  Next, a state where the user is moving indoors will be described with reference to FIGS. FIG. 7 is a schematic diagram showing that the user is moving indoors in the first embodiment. FIG. 8 is an explanatory diagram of the reading status and status when the user moves indoors in the first embodiment. As shown in FIG. 7, when the user 80 entering the room through the door 71 moves in the room, the user 80 is interposed between the IC tag 20 attached to the inner wall 72 of the toilet 70 and the IC tag reader 30. The tag ID (B) cannot be read. In this case, as shown in FIG. 8, the IC tag ID (B) cannot be read and the other IC tag IDs (A, C to F) can be read. (S140).

  Next, a state in which the user is using the toilet bowl will be described with reference to FIGS. FIG. 9 is a schematic view during use of the toilet by the user in the first embodiment. FIG. 10 is an explanatory diagram of reading status and status when the user is using the toilet bowl in the first embodiment. As shown in FIG. 9, when the user 80 uses the toilet 75, the user 80 is interposed between the IC tag 20 attached to the tank of the toilet 75 and the IC tag reader 30, so that the IC tag ID (E) Cannot be read. In this case, as shown in FIG. 10, the IC tag ID (E) cannot be read and the other IC tag IDs (A to D, F) can be read. (S140).

  Next, a state in which the user is using the toilet will be described with reference to FIGS. FIG. 11 is a schematic view showing that the user is using the toilet in the first embodiment. FIG. 12 is an explanatory diagram of the reading status and status in the washroom by the user in the first embodiment. As shown in FIG. 11, when the user 80 uses the washroom 74, the user 80 is interposed between the IC tag 20 attached to the washroom 74 and the IC tag reader 30, so that the IC tag ID (D) Cannot be read. In this case, as shown in FIG. 12, the IC tag ID (D) cannot be read, and other IC tag IDs (A to C, E, F) can be read. Is stored in the memory 40 (S140).

  Next, with reference to FIG. 13 to FIG. 15, a state when the user leaves the toilet will be described. FIG. 13 is a schematic diagram when the user leaves the toilet in the first embodiment. FIG. 14 is an explanatory diagram of the reading status and status when the user leaves the toilet in the first embodiment. As shown in FIG. 13, when the user 80 tries to leave the toilet 70, the user 80 is interposed between the IC tag 20 attached to the door 71 and the IC tag reader 30, so that the IC tag ID (A) Cannot be read. In this case, as shown in FIG. 14, the IC tag ID (A) cannot be read, and other IC tag IDs (BF) can be read. (S140). When the user 80 leaves the toilet 70, an unillustrated infrared sensor or the like no longer detects the presence of the user 80, so the lamp 78 is turned off.

  By the way, the reading status of the IC tag ID is the same when entering the toilet of FIGS. 5 and 6 and when leaving the toilet of FIGS. When one toilet enters the room, it is determined that there is no toilet before that, and when the other toilet leaves the room, it is determined based on the behavior of the user 80 in the toilet 70 before that.

  Referring to FIG. 15 again, until the predetermined time range elapses (S150 / NO), IC tag reader 30 repeats the operations described with reference to FIGS. When the predetermined time range elapses (S150 / YES), the IC tag reader 30 is collected from the toilet 70, and the process proceeds to determination by the determination device 50 (S150). As described in the reading status and status of FIGS. 4, 6, 8, 10, 12, and 14, the determination device 50 is based on the IC tag 20 that did not acquire the ID information. The position of the user 80 is determined (S160).

  Then, by analyzing the determination result of the determination device 50, it is used as a reference for facility construction (S150). For example, when there are many users 80 who do not use the toilet bowl 75 and use only the mirror 73 and the washroom 74, it is analyzed that there are many female customers who remake, and the addition of the washroom 74 is considered.

  As described above, in the user position measurement system 100 according to the first embodiment, the IC tag reader 30 is arranged at a position where the IDs of the plurality of IC tags 20 can be acquired. When a user intervenes between the IC tag reader 30 and any one of the IC tags 20, acquisition of ID information of the IC tag 20 is blocked. When the user 80 moves in the toilet 70, the IC tag 20 that cannot acquire the ID information changes with time. The determination device 50 determines the position of the user 80 in the toilet 70 based on the IC tag 20 for which the IC tag reader 30 could not acquire ID information. Therefore, according to the user position measurement system 100 according to the first embodiment, the action history of the user 80 in the toilet 70 can be grasped in a predetermined time range. Since the user 80 is not specified, privacy is not harmed.

  Moreover, since the IC tag reader 30 acquires ID information from the IC tag 20 every predetermined time and gives acquisition time information to the acquired ID information, it is possible to grasp the action history of the user 80 corresponding to the time. it can. For example, by grasping the usage time of the washroom 74, it is possible to grasp the average time for a woman's re-dressing, which can be used as a reference for equipment construction.

