[0012] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Fig. 1 is a functional block diagram showing functions of a detection system according to an embodiment of the present disclosure. Note that the container in this embodiment will be described as a bag container. The detection system 100 shown in Fig. 1 includes two wireless tags 200 and an opening detection device 400. In this embodiment, one of the two wireless tags 200 is referred to as a detection wireless tag 200A, and the other wireless tag 200 is referred to as a confirmation wireless tag 200B.
[0013] (Radio tag 200) The wireless tag 200 is a sticker-type wireless tag that can be attached to the bag container 1. The wireless tag 200 comprises a label body (not shown) and a wireless tag circuit element 300 (see FIG. 2A). The label body is a long label with the longitudinal direction as the long side. The label body has a central portion located at the center in the longitudinal direction, and both end portions located on either side of the central portion in the longitudinal direction. An adhesive portion (e.g., an adhesive sticker) is disposed on the back side of the label body. In other words, the label body (wireless tag 200) is attached to the bag container 1 by the adhesive portion.
[0014] (RFID circuit element 300) The RFID circuit element 300 has a loop antenna section 310, an IC circuit section 320, a capacity hat section 330, and a meander line antenna section 340. The loop antenna section 310, the capacity hat section 330, and the meander line antenna section 340 of the detection RFID tag 200A may be referred to as the loop antenna section 310A, the capacity hat section 330A, and the meander line antenna section 340A, respectively. The loop antenna section 310, the capacity hat section 330, and the meander line antenna section 340 of the confirmation RFID tag 200B may be referred to as the loop antenna section 310B, the capacity hat section 330B, and the meander line antenna section 340B, respectively.
[0015] (Opening detection device 400) The opening detection device 400 has an antenna 410, a reader 420 (corresponding to the "reading unit" in this disclosure), a detection unit 430, a storage unit 440, and a notification unit 450. The opening detection device 400 also has a control unit (not shown) that comprehensively controls the entire device. The opening detection device 400 corresponds to the "detection device" in this disclosure.
[0016] The loop antenna unit 310 is disposed in the center of the label body. The loop antenna unit 310 transmits and receives signals to and from the antenna 410 in a non-contact manner. This allows the reader 420 to read predetermined information from the memory unit of the IC circuit unit 320 via the loop antenna unit 310.
[0017] The IC circuit section 320 is disposed in the center of the label body. The IC circuit section 320 has a rectifier section (not shown) that rectifies the carrier wave received by the loop antenna section 310, a memory section (not shown) that stores a predetermined information signal received by the loop antenna section 310, and a control section (not shown) that controls the operation of the RFID circuit element 300.
[0018] The capacity hat portion 330 is disposed on each of both ends of the label body. The capacity hat portion 330 accumulates the energy of the carrier wave rectified by the rectifier portion so as to use it as a driving power source for the RFID circuit element 300.
[0019] The meander line antenna portion 340 is disposed at each of both ends of the label body. The meander line antenna portion 340 has one end and the other end, with the loop antenna portion 310 connected to one end and the capacity hat portion 330 connected to the other end.
[0020] FIG. 2A is a diagram showing an example of a wireless tag attached to a bag container in the embodiment of the present disclosure. A tear line 2 for opening is displayed on the bag container 1 shown in FIG. 2A. Moreover, the detection wireless tag 200A shown in FIG. 2A is arranged on the tear line 2. Moreover, the longitudinal direction of the label body and the extending direction of the tear line 2 are mutually perpendicular directions. Specifically, the detection wireless tag 200A is attached to the bag container 1 such that the loop antenna unit 310A arranged in the center of the label body is arranged on the tear line 2. Therefore, when the bag container 1 is cut along the tear line 2 by scissors 3 when opening the bag container 1, the loop antenna unit 310A is cut at the same time. This causes the detection wireless tag 200A to malfunction, making it impossible for the reader 420 to read the detection tag ID (identification information) of the detection wireless tag 200A, and making it impossible for the detection unit 430 to detect the detection tag ID of the detection wireless tag 200A.
