  FIG. 8 is a diagram illustrating a display example of a screen displayed on the display unit 201 of the operation terminal 200 when the communication setting element diagnosis process is performed. FIG. The displayed communication setting element designation screen, FIG. 8B is a tag confirmation screen displayed before the start of the communication setting element diagnosis.

  When the communication processing unit CP executes the communication setting element diagnosis process, first, the communication setting element designation screen (first display means) 300 of FIG. 8A is displayed on the display unit 201 of the operation terminal 200. .

A designated value input box 302 for designating a setting pattern of setting elements is provided (in the illustrated example, in a so-called pull-down menu mode).

  The operator can select and designate as a diagnosis target by entering a check mark in the diagnosis target check box 301 of the seven communication setting elements of this example to be automatically diagnosed. This is because, when the operator already knows the setting pattern of a specific communication setting element for the RFID tag T related to diagnosis (in the example shown, each of standard, CRC reception, bandpass, reception start time, and reception gain). If the optimum setting pattern of communication setting elements is known), the processing time can be shortened by omitting the diagnosis without entering a check mark in the check target 301 of the communication setting elements. Then, for the communication setting element whose diagnosis is omitted in this manner, a known optimum setting pattern is designated in each designated value input box 302. Although this is not particularly illustrated, the candidate value may be selected and specified by a pull-down menu or may be directly entered in the specified value input box 302. It should be noted that the specified value input box 302 cannot be operated or entered in a communication setting element selected as a diagnosis target by entering a check mark in the diagnosis target check box 301. The diagnosis target check box 301 in which a check mark is entered constitutes the first operation means described in each claim, and the diagnosis target check box 301 in which no check mark is entered constitutes the second operation means.

  When the “diagnosis start” button 303 (lower left in FIG. 8A) is operated in the state where the designation input as described above is completed, the tag confirmation screen 400 of the next FIG. 8B is displayed. . In this tag confirmation screen 400, a message prompting the operator to install (fix) the RFID tag T to be diagnosed on the RFID tag communication apparatus 100 (indicated as a reader in the figure) is displayed, and an “OK” button 401 is displayed. The search for the optimum communication setting element is started by operating (lower left in FIG. 8B).

  FIG. 9 is a flowchart showing a control procedure related to the communication setting element diagnosis process executed by the CPU 203 of the operation terminal 200. This communication setting element diagnosis process is one of the processes executed in the above-described communication processing unit CP, and this flow is started when an execution start is instructed through an operation of the operation unit 202 or the like. Alternatively, various communication conditions as shown in each stage of FIG. 7 are sequentially switched to try wireless communication with the wireless tag T, and this flow is automatically started when communication fails. Also good.

  In FIG. 9, first, in step S <b> 5, the communication setting element designation screen 300 (see FIG. 8A) is displayed on the display unit 201 of the operation terminal 200.

  Next, the process proceeds to step S10. On the communication setting element designation screen 300 displayed in step S5, the communication setting element selection designation and the non-diagnosis target communication are designated by the operator's operation via the operation unit 202. A setting is made based on a setting pattern specified for the setting element (hereinafter referred to as a specified pattern). When the “diagnosis start” button 303 is operated, the process proceeds to the next step S15.

  In step S15, the tag confirmation screen 400 (see FIG. 8B) is displayed on the display unit 201 of the operation terminal 200. When the “OK” button 401 is operated, the process proceeds to the next step S100.

  In step S100, a communication setting element search is performed by searching for and determining the optimum setting pattern of the communication setting element selected and designated as the diagnosis target using the designation pattern of the non-diagnostic communication setting element set in step S10. Processing (see FIG. 10 described later) is executed.

  Next, the process proceeds to step S20, and it is determined whether or not the search for the optimum setting pattern of all the communication setting elements to be diagnosed has been successfully performed in the communication setting element search process of step S100. If the communication setting element search is successful, the determination is satisfied, and the process proceeds to the next step S25, where a result screen 500 that displays a list of optimum setting patterns of each designated or searched communication setting element (see FIG. 12 described later). Is displayed on the display unit 201 of the operation terminal 200. Then, when the “Reflect to device” button 501 is operated, the process proceeds to the next step S30, and a communication condition composed of a combination of setting patterns of each communication setting element (setting pattern described in step S140 of FIG. 11 described later) is newly set. This is registered in the tag type registration table (see FIG. 7) as the optimum communication condition on the RFID tag communication apparatus 100 side for the tag type, and this flow is terminated.

  On the other hand, if the search for the optimum communication setting element has failed in the determination in step S20, the determination is not satisfied, and an error screen (not shown) indicating that the communication setting element search has failed in step S35. Is displayed on the display unit 201 and this flow is terminated.

