(Embodiment 1)
FIG. 1 is a schematic diagram showing a configuration example of a food management system. In the present embodiment, it is a food management system that manages the freshness of food in the distribution process from the production area to the consumer's house, and the food in the distribution process (first distribution process) from the production area to the delivery base. Food management in which the freshness is managed by the packing tag 3 (first reading medium) and the freshness of food in the distribution process (second distribution process) after shipping from the delivery base is managed by the individual tag 4 (second reading medium). The system will be described. The freshness management system includes a food management device 1, terminals 2, 2, 2, .... Each device is communicated and connected via a network such as the Internet.

Although the description mainly assumes fresh foods in the present embodiment, the foods referred to in this specification are not limited to fresh foods, and may include aged foods, processed foods, and the like. In this system, it is sufficient that the freshness of food can be controlled based on the packing tag 3 and the individual tag 4, and the food to be managed is not particularly limited.

The food management device 1 is an information processing device capable of transmitting and receiving various types of information processing and information, such as a server device and a personal computer. In the present embodiment, the food management device 1 is assumed to be a server device, and is read as a server 1 for the sake of brevity.

Collect and store in the database. Then, the server 1 estimates the freshness information indicating the expiration date, the best time to eat, the expiration date, etc. of the food based on the accumulated data.

The terminal 2 is a client terminal that communicates with the server 1, for example, a smartphone, a personal computer, a tablet terminal, or the like. The user who operates the terminal 2 is, for example, a consumer who finally consumes the food, or a clerk of a store such as a retail store that sells the food to the consumer. In the following description, the terminal 2 operated by the consumer is referred to as the consumer terminal 2a, and the terminal 2 operated by the store clerk is referred to as the store terminal 2b.

The packing tag 3 is a cardboard box or the like used when shipping food from a production area to a delivery base, and is a wireless tag attached to a packing body for storing a plurality of foods. For example, the packing tag 3 is an IC tag related to RFID, and transmits identification information (hereinafter, referred to as “packing ID”) indicating a food group stored in the packing body. Further, the packing tag 3 has a sensor (for example, a temperature sensor) that detects environmental data around the packing body, and transmits the environmental data detected by the sensor together with the packing ID. The wireless communication standard of the packing tag 3 is not particularly limited, and may be a wireless tag conforming to a communication standard such as Bluetooth (registered trademark) or Wi-fi (registered trademark).

The individual tag 4 is a wireless tag attached to each food item stored in the package, and is an IC tag that transmits identification information (hereinafter, referred to as "individual ID") of each food item. The individual tag 4 may be an active tag having a power supply inside, or a passive tag having no power supply. Unlike the packing tag 3, the individual tag 4 is not provided with a sensor or the like for detecting environmental data, and has a simple configuration in which only an individual ID is transmitted. The packing tag 3 and the individual tag 4 are supplied by a predetermined packaging company. After the individual tag 4 is attached to each food under the production area or the packaging company, a predetermined number of food groups are stored in the packing body, the packing tag 3 is attached, and the food is shipped to the delivery base. ..

When the food group is stored in the packing body and transported to the delivery base, the packing body such as a cardboard box and / or the individual food is provided by the film 7 (packaging material) supplied from a predetermined film supplier. It is shipped after being packaged. The film 7 is an organic medium film used for the purpose of maintaining the freshness of food in the distribution process, and is, for example, a stretch film for food. As will be described later, the server 1 estimates the freshness information according to the type of the film 7 and the like as well as the data obtained by reading the packing tag 3 and the individual tag 4.

In the present embodiment, the reader 5 that reads the packing tag 3 and / or the individual tag 4 temporarily collects the foods shipped from each production area and delivers them to each place, or the home of the consumer who purchased the foods. Etc., which are dispersed in the food distribution process (see FIGS. 5 and 6). The server 1 collects data obtained by each reader 5 reading the packing tag 3 and the individual tag 4. Specifically, the server 1 collects food data (first data) transported from the production area to the delivery base based on the packing tag 3 (and the individual tag 4). Further, the server 1 collects data (second data) of foods distributed from the delivery base to the consumer via the store or foods directly sent from the delivery base to the consumer based on the individual tag 4. The server 1 stores the data read by each reader 5 in a database, estimates the freshness information such as the expiration date and the time when the food is eaten, and outputs the data to the terminal 2 such as the consumer terminal 2a and the store terminal 2b. ..

FIG. 4 is an explanatory diagram showing an example of record layouts of the individual DB 141, the packing DB 142, the transport vehicle DB 143, the base DB 144, and the user DB 145.
The individual DB 141 includes an individual ID column, a food name column, a film column, a food information column, and a received data string. The individual ID column stores an ID for identifying the individual tag 4 assigned to each food item. The food name column, film column, food information column, and received data string are associated with individual IDs, and the name of the food to which the individual tag 4 is attached, the type of film 7 (packaging material) for packaging the food, and the food. It stores food information indicating the production area, producer, production conditions, etc., and data received from the reader 5 that has read the individual tag 4. In the received data string, for example, the ID of the reader device that is the reading source and the storage temperature of the food are stored in association with the reading date and time of the individual tag 4.

The packing DB 142 includes a packing ID column, a packed food column, a film column, and a received data string. The packing ID column stores an ID for identifying the packing tag 3 assigned to each packing, which is a transportation unit of food. The packaged food column, the film column, and the received data string are associated with the packaging ID, and the ID of the individual tag 4 attached to the packaged food, the type of film 7 (packaging material) for packaging the package, and so on. And the data received from the reader 5 that has read the packing tag 3 is stored. In the received data string, for example, the ID of the reader device that is the reading source and the storage temperature of the food are stored in association with the reading date and time of the packing tag 3.