  Furthermore, since the determination apparatus 50 includes the storage unit 60 in which the position of each IC tag 20 is stored, the ID information of the IC tag 20 and the position information are linked to accurately grasp the action history of the user 80. Can do.

[Second Embodiment]
(Configuration of measured person position measurement system)
Next, with reference to FIG.16 and FIG.18, the structure of the to-be-measured person position measuring system which concerns on 2nd Embodiment is demonstrated. FIG. 16 is an overall configuration diagram of a measurement subject position measurement system according to the second embodiment. FIG. 18 is an explanatory diagram of an IC tag arrangement and reading method according to the second embodiment. The same components as those in the first embodiment will be described with the same reference numerals.

  As shown in FIG. 16, a measurement subject position measurement system 200 according to the second embodiment includes an IC tag 20, an IC tag reader 30, and a determination device 50 as main components. Hereinafter, each component will be described.

  The IC tag 20 is a sheet tag including ID information. The IC tag 20 is disposed on a seat 202 in the airplane 201. In the present embodiment, as shown in FIG. 18, the IC tag 20 is disposed in the passage side seats 1 to 10 among the plurality of seats 202 disposed in the airplane 201. The IC tag 20 may be disposed in a seat other than the aisle-side seats 1 to 10 among the plurality of seats 202 in the airplane 201 or may be disposed in all seats disposed in the airplane 201. Good. The IC tag 20 is affixed to a pamphlet in the seat. Specifically, it is attached to “Safety Bookmark”. However, the IC tag 20 is not limited to the case where the IC tag 20 is affixed to a pamphlet in the seat. The IC tag 20 may be attached to, for example, other equipment in the seat or the seat itself.

  As the IC tag 20, for example, an RF tag (RFID: Radio Frequency Identifier) in which ID information is embedded is employed. RFID can exchange identification information using short-range wireless communication such as electromagnetic fields and radio waves. The communication distance is several centimeters to several meters depending on the frequency band.

  The IC tag reader 20 is a device for reading ID information embedded in the IC tag 20 using short-range wireless communication. The IC tag reader 30 of the present embodiment is configured as a portable type, and is held by a person to be measured. In the present embodiment, for example, a CA (Cabin Attendant) working in the airplane 201 is carried.

  For example, 900 MHz is used for the frequency band of the IC tag reader 30. The 900 MHz IC tag reader 30 can communicate with the IC tag 20 within a short distance of about 1 m. The frequency band of the IC tag reader 30 is not limited to the illustrated frequency band. In the airplane 201, a plurality of CAs are active. Since it is a short-distance communication of about 1 m, it is not necessary to consider interference, but when interference occurs, it is possible to change the frequency band of each CA.

  The IC tag reader 30 includes a memory 40 for storing acquired information. The memory 40 stores ID information and RSSI (Received Signal Strength Indication) of each IC tag 20 within a predetermined time range. The IC tag reader 30 gives acquisition time information to the acquired ID information and RSSI.

  The determination device 50 is a device for determining the position of the CA in the airplane 201. The determination device 50 determines the position of the CA in the airplane 201 based on the ID information acquired by the IC tag reader 30 and the RSSI in a predetermined time range. In the present embodiment, the seat position with the strongest reception intensity of the IC tag reader 30 is determined to be the CA position. As the determination apparatus 50, for example, a computer such as a server is employed.

  The determination device 50 includes a storage unit 60 in which the position of each IC tag 20 in the airplane 201 is stored. As the storage device 60, a readable / writable storage medium such as a hard disk (HDD) or SSD is preferably used.

(Operations of the measurement subject position measurement system)
Next, with reference to FIG.16 and FIG.17, the operation | movement of the to-be-measured person position measuring system which concerns on 2nd Embodiment is demonstrated with the to-be-measured person position measuring method which concerns on 2nd Embodiment. FIG. 17 is a flowchart of a measurement subject position measuring method according to the second embodiment.

  The subject position measurement method according to the second embodiment includes a step of acquiring ID information and RSSI from a plurality of IC tags, a step of storing ID information and RSSI of each IC tag, and ID information and RSSI. And determining the position of the person to be measured in the airplane. This will be specifically described below.

  For example, 13 CAs are on board the airplane 201, and work in teams for each seat section. As shown in FIGS. 16 and 17, when all the passengers have boarded (S210), the IC tag 20 is attached to the pamphlet in the aisle seats 1 to 10 with the portable IC tag reader 30 as the CA moves. The acquisition of the ID information is started (S220).

  The IC tag reader 30 acquires the ID information and RSSI of each IC tag 20, and gives the acquired acquisition time information (S230). The IC tag reader 30 stores the ID information, RSSI, and acquisition time information in the memory 40 (S240).

