  Among these, the article monitoring device 30 captures the stock status of the articles stored in the refrigerator 20 with the monitoring cameras 32a and 32b (hereinafter referred to as the monitoring camera 32 as appropriate), and the captured image data (ie, , An image in which the stock status of the article is captured) is transmitted to the navigation device 10, and as shown in FIG. 2, a door sensor 31a and a door sensor 31b (hereinafter referred to as the door sensor 31 as appropriate), a surveillance camera. 32, a communication processing unit 33, a control unit 34, and an image holding unit 35.

  Among these, the communication processing unit 33 is a processing unit that performs communication with the navigation device 10. Specifically, when an inventory information acquisition request for an article is received from the inventory information acquisition unit 16a in the navigation device 10, an image in which the inventory status of the article is captured by the monitoring camera 32 is transmitted as the inventory information of the article.

  The control unit 34 is a processing unit that controls the entire article monitoring apparatus 30. Specifically, the control unit 34 controls the imaging process of the inventory status of the article using the monitoring camera 32 and the response process to the inventory information acquisition request for the article.

  More specifically, the stock status of the article is imaged when the door of the refrigerator 20 is opened (that is, when the door sensor 31 detects that the door state of the refrigerator 20 is “open”). Thus, the image data of the captured image obtained by capturing the stock status of the article is stored in the image holding unit 35. When an article inventory information acquisition request is received from the inventory information acquisition unit 16a, the image data stored by the image holding unit 35 is read, and the read image data is transmitted to the navigation device 10 as article inventory information. To do.

  Here, the navigation apparatus 10 according to the present invention will be described. The navigation device 10 performs route setting of the own vehicle based on preset route information and position information of the own vehicle, and as shown in FIG. 3, an input unit 11a, an output unit 11b, a communication unit A control IF unit 12, a communication medium 13, a GPS receiver 14, a storage unit 15, and a control unit 16 are provided.

  Among these, the input unit 11a is an interface that receives an input operation from the user. For example, the input unit 11a receives an acquisition request for stock information of an article (for example, “beer”) stored in the refrigerator 20, and the stock determination unit 16b. Accepts the setting of the threshold value used for determining the inventory of articles by the above, that is, the lower limit value when determining that the inventory of articles is secured (for example, the minimum reference value “6”).

  The output unit 11b is a display device such as a liquid crystal panel or a display, and displays, for example, a navigation screen or a notification screen for article inventory information. In the present embodiment, both the input unit 11a and the output unit 11b are configured as the touch panel 11 together.

  The communication control IF unit 12 controls communication of various types of information via the communication medium 13 between the navigation apparatus 10 and the Internet 1. A GPS (Global Positioning System) receiver 14 receives information from a GPS artificial satellite, acquires time information, and specifies position information of the own vehicle. The communication media 13 may be any communication media as long as it has a communication function such as a mobile phone, a PHS, or a LAN card.

  The storage unit 15 is a storage unit (storage unit) that stores data and programs necessary for various processes performed by the control unit 16, and includes a map information storage unit 15a and a selection condition storage table 15b. Among these, the map information storage unit 15a includes information relating to various guidance objects (for example, stores such as convenience stores, supermarkets, department stores, etc.) (that is, information such as store names and addresses), and map information of the guidance objects. Are associated with each other and stored.

  The selection condition storage table 15b is a table that stores predetermined selection conditions for extracting a guidance object as a destination from a plurality of guidance objects that can be replenished with articles. And the operation when the guidance target satisfies the “selection condition” are stored in association with each other.

  More specifically, in the example shown in FIG. 4, the guidance object (that is, a store such as a convenience store, a supermarket, or a department store) that can be replenished with an out-of-stock item (in this example, “beer”) is the current position of the host vehicle 3. If the guidance target exists on the route from the location of the refrigerator 20 to the location of the refrigerator 20, the “rule 1” that extracts the guidance target as a destination candidate and the guidance target that can replenish the item “beer” that is out of stock are If the guidance target exists within a predetermined distance (for example, “1 km”) from the location, “rule 2” for extracting the guidance target as a destination candidate is held as “selection condition”.

  The reason for providing “Rule 1” as a selection condition is to guide the route to a guidance object that can be replenished without detouring out-of-stock items, and the reason for providing “Rule 2” as a selection condition is The purpose is to replenish out-of-stock items at a point close to the location of and suppress the decline in freshness of the items.

