  On the other hand, it is assumed that the open / close detection unit 211 determines that the end of use of the refrigerator 3002 by the user has been detected by input of the close detection information (step S708: Yes). In this case, the position specifying unit 3212 specifies the position information indicating the position of the article stored in the refrigerator compartment S1 of the refrigerator 3002 and the type information indicating the type (step S709). Here, when the position specifying unit 3212 specifies the position information and the type information, the refrigerator 3002 sets the lighting method of the light emitting unit 242 to the optimal lighting for specifying the type of the article according to the location to be specified. It is preferable to have a function to change the method. Subsequently, the open / close detection unit 211 transmits the end notification information to the control device 3001, and the position specifying unit 3212 transmits the specified position information and type information to the control device 3001 (step S710). Thereafter, upon receiving the light-off instruction information from the control device 3001 (step S711), the lighting control unit 213 turns off the light-emitting unit 242 of the lighting device 24 (step S712). Thereafter, the process of step S701 is executed again.

  Next, an article storage control process executed by the control device 3001 according to the present embodiment will be described with reference to FIG. The article storage control process is started when, for example, the control device 3001 is turned on. First, the processing from step S301 to step S308 is performed. The processing from step S301 to step S308 is the same as the processing from step S201 to step S208 described in the second embodiment with reference to FIG. Next, the notification information acquisition unit 111 determines whether the end notification information, the position information, and the type information have been received from the refrigerator 3002 (Step S309). As long as the notification information acquisition unit 111 determines that the end notification information, the position information, and the type information have not been received (step S309: No), the processing of step S309 is repeatedly executed.

  On the other hand, the notification information acquisition unit 111 determines that the end notification information, the position information, and the type information have been received from the refrigerator 3002 (step S309: Yes). In this case, the inventory monitoring unit 3116 determines, based on the user information, the position information, and the type information, whether the inventory of the refrigerator compartment S1 of the refrigerator 3002 has changed, that is, whether there has been entry / exit or movement of articles. (Step S310). When the inventory monitoring unit 3116 determines that there has been entry / exit or movement of the article (step S310: Yes), it generates entry / exit flag information as described above, and displays the user information and the date / time when entry / exit was performed. The information is stored in the entry / exit history storage unit 3133 together with the indicated date / time information, the position information and the type information of the entered / exited article (step S311). Subsequently, the process of step S312 described below is performed.

  On the other hand, when the inventory monitoring unit 3116 determines that there is no entry / exit or movement of the article (step S310: No), the command information generation unit 114 generates turn-off command information for commanding to turn off all the light-emitting units 242. To the refrigerator 3002 (step S312). After that, the update unit 2117 updates the position information stored in the article position storage unit 3131 in accordance with the presence or absence of the inventory change determined by the inventory monitoring unit 3116, that is, the presence or absence of entry / exit or movement of the article (step S313). ). Next, the process of step S301 is performed again.

  As described above, in the article storage control system according to the present embodiment, when the notification information acquisition unit 111 acquires the end notification information, the position information acquisition unit 3112 determines the position of the article after acquiring the end notification information. And the type information indicating the type of each article together with the position information indicating the type. Then, the inventory monitoring unit 3116 determines whether there is a change in the inventory of the refrigerator compartment S1 based on the user information, the position information, and the type information. Thereby, when the user moves the position of the article stored in the refrigerator compartment S1 in the refrigerator compartment S1, the lighting mode of the lighting device 24 can be changed accordingly. Therefore, even when an article related to the user is moved in the refrigerator compartment S1, the user's consciousness can be concentrated on the article. Therefore, it is possible to reduce the time required for the user to move articles into and out of the refrigerator 3002.

  The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments. For example, the selection unit of the control device may select lighting mode information of the lighting device based on inventory fluctuation history information indicating a history of inventory fluctuation of the refrigerator specified by the inventory monitoring unit.

  In the article storage control system according to the present modification, for example, as illustrated in FIG. 17, the control device 4001 may include a period determination unit 4118 and a reference period storage unit 4134. In FIG. 17, the same components as those in the second embodiment are denoted by the same reference numerals as those in FIG. The reference period storage unit 4134 stores reference period information indicating a preset reference period for an elapsed period after entry of articles stored in the refrigerator compartment S1.

