The present invention relates to an electronic tag information processing apparatus and method thereof based on a wireless internet platform including a mobile communication terminal. More particularly, the present invention relates to an electronic tag (hereinafter referred to as "RFID") technology. And an electronic tag reader (hereinafter referred to as an "RFID reader") capable of reading information "referred to as an RFID tag" in a non-contact manner, using a mobile communication terminal equipped with the RFID reader. The present invention relates to a wireless internet platform-based electronic tag information processing apparatus and method for processing RFID tag information at a software platform level in order for a user to acquire and utilize information of an RFID tag attached to an object anytime and anywhere.

Conventionally, by attaching a barcode to a number of objects, such as various goods, facilities, inventory, etc. to obtain information about the information and price of each object, various application development has been made by using this. However, in order to improve the limitations of barcode technology (for example, it requires human intervention for barcode recognition), the use of RFID technology, which is regarded as an alternative to barcodes, is actively coming to the fore. It is considered to be an essential technology to advance.

RFID technology utilizing RFID tags collects and records tag information from RFID tags attached to objects using radio frequency, and uses automated tag recognition and collection (AIDC: Automatic Identification and Data Capturing). It is classified as one of the techniques.

The RFID system consists of three main components: a hardware device such as an RFID tag and an RFID reader, and a host computer that receives and processes tag data by connecting to an RFID reader. The RFID reader reads data from the RFID tag and wires the data. It is a method of transmitting to a host computer through a wireless communication network.

In general, in order to utilize RFID technology, RFID tag is assigned a kind of code value to identify the object to which the tag is attached, and the RFID reader periodically collects the code value in the individual tag existing in the RFID reader recognition area. In other words, this task is performed at least ten times per second. Each time the recognized electronic tag information is transmitted to the host computer. As code information of an individual RFID tag is transmitted to the host computer several times per second for a plurality of tags existing in the recognition zone, duplicate information is removed from a large amount of electronic tag information, which is to be utilized. There is a need for a function that refines and delivers only the information needed for an application.

Therefore, in the RFID technology using the above RFID tag, the RFID tag must have a separate RFID reader and a host computer for refining and processing the tag information to recognize and use the information of the electronic tag.

Third, in order to avoid the above-mentioned problems, it is necessary to adjust the inflow of the appropriate data through the processing in the mobile terminal. The terminal application application developers utilizing the RFID reader attached to the mobile terminal are required to apply each time in developing the application. As mentioned above, in the development of the program, it is necessary to repeatedly perform the task of selecting and refining a large amount of duplicate data, which increases the effort and time required for developing the application.

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

1 is a block diagram of an embodiment of an RFID tag information processing apparatus based on a wireless Internet platform according to the present invention.

As shown in FIG. 1, an RFID information processing apparatus based on a wireless Internet platform according to the present invention includes an electronic tag reading device (RFID reader) 110 for recognizing code information recorded on an RFID tag, and reading the electronic tag. Wireless internet platform 120, which is a software operating platform for operating and controlling the terminal hardware including the device (RFID reader) 110 and is responsible for purifying the electronic tag information collected from the RFID reader in terms of RFID, and the electronic tag information. It includes a terminal / RFID application for providing a variety of services to the terminal user 130.

The wireless Internet platform 120 is again at a low level to maintain independence from the terminal basic software layer 121, which serves as a kind of device driver for controlling the hardware including the RFID reader 110, and the specific terminal hardware and manufacturers Based on the development of the terminal software abstraction layer 122, which is a layer that defines most functions necessary internally in the terminal such as system event definition and terminal hardware control that can occur in the terminal, and application programs using basic terminal applications and electronic tag information. Application API layer 124, which is a layer that defines and provides an application interface (hereinafter referred to as "API"), and basic functions provided by the terminal software abstraction layer 122. Program to satisfy various functions defined in It includes a wireless Internet platform software engine (123).

In more detail, the wireless internet platform 120 of the electronic tag information processing apparatus based on the wireless internet platform has a basic principle of extending the wireless internet platform operating on the mobile terminal, and the RFID reader 110 for the mobile terminal. The terminal basic software 121 and the terminal software abstraction layer 122 and the functions provided by the terminal software abstraction layer 122 to control the information at a low level. The wireless Internet platform engine 123, which is responsible for collecting / purifying the electronic tag information transmitted from the reader 110, and eliminates the repetitive work of refining / processing duplicate and unnecessary electronic tag information in the terminal application implementation. Provides an effective development environment for developing application programs using individually recognized electronic tag information It consists of an application API layer 124 with various APIs, which maintains the hierarchical structure provided by the wireless Internet platform 120, and controls the RFID reader and the electronic tag information according to the role of each layer. It is characterized in that the additional function is given to each layer to be utilized by the terminal application program by collecting / refining.