  The control unit 16 includes a control program such as an OS (Operating System), a program that defines various processing procedures, and an internal memory for storing necessary data, and is a processing unit that executes various processes using these. Particularly, those closely related to the present invention include an inventory information acquisition unit 16a, an inventory determination unit 16b, a route setting unit 16c, and an inventory information notification unit 16d.

  Among these, the inventory information acquisition unit 16a is a processing unit that makes an acquisition request for article inventory information to the article monitoring apparatus 30 and acquires the inventory information of the article. Specifically, when an acquisition request for the inventory information of an article is received from the user via the touch panel 11, or the inventory information of the article is sent from the article monitoring device 30 by making an acquisition request for the inventory information of the article every predetermined monitoring time. To get.

  The inventory determination unit 16b is a processing unit that determines whether or not the inventory of the article is insufficient based on the inventory information of the article acquired by the inventory information acquisition unit 16a. Specifically, image recognition processing is performed on image data of a captured image (an image in which the inventory status of the article is captured) acquired as inventory information of the article by the inventory information acquisition unit 16a to detect the quantity of the article. Then, it is determined whether or not the detected quantity of articles is equal to or less than a predetermined numerical value.

  More specifically, an image authentication process is performed on the captured image (input image) obtained by capturing the stock status of the article “beer” in the refrigerator 20 and the reference image (reference image) of the article “beer”. It is detected how many articles “beer” are stored, and if the number of detected articles “beer” is less than the minimum reference value “6”, it is determined that the inventory is insufficient, and the minimum reference value is reached. If it is “6” or more, it is determined that there is a stock.

  Thus, based on the inventory information of the article, it is determined whether or not the quantity of the article is equal to or less than a predetermined numerical value. When it is determined that the quantity of the article is equal to or smaller than the predetermined numerical value, By setting a route that uses the replenishable guidance target as the destination of the host vehicle, it is possible to determine whether there is inventory according to the standard of the amount of inventory required by the user, and to determine that the user should replenish. When the inventory status is reached, it is possible to guide the route to a guidance target that can be replenished with an out-of-stock item.

  The route setting unit 16c is a processing unit that, when the stock determination unit 16b determines that the inventory of the article is insufficient, sets a route with the guidance target that can be replenished with the article as the destination of the host vehicle. . Specifically, when it is determined that the number of articles “beer” in the refrigerator 20 is less than the minimum reference value “6” by the inventory determination unit 16b, A guidance object that satisfies the selection conditions stored in the selection condition storage table 15b is extracted, and a route is set with the extracted guidance object as the destination of the host vehicle.

  More specifically, the route setting unit 16c searches for stores that can purchase an out-of-stock item “beer” from the store information registered in the map information storage unit 15a. By searching for stores where the item “beer” can be purchased, a list of guidance targets that can be replenished with the item “beer” that is out of stock is listed.

  The route setting unit 16c then satisfies the selection conditions “rule 1” and / or “rule 2” stored in the selection condition storage table 15b among the guidance objects that can be replenished with the item “beer” that is out of stock. To extract. Specifically, a guidance target (that is, a store such as a convenience store, a supermarket, or a department store) that can be replenished with an out-of-stock item “beer” exists on the route from the current position of the vehicle 3 to the location of the refrigerator 20. When the selection condition “Rule 1” is satisfied, the selection condition “Rule” that the guidance target that can be replenished with the item “beer” that is out of stock exists within a predetermined distance (for example, “1 km”) from the location of the refrigerator 20. If “2” is satisfied, a guidance target is extracted as a destination candidate.

  In this way, among the guidance targets that can be replenished with articles, a guidance target that exists on the route from the host vehicle to the point where the accommodation space exists is selected, and the selected guidance target is set as the destination of the host vehicle. By setting the route, it is possible to guide the route to the guidance target that can be replenished without going around the out-of-stock item.

  Further, among the guidance targets that can be replenished with articles, a guidance target that is within a predetermined distance from the point where the accommodation space exists is selected, and a route is set with the selected guidance target as the destination of the host vehicle. This makes it possible to replenish out-of-stock items at a point close to the location of the storage space and suppress a decrease in the freshness of the items.

