Description

[Technical Field]

[0001] An embodiment of the present invention relates to an article management device and a program. [Background technology]

[0002] Conventionally, devices have been proposed that manage the status of items by attaching wireless tags such as RFID (Radio Frequency Identifier) ​​tags to items and reading the information stored in the wireless tags. For example, a technology has been proposed that stores the expiration date of an item in an RFID tag and notifies users that an item is close to expiring based on the read expiration date.

[0003] However, while conventional technologies can determine whether an item has expired, it is difficult to determine, for example, how much time has passed since the item was left in a certain environment. Therefore, there is room for further improvement in the management of item status. Summary of the Invention [Problem to be solved by the invention]

[0007] An embodiment of an article management device will be described in detail below with reference to the accompanying drawings. In this embodiment, an example will be described in which the article management device is applied to a device that manages the state of vaccines contained in containers such as vials, but the present invention is not limited to this form. Note that, hereinafter, a container containing a vaccine will also be simply referred to as a vaccine.

[0008] (Hardware configuration of the item management device) As shown in FIG. 1, the item management device 100 has a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, an auxiliary storage device 14, an input device 15, a display device 16, a reading device 17, and an external I / F (Interface) 18.

[0009] The CPU 11 is a computing device that reads out programs and data stored in the ROM 12, auxiliary storage device 14, etc. onto the RAM 13 and executes processing to realize each function of the item management device 100. The RAM 13 is a volatile memory used as a work area, etc. for the CPU 11. The ROM 12 is a non-volatile memory.

[0010] The auxiliary storage device 14 is a recording device such as a hard disk drive (HDD) or a solid state drive (SSD), and stores, for example, an operating system (OS), application programs, various data, and the like.

[0011] The input device 15 is a device that allows a user of the article management device 100 to perform various operations. The input device 15 is configured, for example, as a touch panel or hardware keys. The display device 16 is a display device that displays various information read by the reading device 17. The display device 16 is configured, for example, as a liquid crystal display, and the input device 15 and the display device 16 may be configured as one unit, for example, in the form of a touch panel.

[0012] The reading device 17 is a device that reads identification information capable of identifying each of the articles, i.e., each of the wireless tags, from the wireless tags attached to each of the articles to be managed, i.e., each of the vaccines. For example, the reading device 17 is a wireless tag reader / writer.

[0013] A wireless tag reader / writer has an antenna and detects wireless tags attached to items within the antenna's communication range. That is, the wireless tag reader / writer transmits radio waves from the antenna to surrounding wireless tags. When the wireless tags receive the radio waves from the antenna, they transmit a response signal to the wireless tag reader / writer.

[0014] The wireless tag reader / writer receives a response signal from the wireless tag and reads the tag information recorded in the memory of the wireless tag. The tag information includes at least the above-mentioned identification information. The tag information may also include a time indicator from the viewpoint of quality control, such as the expiration date or best-before date of the product (for example, a threshold value for timing the threshold elapsed time, which will be described later). An anti-collision method is used to control communication between the wireless tag reader / writer and the wireless tag. This allows the wireless tag reader / writer to read the tag information of each wireless tag simultaneously when multiple wireless tags are present within the communication range of the antenna.

[0015] A wireless tag has an internal non-volatile memory that contains an ID area for recording a unique ID (Identifier) ​​assigned by the manufacturer during the manufacturing process of the wireless tag, and a user area in which the user can write any data.

[0016] In this embodiment, the above-mentioned identification information is written to the user area of ​​the wireless tag. The wireless tag reader / writer reads the ID and the identification information from the wireless tag as tag information. For example, the wireless tag is an RFID.

[0017] The wireless tag reader / writer performs a duplication check based on the ID included in the read tag information, thereby controlling the reading of tag information (identification information) including the same ID in duplicate. The item management device 100 can then perform a record process of the item based on the identification information read by the wireless tag reader / writer.

[0018] The external I / F 18 is a communication interface for connecting the article management device 100 to a network.

[0019] Next, the functional configuration of an item management device 100 according to an embodiment will be described. Fig. 2 is a block diagram showing an example of the functional configuration of the item management device 100. The item management device 100 functions as an acquisition unit 21, a recording unit 22, a first timing processing unit 23, a determination unit 24, a second timing processing unit 25, a management unit 26, an input unit 27, and an alignment unit 28, as a result of the CPU 11 operating in accordance with a control program recorded in the ROM 12 or RAM 13. Note that each of the above functional configurations may be realized by hardware, as long as the item management device 100 has the above functions.

