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

1 is a schematic diagram illustrating the concept of the present invention.

The present invention comprises a user's wireless terminal 400, a central server system 100, a local server system 200, a data transmission and reception system 300 and a wireless tag 500.

One of the features of the system of the present invention is to obtain information stored in the wireless tag 500 attached to each product by using the user's wireless terminal 400.

The radio tag 500 stores information related to the product, such as a product name, a date of manufacture, a manufacturer, a description of a product, and a product distribution process of each product, and is attached to a product that is the subject of the information.

The information stored in the radio tag 500 may include 3D graphic information that may well represent the characteristics of the product. In general text information, there is a drawback that people who search for it do not immediately catch the eye, so if you include 3D graphics information, such as graphics representing the appearance of the product, people viewing the information stored in the wireless tag 500 outputs the information. It is desirable to see what kind of product the product is.

The radio tag 500 has its own power supply so that information about data can be transmitted continuously or when a predetermined signal is received. The radio tag 500 generates power by using a predetermined received radio wave, and generates power. It is also possible to transmit the stored information using. In general, the RFID (Radio Frequency IDentification) tag that can be used as a radio tag 500 includes a direct power source or a technology for generating a power source by receiving a radio wave is a well known technology, and thus a detailed description thereof will be omitted here.

In addition, the wireless tag 500 may simply have a function of transmitting data stored in the memory, but it is preferable that a product capable of newly storing or changing the contents of the data included in the transmitted signal in the memory may be used. . Since a technique of using a writable memory and writing data to the memory is already implemented in a general computer, a description thereof will be omitted.

The data transmission and reception system 300 receives information stored in the wireless tag 500 through communication with the wireless tag 500 and transmits the information stored in the wireless tag 500 to the central server system 100 or the local server system 200.

The data transmission and reception system 300 should be installed in an appropriate number at a distance capable of wireless communication with the wireless tag 500. The data transmission and reception system 300 should be installed at an appropriate number of distances, such as a warehouse, a sales store, etc., in which a product with the wireless tag 500 is stored.

For example, when the communication distance between the data transmission and reception system 300 and the wireless tag 500 is 5 m, the data transmission and reception system 300 may communicate with the wireless tag 500 in a circle having a diameter of 10 m, and thus 10 m intervals. It is preferable to install.

The communication distance between the data transmission and reception system 300 and the wireless tag 500 varies depending on the strength, frequency, and the like of radio waves used for transmission. In general, the stronger the strength of the radio wave, the higher the frequency, the longer the communication becomes possible.

It is also possible to move the data transmission and reception system 300 arbitrarily without fixing it in one place. Since the range of products that can provide the product information to the user will be limited to the product at a distance that can be communicated by the data transmission and reception system 300, the service provider who provides the service of the present invention to the user The data transmission and reception system 300 may be installed at a desired location. Therefore, if the item to provide a service, that is, to change the item to provide the product information to the user remotely will be installed by moving the data transmission and reception system 300 in the position where the product to provide a new product information.

When the wireless tag 500 does not have its own power when the data transmission and reception system 300 and the wireless tag 500 communicate, first, the data transmission and reception system 300 may generate power to the wireless tag 500. Transmit the information stored in the memory to the data transmission / reception system 300 using the power generated by the radio tag 500 using this radio wave, or transmit the data transmitted from the data transmission / reception system 300 to the internal memory. To save it.

On the other hand, when the wireless tag 500 has its own power built-in, the wireless tag 500 is always set to transmit the data stored in the memory or when receiving a specific signal, the data transmission and reception system 300 Receives the transmitted data when the radio tag 500 is always set to transmit data, and transmits data when the radio tag 500 receives a specific signal. After the transmission / reception system 300 sends a signal corresponding to the radio tag 500, the radio tag 500 receiving the signal transmits the data stored in the memory.

The process for changing the data stored in the radio tag 500 or storing new data is similar to the above process.

