensive RFID device, the cost required for the system configuration increases.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a product entry and exit management device using a bar code and RFID technology according to an embodiment of the present invention.

Referring to FIG. 1, the product entry / exit device using barcode and RFID technology includes a barcode scanner 120, a first RFID reader 130, a product management server 140, a database server 150, and a second RFID reader 170. And a classifier 180.

The barcode scanner 120 scans a barcode printed on a packing box 110 of a product received. Therefore, the barcode scanner 120 may be installed at a position where the goods are first loaded in the conveyor belt system for transporting the goods.

The first RFID reader 130 reads tag information of each product included in the packaging box. That is, the first RFID reader 130 receives tag information from an RFID tag previously attached to each product included in the packaging box. Here, the tag information includes a tag ID.

In this case, the first RFID reader 130 reads the RFID tag information pre-attached to each product included in the packaging box at substantially the same time.

The first RFID reader 130 transmits the received tag information (including the tag ID) to the product management server 140.

The product management server 140 receives and maps (matches) the scanned barcode information and tag information of each product included in the packaging box.

In this case, the barcode information and tag information are mapped as follows.

One packing box 110 has a plurality of products having the same barcode value. Therefore, tag information of each product is mapped to correspond to the same barcode value. For example, if there are 80 yellow short-sleeved T-shirts (size 100) in a packing box, the product management server 140 displays the tag information attached to each yellow short-sleeved T-shirt with a barcode value printed on the packing box. To match.

Therefore, by using the matched information, it is possible to obtain information about the product from a long distance in a non-contact manner while minimizing the change of the conventional system managed by a bar code.

The product management server 140 stores the matched barcode information and tag information in the database server 150.

Accordingly, the product management server 140 may search for barcode information from the tag information by using the matched barcode information and tag information.

At this time, the operator of the entry and exit device may designate a shipping address for each packing box and input the shipping address to the product management server 140 or the database server 150, and the delivery address designated by the operator is stored to correspond to the barcode information.

The information stored in the database server 150 may form an index in the form of tag information + barcode information. In addition, in consideration of the characteristics of the warehouse operation, the tag information of the product included in the same packing box may be configured to be located in the same block or adjacent blocks on the memory.

The second RFID reader 170 receives tag information of each product packaged in the shipping target packing box 160. That is, the second RFID reader 170 receives tag information from an RFID tag pre-attached to each product included in a packing box to be shipped.

In addition, the second RFID reader 170 transmits the received tag information to the product management server 140.

At this time, the product management server 140 receiving the tag information from the second RFID reader 170 searches the database server 150 and extracts the barcode information corresponding to the received tag information.

In this case, the barcode information extracted from the database server 150 may include delivery address information previously input by the operator.

The product management server 140 transmits the extracted barcode information to the classifier 180. In this case, the product management server 140 may update the product status according to the extracted barcode information. That is, the packaging box corresponding to the extracted barcode information may be regarded as shipped, and the inventory status may be corrected.

The classifier 180 receives the extracted barcode information, and accordingly, the classifying box 190 classifies the shipping target packing box 160 for each destination.

2 is a block diagram of a product entry and exit management apparatus using a bar code and RFID technology according to another embodiment of the present invention.

Referring to FIG. 2, the product entry / exit device using the barcode and RFID technology includes a barcode scanner 220, a first RFID reader 230, a product management server 240, a database server 250, and a second RFID reader 270. And a classifier 280.

In FIG. 2, the barcode scanner 220 and the first RFID reader 230 perform the same operations as the barcode scanner 120 and the first RFID reader 130 described with reference to FIG. 1.

Accordingly, the product management server 240 and the database server 250 may perform all the operations performed by the product management server 240 and the database server 250 described with reference to FIG. 1.

The second RFID reader 270 receives tag information of an RFID tag attached to a product for shipment. Here, it is assumed that the product for shipping is a product placed on a shipping table (or a conveyor belt for shipping).

In addition, the second RFID reader 270 transmits the received tag information to the product management server 240.

As described in the embodiment of FIG. 1, the tag information is matched with barcode information printed on the packaging box of the product at the time of receipt of the product.

The product management server 240 receives tag information from the second RFID reader 270.

The product management server 240 searches for the product classification information corresponding to the received tag information in the database server 250 and transmits the retrieved information to the classifier 280.

The product management server 240 may update the product status according to the retrieved product management information in a similar manner to the embodiment of FIG. 1.

The classifier 280 receives the searched product management information, and accordingly, the classifying point 290 classifies the shipment target product 260 by delivery address.

As such, the embodiment shown in FIG. 2 represents a shipping and receiving system for classifying delivery addresses for each product.

Therefore, the embodiment illustrated in FIG. 2 may be applied to a case where an operator of a goods receipt management system classifies a delivery address for each product.

As described above, the present invention is conventionally applicable to a system for performing product inbound and outbound product management using only a barcode and a barcode scanner.

Using only barcodes and barcode scanners, product entry and exit, the operator of the product status management system discards all existing systems and introduces an RFID system.

However, the present invention solves the above problems by additionally configuring a product management server, an RFID reader, and the like without using a barcode and a barcode scanner and without discarding the product status management system. It becomes possible.

(S320), matching the scanned barcode information and tag information of each product included in the packing box and storing the matched information (S330), and the step of recognizing the tag information of the product shipped (S340) and receiving the barcode information corresponding to the tag information of the product shipped to determine the classification direction of the product (S350).

Scanning and recognizing the barcode (S310) may be performed by the barcode scanners 120 and 220 as described above.

Recognizing the tag ID (S320) may be performed by the first RFID readers 130 and 230 as described above.

The storing of the matched information (S330) may be performed by the product management servers 140 and 240 as described above.

Here, the step of recognizing the tag information of the product shipped (S340) is to recognize the tag information of each of the products included in the packing box to be shipped or the tag information of one of the goods shipped.

Similarly, the step of determining the classification direction of the product (S350) may be performed in a packing box or a product unit.