[0020] The acquisition unit 21 is an example of an acquisition unit. The acquisition unit 21 repeatedly acquires identification information that can identify an item from a wireless tag attached to the item by cooperating with the reading device 17. For example, when the reading device 17 detects an item, the acquisition unit 21 operates the reading device 17 to start reading the wireless tag and acquires the identification information of the item read by the reading device 17.

[0021] The acquisition unit 21 repeatedly acquires the identification information recorded on the wireless tag of the item from the reading device 17 at predetermined time intervals. By repeatedly acquiring the information at predetermined time intervals, the acquisition unit 21 can appropriately grasp the quality state of the item. Note that the predetermined time interval may be determined in advance according to the characteristics of the quality state of the item, or may be determined by the user, but is not limited to this.

[0022] The recording unit 22 is an example of a recording unit. Every time the acquiring unit 21 acquires identification information, the recording unit 22 associates the identification information with the acquisition date and time and records the identification information. Here, the acquisition date and time refers to the date and time acquired by the acquiring unit 21. The acquisition date and time can be acquired, for example, based on date and time information measured by a timing device such as an RTC (Real-time clock) included in the item management device 100.

[0023] The first timing processing unit 23 is an example of a timing processing unit. The first timing processing unit 23 measures the time at which the identification information is continuously acquired for each piece of identification information acquired by the acquisition unit 21. Specifically, the first timing processing unit 23 measures the elapsed reading time based on the acquisition date and time recorded by the recording unit 22.

[0024] Here, a method in which the article management device 100 acquires information on a wireless tag attached to an article will be described with reference to Fig. 3. Fig. 3 is a schematic configuration diagram showing an example of how the article management device 100 according to an embodiment reads an article. Fig. 3 shows vaccines (31, 32, 33, 34, 35), a container 36, and a mounting table 37, which are examples of articles.

[0025] Each of the vaccines (31, 32, 33, 34, 35) is provided with a wireless tag (311, 312, 313, 314, 315). The container 36 stores the vaccines (34, 35) and manages the vaccines (34, 35) in an appropriate quality state. For example, the container 36 is a freezer. The vaccines (31, 32, 33) removed from the container 36 are placed on the mounting table 37. The mounting table 37 also includes an antenna for the reading device 17 inside or below the mounting table 37. The vaccines placed on the mounting table 37 are kept at room temperature.

[0026] 3, the acquisition unit 21 cooperates with the wireless tag reader / writer to repeatedly acquire identifiable identification information from the wireless tags (311, 312, 313) attached to the vaccines (31, 32, 33) placed on the mounting table 37. For example, the acquisition unit 21 operates the wireless tag reader / writer to repeatedly read the wireless tags at predetermined time intervals (for example, one minute intervals) and acquires the tag information (identification information) read each time.

[0027] 4 is a diagram showing an example of a table in which the article management device 100 according to the embodiment records articles. The table is stored in the RAM 13 or the auxiliary storage device 14 of the article management device 100.

[0028] As shown in Fig. 4, the table stores, for each ID, which is identification information capable of identifying each item, the time at which the ID was acquired. Here, the time stored (recorded) in the table corresponds to the acquisition date and time at which the acquisition unit 21 acquired tag information. When the acquisition unit 21 acquires tag information, the recording unit 22 records the acquisition date and time (time) in the table in association with the identification information (ID) included in the tag information. Note that the example in Fig. 4 shows an example in which the acquisition unit 21 acquires tag information at one-minute intervals.

[0029] The first timing processing unit 23 counts the time during which each piece of identification information has been continuously acquired, based on the acquisition date and time recorded in the table.

[0030] 3 and 4, the operation of first timing processing unit 23 will be described. For example, assume that vaccines 31 and 32 are removed from container 36 at 9:30 and placed on table 37 until 17:30. In this case, acquisition unit 21 continuously acquires tag information from the wireless tags attached to vaccines 31 and 32 between 9:30 and 17:30, and the recording results by recording unit 22 are as shown in FIG. 4. Here, ID311 means the ID of the wireless tag attached to vaccine 31, and ID312 means the ID of the wireless tag attached to vaccine 32.

[0031] In the state of the table shown in FIG. 4, the first timing processing unit 23 measures eight hours as the elapsed reading time for ID311 based on the length of time (9:30 to 17:30) of the acquisition time recorded in association with the ID. The first timing processing unit 23 measures three hours as the elapsed reading time for ID312 based on the length of time (9:30 to 12:30) of the acquisition time recorded in association with the ID. The first timing processing unit 23 also records the measured elapsed reading time in a table. Note that the recording method may be other than storing in a table, and is not limited to this.

