The present invention relates to an RFID management system and method, and more particularly, to check the status of remote RFID readers of different types (heterogeneous models) and turn on / off, output strength, and antenna. The present invention relates to an RFID management system and method that can control an RFID reader through a single integrated interface instead of an individual program provided by a equipment company.

RFID (Radio Frequency Identification) technology is one of non-contact recognition technologies that can recognize objects by identifying unique IDs using RF signals for each frequency band. RFID technology may consist of an RFID tag containing unique data, an RFID reader for reading the information of the RFID tag, and a series of computing systems for processing the data read by the RFID reader.

In general, an RFID tag is composed of a transponder chip and an antenna made of a semiconductor. The RFID tag is supplied with energy from an external radio signal (passive type) or is supplied with energy from its own battery (active type). Send the data. The RFID reader can obtain desired information by decoding and decoding the signal received through the antenna. The data obtained through the RFID tag and the reader is used as useful information by interworking with internal applications such as an enterprise. The information processing system using the RFID technology can be largely divided into a device layer, a middleware layer, and an application layer.

As described above, the device layer is composed of a tag that stores unique information (data) and a reader that reads and identifies information of the tag, and performs a function of collecting data of the tag. The middleware layer collects and filters tag data transmitted from the device layer to be effectively used in the application layer. The middleware layer manages hardware such as an RFID reader or a label printer. Finally, the application layer uses the transmitted tag data to meet specific goals, such as enterprise resource planning (ERP), supply chain management (SCM), and customer relationship management (CRM). It performs the function that actually applies.

On the other hand, in order to connect with an application by applying RFID in the enterprise, the client program (software) provided by the RFID reader equipment company is installed and connected to the corresponding software to control the state of the RFID reader. The manager accesses and controls the reader using each program provided by the equipment company. For example, as shown in FIG. 1, when a client program provided by a first device company is written in JAVA, a client program written in Java should be used to use a device provided by the first device company. . Similarly, when the client program provided by the second equipment company uses the web user interface (UI), the web UI should be used to use the device provided by the second equipment company, and the client provided by the third equipment company. If the program is written in Visual Basic, the client program written in Visual Basic must be used in order to use the device provided by the third party equipment company.

However, the software provided by each equipment company has a different program environment, interface, reader control command, etc. Therefore, the user has to use a device provided by one company.

In addition, even when the device needs to be upgraded or replaced, it is inconvenient to use a device provided by another company and use only a device of a specific company. If a user wants to use a device provided by another company, he / she should learn how to use software provided by another company, and it is difficult to control each device because the compatibility between devices provided by different companies is difficult. The following problems arise.

Therefore, there is still a need for an RFID management system or method that can integrate and control different types of RFID devices provided by different companies, and in particular, a programming language (eg, JAVA, Visual) that processes identification codes. Regardless of standardization, there is a need for an RFID management system or method that can provide a convenient and consistent interface to users or administrators regardless of the standard.

The present invention was devised to solve the above problems of the prior art, and an object of the present invention is to provide an RFID management system and method that can provide a consistent interface to different types of readers.

It is another object of the present invention to provide an RFID management system and method capable of remotely controlling whether readers are operated, antenna status, number of antennas, output strength, and the like.

Still another object of the present invention is to provide an RFID management system and method capable of monitoring tag data transmitted from each reader and filtering tag data by applying a specific condition.

To this end, the RFID management system according to the present invention, the first reader adapter unit for converting the data of the first message format transmitted from the first reader into the data of the third message format, and the first transmission from the second reader A reader adapter for converting data in a second message format into data in a third message format, the reader adapter controlling the first and second readers through the first and second reader adapters, and the third message. An RFID control device including a core engine for collecting and filtering data converted into a format, and an application adapter for providing an interface for transmitting data transmitted from the core engine to an external application; And an RFID management device interworking with the RFID control device and providing a user interface for controlling the first and second readers.

