These contents will be sequentially described in relation to other various apparatuses.

  As shown in FIG. 2, the card reader 98 is communicably connected to the management control device 70, and is used as a user information receiving unit that receives user specific information. Here, it is assumed that each user is given an IC card 99 in which a user ID that is specific information of the user is written, and the card reader 98 is incorporated in the electronic key issuing device 80. ing. Of course, the card reader 98 and the electronic key issuing device 80 may be separate. Then, a user who intends to use the present system holds the IC card 99 given in advance over the card reader 98, whereby the user ID assigned to the IC card is read by the card reader 98, and the user ID is It is accepted as user specifying information and is given to the management control device 70.

  The user information receiving unit that receives user specific information is not limited to the above example. In addition, the configuration may be such that the user identification code assigned to each user is received through a numeric keypad, etc., and user specific information is received using a biometric authentication device such as a fingerprint, vein, or voice. It may be a configuration.

  The management control device 70 includes a management control unit 71 having a CPU, a ROM, a RAM, etc., a computer main body having a storage unit 71a such as a hard disk device, etc., a display unit 72 such as a display device, and inputs such as a keyboard and a mouse. This is a general computer equipped with a unit 73, and executes a predetermined operation by a program stored in advance.

  The input unit 73 functions as a stored item specifying information receiving unit capable of receiving the specifying information of the storing unit 22 to be issued. The specific information of the stored items 10 is performed, for example, by inputting “ID No.” unique to each stored item 10. Here, “ID No.” and the unique identification code of the tag device 30 are described as being the same. However, as long as they are associated with each other, they may be different. In addition, when the name (for example, file name) of the stored item 10 and “ID No.” (or the identification code unique to the tag device 30) are managed in association with each other, the name of the stored item 10 is stored. May be received as the article specifying information. Moreover, you may make it select from the list | wrist etc. which were displayed on the display part 72, and specify the leaving object.

  The storage unit 71a is used to construct a management database based on the following various information, and functions as a management information storage unit.

  FIG. 7 shows an example of the management database stored in the storage unit 71a.

  The ID master file is a file in which “ID No.” unique to each stored item 10 is associated with a management level. The management level is set as a level that restricts the use of the user according to the confidentiality of each stored item 10. For example, a management level having a smaller value is set for the stored item 10 having higher confidentiality, and a management level having a larger value is set for the stored item 10 having lower confidentiality. The management level is used for operations according to the degree of confidentiality. This ID master file is appropriately created and updated by the operator of this system when the storage 10 is first stored. A specific operation example using the ID master file will be described later.

  In the shelf table, for each “shelf No.” that distinguishes each shelf 24, information that associates “ID No.”, which is the specific information of the stored item 10 stored in the shelf 24, and each “ID No.”. . ”Is stored as information in which the presence / absence of the extraction request flag is associated. The former information is used as shelf inventory information (stored inventory information) in which the inventory status of the storage 10 is associated with each shelf 24 which is each storage management area. When the latter information accepts the specific information of the stored object 10 to be delivered during the delivery operation of the stored object 10 to be described later, the retrieval request is made to “ID No.” which is the specific information of the stored object 10 to be delivered. This is information associated with the presence of a flag. The bookshelf table is newly created by communicating with each tag device 30 through the shelf control device 50 at the start of operation of the system, for example. Updated as appropriate. A shelf table update operation and an operation example will be described later.

  The log file is a file that stores a processing history and the like in this system. Here, the event that occurred in the present system and the time when the event occurred (or the time when the event was received by the management control device 70) are stored as associated information. Here, the following information regarding log information A to D is stored as an event.

  The storage unit 71a stores the tables shown in FIGS.

  The table shown in FIG. 8 shows a storage unit management table in which “storage unit No.” for specifying each storage unit 22 is associated with a management level.

