Description

[Technical field]

[0001] The present invention relates to a navigation system that guides a user to a destination, and more particularly to a navigation system that guides a route from a user's current location to a place that sells a food desired by the user. [Background technology]

[0002] In recent years, efforts have been made to reduce food waste, which is the loss caused by throwing away food that is still edible. Food waste is not just a waste of food resources; it also leads to high costs for the disposal of garbage generated by discarding food, and it places a burden on the environment due to the emission of large amounts of greenhouse gases when it is burned as combustible waste, and the landfilling of ash generated after incineration of combustible waste. Therefore, in addition to efforts to prevent food waste by individuals, businesses are being asked to create efforts and systems to reduce so-called commercial food waste that occurs as a result of business activities.

[0003] As an example of such a system, Patent Document 1 discloses a point-granting system configured to grant points according to the menu ordered by a customer who visits a restaurant. The point-granting system described in Patent Document 1 includes an ordering terminal, a point calculation terminal, and a point-granting terminal. The ordering terminal is configured to display the points granted for each menu, so that the customer can order the menu while referring to the points granted. The ordering terminal transmits the menu ordered by the customer to the point calculation terminal, and a point calculation process is performed according to the menu. The point calculation terminal determines the points to be granted based on a point table in which the allocation and grant rate of points are set according to the consumption amount of each ingredient consumed in each menu, the stock amount of the ingredient consumed, and the expiration date of the ingredient consumed. The determined points are then granted to a point card or the like presented by the customer via the point-granting terminal. According to Patent Document 1, the points granted to the customer are set to be larger for ingredients that are approaching their expiration date or ingredients that are used in large quantities and have a large inventory. With such a configuration, ingredients that are approaching their expiration date or ingredients that are likely to remain in large quantities can be effectively consumed, thereby reducing food waste.

[0004] [Patent Document 1] JP 2008-257496 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the system described in Patent Document 1, the menu items with high points are displayed on the ordering terminal, and the ordering terminal is installed at the seating area of ​​the restaurant or the like. Therefore, the customer cannot know which ingredients or menu items with high points are given until he or she goes to the restaurant and checks the display on the ordering terminal. Even if the customer visits the restaurant or the like, the customer may not be able to eat ingredients that are close to their expiration date, are in stock, or are consumed in large quantities at the restaurant or the like because the customer dislikes or has an allergy to them. In such cases, the customer is forced to order a menu that does not directly contribute to reducing food waste, which may lead to a loss of opportunities to reduce food waste. Furthermore, since the system requires customers to look at the menu on the ordering terminal when they visit the restaurant and place their order, only a limited number of businesses can introduce this system. For example, the system cannot be introduced in supermarkets or food trucks, so the effect of reducing food waste may be limited.

[0006] In addition, customers must check for themselves whether restaurants and other establishments have implemented the system described in Patent Document 1. Therefore, in order for new customers to visit restaurants that have implemented this system, they must investigate it themselves, and even if they find such a restaurant, they must investigate the store's location and route themselves. If a detailed search for the store's location and route reveals that the store is far away or in a location that is difficult to access, the customer may give up on visiting the store. In other words, due to such inconvenience for customers, there is a risk that restaurants and other establishments that are implementing the above-mentioned initiatives will find it difficult to attract new customers, and ultimately there is a possibility that opportunities and opportunities to reduce food waste will be lost.

[0007] This invention has been made in response to the above technical problems, and aims to provide a navigation system that can guide a user to stores that sell the desired food and promote the reduction of food waste. [Means for solving the problem]

[0008] In order to achieve the above object, the present invention provides a navigation system that guides a user to a predetermined food store among at least one food store based on information input from a user terminal to a server, the navigation system including a user information acquisition unit that acquires information about the user including location information of the user and desired food input by the user, a store information acquisition unit that acquires information about the food store including the location of the at least one food store and information about food that should be consumed early that is registered from the at least one food store, and a store information acquisition unit that acquires information about the food store including information about food that should be consumed early that matches the desired food input by the user from the foods that should be consumed early that are registered from the at least one food store. the user terminal includes a food information matching unit that matches the desired food with the food that should be consumed early; a store information notification unit that notifies the user terminal of information regarding the food that should be consumed early that matches the desired food and information about the at least one food store that has registered the food that should be consumed early that matches the desired food; a route setting unit that sets a route from the user's current location obtained based on the user's location information to the specified food store, which is a food store selected by the user from the at least one food store notified to the user; and a route guidance unit that guides the user along the route from the user's current location set by the route setting unit to the specified food store. Effect of the Invention