The RFID management apparatus according to the present invention manages reader information for readers of different models controlled by different client programs, and manages readers of the different models through the same interface based on the reader information. Leader management means for controlling; Data source management means for defining a data source by separating and / or grouping the reader and one or more antennas provided in the reader, respectively; Filter control means for managing filtering conditions for the data source; And user management means for registering, modifying and deleting a user of the RFID management apparatus and managing access rights of individual users.

On the other hand, an RFID management method of one embodiment of the present invention includes the steps of: a) registering reader information and model information including respective message formats to a reader; b) receiving and outputting status information about the reader; And c) controlling the reader based on the registered leader information and model information according to the input control information.

The RFID management method according to another aspect of the present invention includes the steps of: a) registering reader information and model information including respective message formats with a reader; b) defining a data source by separating and / or grouping the reader and antennas provided in the reader; c) extracting and displaying the reader information included in the data source when the control request of the specific data source exists; And d) controlling a reader and an antenna corresponding to the data source based on the registered reader information and model information according to the input control information.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments. For reference, in the following description, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention are omitted.

2 is a diagram showing the structure of an RFID management system according to the present invention. The RFID management system according to the present invention may be largely divided into an RFID control apparatus 200 and an RFID management apparatus 300. The RFID control apparatus 200 collects, filters, and transmits tag data transmitted from each reader 110, 120, and 130 to the application 500, and the RFID management apparatus 300 interfaces to a user. It provides a user interface (UI) and interoperates with the RFID control apparatus 200 to perform reader control, data source management, and filter management.

Hereinafter, an RFID management system and method according to a preferred embodiment of the present invention in detail with respect to an RFID tag, an RFID reader, and an application will be described in detail.

The RFID tag 100 is attached or provided to an object requiring identification of a person, a vehicle, a product, a traffic card, and the like, and stores detailed information (tag data) of the object. RFID tags can be classified into three types according to their read / write capabilities: read only tags, write once read many tags, and read / write tags. Since it is programmed from the above, it is impossible to change the information. WORM tag allows the user to program the data, but not after that. The read / write tag is a structure that can change the program or data again and again.

The RFID readers 110, 120, and 130 perform a function of recognizing and transmitting the tag 100 existing in the reader recognition space to the RFID control apparatus 200. The RFID reader includes one or more antennas to receive information transmitted from the RFID tag. If the RFID reader includes a plurality of antennas, each antenna individually receives tag information and transmits it to the RFID control apparatus 200. Can be implemented. Meanwhile, each RFID reader transmits tag data to the RFID control apparatus 200 using a different message format or protocol according to the reader manufacturer (equipment manufacturer) or model. In FIG. 2, a first reader (eg, Alien Reader) 110 having four antennas 111, 112, 113, and 114 is connected to the first reader adapter portion 211 of the RFID control device 200. The second reader (eg, Matrics Reader) 120 having two antennas 121 and 122 is connected to the second reader adapter 212 of the RFID control apparatus 200, and one antenna 131. The third reader (for example, Intermec Reader) 130 having the () is connected to the third reader adapter unit 213 of the RFID control device 200 to transmit tag data of different message types to the corresponding reader adapter unit. Shows that.

The RFID control apparatus 200 according to the preferred embodiment of the present invention is largely composed of a reader adapter 210, a core engine 220, and an application adapter 230.

The reader adapter 210 includes a reader adapter unit corresponding to each reader in order to receive tag data from heterogeneous readers. In FIG. 2, first, second, and third reader adapters corresponding to three different types of first, second, and third readers 110, 120, and 130, respectively, using different message types (protocols). The parts 211, 212, 213 are shown. In detail, the first reader adapter converts data (tag data) of the first message format transmitted from the first reader into data of the third message format. Similarly, the second reader adapter converts the data in the second message format sent from the second reader to the data in the third message format. Here, the third message format is a message format for integrating different message formats used by heterogeneous readers into one, which may be one of the message formats already used (for example, used by the third reader). The message format is defined by the RFID International Standards Organization. Meanwhile, the reader adapter may further include a reader adapter unit related to standardization, for example, a reader adapter unit for an EPC (Electronic Product Code) for further expansion, in addition to the reader adapter unit for the readers currently used. A fourth reader adapter 214 is shown. The reader adapter is interlocked with the reader managing means 310 of the RFID management apparatus 300 to be described later, and controlled by the reader managing means from the user, so that the user can remotely control the RFID reader. On the other hand, the tag data received from each reader adapter unit 211, 212, 213 is transmitted to the core engine 220.