  The table shown in FIG. 9 is the correspondence between the shelf and storage unit that associates “shelf No.” that specifies the shelf 24 that is the storage management area and “storage unit No.” that specifies each storage unit 22. Shows the table.

  Then, with reference to the storage unit management table and the shelf and storage unit association table, the management level of the storage unit 22 to which the shelf 24 in which the stored items 10 are stored belongs is specified, and the ID master file is referred to. Whether or not the storage 10 having a predetermined management level has been properly received in the storage unit 22 having the corresponding management level by identifying the management level associated with the storage 10 and comparing the management level. Can be determined. That is, the ID master file, the storage unit management table, the shelf level, and the storage unit association table are stored for each shelf 24 belonging to the storage unit 22 to which the stored item 10 having a predetermined management level is assigned the same management level. It can be said that it is information to be stored. In short, it is used as scheduled storage position information in which each stored item 10 is associated with information related to the shelf 24 (storage management area) in which the stored item 10 is to be stored.

  The tables shown in FIGS. 8 and 9 are created and set appropriately according to the contents stored by the operator of the system at the start of operation of the system, and are updated at appropriate timing.

  The table shown in FIG. 10 shows a user permission table in which a user ID that identifies a user is associated with a permission level indicating the contents that can be used by the user. The permission level indicates permission for a lower management level because of the same management level and confidentiality. For example, when the permission level is “5”, it indicates that the storage 10 having the management level “5” can be used. Further, for example, when the permission level is “2”, the storage 10 having the same management level “2” and lower “3-5” can be used.

  Then, by referring to the storage unit management table and the main table shown in FIG. 8, the storage unit 22 that can be used by the user can be determined. For example, the permission level corresponding to a predetermined user ID can be determined by referring to the user permission table. Then, by referring to the storage unit management table, “storage unit No.” having the same management level as the permission level and a lower management level can be specified according to the permission level. That is, the storage unit management table shown in FIG. 8 and the user permission table shown in FIG. 10 are used, information on availability of each storage unit 22 (depending on the correspondence between the permission level and the management level), and user identification information. It can be used as usage authority management information associated with a user ID. However, a table in which “storage unit No.” of each storage unit 20 is directly associated with each user ID may be used as the usage authority management information.

  Note that the table shown in FIG. 10 is created by appropriately setting according to the contents stored by the operator of the system at the time of starting the operation of the system, and deleting, adding, changing attributes, etc. When various circumstances arise, it is updated by the operator etc. as appropriate.

  The management control unit 71 manages the inventory status of each stored item 10 by using the tag device 30 while referring to various information stored in the storage unit 71a. In addition, when the user identification information is received by the card reader 98, the management control unit 71 issues an electronic key 90 through the electronic key issuing device 80 while referring to various information stored in the storage unit 71a. When the return of the electronic key 90 is accepted, a process of specifying the stored item 10 delivered by the user is executed while referring to the above information. These processes will be described in detail later.

  Note that the various processes performed by the management control unit 71 may be physically executed by a single control device, or may be performed in a distributed manner by a plurality of control units.

  Moreover, as shown in FIG.1 and FIG.2, the warehouse detection sensor 28 is provided corresponding to each shelf 24 (In FIG. 2, only one is shown for convenience of explanation.). The entering / exiting detection sensor 28 is configured by a reflection type or transmission type optical sensor or the like in which detection light is set so as to cross the front opening of each shelf 24. And in each shelf 24, when the stored article 10 with respect to the said shelf 24 is loaded / unloaded, the loading / unloading of the said stored article 10 is detected because the stored article 10 blocks detection light, etc., and the detection signal is managed. It is given to the control unit 71.

  The operation of each part of the stored matter management system will be described. For convenience of explanation, first, a procedure for using this system by a user will be schematically described.

