[Operation]
Next, the operation when the article storage device according to the first embodiment of the present invention performs control processing will be described with reference to the drawings. In the first embodiment of the present invention, the control method according to the first embodiment of the present invention is implemented by operating the article storage device 101. Therefore, the description of the control method according to the first embodiment of the present invention is replaced with the following description of the operation of the article storage device 101. In the following description, FIG. 3 will be referred to as appropriate.

  Moreover, in the sequence and flowchart shown below, the article storage apparatus 101 reads and executes a program including each step from the storage unit 16 shown in FIG. 3, for example. This program can be installed externally. The installed program is distributed in a state stored in a recording medium, for example.

  FIG. 5 is a flowchart that defines an operation procedure when the article storage device according to the first embodiment of the present invention performs the door opening process.

  Referring to FIG. 5, when the RFID multi-reader / writer 2 acquires a tag ID capable of opening and closing the key 7 in a state where the antenna unit 11 is in the outward position, the antenna unit 11 is in the inward position. Then, the key control unit 6 opens the key 7.

  More specifically, the box controller 4 refers to the tag information table 8 in order to prevent detection of unregistered RFID tags when the RFID multi-reader / writer 2 faces the outside of the door 17. Then, necessary radio control programs are selected and rearranged, and a radio control program execution list (door opening / closing) is created. The radio control program execution list (door opening / closing) created by the box controller 4 is delivered to the tag driver interpreter 13 via the command interpreter 12. (Step S1).

  Next, the tag driver interpreter 13 loads and executes the corresponding radio control program from the radio control program group 10 according to the radio control program execution list (door opening / closing) delivered from the box controller 4 (step S2). The tag ID is detected outside the housing 1 (step S3).

  Next, when the box controller 4 receives information indicating that the tag driver interpreter 13 has detected the tag ID via the command interpreter 12 (YES in step S3), the box controller 4 proceeds to an authentication process for the detected tag ID. (Step S4).

  The box controller 4 compares the detected tag ID with the registered tag ID 21 registered in the wireless control program execution list (door opening / closing) (step S4). The process proceeds to the unlocking process for the key 7 (step S5).

  Then, the box controller 4 refers to the wireless control program execution list, and when the detected tag ID is that of the door opening / closing tag (NO in step S5), the box controller 4 can only perform registration and release of the article management tag. Thus, the display / input unit 3 is controlled. Specifically, the display / input unit 3 displays “article tag registration / cancellation” and waits for an input from the user (step S6).

  On the other hand, the box controller 4 refers to the wireless control program execution list, and if the detected tag ID is that of the master tag (YES in step S5), registration and release of the door opening / closing tag, and article management The display / input unit 3 is controlled so that tag registration and cancellation can be performed. Specifically, the display / input unit 3 displays “door opening / closing tag registration / cancellation” and “article tag registration / cancellation” and waits for an input from the user (step S9).

  Next, after the processing by the display / input unit 3 is completed, the box controller 4 controls the reader / writer direction control unit 5 to rotate the RFID multi-reader / writer 2 so as to face the inside of the door 17, that is, the inside of the housing 1. (Step S7).

  Next, the box controller 4 controls the key control unit 6 to unlock the key 7 (step S8).

  On the other hand, if the box controller 4 cannot transition to this unlocking process (NO in step S3 or NO in step S4), the display / input unit 3 displays an error and ends the process (step S10). ).

  FIG. 6 is a flowchart that defines an operation procedure when the article storage device according to the first embodiment of the present invention performs the door closing process.

  Referring to FIG. 6, the RFID multi-reader / writer 2 is stored in the housing 1 when the key 7 is opened by the key control unit 6 and the key 7 is closed again in a state where the key 7 is closed. The tag ID of the RFID tag stored in the housing 1 is acquired by performing wireless communication with the RFID tag.

  Next, the box controller 4 updates the RFID tag management information, that is, the tag information table 8 based on the tag ID of the RFID tag stored in the housing 1 acquired by the RFID multi-reader / writer 2.

  Next, the antenna unit 11 is displaced to the outward position after the box controller 4 updates the management information.

  More specifically, when the door 17 is closed (step S11), the box controller 4 uses the RFID multi-reader / writer 2 facing the inside of the door 17 to perform wireless control corresponding to the unlocked RFID tag. A request for detecting the tag ID by executing the program is delivered to the tag driver interpreter 13 via the command interpreter 12. That is, the box controller 4 confirms whether or not the unlocked RFID tag is detected inside the housing 1. Thereby, it is possible to avoid the RFID tag that has been unlocked from being confined inside the housing 1 (step S12).

  Next, when the unlocked RFID tag is not detected (NO in step S13), the box controller 4 controls the key control unit 6 to lock the key 7 (step S14) and is lent out. The process transitions to a process for confirming the selected article (step S15).