That is, when the wireless tag 500 does not have its own power, the data transmission and reception system 300 sequentially or simultaneously transmits radio waves and data to be recorded to generate power in the wireless tag 500, thereby simultaneously transmitting the wireless tag. Since the data received in the 500 is recorded, and if the wireless tag 500 has its own power supply, the data to be recorded is transmitted by transmitting only the data to be recorded since the wireless tag 500 will always be in a standby state. After receiving the data to be recorded once, the operation inside the wireless tag 500 goes through the same process as storing data in a memory or the like in a general computer.

When a plurality of radio tags 500 exist around one data transmission / reception system 300, the communication method between the data transmission / reception system 300 and the radio tag 500 is simultaneously within the communication distance of the RFID reader in the conventional distribution process. When a plurality of RFID tags are located, any method of identifying the RFID of attention by the RFID reader may be used, and the method is not limited.

For example, the data transmission and reception system 300 receives the respective identification codes from the wireless tag 500 having a unique identification code in the wireless tag 500 located around the order to transmit to each wireless tag 500 based on this. The radio tag 500 transmits its own data only when a signal corresponding to its own identification code is transmitted, thereby preventing a collision.

The data transmission / reception system 300 transmits the data received from the surrounding wireless tag 500 to the local server system 200 using the received data as a phrase or by using the received data.

When generating new data using the data received from the radio tag 500, it is preferable to include a task of performing classification and analysis processing of the received data.

For example, there are 20 radio tags at a communication distance of one data transmission / reception system 300, 10 are attached to the A product, and 10 are attached to the B product, so that 10 of the received data are Data transmission and reception system 300 when a product serial number is information about a product from A001 to A010 and 10 items are information about a product B and a serial number is information about a product from B001 to B010. Classifies data about product A and data about product B, extracts common information about the name of A product, manufacturer, and brief description of the product from the classified data about A product, and uses the received data. A is to extract the quantity of products and generate data that combines the extracted information and the unique parts of each data, such as serial number, production date, and expiration date of each product. And data relating to the product B is also through the same process may perform a process of creating the data of the B product.

The operation of generating new data by collecting and analyzing data received from the radio tag 500 may be performed directly in the data transmission / reception system 300, but may be performed in the local server system 200 or the central server system 100. It may be. Where to process the data can be chosen arbitrarily by the designer of the system.

The data transmission and reception system 300 and the local server system 200 perform communication through wired or wireless communication.

The regional server system 200 is a server system that is in charge of communication with the data transmission and reception system 300 in a predetermined region, and is generally installed in a specific store, such as a large mart, as one logistic warehouse unit, and the data transmission and reception system in the corresponding area. Receiving the data from the (300) can be responsible for the quantity management of the product.

The central server system 100 receives the user's request input through the user's wireless terminal 400 and transmits it to the corresponding local server system 200, the local server system 200 is a data transmission and reception system ( 300 to receive the necessary data from the radio tag 500, or to record the data necessary for the radio tag 500.

In FIG. 1, the central server system 100 and the local server system 200 are illustrated as separate systems, but may be configured as one system. That is, in FIG. 1, the central server system 100 is mainly responsible for communication with the user's wireless terminal 400, and the local server system 200 is mainly responsible for communication with the data transmission / reception system 300. For example, one server system can be configured to handle both functions.

For example, one central server system 100 may be configured to communicate directly with all data transmission and reception systems 300, and a plurality of local server systems 200 may divide each zone to provide a data transmission and reception system within the zone. 300, and if the user wants to read data stored in the wireless tag 500 or write data to the wireless tag 500, the local server system 200 in the area where the corresponding wireless tag 500 is located. It may be connected to perform the above operation.

In the case of dividing the central server system 100 and the local server system 200, all the contents transmitted by the user through his wireless terminal 400 are received by the central server system 100, and the central server system 100 ) Selects a corresponding region based on the received contents, and transmits the user's request to the regional server system 200 located in the selected region.

A user may designate a store, a warehouse, a region, etc. to obtain information and transmit the information to a central server system 100 in order to obtain information of a desired product, or simply transmit information about a desired product to the central server system 100. The user's location is tracked and the user's request is sent to the local server system 200 located in the area where the user is located.

