Description

  The present invention relates to a reading system that reads identification information attached to an article.

  In recent years, large shopping malls and stores have appeared, and a wide variety of products are handled. Along with this, in order to increase the appeal power of each product to customers (consumers), the display mode (how to show and arrange) of the product has been devised. Here, one of the operations in the store is inventory management of products. In a large store or the like, it is an issue to efficiently perform inventory for inventory management.

  Therefore, in the wireless tag system of Patent Document 1, it has been proposed to efficiently perform inventory using a plurality of wireless tag readers. The wireless tag reader incorporates a first communication mode for performing batch reading of wireless tags attached to products and a second communication mode for performing individual reading of wireless tags, and the wireless tag reader is read in each communication mode. The identification information is transmitted to the server.

  According to such a technique of Patent Document 1, since a plurality of workers can go around the store while reading the RFID tag at once, the work time can be shortened as the number of workers increases.

JP, 2006-177778, A

  Here, at the beginning of the reading operation, the workers circulate in the store through different routes, but the display mode of the products is not always regular, and the display of various products as described above particularly in large stores. Since the mode is adopted, there is a high possibility that the cyclic routes of the workers become irregular and the cyclic routes of the respective workers overlap. When the circulation route overlaps, each wireless tag reader of the worker reads identification information from the same product, that is, duplicate reading between so-called wireless tag readers occurs.

  As a countermeasure when duplicate reading occurs, deduplication processing that eliminates duplicate identification information in server processing can be cited, but as the number of workers increases, the number of products increases. Since the load increases, the server may wait for processing when performing inventory using a plurality of RFID tag readers.

  In view of the above problems, an object of the present invention is to provide a reading system that can reduce the burden of deduplication processing in a server while performing reading by a plurality of workers.

In order to achieve the above object, the present invention provides a reading system comprising a server and a plurality of portable reading terminals capable of communicating with the server,
The plurality of portable reading terminals read the identification information attached to a plurality of articles at once, a reading unit that transmits the read identification information to a server, and the server via the server. A receiving unit for receiving identification information from each other, and a duplication confirmation unit for confirming duplication between the identification information read by each reading unit and the received identification information,
As a result of the confirmation, the transmission unit transmits identification information that is not duplicated among the identification information read by each of the reading units to the server.

The server also stores the file including the identification information of the article to be read, and erases the identification information for the file based on the identification information received from the plurality of portable reading terminals. An update unit that performs transmission, and a transmission unit that transmits the file to each portable reading terminal. The plurality of portable reading terminals receive the file from the server and calculate based on the received file A progress notifying unit for notifying the user of the progress made.

  The plurality of portable reading terminals include a reading notification unit that notifies a user when the identification information read by each of the reading units does not overlap as a result of the confirmation. .

  The plurality of portable reading terminals include a position information acquisition unit that acquires position information, and the transmission unit transmits the position information together with the non-overlapping identification information to the server.

  According to the present invention, a plurality of portable reading terminals can mutually receive the read identification information via the server. And the duplication with the identification information which each read and the received identification information is confirmed by the duplication confirmation part. As a result, since only the identification information that is not duplicated is sent to the server, it is possible to reduce the burden of deduplication processing in the server. For this reason, even if the number of portable reading terminals used for reading or the number of articles to be read increases, deduplication processing in the server can be extremely suppressed, and there is no possibility of entering into a server processing waiting state.

Here, in the memory 26 of this embodiment, identification information for identifying each product from each other is stored in advance. Such merchandise is displayed with a devised way of showing and arranging to customers.

  In order to read the identification information from each displayed product and grasp the number of products in the store, a plurality of workers go around the store while holding the mobile readers 12a to 12c over the product. As shown in FIG. 1, the mobile readers 12 a to 12 c have a configuration in which a reading unit 30 is combined with a portable information terminal 28.

  The reading unit 30 is a unit that collectively reads identification information from a plurality of RF tags 20 by an anti-collision function, and an antenna 32 is attached to the tip of a gun-type housing.