  The user inputs the specific information of the stored item 10 desired to be delivered through the input unit 73 of the management control device 70. Thereafter, the user's specific information is input by holding the IC card 99 provided in advance over the card reader 98, and the electronic key 90 issued from the electronic key issuing device 80 is held and moved to the front of the storage shelf 20. . Since the light-emitting display part 42 of the storage shelf 20 storing the stored items 10 to be delivered is lit, the electronic key 90 is set on the locking / unlocking device 60 using this as a clue, and the door is unlocked. Open 23. Since the light emitting unit 55 of the shelf 24 storing the stored item 10 to be delivered is turned on, and the number of items 10 taken out from the shelf 24 is displayed on the removal number display unit 56, Is operated. Then, the tag device 30 attached to the stored item 10 to be delivered is turned on. The user issues one or more stored items 10 using the light emitted from the tag device 30 as a clue. When the storage of the stored item 10 on one shelf 24 is completed, the stored item 10 is extracted from the other shelf 24 in the same manner as described above. When the storage of the stored item 10 in the one storage unit 22 is completed, the electronic key 90 is taken out from the locking / unlocking device 60. And if necessary, the stored item 10 is delivered from the other storage unit 22 in the same manner as described above. When the storage of the stored items 10 is completed from each storage shelf 20, the electronic key 90 is returned to the electronic key issuing device 80. Thereby, the delivery of the stored item 10 is completed.

  FIG. 11 is a flowchart showing the operation of the tag device 30.

  First, in the initial state, the tag device 30 is in a sleep state with relatively low power consumption. In step S1, when the optical signal from the shelf control device 50 is received through the light receiving unit 31, the tag control unit 32 wakes up, and then proceeds to step S2.

  In step S2, the tag control unit 32 determines whether or not an ID response command is included in the received optical signal. If it is determined that the ID reply command is included, the process proceeds to step S7.

  In step S <b> 7, the tag control unit 32 executes an ID response process of transmitting an optical signal including its own identification code through the communication light emitting unit 34. Note that when performing an ID response, it is preferable to avoid collision of signals transmitted from the plurality of tag devices 30 by appropriately shifting the variation timing. Thereafter, the process is terminated and the process shifts to the sleep state.

  On the other hand, if it is determined in step S2 that the ID reply command is not included, the process proceeds to step S3.

  In step S <b> 3, the tag control unit 32 determines whether “ID No.” included in the received optical signal matches its own identification code. If it is determined that there is a mismatch, the process is terminated and the process shifts to the sleep mode. On the other hand, if it is determined that they match, the process proceeds to step S4.

  In step S4, the tag control unit 32 performs a response operation of outputting a response light signal through the communication light emitting unit 34, and then proceeds to step S5.

  In step S5, the tag control unit 32 determines whether or not a light emission command is included in the received optical signal. If it is determined that the light emission command is not included, the process ends and the process shifts to the sleep mode. If it is determined that the issue command is included, the process proceeds to step S6.

  In step S <b> 6, the tag control unit 32 performs a notification operation for lighting the notification light emitting unit 35 for a certain period of time. Thereafter, the process is terminated and the process shifts to the sleep mode.

  FIG. 12 is a flowchart showing the delivery request acceptance operation of the management control device 70 when the user inputs the specific information of the stored item 10 that the user wants to leave.

  First, in step S <b> 11, the management control unit 71 accepts a delivery request ID (that is, “ID No.”) as specific information of the stored item 10 through the input unit 73.

  Next, in step S12, the management control unit 71 refers to the shelf number (ie, “shelf No.”) in which the storage item 10 having “ID No.” received with reference to the shelf table (see FIG. 7) is stored. ). And the management control part 71 communicates with the tag apparatus 30 attached to the storage thing 10 stored in the said shelf 24 through the shelf control apparatus 50 of the specified shelf number, and the presence or absence of inventory is confirmed. Check. More specifically, the management control unit 71 transmits an optical signal including the specified “ID No.” through the shelf control device 50 in the shelf 24.