A detailed configuration will be described with reference to FIG. 2.

Figure 2 is a block diagram showing the functional components of the system of the present invention. The system of the present invention includes not only a function of reading data from the radio tag 500 and providing the information to the user, but also a function of recording data input by the user in the radio tag 500. However, for convenience of explanation, the description of each component below will focus on the function of providing product information to the user, and the function of recording data will be mainly described in FIG. 4 and will be briefly described herein.

Wireless tag information providing system of the present invention is a user connection unit 101, data transmission unit 102, location information confirmation unit 103, data generation unit 104, wireless tag communication unit 105 and product location information storage unit ( 106).

The user connection unit 101 exchanges data with the user's wireless terminal 400 through wireless communication. The user connection unit 101 is provided in the central server system 100 when the central server system 100 and the local server system 200 are integrated, and in the central server system 100 when the central server system 100 is integrated.

The user inputs product information and region information he / she wants through his wireless terminal 400, or inputs only product information to the user connection unit 101, and transmits the desired product information to the user connection unit 101. Is received through).

If the user does not input the region information, it is preferable to provide product information of the region where the user is located. The user's location information is identified through GPS, base station tracking, and the like, and the current location of the user can be known by receiving the identified location information from the user's wireless terminal 400 or a communication company system.

Whether the user must enter the desired local information, or if the user does not enter the local information, the product information is provided centered on the location where the user is located, or the user's product information is always provided only in the area where the user is located. Whether to omit the process of inputting the desired area information to the user may be arbitrarily set by the system design of the system designer or the setting of the user terminal.

There may be a variety of ways for the user to request the desired product information. For example, the product information may be requested by designating a specific product type such as a computer or a monitor, or the product information may be requested by designating a specific manufacturer and product type.

In addition, when the user specifies the regional information, the region may be designated in units of administrative regions, or the product information may be requested by specifying a more specific region such as a specific store name.

You can also request product information without specifying a region. For example, if a user wants to purchase a product produced by Company A in consideration of the distance and price from the user to the store, the user can request product information by specifying only the product name, and a product is sold among the received information. By comparing the locations of stores being sold, the prices of a products sold in each store, you can decide which stores to purchase.

On the other hand, the user connection unit 101 receives the user's connection even if the user wants to record data in the radio tag that has the recording authority.

By using the user's terminal, the user basically transmits the product to record data and the contents of the data to be recorded, and in some cases, also transmits the region information where the product to record data is located to the user access unit 101 as well. .

The user connection unit 101 preferably performs a separate authentication process to determine whether the user requesting the recording of data has the authority to record the data in the requesting product.

The positioning unit 103 checks the position of the user's wireless terminal 400. The positioning unit 103 is provided in the integrated server system when the central server system 100 and the local server system 200 are integrated, and in the central server system 100 when the central server system 100 is integrated.

As described above, the location of the user wireless terminal 400 can be known through a conventional location tracking method such as GPS and base station tracking, and the positioning unit 103 can be obtained from the user's wireless terminal 400 or a communication company. Receive information about the location of the user's wireless terminal 400 from the system (not shown) to confirm the location of the user.

The data transmission unit 102 is in charge of communication with the wireless tag communication unit 105, and when the user receives the information request for the product requesting the user information received by the user connection unit 101, the user enters the local information Receive information about the area where the user requested the product information from the user connection unit 101, otherwise determine the current location of the user identified through the positioning unit 103, and transmit and receive data located in the corresponding area The product information is requested to the wireless tag communication unit 105 of the system 300 and received and provided to the user connection unit 101.

The data transmission unit 102 is installed in the integrated server system when the central server system 100 and the local server system 200 are integrated, or in the local server system 200 when the central server system 100 is integrated, or the central server system. System 100 and the local server system 200 may be configured in an integrated form. That is, the central server system 100 may be in charge of selecting a region to request product information, and the local server system 200 may be in direct communication with the wireless tag communication unit 105.