[0009] According to this navigation system, food that is judged to be consumed early due to factors such as expiration date and inventory amount at food stores that handle food, ingredients, and dishes is registered in a server. Then, when a user inputs a desired food from a user terminal, the server checks whether the desired food is registered as a food that should be consumed early. As a result, if a matching food is found, information such as expiration date of the food and information such as the location of the food store that has registered the food are notified to the user terminal. When the user selects one of the notified food stores, a route from the user's current location to the food store selected by the user is set and displayed on the user terminal. Therefore, by inputting the name of the food or the product name from the user terminal, the user can know in advance which food stores may discard the food or product without visiting the food store. This can avoid or reduce the need for the user to investigate the food store's efforts regarding food waste and the loss of an opportunity to reduce food waste despite the user visiting the food store. In addition, even if the user has never been to a food store, information about the store, including its location, is notified to the user terminal, reducing the need for the user to research such store information and routes by themselves, and reducing the burden on the user even when visiting a store for the first time. In other words, the user can easily receive information about foods and food stores that meet the user's needs, thereby efficiently reducing food waste. Furthermore, the user terminal is notified of stores that may generate food waste and the amount of food that will be discarded, which leads to more opportunities for the user to learn about food waste and further promotes the reduction of food waste. [Brief description of the drawings]

[0010] [Figure 1] 1 is a schematic diagram showing a configuration of a navigation system according to an embodiment of the present invention. [Diagram 2] 4 is a diagram for explaining a process of processing executed in the navigation system according to the embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The present invention will be described below based on the embodiment shown in the drawings. Note that the embodiment described below is merely one example of a specific embodiment of the present invention, and is not intended to limit the present invention.

[0012] First, an example of the configuration of a navigation system 1 in an embodiment of the present invention will be described with reference to Figures 1 and 2. As shown in Figure 1, the navigation system 1 in this embodiment is mainly composed of a store terminal 3 operated in a plurality of stores 2 including a food store, a car navigation system 5 installed in a plurality of vehicles 4, and a server 6. These are connected to each other via a network (not shown) so as to be able to communicate with each other and are configured so as to be able to send and receive data to each other. Note that the network referred to here may be, for example, a public communication network such as the Internet, a WAN [Wide Area Network] which is a wide area information communication network, a telephone communication network such as a mobile phone or a wireless communication network, or other communication network, or any other conventionally known communication network.

[0013] The store terminal 3 is managed or registered in the server 6, and is an appropriate terminal device equipped with, for example, a communication unit, a control unit, a storage unit, an input / output unit, etc. (not shown). The store terminal 3 may be a terminal dedicated to the navigation system 1, or may be an information processing device including a smart device (smartphone, personal computer, tablet terminal, etc.) with a predetermined application installed. The store terminal 3 allows input of food, ingredients, dishes, etc. (hereinafter, may be simply referred to as food) in the store 2. Specifically, for example, in the case of a supermarket, information such as specific food names, product names, contents, origin, price, stock amount, and discount information is included. Alternatively, in the case of a restaurant, information such as specific dish names, foods and ingredients used, prices, allergy information, and discount information is included. Such information is not limited to being registered by an employee of the store 2 operating the store terminal 3, but may be configured to automatically input information about food by linking with an application that manages the food of the store 2. It should be noted that the store 2 referred to here is a supermarket, restaurant, or greengrocer that handles food and ingredients, but is not limited to a building and may be, for example, a food truck, a food stall, or other mobile establishment that sells food or dishes, or a food manufacturing factory, etc.