  In next step S <b> 13, the management control unit 71 determines whether or not there is a response from the tag device 30. That is, after the step S12, the tag device 30 having an identification code that matches the identified “ID No.” responds, and the presence / absence of inventory in the shelf 24 is confirmed by the presence / absence of this response. If there is a response, the process proceeds to step S14.

  In step S <b> 14, the management control unit 71 registers an extraction request flag in the shelf table as the specific information of the stored item 10 that is accepted through the input unit 73 (see FIG. 7).

  At this time, as the log information A, information (for example, “ID No.”, etc.) relating to the specific information of the stored item 10 to be issued is generated. Processing based on this log information A will be described later.

  In the next step S15, the management control unit 71 causes the light emitting display unit 42 to emit light through the rack control unit 40 of the storage shelf 20 in which the stored item 10 is stored. Thereafter, the process ends.

  On the other hand, if the management control unit 71 determines in step S13 that there is no response from the tag device 30, the process proceeds to step S16.

  In step S <b> 16, the management control unit 71 communicates with the tag device 30 attached to the storage 10 stored in each shelf 24 through the shelf control devices 50 of all the shelves 24, and In the same way as above, check for stock.

  In the next step S17, the management control unit 71 determines whether or not there is a response from the tag device 30, and if it is determined that there is a response, the process proceeds to step S18, and if it is determined that there is no response, the process proceeds to step S19.

  In step S <b> 18, the management control unit 71 specifies the shelf number to which the tag device 30 that has responded belongs by specifying which shelf control device 50 has received the response signal from the tag device 30. Based on the specified result, the inventory location of the shelf table is updated so that the inventory position of the stored item 10 is correct. The management control unit 71 identifies each shelf control device 50 using, for example, an identifier given in advance to each shelf control device 50. Thereafter, the process proceeds to step S14, and thereafter, the same processing as described above is executed.

  If it is determined in step S17 that there is no response, the process proceeds to step S19, and the inventory information is updated so that the “ID No.” of the specified stored item 10 is deleted from the shelf table.

  Thereafter, the process proceeds to step S20, a message indicating that the product is not in stock, such as “absent, taking out”, is displayed, and the process is terminated.

  In addition, when there are a plurality of outgoing objects, in step S11, “ID No.” of the plurality of stored items 10 may be received collectively or sequentially.

  Thus, the shelf table at the time when the exit request acceptance process is completed is held in the same content until the electronic key 90 is issued and further the electronic key 90 is returned, and the electronic key 90 is used in subsequent processing. It is provided as shelf inventory information at the start time and specific information of stored items to be issued.

  FIG. 13 is a flowchart showing the electronic key 90 issuing process by the management control unit 71.

  In issuing the electronic key 90, the user holds the IC card 99 over the card reader 88. Then, in step S1, the management control unit 71 reads the user ID of the IC card 99 through the card reader 88, and proceeds to the next step S22.

  In the next step S22, the management control unit 71 determines whether or not the user ID is valid. This determination is made based on, for example, whether or not the corresponding user ID is registered in the use permission table shown in FIG. If it is determined to be invalid, the process ends. If it is determined to be valid, the process proceeds to step S23.

  In step S <b> 23, the management control unit 71 writes the usage authority information to the electronic key 90 through the electronic key issuing device 80. As described above, the usage authority information refers to the storage unit management table shown in FIG. 8 and the user permission table shown in FIG. It is written as information specifying.

  In the next step S24, the management control unit 71 releases the lock of the electronic key 90 by the electronic key issuing device 80. At this time, the management control unit 71 generates, as the log information B, information including a user ID that identifies the user. The information relating to the log information B is information relating to the user and the issue time of the electronic key 90 for the user, and is provided as issue information of the electronic key 90 obtained through the operation of the electronic key issuing device 80. The processing based on this log information B will be described in detail later.

  Then, the issuing process ends.