The transport vehicle DB 143 includes a transport vehicle ID column, a reader ID column, and an air conditioning information column. The transport vehicle ID column stores an ID for identifying the transport vehicle. The reader ID column and the air-conditioning information column correspond to the transport vehicle ID, respectively, with the ID of the reader 5 installed on the loading platform (space) for loading food in the transport vehicle, and the air conditioning information installed on the loading platform. I remember.

The base DB 144 includes a base ID column, a base name column, a position column, a reader ID column, a receiving column, and a shipping column. The base ID column stores an ID for identifying each delivery base. The base name column, the location column, the reader ID column, the receiving column, and the shipping column are associated with the base ID, respectively, and the name of the delivery base, the location information, the ID of the reader device in the delivery base, the food receipt history, and the food receipt history. I remember the shipping history. In the receiving line, for example, the ID of the packing tag 3 attached to the packing body of the arrived food is stored in association with the arrival date and time when the food (packing body) arrives at the delivery base. In the shipping column, for example, the ID of the individual tag 4 is displayed when the food is shipped in individual food units, and the ID of the packing tag 3 is displayed when the food is shipped in packing units, in association with the shipping date and time when the food was shipped from the delivery base. It is remembered.

The position column, the reader ID column, and the order history column are associated with the user ID, respectively, to indicate the location information of the user's home, the ID of the reader device installed in the refrigerator at the user's home, and the food from the user. The order history is memorized. In the order history column, for example, the ID of the individual tag 4 attached to the ordered food and the selling price of the food are stored in association with the order date and time of the food.

FIG. 5 is an explanatory diagram of freshness management processing in the distribution process. Based on FIG. 5, a process of managing the freshness of food in the distribution process from the production area to the delivery base based on the packing tag 3 (and the individual tag 4) will be described.

As described above, when food is shipped from the production area, the packing tag 3 is attached to a predetermined packing unit, and the individual tag 4 is attached to each food before shipping. The packing tag 3 is a wireless tag having a sensor for detecting environmental data around the packing body, and transmits the packing ID and environmental data to a reader 5 located within a predetermined range by short-range wireless communication. Unlike the packing tag 3, the individual tag 4 is a wireless tag having a simple configuration and does not have a sensor, and only the individual ID is transmitted to the reader 5.

For example, in the production area, packing tags 3 and individual tags 4 supplied by a predetermined packaging company are prepared, attached to the packing body and individual foods, and then shipped to the delivery base by a transport vehicle such as a truck. .. The packing tag 3 and the individual tag 4 do not necessarily have to be attached at the place of production. For example, the packaging company may attach the packing tag 3 and the individual tag 4 and ship the product to the delivery base. Further, the means of transportation to the delivery base is not limited to a vehicle (transport vehicle), and may be, for example, a ship, an aircraft, or the like.

Further, in the production area, the film 7 supplied from a predetermined film supplier is used to wrap a packing body such as a cardboard box and / or individual foods and then shipped to the delivery base. As described above, the film 7 is a stretch film for foods and the like, and is a packaging material used for the purpose of maintaining the freshness of foods. As will be described later, the film supplier supplies various films 7 having different materials and structures depending on the use (food to be packaged, etc.). The producer receives the supply of the type of film 7 according to the food to be shipped from the film supplier, wraps the package and individual foods, and then ships the film 7 to the delivery base.

For example, when food is shipped from the production area, the server 1 accepts registration of food information regarding the food to be shipped from the producer. The food information includes, for example, information related to the food itself such as the food name, producer, and production area, the individual ID of the individual tag 4 given to each food, the packing ID of the packing tag 3 given to the packing body, and the packing. Includes information (type) and the like of the film 7 that wraps the body and individual foods. The server 1 stores the acquired food information in each database.

In the present embodiment, in the distribution process, a transport vehicle (moving body) for transporting food from the production area to the delivery base and a leader 5 are provided at the delivery base. The location where the reader 5 is installed in the distribution process is an example, and the server 1 may be able to acquire the data obtained by the reader 5 reading the packing tag 3 in the distribution process. In the following description, for convenience, the reader 5 in the transport vehicle is represented by reference numeral 5a, and the reader 5 at the delivery base is represented by reference numeral 5b. The server 1 acquires the read data from the readers 5a and 5b that read the packing tag 3 (and the individual tag 4), and stores the read data in each database.

The reader 5a in the transport vehicle is a stationary reader device installed on the loading platform (space) of the transport vehicle for loading food. The readers 5a installed on the loading platform of the transport vehicle may be single or plural.

The reader 5a reads the packing tag 3 of each packing body sequentially or periodically at the time of transportation, and transfers the read data to the server 1. The data read by the reader 5a includes a packing ID for identifying the packed food group, environmental data detected by the sensor of the packing tag 3 at the time of reading, and the like. The environmental data is, for example, the temperature detected by a temperature sensor. The server 1 acquires the reader ID of the reader 5a, which is the reading source of the packing tag 3, in addition to the packing ID, environmental data, and the like from the reader 5a. Then, the server 1 stores the environmental data detected by the sensor of the packing tag 3 in the packing DB 142 in association with the packing ID, the reading time, the reader ID, and the like.

The environmental data detected by the sensor of the packing tag 3 is not limited to the temperature, and for example, the sensor may be used as a humidity sensor to detect the humidity around the packing body. Further, the sensor may be used as a gas sensor to detect the composition of gas generated from food (for example, carbon dioxide concentration). Alternatively, the packing tag 3 may be provided with each sensor so that it can detect a plurality of environmental data such as temperature, humidity, and gas composition. As described above, the environmental data detected by the sensor of the packing tag 3 may be any data that can estimate the storage state of food, and the content thereof is not particularly limited.

Further, the server 1 acquires environmental data of food from the transport vehicle and stores it in the packing DB 142, and also generates control information for controlling the air conditioner in the loading platform based on the acquired environmental data of the transport vehicle. Output to.