  FIG. 10 is a flowchart showing a detailed procedure of the communication setting element search process executed in step S100 in FIG. The flowchart shown in the figure follows the example shown in FIG. 8A, and a specified pattern is input to the communication setting elements of the standard, CRC reception, band pass, reception start time, and reception gain, and the bit rate and modulation. The case where the optimum setting pattern of each depth is searched is shown as an example.

  In FIG. 10, first, in step S105, a communication setting element in which a specified pattern is input as a non-diagnosis target by an operation on the communication setting element specifying screen 300 in step S10 in FIG. 9 (standard, CRC reception in this example). , Band pass, reception start time, and reception gain) are fixedly set.

  In step S110, the minimum error rate variable Emin is initialized to 100%.

  Next, the process proceeds to step S115, where a bit rate setting pattern, which is one of the communication setting elements to be diagnosed in this example, is initially set. In this example, since the specification pattern of the standard (ISO15693 1-out-of-4 in the example shown in FIG. 8A above) is input, the setting pattern (6 .62 kbps (see FIG. 6) is initially set.

  Next, the process proceeds to step S120, and a modulation depth setting pattern, which is one of the communication setting elements to be diagnosed in this example, is initially set. In this example, a setting pattern (7%; see FIG. 6) of the lowest value that the modulation depth can take is initially set.

  Next, the process proceeds to step S200, in which wireless communication with the communication target wireless tag T is performed using a combination of setting patterns of each communication setting element (in this example, bit rate and modulation depth; the same applies hereinafter). An error rate measurement process (see FIG. 11 described later) for measuring an error rate (processing failure rate) E is executed.

  Next, the process proceeds to step S125, and it is determined whether or not the error rate E measured in step S200 is smaller than the minimum error rate Emin at this time. If the error rate E is less than the minimum error rate Emin, the determination is satisfied. That is, of the repeated measurement of the error rate while variously changing the combination of the setting patterns of each communication setting element so far, the wireless communication by the combination of the setting patterns of each communication setting element at this time is performed best. (The error rate is the lowest) and the process proceeds to step S130. In step S130, the value of the minimum error rate Emin is updated with the value of the error rate E at this time. Thereafter, in step S135, the setting pattern combination of each communication setting element at this point is stored as an optimum setting pattern combination, and the process proceeds to step S140.

  On the other hand, if the error rate E is equal to or greater than the minimum error rate Emin in step S125, the determination is not satisfied, and the routine goes directly to step S140.

  In step S140, it is determined whether the minimum error rate Emin is 0%. If the minimum error rate Emin is 0%, the determination is satisfied, and the routine goes to Step S145. In step S145, it is determined that the combination of the setting patterns of the communication setting elements stored at this time is the combination of the optimum setting patterns of the communication setting elements, and the combination setting search of the optimum setting patterns of the communication setting elements is performed. It is considered that it has succeeded (reflected in the determination of step S20 in FIG. 9), and this flow is finished.

  On the other hand, if the minimum error rate Emin is not 0% in step S140, the determination is not satisfied, and the routine goes to step S150.

  In step S150, it is determined whether or not the modulation depth at this point is set to the last setting pattern (for example, 100%, which is the highest setting value that the modulation depth can take; see FIG. 6). If the modulation depth is not set to the last setting pattern, the determination is not satisfied, that is, the modulation depth is still considered to have another setting pattern to be switched, and the modulation depth is changed to the next setting pattern (for example, in step S155). Next, after returning to step S200, the same procedure is repeated. On the other hand, if the modulation depth is set to the last setting pattern, the determination is satisfied, and the routine goes to Step S160.

  In step S160, the bit rate at this time is set to the last setting pattern (for example, 26.48 kbps, which is the highest setting value that can be taken in accordance with the ISO 15693 1-out-of-4 standard of this example; see FIG. 6). It is determined whether or not it has been done. If the bit rate is not set to the last setting pattern, the determination is not satisfied, i.e., the bit rate is still considered to have another setting pattern to be switched, and the bit rate is changed to the next setting pattern (e.g., Switch to the next higher setting value). Then, it returns to step S120 and repeats the same procedure.

  On the other hand, if the bit rate is set to the last setting pattern in step S160, the determination is satisfied, and the routine goes to step S170.

  In step S170, it is determined whether or not the minimum error rate Emin is equal to or less than a reference value (for example, set and stored in advance as an appropriate value) that can be considered to be sufficiently low. If the minimum error rate Emin is below the reference value, the determination is satisfied, and the routine goes to Step S145. In step S145, as described above, the combination of the setting patterns of the communication setting elements stored at this time is the optimum combination of the setting patterns of the communication setting elements that can perform sufficiently good wireless communication with the wireless tag T. This flow is terminated.

