Description

  The present invention relates to a food purchase management support system that supports from food management to purchase using an IC chip and RFID (Radio Frequency Identification).

  With the development of technology and cost reduction of IC cards, mobile terminals, and IC chips mounted on RFID, in recent years, IC cards and IC chips such as RFID have become widespread. Recently, an RFID tag is mounted on a book owned by a library, and a book inventory management and lending management system is performed. Also, in convenience stores, supermarkets, etc., a shopping navigation cart that can refer to the recipe of the corresponding food by mounting the RFID tag on the food for sale and reading the RFID tag into the reader / writer of the IC chip provided in the shopping cart. There is a system.

  The shopping navigation cart system will be briefly described. As shown in FIG. 17, in the shopping navigation cart system, an RFID tag 82 is mounted on a food shelf 81 on which food is displayed. When the RFID tag of the food shelf 81 is read by the RFID tag reader / writer 83, the target recipe information is acquired from the recipe information storage unit 85 based on the food information read by the recipe information acquisition unit 84. Recipe information acquired from the recipe information storage unit 85 is transferred to the recipe information display unit 86, and the recipe information is displayed on a display means such as a display provided in the shopping navigation cart.

Furthermore, service demonstration experiments such as EXPRESS POS have been conducted in which RFID tags for foods in shopping carts are read in a batch and the total amount of foods is calculated to reduce the time to purchase products.
Here, an overview of EXPRESS POS will be described. As shown in FIG. 18, when the food group 86 on which the RFID tag is mounted is brought close to the RFID tag reader / writer 87, the amounts of all foods and the food names that are close to the RFID tag reader / writer 87 are calculated. Transmitted to the unit 88. The total amount calculation unit 88 calculates the total of each amount transmitted from the RFID tag reader / writer 87 and transmits it to the total amount display unit 89. The total amount display unit 89 displays the amount of each food item and the total amount of all food items.

As documents disclosing such technology, there are the following known technical documents.

  However, in the shopping navigation cart described above, it is possible to refer to recipe information of food sold only when actually going to the store. For this reason, consumers cannot take into account information about foods present at home. Therefore, the consumer needs to confirm in advance the food remaining in the refrigerator at home. As a consumer, when checking the food remaining in the refrigerator at home, the customer often goes to the store after considering the recipe and deciding which food to purchase.

  In the case of changing the food to be purchased when going to a store or purchasing a new food, there are many cases where special food is present at the store. Therefore, in order to purchase foods that are not planned to be purchased at the beginning, the foods in the refrigerator at home may not be used, but the expiration date may be expired and may be discarded. In addition, even if the consumer checks the food remaining in the refrigerator at home, the consumer may go to the store and forget the food to purchase, and may have to return to the store and purchase again.

  An object of the present invention is to determine a recipe based on information on food stored in a refrigerator while the consumer is at home, expiration date of the food, information on food sold at a store, and the like. In addition, by storing and using information related to food to be purchased in the IC card of the store member's card or the IC chip of the mobile terminal, it is possible to prevent forgetting to purchase the food to be purchased or to purchase more food than necessary. It is to provide a food purchase management support system that makes it possible to shorten the shopping time.

  In order to achieve the above object, a food purchase management support system according to the present invention includes a refrigerator that stores and stores food, a server that is communicably connected to the refrigerator via a network, A mobile storage device for storing information about food, an IC chip reader / writer that reads information about food stored in the mobile storage device, and a cart for storing and transporting food in a store; A food purchase management support system comprising: a storage unit in which a database for managing recipe information for each food and a database for managing food information on food sold at the store are registered. The refrigerator has an RFID tag reader / writer that reads an RFID tag mounted on the food, and is stored in the refrigerator.

To do.

The food purchase management support system of the present invention has the following effects.
-An appropriate recipe can be selected based on the food in the refrigerator, the expiration date of the food, and the information on the special sale food in the store.
・ Determine the food you want to purchase at the consumer's home, store it in the IC card or IC chip of the mobile terminal, etc., and link it with the cart to prevent you from forgetting to purchase the food you plan to purchase Since the user is guided to the place where the purchased food is displayed, the purchase time of the consumer can be shortened. In addition, it is possible to reduce purchases of foods other than those scheduled in advance, and to reduce foods such as expiration dates.