The presence or absence of an air conditioner in the loading platform is not particularly limited, but for example, when transporting fresh food, a transport vehicle equipped with an air conditioner for adjusting the temperature in the loading platform may be used. However, depending on the temperature setting of the air conditioner, the angle setting of the outlet, the setting of the air volume, etc., the temperature distribution in the loading platform may be biased, and it is appropriate among the many packing bodies (cardboard boxes, etc.) loaded in the loading platform. Some packaging may not be stored at a high temperature.

Therefore, the server 1 generates control information for controlling the air conditioner based on the environmental data acquired from the packing tag 3 and outputs it to the transport vehicle. The control information is information for controlling, for example, the temperature, the angle of the outlet, the air volume, and the like. The control information may be information (command) for the server 1 to remotely control the air conditioner, or may be simply a notification for instructing the driver or the like of the transport vehicle to set the air conditioner.

For example, the server 1 estimates the temperature distribution in the loading platform and optimizes the temperature distribution based on the environmental data acquired from the packing tags 3, 3, 3, ... Corresponding to each of the plurality of packing bodies loaded in the loading platform. Generate control information for. For example, when the server 1 acquires the read data of each packing tag 3 from the reader 5a, the server 1 acquires the communication strength between the reader 5a and the packing tag 3 as a part of the reading data, and each packing tag is obtained from the acquired communication strength. By estimating the position (distance from the reader 5a) in the loading platform of 3, the temperature distribution in the loading platform is estimated.

After arriving at the delivery base, the freshness management of food at the delivery base is performed by the reader 5b of the delivery base reading the packing tag 3 (and the individual tag 4). The reader 5b is a short-range wireless communication device similar to the reader 5a of a transport vehicle, and may be a device of various modes such as a stationary type, a handy type, and a gate type. For example, at a delivery base, freshness management is performed by combining the above-mentioned readers 5b, 5b, 5b ...

Like the reader 5a, the reader 5b reads the packing ID, environmental data, etc. from the packing tag 3 and transfers the packing ID, the reader ID of the reader 5b, which is the reading source, to the server 1 via the base terminal 6. The server 1 stores the environmental data in the packing DB 142 in association with the packing ID, the reading time, the reader ID, and the like. As a result, the server 1 stores the data of each food item arriving from the production area and temporarily stored at the delivery base in the packing DB 142.

In the above description, it has been explained that the reader 5b reads the packing tag 3 and transfers the read data to the server 1, but the present embodiment is not limited to this, and the individual tag 4 is also read and the data is transferred. You may try to do it. That is, the server 1 may be able to acquire at least the data read from the packing tag 3, and the individual tags 4 may be combined to manage the freshness in the distribution process.

The server 1 acquires the data read from the packing tag 3 and determines whether or not the food has arrived at the delivery base based on the acquired data. For example, the server 1 may determine whether or not it has arrived at the delivery base based on the reader ID transmitted together with the packing ID and the like. When it is determined that the film 7 has arrived at the delivery base, the server 1 determines that the use of the film 7 in which the package is packaged has been completed, and outputs a new film 7 order request (order information) to the film supplier. To do. The order request includes, for example, information indicating the type of film 7 used. When the order request is obtained from the server 1, the film supplier newly ships (supplies) the film 7 of the same type to the production area. As a result, the film 7 can be smoothly supplied.

In the above description, it has been explained that the order request for the film 7 in which the package is packaged is output based on the data (first data) read from the package tag 3, but as will be described later, this implementation In the form, the server 1 also manages food after shipping from the delivery base based on the individual tag 4. Therefore, the server 1 not only outputs an order request for the film 7 for the packing body based on the data read from the packing tag 3, but also outputs each individual tag 4 based on the data (second data) obtained by reading the individual tag 4. It may be determined whether or not the use of the food film 7 is completed, and an order request for each food film 7 may be output. That is, the server 1 determines whether or not the use of the film 7 of the package or individual food is completed based on the data from the packing tag 3 (first data) or the data from the individual tag 4 (second data). It suffices if the order request can be output when the judgment is made and the use is completed.

FIG. 6 is an explanatory diagram regarding processing after shipping food from the delivery base. FIG. 6 conceptually illustrates a process of managing the freshness of food in the distribution process after shipping from the delivery base based on the individual tag 4.

Before explaining the freshness management process of food after shipping from the delivery base, the process of outputting the collection request (collection information) of the packing tag 3 to the packaging company will be described. For example, the server 1 may output a collection request for the packing tag 3 to a packaging company when food is shipped from the delivery base to a store, a consumer's house, or the like. Specifically, the server 1 determines whether or not the food has been shipped from the delivery base based on the data obtained by reading the packing tag 3 or the individual tag 4 by the reader 5b of the delivery base. At the delivery base, the tag is generally read by the reader 5b when the package (food) is shipped. For example, the server 1 receives a shipping notification from the base terminal 6 when the reading is performed, and determines whether or not the food has been shipped.

When it is determined that the food has been shipped, the server 1 outputs a collection request for the packing tag 3 to the packaging company. The packaging company that received the collection request collects it from the packing tag 3 from the delivery base, supplies it to the producer, and reuses it. As a result, the individual tag 4 that transmits only the individual ID is disposable, while the relatively expensive packing tag 3 having the sensor can be reused, and both can be used appropriately.

In the above, when the use of the packing tag 3 is completed, the collection request is automatically notified to the packaging company. For example, the server 1 has the packing tag 3 that has been used, that is, the packing tag to be collected. 3 may only be notified to the employees of the delivery base. That is, the server 1 only needs to be able to output collection information indicating the existence of the packing tag 3 to be collected, and the configuration of requesting the collection of the packing tag 3 to the outside is not essential.