[0014] The car navigation system 5 is mounted on the vehicle 4, and is configured to guide the user 7 to the destination by incorporating map data and facility information data, searching for information on the destination and facilities around the current location, and displaying the information on the map using a display unit (not shown). The car navigation system 5 is managed or registered in the server 6, similar to the store terminal 3, and is an appropriate terminal device equipped with, for example, a communication unit, a control unit, a storage unit, an input unit, and an output unit (not shown). The car navigation system 5 is configured to perform data communication with the server 6, for example, via a DCM [Date Communication Module]. The car navigation system 5 is also equipped with a self-position estimation function such as a GPS (Global Positioning System) that receives signals transmitted by multiple satellites and estimates the current location based on the signals. In addition to the above functions, the car navigation system 5 is configured to allow the user 7, the driver or passenger, to input food and the like that he or she desires. Specifically, the food and product name and dish name that the user 7 desires, and when inputting the dish name, the user 7 can input food that cannot be eaten due to allergies, etc. This information is then configured to be transmitted to the server 6 via a communication unit or the like.

[0015] Furthermore, the car navigation system 5 is configured to receive, when a food item matching the food item input by the user 7 is found in the server 6, information about the store 2 that sells that food item from the server 6. That is, the car navigation system 5 receives and displays information transmitted from the server 6, such as the address of the store 2 that has registered the desired food item, and information about the expiration date, stock amount, price, etc., of the desired food item registered by the store 2. The car navigation system 5 is configured to transmit the information about the selected store 2 to the server 6 by allowing the user 7 to select one store 2 via a specified user interface based on the received information about the multiple stores 2 and foods.

[0016] The car navigation system 5 is also equipped with an electronic toll collection system (not shown) capable of receiving a driving assistance system based on a conventionally known road-vehicle cooperative system, or is configured to link the car navigation system 5 with the electronic toll collection system installed in the vehicle 4. The electronic toll collection system is configured to receive wide-area congestion information and regulation information, safe driving assistance, etc., pay tolls for expressways, and also be used for payment at restaurants and the like via the electronic toll collection system, by two-way communication using ITS spots (Intelligent Transport Systems) installed mainly on expressways and DSRC (Dedicated Short Range Communication: Spot Communication), which is mainly a dedicated short-range communication.

[0017] The communication function of the car navigation 5 does not have to have a function of directly communicating with the server 6. In that case, the communication with the server 6 may be performed by another mobile terminal that can communicate with the car navigation 5 and has software such as a predetermined application installed. In that case, the user 7 inputs information about food to the server 6 using the other mobile terminal, and receives information about the matching food and information about the store 2 that handles the food on the mobile terminal. Then, the user 7 may input a destination, etc. to the car navigation 5 based on the received result and the location of the store 2, or the car navigation 3 may receive data from the mobile terminal, and a route may be displayed on an output device such as a display in the car navigation 3. The car navigation 5 may also be configured to have the above-mentioned communication function in cooperation with a communication support service such as T-connect (registered trademark). The car navigation 5 corresponds to the user terminal in the embodiment of the present invention.

[0018] The vehicle 4 equipped with this car navigation system 5 may be an existing general vehicle 4 (such as an engine vehicle, an electric vehicle, a hydrogen vehicle, a hybrid vehicle, or a fuel cell vehicle). The vehicle 4 is not limited to a manually driven vehicle 4 that travels to a destination by a driver performing driving operations, but may be an automatically driven vehicle that travels to a destination by automatically controlling driving operations without relying on the driver's driving operations.

[0019] The server 6 is a computer that provides services, and has a function of providing information and processing results based on various commands received. Specifically, the server 6 includes a processor such as a CPU, a main memory such as a RAM or a ROM, and an auxiliary memory such as an SSD, a hard disk drive, and a removable medium. The removable medium may be, for example, a USB memory or a disk recording medium such as a CD or a DVD. The auxiliary memory stores an operating system (OS), various programs, various tables, and the like, and is configured to realize each function that meets a predetermined purpose by executing the stored programs with a processor. The server 6 includes a user information acquisition unit 8, a store information acquisition unit 9, a food information collation unit 10, a store information notification unit 11, a route setting unit 12, and a set store notification unit 13, each of which is provided in an appropriate device within the server 6.

