On the other hand, when the inventory monitoring unit 3116 determines that there is no goods entering/leaving or moving (step S310: No), the command information generation unit 114 generates light-off command information instructing to turn off all the light emitting units 242. is sent to refrigerator 3002 (step S312). After that, the update unit 2117 updates the position information stored in the article position storage unit 3131 according to the presence or absence of inventory fluctuations determined by the inventory monitoring unit 3116, that is, the presence or absence of movement of goods in and out of the warehouse (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 section 111 acquires end notification information, the position information acquisition section 3112 determines the position of the article after acquiring the end notification information. The type information indicating the type of each article is acquired together with the position information indicating the. 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. Accordingly, when the user moves the position of the article stored in the refrigerating compartment S1 within the refrigerating compartment S1, the lighting mode of the lighting device 24 can be changed accordingly. Therefore, even if an article related to the user is moved within the refrigerating compartment S1, the user's attention can be focused on the article. Therefore, it is possible to shorten the time required for the user to put articles in and out of the refrigerator 3002 .

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. For example, the selection unit of the control device may select the lighting mode information of the lighting device based on the inventory change history information indicating the history of inventory changes of refrigerators identified by the inventory monitoring unit.

In the article storage control system according to this modification, for example, as shown in FIG. In addition, in FIG. 17, the same reference numerals as in FIG. 7 denote the same configurations as in the second embodiment. The reference period storage unit 4134 stores reference period information indicating a preset reference period for the elapsed period after the goods stored in the refrigerator compartment S1 are stored.

The period determining unit 4118 calculates the elapsed period after the storage of each article stored in the refrigerating room S1 based on the date and time information stored in the storage/retrieving history storage unit 2133, and the calculated elapsed period is set in advance. It is determined whether or not it is longer than or equal to the reference period. Here, the period determination unit 4118 has, 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 storage/retrieval history storage unit 2133 and the current date and time, the items to be stored in the refrigerator compartment S1 at the current time. Elapsed time after warehousing is calculated.

The selection unit 4113 acquires user information about the user who uses the refrigerator 2002 from the refrigerator 2002, and acquires the position information corresponding to the article for which the elapsed time since entering the warehouse is longer than or equal to 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 selects the position information corresponding to the user information and the article for which the elapsed period after warehousing is equal to or longer than the reference period. A combination of lighting mode information corresponding to both the position information, that is, the light emitting unit identification information is selected.

Next, article storage control processing executed by the control device 4001 according to this modification will be described with reference to FIG. In FIG. 18, the same reference numerals are assigned to the same processes as the article storage control process described with reference to FIG. 11 in the second embodiment. First, when the processes from steps S201 to S204 are executed, the period determination unit 4118 refers to the date and time information stored in the storage/retrieval history storage unit 2133, and determines whether each item stored in the refrigerating room S1 after storage has been stored. to the present time 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 item. Determine (step S402). Here, when the period determination unit 4118 determines that there is no elapsed period equal to or longer than the reference period among the elapsed periods calculated for each item (step S402: No), the process of step S205 is executed as it is.

On the other hand, it is assumed that the period determining unit 4118 determines that the elapsed period calculated for each item 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 processes after step S205 are executed.

According to this configuration, the selection unit 4113 turns on the lighting device 24 based on the inventory change history information stored in the storage/delivery history storage unit 2133, which indicates the history of the inventory change of the refrigerator 2002 specified by the inventory monitoring unit 2116. Pick mode information. As a result, for example, when the user forgets the existence of the article after the article is stored in the refrigerating compartment S1 and the article is left unattended, the existence of the article can be notified to the user. Therefore, there is an advantage that it is possible to prevent articles from being left in the refrigerator 2002 for a long period of time and, for example, it is possible to reduce the disposal of articles due to the expiry of the expiration date.

It may be specified. Alternatively, if the refrigerator is equipped with an IC card reader that reads information about the user when the IC card is held up by the user, the user information specifying unit 214 may, based on the information about the user read by the IC card reader, It may specify user information. Alternatively, if the refrigerator has a key input unit, the user information specifying unit 214 may specify user information based on a passkey input by the user via the key input unit. It should be noted that the user information specifying unit 214 may have another configuration as long as it can satisfy the granularity of user recognition required in the article storage control system. Here, the granularity of user recognition is, for example, the user's sex, age, belonging group, whether or not the user is registered, or the ability to uniquely identify an individual.

In Embodiments 2 and 3, the selection unit 2113 performs image analysis of the captured image captured by the external imaging unit 2023, or based on 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. Then, the selection unit 2113 may select lighting mode information according to whether the user is a short child.

In Embodiments 2 and 3, the selection unit 2113 determines whether the same user previously entered/exited an article in the refrigerator compartment S1 based on the history of the entry/exit flag information stored in the entry/exit history storage units 2133 and 3133, for example. The lighting mode information may be selected to illuminate the location. Alternatively, the selecting unit 2113 identifies a position where the same user frequently enters and exits an article based on the history of the entry/exit flag information stored in the entry/exit history storage units 2133 and 3133, for example, and identifies the identified location. The lighting mode information may be selected to illuminate only the . According to this configuration, it is possible to focus the user's attention on the place where the user frequently puts in/out the articles, so that the time for putting in/out the articles in the refrigerators 2002 and 3002 can be shortened.

In Embodiments 2 and 3, the selection unit 2113 selects 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 and 3133, for example. It is also possible to identify the tendency of goods entering and leaving the warehouse according to the day of the week or the time of day of the person, and select the lighting mode information based on the identified tendency. For example, if the user is a person in charge of cooking and the time at which the refrigerators 2002 and 3002 are used is before dinner, the selection unit 2113 selects lighting mode information for illuminating the place where ingredients or seasonings are stored. do. For example, if the user is an adult and the refrigerators 2002 and 3002 are used after dinner, the selection unit 2113 selects the lighting mode for lighting the place where alcoholic beverages or snacks are stored. Further, if the user is a minor and the time when the refrigerators 2002 and 3002 are used is after dinner, the selection unit 2113 selects lighting mode information for lighting the place where desserts or sweet foods are stored. elect. Further, the selection unit 2113 identifies articles frequently entered/exited by the user based on the history of entry/exit flag information and date/time information stored in the entry/exit history storage units 2133 and 3133, for example, and selects the identified articles. The lighting mode information for lighting is selected. Furthermore, when the selection unit 2113 determines that the user frequently enters and leaves the warehouse in the morning 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 lighting 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 the notification information acquisition unit 111 acquires the start notification information. In this case, the command information generation unit 114 generates lighting command information for instructing the lighting device 24 to light in the lighting mode already selected by the selection units 113 and 2113 at the time when the notification information acquisition unit 111 acquires the start notification information. should be generated.

In Embodiments 2 and 3, the user's recognition granularity is set for each group to which the user belongs, and the selection unit 2113 selects lighting mode information for lighting a predetermined place in the refrigerator compartment S1 for each group. It may be something to do. Alternatively, the selection unit 2113 may select lighting mode information that illuminates only locations in the refrigerating compartment S1 where members of the same group have entered and exited in the past. According to this configuration, the user can intuitively understand the location of the group to which he/she belongs in the refrigerating compartment S1. , there is an advantage that the time required for searching for articles that have been stored by other members belonging to the same group can be shortened.

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