Meanwhile, the terminal basic software 121 layer and the terminal software abstraction layer 122 may be regarded as the same layer according to a platform and a situation such as a terminal / platform manufacturer.

The wireless internet platform engine 123 collects and refines RFID tag information present in the RFID reader recognition area based on a function defined for controlling the RFID reader provided by the terminal software abstraction layer 122 to apply the application API layer 124. It is responsible for processing and processing information in a form that conforms to the API requirements defined in).

In addition, in the application API layer 124, the terminal RFID application 130 is duplicated and used by the application developer so that the application can effectively acquire and use the electronic tag information without worrying about refining the unnecessary electronic tag information. Define and provide an easy API.

2 to 9 illustrate roles, functions, and operations to be provided in each layer of the wireless Internet platform 120.

Each figure shows a series of flows in which the terminal application acquires electronic tag information from the RFID reader 110 through a function provided by the wireless internet platform 120, and thus, each layer 121 to 124 of the wireless internet platform 120. It shows about the role.

In the present invention, a method of obtaining electronic tag information from a terminal application program is divided into two methods.

First, a request / response model scheme (FIG. 2) responding to the request in the wireless Internet platform 120 in response to a one-time (one-time) request of the terminal application and the terminal application provide a kind of event listener. Delegation event processing to deliver the electronic tag information collected to the application through the event listener when a specific event occurs by registering to the 120 and at the same time delivers the event notification conditions defined by the application to the wireless Internet platform 120 Model) method (Fig. 7).

FIG. 2 is a flowchart illustrating an electronic tag information processing method based on a wireless internet platform according to the present invention, and illustrates a process of an application program based on a request / response model obtaining electronic tag information from a wireless internet platform.

First, FIG. 2 is a request / response method, which is a first method of obtaining electronic tag information from a terminal application program, and the wireless Internet platform waits for a request from the terminal application program (210). In this case, the driving of the RFID reader may be started with the driving of the application program to be used or may be driven by the user. For this purpose, the API for supporting the RFID reader is supported in the application API layer.

Thereafter, the terminal application requests the information on the electronic tag to the wireless Internet platform (220). The information request method can be divided into two types.

First, a method of calling an API of an application API layer that provides a corresponding function to a function for obtaining a list of electronic tags provided by the terminal basic software 121 or the terminal software abstraction layer 122 for an RFID reader. Second, the application program can be divided into a method of acquiring a tag list in a wireless Internet platform until a request for acquiring a tag list is given a response completion condition for the request and satisfies the condition.

As the response completion condition, conditions such as a certain time interval, an end request from an application program, and a specific tag ID or a tag code pattern are satisfied, and generally, the electronic constant time interval is generally used.

When a certain time interval is used as a response completion condition, tag information is collected for a given period of time from the time when the application makes a request, duplicated information is removed, and a list of recognized tag information is delivered to the application. In case of the termination request from the second application, the tag information collection termination request is explicitly delivered by the application, and the last method is the tag information recognized from the RFID reader by giving a specific tag ID or tag code pattern. This is a method of responding to an application program call when a given code ID or code pattern is satisfied. In the third case, since the application waits until a specific pattern is matched, the first method, that is, given a certain period, meets the first condition among the pattern matching condition and the period completion condition. The case is transformed and used in such a way that it becomes a response completion condition. In general, the tag list is generally collected electronically, that is, for a given time.

In the request / response method, when the terminal application program wants to call the electronic tag information, it may additionally set a confirmation recognition condition and a filtering condition in addition to the response completion condition.

The definite recognition condition is that not all tags existing in the recognition area are recognized when the RFID reader periodically reads the tag due to the characteristics of RFID, or tag information outside the recognition area is detected by the RFID reader by external factors. It refers to a condition for considering only the tag information satisfying this as a standard to be generated as an electronic tag existing in the recognition region of the RFID reader. Determination conditions for this may include a case where a certain number of times is recognized based on the first tag recognition and a case where a certain time is recognized based on the first tag recognition time, and the like. In both cases, this tag is considered unrecognized if there is a certain timeout, and if any one tag does not currently meet the confirmed recognition conditions and no additional recognition has been made during the timeout from the last recognition. . This is not required to be input from the application. Basically, the first one-time recognition of the tag during the collection period is regarded as confirmation. In other words, if a particular electronic tag is recognized at least once, it means that the tag is regarded as satisfying the predetermined recognition condition. This confirmation condition is a basic filtering function that removes duplicate data for one electronic tag. In addition, the filtering condition mentioned above is included in the final list by applying a specific tag ID list or tag code pattern list as a criterion for selecting a tag list matching the filtering condition from the electronic tag list collected during the collection period. It is used as a basis for deciding whether or not to exclude it from the final list.