  On the other hand, when the minimum error rate Emin is larger than the reference value, the determination is not satisfied, that is, it is considered that the optimum setting pattern capable of performing sufficiently good wireless communication with the wireless tag T cannot be searched and determined. Moving to S175, it is assumed that the communication setting element search has failed (reflected in the determination of step S20 in FIG. 9), and this flow is finished.

  By performing the control procedure according to the above flow, it is possible to search for a combination of optimum setting patterns of the communication setting elements of the bit rate and the modulation depth that are diagnosis targets in the example illustrated in FIG. In the above, the case where the optimum setting pattern is searched only for the two communication setting elements of the bit rate and the modulation depth has been described as an example, but the same applies when searching for the optimum setting pattern for the other communication setting elements. It can be done by the method. In this case, for example, a loop procedure equivalent to the procedure of step S115, step S160, and step S165 corresponding to the bit rate may be applied to the communication setting elements to be searched and executed so as to overlap the loop. . In other words, since seven communication setting elements are provided in the example of this embodiment, communication is attempted for all combinations of entertainment patterns of each communication setting element by a flow procedure having a maximum of seven loops. Measuring the error rate is sufficient. Conversely, only the optimum setting pattern of one communication setting element can be searched for using the same method as described above (otherwise, a designated pattern is used).

  FIG. 11 is a flowchart showing a detailed procedure of the error rate measurement process executed in step S200 in FIG. In this example, the number of trials of wireless communication is 10 times, and the ratio of the number of times of failure is measured as the error rate E.

  In FIG. 11, first, in step S205, the value of the counter variable C is initialized to 1, and the value of the failure variable F is initialized to 0.

  In step S210, a control signal is output to the transmission unit 142 of the high-frequency circuit 102. In this example, a tag ID read command signal is transmitted. That is, the RFID tag communication apparatus 100 obtains ID information stored in the RFID tag circuit element To of the RFID tag T based on the setting of each communication setting element at this time (in this example, as an inquiry signal) The tag ID read command signal) is generated. Then, the tag ID read command signal is transmitted to the RFID tag circuit element To as a communication target via the communication antenna 101.

  In step S215, a reply signal (including a tag ID) transmitted from the RFID circuit element To be communicated in response to the tag ID read command signal is received via the communication antenna 101. 143.

  Next, the process proceeds to step S220, and it is determined whether or not the tag ID of the RFID circuit element To has been normally read based on the received reply signal. If the tag ID cannot be read normally, the determination is not satisfied, and the value of the failure variable F is incremented by 1 in the next step S225, and then the process proceeds to step S230. On the other hand, if the tag ID can be read normally, the determination is satisfied, and the routine goes directly to Step S230.

  In step S230, it is determined whether the value of the counter variable C is 10. If the value of the counter variable C is not 10 (less than 10) at this time, the determination is not satisfied, and the value of the counter variable C is incremented by 1 in step S235 and the process returns to step S210, and the same procedure is repeated. On the other hand, if the value of the counter variable C is 10 (has reached 10) at this time, the determination is satisfied, that is, the RFID circuit element To using one type of combination regarding the setting pattern of each communication setting element. It is considered that the wireless communication has been attempted 10 times, and the process proceeds to the next step S240.

  In the next step S240, the error rate E is obtained by multiplying the value of the failure variable F by 10. In other words, in this example, since the value of the failure variable F is the number of failures in 10 attempts of wireless communication, a value obtained by multiplying the value of the failure variable F by 10 indicates the error rate E in 100% notation as it is. In this way, the error rate E is obtained, and this flow is finished.

  FIG. 12 is a diagram illustrating a display example of a result screen 500 displayed on the display unit 201 of the operation terminal 200 when the communication setting element diagnosis process is performed and the communication setting element search is successful.

  On this result screen 500, the names of all communication setting elements are displayed in a list, and the setting patterns of the corresponding communication setting elements are displayed at the rear end positions of the names. In this example, the search result setting pattern is displayed for the bit rate and the modulation depth. However, as described above, other communication setting elements, that is, the standard, CRC reception, bandpass, and reception start are displayed. A specified pattern is displayed for time and reception gain.

  Then, the operator operates the “reflect to device” button (third operation means; lower center in FIG. 12) 501 on the result screen 500 to newly set the optimum setting pattern combination of each communication setting element. One communication condition is registered in the tag type registration table of FIG. 7 (the example shown in the figure shows the communication condition corresponding to the fourth tag type in FIG. 7).

In the above, step S155 and step S165 in the flow of FIG. 10 function as setting switching means described in each claim, and step S215 in the flow of FIG. 11 functions as information acquisition means. Further, step S145 in the flow of FIG. 10 functions as an optimum setting pattern determination unit .