  The period determination unit 4118 calculates an elapsed period after the entry of each article stored in the refrigerator compartment S1 based on the date and time information stored in the entry / exit history storage unit 2133, and the calculated elapsed period is set in advance. It is determined whether or not it is longer than the reference period. Here, the period determination unit 4118 includes, for example, a software timer, and based on the difference between the date and time indicated by the date and time information stored in the entry and exit history storage unit 2133 and the current date and time, the time to the refrigerator compartment S1 of each article at the current time. Calculate the elapsed time after the storage of the vehicle.

  The selection unit 4113 obtains user information on the user who uses the refrigerator 2002 from the refrigerator 2002, and obtains, by the period determination unit 4118, position information corresponding to an article whose elapsed period after storage is equal to or longer than the reference period. Then, the selection unit 4113 acquires the position information corresponding to the acquired user information from the article position storage unit 2131, and corresponds to the position information corresponding to the user information and the article whose storage period has elapsed after the storage is equal to or longer than the reference period. Lighting mode information corresponding to both the position information, that is, a combination of the light emitting unit identification information is selected.

  Next, an article storage control process executed by the control device 4001 according to the present modification will be described with reference to FIG. In FIG. 18, the same reference numerals are given to the same processes as those in the article storage control process described in Embodiment 2 with reference to FIG. 11. First, when the processes from steps S201 to S204 are performed, the period determination unit 4118 refers to the date and time information stored in the storage and retrieval history storage unit 2133, and determines whether or not each article stored in the refrigerator compartment S1 has been stored. The elapsed time from to is calculated (step S401).

  Next, the period determination unit 4118 acquires the reference time information from the reference period storage unit 4134, and determines whether or not there is an elapsed period equal to or longer than the reference period indicated by the reference time information among the elapsed periods calculated for each article. A determination is made (step S402). Here, if the period determination unit 4118 determines that there is no elapsed period equal to or longer than the reference period in the elapsed period calculated for each article (step S402: No), the process of step S205 is executed as it is.

  On the other hand, it is assumed that the period determination unit 4118 determines that the elapsed period calculated for each article includes an elapsed period equal to or longer than the reference period indicated by the reference time information (step S402: Yes). In this case, the selection unit 4113 additionally acquires the position information of the article corresponding to the elapsed period equal to or longer than the reference period by the period determination unit 4118 (Step S403). After that, the processing after step S205 is executed.

  According to this configuration, the selection unit 4113 turns on the lighting device 24 based on the inventory fluctuation history information stored in the entry / exit history storage unit 2133 indicating the history of inventory fluctuation of the refrigerator 2002 specified by the inventory monitoring unit 2116. Select mode information. Thus, for example, when the user forgets the existence of the article after entering the refrigerator compartment S1 and the article has been left, the user can be notified of the existence of the article. Accordingly, there is an advantage that the article is prevented from being left in the refrigerator 2002 for a long time, and disposal of the article due to expiration of the expiration date is reduced.

  In the first embodiment, as shown in FIG. 2 (A), the refrigerator 2 has a main body 2a having a rectangular box shape with an open front surface and a refrigerating room S1 as an article storage room inside, and an opening of the main body 2a. The example in which the lighting device 24 has the two doors 2b and 2c that cover the portion and is installed on the upper surface of the refrigerator compartment S1 has been described. However, the installation position of the illuminating device 24 is not limited to this, and for example, as shown in FIG. Alternatively, the lighting devices may be dispersedly arranged at three or more locations in the refrigerator compartment S1.