The core engine 220 performs a function of collecting and filtering tag data. The core engine includes a data collector 221 for collecting tag data received through one or more readers, and a filtering unit 222 for extracting data corresponding to a condition desired by a user from the collected data. In addition, when the amount of data is large, in order to reduce the data throughput of the filtering unit, it may be implemented to include a pre-filtering unit 223 for extracting only a specific product or removing redundant tag data in advance.

The application adapter 230 provides an external service call unit 231 for passing the filtered result to an external service server defined in the filter condition, and an API for allowing the application to control the reader or reporting the result to the application. It consists of an Application Programming Interface unit 232.

The above-described RFID control apparatus may be implemented in the form of a server, and in this case, components such as the reader adapter, the core engine, and the application adapter may be implemented in the form of hardware or middleware.

On the other hand, the above-described RFID control device 200 is interlocked with the RFID management device 300, the RFID management device 300 allows a user or administrator to control the RFID control device 200 in a web environment or remotely Provide an interface. In addition, an EPC network 400 such as an ONS (Object Name Service) server that provides location information of a PML server, and a Physical Markup Language (PML) server that stores and manages static information of objects and historical information recognized through RFID technology. ) Can be linked with the component.

RFID management apparatus 300 according to a preferred embodiment of the present invention is largely composed of a reader management means 310, data source management means 320, filter management means 330, the user management means 340.

The leader management unit 310 performs a function of managing functions provided by equipment companies, such as operation control and status monitoring, for heterogeneous readers using the same interface. The leader management unit 310 may be subdivided into a model manager 311, a leader manager 312, and a leader operator 313.

The model manager 311 registers, modifies, deletes, and outputs detailed model information such as class, model number, manufacturer, maximum output, and number of antennas for each reader. Referring to FIG. 4A, the model manager first displays a model name input screen when there is a request for registering model information from a user (S411). Then, it is checked whether the corresponding model is registered based on the reader model name input by the user (S412). If model information corresponding to the input model name is not registered in the database, the model manager displays a model information registration screen (see FIG. 8) (S413). When the user registers detailed model information of the leader (S414), newly registered model information is displayed (S415) (see FIG. 9). On the contrary, if the corresponding model information is registered in the database, the model manager displays the registered model information (see FIG. 9). On the other hand, such a model registration process may also be performed at the request of the leader management unit 312, if the model information for the leader to be registered in the leader management unit is not registered in the database 350, the leader management unit to the model management unit Upon requesting registration, the model manager checks whether the corresponding model is registered based on the input information and registers detailed model information.

The process of modifying or deleting model information is performed by displaying a model information modification screen or a model information deletion screen when a user requests for model information modification or deletion, and corrects or deletes model information according to information input from the user. . Finally, the process of outputting the model information is a process of displaying or printing the model information so that the user can recognize the model information.

The reader manager 312 may include a reader name (reader name), model name, network setting information (reader IP address, reader port number, gateway address, netmask address, DNS address, host IP address, host port number, etc.). Performs a function to register, modify, delete, and print detailed reader information. Referring to FIG. 4B, the reader manager first displays a reader name input screen when there is a reader information registration request from the user (S421). Then, it is checked whether the leader is registered based on the reader name input by the user (S422). If the leader information corresponding to the input leader name is not registered in the database, the reader manager displays the leader information registration screen (see FIG. 10) (S423). When the user registers detailed leader information of the leader (S424), it is inquired whether model information of the newly registered leader is registered in the database (S425). In this case, if the model information of the leader is not registered, the leader manager requests model registration from the model manager and the above-described model registration process is performed (S426). When the model registration process is completed or the model information of the leader is registered from the beginning, the leader management unit displays the registered leader information (S427) (see FIG. 11). On the other hand, if the reader information corresponding to the input reader name is already registered in the database, it is inquired whether to terminate the leader information registration, modifying or deleting the reader information, and performs the corresponding function according to the information input by the user.