[0032] The elapsed reading time is updated each time the first timing processing unit 23 measures time, that is, each time tag information is acquired by the acquisition unit 21. If an ID recorded in the table becomes unreadable due to, for example, the vaccine being moved during the process, the timing of the elapsed reading time may be stopped or continued. For example, in the former case, the elapsed reading time may be reset. In the latter case, when the period during which reading has ceased reaches a predetermined time, the timing of the elapsed reading time may be stopped, or the record of the corresponding ID may be deleted from the table.

[0033] Returning to Figure 2, the determination unit 24 is an example of a determination unit. The determination unit 24 determines whether the acquisition time acquired by the acquisition unit 21 exceeds a threshold value. Specifically, the determination unit 24 compares a preset threshold value with the elapsed reading time measured by the first timing processing unit 23, and determines whether the elapsed reading time of the vaccine placed on the mounting table 37 exceeds the threshold value.

[0034] The threshold is preferably set to the time for storage at room temperature, which is the upper limit (or lower limit) for managing the quality of the vaccine. In this embodiment, the threshold is, for example, the time it takes for the vaccine to become thawed (4 hours). Note that the threshold can be set arbitrarily and is not limited to this.

[0035] The second timing processing unit 25 is an example of a timing processing unit. When the elapsed reading time measured by the first timing processing unit 23 exceeds a threshold, the second timing processing unit 25 measures a threshold elapsed time exceeding the threshold. Specifically, when the determination unit 24 determines that the threshold has been exceeded, the second timing processing unit 25 measures the time exceeding the threshold.

[0036] Here, the operation of the second timing processing unit 25 will be described with reference to Fig. 4. In the case of the table shown in Fig. 4, the second timing processing unit 25 compares the elapsed reading time recorded in association with ID 311 with a threshold value (for example, 4 hours). If the elapsed reading time exceeds the threshold value, timing of the threshold elapsed time starts from the time (13:30) at which the threshold value was exceeded. Then, for example, when it reaches 17:30, the second timing processing unit 25 counts 4 hours as the threshold elapsed time based on the length of time from 13:30 to 17:30.

[0037] Similarly, for ID313, the second timing processing unit 25 compares the recorded elapsed reading time associated with the ID with a threshold value (4 hours), and when it detects that the threshold value has been exceeded at 16:30, it starts timing the threshold elapsed time from 16:30. Then, for example, when it reaches 17:30, the second timing processing unit 25 counts one hour as the threshold elapsed time based on the length of time from 16:30 to 17:30. The threshold value related to the elapsed reading time may be stored in advance in the auxiliary storage device 14 or the like, or may be specified by the user via the input unit 27 or the like, which will be described later.

[0038] As described above, since the threshold is four hours, the determination unit 24 determines that the state of vaccine 31 stored at room temperature for ID 311 has exceeded the threshold at 1:30 PM. The determination unit 24 also determines that the state of vaccine 33 stored at room temperature for ID 313 has exceeded the threshold at 4:30 PM. The second timing processing unit 25 starts measuring the time that has exceeded the threshold, depending on the determination result of the determination unit 24.

[0039] The threshold elapsed time measured by the second timing processing unit 25 is recorded in a table. Note that the recording method may be other than storing in a table, and is not limited to this. The threshold elapsed time is updated every time the second timing processing unit 25 measures time, that is, every time the acquisition unit 21 acquires tag information.

[0040] In this embodiment, the first timing processing unit 23 and the second timing processing unit 25 are configured separately, but a single timing processing unit may also be configured to perform the functions of both the first timing processing unit 23 and the second timing processing unit 25.

[0041] Returning to FIG. 2, the management unit 26 is an example of a management unit. The management unit 26 manages the elapsed reading time measured by the first timing processing unit 23 in association with the identification information. The management unit 26 also manages the vaccine based on the elapsed reading time measured by the first timing processing unit 23 and the threshold elapsed time measured by the second timing processing unit. Note that the management method may be other than the table, and is not limited to this. The management unit 26 also displays a table on the display device 16 in response to a user's operation via the input device 15.

