1 is a block diagram illustrating an event cycle tag data processing system of a wireless identification middleware according to an embodiment of the present invention.

The tag data processing system of the illustrated wireless identification middleware primarily collects wireless identification tag data recognized through the wireless identification tag reader through the collection unit 100, and collects the collected wireless identification tag data by a client. The data is refined based on processing such as filtering, grouping, and code conversion, and the refined wireless identification tag data is provided to the client. For reference, tag data is processed per event cycle, and the client can directly set processing conditions based on an interface focused on international standardization defined in EPCglobal's ALE specification.

In detail, the tag data processing system of the wireless identification middleware includes a filtering unit 102, a change detection unit 104, a transmission set calculation unit 106, a data existence inspection unit 108, a previous data preservation unit 110, and a processing unit. The data grouping unit 112, the format converter 114, the report generator 116, and the transmitter 118 are included.

A detailed block diagram and processing method for each component will be described with reference to FIGS. 2 to 7.

The filtering unit 102 shown in FIG. 2 includes a filtering manager 120, a filtering pattern manager 122, and a filtering processor 124.

The filtering management unit 120 includes, as input data, a spec 126 in which processing conditions set by the client are expressed, report count information 128 including the number of information to be processed simultaneously, and the collecting unit 100. The received wireless identification tag raw data 130 is received.

The filtering manager 120 extracts the filtering condition 132 from the specification 126 of the input material, provides the extracted filtering condition 132 to the filtering pattern manager 122, and executes the filtering pattern manager 122. Let's do it.

The filtering pattern manager 122 analyzes the pattern in a code form that the filtering processor 124 can recognize the filtering condition 132 set by the client. Specifically, the filtering pattern manager 122 largely analyzes whether the wireless identification tag raw data 130 is filtered by a set included in a specific condition or a set excluded from a specific condition, and analyzes the analyzed result. The pattern list 134 is stored.

The filtering processing unit 124 generates the filtering data 136 by performing the filtering process including the wireless identification tag raw data 130 in a specific condition or the filtering process excluding the specific condition based on the pattern list 134.

The generated filtering data 136 is output as output data through the filtering management unit 120.

In other words, the filtering unit 102 classifies the radio identification tag raw data 130 into data that satisfies the processing condition set by the client and data that does not satisfy the processing condition set by the client, and refines the data.

An example of such a filtering process applied to a large logistics mart system will be described below.

In a large logistics mart system, each product has a unique radio identification tag and is placed on a shelf in a unique location. The goods on the shelf purchased by the buyer are automatically calculated by reading the wireless identification tag data at the checkout counter.

However, in the case of the A-mart, only the goods distributed in the A-mart should read and process the radio identification tag data. In other words, you shouldn't read something you've already bought at B-mart. To handle this, there are two types of filtering process.

First, filter only the A-mart products.

Second, filter out products other than A-mart products.

When filtering only A-mart goods, it is the filtering process included in a specific condition (A-mart goods), and when filtering goods other than A-mart goods means filtering process which excludes from a specific condition (A-mart goods).

In this way, if only the product of A-mart is filtered and managed, it can be processed more quickly. In other words, it is useful when only the wireless identification tag data required by the client needs to be processed.

3, the change inspection unit 104 includes a change management unit 138 and a change processing unit 140.

The change / absence management unit 138 is a specification 126 in which the processing conditions set by the client are expressed as the input data, the report count information 128 including the number of information to be processed simultaneously, and the filtering unit 102. The generated filtering data 136 and previous data 142 processed and preserved in an event cycle immediately before the current event cycle are received.

The change management unit 138 extracts the change condition 144 from the specification 126 of the input data, and changes the extracted change condition 144, the filtering data 136, and the previous data 142 of the input data. It is provided to the presence processing unit 140, and executes the change presence processing unit 140.

Herein, the change condition 144 may be a condition of outputting the changed case as "True" and the same case as "False". Of course, the present invention is not limited thereto, and may be a condition for outputting the changed case as "False" and the same case as "True".

The change processing unit 140 compares the filtering data 136 with the previous data 142 based on the change condition 144 and compares the comparison result with the change display character 146 such as "True" and "False". Will output The filter data 136 changed or the same according to the comparison result is output.

The filtering data 136 output from the change existence processing unit 140 is output as output data through the change existence management unit 138.

This change check is to allow the client to receive the changed data of the current event cycle or to receive the same data even if the same data is compared with the data of the previous event cycle according to the processing condition setting of the client.