  On the other hand, when the unlocked RFID tag is detected inside the housing 1 (YES in step S13), the box controller 4 causes the display / input unit 3 to display an error and ends the process. (Step S19).

  As a process for confirming the rented article, the box controller 4 refers to the tag information table 8 to perform selection and rearrangement of necessary radio control programs, and executes a radio control program execution list (article management). Create The created wireless control program execution list (article management) is delivered to the tag driver interpreter 13 via the command interpreter 12 (step S15).

  Next, the tag driver interpreter 13 loads and executes the corresponding radio control program from the radio control program group 10 in accordance with the radio control program execution list (article management) delivered from the box controller 4, and the registered tag An ID is designated, and an RFID tag having the tag ID is detected (step S16).

  Next, when the confirmation processing of the lent article is completed, the box controller 4 controls the reader / writer orientation control unit 5 to rotate the RFID multi-reader / writer 2 so as to face the outside of the door 17 (step S17). .

  Next, the box controller 4 controls the display / input unit 3 to end the display of “door opening / closing tag registration / cancellation” and “article management tag registration / cancellation” (step 18).

  FIG. 7 is a flowchart defining an operation procedure when the article storage device according to the first embodiment of the present invention performs door opening / closing tag registration processing.

  Referring to FIG. 7, registration of the door opening / closing tag is performed when the RFID multi-reader / writer 2 facing the inside of the door 17 detects the RFID tag to be registered.

  More specifically, first, the box controller 4 adds a radio control program that exists in the radio control program group 10 and is not registered in the tag information table in addition to the radio control program registered in the tag information table 8. By doing so, a radio control program execution list corresponding to the new registration is created. The created radio control program execution list is delivered to the tag driver interpreter 13 via the command interpreter 12 (step S21).

  Next, the tag driver interpreter 13 detects the tag ID inside the housing 1 in accordance with the wireless control program execution list delivered from the box controller 4 (step S22).

  Next, the box controller 4 detects the tag ID (YES in step S23), and the detected tag ID is not a master tag (NO in step S24), and is not registered in the tag information table 8. Sometimes (NO in step S25), in the tag information table 8, the detected tag ID is set as the registered tag ID 21, the radio control program detecting the tag ID is set as the program main body 22, and the frequency band used by the radio control program is set. Tag information whose type is frequency band type 23 is added (step S26).

  Next, the box controller 4 rearranges the tag information table 8 in the order of the frequency band types registered in order so that the radio control programs with the highest registration frequency are arranged in order (step S27).

  Furthermore, the box controller 4 rearranges in order of the radio control programs that are registered in the order so that radio frequency control programs with the highest registration frequency are arranged in order in each frequency band type (step S28).

  Next, when the rearrangement of the tag information table 8 is completed, the box controller 4 sets the registration type 24 of the added tag information as the door opening / closing tag and sets the rental tag ID 25 as the tag ID of the master tag (step S29).

  On the other hand, if the detected tag ID already exists in the tag information table 8 (YES in step S25) and is not a door opening / closing tag (NO in step S30), the box controller 4 determines the detected tag ID. The registration type 24 is updated to the door opening / closing tag, and the rental tag ID 25 is updated to the tag ID of the master tag (step S29).

  If the detected tag ID already exists in the tag information table 8 (YES in step S25) and is a door opening / closing tag (YES in step S30), the box controller 4 ends the process as it is.

  Further, when tag registration cannot be performed (NO in step S23 or YES in step S24), the box controller 4 causes the display / input unit 3 to display an error and ends the process (step S31).

  Here, the door opening / closing tag registration process will be supplementarily described using a specific example.

  FIG. 8 is a diagram showing a specific example of the tag information adding process in step S26 shown in FIG.

  Referring to FIG. 8, the detection tag 26 detected by the wireless control program has a registration tag ID 21, a program body 22, and a frequency band type 23 as tag information. Here, in the detection tag 26, the registration tag ID 21 is “tag ID 20”, the program main body 22 is “program 9”, and the frequency band type 23 is “2.4 GHz”. This tag information is added to the tag information table 8.

  This tag information is inserted, for example, between the last tag of the 2.4 GHz group, that is, between the tag ID 11 that is the 10th tag information in the tag information table 8 and the tag ID 0 that is the 11th tag information.

  FIG. 9 is a diagram showing a specific example of the sorting process based on the frequency band type of the tag information in step S27 shown in FIG.

  Referring to FIG. 9, the addition of the detection tag 26 results in a state in which the largest number of 2.4 GHz RFID tags are registered in the frequency band type 23.

  Therefore, the box controller 4 switches the order of the tag information of the frequency band type of 13 MHz and the tag information of 2.4 GHz so that the registration frequency is in descending order. Thereby, the detection efficiency of the RFID tag can be increased.