[0020] When the user information acquisition unit 8 receives a signal indicating that a food name, a product name, or a dish name has been input from a user 7 such as a driver or a passenger via the car navigation system 5, it acquires information about the user 7. The information about the user 7 includes, for example, information about the desired food such as the input food, ingredients, or dish, as well as the current location based on the location information of the vehicle 4 in which the user 7 is riding, obtained from GPS information. Alternatively, since the input of the dish name may require a reservation at a restaurant or the like, information such as the name or nickname may be acquired. Furthermore, if the user 7 has used the navigation system 1 in the past, a past usage history such as previously used stores 2 and purchased foods may be acquired from a storage unit (not shown) of the server 6.

[0021] The store information acquisition unit 9 acquires foods to be consumed early in the store 2 registered via the store terminal 3, and information on those foods. The foods to be consumed early here refer to foods that are nearing their expiration date or best-before date, foods that are likely to be discarded due to a large amount of stock in the store 2, or foods that are discarded because they are scraps of food processed in a factory or are out of standard. The store information acquisition unit 9 acquires information on such foods to be consumed early, such as specific food names and product names, their contents, place of origin, price, stock amount, discount information, or dish names, foods and ingredients used in the dishes, prices, allergy information, and discount information. In addition to these pieces of information, if it is a supermarket, basic information on the store 2, such as the store name, location, business hours, telephone number, payment method, and availability of parking, may be acquired. Alternatively, if it is a restaurant, information on the number of seats and whether smoking is prohibited may be acquired.

[0022] Furthermore, when the store information acquisition unit 9 receives information on the store 2 and food that was introduced to the user 7 from the set store notification unit 13, it reduces and manages the inventory of the corresponding food stored in the store information acquisition unit 9. Furthermore, if necessary, it notifies the store terminal 3 of the store 2 that was introduced to the user 7 via a notification unit (not shown) that the user 7 has been introduced. The content of the notification may be, for example, user information such as the food ordered by the user 7 and the arrival time of the user 7 calculated by the route setting unit 12.

[0023] The food information matching unit 10 acquires information on food desired by the user 7 acquired by the user information acquisition unit 8 and information on food to be consumed early that is registered from the store 2 acquired by the store information acquisition unit 9, and checks whether they match. If a food that matches the food desired by the user 7 is registered, information on that food is also acquired. When a specific dish name is input, not only is it possible to search for a store 2 that has registered the specified dish, but it is also possible to match stores that have ingredients necessary to make the specified dish as matching stores 2. In this case, for example, for fresh ingredients, it is possible to match stores 2 that have registered at least one food that should be consumed early as matching stores, and other ingredients do not necessarily have to be foods that should be consumed early.

[0024] The store information notification unit 11 notifies the user 7 of information on food that matches the food desired by the user 7 matched and acquired by the food information matching unit 10, and information on at least one store 2 that has registered the food desired by the user 7. In other words, if there are multiple stores 2 that have registered the food desired by the user 7, the store information notification unit 11 is configured to obtain information such as the addresses of the multiple stores 2 and information such as the expiration date, stock amount, price, etc. of the food registered at each store 2, and transmit this information to the car navigation system 5 of the user 7.

[0025] The route setting unit 12 acquires a route from a plurality of stores 2 that have registered the desired food, which is notified to the car navigation system 5 by the store information notification unit 11, to a predetermined store 2 selected by the user 7. First, the route setting unit 12 acquires information such as the location of the predetermined store 2 acquired by the store information acquisition unit 9, and information regarding the current location of the vehicle 4 in which the user 7 rides acquired by the user information acquisition unit 8. Then, the route setting unit 12 acquires map data and facility information stored in a storage unit (not shown), and searches for an optimal route or a shortest route from the current location of the vehicle 4 to the location of the predetermined store 2, for example, using the Dijkstra algorithm. Furthermore, the route setting unit 12 is configured to calculate the required time to travel the shortest route based on predetermined conditions, and to acquire road information and traffic congestion information from infrastructure facilities such as roadside units, and to finally calculate the required time from the current location of the vehicle 4 to the predetermined store 2.

[0026] The set store notification unit 13 corresponds to the route guidance unit in the embodiment of the present invention, and is configured to transmit the route set by the route setting unit 12 to the car navigation system 5. Also, it is configured to set the predetermined store 2 selected by the user 7 as the guided store 2, and transmit information on the predetermined store 2 and food, etc. to the store information acquisition unit 9 as necessary. After completing the transmission of information to the car navigation system 5 and the store information acquisition unit 9, it is configured to transmit information on the predetermined store 2 and food guided to the user 7 to the user information acquisition unit 8 and associate it with the information of the user 7.