The transmission set calculating unit 106 shown in FIG. 4 includes a transmission set managing unit 148 and a transmission set processing unit 150.

The transfer set management unit 148, as input data, includes a specification 126 in which processing conditions set by the client are expressed, report count information 128 including the number of information to be processed simultaneously, and a change check unit 104. Filtering data 136 outputted from and received previous data 142 processed and preserved in an event cycle immediately before the current event cycle are received.

The transport set manager 148 extracts the transport set condition 152 from the specification 126 of the input data, extracts the transport set condition 152, the filtering data 136, the previous data 142, and the input data. The change existence indication character 146 outputted from the change existence processing unit 140 is provided to the transmission set processing unit 150, and the transmission set processing unit 150 is executed.

The transmission set processing unit 150 confirms whether there is a change based on the input change indication character 146 received, and transmits the data 154 based on the transmission set condition 152, the filtering data 136, and the previous data 142. ) Is calculated.

The transmission data 154 calculated by the transmission set processing unit 150 is output as output data through the transmission set management unit 148.

Here, the transport set condition 152 set by the client is at least one of a data set of the current event cycle, a data set newly added in comparison with the previous data 142, and a data set excluded in comparison with the previous data 142. Can be.

For example, the transport set calculation function can be utilized when managing goods placed on a shelf. The dataset of the current event cycle contains all the product information on the shelf, the added dataset contains only the newly added product information on the shelf, and the excluded dataset contains only the product information missing from the shelf. Compare and process the data. Thus, the client side can be applied to the overall sales, theft prevention, etc. in conjunction with the product payment information.

The data presence inspection unit 108 illustrated in FIG. 5 includes a data presence management unit 156 and a data presence processing unit 158.

The data presence management unit 156 is, as input data, the specification 126 in which the processing conditions set by the client are expressed, the report count information 128 including the number of information to be processed simultaneously, and the transmission set calculating unit 106. Receive the data to be transmitted (154).

The data presence management unit 156 extracts the data presence condition 160 from the specification 126 of the input data, and extracts the data presence condition 160 and data 154 to be transmitted among the input data from the data presence processing unit 158. The data presence processing unit 158 is executed.

In this case, the data presence condition 160 may be set by the client to output "True" if data does not exist and to output "False" if data exists. Of course, it may be set to output "False" if data does not exist, and to output "True" if data exists, but is not limited thereto.

The data presence processing unit 158 checks the data 154 to be transmitted, determines whether there is data, and outputs a transmission presence indication character 162 ("True" or "False") based on the received data presence condition 160. In the meantime, the data 154 to be transmitted to the client is output.

The data to be transmitted 154 output from the data presence processing unit 158 is output as output data through the data presence management unit 156.

According to the data presence check result, the data can be sent to the client when the data exists.

As a result, when there is no data to be transmitted to the client, the wireless identification middleware can perform a new collection process without any subsequent processing, thereby enabling faster processing. The client can also receive data only if the collected wireless identification tag data is present, thereby receiving more useful data.

In addition, when there is data to be transmitted and when there is no data, processing can be performed according to the processing condition setting of the client, thereby enabling more flexible processing. In other words, data may be transmitted even if there is no report to the client according to the setting condition of the client.

The previous data preserving unit 110 uses the previous data to utilize the data to be transmitted 154 outputted from the transmission set calculating unit 106 or the data existence check unit 108 of the current event cycle as the previous data 142 in the next event cycle. Save to a storage table. The previously stored data 142 is utilized by the change detection unit 104 and the transmission set calculation unit 106 in the next event cycle. Of course, in some cases, the filtering data 136 output from the filtering unit 102 may be stored in the previous data storage table in order to utilize the previous data 142 in the next event cycle.

The data grouping unit 112 illustrated in FIG. 6 includes a grouping manager 164, a grouping pattern manager 166, a group name manager 168, and a grouping processor 170.

The grouping management unit 164 is input data, including a specification 126 in which processing conditions set by a client are expressed, report count information 128 including the number of information to be processed simultaneously, and a transmission set calculating unit 106. Receives the data to be transmitted (154) is generated.

The grouping manager 164 extracts the group condition 172 from the specification 126 of the input data, provides the extracted group condition 172 to the grouping pattern manager 166, and executes the grouping pattern manager 166. .