The process of modifying or deleting the leader information is similar to the process of modifying or deleting the above-described model information, and displays a reader information modification screen or a reader information deletion screen when a reader information correction or deletion request is made from the user, and is input from the user. This is done by modifying or deleting the leader information according to the information. In addition, the process of outputting the reader information displays or prints the reader so that the user can recognize the reader information.

The reader operating unit 313 controls the on / off status of the reader, the output strength of the radio wave, the function of changing the order of the antennas when a tag is read, and when and how many times the tag data has been read by a specific reader. Performs overall control of the reader, including monitoring functions. Referring to FIG. 4C, the reader operating unit first displays a reader control screen (see FIG. 12) when there is a request for status information of the reader from the user (S431). Then, the information of the reader registered in the database is extracted according to the reader information (eg, the reader name) input from the user (S432), and the reader adapter of the RFID control device is requested to the status information on the reader to be controlled by the user ( S433). The reader adapter checks the status of the reader through the reader adapter corresponding to the reader, and transmits the status information of the reader to the reader operator. The reader operating unit displays this (S434), and controls the reader according to the control information input from the user. For example, when a user requests a state change of a specific reader (S435), the reader operator transmits the state change request information on the corresponding reader, which is divided by company or model, to the reader adapter of the RFID control device (S436). The reader adapter unit corresponding to the corresponding reader is controlled to change the state of the reader (S437). The reader adapter transmits the result to the reader operating unit, and the reader operating unit outputs state information about the reader (S438). For reference, FIG. 18 illustrates a part of a program for turning on / off the reader state in the leader operating unit of the leader management unit.

In addition, the function of controlling the output strength of radio waves, changing the order of antennas when a tag is read, and monitoring of which tag data has been read by a particular reader at any time and similar to the above-described state control (change) It can be performed as.

The data source management unit 320 performs a function of separating or grouping each reader and antenna according to a purpose and purpose. In the present invention, such logically divided or grouped units are defined as datasources. In addition, the data source management unit 320 according to the present invention may be subdivided into a data source management unit 321, a data source operation unit 322, and a log information unit 323.

The data source manager 321 separates and / or groups each reader and antenna to define a data source. For example, if the first and second antennas 111 and 112 of the first reader 110 and the first antenna 121 of the second reader 120 are connected to the inventory management shelf, The first and second antennas 111 and 112 and the first antenna 121 of the second reader 120 may be defined as one data source. The data source management unit displays the reader and antenna information registered in the reader management means on the screen, and the user can know which reader and antenna are configured as the data source. On the other hand, the data source defined in the data source management unit may be used as a filter application unit to be used in the filter management means to be described later. 5A illustrates a process of registering a data source in the data source manager. First, the data source manager displays a data source registration screen (see FIG. 13) (S511). Then, the list of readers not included in the registered data source is searched (S512). If a reader that is not included in the data source exists (S513), data source information registration is requested, and when the corresponding reader is registered as the data source (S514), the registered data source information is displayed (S515). On the other hand, if there is no reader included in the data source, the data source registration process is terminated.

The data source operator 322 performs a function of monitoring tag data (eg, tag ID, read time, location, etc.) read through the respective data sources. In addition, the data source operator can send commands collectively to readers or antennas grouped by data source. 5B illustrates a process of changing a state of a specific reader in the data source operator. First, the data source operator displays a data source control screen (see FIG. 14) (S521). In operation S522, the data source information list is retrieved and displayed according to a user's request. If there is a request for controlling a specific data source (eg, changing the state of the reader) from the user (S523), the data source operation unit extracts and displays the reader information included in the corresponding data source (S524). In addition, when a state change request of a specific reader is requested from the user, the data source operation unit requests a state change of the corresponding reader to the RFID control apparatus (S526), and the corresponding reader adapter unit changes the state of the reader to change the state from the RFID control apparatus. When the completion signal is transmitted (S527), the data source information is output (S528).