Next, the freshness management process after food shipment will be explained. As described above, the server 1 manages the freshness of the food after shipping from the delivery base based on the individual tag 4. For example, a reader 5 is provided in each of a store where food is distributed, a consumer's house, etc., and the server 1 indicates an individual ID obtained by reading the individual tag 4 from each reader 5 and a storage status at the time of reading. Various data including stored information are acquired and stored in the individual DB 141. In the following description, for convenience, the reader 5 of the store is represented by the reference numeral 5c, and the reader 5 of the consumer's home is represented by the reference numeral 5d.

It should be noted that the stores and the homes of consumers are all examples of the reading locations of the individual tags 4, and the server 1 can acquire the data of the foods shipped from the delivery base from the reader 5 that has read the individual tags 4. It should be.

The store reader 5c is a short-range wireless communication device installed in a warehouse where food is stored in the store, a refrigerator, or a display shelf for displaying food (goods), and is sequentially or periodically from the individual tag 4. The individual ID is read and output to the store terminal 2b. Then, the store terminal 2b acquires the temperature of the storage location at the time when the individual tag 4 is read together with the individual ID by a predetermined means, and transfers the temperature to the server 1. For example, in a store, a temperature sensor is installed near the reader 5c, and the store terminal 2b transfers the storage temperature acquired from the temperature sensor to the server 1. The server 1 acquires the reader ID of the reader 5c in addition to the individual ID and the storage temperature from the store terminal 2b, associates them with the reading time, and stores them in the individual DB 141.

The reader 5d in the consumer's home is a wireless communication device similar to the reader 5c and the like, and is provided in, for example, the refrigerator 8 installed in the consumer's home. The refrigerator 8 is connected to an external network via, for example, a router device (not shown), and can communicate with the server 1. The refrigerator 8 reads the individual ID from the individual tag 4 of each food stored in the refrigerator by the reader 5d. Then, the refrigerator 8 transmits the individual ID, the temperature inside the refrigerator at the time when the individual tag 4 is read, the reader ID of the reader 5d, and the like to the server 1. The server 1 stores the storage temperature in the individual DB 141 in association with the individual ID, the reading time, the reader ID, and the like.

The server 1 is stored in the consumer's house or store based on the read data of the individual tag 4 stored in the individual DB 141 at each time point and the read data stored in the packing DB 142 at each time point in the distribution process. The freshness information of the food is estimated and notified to the consumer terminal 2a and the store terminal 2b, respectively. For example, when the server 1 receives an output request for freshness information from each terminal 2, the server 1 refers to each database, identifies each food product stored in the consumer's house or store, which is the request source, and identifies each food product. Estimate the freshness information of food and output it to the terminal 2.

For example, the server 1 is stored in the consumer's home or store by specifying the individual ID of each food item associated with the reader IDs of the readers 5d and 5c of the consumer's home or store, which is the request source, from the individual DB 141. Identify each food (individual) that is present. For example, when the server 1 receives the output request from the terminal 2, the readers 5c and 5d may scan the food again. The server 1 is the read data at each time point stored in the individual DB 141 for each of the specified foods, the environmental data detected by the sensor of the packing tag 3, and the environmental data stored in the packing DB 142 at each time point. It is the read data, and the storage temperature of the food at the time of reading the individual tag 4 is read. The server 1 estimates the expiration date of each food, the best time to eat, and the like as freshness information from the data at each time point read from the individual DB 141 and the packing DB 142.

For example, the server 1 first refers to the packing DB 142 and estimates the freshness information of the food in the distribution process from the data obtained by reading the packing tag 3 in the distribution process. For example, the server 1 has the elapsed time required in the distribution process, such as the transportation time from the production area to the delivery base, the storage time at the delivery base, and the temperature, humidity, etc. detected by the sensor of the packing tag 3 at each time point. Based on the time-series transition of environmental data, the freshness information of food at the time when each food is taken out from the package at the distribution base and shipped to stores, consumer homes, etc. is estimated.

Alternatively, the sensor of the packing tag 3 may be used as a gas sensor, and the freshness information of the food may be estimated from the composition of the gas generated from the food. For example, the server 1 estimates the freshness information at the time of being taken out from the package by comparing the concentration of a predetermined gas component (for example, carbon dioxide) last detected by the gas sensor with a predetermined threshold value. In this case, the server 1 does not need to indirectly estimate from the time series transition such as temperature and humidity, and can directly and accurately estimate the freshness information.

Next, the server 1 refers to the individual DB 141, and at present, based on the freshness information in the distribution process estimated above and the data obtained by reading the individual tag 4 in the distribution process after shipping from the distribution base. Estimate the freshness information of foods in Japan. For example, the server 1 refers to the individual DB 141 to determine the elapsed time after being shipped from the delivery base, the time-series transition of the storage temperature of food in the consumer's house, the store, and the like. The server 1 estimates the freshness information of the food at the present time from the elapsed time after the shipment, the time-series transition of the storage temperature, etc., in addition to the freshness information immediately after the shipment from the distribution base.

Further, for example, the server 1 may refer to the pre-registered food information when estimating the freshness information. For example, the server 1 uses information on production conditions when food is produced, in addition to basic information such as the type of food (food name). The production conditions are, for example, the type of pesticide used. When the food is shipped, the server 1 accepts registration of information on the production conditions together with the food name, production area, etc., and estimates the freshness information of the food according to the type of food and the production conditions. This makes it possible to estimate accurate freshness information in light of the attributes of individual foods.

Further, the server 1 not only provides information on the food itself such as the type of food, production conditions, etc., but also the type of the film 7 that wraps the package in the distribution process, and / or the type of the film 7 of each food. The freshness information may be estimated according to the above. As described above, the type of film 7 differs depending on its use, and the freshness of food varies depending on the type. Therefore, the server 1 can estimate more accurate freshness information by referring to the type of the film 7.

Server 1 estimates freshness information for each food item stored in the consumer's home or store that is the requester. For example, in the case of a consumer's house, the server 1 provides freshness information for all the foods stored in the refrigerator 8 of the consumer's house and to which the individual tag 4 according to the present embodiment is attached. presume. The server 1 outputs the estimated freshness information to the terminal 2 and displays it.