In summary, in general, an RFID reader attached to a terminal recognizes one or a plurality of electronic tag information existing in a recognition region of the reader, and the information about this is repeatedly transmitted to the wireless internet platform during the collection period. . Accordingly, the terminal application sets the predetermined recognition condition and the filtering condition. If there is no setting, the terminal application program refers to the default setting value. The electronic tag information that has been repeatedly transmitted for each of the electronic tags is taken based on the definite recognition criteria, and only one electronic tag information that meets the criteria for each tag is managed through a kind of tag list. For an electronic tag that exists in the tag list and meets the definitive recognition conditions, this information is ignored if it is passed back from the RFID reader. That is, filtering of duplicated information is performed. This operation is performed until the response completion condition is reached. The wireless internet platform engine manages the electronic tag information recognized from the RFID reader as a series of lists from each request until the response completion condition is reached. The first recognition time, the latest recognition time, and the number of recognition times of each tag are recorded / managed for the electronic tag information, which is a component, to determine whether it meets the above-mentioned confirmation recognition condition. Then, only the electronic tag list satisfying the definite recognition condition among the electronic tag information in the list is selected and delivered to the application program.

Prior to delivering the tag list to the application, if a filtering condition is given from the application, the filtering condition determines which electronic tag information of the tag list should be delivered to the application.

The filtering condition is information that is set by the application and specifies a condition for selecting a list of tags to be finally delivered in response. As mentioned above, a specific tag ID list is given to an electronic tag. Include in the final list the case where one or more of the tag patterns are the same as, or if any of them are satisfied, and if a specific tag ID list or one or more tag patterns are given and any one of them matches, This means specifying the conditions to be excluded from the list.

Therefore, the wireless internet platform engine performs filtering to apply the filtering condition for each tag of the tag list and to exclude it from the final list before delivering it to the application. The final tag list is passed to the application.

Confirmation recognition conditions and filtering conditions including the response completion condition described above are not essential elements but are optional elements depending on the requirements of the application program.

As described above, the wireless Internet platform engine that receives the execution request 220 through the API for collecting tag information of the API layer from the terminal application analyzes initialization information such as response completion condition, confirmation recognition condition, filtering condition, etc., which are transmitted upon request. (230). As mentioned above, the above conditions are not mandatory, and they are handled by using the default settings unless the application program has set them.

After the analysis is completed, the wireless internet platform engine uses the functions provided by the terminal software abstraction layer to display the electronics within the recognition domain from the RFID reader until the response completion condition (mainly a given period of time from the request time) is reached. Collect tag information (240). In this case, information about a plurality of electronic tags existing in the recognition region is collected from the RFID reader once or a plurality of times for a predetermined time. That is, in the wireless Internet platform engine, duplicate tag information for each tag is transmitted to a plurality of electronic tags existing in the reader recognition area, whereas an application program requires only one piece of identification information for each tag. When the program requests a list, only one tag information suitable for the tag is selected for each tag based on the confirmed recognition condition delivered at the request, and the remaining duplicate information is removed. It also removes tag information that does not meet the conditions.

When the response completion condition is reached, the wireless internet platform engine performs a selection operation on the tag list suitable for the condition from the collected tag information list based on the filtering condition delivered in the application request (250), and sends the result to the application. (260).

3 is a view illustrating an embodiment of a request / response method of an electronic tag information processing method based on a wireless internet platform according to the present invention. Represents the process of acquiring and continuing to acquire information through repetitive calls.

First, the terminal application program requests the tag information collection to the wireless Internet platform together with initialization values such as response completion condition, confirmation recognition condition, and filtering condition (310).

As mentioned above, the above conditions are optional elements by the application program, and if no values are given, the predefined default values are used.

The wireless Internet platform engine requests tag information from the RFID reader during the collection period until the response completion condition is reached, collects and refines it (320).