  In each embodiment, for example, as shown in FIG. 20A, a refrigerator is provided with four rectangular plate-shaped light guide plates 5025a, 5025b, and 5025c embedded in rectangular plate-shaped shelves 2aa, 2ab, 2ac, and 2ad, respectively. , 5025d, and light emitting units 5024a, 5024b, 5024c, 5024d arranged opposite to the end faces of the light guide plates 5025a, 5025b, 5025c, 5025d. In this case, the light emitting units 5024a, 5024b, 5024c, and 5024d are arranged on the side surface of the refrigerator compartment S1. Then, when the light emitting units 5024a, 5024b, 5024c, and 5024d are turned on, light incident on the end faces of the light guide plates 5025a, 5025b, 5025c, and 5025d from the light emitting units 5024a, 5024b, 5024c, and 5024d becomes light guide plates 5025a, 5025b, and 5025c. , 5025d, and exits in the thickness direction of the light guide plates 5025a, 5025b, 5025c, 5025d. Thus, it is possible to illuminate the articles placed on the shelves 2aa, 2ab, 2ac, and 2ad. In the example shown in FIG. 20A, four light guide plates 5025a, 5025b, 5025c, and 5025d having the same size are arranged so as to divide the shelves 2aa, 2ab, 2ac, and 2ad into four parts. The number of light guide plates is not limited to four. For example, a plurality of light guide plates having the same size may be arranged so as to divide the shelves 2aa, 2ab, 2ac, and 2ad into six or more.

  Alternatively, for example, as shown in FIG. 20 (B), the refrigerator includes two rectangular plate-shaped light guide plates 6025a and 6025d embedded in each of the shelves 2aa, 2ab, 2ac and 2ad, and two flat-view L-shaped light guide plates. A light guide plate 6025b, 6025c, and a light emitting unit 6024a, 6024b, 6024c, 6024d disposed opposite to an end face of each light guide plate 6025a, 6025b, 6025c, 6025d may be provided. In this case, the light emitting units 6024a, 6024b, 6024c, and 6024d are arranged, for example, on the back surface of the refrigerator compartment S1. According to this configuration, since the light emitting units 6024a, 6024b, 6024c, and 6024d can be integrated on the back side of the refrigerator compartment S1, the light emitting units 6024a, 6024b, 6024c, and 6024d can be compared with the refrigerator according to FIG. Wiring can be simplified. In the example shown in FIG. 20B, the light guide plates 6025a, 6025b, 6025c, and 6025d are arranged so as to divide each shelf 2aa, 2ab, 2ac, and 2ad into four, but the number of light guide plates is four. It is not limited to. For example, the refrigerator 2 may include shelves 2aa, 2ab, 2ac, and 2ad in which five or more or three or less light guide plates are embedded. Further, for example, as shown in FIG. 20C, the refrigerator includes three rectangular plate-like light guide plates 7025a, 7025c, and 7025g embedded in the shelves 2aa, 2ab, 2ac, and 2ad, respectively, and four plain-view L-shapes. , Light-emitting portions 7024a, 7024b, 7024c, 7024d, 7024e, 7025b, 7025b, 7025b, 7025c, 7025d, 7025e, 7025f, 7025g, and light-emitting portions 7024a, 7024b, 7024c, 7024d, 7024e, 7024f and 7024g. The shelves 2aa, 2ab, 2ac, and 2ad shown in FIGS. 20A to 20C are covered with an opaque sheet member (not shown) on the lower surface or the upper surface, so that the shelves 2aa, Light may be emitted only to one side in the thickness direction of 2ab, 2ac, 2ad.

  In each embodiment, the refrigerator may include, for example, shelves 8002aa, 8002ab, 8002ac, and 8002ad including light-emitting units 8024a and 8024b, as illustrated in FIG. In the shelves 8002aa, 8002ab, 8002ac, and 8002ad, the left side in FIG. The light emitting section 8024a is provided at the tip end 8020b of the shelves 8002aa, 8002ab, 8002ac, and 8002ad, and emits light toward the rear side in the refrigerator compartment S1. The light emitting section 8024b is embedded in a flat main body section 8020a of the shelves 8002aa, 8002ab, 8002ac, and 8002ad. Thereby, it becomes easy to illuminate the articles arranged on the back side of the refrigerator compartment S1. Note that the light emitting units 8024a and 8024b may be provided one by one for one region to be illuminated, or a plurality of light emitting units may be provided for one region. In addition, a long light diffusion plate is arranged so as to block the light emission direction of the light emitting units 8024a and 8024b, thereby realizing a light source that emits light linearly along the tips of the shelves 8002aa, 8002ab, 8002ac, and 8002ad. Is also good.