  Note that the route setting unit 16c performs a route setting process in which, when the stock determination unit 16b newly determines that the stock of the article is not insufficient, the guidance target capable of replenishing the article is the destination of the host vehicle. Cancel. As described above, the reason for canceling the “route setting process” is that even if a situation in which the inventory of goods is insufficient occurs partially, if the goods are replenished by another person, This is to prevent a situation in which the articles are replenished redundantly by continuing this “route setting process”.

  The inventory information notification unit 16 d is a processing unit that notifies the inventory information of the articles received from the article monitoring device 30. For example, as illustrated in FIG. 5, when the inventory determination unit 16 b determines that the inventory of the article is insufficient, the touch panel 11 indicates that the inventory of the article is insufficient (the article needs to be replenished). In addition to displaying, it confirms and displays that the route guidance is to be performed on the guidance target that can be replenished with the out-of-stock items. At this time, a voice notification (in this case, a shortage of inventory) is also performed in the same manner.

  Furthermore, when the stock information notifying unit 16d accepts pressing of the “confirm with image” button on the confirmation display screen 200, the stock status of the article “beer” in the refrigerator 20 is imaged as specific stock information. The captured image is notified. In general, screen notification and audio output are used in combination for notification to the driver. However, it is not preferable to watch the display while driving the vehicle. good.

  In this way, by notifying the inventory information of articles received from the article monitoring device 30, it is possible to allow the user to accurately grasp the inventory status of articles.

(Processing procedures)
Next, procedures of various processes of the navigation system according to the first embodiment will be described. FIG. 6 is a flowchart illustrating the procedure of the route setting process according to the first embodiment. This “route setting process” is performed every predetermined monitoring time (for example, “1 hour”) when the navigation system 1 is activated. Here, an example of managing inventory information of the article “beer” stored in the refrigerator 20 will be described.

  As shown in the figure, when a predetermined monitoring time “1 hour” has elapsed since the previous inventory information acquisition request for an article was made (Yes in step S601), the inventory information acquisition unit 16a displays the inventory information of the article. An acquisition request is transmitted to the article monitoring apparatus 30 (step S602).

  Subsequently, the article monitoring apparatus 30 receives a stock information acquisition request for the article (step S603). In response to this, the control unit 34 reads the image data stored by the image holding unit 35 (step S604), and transmits the read image data to the inventory information acquisition unit 16a as the inventory information of the article “beer”. (Step S605).

  The inventory information acquisition unit 16a in the navigation device 10 receives the image data as the inventory information of the article from the article monitoring device 30 (step S606), and the inventory determination unit 16b uses the inventory information acquisition unit 16a to store the inventory information of the article. Image recognition processing is performed on the image data of the captured image (image in which the inventory status of the article “beer” in the refrigerator 20 is captured) is detected as a quantity (step S607). It is determined whether or not the detected quantity of the article “beer” is equal to or smaller than a predetermined numerical value (that is, whether or not it is less than the minimum reference value “6”) (step S608).

  Here, when the number of articles “beer” is equal to or less than a predetermined value (that is, when the number is less than the minimum reference value “6”) (Yes at Step S608), the route setting unit 16c is configured to store the map information storage unit 15a. Stores that can purchase the item “beer” out of stock are searched for and read from the store information registered in (Step S609).

  The route setting unit 16c then satisfies the selection conditions “rule 1” and / or “rule 2” stored in the selection condition storage table 15b among the guidance objects that can be replenished with the item “beer” that is out of stock. Is extracted (step S610).

  After that, the stock information notifying unit 16d displays that the stock of the goods is insufficient (that the goods need to be replenished), and that the touch panel 11 informs the route guidance to a guidance target that can replenish the out-of-stock goods. A confirmation display is displayed (step S611).

  Finally, when the update of the route setting from the guidance target in the current route setting to the guidance target capable of replenishing out-of-stock items or the update from the route setting “OFF” is accepted (Yes in step S612), the route setting unit 16c performs the route setting which makes the extracted guidance object the destination of the own vehicle (step S613).

  As described above, according to the navigation system 1 according to the first embodiment, when an article needs to be replenished in conjunction with the notification of the inventory information of the article by the article monitoring device 30, the guidance that can replenish the article is provided. Since the route setting with the target as the destination of the host vehicle is performed, it is possible to guide the route to the guidance target capable of replenishing an out-of-stock item without impairing the convenience of the user.