After the collection is completed, the wireless Internet platform engine delivers the collected tag list to the application in response to the call (330). At this time, if a filtering condition is given, the tag list suitable for the condition is selected and delivered to the application program. An application can call APIs that perform the above flow, either continuously or repeatedly. Lastly, as already mentioned above, the application program provides an application API corresponding to the function provided by the terminal software abstraction layer that simply provides a tag list collection function through the tag information requesting process 310 and the collecting and refining process 320. It can be replaced by API calls in the layer. This is entirely up to the application developer.

FIG. 4 is a diagram illustrating another embodiment of a request / response method of an electronic tag information processing method based on a wireless internet platform according to the present invention, wherein an application program session-based electronic tag information from a wireless internet platform based on a request / response model. It shows the process of obtaining repeatedly.

4 illustrates the concept of sessions, and sets initializing information such as response completion condition, confirmation recognition condition, and filtering condition once at the time of opening the session, and all tag list requests until the end of the session after the session is opened. The setting value of is to be applied as it is.

The application opens a session, sets initialization information, and receives a sort of session ID (410).

When the application program requests tag information together with the session ID when necessary, the wireless Internet platform engine refers to the initialization information corresponding to the session ID, and tags from the RFID reader using the function provided by the terminal software abstraction layer during the collection period. The function receiving the information is repeatedly called once or more times to collect the electronic tag information (430), and the collection result is delivered in response to the request of the application. For example, if the response completion condition is 1 minute, when the application requests the electronic tag information with the session ID, the tag list is collected for 1 minute based on the initialization information corresponding to the session ID, and the result is sent to the last request. This means that the application will wait for 1 minute after the tag list call arrives. At this time, if the filtering condition is given, the tag list suitable for the condition is selected and delivered to the application program. Also in this case, as in the case of FIG. 3, the application program may repeatedly call an API supporting the above flow.

Thereafter, the application terminates the session (440).

In addition, the application program may change initialization information about the session through the API provided by the application API layer while the session is maintained (450).

FIG. 5 is a flowchart of another embodiment of a request / response method of an electronic tag information processing method based on a wireless Internet platform according to the present invention, wherein an application program based on a request / response model acquires electronic tag information from a wireless internet platform. In the process, the application program executes the collection start command and the collection stop command of the electronic tag information to obtain the information collection result for two time points.

FIG. 5 is a flow chart related thereto, wherein the terminal application program first requests that the wireless Internet platform start acquiring electronic tag information existing in the RFID reader recognition region using an API provided by an application API layer (510). In this case, the above-mentioned determination recognition condition, filtering condition and the like may be transmitted.

The wireless internet platform analyzes the initialization conditions received upon request (520), and based on this, the wireless internet platform engine collects electronic tag information existing in the cognitive area of the reader by using a function provided by the terminal software abstraction layer. For example, recognition of individual tags and elimination of duplicate data are based on the determined recognition conditions (530).

Thereafter, when the terminal application requests completion of information collection (540), the wireless Internet platform engine terminates the above information collection, and if filtering conditions exist, selects the electronic tag list to be finally delivered from the electronic tag list (550). In step 560, the terminal responds to the result.

FIG. 6 is a view illustrating another embodiment of a request / response method of an electronic tag information processing method based on a wireless internet platform according to the present invention. In the acquisition, the start and end instructions for collecting the electronic tag information are executed by the application program and the tag information is collected for two time points.

When the terminal application requests the collection of the electronic tag information to the wireless internet platform (610), the wireless internet platform engine continuously collects the electronic tag information existing in the RFID reader until receiving the collection termination request (620). . In this case, whether to regard the tag recognition is based on the confirmation recognition condition, and duplicate data for each tag is also removed based on the confirmation recognition condition.

When the terminal application requests the end of the electronic tag list collection (for example, when the terminal user presses a specific button to request the collection termination), the wireless Internet platform engine terminates the information collection and reflects the filtering conditions. After the electronic tag information required by the program is selected, the result is transmitted to the application program (630).

7 is a flowchart illustrating a delegation event processing method of an electronic tag information processing method based on a wireless internet platform according to the present invention, wherein an application program acquires electronic tag information from a wireless internet platform based on a delegation event processing method; Indicate the process.

First, the terminal application registers an RFID tag information event listener that satisfies the format proposed by the wireless Internet platform through the API provided by the application API layer.

Event listener is a subject that receives and processes electronic tag information collected / refined from wireless internet platform engine. In addition, the wireless Internet platform engine collects the electronic tag information and sets an event notification condition describing various conditions for delivering to the application program through the event listener.