Meanwhile, when a data recording request is received from the user, the data transmission unit 102 selects the wireless tag communication unit 105 to attempt communication with the wireless tag 500 attached to the product by using the product information input by the user. The operation is performed, and the selected wireless tag communication unit 105 is requested to record data requested by the user.

At this time, if the user does not enter local information, the requested data should be recorded in all radio tags that can communicate, or if the user has different recording authority for each radio tag, the radio attached to the product with the user's recording authority It is desirable to make the recording only if the user has the recording authority through the process of checking whether it is a tag.

When the user designates the region information, the above operation is performed only in the region designated by the user.

The radio tag communication unit 105 communicates with the data transmission unit 102 and the radio tag 500 and is installed in the data transmission / reception system 300. When the wireless tag communication unit 105 receives a request for information about a product from the data transmission unit 102, it communicates with the wireless tag 500 to receive the information and transmits the information back to the data transmission unit 102.

The communication method between the radio tag communication unit 105 and the radio tag 500 is as described above. That is, when the wireless tag 500 does not have its own power source, the wireless tag 500 transmits signals for data transmission and power generation. When the wireless tag 500 generates power using the received signal and transmits data, the wireless tag 500 transmits the data. If the wireless tag 500 has its own power source, the wireless tag 500 transmits a signal for requesting transmission of stored data, and communicates with the wireless tag 500 by receiving a signal corresponding thereto.

Meanwhile, when the user requests recording of data, the wireless tag communication unit 105 records the data requested by the user in a product designated by the user. The process of recording data in the radio tag through the radio tag communication unit 105 is the same as the process of recording data in the RFID tag using a general RFID writer except for selecting a radio tag to be recorded.

The product location information storage unit 106 stores information about the location of each product in each warehouse, store, etc., where a service can be provided. That is, the information on the type of products located in the communication distance for each radio tag communication unit 105 is stored. The product location information storage unit 106 is the central server system 100 and the local server system 200 is integrated in the integrated server system, if separated, the central server system 100 and the local server system It can be installed in either one of the 200.

In general, since warehouses, stores, etc. always have the same kind of products in the same location, storing the location in advance can prevent unnecessary communication traffic.

For example, if a user requests information about a computer of company A provided in a specific large mart, and there is no information about where the computer of company A is located, the data transmission unit 102 is installed in the mart. After receiving all the information stored in the wireless tag of all products through all the wireless tag communication unit 105, only the information about the computer of Company A is provided to the user, where the computer of Company A in the mart In the case where it is possible to know whether it is located, the data transmission unit 102 needs to request the product information only in the wireless tag communication unit 105 where the product is located. In this case, a lot of data can be prevented from being transmitted.

When a product information request is received for a product that can be identified by the product location information storage unit 106, the data transmission unit 102 uses location information of each product stored in the product location information storage unit 106. By requesting to provide the product information only to the radio tag communication unit 105 that can communicate with the radio tag of the corresponding product, and thus the remaining radio tag communication unit 105 does not perform unnecessary operations.

Meanwhile, the product location information storage unit 106 also specifies a list of products for which each user has a recording authority and information about a region in which the product is located.

When the above information is stored in the product location information storage unit 106, even if the user requests to record data in the radio tag and does not determine the area information, the data transmission unit 102 stores the product location information storage unit ( In 106, the wireless tag communication unit 105 may select a wireless tag communication unit 105 to be used for communication with the wireless tag by extracting a list of products for which the user has a recording authority and information on a region where the product is located.

The data generator 104 generates data to be transmitted to the user by using the data received from the radio tag 500. The data generation unit 104 may be installed and operated in any one system of the data transmission and reception system 300, the local server system 200, and the central server system 100.

There is no limitation on how the data generation unit 104 generates data.

For example, in the simplest method, only the information about the product desired by the user may be extracted from the data received from the radio tag 500 so that the information is continuously listed. For example, if there are 20 products of information desired by a user in a region designated by the user, data may be generated by simply listing information received from the radio tag 500 attached to the 20 products.

