The predetermined time interval is, for example, one hour, half a day, or one day, and may be set by the user using the communication terminal 3 or set by an employee of a company providing products using the computer 5. it can.

[Configuration of communication terminal 3]
FIG. 4 is a diagram showing the configuration of the communication terminal 3. The communication terminal 3 includes a first communication unit 31, a second communication unit 32, a display unit 33, a storage unit 34, and a control unit 35.

  The first communication unit 31 is, for example, a communication module for Bluetooth, and transmits and receives data to and from the measuring device 2. The first communication unit 31 receives data of the weight measured by the measuring device 2. In addition, the first communication unit 31 transmits, to the measurement device 2, the set value of the measurement time interval used to control the measurement timing of the measurement device 2. The first communication unit 31 may transmit, to the measuring device 2, a set value of timing for transmitting data of the weight measured by the measuring device 2 to the communication terminal 3.

  The second communication unit 32 is, for example, a communication module for LTE (Long Term Evolution), and transmits and receives data to and from the order management device 4. The second communication unit 32 transmits the measurement data of the weight received by the first communication unit 31 from the measurement device 2 to the order management device 4 in association with the identification information of the communication terminal 3. The second communication unit 32 may transmit, instead of the identification information of the communication terminal 3, user IDs assigned to a plurality of users who use the product at the user home. The second communication unit 32 also receives the instruction data transmitted by the order management device 4.

[Configuration of Order Management Device 4]
FIG. 5 is a diagram showing the configuration of the order management device 4. The order management device 4 includes a communication unit 41, a storage unit 42, and a control unit 43. The communication unit 41 is a communication interface for communicating with the communication terminal 3 via the network N, and includes, for example, a LAN (Local Area Network).

  The storage unit 42 includes a ROM and a RAM, and stores a program to be executed by the communication unit 41. Further, the storage unit 42 stores the purchase unit amount of the product in association with the user ID. When one user purchases five 10 kg (10 L) water tanks, the storage unit 42 stores 5 × 10 kg as a purchase unit amount associated with the user ID.

  Furthermore, the storage unit 42 stores information on the user. For example, the storage unit 42 stores the identification information of the communication terminal 3 that transmits the weight measured by the measuring device 2 installed in the user's house to the order management device 4 in association with the user ID. By doing this, the weight measured by the measuring device 2 can be transmitted to the order management device 4 as in the case where there are a plurality of families using the communication terminal 3 in the user's home where the measuring device 2 is installed. When a plurality of communication terminals 3 exist, the control unit 43 can specify the user ID based on the identification information of the communication terminals 3.

  In addition, the storage unit 42 stores weight data in association with the time when the weight is measured in the measuring device 2 or the time when weight data is transmitted from the communication terminal 3 for each user ID. The storage unit 42 outputs various data stored therein to the control unit 43 in response to a request from the control unit 43.

  The control unit 43 is, for example, a CPU, and controls each unit of the order management device 4. The control unit 43 functions as an information acquisition unit 431, a weight acquisition unit 432, an inventory amount identification unit 433, and a determination unit 434 by executing the programs stored in the storage unit 42.

  The information acquisition unit 431 acquires information indicating a purchase unit amount. The information acquisition unit 431 acquires, for example, information indicating the purchase unit amount input by the employee in the computer 5 in association with the user ID. The information acquisition unit 431 causes the storage unit 42 to store information indicating the acquired purchase unit amount.

  The weight acquisition unit 432 acquires the weight of the item in use by the user. Specifically, the weight acquiring unit 432 acquires, via the communication unit 41, the network N, and the communication terminal 3, weight data indicating the weight of the product measured at the measurement timing of the predetermined time interval by the measuring device 2. The weight acquisition unit 432 specifies the user ID based on the identification information of the communication terminal 3 that has transmitted the weight data by referring to the storage unit 42. The weight acquisition unit 432 associates the weight data with the user ID, and notifies the stock amount identification unit 433 of it.