[0027] Next, with reference to FIG. 2, we will explain the sequence of events in this navigation system 1, from when food is registered in the server 6 from the store terminal 3, when the food desired by the user 7 is input in the server 6 from the car navigation 5, when the user 7 travels to the specified store 2, and when the user 7 picks up the food.

[0028] First, information about food is registered from the store terminal 3 to the server 6 by an employee of the store 2 operating the store terminal 3, or by a predetermined application that manages the inventory of the store 2 linked to the store terminal 3. That is, as described above, foods that should be consumed early are registered in supermarkets, restaurants, etc., and information about the foods, such as the specific food name, product name, content amount, place of origin, price, inventory amount, discount information, foods and ingredients used in the dish, and allergy information, is registered in the store information acquisition unit 9 of the server 6. Note that basic information about the store 2, such as the location and business hours, may be stored in advance in the memory unit of the server 6.

[0029] Furthermore, the user 7 inputs the desired food into the car navigation system 5 using a predetermined user interface. The information to be input at this time is the name of the food, the name of the ingredient, the name of the dish, etc. The input information is transmitted to the user information acquisition unit 8 of the server 6. At this time, it may be possible to set the range within which the car navigation system 5 searches for stores 2. For example, it may be possible to specify a distance within a 3 km radius from the current location or a specific station, within the range of a specific city, town, or village name, or to specify another prefecture.

[0030] The information on the food to be consumed early acquired by the store information acquisition unit 9 and the information on the food input by the user 7 acquired by the user information acquisition unit 8 are transmitted to the food information matching unit 10. Based on the information, the food information matching unit 10 searches for food matching the desired food input by the user 7 from the information acquired by the store information acquisition unit 9 within the range specified by the user 7. As a result, if the store information acquisition unit 9 has a matching food, it acquires information such as the expiration date of the food and information such as the location of the store 2 that has registered the food. When a specific dish name is input from the car navigation system 5, not only the store 2 that has registered the dish, but also the store 2 that has registered food matching ingredients etc. required to cook the dish may be searched from the store information acquisition unit 9. In addition, the store 2 that has registered many matching foods, that is, the store 2 that has registered many foods that should be consumed early as ingredients etc. required for cooking may be preferentially determined as the matching store 2. If there is no food matching the food desired by the user 7, a similar product may be presented.

[0031] If the food information collation unit 10 finds a store 2 that has registered the food desired by the user 7 within the specified range, the store information notification unit 11 acquires information about the food and the store 2 that has registered the food, and notifies the car navigation system 5 of the user 7. At that time, if there are multiple stores 2 that have registered the food desired by the user 7, all of them are notified to the car navigation system 5. In that case, the display order may be automatically rearranged based on the expiration date (best before date) and the amount of stock. The user 7 selects a specific store 2 to visit based on information such as the expiration date, amount of stock, and price of the food displayed on the car navigation system 5, and information such as the location and business hours of the store 2, and inputs to the car navigation system 5 that the user 7 will go to that store 2. At that time, the user may be configured to make a payment at the same time. That is, the electronic fee collection system linked to the car navigation system 5 as described above may be used, and the fee may be paid directly to the store 2 via the server 6 or by using so-called online payment. In addition, if the user 7 is unable to immediately go to the store 2 due to circumstances on his / her side, the reservation time, etc. may be displayed on the display unit of the car navigation system 5 so that the reservation time, etc. can be input via a specified user interface to notify the server 6.

[0032] When the predetermined store 2 selected by the user 7 is selected by the car navigation 5, the route setting unit 12 sets a route from the current position of the vehicle 4 of the user 7 to the predetermined store 2. The route setting is performed by acquiring map data and facility information stored in the storage unit of the server 6, setting an optimal route by the method described above, and calculating the required time. Note that the search for the route from the vehicle 4 of the user 7 to the predetermined store 2 may be performed by the car navigation 5.