  As shown in FIG. 2, a reading circuit 34 that is electrically connected to the antenna 32 is provided in the housing. The reading circuit 34 includes an oscillation circuit (not shown) that generates a carrier wave, a modulation circuit (not shown) that superimposes a command on the carrier wave generated by the oscillation circuit, and a carrier wave on which the command is superimposed. A transmitting circuit (not shown) for transmitting, a receiving circuit (not shown) for receiving a signal from the RF tag 20 that enters via the antenna 32, and a demodulation for demodulating the signal from the RF tag 20 A circuit (not shown). Such a reading circuit 34 is electrically connected to a CPU 36 that is also provided in the housing. The CPU 36 executes a program stored in advance in the memory 38 to control the reading circuit 34 and read identification information from the RF tag 20. In this manner, the CPU 36, the reading circuit 34, and the antenna 32 function as a reading unit 40 (FIG. 3) that reads identification information from the RF tag 20.

  In addition to the above program, the memory 38 temporarily stores identification information read from the RF tag 20 as character string format read information (FIG. 4), and once read the identification information in character string format. A read area (FIG. 4) for accumulating as read information is provided. In this manner, the memory 38 functions as the first storage unit 42 (FIG. 3) that stores the identification information (read information and read information). The read information and the already read information are checked for duplication by the CPU 36 that executes the program. Thus, the CPU 36 functions as a first duplication confirmation unit 44 (FIG. 3) that confirms duplication of identification information (read information and read information).

  A trigger switch 46 is electrically connected to the input of the CPU 36. The trigger switch 46 is a switch operated by an operator who reads a product, and is provided in a grip portion 48 formed in a gun-type housing as shown in FIG.

  The housing of the reading unit 30 includes a barrel portion 50 that extends horizontally from the upper end of the grip portion 48 in addition to the grip portion 48 described above. As shown in FIG. 5, a pedestal portion 52 for placing the portable information terminal 28 is formed on the upper surface of the barrel portion 50. On the upper surface of the pedestal portion 52, a connector terminal 56 for connection with the connector pattern 54 of the portable information terminal 28 is exposed. The connector terminal 56 is connected to the CPU 36 (FIG. 2) via a controller (not shown) that performs communication processing with the portable information terminal 28. Note that a magnet 58 for holding the portable information terminal 28 is built in the pedestal portion 52.

  As shown in FIGS. 1 and 5, the portable information terminal 28 is a smart device typified by a smartphone or a tablet computer, and a case 60 that covers a side surface and a back surface of the smart device is attached. Such a portable information terminal 28 is placed so that the back surface (the back surface of the case 60) is in contact with the pedestal portion 52 described above. A connector pattern 54 is exposed on the back surface of the case 60, and the connector pattern 54 is connected to the connector terminal 56 of the pedestal 52. Each of the connector patterns 54 is connected to an external device connection connector (not shown) of the portable information terminal 28 through wiring (not shown) arranged in the case 60. The external device connector is connected to the CPU 62 (FIG. 2) via a controller (not shown) that performs communication processing. As described above, the portable information terminal 28 and the reading unit 30 are electrically connected via the electric circuit including the connector pattern 54, the connector terminal 56, and the wiring. Further, a magnet 64 is provided inside the back surface of the case 60, and the portable information terminal 28 is held by the reading unit 30 by the magnet 64 and the magnet 58 of the pedestal 52 being attracted to each other.

  As shown in FIG. 2, the portable information terminal 28 includes a memory 66, a wireless module 68, a display 78, and a touch panel 80 in addition to the CPU 62 described above. The memory 66 causes each of the above components to function as the transmission unit 70 (FIG. 3), the second duplication confirmation unit 76 (FIG. 3), the reception unit 72 (FIG. 3), and the second storage unit 74 (FIG. 3). The program is stored. Specifically, the wireless module 68 is a well-known module for connecting to the network N, and is controlled by the CPU 62 to receive the information from the server 14 and the transmission unit 70 that transmits information to the server 14. Functions as a receiving unit 72. The memory 66 functions as a second storage unit 74 that stores information received from the reading unit 30 or the server 14. The CPU 62 functions as a second duplication confirmation unit 76 that confirms whether or not the identification information (reading information) received from the reading unit 30 is duplicated. The display 78 is disposed on the front side of the portable information terminal 28 and functions as a progress notification unit 92 that notifies the worker of the progress status by being controlled by the CPU 62. The touch panel 80 is disposed on the display 78 and functions as an input unit (not shown) that inputs the coordinates of the position touched by the operator to the CPU 62. Further, reader identification information (for example, reader01, reader02, reader03) for identifying each mobile reader 12a-12c is defined in the program.