The grouping pattern manager 166 analyzes the group condition 172 in a code form that can be recognized by the group name manager 168 and the grouping processor 170, and stores the analyzed result as a pattern list 174. .

The group name manager 168 generates a group name list 176 based on the pattern list 174 and the data 154 to be transmitted.

The grouping processor 170 generates the grouping data 178 by performing matching processing on the data group desired by the client based on the generated group name list 176 and the data 154 to be transmitted.

The grouping manager 164 generates a report list 180 for transmitting to the client based on the grouping data 178.

The data grouping unit 112 performs processing similar to the filtering unit 102, but unlike filtering, the group name is extracted from the data 154 to be transmitted by the corresponding group condition 172 before data matching.

An example of such a data grouping process is to provide a client with a group of products ubiquitous in a mart by grouping by product or manufacturer. If the client wants to receive product information for each company, such as Nongshim, Samyang, or if you want to receive product information for each product of Nongshim. For example, if the purchaser has purchased three nongshim shrimp crackers, the grouping may be three wireless identification tag data in the group name of nongshim shrimp crackers.

The format converter 114 shown in FIG. 7 includes a format conversion manager 182, a group counting processor 184, a group list manager 186, and a format conversion processor 188.

The format conversion management unit 182, as input data, includes a specification 126 in which processing conditions set by a client are expressed, report count information 128 including the number of information to be processed simultaneously, and a data grouping unit 112. The report list generated in 180 is received.

The format conversion management unit 182 extracts the format conversion condition and the counting condition from the specification 126 of the input data.

The format conversion management unit 182 divides the counting processing type and the format conversion processing type according to the extracted counting condition and executes them. That is, the format conversion management unit 182 executes the group counting processing unit 184 and the group list management unit 186 according to the counting conditions "True" and "False".

If the counting condition is "True" (192), the group counting processor 184 is executed to generate the count data 196 based on the report group 190 which is a group of the report list among the input data.

If the counting condition is " False " (194), the group list manager 186 is executed to execute the format conversion condition 198 and the data 200 to be converted based on the report group 190 which is a group of the report list among the input data. Is provided to the format conversion processing unit 188, and the format conversion processing unit 188 is executed.

The format conversion processing unit 188 converts the radio identification tag data into a code set by the client to generate the final transmission data 202. Codes that can be converted include Serialized Global Trade Identification Number (SGTIN), Global Individual Asset Identifier (GIAI), Serialized Global Location Number (SGLN), Global Returnable Asset Identifier (GRAI), Serial Shipping Container Code (SSCC), General GID (General) IDentifier).

The final transmission data 202 is stored in the form of the final transmission list 204, which is the final data transmitted to the client by the group list management unit 186.

The format conversion manager 182 executes the group counting processor 184 and the group list manager 186 to be divided into counting and format conversion as described above, but may process only one of the two. It is also possible to process both types in parallel.

For example, let's say you have an application system that distributes a ticket with a wireless identification tag to people entering an exhibition, and reads and manages the entrance readers by a wireless tag reader at the entrance.

At this stage, it is possible to process data when it is necessary to receive data indicating which people entered the application system and data about how many people entered.

In this step, the primitive radio identification tag data may be converted into a format suitable for the application system, and the number of data converted through the counting operation may be simultaneously provided to the client.

On the other hand, the client may be provided with only the code converted according to the setting conditions, or only the counting data may be provided when only the number of people who enter the exhibition hall.

The report generator 116 generates a report received by the client based on the final transmission list 204, which is the final data generated by the format converter 114, and is processed based on XML (extensible markup language).

The transmitter 118 transmits the report generated by the report generator 116 to the client. At this time, the transmission unit 118 may transmit the report through at least one of the Socket, RMI, HTTP, SOAP communication interface.

On the other hand, the report count information 128 that is not described indicates the number of cases that the processing unit must process at the same time. That is, it means the number of information to be processed in one event cycle.

Although the tag data processing method and system of the wireless identification middleware according to the present invention have been described with reference to the drawings illustrated as above, the present invention is not limited by the embodiments and drawings disclosed in the present specification, and the invention Of course, various modifications can be made by those skilled in the art within the scope of the technical idea.

As described above, according to the tag data processing method and system of the wireless identification middleware according to the present invention, the client directly sets the processing conditions based on the interface focused on international standardization defined in the ALE specification of EPCglobal, and filters or changes them. There is an effect of processing such as inspection, transmission set calculation, data existence inspection, data grouping, format conversion, and the like.