  In this way, the electronic key 90 is issued through the electronic key issuing device 80 in response to the reception of the user's specific information, and the user writes the usage authority information specifying the usable “storage unit No.”. The stored electronic key 90 can be taken out from the electronic key issuing device 80 and held.

  FIG. 14 is a flowchart showing the operation of the locking / unlocking device 60.

  In step S1, the lock-side control device 64 detects whether or not the electronic key 90 is set. If the electronic key 90 is not detected, the process ends. If the electronic key 90 is detected, the lock-side control device 64 ends the process. Proceed to S32.

  In step S32, the lock control unit 65 reads the usage authority information from the electronic key 90 through the communication terminal 65a, and proceeds to the next step S33.

  In step S33, the lock side control unit 65 determines whether or not the authentication is successful based on the read usage authority information. Here, the lock side control unit 65 includes its own “storage unit No.” stored in the lock side storage unit 66 in the available “storage unit No.” included in the read usage authority information. If it is included, it is determined that the authentication has passed, and if it is not included, it is determined that the authentication has failed.

  That is, in steps S32 and S32, the locking / unlocking device 60 communicates with the electronic key 90 and performs an authentication operation based on the usage authority information. However, the process related to authentication may be performed by either the locking / unlocking device 60 or the electronic key 90. For example, the lock-side control unit 65 gives its own “storage unit No.” to the electronic key 90 side, determines whether the authentication is successful, and gives the determination result to the locking / unlocking device 60 side. It may be. That is, the authentication operation may be a process performed by the locking / unlocking device 60 and the electronic key 90 through mutual communication.

  If it is determined in step S33 that the authentication has failed, the lock control unit 65 ends the process and maintains the lock device 61 in the locked state. On the other hand, if it is determined in step S33 that the authentication has passed, the lock control unit 65 proceeds to step S34, switches the lock device 61 to the unlocked state, and then proceeds to step S35.

  In step S <b> 35, the lock side control unit 65 writes the “storage unit No.” of the unlocked storage unit 24 and the operation history such as the unlocked time into the key side storage unit 93 of the electronic key 90. Thereafter, the process ends.

  The operation of the management control device 70 after issuing the electronic key 90 will be described. After the electronic key 90 is issued, the management control device 70 performs the monitoring process of the instruction unit 54 and the monitoring process of the entering / exiting detection sensor 28 of each shelf control device 50.

  FIG. 15 is a flowchart showing the monitoring process of the instruction unit 54.

  That is, in step S41, the management control unit 71 of the management control device 70 monitors whether or not there is an operation input to the instruction unit 54 of each shelf control device 50. If the instruction unit 54 of the instruction unit 54 is not turned on, the process ends and returns to the monitoring state. If the instruction unit 54 is turned on, the process proceeds to step S42.

  In step S42, the management control unit 71 determines whether the take-out request ID exists in the shelf 24 corresponding to the turned on instruction unit 54. Here, the management control unit 71 refers to the shelf table to determine whether “ID No.” in which the extraction request flag is registered in the “shelf No.” corresponding to the turned on instruction unit 54. If it is determined that the extraction request ID does not exist, the process ends. If it is determined that the extraction request ID exists, the process proceeds to step S43.

  In step S43, the management control unit 71 transmits an optical signal including “ID No.” in which the extraction request flag is registered through the corresponding shelf control device 50 in the shelf 24 corresponding to the turned on instruction unit 54. To do. Then, the tag device 30 having an identification code that matches the “ID No.” responds and performs a notification operation by light emission. Thereby, the user can recognize the existence location and can easily take out the desired storage item 10. In step S43, the management control unit 71 generates, as log information C, information including “ID No.” of the tag device 30 that has performed the notification operation with a response. The log information C includes operation information of the tag device 30 obtained by the shelf control device 50 communicating with the tag device 30. Processing based on this log information C will be described later.

  Thereafter, the management control unit 71 ends this process.

  FIG. 16 is a flowchart showing the monitoring process of the entry / exit detection sensor 28.