  In each embodiment, the refrigerator may include a light guide plate (not shown) provided in a part of the pockets 2ba, 2bb, 2bc, 2ca, 2cb, 2cc. When the light guide plate is long and is provided along the upper ends of the pockets 2ba, 2bb, 2bc, 2ca, 2cb, and 2cc, the light guide plate is provided at the upper ends of the pockets 2ba, 2bb, 2bc, 2ca, 2cb, and 2cc. It emits light linearly along.

  In each embodiment, the lighting control unit 213 of the refrigerator may light the lighting device 24 intermittently. In this case, the user can easily notice the position of the article related to the user.

  In each embodiment, the acquisition of the position information indicating the position of the article stored in the refrigerator compartment S1 by the position information acquisition unit and the selection of the lighting mode information by the selection unit are performed by the user once for the doors 2b and 2c. The case where each of the operations is performed only once for the opening / closing operation has been described. However, the present invention is not limited to this. For example, in response to a single opening and closing operation of the doors 2b and 2c by the user, the position information acquisition unit acquires position information indicating the position of the articles stored in the refrigerator compartment S1, and the selection unit The selection of the lighting mode information may be executed a plurality of times. Alternatively, the position specifying units 212 and 3212 of the refrigerators 2, 2002 and 3002 may specify the position of the article at predetermined time intervals. Further, in the third embodiment, when the inventory monitoring unit determines that the article in the refrigerator compartment S1 has moved while the doors 2b and 2c of the refrigerator 3002 are open, the selecting unit 2113 determines the position of the article after the movement. Lighting mode information corresponding to the information may be selected and transmitted to the refrigerator 3002. In this case, in the refrigerator 3002, the lighting device 24 lights up in different lighting modes following the movement of the articles in the refrigerator compartment S1.

  In the article storage control system according to Embodiments 2 and 3, the user's article is extracted by extracting image information of the article held by the user from the image of the user captured by the external imaging section 2023. May be provided with a user intention determination unit that determines the intention of entering the warehouse. And the selection part 2113 may select lighting mode information based on the determination result by the user intention determination part. The article storage control system according to the second and third embodiments further includes a timing specifying unit that specifies a timing at which the user enters the article based on the date and time information stored in the entry / exit history storage unit 2133. The unit 2113 may select the lighting mode information according to the timing at which the user specified by the timing specifying unit enters the warehouse. Further, in the article storage control system according to each embodiment, the inventory in the refrigerator compartment S1 is large, and the refrigerator 2, 2002, 3002 is vacant in the back of the refrigerator compartment S1 which is hard to be seen by the user from outside. If there is a space, the selection units 113 and 2113 may select a lighting mode that illuminates an empty space in the back of the refrigerator compartment S1. Here, the selection units 113 and 2113 have, for example, a stock in the refrigerator compartment S1 and an empty space in the back of the refrigerator compartment S1 based on the position information of the article acquired by the position information acquisition units 112, 2112, and 3112. It may be determined whether or not this is the case. According to this configuration, the time required for a user to search for an empty space when articles are stored in the refrigerator compartment S1 is reduced. Thereby, the fluctuation of the temperature in the refrigerator compartment S1 can be minimized, so that the influence of the temperature fluctuation on other articles existing in the refrigerator compartment S1 is suppressed. Further, an effect of minimizing the energy required to return the fluctuating temperature in the refrigerator compartment S1 to the original temperature can be expected.

  In the article storage control system according to the second and third embodiments, for example, in the case where article retrieval and retrieval are continuously performed within a preset period, the selection unit 2113 is in a state in which the articles are received. May be transmitted to the refrigerators 2002 and 3002 continuously. In this case, in the refrigerators 2002 and 3002, the lighting device 24 continuously illuminates the position where the ejected article is stored for a preset time after the article is ejected. According to the present configuration, for example, when the user instructs the supervised person to temporarily move the articles in and out of the refrigerators 2002 and 3002, the supervised person sets the place where the articles are returned to the refrigerator compartment S1. Has the advantage that it can be transmitted in an easy-to-understand manner.