Hereinafter, an embodiment of a food purchase management support system to which the present invention is applied will be described.
As shown in FIG. 1, the food purchase management support system in the present embodiment includes a refrigerator 11 installed in a home, a mobile storage device 12, a server 13, and a cart 15 provided in a store 14. Has been. The refrigerator 11 and the server 13 are connected so as to be able to communicate with each other via the Internet 16 as a network.

  The refrigerator 11 refrigerates and manages the purchased food. In the refrigerator 11, an RFID tag reader / writer 18 that reads an RFID tag 17 mounted on food stored therein, and a purchased food management database (hereinafter referred to as “purchased food management DB”) for managing the read food. ) Stored as a storage means, a display unit 20 for displaying information on food, and an IC chip reader / writer 21 for writing data on food in the mobile storage device 12. .

  The mobile storage device 12 is specifically an IC card 23 on which an IC chip 22 is mounted. The IC chip 22 stores data related to the food to be purchased selected in the refrigerator 11. The IC card 23 is assumed to be used for a point service or the like as a member card of the store 14.

  The server 13 has a food management database (hereinafter also referred to as “food management DB”) in which information related to food sold at the store 14 is managed, and a recipe management database (hereinafter referred to as “food management DB”) in which information related to recipes is stored and managed. , Which is also referred to as “recipe management DB”). From the server 13, various information regarding food, information regarding recipes, and the like are transmitted to the refrigerator 11 via the Internet 16.

  The cart 15 reads data relating to food from the RFID tag reader / writer 25 for reading the RFID tag 17 attached to food packaging and the like, and the mobile storage device 12 in which data relating to food scheduled to be purchased is stored. IC chip reader / writer 26 and a cart display unit 27 for displaying the sales location of the food to be purchased.

  Next, a data configuration diagram of the purchased food management DB stored in the purchased food management unit 19 of the refrigerator 11 will be described. As shown in FIG. 2, the purchased food management DB includes a key 31, a food ID 32, a food name 33, an expiration date 34 expressed in the YYYYMMDD format, and the number of foods 35.

  Here, the key 31 has a data structure in which the food ID 32 and the expiration date 34 are linked. For example, when there is a food with the same food name 33 and a different expiration date 34, when the information regarding the recipe is selected, a product with a near expiration date is preferentially searched. Therefore, the purchased food management DB needs to be managed as separate data. Therefore, the key 31 has a data structure in which the food ID 32 and the expiration date 34 are linked.

Next, the data structure of the RFID tag attached to the packaging or the like of food sold at the store 14 will be described. As shown in FIG. 3, information about the food ID 32, the food name 33, the expiration date 34, and the storage flag 36 is stored in the RFID tag 17 mounted on the food.
Next, the data structure of the RFID tag attached to the package of the purchased food will be described. As shown in FIG. 4, the RFID tag 17 stores information regarding the food ID 32, the food name 33, the expiration date 34, and the storage flag 36.

  The difference between the information stored in the RFID tag 17 shown in FIG. 3 and the information stored in the RFID tag 17 shown in FIG. 4 is that the value of the storage flag 36 depends on whether or not food is stored in the refrigerator 11. It is different. For example, before the food is stored in the refrigerator 11, that is, when the food is sold at the store 14, the value of the storage flag 36 is 0 (unstored). When the food is stored in the refrigerator 11, the value of the storage flag 36 is updated to 1 (memory) by the RFID tag reader / writer 18 provided in the refrigerator 11. Further, when food is taken out from the refrigerator 11, the storage flag 36 is updated to 0 by the RFID tag reader / writer 18.

  Next, the configuration of data stored in the IC card 23 that is the mobile storage device 12 will be described. As shown in FIG. 5, the IC card 23 stores information related to the food ID 32, the food name 33, and the number of products 35. For example, when there is a food necessary for the recipe, the food ID 32, the food name 33, and the number 35 of the food to be purchased are stored in the IC chip 22 of the IC card 23.