  That is, in step S45, the management control unit 71 monitors whether or not the loading / unloading detection sensor 28 provided corresponding to each shelf 24 is turned on. Here, if any of the entry / exit detection sensors 28 is not turned on, the process is terminated and the monitoring state is restored. On the other hand, when the user enters / exits the stored item 10 from any one of the shelves 24, the entry / exit is detected, and the entry / exit detection sensor 28 is turned on. Then, based on the detection result, the management control unit 71 determines that the entry / exit detection sensor 28 is turned on, and proceeds to step S46. Note that the management control unit 71 determines which shelf 24 corresponds to, for example, an identifier given in advance to each warehouse detection sensor 28.

  In step S46, the management control unit 71 registers the shelf 24 corresponding to the turned-in / out detection sensor 28 in the use shelf number list and stores it in the storage unit 71a or the like. Then, the management control unit 71 ends the process. The use shelf number list may be temporarily created in the work area of the memory or may be created in the storage unit 71a.

  The processes shown in FIGS. 15 and 16 are always performed as a monitoring process until the return of the electronic key 90 is accepted.

  FIG. 17 is a flowchart showing return acceptance processing of the electronic key 90 by the management control device 70.

  That is, the management control unit 71 determines whether or not the electronic key 90 is returned through the electronic key issuing device 80. If the return of the electronic key 90 is not detected, the management control unit 71 ends the process. If the return of the electronic key 90 is detected, the management control unit 71 proceeds to step S52.

  In step S52, the management control unit 71 locks the electronic key 90 by the electronic key issuing device 80 so that the electronic key 90 cannot be taken out, and proceeds to the next step S53.

  In step S <b> 53, the management control unit 71 reads an operation history from the electronic key 90 through the electronic key issuing device 80. In step S <b> 53, the management control unit 71 generates an operation history and return information of the electronic key 90 as the log information D. That is, the log information D includes return information of the electronic key 90 and information related to the authentication operation between the electronic key 90 and the locking / unlocking device 60. Processing based on this log information D will be described later.

  Then, the management control unit 71 ends the return acceptance process.

  FIG. 18 is a flowchart showing the processing of the management control device 70 after the log information A to D is generated.

  That is, the management control unit 71 of the management control device 70 executes the following as a process for collecting the log information A to D generated in each of the above processes and performing the storage management.

  First, in step S61, when the management control unit 71 receives the generated event information regarding the log information A to D in each of the above processes, the management control unit 71 proceeds to step S62.

  In step S <b> 62, the management control unit 71 determines whether or not the electronic key 90 is returned through the electronic key issuing device 80. That is, it is determined whether or not the occurrence event is related to the log information D. If it is determined that the electronic key 90 is not returned, the process proceeds to step S63.

  In step S63, the management control unit 71 registers an occurrence event (here, an event related to any of the log information A to C) in the log file.

  On the other hand, if it is determined in step S62 that the electronic key 90 has been returned, the process proceeds to step S64. In step S64, the management control unit 71 refers to the used shelf number list (see FIG. 16), identifies the used “shelf level”, and controls the shelf level in each of the used shelf levels 24. The inventory confirmation is performed through the device 50, and a shelf primary table including the inventory status of the storage 10 for each shelf 24 is generated as primary storage inventory information. More specifically, the management control unit 71 transmits an optical signal including an ID response command to each tag device 30 through the shelf control device 50 in the used shelf 24. Then, each tag device 30 transmits an optical signal including its own identification code. The management control unit 71 receives the identification code of each tag device 30 through the shelf control device 50 to identify the identification code corresponding to the stored item 10 stored in the shelf 24. Then, based on the identification result, a shelf primary table (stored inventory primary information) in which the identification codes read corresponding to the stored storage 10 are listed is generated for each shelf 24 used. . The shelf primary table may be stored in the storage unit 71 a or may be temporarily generated in a work area memory in the management control unit 71. The entry / exit detection sensor 28 may be omitted, and the shelf primary table may be generated for all the shelves 24 regardless of whether or not each shelf 24 is used. Thereafter, the process proceeds to step S65.