Alternatively, data may be generated by extracting and statistically processing common parts of the received information and listing all or part of the unique information for each product. For example, there are 20 products you want in the region you want, 10 products from Company A with serial numbers from A001 to A010, and 10 products from Company B with serial numbers from B001 to B010. The data generation unit 104 classifies the data regarding the company A product and the data about the company B product, and the name of the product A, the manufacturer, and a brief description of the product. Extract the common content of the product, extract the quantity of the A product using the received data, and extract the information and the unique part of each data, such as the serial number, production date, and expiration date of each product. Produces data integrating the data, and the data for the product B can also generate the data of the product B by performing the same process through the same process.

At this time, the data generation unit 104 may generate data using only some of the data received from the radio tag 500. When data is generated using only some of the information received from the radio tag 500, the criteria for generating new data may be set by the system designer or may be set by the user.

For example, when the information of interest to the user is the price of the product desired by the user, the data generated by the data generator 104 may include only basic information and price information of the product from which the information is received. have.

In this way, when the user requests the product information, the type of information to be provided in advance can be specified so that only the desired information can be received from the product information. As a system, data traffic can be reduced, and the user can simply It is desirable to be able to see only the information he wants.

The method of the present invention is described with reference to FIG. 3 is a flow chart illustrating a method of the present invention.

The user wants to know whether the product he wants is sold in a specific region, how much is the selling price, how much is stored, and how long is the shelf life of the product in the region specified by the user if the product has an expiration date? For example, when information stored in the wireless tag 500 of each product is desired, a message for requesting product information is transmitted to the user access unit 101 by using the wireless terminal 400 of the user (301).

At this time, the user can transmit the message requesting the product information to the user connection unit 101 can be arbitrarily set by the system designer, there is no particular limitation. For example, the user may request the product information by inputting or selecting information necessary for accessing the user connection unit 101 and requesting the product information through the wireless Internet, or request the product information in the form of sending a short message. It may be. When requesting product information by using a short message, the user connection unit 101 is preferably provided with a program capable of parsing and extracting necessary information from a message sent by the user.

When a user sends a message requesting product information that he / she wants information, the user may simply enter product information such as a desired product name, may enter product information and local information together, or other information that the user specifically wants to receive ( For example, the price of the product, the expiration date of the product, etc.) can also be entered.

If the user does not input the region information, it is preferable that the region desired by the user is regarded as the region where the user is currently located and used as the region information. The positioning unit 103 receives the location information of the user from the user's wireless terminal 400 or the mobile communication company system to confirm the location of the user (not shown).

When the product information transmission request is received from the user, the data transmission unit 102 is wirelessly attached to the product using the product information input by the user and the user location identified through the local information or the positioning unit 103 input by the user. In operation 302, the wireless tag communication unit 105 to attempt communication with the tag 500 is selected.

As described above, when the central server system 100 and the local server system 200 are operated separately from the system of the present invention, the central server system 100 first obtains the local server system 200 to obtain product information.

It is preferable to select the radio tag communication unit 105 to be used. In this case, it is preferable to prevent unnecessary communication with the wireless tag 500 attached to a product other than the product desired by the user.

When the storage location of the product selected by the user is not stored in the product location information storage unit 106, all wireless tag communication units 105 located in a desired area of the user are selected to communicate with the wireless tag 500.

When the radio tag communication unit 105 to communicate with the radio tag 500 is selected, the data transmission unit 102 communicates with the radio tag 500 in the radio tag communication unit 105 and stores the radio tag 500 in the radio tag 500. It is requested to obtain the information (303).

In response to the request, the wireless tag communication unit 105 sends a signal to the wireless tag 500 at a distance from which it can communicate to obtain information stored from the wireless tag 500 (304).

In the case where the wireless tag 500 has its own power source and when there is no power source, the communication method in each case has already been described above, and thus, a detailed description thereof will be omitted.

When the radio tag communication unit 105 obtains the information of the product from the radio tag 500, the data generation unit 104 generates data to be transmitted to the user using the obtained information (305).

When generating data to be transmitted to a user, first, product information corresponding to a product designated by a user is extracted from the received product information, and data is generated using the extracted information.