  In each embodiment, the correspondence information stored in the correspondence storage unit 132 may be appropriately changeable by a user. Refrigerators 2, 2002, and 3002 according to the embodiments each include an operation unit (not shown) for changing the correspondence information stored in the correspondence storage unit 132 of the control device 1, 2001, or 3001. It may be. Alternatively, the article storage control system can communicate with the control devices 1, 2001, and 3001 via the network NT, accept an operation by the user, and indicate a change in the correspondence information in accordance with the accepted operation. A terminal device (not shown) that transmits change command information including content information to the control devices 1, 2001, and 3001 may be provided. In this case, upon receiving the change command information from the terminal device, the control devices 1, 2001, and 3001 change the correspondence information stored in the correspondence storage unit 132 based on the change content information included in the change command information. do it.

  In the second and third embodiments, the example in which the user information specifying unit 214 specifies the user information after the open / close detecting unit 211 transmits the start notification information to the control devices 2001 and 3001 has been described. However, the present invention is not limited to this. For example, the user information identification unit 214 may identify the user information before the opening / closing detection unit 211 transmits the start notification information to the control devices 2001 and 3001. .

  In the second and third embodiments, the example in which the user information specifying unit 214 specifies the user information of the user of the refrigerator 2002 based on the image information indicating the image captured by the external image capturing unit 2023 has been described. . However, the present invention is not limited to this. For example, it is assumed that the refrigerator includes a fingerprint sensor for detecting a user's fingerprint or a biological information reading unit for reading biological information such as veins, voice prints, and irises. In this case, the user information specifying unit 214 converts the user information of the user of the refrigerator 2002 based on the fingerprint information indicating the fingerprint of the user detected by the fingerprint sensor or the biometric information read by the biometric information reading unit. It may be specified. Alternatively, when the refrigerator is provided with an IC card reader that reads information about the user when the user holds the IC card, the user information identification unit 214 determines the information based on the information about the user read by the IC card reader. It may specify user information. Alternatively, when the refrigerator includes a key input unit, the user information specifying unit 214 may specify user information based on a pass key input by the user via the key input unit. Note that the user information specifying unit 214 may have another configuration as long as the user information specifying unit 214 can satisfy the granularity related to user recognition required in the article storage control system. Here, the granularity of the recognition of the user is, for example, the gender, age, affiliation group, whether or not the user is registered, or the individual can be uniquely specified, for example.

  In the second and third embodiments, the selecting unit 2113 determines whether or not the result of the image analysis of the captured image captured by the external imaging unit 2023 or the information indicating the age or height of the user associated with the user information. It may be determined whether or not the user is a short child. And the selection part 2113 may select lighting mode information according to whether a user is a short child.

  In the second and third embodiments, the selection unit 2113 stores and retrieves the last article by the same user in the refrigerator compartment S1 based on the history of the entry / exit flag information stored in the entry / exit history storage units 2133, 3133, for example. The lighting mode information for illuminating the place where the lighting is performed may be selected. Alternatively, the selection unit 2113 specifies a position where the same user frequently moves in and out of articles by the same user based on the history of the entry / exit flag information stored in the entry / exit history storage units 2133 and 3133, for example. Lighting mode information for illuminating only the information may be selected. According to this configuration, since the user's consciousness can be concentrated on the place where the user frequently enters and leaves the articles, the article entry and exit time in the refrigerators 2002 and 3002 can be reduced.