  Next, the configuration of data stored in the food management DB in the server 13 will be described. As shown in FIG. 6, the food management DB stores information on food ID 32, food name 33, price 37, and special sale flag 38. For example, when domestic Wagyu beef is sold at a certain store 14, the special sale flag 38 is set to 1. With this special sale flag 38, when information about recipes in the recipe management DB is arranged, information on recipes that have many special sale flags set to 1 is arranged higher.

  Next, the configuration of data stored in the recipe management DB of the server 13 will be described. As shown in FIG. 7, the recipe management DB stores information on food ID 32, recipe 39, used food ID 40-1 to used food ID 40-n. For example, when the food stored in the refrigerator 11 is tofu, all recipe information corresponding to the tofu food ID 32 is acquired from the recipe management DB. And foodstuffs other than tofu required by each recipe are set to use food ID40-1-use food ID40-n.

Next, a method for performing food management using the food purchase management support system configured as described above will be described. Note that the following processing is executed under the control of a CPU (not shown) serving both as an acquisition unit and a determination unit based on a predetermined program or the like.
First, the outline | summary of the memory | storage of the information regarding the foodstuff to the refrigerator 11 and taking out is demonstrated. As shown in FIG. 8, it is first determined whether or not the RFID tag 17 attached to the food packaging or the like has approached the RFID tag reader / writer 18 (step S801).

  When it is determined that the RFID tag 17 is close to the RFID tag reader / writer 18, the information of the RFID tag 17 is read by the RFID tag reader / writer 18, and the food ID 32, the food name 33, the expiration date 34, and the storage shown in FIG. Each information regarding the flag 36 is acquired (step S802). Next, the key 31 in the purchased food management DB is created based on the food ID 32 and the expiration date 34 (step S803).

  Next, the value of the storage flag 36 in the RFID tag 17 is determined (step S804). When the value of the storage flag 36 is 0, food is not stored in the refrigerator 11. On the other hand, when the value of the storage flag 36 is 1, food is stored in the refrigerator 11. Therefore, when the RFID tag 17 attached to the food packaging or the like passes through the RFID tag reader / writer 18 provided in the refrigerator 11, if the value of the storage flag 36 is 0, it is stored in the refrigerator 11 from now on. The value of the storage flag 36 is changed to 1 when stored in the refrigerator 11 (step S805).

  Next, it is determined whether or not the key 31 created by connecting the food ID 32 and the expiration date 34 is the same as the key 31 of the purchased food management DB (step S806). When the same thing as the key 31 of purchased food management DB does not exist, it is in the state where the same food and the same expiration date do not exist in the refrigerator 11, and data is newly registered into the purchased food management DB ( Step S807). On the other hand, when the same thing as the key 31 of purchase food management DB exists, it is in the state that the same food and the same expiration date already exist, and it has already registered with the same key 31 in purchase food management DB. Therefore, the number of foods 35 corresponding to the same key 31 is incremented (step S808).

  If the value of the storage flag 36 is 1 in step S804, the food is already stored in the refrigerator 11. Therefore, when food is taken out from the refrigerator 11, the storage flag 36 is changed to 0 (step S809). Next, determination is made regarding the number of foods 35 for which the key 31 created by connecting the food ID 32 and the expiration date 34 is the same as the key 31 of the purchased food management DB (step S810).

  When the number of foods 35 is one, there is no other food in the refrigerator 11 that has the same food and the expiration date 34. At this time, when the food is taken out from the refrigerator 11, since the same food with the same expiration date 34 does not exist in the refrigerator 11, the data is deleted from the purchased food management DB (step S 811). When the number of foods 35 is two or more, the same food and the same expiration date 34 still exist. At this time, when food is taken out from the refrigerator 11, since the same food and the same expiration date 34 still exist in the refrigerator 11, the number of foods corresponding to the same key 31 in the purchased food management DB 35 is decremented (step S812).