  The stock amount specifying unit 433 is based on the purchase unit amount acquired by the information acquiring unit 431 and stored in the storage unit 42 and the weight of the product acquired by the weight acquiring unit 432, the inventory amount of the product at the user home Identify. For example, in response to the weight data and the user ID being acquired from the information acquiring unit 431, the inventory amount specifying unit 433 specifies an inventory amount of goods at a user's home corresponding to the user ID.

  Although the details will be described later, the stock amount specifying unit 433 stocks the stock quantity, which is the number of items held by the user, based on the relationship between the purchase unit amount and the weight of the item acquired by the weight acquisition unit 432. Identified as a quantity. Specifically, the inventory amount specifying unit 433 specifies that the purchase unit amount is the initial commodity amount of water at the user home. Then, the inventory amount specifying unit 433 specifies that the difference value between the initial commodity amount and the cumulative value of the weight of the commodity measured by the measuring device 2 is the latest inventory amount.

  FIG. 6 is a diagram for explaining a method of identifying the stock amount by the stock amount identification unit 433. Here, it is assumed that the product is water, and the initial product amount of water in the user's house is equal to the purchase unit amount (for example, 10 kg × 5). FIG. 6A shows the elapsed time (horizontal axis) from time T0 when the user installed the first first water tank in the water server 1 and the weight (vertical axis) measured by the measuring device 2. It shows the relationship. FIG. 6B shows the time when the weight is measured by the measuring device 2 specified by the stock amount specifying unit 433, the number of items in stock, and the weight measured by the measuring device 2 (hereinafter referred to as measured weight). , Is a table showing the relationship between the inventory amount of goods. The stock quantity is the number of products remaining in the user's house, including the products installed in the water server 1.

  The stock amount specifying unit 433 specifies the stock amount by (the number of items in stock of the product−1) × the weight of one product + the measured weight. For example, at time T0, the measured weight is 10 kg and the stock quantity is five. Therefore, the stock amount identification unit 433 calculates the stock amount at time T0 as (5 pieces / piece) × 10.0 kg + 10.0 kg = 50.0 kg. Since the measured weight at time T1 is 5.0 kg, the stock amount specifying unit 433 specifies the stock amount at time T1 as 45.0 kg.

  The inventory amount specifying unit 433 determines that the number of items in stock does not change while the weight of the product is decreasing, and the product to be measured by the measuring device 2 is replaced when the weight of the product increases. judge. When it is determined that the product has been replaced, the inventory amount specifying unit 433 specifies the latest stock number by subtracting 1 from the stock number before determining that the product has been replaced. Specifically, when the measured weight increases, the stock amount identification unit 433 determines that the product installed in the water server 1 is empty and a new product is installed, and the number of stocks decreased by one. It shall be. Then, the stock amount specifying unit 433 calculates the stock amount based on the reduced number of stocks.

  In the case of the example shown in FIG. 6, the measured weight has increased from 1.0 kg to 9.0 kg between the time T2 and the time T3, and it is considered that the goods were replaced during this time. Therefore, the inventory amount specifying unit 433 specifies that the number of items in stock for the product has become four. Then, the stock amount identification unit 433 calculates the stock amount of the product at time T3 as (4 pieces / piece) × 10.0 kg + 9.0 kg = 39.0 kg.

  When the weight acquired by the weight acquisition unit 432 increases, the inventory amount specifying unit 433 transmits information for confirming that the product has been replaced to the communication terminal 3, and the communication terminal 3 replaces the product. It may be determined that the product has been replaced on the condition that an affirmative response is received. Further, the inventory amount specifying unit 433 determines that the product has been replaced on the condition that the increase amount of the weight acquired by the weight acquisition unit 432 is equal to or more than the amount within the predetermined range from the weight in the initial state of the product. May be By doing this, it is possible to prevent the inventory amount specifying unit 433 from erroneously determining that the product has been replaced when, for example, the weight is increased due to the non-product being placed on the water server 1.