[0042] Furthermore, the management unit 26 displays the elapsed reading time measured by the first timing processing unit 23 and the threshold elapsed time measured by the second timing processing unit 25 on the display device 16 for each piece of identification information. The management unit 26 also associates the identification information with the threshold elapsed time and displays them on the display device 16. For example, taking a two-axis graph as an example of the change over time, the management unit 26 displays on the display device 16 for each piece of identification information, the horizontal axis representing the time acquired by the acquisition unit 21 and the vertical axis representing the threshold elapsed time measured by the second timing processing unit 25.

[0043] Furthermore, when the second timing processing unit 25 starts timing processing, the management unit 26 notifies the display device 16. For example, when the threshold is exceeded, the management unit 26 displays a warning message on the display device 16 saying, "The threshold elapsed time has been exceeded, so please check the vaccine," and also highlights the ID of the corresponding vaccine on the display device 16. Note that the method of notification may be other than displaying on the display device 16, and is not limited to this. Furthermore, when the user confirms the content of the notification, the management unit 26 does not need to notify the user again, and the number of times to notify may be set by providing a separate threshold.

[0044] The input unit 27 is an example of an input unit. The input unit 27 cooperates with the input device 15 to operate the items of identification information, acquisition date and time, elapsed reading time, and threshold elapsed time selected by the user in the table. The user uses the input unit 27 when he / she wants to change the items to be displayed on the display device 16 or when he / she wants to change the threshold set by the article management device 100. For example, the user inputs information into the input unit 27 when he / she wants to change the items to be displayed on the display device 16 by the management unit 26. Furthermore, when the user wants to change the threshold, the user inputs the changed threshold into the input unit 27.

[0045] The alignment unit 28 is an example of an alignment unit. In response to a user's operation, the alignment unit 28 rearranges the display order of information (acquisition date and time, elapsed read time, and threshold elapsed time) related to each piece of identification information displayed on the display device 16 by the management unit 26. For example, the alignment unit 28 rearranges the display order so that information with a longer elapsed read time is displayed at the top. Also, for example, the alignment unit 28 rearranges the display order so that information with a longer threshold elapsed time is displayed at the top. This makes it easier to recognize identification information with a longer elapsed read time or threshold elapsed time, thereby improving the convenience of item management.

[0046] It is possible to arbitrarily set which of the reading elapsed time and the threshold elapsed time is to be displayed with priority, but from the viewpoint of quality control, it is preferable to display the longer threshold elapsed time at the top.

[0047] The sorting unit 28 may also rearrange the information displayed on the display device 16 in response to a user operation via the input unit 27. For example, if the user wants to rearrange the information by the time the threshold was exceeded, the sorting unit 28 rearranges the information in descending order of the time the threshold was exceeded. Note that the sorting method can be set arbitrarily and is not limited to this. The functions of the sorting unit 28 may also be implemented by the management unit 26.

[0048] Next, an example of the operation of the article management device 100 having the above-described configuration will be described with reference to Fig. 5. Fig. 5 is a flowchart showing an example of processing executed by the article management device 100 of the embodiment.

[0049] First, the acquisition unit 21 determines whether a predetermined time (for example, one minute) has elapsed, which is the time interval for acquiring tag information. If the predetermined time has elapsed (step S1: Yes), the process proceeds to step S2. If the predetermined time has not elapsed (step S1: No), the process returns to step S1, and the process waits until the predetermined time has elapsed.

[0050] Next, the acquisition unit 21 acquires tag information including identification information (ID) from the wireless tag attached to each of the articles (step S2). After the acquisition process is completed, the process proceeds to step S3.

[0051] The recording unit 22 determines whether the acquired ID is a new ID that is not recorded in the table. If the acquired ID is new (step S3: Yes), the recording unit 22 records the new ID in the table (step S4) and proceeds to step S5. If the acquired ID is registered in the table (step S3: No), the process proceeds to step S5.

[0052] Next, the first timing processing unit 23 times the time of the ID acquired by the acquisition unit 21 (step S5). When the timing process is performed, the first timing processing unit 23 records the time. When the recording process is performed, the management unit 26 manages the time in association with the identification information.

[0053] Next, the determination unit 24 determines whether the elapsed reading time measured by the first timing processing unit 23 exceeds a threshold value (step S6). If the measured elapsed reading time exceeds the threshold value (step S6: Yes), the process proceeds to step S7. If the measured elapsed reading time does not exceed the threshold value (step S6: No), the process returns to step S1.