Next, display processing when a recipe is displayed on the display unit 20 of the refrigerator will be described.
As shown in FIG. 9, first, as food stored in the refrigerator 11, all food data is acquired from the purchased food management DB in the order of near expiration date (step S901). Next, the acquired food data is displayed on the display unit 20 of the refrigerator 11 (step S902). The display unit 20 displays a recipe button for each food item, and determines whether or not the recipe button has been pressed (step S903). When it is determined that the recipe button has been pressed, an acquisition request for information regarding the recipe corresponding to the selected food ID 32 is transmitted from the refrigerator 11 to the server 13 connected via the Internet 16 (step S904).

  The server 13 determines whether or not the recipe information corresponding to the transmitted food ID 32 exists in the recipe management DB (step S905). And when data exist in recipe management DB, while using used food ID32, the information on the food corresponding to used food ID32 is acquired from food management DB. Next, the total amount of food used in the recipe is calculated using the food price 37 (step S906).

  On the other hand, when the recipe information corresponding to the food ID 32 transmitted from the refrigerator 11 does not exist in the recipe management DB, there are many used foods whose value of the sale flag 38 in the food management DB corresponding to the used food is 1. Recipe data is arranged in the order of the order (step S907). 1 is set in the special sale flag 38 of the food handled as special sale in the store 14. Next, from the server 13 to the refrigerator 11, the food ID 32, the food name 33, the price 37, the recipe 39, the food ID 32 of the used food, the food name 33 of the used food, the price 37 of the used food, and the special sale flag 38. Each data of the total amount is transmitted.

  Next, as shown in FIG. 10, in the refrigerator 11, it is determined whether or not the used food IDs 32 transmitted from the server 13 are present in the purchased food management DB in a necessary number (step S909). When the necessary number of the same food IDs 32 exists in the purchased food management DB, the price 37 of the used food with the used food ID 32 is subtracted from the total amount acquired from the server 13 (step S910). This is because when the total amount of the recipe is displayed on the display unit 20 of the refrigerator 11, the food already stored in the refrigerator 11 does not need to be purchased, so the price of the food needs to be deducted from the total amount. Because there is.

  Next, when the same food ID 32 exists in the purchased food management DB, the used food ID 32 transmitted from the server 13 is excluded from the used food of the recipe. This is because when the food used for the recipe is displayed on the display unit 20, it is not necessary to purchase the food already stored in the refrigerator 11, so that the food is not displayed on the display unit 20. .

  On the other hand, if it is determined in step S909 that the required number of the same food IDs 32 does not exist in the purchased food management DB, the purchased food management DB is searched with the used food IDs 32 that are not targeted, and the expiration date is expired. 34 is acquired (step S912). Next, the number of used foods that are not excluded is small, and the expiration dates 34 of the used foods that are not excluded are arranged in order from the expiration date (step S913). This is the display order when the recipe is displayed on the display unit 20. Next, the total amount of the recipe, the food used, and the recipe is displayed on the display unit 20 (step S914).

Next, processing when food purchased in the refrigerator 11 is stored in the IC card 23 will be described.
As shown in FIG. 11, first, when the total amount of recipe, used food, and recipe is displayed on the display unit 20 of the refrigerator 11, it is determined whether or not the recipe confirmation button displayed on the display unit 20 has been pressed. (Step S111). When it is determined that the recipe confirmation button has been pressed, the purchased food name 33 and the purchased food price 37 are displayed on the display unit 20 (step S112). Next, it is determined whether or not the purchase button displayed on the display unit 20 has been pressed (step S113).

  Next, in order to store the information related to the purchased food in the mobile storage device 12, a request for deduction of the IC chip 22 is displayed on the display unit 20 (step S114). Next, it is determined whether or not the mobile storage device 12 is trapped by the IC chip reader / writer 21 (step S115). If it is determined that the mobile storage device 12 has been deceived by the IC chip reader / writer 11, information regarding the food ID 32, the food name 33, and the number 35 of the purchased food is written (step S116). After the writing is completed, a writing completion message is displayed on the display unit 20 (step S117).