  FIG. 10 is a diagram showing a specific example of the sorting process for each frequency band type of the tag information in step S28 shown in FIG.

  Referring to FIG. 10, the box controller 4 changes the order of the tag information in the order in which each radio control program having a frequency band type of 2.4 GHz is registered in the program main body 22 in large numbers. Specifically, the order is program 9, program 7, and program 10. Thereby, the frequency | count of loading of a radio | wireless control program can be reduced.

  FIG. 11 is a flowchart that defines an operation procedure when the article storage device according to the first embodiment of the present invention performs an article management tag registration process.

  Referring to FIG. 11, the article management tag is also registered when the RFID multi-reader / writer 2 facing the inside of the door 17 detects the RFID tag to be registered.

  Since the basic sequence of the article management tag registration process is the same as the door opening / closing tag registration process, only the parts different from the flowchart shown in FIG. 7 will be described here.

  In the article management tag registration process, the box controller 4 uses the tag ID detected inside the housing 1 to unlock the RFID tag that has been unlocked to avoid being trapped inside the housing 1. If it is the same as the performed RFID tag (YES in step S45), registration of the tag ID is not permitted, an error display is performed on the display / input unit 3, and the process ends (step S53).

  The box controller 4 is registered in the tag information table 8 instead of the detected tag ID (NO in step S44), not the unlocked RFID tag (NO in step S45) ( If the tag is not an article management tag (NO in step S51), the registration type 24 of the detected tag ID is updated from the door opening / closing tag to the article management tag, and the rental tag ID 25 is cleared. The process is terminated (step S50). At this time, if there is an article that is being lent as a door opening / closing tag, that is, if the detected tag ID is registered in the rental tag ID 25 as a door opening / closing tag, the box controller 4 Since it is necessary to update the rental tag ID 25 in the information, the unlocked tag ID is set as the rental tag ID 25 (step S52).

  FIG. 12 is a flowchart that defines an operation procedure when the article storage device according to the first embodiment of the present invention performs the article management tag deregistration process.

  Referring to FIG. 12, the article management tag deregistration process is also performed when the RFID multi-reader / writer 2 facing the inside of the door 17 detects the RFID tag to be released.

  First, the box controller 4 creates a radio control program execution list based on the radio control programs registered in the tag information table 8 (step S61). The created radio control program execution list is delivered to the tag driver interpreter 13 via the command interpreter 12.

  Next, the tag driver interpreter 13 detects the tag ID inside the housing 1 in accordance with the radio control program execution list delivered from the box controller 4 (step S62).

  Next, when the tag ID is detected (YES in step S63), the box controller 4 determines that the detected tag ID is not a master tag (NO in step S64) in order to avoid the disappearance of the door opening / closing tag. And it is confirmed that the RFID tag is not unlocked (NO in step S65), and the process proceeds to the collation process with the tag information table 8 (step S66).

  Next, the box controller 4 is a case where the detected tag ID matches in the collation process with the tag information table 8, that is, the RFID tag registered in the tag information table 8 (YES in step S66). ) When the registration type 24 is a door opening / closing tag (YES in step S67), if there is an rented article, that is, there is tag information in which the detected tag ID is registered in the rental tag ID 25 as a door opening / closing tag. For example, the rental tag ID 25 of the tag information is changed to the unlocked tag ID (step S68).

  Next, when the detected registered tag ID can be canceled, the box controller 4 deletes the corresponding tag information from the tag information table 8 (step S69).

  Next, the box controller 4 rearranges the tag information table 8 in the order of the frequency band types registered in order so that the radio control programs with the highest registration frequency are arranged in order (step S70).

  Furthermore, the box controller 4 rearranges in order of the radio control programs registered in the order so that the radio control programs with the highest registration frequency are arranged in order in each frequency band type (step S71).

  On the other hand, when the tag controller cannot cancel the tag (NO in step S63, YES in step S64, or YES in step S65), the box / controller 4 causes the display / input unit 3 to display an error and ends the process (step S72). ).

  FIG. 13 is a flowchart that defines an operation procedure when the article storage device according to the first embodiment of the present invention creates a wireless control program execution list.

  Referring to FIG. 13, when the box controller 4 creates a door opening / closing execution list, that is, a radio control program execution list (door opening / closing) (YES in step S101), the registration type 24 is a master tag or a door opening / closing tag. Only use the wireless control program. That is, the box controller 4 extracts from the tag information table 8 the wireless control program whose registration type 24 is the master tag and the door opening / closing tag (step S102).

  Further, when the box controller 4 creates an execution list of article management, that is, a radio control program execution list (article management) (NO in step S101, YES in step S104), the registration type 24 is radio control of the article management tag. Use only programs. That is, the box controller 4 extracts from the tag information table 8 the wireless control program whose registration type 24 is the article management tag (step S105).