  The stock amount specifying unit 433 specifies that the stock number has increased to the purchase unit number when the weight of the product increases with the number of stocks being one. As described later, the stock amount specifying unit 433 updates the number obtained by adding the number of purchased units to the number of stock at that time after the period required for delivery has passed since the product of the number of purchased units has been shipped to the user. It is good also as a stock quantity of.

  The determination unit 434 determines, based on the stock amount specified by the stock amount specifying unit 433, a recommended order timing that is a timing to recommend an order for a product of the purchase unit amount. The determination unit 434 determines, for example, the order timing recommended for the user corresponding to the user ID, based on the stock amount associated with the user ID. For example, the determining unit 434 determines the recommended ordering timing based on the timing when the number of stocks becomes equal to or less than the predetermined number associated with the user ID, and communicates that the recommended ordering timing is through the communication unit 41. The terminal 3 is notified. When the determination unit 434 receives a message requesting an order from the communication terminal 3, the determination unit 434 transmits information requesting an order to the computer 5 in association with the user ID.

  If the weight acquiring unit 432 has not acquired new weight data for a predetermined period since the weight acquiring unit 432 has acquired weight data from the communication terminal 3, the determining unit 434 may notify the communication terminal 3 to that effect. . For example, when the predetermined time has elapsed from the previous reception time of weight data, or when the predetermined time has elapsed after the number of stocks has become equal to or smaller than the predetermined number, the determination unit 434 sends the weight to the communication terminal 3. Send a message indicating that the data could not be obtained. In this case, the determination unit 434 preferably displays a button for ordering as well as displaying that there is a possibility that the number of stocks is decreasing. By doing this, since the user of the communication terminal 3 can place an order while the user is not at home, it is possible to prevent the loss of stock while leaving a family and being absent on a business trip or a trip.

  In addition, when transmitting a message indicating that weight data can not be acquired to the communication terminal 3, the determination unit 434 turns on the Bluetooth function to enable communication with the measuring device 2. You may send a message that recommends that. By doing this, it is possible to prevent the continuation of a state in which weight data can not be received due to the Bluetooth function being off in the communication terminal 3.

  FIG. 7 is a diagram for describing a method in which the determination unit 434 determines a recommended order timing. FIG. 7A shows that the stock amount specifying unit 433 specified that the number of stocks decreased from 2 pieces to 1 piece due to the increase in measured weight between time T22 and time T23. . The determination unit 434 determines time T23, which is the timing at which the inventory quantity has become one, as the recommended order placement timing.

  When the determination unit 434 notifies the computer 5 that it is the order placement timing, the product is shipped, and for example, the product arrives at the user's home at time T25. At this point, although the number of items in stock at the user's house is 6, the stock amount specifying unit 433 does not recognize that the product has been replaced, so the number of stocks specified by the stock amount specifying unit 433 is One state is maintained.

  As illustrated in FIG. 7B, the determination unit 434 determines based on the timing when the number of items in stock is less than or equal to a predetermined number and the weight of the item acquired by the weight acquisition unit 432 is less than or equal to the predetermined weight. The order timing may be determined. FIG. 7B shows that the determination unit 434 determines the recommended order timing as the time T26 when the number of items in stock is 1 and the measured weight is 5 kg or less.

  The determination unit 434 may determine the recommended order timing further based on the delivery period, which is a period required from the shipment of the product to the receipt by the user. For example, the determination unit 434 refers to the delivery period stored in the storage unit 42 in association with the user ID, and the longer the delivery period, the larger the threshold value of the inventory amount determined to be the recommended order timing. Determine the recommended order timing when there is a large amount.