  The server 14 that can communicate with the mobile readers 12a to 12c includes a CPU, a memory, and a network module (not shown). The memory stores a program that defines processing to be described later. When the CPU executes the program, each of the above-described components has a transmission unit 82, a reception unit 84, and a storage unit 86 as shown in FIG. , Functions as the update unit 88. Specifically, the network module is a known module for connecting to the network N, and is controlled by the CPU to receive the information from each of the mobile readers 12a to 12c, and each mobile reader 12a. It functions as a transmission unit 82 that transmits information to 12c. The CPU functions as an update unit 88 that updates the registration file based on the identification information received from each of the mobile readers 12a to 12c. Here, the registration file is a file listed so that the identification information received from each of the mobile readers 12a to 12c does not overlap. In addition to the above program, the memory stores a read file and a registration file that store identification information (read information) received from each of the mobile readers 12a to 12c as read information in a character string format, as shown in FIG. It functions as a storage unit 86 (FIG. 3) for storing. In the present embodiment, a read file is provided so as to correspond to the reader identification information of each of the mobile readers 12a to 12c.

  An operation flow of the reading system 10 including the plurality of mobile readers 12a to 12c and the server 14 as described above will be described mainly with reference to FIGS. Since the mobile readers 12a to 12c operate in the same manner, only the mobile reader 12a will be described here.

  First, the mobile reader 12a executes an initialization process (s100). In the initialization process (s100), the CPU 62 of the portable information terminal 28 and the CPU 36 of the reading unit 30 clear information storage areas provided in the memories 66 and 38, respectively.

  Next, the mobile readers 12a to 12ca execute a reading process (s101). In the reading process (s101), the CPU 62 of the portable information terminal 28 transmits a reading start command to the reading unit 30. When receiving the reading start command, the CPU 36 of the reading unit 30 periodically checks the input from the trigger switch 46. When detecting the input of the trigger switch 46, the CPU 36 controls the reading circuit 34 to establish communication with the RF tag 20 through the antenna 32, and reads identification information from the plurality of RF tags 20. Here, when reading the identification information, an anti-collision function using a known time slot method or bit collision method is used, and the identification information is collectively read from the plurality of RF tags 20. The read identification information (hereinafter referred to as “read information”) is temporarily stored as a character string in the reading area as shown in FIG.

  Next, the mobile reader 12a executes a first duplication confirmation process (s102). In the first duplication confirmation process (s102), the CPU 36 of the reading unit 30 confirms the presence or absence of duplication by comparing the read information with the read information in the read area. The presence or absence of duplication is confirmed, for example, by comparing the read information stored as a character string with the read information (string compare). As a result of the comparison, the duplicated (matched) read information is cleared from the read area. Is done. In the first duplication check process (s102) that is executed for the first time immediately after the start of the reading operation, the already-read area is cleared by the initialization process (s100).

  As a result of checking the presence or absence of duplication, if all of the read information that has been batch read is duplicated with the already read information (when all the read information is cleared) (s103: Yes), the processing so far Is repeated. On the other hand, as shown in FIG. 4, when there is non-overlapping read information “00A0000C to 00A00012” (s103: No), the non-overlapping read information is additionally registered as a character string in the already-read area ( s104) and transmitted to the portable information terminal 28 through the electric circuit. The read information once read in this way is accumulated in the reading unit 30 as already read information.

  Next, the mobile reader 12a executes an acquisition process (s105). In the acquisition process (s105), the CPU 62 of the portable information terminal 28 downloads the read information of the other mobile readers 12b and 12c from the server 14. Specifically, the CPU 62 of the portable information terminal 28 sends the reader identification information “reader01” given to the mobile reader 12a and requests transmission of the read file.

  When receiving the request (s200: Yes), the CPU of the server 14 transmits a read file corresponding to the reader identification information “reader02” and “reader03” different from the received reader identification information “reader01” (s201). . When the CPU 62 of the portable information terminal 28 downloads the read file, the CPU 62 stores it in the other reader read information storage area provided in the memory 66.