  In step S65, the management control unit 71 compares the shelf inventory information included in the shelf table with the shelf primary table. Based on the comparison result, “ID No.” corresponding to the stored item 10 issued by the user is specified. Note that since the shelf table is not updated after the electronic key 90 is issued, the shelf table used here is also the shelf table at the time when the use of the electronic key 90 is started.

  Then, the management control unit 71 compares the shelf inventory information included in the shelf table with the primary shelf table, and the set of “ID No.” registered in the primary shelf table and “ID No.” registered in the shelf inventory information. One of the following three processes is sequentially executed for each of “ID No.” that is an element of the union of the sets.

  First, in step S65, the management control unit 71 maintains the shelf table including the shelf inventory information as it is for “ID No.” that is determined to be registered in both the shelf primary table and the shelf inventory information. Then, the process proceeds to step S63. In step S63, the log information D, which is an occurrence event, is registered in the log file, and the process ends.

  Such processing is performed for “ID No.” relating to the stored item 10 that has not been actually entered or exited.

  In step S64, when the management control unit 71 determines that “ID No.” exists in the shelf primary table and does not exist in the shelf inventory information, the management control unit 71 performs step S66 for the “ID No.”. Proceed to and process. In step S66, the management control unit 71 compares the management levels. That is, the management control unit 71 identifies “ID No.” that exists in the shelf primary table and does not exist in the shelf inventory schedule information, and refers to the ID master file (see FIG. 7). The management level of the stored item corresponding to “ID No.” is specified. Further, the management control unit 71 refers to the shelf primary table, identifies “storage unit No.” in which the identified “ID No.” is stored, and refers to the storage unit management table (see FIG. 8). Then, the management level of the “storage unit No.” is specified. And the management control part 71 compares the specified management level, and when both correspond, it progresses to step S67 as a fitting receipt.

  In step S67, the management control unit 71 registers “ID No.”, which exists in the shelf primary table and does not exist in the shelf inventory schedule information, as shelf inventory information in the shelf table.

  Thereafter, the process proceeds to step S63, where the log information D, which is an occurrence event, is registered in the log file, and the process ends.

  On the other hand, if the management control unit 71 determines in step S66 that the specified management levels do not match, the process proceeds to step S68 as a non-conforming warehousing.

  In step S68, the management control unit 71 registers “ID No.”, which exists in the shelf primary table and does not exist in the shelf inventory schedule information, as shelf inventory information in the shelf table. Moreover, the management control part 71 outputs the alerting | reporting signal which alert | reports the improper warehousing that the management level of the storage part 22 and the management level of the storage thing 10 do not correspond, and issues an improper warehousing. For example, the notification is performed when a sounding body such as a buzzer emits sound. In addition, it may be performed by displaying the fact on the display unit 72.

  Thereafter, the process proceeds to step S63, where the log information D, which is an occurrence event, is registered in the log file, and the process ends.

  Such processing is performed for “ID No.” related to the stored item 10 received by the user.

  In step S64, when the management control unit 71 determines that “ID No.” that does not exist in the shelf primary table and exists in the shelf inventory information exists, the step is performed for the “ID No.”. Processing proceeds to S69.

  In step S69, the management control unit 71 refers to the take-out request flag registered in the shelf table, and makes an extraction request for “ID No.” that does not exist in the shelf primary table and exists in the shelf inventory information. Judge whether or not Here, if it is determined that the removal is requested, the process proceeds to step S70. This step S69 is based on the shelf inventory information included in the shelf table, the take-out request flag that is the specific information of the stored items to be issued, and the stored items other than the stored items 10 to be issued based on the primary shelf table. It can be said that it has been judged whether or not has been issued.