  Next, the box controller 4 rearranges the extracted radio control programs in the order of the frequency band types registered in order so that the radio control programs are arranged in order from the radio frequency control program having the highest registration frequency (step S103). Thereby, detection efficiency can be improved.

  Further, when creating another execution list (NO in step S101, NO in step S104), the box controller 4 extracts the wireless control program registered in the tag information table 8 (step S106), and the tag An unregistered radio control program that is not registered in the information table 8 but exists in the radio control program group 10 is added (step S107), and a registration tag execution list 30 is created.

  Here, supplementary explanation will be given by using a specific example for the process of creating the radio control program execution list.

  FIG. 14 is a diagram showing a specific example of the process of creating the wireless control program execution list (article management) in steps S105 and S103 shown in FIG.

  Referring to FIG. 14, the box controller 4 extracts the tag IDs 1, 6, 7, 8, 11, and 10 whose registration type 24 is the article management tag, and creates the article management tag list 27.

  Then, the box controller 4 arranges the extracted radio control programs in order of the frequency band types registered in order from the radio control program having the highest registration frequency, in this case, in the order of 13 MHz, 2.4 GHz, and 953 MHz. The rearrangement and article management tag execution list 28 is created. Thereby, the detection efficiency of the RFID tag can be increased.

  FIG. 15 is a diagram showing a specific example of registration tag execution list creation processing in steps S106 and S107 shown in FIG.

  Referring to FIG. 15, the wireless control program group 10 includes an unused program list 29. In this unused program list 29, there are programs 8 and 5 as radio control programs not registered in the tag information table 8.

  When registering these programs in the tag information table 8, the box controller 4 is registered in the tag information table 8 in order to correspond to the RFID tags detected by the radio control program not registered in the tag information table 8. The registered tag execution list 30 is created by adding the program 8 and the program 5 to the existing wireless control program.

  FIG. 16 is a flowchart that defines an operation procedure when the article storage device according to the first embodiment of the present invention performs a wireless control program execution process.

  Referring to FIG. 16, first, the execution list created by the process shown in FIG. 13 is delivered to tag driver interpreter 13. The tag driver interpreter 13 loads the wireless control program of the execution form from the wireless control program group 10 to the program memory according to the order of the execution list (step S111).

  Next, when the frequency band type used by the radio control program to be executed is changed (YES in step S112), the tag driver interpreter 13 switches to the antenna module of the corresponding frequency band in the antenna unit 11. Thereby, the frequency | count of frequency switching can be reduced (step S113).

  Next, when the tag driver is to detect the tag ID (NO in step S114), the tag driver interpreter 13 executes the program in the program memory according to the execution list without specifying the registered tag ID of the execution list (step S114). S115).

  Next, when the tag ID is detected (YES in step S116), the tag driver interpreter 13 stops the antenna unit 11 (step S118) and ends the detection process. The detected tag ID is returned as a result to the box controller 4 via the command interpreter 12.

  On the other hand, if the object management is the purpose (YES in step S114), the tag driver interpreter 13 designates the registered tag ID in the execution list and executes all the programs in the program memory (step S119).

  Next, the tag driver interpreter 13 is a case where a registered tag ID is detected (YES in step S120), and when a tag ID is set in the rental tag ID 25 of the registered tag ID (YES in step S123). Since the article corresponding to the registered tag ID has been returned to the article storage apparatus 101, the tag ID set in the rental tag ID 25 is cleared (S124).

  On the other hand, if the registered tag ID is not detected (NO in step S120) and the tag ID is not set in the rental tag ID 25 of the registered tag ID, the tag driver interpreter 13 is an article corresponding to the tag ID. Is lent out from the article storage device 101 (NO in step S121), and the unlocked tag ID is set in the rental tag ID 25 (step S122).

  Further, when there is an unexecuted program (YES in step S117), the tag driver interpreter 13 performs the same processing for the program (step S112), and when there is no unexecuted program (in step S117). NO), the antenna unit 11 is stopped (step S118), and the process is terminated.

  Here, the lending tag ID update process in the article management will be supplementarily described using a specific example.

  FIG. 17 is a diagram showing a specific example of the lending tag ID update process in step S122 shown in FIG.

  Referring to FIG. 17, when the key 17 is unlocked by the door opening / closing tag with the tag ID 4 and the article with the tag ID 6 is taken out from the article storage device 101, the tag driver interpreter 13 has the rental tag ID 25 with the tag ID 6. Is updated to tag ID 4 and is lent.

  FIG. 18 is a diagram showing a specific example of the lending tag ID update process in step S124 shown in FIG.

  Referring to FIG. 18, tag driver interpreter 13 detects tag ID 6 when an article with tag ID 6 is returned to article storage device 101. As a result, the tag driver interpreter 13 deletes the tag ID 4 set in the rental tag ID 25 of the tag ID 6 and returns it.