Next, a processing method when purchased food is stored in the cart 15 in the cart 15 provided in the store 14 will be described.
As shown in FIG. 12, first, a trick request message of the mobile storage device 12 is displayed on the cart display unit 27 of the cart 15 (step S121). Next, it is determined whether or not the mobile storage device 12 has been trapped by the IC chip reader / writer 26 (step S122). When it is determined that the mobile storage device 12 has been deceived, the food ID 32, the food name 33, and the number 35 are read from the IC chip 22 (step S123). For example, if “0400000701 (chicken (200 g))” and “0600000012 (Sanuki udon)” exist in the food ID 32, the two pieces of information are collectively read into the IC chip 22 (hereinafter referred to as purchase) Food list).

  Next, in order to process the read purchased food information one by one, it is determined whether or not the purchased food information read from the IC chip 22 exists (step S124). If there is information on the purchased food read from the IC chip, the food name 33 of the purchased food, the number 35 to be purchased, and the sales position of the purchased food are displayed on the cart display unit 27 of the cart 15 (step S125). . The cart display unit 27 is in a waiting state until the next event occurs. The event includes a case where purchased food is stored in the cart 15, a cancel button is pressed, a next button is pressed, and the like.

  The event when the purchased food is stored in the cart 15 occurs when the consumer goes to the food sales position displayed on the cart display unit 27 and places the purchased food in the cart 15. The processing for deleting the list of purchased foods is determined based on the number of purchased foods. If there are two or more purchased foods, the number 35 of the purchased food list is decreased by one as the purchased food is put into the cart 15 one by one. On the other hand, when there is one purchased food in the purchased food list, the data of the purchased food is deleted from the purchased food list.

The event when the cancel button is pressed in the cart 15 occurs when the purchase of the food that was planned to be purchased by the consumer is stopped. Therefore, the canceled purchased food is deleted from the purchased food list.
The event when the next button is pressed occurs when the consumer holds the food displayed on the cart display unit 27 and the next food is referred to. Therefore, in the event of the next button, the purchased food is not deleted from the purchased food list.
When the above processing is completed for all food lists, a purchase food completion message is displayed on the cart display unit 27 (step S126).

Next, the example of a screen which shows the food list of the refrigerator 11 in the display process (step S902 of FIG. 9) performed in a refrigerator is demonstrated.
As shown in FIG. 13, the screen showing the food list of the refrigerator includes a food name 51, a shelf life 52, a number 53, and a recipe button 54. When the recipe button 54 is pressed, a transition is made to a recipe screen.

  Next, the screen which shows the recipe displayed on the display part 20 of the refrigerator 11 is demonstrated. As shown in FIG. 14, on the recipe display screen, the recipe name 55, the selected food name 56, the total amount 57 of the recipe, the used food name 58, the number 59, the recipe 60, the recipe confirmation button 61, the next button 62, the previous button 62, It consists of a button 63. The selected food name 56 corresponds to the food name 51 in the refrigerator food list shown in FIG. As for the used food name 58, only the food items that are not enough in the refrigerator 11 when the recipe is made are displayed. The total amount 57 displays the total amount of food that must be purchased. When the recipe confirmation button 61 is pressed, the screen shifts to a purchase food selection screen. When the next button 62 and the previous button 63 are pressed, the next recipe or the previous recipe is displayed.

  Next, a screen when purchased food is selected in the refrigerator 11 will be described. As shown in FIG. 15, on the screen for selecting the food to be purchased in the refrigerator, the selected recipe name 64, the purchased food name 65, the number 66, the price 67, the selection check box 68, the collective selection button 69, the purchase button 70, It consists of a cancel button 71. The selected recipe name 64 corresponds to the recipe name 55 in FIG. In the purchased food name 65, the number 66, and the price 67, each information of the food to be purchased is displayed.

  The check box 68 is used to select whether or not the food is to be purchased. When the check box 68 is checked, the check box 68 becomes data to be written to the mobile storage device 12. When the collective selection button 69 is pressed, the check boxes 68 of all the purchased food items displayed are checked. When the purchase button 70 is pressed, the purchased food is determined and written into the mobile storage device 12. When the cancel button 71 is pressed, the screen shifts to a screen showing a recipe in the refrigerator 11 of FIG.