  Next, the mobile reader 12a executes a second duplication confirmation process (s106). In the second duplication confirmation process (s106), the CPU 62 of the portable information terminal 28 checks the presence or absence of duplication by comparing the read information received from the reading unit 30 with the read file. The presence or absence of duplication is performed by comparing character strings in the same manner as in the first duplication confirmation process (s102), and the duplicated reading information is cleared. As a result, the read information “00A00011” and “00A00012” that do not overlap with the information in the already-read file are transmitted to the server 14 together with the reader identification information as new read information (s107).

  Thereafter, the CPUs 62 and 36 of the portable information terminal 28 and the reading unit 30 clear the reading information in the memories 66 and 38 (s108), from the reading process (s101) described above to the reading information clearing process (s108). The series of processes is repeatedly executed. And the process of the mobile reader 12a demonstrated above is similarly performed in the other mobile readers 12b and 12c.

  When the server 14 receives new read information from each of the mobile readers 12a to 12c (s202: Yes), a reception process (s203) and a registration process (s204) are executed. In the reception process (s203), the CPU of the server 14 receives new read information from the mobile reader 12a. In the registration process (s204), the CPU additionally registers the received read information as read information in a read file corresponding to the reader identification information.

  When the CPU 14 of the server 14 has not received new read information from each of the mobile readers 12a to 12c for a certain period of time (s205: Yes), it executes an update process (s206). In the update process (s206), the CPU of the server 14 reads the read information stored in each read file and lists them so as not to overlap.

  According to the reading system 10 of the present embodiment described above, the mobile readers 12a to 12c mutually receive the identification information read via the server 14. In each of the mobile readers 12a to 12c, not only the first duplication confirmation unit 44 confirms duplication with the already-read information (first duplication confirmation processing s102), but also the second duplication confirmation unit 74 uses another mobile device. Since the duplication with the read information of the reader is confirmed (second duplication confirmation processing s106), the identification information transmitted from the mobile readers 12a to 12c to the server 14 is very unlikely to be duplicated. The burden of deduplication processing is reduced.

  [Second Embodiment]

  The reading system of the second embodiment has the same hardware configuration as that of the first embodiment, but each mobile reader 12a to 12c receives the registration file from the server 14, and the third duplication check based on the registration file. This is different from the first embodiment in that the processing is executed. Hereinafter, the operation flow of the reading system of the present embodiment will be described with reference to FIG. In addition, about the structure and process similar to 1st Embodiment, the same code | symbol is attached | subjected, description is abbreviate | omitted suitably, and suppose that it demonstrates focusing on a structure and process different from 1st Embodiment.

  After executing the initialization process (s100), the mobile readers 12a to 12c obtain a registration file from the server 14 (s109). Specifically, the CPU 62 of the portable information terminal 28 controls the wireless module 68 to establish communication with the server 14 via the network N, and requests the server 14 to transmit a registration file. Upon receiving the request, the server 14 reads the registration file stored in the memory and transmits it to the portable information terminal 28 (s207). Note that immediately after the reading operation is started, the contents of the registration file are cleared (empty).

  Next, in the mobile readers 12a to 12c, the reading unit 30 executes the reading process (s101), the first duplication confirmation process (s102), and the registration process to the already-read area (s104), Read information that does not overlap with the information is transmitted to the portable information terminal 28.

  When the reading information is received from the reading unit 30, the portable information terminal 28 executes a third duplication confirmation process (s110). In the third duplication confirmation process (s110), the CPU 62 of the portable information terminal 28 confirms the presence or absence of duplication by comparing the read information received from the reading unit 30 with the information in the registration file acquired from the server 14. As a result, the CPU 62 of the portable information terminal 28 transmits read information that does not overlap with the information in the registration file to the server 14 as new read information (s107). Thereafter, the CPUs 62 and 36 of the portable information terminal 28 and the reading unit 30 clear the reading information in the memories 66 and 38 (s108). A series of processes from the registration file acquisition process (s109) to the read information clear process (s108) described above are repeatedly executed in each of the mobile readers 12a to 12c.

  The server 14 executes the update process (s208) every time new read information is received by the reception process (s203). In the update process (s208), the CPU of the server 14 additionally registers new read information received from each of the mobile readers 12a to 12c in the registration file as already read information. Then, the server 14 repeatedly executes a series of processes from the registration file transmission process (s207) to the update process (s208) described above.