The log information unit 323 records the results of the tag data filtered through the data source in the form of a file or the like in a database or storage means and displays the recorded details. 5C illustrates a process of outputting log information corresponding to a specific data source in the log information unit. The log information unit first displays a data source selection screen (S531), and when selection information of a specific data source is input by a user (S532), retrieves log information of the corresponding data source (S533), and outputs log information (S5313). S534).

The filter manager 320 performs a function of managing filtering, logging, etc. of data sources defined through the data source manager. The filter managing unit 320 may be divided into a product filter unit 321 and a condition filter unit 322.

The product filter unit 321 provides a function of registering and managing conditions so that a specific reader processes only a specific product code. For example, when a plurality of readers are installed in each plant for each process or product, the product code value may be registered in advance, and the reader may control to process only a specific product code. 6A illustrates a process of registering a filtering condition for a specific product in the product filter unit. First, the product filter unit displays a product filter registration screen (see FIG. 15) (S611). When a product filter condition is input by a user (S612), the product filter unit selects a code of a product to be filtered (S613). The product filter information is registered, and the registered product filter information is output (S614).

The condition filter unit 322 provides a function of registering and managing specific conditions to be filtered. The condition filter part is mainly used to give more specific conditions in the process after the product filtering is performed. The user may assign a condition only to a specific antenna of a specific reader through the condition filter unit or condition to process only tag data read at a specific time. 6B illustrates a process of registering a filtering condition for a specific reader and / or a specific antenna in the condition filter unit. First, the condition filter unit displays the condition filter registration screen (see FIG. 16) (S621). When a data source to which the filtering condition is to be added is selected by the user (S622), the condition filter unit requests to input a specific condition. Then, the user inputs specific filtering conditions such as a filter target item, an operator, a filter value (S623), and the condition filter unit determines whether the input filtering conditions are matched (validity) (S624). If the condition is not matched (not valid), the condition filter unit requests re-entry of the filtering condition, and if the condition is matched (if appropriate), registers the condition filter information and outputs the registered condition filter information ( S625). For reference, FIG. 19 is an excerpt of a program for registering filtering conditions in the condition filter unit of the filter management means.

The user managing means 340 performs a function of managing a user of the RFID managing apparatus 300. This may be divided into a user searcher 341 and a user manager 342.

The user search unit 341 provides a function for searching a list of currently registered users. As shown in FIG. 7A, the user search unit displays a user search screen (S711), searches for user information in a database based on information input from the outside (user, administrator, etc.) (S712), and outputs a searched user list. To perform the function (S713).

The user manager 342 manages (controls) the reader and the RFID control device or manages user information to be used. That is, the user manages the reader management means, data source management means, filter management means, registers, modifies, deletes users, and grants access rights. 7B illustrates a process of performing user registration in the user manager. Referring to FIG. 7B, the user manager displays a user registration screen (see FIG. 17) (S721), and when a user ID is input (S722), the user manager determines whether a user ID exists by searching a list of users stored in a database (S722). S723). As a result of the determination, if the user ID does not exist, the user ID is requested to be re-entered, and if the user ID exists, the user information input is required. When the user information is input (S724), the user manager displays the newly registered user information (S725), thereby completing the user registration process.

Meanwhile, the database 350 used in the present invention may be provided in the RFID management apparatus or the RFID control apparatus, and may also be implemented as an external database as shown in FIG. 2. The database 350 stores model information, reader information, data source information, user information, and the like, and the information is implemented to be integrated and stored in a single database, or the model information database, reader information database, data source information database, It may be implemented to be stored separately in a separate database such as a user information database.

Finally, the application 500 applies the transmitted tag data to actual tasks such as enterprise resource planning (ERP), supply chain management (SCM), and customer relationship management (CRM).
