Description

  The present invention relates to storage and take-out management technology for important articles, and in particular, ID identification of storage management objects using IC tags, and identification IDs using IC tags and IC tags for alternative storage items indicating that they are being taken out. In the storage location having ID data for identifying the storage location and having the function of wirelessly reading the ID data stored in the IC tag, the status of each ID data that can be read is constantly monitored, thereby changing the storage status. The present invention relates to a technology that is effective when applied to an article management system that realizes finer management by automatically grasping and quickly detecting and alarming an abnormal state.

  For example, in the article storage and take-out management technology, when taking out an article to be managed, bring it to a lending counter provided at the facility, and associate the ID for identifying the take-out with the ID of the take-out at that location. There is a first method for managing the status of the take-out person and the managed article to be taken out by registering in the system. In such a system, there is Patent Document 1 or the like as a technique for checking article take-out management at the entrance of a building or the entrance of a room.

  Further, there is a second method that uses the shelf number corresponding to the storage location and the arrangement order of the management target items as information on the location where the management target items are stored. In such a system, as a technique for guiding the position of a shelf as a storage location, there is Patent Document 2 and the like.

Further, as a method of storing another article as an alternative to the management target article to be taken out, there is a third system that uses the alternative article in which the management target article information is recorded.
JP 2005-301331 A JP 2006-27768 A

  By the way, in the storage and take-out management technology for articles as described above, in the first method, after taking out the management target article from the storage location and bringing it to the rental counter, a particularly large storage facility and a large number of management targets are provided. For example, when the goods are taken out and brought together to the lending counter, there will be times when the location of the goods to be managed is temporarily unknown, and customer information, personal information, and confidential business information that require particularly strict management There was a problem in storage management.

  In the second method, the storage location is fixed when the location information is managed by using, as location information, information that depends on the storage facility, such as a shelf number, or the arrangement order of the management target items. In other words, storage, take-out, and return must be performed in a fixed place, and there is a problem that impairs convenience for both users and administrators.

  Further, even in the third method, there is a problem that only a predetermined substitute can be placed in the method of placing a predetermined substitute corresponding to the management target article. In addition, when the system that records the correspondence between the take-out person and the managed article is in an emergency such as a system failure, the managed article corresponding to the substitute item stored as the actual product in the storage location cannot be confirmed. Even if the above information is stored, there is a problem that the take-out person who is taking out the management target item cannot be identified, and the inquiry destination in an emergency is not known.

  Therefore, the object of the present invention is to solve these problems, and it becomes possible for the administrator to quickly grasp when there is an unknown time even for a short time, and for the user without worrying about the storage location. It is an object of the present invention to provide an article management technique that can improve convenience and can make an inquiry destination in an emergency possible.

  The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

  Of the inventions disclosed in the present application, the outline of typical ones will be briefly described as follows.

  In the present invention, in addition to the identification ID data A of the article to be managed, the identification ID data B of the take-out proof article to be stored instead at the time of take-out, and the place where the place can be stored is attached to the article storage place. By always automatically reading three types of ID data of the identification ID data C with the wireless ID data reader 1, the storage state is automatically recorded and updated each time an article is taken out or placed, By detecting that ID data A and ID data B cannot be read during the elapsed time and issuing an alarm, it is possible for the administrator to quickly grasp if there is an unknown time even for a short time. .

  In addition, the IC tag c storing the location identification ID data C can be identified as data as it is without worrying about the shelf number or the order of arrangement, and when the managed article is taken out. Even when returned to a different location, the correspondence with the new location identification ID data C is automatically recorded, so that it can be used without worrying about the storage location, and the convenience of the user is improved.

  In addition, the identification ID data B of the carry-out proof article placed as an alternative to the managed article defines only the correspondence with the information related to the take-out person, so that the carry-out proof article can be substituted for any managed article. In case of a system failure, it is possible to obtain information related to the taker by reading the ID of the carry-out proof article stored in the storage location as an actual item. Make sure you know the destination.

  Among the inventions disclosed in the present application, effects obtained by typical ones will be briefly described as follows.

  According to the present invention, it is possible for the administrator to quickly grasp when there is an unknown time even in a short time, and it is possible for the user to improve convenience without worrying about the storage location, Furthermore, it becomes possible to know the contact information in an emergency.