[0033] The route set by the route setting unit 12 is then transmitted from the set store notification unit 13 to the car navigation system 5 of the user 7. Also, the system is configured to transmit information on the store 2 and food, etc. selected by the user 7 to the store information acquisition unit 9 as necessary. In particular, when the user 7 has already made payment to the store 2 using the above-mentioned electronic toll collection system or the like, the system manages the specific store 2 acquired by the store information acquisition unit so as to reduce the inventory amount according to the amount of food ordered by the user 7. Note that, once the transmission of information to the car navigation system 5 and the store information acquisition unit 9 is completed, the system is configured to link the store 2 and food introduced to the user 7 to the information on the user 7 in the user information acquisition unit 8.

[0034] The user 7 follows the route and guidance displayed on the car navigation system 5 of the vehicle 4 to the predetermined store 2 selected by the user, and goes to pick up the food. At that time, if payment has been completed, the store 2 may transmit a discount coupon that can be used on the next purchase to the car navigation system 5.

[0035] According to this navigation system 1, in a store 2 that handles food, ingredients, dishes, etc., foods that may be discarded due to factors such as expiration date and inventory amount, that is, foods that should be consumed early, are registered in the store information acquisition unit 9 from the store terminal 3. Then, when the user 7 inputs a desired food, the store information acquisition unit 9 checks whether the desired food is registered as a food that should be consumed early. As a result, if a matching food is found, information such as the expiration date of the food and information such as the location of the store 2 that has registered the food are notified to the car navigation 5. When the user 7 selects one of the notified stores 2, the route setting unit 12 is configured to set a route from the user 7's current location to the store 2 selected by the user 7 and notify the car navigation 5. Therefore, by inputting the name of the food or the product name from the car navigation 5, the user 7 can know in advance in real time which store 2 the input food may be discarded without visiting the store 2. Therefore, it is possible to avoid or reduce the need for the user 7 to investigate the store 2 about its efforts regarding food waste, and the loss of an opportunity to reduce food waste despite the user 7 visiting the store 2. In other words, since the user 7 can easily receive information on foods and food stores that meet the user 7's needs, food waste can be reduced efficiently. Furthermore, even if the user 7 has never been to a store 2, information about the store 2, including its location, is notified to the car navigation system 5, which reduces the need for the user 7 to research such information and routes about the store 2 himself, thereby reducing the burden on the user 7. Furthermore, by inputting the name of a food or product, the car navigation system 5 is notified of stores 2 that may generate food waste and the amount of food that will be discarded, which leads to more opportunities for the user 7 to learn about food waste, and further promotes the reduction of food waste.

[0036] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-mentioned examples, and may be modified as appropriate within the scope of achieving the object of the present invention. For example, the food displayed on the car navigation system 5 may be determined by machine learning based on artificial intelligence (AI). For example, the navigation system may be configured to display similar foods, stores 2 similar to the previously used store 2, or stores 2 of a similar genre to the previously used store 2, determined by machine learning such as deep learning based on basic registration information such as an address related to the user 7 who previously used the navigation system 1, the foods and dishes used, the location where the search was performed, the time of use, and a history including the store 2, etc. Alternatively, the navigation system may be configured to learn a large amount of data related to other users 7 who have similar basic registration information and usage history, and to display foods and stores 2 that the user 7 may be interested in before searching on the car navigation system 5. Furthermore, the information on foods displayed on the car navigation system 5 may be determined based on the browsing history of not only the user 7 himself but also multiple users, and the information may be displayed so that the user 7 can easily see it. Furthermore, the data is not limited to data stored in the server 6, but may be obtained from so-called big data that is accumulated in a server (not shown) of an external data center or the like and updated from time to time.

[0037] In the above-described navigation system 1, the user 7 uses the car navigation system 5 installed in the vehicle 4. However, the terminal device is not limited to the car navigation system 5, and may be, for example, an appropriate terminal device owned by the user 7. In this case, the terminal device may have a self-location estimation function using a GPS or a base station, and may be an information processing device including a device dedicated to the navigation system 1, or a smart device (smartphone, personal computer, tablet terminal, etc.) with a predetermined application installed. In this case, the route setting unit 12 may be configured to guide the user 7 on the route from the current position based on the self-location estimation function of the user 7 to the predetermined store 2 when the user 7 goes there on foot or by bicycle.