[0021] The confirmation wireless tag 200B shown in FIG. 2A is attached to the bag container 1 so as to be located in an area where the cut line 2 of the label main body is not displayed. In other words, the confirmation wireless tag 200B is not located on the cut line 2. The loop antenna section 310B is also not located on the cut line 2. The longitudinal direction of the label main body and the direction in which the cut line 2 is extended are perpendicular to each other. Therefore, when the bag container 1 is cut along the cut line 2 by scissors 3 when the bag container 1 is opened, the loop antenna section 310B is not cut. This allows the reader 420 to read the confirmation tag ID (identification information) of the confirmation wireless tag 200B without causing a malfunction of the confirmation wireless tag 200B. Also, the detection section 430 can detect the confirmation tag ID of the confirmation wireless tag 200B.
[0022] FIG. 2B is a diagram showing another example of a wireless tag attached to a bag container according to an embodiment of the present disclosure. A tear line 2 for opening is displayed on the bag container 1 shown in FIG. 2B. The detection wireless tag 200A shown in FIG. 2B is attached to the bag container 1 so that the loop antenna part 310A arranged in the center of the label body, and the capacity hat part 330A and the meander line antenna part 340A arranged at both ends of the label body are arranged on the tear line 2. The longitudinal direction of the label body and the extending direction of the tear line 2 are parallel to each other. Therefore, when the bag container 1 is cut along the tear line 2 by scissors 3 when opening the bag container 1, the loop antenna part 310A, the capacity hat part 330A and the meander line antenna part 340A are simultaneously cut. This causes the detection wireless tag 200A to malfunction, making it impossible for the reader 420 to read the detection tag ID of the detection wireless tag 200A, and making it impossible for the detection unit 430 to detect the detection tag ID of the detection wireless tag 200A.
[0023] The confirmation wireless tag 200B shown in FIG. 2B is attached to the bag container 1 so as to be located in an area where the cut line 2 of the label main body is not displayed. In other words, the confirmation wireless tag 200B is not located on the cut line 2. The loop antenna section 310B is also not located on the cut line 2. In addition, the longitudinal direction of the label main body and the direction in which the cut line 2 is extended are parallel to each other. Therefore, when the bag container 1 is cut along the cut line 2 by scissors 3 when opening the bag container 1, the loop antenna section 310B, the capacity hat section 330B and the meander line antenna section 340B are not cut. This allows the reader 420 to read the confirmation tag ID of the confirmation wireless tag 200B without causing the confirmation wireless tag 200B to malfunction. In addition, the detection section 430 can detect the confirmation tag ID of the confirmation wireless tag 200B.
[0024] That is, when the bag container 1 is unopened, the reader 420 is able to read both the detection tag ID and the confirmation tag ID. Also, the detection unit 430 is able to detect both the detection tag ID and the confirmation tag ID. Therefore, when the detection unit 430 can detect both the detection tag ID and the confirmation tag ID, it is possible to confirm that the bag container 1 is unopened.
[0025] When the bag container 1 is opened, the reader 420 is unable to read the detection tag ID, but is able to read the confirmation tag ID. Furthermore, the detection unit 430 is unable to detect the detection tag ID, but is able to detect the confirmation tag ID. Therefore, when the detection unit 430 is unable to detect the detection tag ID, but is able to detect the confirmation tag ID, it becomes possible to confirm that the bag container 1 has been opened.
[0026] The control unit (not shown) of the opening detection device 400 determines whether the detection tag ID and the confirmation ID are paired information linked together. If the detection tag ID and the confirmation ID are paired information linked together and the opening of the bag container 1 is confirmed, the confirmation tag ID, the opening flag, and the opening date are stored in the memory unit 440.
[0027] The notification unit 450 notifies the user of the confirmation tag ID and the opening date read from the storage unit 440. Specifically, the notification unit 450 is a display unit that displays the tag ID and the opening date as character data. The notification unit 450 may notify the user of the confirmation tag ID and the opening date on the opening date, or may notify the user of the confirmation tag ID and the opening date after the opening date, for example, by a user's input operation.
[0028] The detection system 100 in the above embodiment includes a detection wireless tag 200A having a loop antenna portion 310A and arranged on a cut line 2 for opening displayed on a bag container 1, a confirmation wireless tag 200B having a loop antenna portion 310B and arranged in an area of the bag container 1 where the cut line 2 is not displayed, and an opening detection device 400. The opening detection device 400 includes an antenna 410 which transmits and receives signals between the loop antenna portions 310A and 310B by wireless communication, and a detection wireless tag 200 via the antenna 410. The device is equipped with a reader 420 capable of reading both the detection tag ID of A and the confirmation tag ID of the confirmation wireless tag 200B, a detection unit 430 for detecting that the bag container 1 has been opened when the detection tag ID cannot be read but the confirmation tag ID can be read, a memory unit 440 for storing the opening date when the bag container 1 has been opened when it is detected that the bag container 1 has been opened, and a notification unit 450 for notifying the opening date when the pair information is linked to a detection tag ID that cannot be read and a confirmation tag ID that can be read.
