(First embodiment)
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a first embodiment of the invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating a configuration example of a layout system according to the first embodiment. As shown in FIG. 1, the layout system according to the first embodiment includes a layout cart 10, a wireless access point 20, a control device 30, and a corridor lamp 40. The catering system of this embodiment is installed in a hospital or a nursing facility, for example. Below, the installation example to a hospital room is demonstrated.

  The layout cart 10 includes a plurality of tray storage shelves 10A to 10D that store a plurality (in the present embodiment, four as an example) of trays 11A to 11D. The distribution cart 10 detects that the distribution trays 11A to 11D have been removed from the tray storage shelves 10A to 10D, and identifies a tray ID (tray identification information) for identifying the distribution trays 11A to 11D from which the removal has been detected. Has a function of wirelessly transmitting. The take-out detection function of the trays 11A to 11D for layout is realized by the IC tags 12A to 12D and the tag readers 13A to 13D.

  In other words, IC tags 12A to 12D storing tray IDs are respectively installed on the trays 11A to 11D for layout arranged in the tray storage shelves 10A to 10D. These IC tags 12A to 12D are RFID (Radio Frequency Identification) tags capable of reading a tray ID by wireless communication. The IC tags 12A to 12D need only be installed on the layout trays 11A to 11D, and various specific installation methods can be applied. For example, it may be embedded in the bottom of the trays 11A to 11D for serving. Alternatively, the IC tags 12A to 12D may be placed as food tags on the trays 11A to 11D for serving.

  On the other hand, tag readers 13 </ b> A to 13 </ b> D are embedded in the bottoms of the tray storage shelves 10 </ b> A to 10 </ b> D at or near positions where the trays 11 </ b> A to 11 </ b> D are placed. The tag readers 13A to 13D read the tray IDs stored in the IC tags 12A to 12D by performing short-range wireless communication with the IC tags 12A to 12D installed on the trays 11A to 11D for layout. The tag readers 13 </ b> A to 13 </ b> D are connected to the wireless access point 20 via a wireless LAN such as Wi-Fi, and transmit the tray ID read from the IC tags 12 </ b> A to 12 </ b> D to the wireless access point 20.

  When the trays 11A to 11D are placed on the tray storage shelves 10A to 10D, the IC tags 12A to 12D installed on the trays 11A to 11D and the tag readers installed on the tray storage shelves 10A to 10D. 13A to 13D are within a communicable range of short-range wireless communication.

The installed tag readers 13 </ b> A to 13 </ b> D are outside the communicable distance range of short-range wireless communication. For this reason, the tag readers 13A to 13D cannot enter the tray ID from the IC tags 12A to 12D.

  Therefore, when the tag readers 13A to 13D read the tray ID from the IC tags 12A to 12D and change to a state where the tray ID cannot be read, the layout trays 11A to 11D are taken out from the tray storage shelves 10A to 10D. Can be detected. When any of the four layout trays 11A to 11D is taken out from the tray storage shelves 10A to 10D, the tag reader of the tray storage shelf on which the removed layout tray is placed is the IC of the layout tray. The tray ID read from the tag is transmitted to the wireless access point 20.

  The control device 30 communicates with the distribution cart 10 via the wireless access point 20 and notifies to whom the distribution trays 11A to 11D should be distributed based on the tray ID sent from the distribution cart 10. To control. As this control device 30, it is possible to use a nurse call parent device or a control device generally used in a nurse call system. In 1st Embodiment, the control apparatus 30 alert | reports with respect to the corridor lamp 40 installed for every hospital room in a hospital.

Further, the layout cart 10 'includes tag readers 13A' to 13D 'instead of the tag readers 13A to 13D shown in FIG.

  In the second embodiment, the light emission control IC 15 and the wireless access point 20 are used as a current position detection unit of the layout cart 10 '. In this case, the wireless access point 20 is installed for each hospital room in the hospital. Specifically, the wireless access point 20 corresponding to the hospital room at the stop position and the light emission control IC 15 perform wireless communication in a state where the catering cart 10 'is stopped at a position where the display of the corridor lamp 40 of a hospital room can be seen. A wireless access point 20 is installed for each hospital room.

  The light emission control IC 15 periodically wirelessly transmits the cart ID stored in the internal memory via the wireless LAN. When the wireless access point 20 receives the cart ID transmitted from the light emission control IC 15, the wireless access point 20 transmits the cart ID together with the SSID (Service Set Identifier) for identifying itself to the control device 30 '. Based on the SSID of the wireless access point 20, the current position of the serving cart 10 'is detected by the control device 30'.

  In addition, the light emission control IC 15 communicates with the tag readers 13A ′ to 13D ′ installed in the tray storage shelves 10A to 10D, and which tray ID the tag readers 13A ′ to 13D ′ read from the IC tags 12A to 12D. To figure out. Then, as a response to the transmission of the cart ID from the light emission control IC 15 as described above, the distribution tray corresponding to the tray ID is sent in accordance with the light emission control instruction sent from the control device 30 ′ including the tray ID. The light emission of the light emitting units 14A to 14D at the placed positions is controlled.

  FIG. 6 is a block diagram illustrating a functional configuration example of the layout system according to the second embodiment. Here, functional configuration examples of the tag reader 13A ', the light emission control IC 15 and the control device 30' are shown. In FIG. 6, those given the same reference numerals as those shown in FIG. 2 have the same functions, and therefore redundant description is omitted here. Since the four tag readers 13A 'to 13D' all have the same configuration, only the configuration of one tag reader 13A 'is shown as a representative.