7A and 7B are explanatory views showing an example of the display screen of the terminal 2. When the freshness information is acquired from the server 1, the terminal 2 displays the food list screen illustrated in FIG. 7A. The food list screen is a screen for displaying a list of foods stored in a consumer's house or a store, and is a screen for displaying freshness information of each food in a list.

As shown in FIG. 7A, the terminal 2 displays freshness information such as the expiration date and the best time to eat in association with the food name of each food. In addition, the terminal 2 displays the food that reaches the deadline within the predetermined period in a form different from that of other foods by color coding or the like, and alerts the user (consumer or clerk). As a result, the user can easily grasp the food to be consumed immediately.

In the above, when the server 1 presents the freshness information to the consumer, the freshness information is output to the terminal 2 (consumer terminal 2a) such as a smartphone. For example, the freshness is output to the refrigerator 8 in the consumer's house. Information may be output and displayed on a predetermined display. As a result, the consumer can confirm the expiration date, the best time to eat, and the like without browsing the terminal 2, and the convenience can be improved.

Further, the terminal 2 receives an additional ordering request for food from the food list screen of FIG. 7A, and requests the server 1 to deliver the ordered food from the delivery base to the consumer's house or the store.

For example, the terminal 2 accepts a selection input for selecting one of the foods on the list screen, and transitions to the ordering screen shown in FIG. 7B. The ordering screen is a reception screen for accepting an ordering request for the selected food. For example, the terminal 2 displays the food name, selling price, and the like of the food to be ordered on the ordering screen, and also displays an input field for inputting the quantity of the food to be ordered, the desired delivery time, and the like. On the ordering screen, the terminal 2 receives the input of the order quantity, the desired delivery time, and the like and transmits the input to the server 1, and requests that the input quantity of food be delivered at the desired delivery time.

When the terminal 2 accepts the selection input of any food from the list screen, the server 1 is a delivery base that stores the selected food and is close to the consumer's house or store that is the requesting source. A plurality of delivery bases are searched from the base DB 144. Then, the server 1 outputs a delivery request to the corresponding base terminal 6 so as to deliver the food from one of the searched delivery bases.

Here, the server 1 may set the selling price of each food as a predetermined price, but in the present embodiment, the selling price of each food is set according to the freshness information of the food, the delivery cost from the delivery base, and the like. Fluctuate.

For example, the server 1 refers to the read data of the packing tag 3 stored in the packing DB 142, and estimates the freshness information according to the storage time, storage temperature, etc. of the food at the delivery base. The server 1 may use not only the storage status at the delivery base but also the storage status in the transportation process from the production area to the delivery base for freshness estimation. The server 1 determines the selling price so that the better the freshness, the higher the selling price.

Further, for example, the server 1 estimates the delivery cost according to the distance between the delivery base and the delivery destination (consumer's house or store), the delivery time zone (whether daytime or nighttime), and the like. For example, the server 1 searches a plurality of delivery bases located within a predetermined range from the consumer's house or store from the base DB 144, and estimates the delivery cost when delivering from each base. The server 1 determines the selling price according to the delivery cost of the base, assuming that the food is delivered from the base having the lowest delivery cost.

As described above, the server 1 changes the selling price according to the food storage status at the delivery base, the delivery cost, and the like. When the terminal 2 accepts the food selection input, the server 1 determines the selling price, outputs various information including the determined selling price and the freshness information to the terminal 2, and displays the ordering screen of FIG. 7B on the terminal 2. To display.

The ordering screen is a screen for accepting an ordering request for the selected food. For example, on the ordering screen, the terminal 2 displays the selling price, freshness information, etc. of the food selected by the user, and accepts the quantity of the food to be ordered, the desired delivery time, etc. Accept order requests.

In this case, even if the type of food is selected by the user, the terminal 2 separately sells, freshness information, etc. according to the food group for each package stored in the delivery base or each food (individual). By displaying, it is possible to specify the packaging or individual of the food to be ordered and place an order.

As described above, the server 1 manages the server 1 at the delivery base for each packing unit based on the packing tag 3 or for each food unit based on the individual tag 4. Therefore, the server 1 estimates the freshness information of each food in the packing unit or the individual food unit, and determines the selling price. For example, according to the example of FIG. 7B, even if the same "apple" is used, the freshness information and the selling price are set to different values if the packing and the individual are different. Therefore, the server 1 presents different freshness information, selling prices, etc. according to each food (packing or individual) stored in the delivery base, and allows the user to select the food.

The terminal 2 accepts a designated input for designating one of the foods displayed separately above, and outputs an order request for the designated food to the server 1. When the order request is received from the terminal 2, the server 1 outputs a delivery request for delivering the food specified in the base terminal 6 of the delivery base to the delivery destination (consumer's house or store), and the ordered food. To be delivered.

From the above, by combining the packing tag 3 and the individual tag 4, it is possible to track the freshness of food in the entire distribution process from the place of production to the final consumer. In addition, the user can not only grasp the freshness information of the food at hand, but also can order the food, which can improve the convenience of the user.

FIG. 8 is a flowchart showing an example of the procedure of food management processing. Based on FIG. 8, the contents of the process of acquiring the data of each food in the distribution process from the packing tag 3 and the individual tag 4 and storing and managing the data in each database will be described.
The server 1 accepts registration of food information regarding foods shipped from the production area (step S11). The food information registered in step S11 includes, for example, the name of the food to be shipped, the producer, the place of production, the production conditions, and other information related to the food itself, as well as the individual tag 4 individually attached to each food. It includes an individual ID, a packing ID of a packing tag 3 attached to a packing body for packing food at the time of transportation, information on the packing body and / or a film 7 for packing individual foods, and the like.