  Since CA moves through the passage in the airplane 201, the ID information and RSSI acquired by the IC tag reader 30 change with the passage of time. The steps from S220 to S240 are continued until a predetermined time range elapses (S250 / NO). Here, the predetermined time range may be from when the passenger boarding the airplane 201 is completed to landing at the destination and when the passenger gets off the airplane 201, or may be divided by a specific shift time. Absent.

  When the predetermined time range elapses (S250 / YES), the determination device 50 determines the position of the CA in the airplane 201 based on the ID information and RSSI stored in the memory 40. Since the position of the CA is recorded together with the acquisition time information, it is used as a reference for the CA work shift plan, adjustment of the number of personnel, etc. based on the determination of the determination device 50 (S270).

(Measurement experiment of measured person position measurement system)
Next, in order to determine the effectiveness of position measurement of the measurement subject position measurement system 200 according to the second embodiment, the following measurement experiment was performed. First, as a basic measurement experiment, an experiment was performed to determine whether or not sensing is possible when the CA is standing in the passage between the seats 210. FIG. 18 is an explanatory diagram of an IC tag arrangement and reading method according to the second embodiment. As shown in FIG. 18, CA stands in the vicinity of seats 5, 6, 7, and 8. Since the IC tag ID arranged in the seats 3 and 4 is away from the CA, it exists outside the range of the reception intensity of the IC tag reader 30. The IC tag ID disposed on the seat 5 is blocked by the CA itself and cannot be read by the IC tag reader 30. On the other hand, the IC tag IDs arranged on the seats 6, 7, and 8 could be read by the IC tag reader 30.

  FIG. 19 is an explanatory diagram of IC tag reading determination according to the second embodiment. As shown in FIG. 19, the determination device 50 makes a determination based on the manufacturing code (EPC: Electronic Product Code) and RSSI of the IC tag 20 arranged in the seats 6, 7, and 8 received by the IC tag reader 30. In FIG. 19, the RSSI of the seat 6 is −65, the RSSI of the seat 7 is −81, and the RSSI of the seat 8 is −75. Therefore, it was determined that the position of the seat 6 with the strongest RSSI is the current CA position.

  Next, based on the knowledge of the basic measurement experiment described above, a measurement experiment was performed for sensing when the CA moves the path between the seats 210 with the IC tag reader. FIG. 20 is an explanatory diagram of reading the IC tag while the measurement subject is moving according to the second embodiment. As shown in FIG. 20, CA moves from the seats 1 and 2 side to the seats 9 and 10 side. As the CA moves, the reading of the IC tag 20 by the IC tag reader 30 changes. At that time, the IC tag reader 30 acquires ID information from the IC tag 20 at predetermined time intervals, and adds acquisition time information to the acquired ID information.

  FIG. 21 is an explanatory diagram of determination of reading of an IC tag while the measurement subject is moving according to the second embodiment. As shown in FIG. 21, the reading of the IC tag reader 30 can follow along with the movement of the CA, and the IC tag ID acquired together with the type stamp is recorded.

  As described above, in the to-be-measured person position measurement system 100 according to the second embodiment, the IC tag 20 is affixed to a pamphlet in the passage side seats 1 to 10 among the plurality of seats 202 in the airplane 201. The CA moves along the path of the airplane 201 with the IC tag reader 30. The determination device 50 determines the position of the CA in the airplane 201 based on the ID information and RSSI. Therefore, according to the to-be-measured person position measurement system 200 according to the second embodiment, the action history of CA in the airplane 201 can be grasped.

  Moreover, since the IC tag reader 30 acquires ID information from the IC tag 20 every predetermined time and gives acquisition time information to the acquired ID information, it is possible to grasp the CA's action history corresponding to the time. By grasping the CA's action history in this way, for example, it can be used as a reference for CA work shift planning, personnel adjustment, and the like.

  Furthermore, since the determination apparatus 50 includes the storage unit 60 in which the position of each IC tag 20 is stored, the ID information of the IC tag 20 and the position information (seat position information) are linked to accurately determine the CA action history. I can grasp it.

  The embodiments described above are for facilitating the understanding of the present invention, and are not intended to limit the present invention. Each element included in the embodiment and its arrangement, material, condition, shape, size, and the like are not limited to those illustrated, and can be changed as appropriate. In addition, the structures shown in different embodiments can be partially replaced or combined.

  For example, in the first embodiment, the user's behavior history is sensed for a toilet as a space, but it can also be applied to other type rooms. In addition, in the second embodiment, sensing of the behavior history of the person to be measured is performed on an airplane as a space, but the present invention can also be applied to other forms of transportation such as the Shinkansen.