  As shown in FIG. 6, the tag reader 13 </ b> A ′ according to the second embodiment further includes a tray identification information notification unit 23 in addition to the functional configuration shown in FIG. 2. The light emission control IC 15 according to the second embodiment includes a cart ID transmission unit 51 and a light emission control unit 52. The control device 30 ′ according to the second embodiment further includes a cart ID reception unit 61, a room detection unit 62, a tray identification information extraction unit 63, and a light emission control unit 64 in addition to the functional configuration shown in FIG. Yes. Further, the control device 30 ′ includes a correspondence information storage unit 31 ′ instead of the correspondence information storage unit 31.

  The tray identification information notification unit 23 of the tag reader 13A 'notifies the light emission control unit 52 of the light emission control IC 15 of the tray ID read from the IC tag 12A. For example, the light emission control IC 15 and the tag readers 13A ′ to 13D ′ are connected by wired wiring, and the tray identification information notification unit 23 notifies the tray ID to the light emission control unit 52 of the light emission control IC 15 via this wiring. To do. Thereby, the light emission control part 52 acquires tray ID which tag reader | leader 13A'-13D 'of each tray storage shelf 10A-10D read from IC tag 12A-12D. And the light emission control part 52 matches each acquired tray ID with each tray storage shelf 10A-10D, and memorize | stores it in the memory which is not shown in figure.

  As described above, the cart ID transmission unit 51 of the light emission control IC 15 periodically wirelessly transmits the cart ID stored in the internal memory (not shown). When the wireless access point 20 receives the cart ID transmitted from the cart ID transmission unit 51, the wireless access point 20 transmits the cart ID together with its own SSID to the control device 30 '. The cart ID receiving unit 61 of the control device 30 ′ receives the cart ID and SSID transmitted by the cart ID transmitting unit 51.

  The correspondence information storage unit 31 ′ of the control device 30 ′ includes each tray in which each patient is hospitalized in addition to the correspondence between the tray ID of each layout tray and the patient (bed number) to which each layout tray is to be served. A room number of a hospital room and a tray ID of a tray for serving in each hospital room are stored in association with each other. The correspondence information storage unit 31 'corresponds to a correspondence information storage unit and a second correspondence information storage unit.

  FIG. 7 is a diagram illustrating an example of correspondence information stored in the correspondence information storage unit 31 ′. In FIG. 7, in addition to the tray ID and bed number shown in FIG. 3, the room number of the hospital room is stored in association with each other. Thereby, in addition to the association between the tray ID and the bed number, the association between the tray ID and the room number is made.

  Based on the SSID of the wireless access point 20 received by the cart ID reception unit 61, the room detection unit 62 detects the hospital room where the serving cart 10 'is currently located. In other words, the room detection unit 62 detects that the catering cart 10 'currently exists in the hospital room where the wireless access point 20 indicated by the SSID is installed. Information stored in association with the SSID and the room number is stored in a storage unit (not shown).

  Note that since the cart ID transmission unit 51 of the light emission control IC 15 periodically transmits the cart ID, even if the serving cart 10 ′ is moving, if the wireless access point 20 exists nearby, the wireless access point 20 Receives the cart ID and transmits it to the control device 30 ′ together with the SSID. Therefore, the room detector 62 of the control device 30 ′ needs to be devised so as not to detect the hospital room in which the layout cart 10 ′ currently exists based on the SSID sent during the movement of the layout cart 10 ′. For example, when the same SSID is continuously received more than a predetermined number of times, it is possible to determine that the serving cart 10 ′ currently exists in the hospital room where the wireless access point 20 indicated by the SSID is installed. .

  The tray identification information extraction unit 63 extracts the tray ID corresponding to the room number of the hospital room detected by the room detection unit 62 from the correspondence information storage unit 31 ′. Here, when there are a plurality of tray IDs corresponding to the room number detected by the room detection unit 62, the tray identification information extraction unit 63 extracts the plurality of tray IDs from the correspondence information storage unit 31 '.

  The light emission control unit 64 of the control device 30 ′ includes a tray identification among the light emission units 14A to 14D installed on the tray storage shelves 10A to 10D of the layout cart 10 ′ indicated by the cart ID received by the cart ID reception unit 61. Control is performed so that the light emitting unit provided on the tray storage shelf on which the tray for tray specified by the tray ID extracted by the information extracting unit 63 is placed emits light.

  Specifically, the light emission control unit 64 identifies the light emission control IC 15 of the layout cart 10 ′ indicated by the cart ID received by the cart ID reception unit 61 by the tray ID extracted by the tray identification information extraction unit 63. An instruction command for causing the light emitting units 14A to 14D provided on the tray storage shelf on which the serving tray is placed to transmit light is transmitted. This instruction command includes the tray ID extracted by the tray identification information extraction unit 63.

  In accordance with the instruction command sent from the light emission control section 64 of the control device 30 ′, the light emission control section 52 of the light emission control IC 15 is the position where the layout tray corresponding to the tray ID included in the instruction command is placed. The light emission units 14A to 14D are controlled. As described above, the light emission control unit 52 associates the tray IDs read by the tag readers 13A ′ to 13D ′ of the tray storage shelves 10A to 10D from the IC tags 12A to 12D with the tray storage shelves 10A to 10D in the memory. I remember it. Therefore, by comparing the information in the memory with the tray ID included in the instruction command, it is possible to grasp the positions of the tray storage shelves 10A to 10D that should emit the light emitting units 14A to 14D. .