The managed article / carry-out certificate article correspondence determination unit (113) refers to the managed article ID / location identification ID correspondence status table 1 (105) and the withdrawal certification item ID / location identification ID correspondence status table 2 (106). Then, the correspondence between the management target article and the carry-out certificate article stored instead is determined, and the management target article ID / export certificate ID correspondence state table 3 (107) is updated. For example, the management object identification ID data A (during taking out) “3591” is updated to the taking out identification identification data B (in storage) “55754”, and the others are as shown in FIG.

  9 shows whether one or a plurality of ID data read by the ID data reading device 1 (207) is the management object identification ID data A or the take-out identification identification data B, and the storage location identification ID data. It is an example of the processing flow of the ID data type discrimination | determination part (111) which discriminate | determines whether it is C. FIG.

  In step (901), ID data is read and acquired by the ID data reading device 1 (207), the management object ID definition table 1 (101), the take-out certificate ID definition table 2 (102), and the location identification ID definition The ID data value registered in each definition table of the table 3 (103) is compared with the read ID data value.

  In step (905), date and time data read from the ID data reader 1 (207) is acquired in parallel with step (901). The date / time data is recorded as reading date / time data held in the state database (104), and is based on a predetermined reading timing preset in the ID data reading device 1 (207).

  In step (902), when the read ID data value matches the managed object ID data A registered in the managed object ID definition table 1 (101), the read ID data value is the ID data of the managed object. Judge.

  In step (903), if the read ID data value matches the carried-out article ID data B registered in the carried-out article ID definition table 2 (102), the read ID data value is the carried-out article. ID data.

  In step (904), if the read ID data value matches the location identification ID data C registered in the location identification ID definition table 3 (103), the read ID data value is determined to be location identification ID data. To do.

  In step (906), the type of ID data determined in steps (902), (903), and (904) and the read date / time data acquired in step (905) are collectively stored in the state database (104) with the read date / time as a key. Generate and record the record.

  FIG. 10 shows a location / article correspondence discriminating section (112) for discriminating in which location the article to be managed or in which place the export proof article is stored from the data contents recorded in the state database (104). It is an example of the processing flow.

  In step (1001), the management object identification ID data A, the take-out certificate identification ID data B, and the storage location identification ID data C recorded in the state database (104) for each reading date and time are displayed on the time axis for each reading date and time. Compare and refer to the order of. The reference timing may be independent of the ID data reading timing of the ID data reading device 1 (207), but is referenced at a timing equivalent to the reading timing in terms of time.

  In step (1002), the storage location identification ID data C recorded at the next reading timing, that is, the reading date T2, is the value of the storage location identification ID data C recorded at the reading date T1 in step (1001). The value of is detected. This means that something has been placed in the storage location. The storage location identification ID data A and the take-out certificate ID data B at the reading date T2 are compared with the reading dates T1 and T2, and the storage location identification recorded at the reading date T2 is not recorded at the reading date T1. ID data A and carry-out article ID data B are discriminated. This ID data is the ID data of the article newly placed at the location indicated by the storage location identification ID data C.

  When the newly placed article is a management target article, in step (1003), the storage location identification ID data C that disappeared at T2 and the newly recorded management target article ID data A value are used as the management target article ID. Recording and updating in the location identification ID correspondence status table 1 (105). If the newly placed article is a carry-out proof article, in step (1004), the storage location identification ID data C that disappeared at T2 and the newly recorded value of the carry-out proof article ID data B are taken out. Recorded and updated in the article ID / location identification ID correspondence state table 2 (106).

  FIG. 11 is an example of a processing flow of the management object / carrying-out proof article correspondence determining unit (113) that generates correspondence information between the taken-out management target article and the proof article stored instead. .

  In the present invention, the combination of the management target article and the carry-out certificate article stored instead of the article is realized without taking a predetermined correspondence in advance. Correspondence is determined through the location identification ID data C for the combination of the dynamically changing managed object item and the carry-out certificate item stored instead.

  In step (1101), with reference to the managed object ID / location identification ID correspondence status table 1 (105) and the carry-out certificate ID / location identification ID correspondence status table 2 (106), the same location identification ID data C is stored. Corresponding management object ID and location identification ID are detected.

  In step (1102), when there is the same location identification ID data, the management subject article ID and the location identification ID are recorded as corresponding ID data in the management subject article ID / bill certificate ID correspondence state table 3 (107). ,Update.

  FIG. 12 is an example of a processing flow of the elapsed time discriminating unit (114) that issues an alarm when a predetermined time has passed in a state where the management target article is just taken out from the storage location.