The event notification condition includes the "event notification period" which is the minimum period for delivering the electronic tag information collected through the event listener, the filtering condition to be applied to each event notification period, and the completion condition of the entire event notification.

The event notification cycle includes the start and end conditions of the cycle.The start condition includes the start request from the application program, the end of the last event notification cycle, or the time when the first tag is recognized after the end of the previous event notification cycle. This can be The end condition of the cycle may include a time point elapsed from the beginning of the cycle, a time point when one of a specific tag ID or a tag code pattern list is satisfied, an explicit end call by an external application program, and the like.

At the end of each event notification cycle, the WIP engine delivers the tag list collected through the registered event listeners.

The filtering condition is applied to select only the tag list satisfying the given condition among the tag list collected during the event notification cycle.

The complete event notification completion condition refers to a condition for stopping tag information notification to an application program, which is a certain time (which must be at least longer than the “event notification cycle”) or the number of event notification cycles performed (at least once). And so on. This is not set by default. That is, when receiving a request for completion of event notification from an application program, the tag information collection work is stopped.

In addition, an initialization value to be commonly applied to every event notification, for example, the above-described confirmation recognition condition, is set (710).

After the initialization operation as described above, the application program requests to start tag information collection (720).

The wireless internet platform engine collects the electronic tag information existing in the recognition region of the RFID reader during the event notification period set in the determination process setting step 710 (step 730). In this case, only one piece of tag information satisfying the condition is selected for each tag based on the determined recognition condition, and the remaining duplicated information is removed.

If one event notification period is ended, a tag list necessary for delivery to an application is selected by applying the filtering condition set in the determined recognition condition setting process 710 of the collected tag list (740).

The wireless internet platform engine then delivers the final tag list via the registered event listener (750).

Finally, if it is determined that the event notification completion condition has not been reached, the next event notification cycle is started (760). However, when the event notification completion condition is not given, or even if the completion step is not reached even if the given event is delivered from the application to the wireless Internet engine, the notification is applied first to terminate the notification.

FIG. 8 is a diagram illustrating an embodiment of a delegate event processing method of an electronic tag information processing method based on a wireless internet platform according to the present invention, wherein an application program acquires electronic tag information from a wireless internet platform based on a delegate event processing method The process of doing so.

Initialization information including event notification conditions such as an event listener 810, an event notification cycle, a filtering condition, a notification completion condition, and the like are set through the initialization process along with the application program 820.

When the terminal application requests to start the tag list notification (830), based on the value set in the step 820 of setting the initialization information, tag collection starts at the end of every event notification cycle (830), and within the period The collected tag list is delivered (840) and delivered to the application through an event listener (850).

In the tag list transfer process 840 collected in the period, in order to generate the electronic tag list, whether or not the electronic tag is recognized based on the determined recognition condition and duplicate data is removed. In addition, as mentioned above, if there is a filtering condition, the wireless internet platform engine selects a tag list necessary for delivery immediately before delivering to an application program through an event listener at the end of the event notification cycle.

The application may request to suspend notification 870 and restart 880 depending on the situation. In this case, it may be determined whether the tag information collected during the pause 870 is transmitted to the application program for the ongoing event notification period (860).

Finally, when the application program no longer wants to collect tag information, the tag collection notification completion request is requested (890). For reference, the tag collection notification completion request may be replaced with the first event cycle completion condition. That is, the entire process may be terminated by performing one cycle instead of repeatedly performing the event notification cycle as in the embodiment, and the application may be changed in such a manner as to repeat the entire process.

9 is a diagram illustrating another embodiment of a delegation event processing method of an electronic tag information processing method based on a wireless internet platform according to the present invention, wherein an application program acquires electronic tag information from a wireless internet platform based on a delegation event processing method; The process of doing so.

The difference between FIG. 9 and FIG. 8 is in the manner of completing the tag list notification.

In the case of FIG. 9, whether the event notification completion condition, which is one of the initial value settings, is satisfied is transmitted 910 with the electronic tag information at the end of each event notification cycle, the application program may determine whether the notification is completed. Of course, even if the notification is not completed, the wireless Internet platform stops collecting the electronic tag information when the application requests completion of the tag collection notification.

In summary, the tag data collected from the RFID reader attached to the mobile terminal repeatedly recognizes one or a plurality of tag information existing in the reader recognition area at a rapid cycle.