  As described above, in this embodiment, the setting pattern of at least one communication setting element is sequentially switched (steps S155 and S165), and the communication antenna 101 of the RFID tag information communication apparatus 100 is set for each setting pattern. To the RFID circuit element To, and the tag ID reading process from the RFID circuit element To is performed (step S215). Then, the setting pattern (or combination thereof) of each communication setting element is searched so that the error rate E of the tag ID reading process is minimized, and the setting pattern (or combination thereof) having the lowest error rate E is Each communication setting element is determined as an optimum setting pattern (or a combination thereof, hereinafter the same as appropriate) (step S145).

  In this way, the optimum setting pattern is automatically determined by repeating the trial and error for each setting pattern of each communication setting element. Thus, even when there is an unknown number of RFID tag circuit elements To for each communication setting element, the operator can perform wireless communication with the RFID circuit element To without performing various setting inputs of the communication setting elements. The optimum setting pattern of communication setting elements on the device side can be obtained accurately and reliably. As a result, thereafter, information can be reliably read by wireless communication for the RFID circuit element To and the RFID tag circuit element To of the same type. In addition, the RFID tag circuit element To, which is already capable of reading information to some extent by the operator arbitrarily executing the above-described communication setting element diagnosis process, aims to further improve communication reliability and readjust the optimum setting pattern. It is also possible to perform.

  In this embodiment, in particular, the operator can perform a search for optimization by displaying, in the communication setting element designation screen 300, at least one communication setting element capable of sequentially switching setting patterns. It is possible to visually know in advance what the communication setting element is. As a result, when the communication setting element to be optimized is recognized, it can be confirmed whether or not it is included.

  In this embodiment, in particular, the communication setting element designation screen 300 is provided with a diagnosis target check box 301 that allows the operator to designate and input a communication setting element that is desired to be targeted. Thus, even if the operator does not input each communication setting element to be searched for optimization, if the operator enters a mark on the desired one among the communication setting elements displayed on the screen 300 (or the optimum setting) Therefore, it is sufficient if the communication setting element that is desired to be excluded from the search for the information is not filled in), so that it is possible to reduce the burden on the operator's operation and improve the convenience.

  In this embodiment, in particular, the result screen 500 displays a combination of optimum setting patterns determined by the communication setting element search process. As a result, not only the optimum setting pattern and combination of communication setting elements are determined, but also the operator is visually informed of what the obtained optimum setting pattern is, so that the operator can be surely recognized. be able to. Further, when the optimum setting pattern or the combination to the RFID circuit element To is not found from the device side, the RFID tag circuit element To is not supported by displaying an error screen (not shown). It is also possible to display the effect.

  In this embodiment, in particular, the combination of the optimum setting pattern of the obtained communication setting elements is stored in the tag type registration table of the storage unit CPM. When reading information about the RFID circuit element To, the combination of the optimum setting patterns is read from the storage unit CPM and used, so that information can be reliably read by wireless communication.

  In this embodiment, in particular, an operator can select and input whether or not to store the optimum setting pattern in the tag type registration table of the storage unit CPM by using the “apply device” button 501 on the result screen 500. As a result, the operator determines whether the optimum setting pattern of the communication setting elements and the combination thereof are stored in the tag type registration table of the storage unit CPM for future use, or not to be stored only for this time. Can choose. Therefore, the range of selection in use is expanded, and convenience is improved.

  In this embodiment, in particular, by sharing functions between the operation terminal 200 and the RFID tag communication apparatus 100, for example, by simply installing an application that realizes each control procedure and processing function on the operation terminal 200 side, It is sufficient to prepare a general-purpose device as the tag communication device 100, and the RFID tag communication system RS according to the present embodiment can be easily realized.

  The present invention is not limited to the configuration in which the operation terminal 200 and the RFID tag communication device 100 are separately configured and connected so as to be able to send and receive information as in the above-described embodiment, for example, a portable handy reader (particularly not shown). The configuration of the wireless tag communication device in which the CPU 203, the memory 204, the display unit 201, the operation unit 202, the large-capacity storage device 205, the high-frequency circuit 102, and the communication antenna 101 are integrated together (so-called all-in-one type). It is good. In this case, the CPU 203 can execute the procedure of step S155, step S165, step S210, and step S215 and the communication setting element search process of step S100.

  Thus, as described above, even when there is an unknown number of RFID tag circuit elements To for the communication setting elements, the operator can perform wireless communication with the RFID tag circuit elements To without performing various setting inputs of the communication setting elements. It is possible to accurately and reliably obtain the optimum setting pattern and the combination from the apparatus side when performing.

  Furthermore, by adopting an all-in-one type in which one RFID tag communication device includes each means, the configuration can be simplified as compared to the case where a system is constructed by combining a plurality of devices, and the system can be easily realized. Further, the entire movement can be easily performed when necessary.