  In step (1201), the status database (104) is constantly monitored, and the ID data value for each reading date and time recorded therein is referred to.

  In step (1202), the management target article ID data A that is not recorded at the next reading timing, that is, the reading date T4 is detected based on the value of the management target article ID data A recorded at a certain reading date T3.

  In step (1203), reference to the managed object ID / bill certificate ID corresponding state table 3 (107) is always started. The fact that the management subject article ID data B corresponding to the management subject article ID data A that is not recorded at the reading date and time T4 is recorded in the management subject article ID / takeout certification article ID correspondence state table 3 (107). This means that a proof item is placed in place of the managed item. On the contrary, being left unrecorded means that the managed article has only been taken out. The elapsed time from the reading date / time T4 until it is recorded in the management object article ID / bill certificate ID correspondence state table 3 (107) is counted.

  In step (1204), monitoring of the state database (104) is continued in parallel with step (1203). When the management target article ID data A that is no longer recorded at the reading date and time T4 is recorded again in the status database (104), this means that the management target article taken out at the reading date and time T4 is returned to the storage location again. The elapsed time from the reading date / time T4 until the management target article ID data A is recorded again in the state database (104) is counted.

  In step (1205), it is determined whether any of the elapsed times counted in step (1203) and step (1204) has passed a predetermined elapsed time.

  When the elapsed time has passed, in step (1206), an alarm that can be recognized by the administrator and the user is issued to notify that it has been taken out.

  If the elapsed time has not passed, the elapsed time is continuously counted in step (1203) and step (1204). In steps (1203) and (1204), when recording is detected, the elapsed time counting is ended.

  FIG. 13 shows an example in which a radio shielding material is attached to the management target article (201) and the carry-out certificate article (203). By placing the managed article (201) and the carry-out certificate article (203), for example, a wireless shielding material (1301) (1302) such as a metal material covers the IC tag c (206) storing the location identification ID. In this way, it is mounted on the bottom surface of the article to be managed (201) and the carry-out certificate article (203). As a result, the IC tag c (206) storing the location identification ID cannot be received wirelessly from the ID data reader 1 (207) by placing the management target article (201) and the take-out certificate article (203). It is a structure.

This is an example of a subsystem (1400) that urgently checks the lending status when the main system (100) stops for some reason. Separately from the ID data reading device 1 (207), the ID data reading device 2 (1401) not connected to the state database (104) reads the ID data of the article currently stored in the storage location.

  The take-out discriminating unit (1402) refers to the take-out certificate item ID definition table 2 (102) in which the take-out / department information is registered in advance, and the management target placed in the item storage location (202) The ID data A of the article (201) and the ID data B that identifies the carry-out proof article (203) are read and the matched carry-out proof article ID data is discriminated, thereby taking out any managed article. The contact information can be determined from the person and department information. Here, the subsystem (1400) is a system that functions as a stand-alone by holding only the carry-out article ID definition table 2 (102), and operates independently from the main system (100) in an emergency. Is possible.

  As described above, according to the article management system of the present embodiment, in addition to the identification ID data A of the management target article (201), the identification ID data B of the carry-out certificate article (203) to be stored instead at the time of take-out The ID data reading device 1 (207) wirelessly reads the three types of ID data of the identification ID data C, which can be stored in the article storage location (205) at all times. Each time an article is taken out or placed, the storage state is automatically recorded and updated, and an alarm is issued by detecting that ID data A and ID data B cannot be read for a predetermined elapsed time. If there is an unknown time even in a short time, the administrator can quickly grasp.

  Further, it is possible to identify the place where the IC tag c (206) storing the location identification ID data C is directly attached as data without worrying about the shelf number or the order of arrangement, and the managed article (201). Even if it is returned to a location different from when it was taken out, the correspondence with the new location identification ID data C is automatically recorded, so it can be used without worrying about the storage location, improving the convenience for the user Can be made.

  In addition, the identification ID data B of the take-out certificate article (203) placed as an alternative to the management target article (201) defines only the correspondence with the information related to the take-out person, and for which management target article (201) However, it is possible to place the take-out proof article (203) instead, and take out the ID by reading the ID of the carry-out proof article (203) stored in the storage location in the event of a system failure or the like. It becomes possible to obtain information related to the person in charge, and it becomes possible to know the contact in case of emergency.