The server 1 is data (first data) obtained by reading the packing tag 3 from a transport vehicle (moving body) that transports food from the production area to the delivery base, and is possessed by the packing tag ID and the packing tag 3. Various data including the environmental data of the loading platform (space) of the transport vehicle detected by the sensor are acquired and stored in the packing DB 142 (step S12). The sensor of the packing tag 3 is, for example, a temperature sensor, and the server 1 acquires the storage temperature of food in the transport vehicle from the packing tag 3.

The server 1 determines whether or not the food has arrived at the delivery base based on the read data of the packing tag 3 notified from the base terminal 6 (step S13). If it is determined that the delivery base has not arrived (S13: NO), the server 1 returns the process to step S12. When it is determined that the food has arrived at the delivery base (S13: YES), the server 1 refers to the packing DB 142 and requests an order (ordering information) for a film (packaging material) for packaging the food package that has arrived at the delivery base. Output to a predetermined film supplier (step S14).

The server 1 acquires data (first data) obtained by reading the packing tag 3 at the delivery base, including the packing tag ID and the environmental data in the base detected by the sensor of the packing tag 3. Then, it is stored in the packing DB 142 (step S15).

The server 1 determines whether or not the food has been shipped from the delivery base based on the read data of the packing tag 3 or the individual tag 4 notified from the base terminal 6 (step S16). If it is determined that the server has not been shipped (S16: NO), the server 1 returns the process to step S15. When it is determined that the food has been shipped (S16: YES), the server 1 outputs a collection request (collection information) of the packing tag 3 that has packed the shipped food to the packaging company (step S17). The server 1 reads data including an individual ID obtained by reading the individual tag 4 from a store terminal 2b connected to the reader 5c or a refrigerator 8 in a consumer's house having the reader 5d, and a food storage temperature at the time of reading. Is acquired and stored in the individual DB 141 (step S18). The server 1 ends a series of processes.

FIG. 9 is a flowchart showing an example of the procedure of the deadline output process. Based on FIG. 9, the processing content when the freshness information of the food is output from the server 1 to the terminal 2 will be described.
The terminal 2 (consumer terminal 2a or store terminal 2b) requests the server 1 to output the freshness information of the food stored under the user (consumer or store) (step S31). When the output request for freshness information is received, the server 1 identifies the individual ID of each food product stored at the request source for freshness information (step S32). For example, the server 1 refers to the individual DB 141 and identifies the food in which the reader ID of the refrigerator 8 in the consumer's home or the reader ID of the reader 5c in the store is associated with the individual ID.

The server 1 refers to the individual DB 141 and the packing DB 142, estimates the freshness information indicating the expiration date, the best time to eat, etc. of each food, and outputs it to the terminal 2 (step S33). For example, the server 1 has a time-series transition of environmental data (temperature, etc.) acquired based on the packaging tag 3, and a time-series transition of storage temperature at a consumer's house, store, etc. acquired based on the individual tag 4. In addition, the freshness information of the food is estimated by referring to, for example, the type of food, the production conditions, the package body and / or the type of the film 7 for packaging each food.

When the freshness information is acquired from the server 1, the terminal 2 displays a list of freshness information of each food (step S34). For example, the terminal 2 displays foods that reach the deadline within a predetermined period and other foods in different modes by color coding or the like.

The terminal 2 accepts a selection input for selecting one of the foods whose freshness information is displayed in a list, and notifies the server 1 of the selection result (step S35). The server 1 is a delivery base in which the selected food is stored, and searches one or more delivery bases close to the food delivery destination (consumer's house or store) from the base DB 144 (step S36).

The server 1 estimates the freshness information based on the data (first data) of the corresponding food at the searched delivery base, which is acquired from the packing tag 3 and stored in the packing DB 142 (step S37). In addition to the estimated freshness information, the server 1 determines the selling price of the food according to the distance between the delivery base and the delivery destination, and outputs the food to the terminal 2 (step S38). The terminal 2 displays an ordering screen showing freshness information, selling price, etc. of each food in a packing unit or an individual food unit, accepts input of the quantity of food to be ordered, desired delivery time, etc., and sends an order request to a server. Output to 1 (step S39). When the order request is received, the server 1 outputs the delivery request of the food to the base terminal 6 (step S40), and ends a series of processes.

In the above, as the reading medium attached to each food, the individual tag 4 that performs short-range wireless communication with the reader 5 is used, but the present embodiment is not limited to this. For example, instead of the individual tag 4, code information such as a QR code (registered trademark) and a barcode is assigned, and a camera is installed in a storage place such as a refrigerator 8 to optically read the code information to obtain an individual ID. May be obtained. That is, the server 1 may be able to acquire an individual ID based on a reading medium individually attached to the food, and the reading medium is not limited to the wireless tag.

Further, in the above, it was decided to collect data such as storage temperature from the refrigerator 8 of the consumer's house or the store also in the distribution process (second distribution process) after being shipped from the delivery base. Is not limited to this. For example, the server 1 may be configured to only acquire individual IDs from readers 5c and 5d, and not to acquire the storage temperature. In this case, for example, the server 1 estimates the freshness information in the distribution process (first distribution process) based on the data acquired from the packing tag 3, and then determines the current time from the elapsed time after being shipped from the delivery base. Just estimate the freshness information. That is, the server 1 only needs to be able to acquire at least the ID of the individual tag 4 and estimate the freshness information, and it is not essential to have a configuration that manages the storage temperature of food and the like in the distribution process after being shipped from the delivery base.

From the above, according to the first embodiment, by combining the packing tag 3 and the individual tag 4, it is possible to acquire the data of the entire distribution process from the production area to the consumer and estimate the freshness information, and the freshness of the food can be estimated. Can be managed appropriately.

Further, according to the first embodiment, by providing the temperature sensor, the humidity sensor, the gas sensor and the like on the packing tag 3, the freshness of the food in the distribution process can be appropriately managed.