  The determination unit 434 estimates a consumption period which is a period required for consumption of one product based on the change history pattern of measured weights in the past, and determines a recommended order timing based on the estimated consumption period. May be The determination unit 434 is specified based on the time when the weight stored in the storage unit 42 in association with the user ID is measured and the weight as shown in FIGS. 6 and 7. The relationship is used to estimate the consumption period. The determination unit 434 estimates, for example, the maximum value or the average value of the periods required for consumption of one product in a predetermined period (for example, the past three months) as the consumption period.

  The determination unit 434 specifies the amount of goods consumed in the period corresponding to the delivery period based on the estimated consumption period. For example, if the period for consuming 10 kg of water is 5 days and the delivery period is 2 days, the determination unit 434 determines that the amount of goods consumed during the period corresponding to the delivery period is 10 kg × 2 × 5 = 4 kg. Identify as Then, the determination unit 434 determines the recommended order timing as the timing before the timing when the stock amount becomes equal to or less than the amount consumed by the product during the period corresponding to the delivery period. By doing this, the order management device 4 can prevent the stock of the product from running out while preventing the stock of the excessive product from remaining in the user's house.

  The determination unit 434 may specify the consumption period for each month or season. For example, the determination unit 434 calculates a first consumption period in a first period when the average temperature is higher than a predetermined temperature and a second consumption period in a second period when the average temperature is lower than the predetermined temperature, and determines the order timing. The recommended order timing is determined using the consumption period corresponding to the time to which the time of day belongs. By doing this, the determination unit 434 may run out of stock while preventing the excess stock of the product from remaining in the user's home, even when the consumption of the product varies depending on the season. It is possible to set the recommended order timing as the appropriate timing that can prevent the

  Although FIG. 7 illustrates the case where the inventory amount identification unit 433 determines that the inventory quantity has increased at the timing when the weight measured by the measuring device 2 increases after the product arrives at the user, the inventory amount identification unit In 433, the information acquiring unit 431 may increase the number of stocks at the timing when the notification that the product has arrived at the user's home has been received from the sales company of the product. By doing this, the determination unit 434 can determine the recommended order timing based on the stock quantity grasped in real time, so that the accuracy of the determination can be improved.

  Further, the determination unit 434 may transmit the image shown in FIG. 7A or FIG. 7B to the communication terminal 3, and the user may display the image by application software of the communication terminal 3. By doing this, the user can confirm the consumption condition of the product, the ordering timing, and the delivery timing, so that the user can feel secure.

[Communication sequence in order management system S]
FIG. 8 is a diagram showing a communication sequence among the measuring device 2, the communication terminal 3 and the order management device 4 in the order management system S. The communication sequence shown in FIG. 8 starts from the process (S11) of determining whether the measuring device 2 is the measurement timing.

  When the control unit 25 of the measuring device 2 determines that the time coincides with the set value of the measurement timing in step S11 (S11), the control unit 25 causes the weight sensor 21 to measure the weight and acquires weight data (S12) . The control unit 25 temporarily stores the acquired weight data in the storage unit 24.

  When acquiring the measurement data, the control unit 25 controls the communication unit 23 to establish a Bluetooth connection with the communication terminal 3. When the communication unit 23 transmits an advertisement and receives the advertisement from the first communication unit 31 of the communication terminal 3, the communication unit 23 transmits a connection request to the communication unit 23 and establishes a connection.

  When the connection with the communication terminal 3 is established, the control unit 25 reads the weight data stored in the storage unit 24, and transmits the measurement result including the weight data to the communication terminal 3 through the communication unit 23. To do (S13). The communication terminal 3 transmits the measurement result received by the first communication unit 31 from the measurement device 2 to the order management device 4 by the second communication unit 32. When receiving the measurement result, the weight acquisition unit 432 of the order management device 4 acquires weight data included in the measurement result and stores the weight data in the storage unit 42 (S14).

[Operation Flowchart of Order Management Device 4]
FIG. 9 is an operation flowchart of the order management device 4. The flowchart illustrated in FIG. 9 starts with the process in which the stock amount identification unit 433 identifies the initial commodity amount (S21). For example, the inventory amount specifying unit 433 specifies a purchase unit amount as an initial commodity amount. Subsequently, the weight acquisition unit 432 acquires weight data included in the measurement result transmitted from the communication terminal 3 (S22).