  In step S70, the management control unit 71 assumes that the “ID No.” that is not present in the shelf primary table and is present in the shelf inventory information is properly taken out, and is included in the shelf table. Remove from information.

  Thereafter, the process proceeds to step S63, where the log information D, which is an occurrence event, is registered in the log file, and the process ends.

  On the other hand, if it is determined in step S69 that the removal is not requested, the process proceeds to step S71.

  In step S71, the management control unit 71 outputs a notification signal for notifying unauthorized shipment, thereby issuing an unauthorized removal. That is, when it is determined that something other than the stored object 10 to be delivered has been delivered, the unauthorized delivery is notified in this step S71. For example, the notification is performed when a sounding body such as a buzzer emits sound. In addition, it may be performed by displaying the fact on the display unit 72.

  Thereafter, the process proceeds to step S63, where the log information D, which is an occurrence event, is registered in the log file, and the process ends.

  In step S71, the user who has illegally taken out information can be specified by referring to the user specifying information included in the log information B registered in the log file.

  This process is a process performed for “ID No.” related to the stored item issued by the user.

  The take-out request flag registered in the shelf table is deleted at an appropriate timing until the next take-out operation.

  According to the stored matter management system configured as described above, the management control unit 71 communicates with the tag device 30 through the shelf control device 50 by accepting the return of the electronic key 90 issued to a specific user. This is done to generate shelf position time information including the inventory status of the stored items 10 for each shelf level 24. Then, based on the shelf primary table and the shelf table including the shelf inventory information at the time when the electronic key 90 starts to be used, the management control unit 71 sets “ID No. ”Is specified. For this reason, it aims at enabling it to manage which stored thing 10 was delivered for every user.

  In addition, when it is determined that a stored item 10 other than the stored item 10 to be issued specified through the input unit 73 has been issued, the unauthorized issue is notified, so that the unauthorized issue can be recognized.

  In addition, since the management control unit 71 updates the shelf table so as to delete the “IDNo.” For “IDNo.” Corresponding to the stored item 10 that has been properly extracted with the removal request flag registered, The shelf inventory information included in the shelf table can be sequentially updated more accurately according to the actual delivery situation.

  When the user ID is received through the card reader 98, the management control unit 71 writes the usage authority information corresponding to the user ID in the electronic key 90 and issues the electronic key 90. Then, the electronic key 90 and the locking / unlocking device 60 communicate to perform an authentication operation based on the usage authority information, and the locking / unlocking device 60 switches to the unlocked state. For this reason, only the authorized storage 10 can be used for each user, and the operation according to the confidentiality of the storage 10 becomes possible.

  In addition, the management control unit 71 identifies the shelf 24 on which the stored item 10 is actually loaded / unloaded based on the output result from the loading / unloading detection sensor 28, and the shelf control device in the identified shelf 24. The shelf primary table is generated by communicating with the tag device 30 through 50. For this reason, it is possible to quickly generate the shelf primary table while reducing the operation opportunity of the tag device 30.

  In addition, the management control unit 71 compares the management level related to the stored item 10 received with the management level of the storage unit 22 in which the stored item 10 is stored. The table is updated, and if the two do not match, a notification signal is output and an inappropriate warehousing is issued. Accordingly, when it is determined that the stored item 10 that has been received has not been stored in the regular storage unit 22 (that is, the storage position) having the corresponding management level, an inappropriate storage can be notified. Thereby, it is possible to prompt the storage 10 to be stored in the regular storage unit 22 (position) having the corresponding management level.

  In addition, since the management control unit 71 registers the log information A to D in the log file and stores them in the storage unit 71a, information (log information A) and tag related to the specific information of the stored item 10 that is a delivery mode Operation information of apparatus 30 (log information C), issuance information or return information of electronic key 90 (log information B, log information D), information on authentication operation between electronic key 90 and locking / unlocking apparatus 60 (log information D) Etc. can be managed as history information.