[0054] When the determination unit 24 determines that the threshold has been exceeded, the second timing processing unit 25 times the threshold elapsed time beyond the threshold (step S7). When the timing process is performed, the second timing processing unit 25 records the time thus measured. When the recording process is performed, the management unit 26 associates the reading elapsed time measured by the first timing processing unit 23 with the threshold elapsed time measured by the second timing processing unit 25 for each piece of identification information, thereby managing the vaccine.

[0055] Next, management unit 26 notifies that the vaccine has exceeded the threshold (step S8). Management unit 26 notifies display device 16 of the identification information, the display order of which has been rearranged by alignment unit 28 so that the identification information with the longer elapsed time beyond the threshold is displayed at the top. After the notification process is performed, processing returns to step S1, and the process waits until a predetermined time has elapsed.

[0056] As described above, in the item management device according to this embodiment, the acquisition unit repeatedly acquires item identification information from the wireless tag attached to the item. The first timing processing unit measures the time at which the identification information is acquired. The management unit manages the measured elapsed reading time in association with the identification information.

[0057] This allows the time acquired by the item to be measured and managed in association with the identification information. The item management device can grasp the status of the item from the managed information, thereby efficiently managing the status of the item.

[0058] The above-described embodiment can be modified as needed by changing a portion of the configuration or function of the above-described device. Therefore, several modifications of the above-described embodiment will be described below as other embodiments. The following mainly focuses on differences from the above-described embodiment, and detailed descriptions of commonalities with the content already described will be omitted. The modifications described below may be implemented individually or in appropriate combination.

[0059] (Variation 1) In the above-described embodiment, the managed items are vaccines, but this is not limiting. For example, the managed items may be fresh food or the like. Furthermore, the container may be a refrigerator or tray for storing fresh food or the like. Furthermore, the location where the item management device is applied is not limited to medical settings, and may be a store selling fresh food or the like, a store's back yard, or the like.

[0060] (Variation 2) In the above-described embodiment, a wireless tag is attached to the vaccine, which is an item to be managed. However, a wireless tag may also be attached to a container, for example. In this case, the placement table 37 of the item management device is installed where the container is placed and measures the elapsed time since the container was placed in that location. For example, in stores such as convenience stores, trays containing refrigerated products may be placed in rooms that are not temperature-controlled. In such cases, by installing the placement table 37 where the tray is placed, the elapsed time since it was placed in that location can be managed.

[0061] (Variation 3) For example, the identification information stored in the wireless tag may be written on the product itself, such as a vaccine, making it easy to identify products that have exceeded the threshold.

[0062] (Variation 4) In the above embodiment, the notification content is sent to the display device of the item management device, but it may also be sent to, for example, an information processing terminal owned by the user, which allows the user to manage the items even when the user is away from the place where the items are managed.

[0063] (Variation 5) In the above-described embodiment, the reading device is provided on the table, but the reading device may be provided in a location other than the table, and is not limited to this. The reading device may be placed in a location where it can read the wireless tag, for example, on a wall or ceiling in a room where the item is stored.

[0064] (Variation 6) In the above embodiment, the first timing processor stores the reading time in a table, but for example, the recording unit may record the reading time in a table. Also, while the second timing processor stores the reading time in a table, for example, the recording unit may record the reading time in a table.

[0065] (Variation 7) In the above-described embodiment, the second timing processing unit is configured to start timing the threshold elapsed time based on a threshold set in advance in the auxiliary storage device 14 or the like, but the referenced threshold is not limited to this configuration. For example, if a threshold is included in tag information, the second timing processing unit may measure the threshold elapsed time for the identification information included in the tag information based on the threshold included in the tag information acquired by the acquisition unit 21. This allows the second timing processing unit to switch the threshold (time) at which to start timing the threshold elapsed time for each piece of identification information, and therefore, for example, it is possible to set the threshold elapsed time individually for each type of vaccine.

[0066] The computer program executed by the item management device 100 of this embodiment is provided as a file in an installable or executable format recorded on a computer-readable recording medium such as a CD-ROM, a flexible disk (FD), a CD-R, or a DVD (Digital Versatile Disk).

[0067] The computer program executed by the item management device 100 of this embodiment may be stored on a computer connected to a network such as the Internet and provided by being downloaded via the network. The computer program executed by the item management device 100 of this embodiment may be provided or distributed via a network such as the Internet.

[0068] Furthermore, the computer program executed by the article management device 100 of this embodiment may be provided by being pre-installed in a ROM or the like.

[0069] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included within the scope and spirit of the invention, and are also included in the scope of the invention and its equivalents as defined in the claims.