  In Embodiments 2 and 3, the selection unit 2113 uses the user information and the usage corresponding to the user information based on the history of the entry / exit flag information or the date / time information stored in the entry / exit history storage units 2133, 3133, for example. It is also possible to specify the tendency of entry and exit of articles according to the day of the week or time of the person, and select the lighting mode information based on the specified tendency. The selection unit 2113 selects, for example, the lighting mode information for illuminating the place where the ingredients or seasonings are stored, when the user is a cook and the time to use the refrigerators 2002 and 3002 is a time period before dinner. I do. In addition, for example, when the user is an adult and the time to use the refrigerators 2002 and 3002 is a time period after dinner, the selection unit 2113 selects a lighting mode that illuminates a place where sake or a knob is stored. Further, for example, when the user is a minor and the time to use the refrigerators 2002 and 3002 is a time period after dinner, the selection unit 2113 may transmit lighting mode information for illuminating a place where dessert or sweet food is stored. elect. In addition, the selection unit 2113 specifies, for example, articles having a high frequency of entry and exit by the user based on the entry / exit flag information and the history of date and time information stored in the entry / exit history storage units 2133 and 3133, and identifies the identified articles. Select lighting mode information to illuminate. Further, when the selection unit 2113 determines that the frequency of the user entering and leaving the article in the morning time is high based on the history of the entry / exit flag information and the date / time information stored in the entry / exit history storage units 2133 and 3133, Lighting mode information for illuminating the cooked food stored in the refrigerator compartment S1 is selected. Further, in each embodiment, the selection units 113 and 2113 may select the lighting mode regardless of whether or not the notification information acquisition unit 111 acquires the start notification information. In this case, the command information generating unit 114 provides the lighting command information for instructing to turn on the lighting device 24 in the lighting mode already selected by the selecting units 113 and 2113 when the notification information obtaining unit 111 obtains the start notification information. Should be generated.

  In Embodiments 2 and 3, the granularity of user recognition is set for each group to which the user belongs, and the selection unit 2113 selects lighting mode information for illuminating a predetermined location of the refrigerator compartment S1 for each group. May be used. Alternatively, the selection unit 2113 may select the lighting mode information that illuminates only the places where members of the same group have previously entered and exited the warehouse in the refrigerator compartment S1. According to this configuration, the user can easily and intuitively understand the place used by the group to which the user belongs in the refrigerator compartment S1. Therefore, when using the refrigerators 2002 and 3002, the user searches for a place where goods should be stored. In addition, there is an advantage that the time required for other members belonging to the same group to search for articles stored is reduced.

  In the third embodiment, an example has been described in which the position specifying unit 3212 specifies type information of an article based on image information indicating a captured image captured by the internal imaging unit 3023. However, the present invention is not limited to this. For example, when the refrigerator 3002 is provided with an RFID tag reader that reads an RFID tag attached to an article, the position specifying unit 3212 determines the product name, type, and product included in the information of the RFID tag read by the RFID tag reader. The type information of the article may be specified based on information such as a code. Here, information such as the product name, type, and product code necessary for the position specifying unit 3212 to specify the type information of the product may be stored in the auxiliary storage unit 103 in advance, or the network NT And may be obtained from an external device via.

  In each embodiment, the association between the position information indicating the position of the article stored in the refrigerator compartment S1 and the user information is performed, for example, by attaching an RFID tag in which the user information is recorded before the article is stored to the article. It may be performed by mounting. Alternatively, a tape displaying the name of the user or a mark unique to the user is attached to the article before entering the article, and then the article is entered into the refrigerator compartment S1 while being photographed by the internal imaging section 3023, or the article is refrigerated. After entering the room S1, the recording may be performed by causing the internal imaging unit 3023 to image the tape. Alternatively, before the articles enter the refrigerator compartment S1, an RFID tag is attached to the articles, and the result of reception by a transceiver (not shown) that executes communication with the RFID tags provided in the refrigerator 2 by the position specifying unit is provided. , The position of the article may be specified. Various position detection methods using RFID tags have been proposed. In the present invention, these various proposed position detection methods can be adopted.

  In each embodiment, control devices 1, 2001, and 3001 may be incorporated in refrigerators 2, 2002, and 3002. In this case, the control devices 1, 2001, and 3001 may execute microcomputer-to-microcomputer and board-to-board communication such as UART between the control units 21, 2021, and 3021 of the refrigerators 2, 2002, and 3002.

  In each embodiment, the control device 1, 2001, 3001 may be able to communicate with a plurality of refrigerators 2, 2002, 3002.

  In each embodiment, the position information may be coordinate information indicating the coordinates of the space in the refrigerator compartment S1. In this case, the correspondence storage unit may store, for example, the light emitting unit identification information of each light emitting unit and coordinate information indicating the coordinates of the space in the refrigerator compartment S1 illuminated by each light emitting unit in association with each other. .