  The reading system according to the present embodiment checks the duplication of the read information and the read information in the registration file acquired by the mobile readers 12 a to 12 c from the server 14, and transmits only the read information that is not duplicated to the server 14. . In the server 14, the registration file is updated each time new reading information is received from each of the mobile readers 12a to 12c. As described above, since the duplication confirmation process is executed in each of the mobile readers 12a to 12c based on the registration file updated each time, duplication of new read information transmitted to the server 14 is reduced, and duplication in the server 14 is performed. The load of exclusion processing will be reduced.

  Moreover, each mobile reader 12a-12c has the advantage that the progress of reading work can be grasped | ascertained by displaying the content of the received registration file on the display 78 of the portable information terminal 28.

  [Third Embodiment]

  The reading system of the third embodiment has the same hardware configuration as that of the first and second embodiments, but the server 14 has an application file instead of a registration file, and each of the mobile readers 12a to 12c has The difference is that the third duplication confirmation process is executed based on the consumption file. Hereinafter, configurations and processes similar to those in the first embodiment and the second embodiment will be denoted by the same reference numerals, description thereof will be omitted as appropriate, and different configurations and processes will be mainly described.

  The application file is a file in which products managed in the store are listed, and is composed of a plurality of records in which identification information is associated with each product information. The product information is product information represented by the product name, model number, and the like. Such a consumption file is stored in the storage unit 86 of the server 14 before the reading operation is started.

  Here, in the third embodiment, the server 14 erases the read product from the list by setting a read flag in the record corresponding to the identification information (new read information) received from each of the mobile readers 12a to 12c. It is going to be included. Hereinafter, a specific operation flow will be described with reference to FIG.

  In response to the file transmission request (s109) of the mobile readers 12a to 12c, the server 14 transmits the consumption file to the mobile readers 12a to 12c (s207).

  In the mobile readers 12a to 12c, after obtaining the consumption file (s109), the reading process (s101), the first duplication confirmation process (s102), and the registration process to the already-read area (s104) are executed. Then, read information that does not overlap with the read information in the read area is transmitted to the portable information terminal 28.

  Next, in the mobile readers 12a to 12c, a third duplication confirmation process is executed based on the acquired consumption file (s110). In the third duplication confirmation process (s110) of this embodiment, the CPU 62 of the portable information terminal 28 extracts a record for which the reading flag is not set from the consumption file, and the identification information included in the extracted record The read information received from the reading unit is checked against the presence of duplication. As a result, when there is non-overlapping read information, the read information is transmitted as new read information to the server 14 (s107). In the mobile readers 12a to 12c, the reading information is cleared (s108), and the file acquisition process (s109) is executed.

  The server 14 executes the update process (s208) each time new read information is received by the reception process (s203). In the update process (s208) of this embodiment, the CPU of the server 14 performs a search using the received new read information as a key for the consumption file, and indicates that the record corresponding to the searched identification information has been read. Set the reading flag to be used. By setting the reading flag, the identification information in the consumption file is erased. The server 14 repeatedly executes a series of processes from the file transmission process (s207) to the update process (s208) described above.

  In the present embodiment, the mobile readers 12a to 12c execute notification processing for notifying the progress of reading work. The notification process is preferably executed each time the portable information terminal 28 of the mobile readers 12a to 12c receives the application file from the server 14. Specifically, when receiving the erase file, the CPU 62 of the portable information terminal 28 counts the number of records in which the reading flag is not set in the records included in the erase file, and causes the display 78 to display the count result. Thereby, it becomes possible to notify the user who uses the mobile readers 12a to 12c of the remaining number of products to be read.

  As another notification mode, the CPU 62 multiplies the reciprocal of the total number of records in the application file by the number of records for which the reading flag has been set to obtain the ratio of the number of read products, and displays the ratio in the display 78. To display. As a result, the ratio of the number of products read can be notified to the user. As described above, the CPU 62 and the display of the portable information terminal 28 function as a progress notification unit 92 (FIG. 3) that notifies the user of the progress of the reading operation.

  As described above, the reading system according to the present invention has been described based on the embodiment. However, the present invention is not limited to the above-described form, and may be implemented in the following form, for example.