When generating data, it is possible to simply extract information about the product desired by the user from the data received from the radio tag 500 so that this information is continuously listed, and extract and statistically process a common part of the received information. We have already seen that there is no limit to the method, such as generating data by listing all or part of unique information for each product.

In addition, when generating data using only a part of the received information, as described above, the partial information used to generate the data may be determined by the system designer or the user who requested the product information.

When the data to be provided to the user is generated, the data is transmitted to the user's wireless terminal 400 through the user connection unit 101, the user sees the content output to his wireless terminal 400, the area selected by the user It is possible to know various product information, such as whether there is a product desired by the user, how much the price is, and where the freshest product is sold (306).

In the above description, the user has focused on the part of acquiring the product information. However, when the wireless tag 500 attached to the product has a writable memory, the user can remotely search for the wireless tag of each product at a remote location. It is also possible to enter the information directly into 500).

In this case, most of the users will be directly involved in the distribution and sales process, and the recorded data will be data related to the distribution record of the product or data for promotion of the product.

4 is a flowchart illustrating a method of recording data in a wireless tag 500 attached to a product at a remote location.

The user first designates a product he wants to record data for, the content of the data to be recorded, a region, and the like, and transmits a message requesting data recording to the user access unit 101 (401).

At this time, the user can transmit the message requesting the data recording to the user connection unit 101 can be arbitrarily set by the system designer, and there is no particular limitation as shown in FIG. However, in general, since the right to record data in the wireless tag 500 is limited to only a few people, the user connection unit 101 preferably performs user authentication through a separate authentication process when receiving a user's message. something to do. Since it is a well-known technique for authenticating online, a detailed description thereof is omitted here.

When the data recording request is received from the user, the data transmission unit 102 may attempt to communicate with the wireless tag 500 attached to the product by using the product information input by the user and the region information input by the user. (402).

In this case, when the user does not input the region information, the region information may be extracted using the user information authenticated through the user access unit 101. That is, the product location information storage unit 106 stores a list of products for which each user has permission to record and information on the region where the product is located, and extracts a product designated by the user from the list of products for which the user has permission to record. For example, it may be possible to extract local information by extracting the area where the product is located.

When the user requests recording of data, the user must input product information and region information in addition to the data to be recorded, and the data transmission unit 102 selects the wireless tag communication unit 105 to be used for data recording based on this. It is not limited to this.

For example, if a manufacturer producing a wireless tag used in the system of the present invention wants to change the basic format of data recorded in the wireless tag, the entire area of the service area regardless of the type or region of the product. In this case, you will not need to receive information about the type or region of the product, since you will be asked to record the data in a radio tag attached to the product.

As another example, using the information stored in the product location information storage unit 106, even if the user does not specify the region or product, it will be possible to record data to all of the wireless tags attached to the products that have permission to record. will be. If the user specifies only local information or product information, the data may be recorded only in a product in which the user has the right to record, the product located in a specific region, or a wireless tag attached to a specific type of product. .

When the wireless tag communication unit 105 to communicate with the wireless tag 500 is selected, the data transmission unit 102 communicates with the wireless tag 500 to the selected wireless tag communication unit 105 to user the wireless tag 500. Command to record the entered data (403).

In order for the wireless tag communication unit 105 to record data, the wireless tag 500 selects whether there is a product designated by the user among the wireless tags 500 located within the communicable distance, and, if there is a product designated by the user, the wireless tag 500 attached to the product. Only the data entered by the user is recorded.

When there are a plurality of radio tags 500 within the communication range of the radio tag communication unit 105 such as a radio tag reader, the radio tag 500 communicates with each radio tag and uses specific radio tag identification information such as serial number. Since a technique for recording desired data only in a tag is already well known, a detailed description thereof will be omitted.

When the data input by the user in the wireless tag 500 is recorded, the user may request product information through the same process as in FIG. 3, view the received information, and check whether the desired data has been recorded. Even if the user does not directly request the product information, the data recorded in the wireless tag 500 may be set to be transmitted to the user's wireless terminal 400 so that the user may check the result of the operation requested by the user.