Further, according to the first embodiment, the freshness of food can be managed more appropriately by estimating the freshness information according to the type of the package or the film 7 (packaging material) for packaging each food. it can.

Further, according to the first embodiment, when the use of the film 7 is completed, an order request for a new film 7 is output to the film supplier, so that the smooth distribution can be supported.

Further, according to the first embodiment, when the use of the packing tag 3 is completed, the collection request of the packing tag 3 is output to the packaging company, so that the smooth distribution can be supported.

Further, according to the first embodiment, the food stored in the consumer's home is stored in the consumer's home by reading the individual tag 4 in the refrigerator 8 in the consumer's home to obtain the storage temperature and presenting the freshness information to the consumer. The freshness of the food can be managed appropriately.

Further, according to the first embodiment, it is possible to provide not only the BtoC service for managing the freshness of food in the consumer's home but also the BtoB service for stores.

Further, according to the first embodiment, the environmental data (temperature, etc.) detected by the sensor of the packing tag 3 is acquired from the transport vehicle (moving body) that transports the food, and the control information of the air conditioner is output. , It is possible to optimize the freshness management during transportation.

Further, according to the first embodiment, not only the freshness information is presented, but also the convenience of the user is improved by accepting the order request of the food showing the freshness information and enabling the food to be sent directly from the delivery base. be able to.

Further, according to the first embodiment, the selling price of the ordered food is determined by the freshness information estimated from the storage status at the delivery base, or the freshness or the like according to the distance from the delivery base to the delivery destination. The selling price can be set dynamically in consideration of this.

(Embodiment 2)
In this embodiment, a mode for recommending consumers to consume foods whose deadline is near, such as when to eat, will be described. The contents overlapping with the first embodiment are designated by the same reference numerals and the description thereof will be omitted.
FIG. 10 is a block diagram showing a configuration example of the server 1 according to the second embodiment. The auxiliary storage unit 14 of the server 1 according to the present embodiment stores the cooking DB 146. The cooking DB 146 is a database that stores information on cooking using various foods provided by this system.

FIG. 11 is an explanatory diagram showing an example of the record layout of the cooking DB 146. The dish DB 146 includes a dish ID column, a dish name column, a recipe column, and an ingredient column. The dish ID column stores an ID for identifying each dish. Each of the dish name column, the recipe column, and the ingredient column stores information on the dish name, the dish recipe (cooking method), and necessary ingredients (food) in association with the dish ID.

FIG. 12 is an explanatory diagram showing an example of a dish list screen. An outline of the present embodiment will be described with reference to FIG.
In the present embodiment, the server 1 recommends to the consumer that among the foods stored in the refrigerator 8 of the consumer's home, the foods that reach the deadline such as the time to eat within a predetermined period, that is, the foods that are near the deadline The recommended information for the above is generated and output to the consumer terminal 2a. The recommended information is, for example, cooking information indicating a dish using a food that is about to expire.

For example, the consumer terminal 2a displays a food list screen that displays foods that are about to expire in a manner different from other foods, as in the first embodiment (see FIG. 7A). As a result, the consumer terminal 2a recommends the consumer to consume the food concerned. On the list screen, the consumer terminal 2a accepts a selection input for selecting a food that is about to expire. When the selection input is accepted, the consumer terminal 2a communicates with the server 1 and acquires cooking information related to cooking using the selected food.

For example, the server 1 periodically (for example, every other day) determines whether or not the food at the consumer's home is nearing the deadline, and if it determines that the deadline is approaching, it automatically determines that the deadline is approaching. It may be notified to and output cooking information. That is, the server 1 may output recommended information for recommending the consumption of food near the deadline to the consumer terminal 2a, and the output trigger may be manual or automatic.

When the food information is acquired from the server 1, the consumer terminal 2a transitions to the food list screen shown in FIG. 12 and displays a list of a plurality of dishes using the selected food. For example, as shown in FIG. 12, the consumer terminal 2a displays a list of cooking names, necessary ingredients (foods), recipes (cooking methods), and the like for each dish. As a result, the consumer can appropriately cook and consume foods whose expiration date is approaching or foods that have reached the time when they are ready to eat, and can prevent foods from being discarded.

In this embodiment, not only the food information is presented, but also the order request for other foods (ingredients) necessary for the presented food is received and delivered to the consumer's home. For example, the consumer terminal 2a accepts a selection input for selecting one of the dishes on the dish list screen, and is another food necessary for the selected dish and is not stored in the refrigerator 8 of the consumer's house. Accept order requests to order food.

For example, the consumer terminal 2a accepts the food selection input on the food list screen of FIG. 7A, receives the specified input of the time to start cooking, that is, the desired delivery time of other foods, and notifies the server 1 of the input contents. .. The server 1 searches the cooking DB 146 for a dish using the selected food, and identifies other foods required for the searched dish.

In this case, the server 1 refers to the individual DB 141 to specify each food stored in the refrigerator 8 of the consumer's home, and from the other foods specified above, the food already existing in the consumer's home is It may be excluded. This makes it possible to prevent the situation where extra food is ordered.

Server 1 is a delivery base that stores other specified foods, and searches for one or more delivery bases near the consumer's home. Then, the server 1 refers to the data of the other foods stored in the searched delivery base from the packing DB 142, and estimates the freshness information of the other foods. The server 1 estimates the delivery cost from the distance from the delivery base to the delivery destination (consumer's house) in addition to the freshness information, and determines the selling price of the other food based on the freshness information and the delivery cost.

The server 1 outputs various information including cooking information, freshness information, selling price, etc. to the consumer terminal 2a, and displays the cooking list screen of FIG. In this case, the consumer terminal 2a ranks and displays a list of each dish according to the freshness information, selling price, and the like of other foods required for each dish. For example, the consumer terminal 2a accepts a selection input of a ranking standard, whether to rank by freshness information (freshness) or selling price, by operating input to the selection field 121 at the top of the screen. The consumer terminal 2a displays each dish in order from the top based on the selected criteria.