[0029] With the above configuration, when the bag container 1 is opened, the opening date is automatically notified, eliminating the need for an operator to make a note of the opening date, thereby improving workability after opening the bag container 1. Furthermore, when the detection tag ID and the confirmation tag ID are paired information linked together, the opening date is notified, making it possible to confirm that the bag container with the detection tag ID attached has been opened.
[0030] Although the container in the above embodiment has been described as the bag container 1, the present disclosure is not limited to the bag container 1. For example, the container may be a box container.
[0031] (Variation 1) Next, a first modified example of the present embodiment will be described with reference to Fig. 3. Fig. 3 is a diagram showing the relationship between the detection system and the terminal device in the first modified example of the present embodiment. In the description of the first modified example, configurations different from the above embodiment will be mainly described, and the same configurations will be denoted by the same reference numerals and descriptions thereof will be omitted.
[0032] The detection system 100 in the first modification includes a terminal device 5. The terminal device 5 is, for example, a smartphone or a tablet terminal. The terminal device 5 has a communication unit (not shown) that performs data communication with the opening detection device 400. As a result, the terminal device 5 receives the item name and the opening date, stores them in a memory (not shown), and displays the item name and opening date read from the memory on a display. The item name and opening date displayed on the display are shown in FIG. 3.
[0033] In the detection system 100 in the first modification, the product name and the opening date are stored in the memory and are also displayed on the display. This eliminates the need for the worker to take a note of the opening date, which improves the workability after the bag container is opened.
[0034] (Variation 2) Next, a second modification of the present embodiment will be described with reference to Fig. 4. Fig. 4 is a functional block diagram showing the functions of a detection system in a second modification of the present embodiment. In the description of the second modification, configurations different from those in the above embodiment will be mainly described, and the same configurations will be denoted by the same reference numerals and descriptions thereof will be omitted.
[0035] The detection system 100 in the second modification includes a server 500. The opening detection device 400 also includes a communication unit 460 that performs data communication with the server 500.
[0036] The communication unit 460 transmits the detection tag ID, the confirmation tag ID, and the opening date to the server 500. When the detection tag ID and the confirmation tag ID are linked, the communication unit 460 receives pair information, item information (described later), and other additional information (described later) from the server 500. This enables the notification unit 450 to notify the item information and other additional information in addition to the opening date.
[0037] Server 500 has a memory unit 510, a collation unit 520, and a notification unit 530. Memory unit 510 stores a first list and a second list. The first list is a list in which detection tag IDs are linked to item information. The item information includes the product name, an external image of the item, the expiration date after opening, and other additional information. The second list is a list in which detection tag IDs are linked to confirmation tag IDs.
[0038] The matching unit 520 refers to the first list based on the detection tag ID transmitted from the communication unit 460, and matches the detection tag ID with the object information. The matching unit 520 also refers to the second list based on the detection tag ID and the confirmation tag ID transmitted from the communication unit 460, and matches the detection tag ID with the confirmation tag ID. When the detection tag ID and the confirmation tag ID are linked, the server 500 transmits the pair information and the object information to the communication unit.
[0039] The notification unit 450 of the opening detection device 400 notifies the opening date and other additional information. Specifically, the notification unit 450 displays the opening date, item information (including the expiration date after opening) and other additional information as character data.
[0040] When the detection tag ID and the confirmation tag ID are linked, the notification unit 530 of the server 500 notifies the opening date, the item information, and other additional information. Specifically, the notification unit 530 displays the opening date, the item information (including the expiration date after opening), and other additional information as character data.
[0041] In the detection system 100 in the second modification, the opening date, item information (including the expiration date after opening) and other additional information are displayed on the notification unit 450 of the opening detection device 400 and the notification unit 530 of the server 500. This eliminates the need to make a note of the opening date and makes it easy to manage the expiration date and the like.
[0042] In addition, the above-mentioned embodiments are merely examples of the embodiment of the present disclosure, and the technical scope of the present disclosure should not be interpreted as being limited by them. In other words, the present disclosure can be embodied in various forms without departing from the gist or main features thereof. [Industrial Applicability]