The consumer terminal 2a accepts a selection input for selecting one of the dishes displayed on the dish list screen, receives an order request for other foods used for the selected dish, and outputs the order to the server 1. The server 1 outputs a delivery request to the base terminal 6 according to the order request output from the consumer terminal 2a, and delivers the ordered other food to the consumer's home at a designated time.

In the above, each dish is ranked and presented according to the freshness information (freshness) required for the dish, the selling price, etc., but for example, the server 1 consumes according to the food order history by the consumer. The taste of the person may be analyzed, and the food using the food suitable for the taste of the consumer may be preferentially presented. For example, the server 1 stores the food order history by the consumer in the user DB 145, and determines whether the consumer gives priority to the price or the freshness from the price, freshness information, etc. of each food ordered in the past. Determine if it is the preferred consumer. The server 1 determines the priority criteria for ranking according to the determination result, ranks each dish, and outputs the ranking to the consumer terminal 2a. As a result, dishes suitable for the taste of the consumer are preferentially presented.

FIG. 13 is a flowchart showing an example of the procedure for deadline notification processing according to the second embodiment. After the server 1 estimates the freshness information of each food stored in the refrigerator 8 of the consumer's house and outputs it to the consumer terminal 2a (step S33), the consumer terminal 2a executes the following processing.
The consumer terminal 2a displays a list of freshness information of each food product stored in the refrigerator 8 of the consumer's home (step S201). In this case, the consumer terminal 2a displays the food that reaches the deadline within a predetermined period, that is, the food that is recommended for consumption, in a manner different from that of other foods. The consumer terminal 2a accepts a selection input for selecting a food recommended for consumption, receives a designated input for designating a time to start cooking, and notifies the server 1 (step S202).

When the notification is received from the consumer terminal 2a, the server 1 searches the cooking DB 146 for a dish using the selected food, and identifies other foods required for the searched dish (step S203). The server 1 searches the base DB 144 for one or a plurality of delivery bases that are storage bases for other specified foods and that can be delivered by a designated time and are close to the consumer's home (step S204).

The server 1 is the data of the other foods stored in the searched delivery base, and is based on the data (first data) acquired from the packing tag 3 stored in the packing DB 142 of the other foods. Estimate freshness information (step S205). In addition to the estimated freshness information, the server 1 determines the selling price of the other food according to the distance between the delivery base and the delivery destination (consumer's house), and the dish indicating the dish using the selected food. Information, freshness information of other foods required for the dish, selling price, etc. are output to the consumer terminal 2a (step S206).

The consumer terminal 2a displays a list of a plurality of dishes using the food selected in step S202 (step S207). Specifically, the consumer terminal 2a ranks and displays a list of a plurality of dishes based on the freshness information, selling price, and the like of other foods acquired from the server 1. The consumer terminal 2a accepts a selection input for selecting one of the displayed plurality of dishes, receives an order request for other foods required for the selected dish, and outputs the request to the server 1 (step S208). When the order request is received, the server 1 outputs the delivery request of the other food to the base terminal 6 (step S209), and ends a series of processes.

From the above, according to the second embodiment, by recommending the consumer to consume the food near the deadline, it is possible to prevent the disposal of the food and improve the convenience of the consumer.

Further, according to the second embodiment, by presenting cooking information as recommended information, it is possible to more preferably promote the consumption of food.

Further, according to the second embodiment, it is possible to further improve the convenience of consumers by accepting orders for other foods necessary for cooking.

Further, according to the second embodiment, the consumer considers the freshness and cost of the food by ranking and presenting a plurality of dishes according to the freshness information and the selling price of other foods necessary for cooking. You can decide the dish.

Further, according to the second embodiment, it is possible to make a recommendation suitable for the taste of the consumer by determining the recommended dish by referring to the history of ordering food by the consumer.

(Modification example)
In the first embodiment, it has been described that the packing tag 3 and the individual tag 4 are combined to manage the freshness. In this modification, a mode in which freshness management is performed by one type of tag instead of combining two types of tags will be described.

FIG. 14 is a schematic diagram showing a configuration example of a food management system according to a modified example. In this modification, the wireless tags 9 attached to the individual foods are read by the readers 5 distributed in the distribution process, and the freshness is managed.

The wireless tag 9 is an RFID tag provided with a sensor that detects ambient environmental data like the packing tag 3, but unlike an ordinary RFID tag, a part or all of the constituent members except the IC chip is an organic medium. An RFID tag produced by printing an organic medium that is configured and functions as each member on a substrate. Specifically, the wireless tag 9 includes an organic medium such as a sensor for detecting environmental data, wiring for electrically connecting the IC chip and other members, and an antenna for wireless communication with the outside. A sensor, wiring, etc. are formed by placing an IC chip on a predetermined substrate (for example, an insulating thin film) and applying an organic medium such as a conductive silver ink or a polymer with a dispenser. .. Since it is produced by printing (coating) an organic medium, the wireless tag 9 is produced at a lower cost than a general RFID tag.

The wireless tag 9 is attached to the film 7 of each food, and the identification information of each food is assigned. The wireless tag 9 is read by each reader 5 distributed in a transport vehicle, a delivery base, a store, a user's home, etc., and the server 1 acquires data including identification information and environmental data read by each reader 5. And store it in the database. The server 1 estimates the freshness information of the current food based on the data obtained by reading the wireless tag 9.

The following appendix is disclosed with respect to this modification.
(Additional note)
A wireless tag composed of a part or all of the constituent members excluding the IC chip printed on an organic medium, which is attached to a packaging material for packaging food, to which identification information of the food is assigned, and A wireless tag having a sensor for detecting ambient environment data is acquired by reading data read by reader devices distributed in the food distribution process.
Based on the data, the freshness information of the food is estimated and
A food management method, characterized in that a computer executes a process of outputting the estimated freshness information.