  The inventory amount specifying unit 433 calculates the latest inventory amount based on the initial commodity amount identified in step S21 and the weight indicated by the weight data acquired in step S22 (S23). Subsequently, the determination unit 434 determines whether the stock amount calculated in step S23 is equal to or less than a threshold for determining the recommended order timing (S24). If the determination unit 434 determines that the inventory amount is larger than the threshold, the control unit 43 returns the process to step S22. If the determination unit 434 determines that the stock quantity is equal to or less than the threshold, the determination unit 434 determines a recommended order timing (S25). For example, after determining that the stock amount is equal to or less than the threshold value, the determination unit 434 determines the date and time within a predetermined period as the recommended order timing.

  When determining the recommended order timing, the determination unit 434 transmits a message for recommending the order to the communication terminal 3 (S26). The determination unit 434 monitors whether or not to receive a message instructing ordering from the communication terminal 3 within a predetermined period after transmitting the message (S27). When the determining unit 434 receives the message instructing ordering within the predetermined period, the deciding unit 434 notifies the computer 5 of the ordering timing to execute the ordering process (S28). It should be noted that instead of ordering via determination unit 434, a link to the ordering site is included in the message sent to communication terminal 3, and the product is ordered by the user clicking on the ordering site link You may do so.

  In step S27, when the determination unit 434 does not receive the message instructing ordering within the predetermined period, the control unit 43 returns the process to step S22. In step S27, when the determination unit 434 does not receive the message instructing ordering within the predetermined period, the determination unit 434 may retransmit the message recommending the order a predetermined number of times.

[Modification 1]
In the above description, although the inventory amount specifying unit 433 sets the purchase unit amount as the initial commodity amount, it is conceivable that the user installs the measuring device 2 while starting to use the purchased commodity. In such a case, if the purchase unit amount is set as the initial commodity amount, the inventory amount specifying unit 433 can not accurately specify the inventory amount. Therefore, the information acquisition unit 431 acquires an initial commodity amount, which is the amount of commodities held by the user at the initial time, and the inventory amount specifying unit 433 acquires the initial commodity amount acquired by the information acquisition unit 431, and information acquisition The stock amount may be specified based on an amount obtained by adding the purchase unit amount purchased by the user after the unit 431 acquires the initial item amount.

  For example, when weight data initially acquired by the weight acquisition unit 432 is smaller than the weight of the unused item by a predetermined amount or more, the information acquisition unit 431 causes the communication terminal 3 to store the number of items in stock at the user's home. Send screen data for input. The communication terminal 3 displays a screen for inputting the stock quantity of goods, and the information acquisition unit 431 acquires the stock quantity input in the communication terminal 3 as the initial goods quantity. The stock amount identification unit 433 identifies the initial commodity amount based on the initial number of items acquired by the information acquisition unit 431 and the latest weight data acquired from the weight acquisition unit 432. For example, when the number of items in stock at the user's house is 3 and the weight measured by the measuring device 2 is 5 kg, the inventory amount specifying unit 433 is (3-1) x 10 kg + 5 kg = 25 kg initially It can be specified that it is a commodity amount.

  As described above, when the information acquiring unit 431 determines that the input of the initial commodity amount is necessary based on the measurement result of the weight in the measuring device 2, the screen for inputting the stock quantity of the commodity as the communication terminal By displaying in 3, it is possible to reduce the probability that the user forgets to enter the number of items in stock. Therefore, even when the user starts using the measuring device 2 while using the product, the stock amount specifying unit 433 can specify the stock number with high accuracy.

[Modification 2]
In the above description, the inventory quantity specifying unit 433 makes the inventory quantity of goods equal to the purchase unit quantity because the weight acquired from the measuring apparatus 2 increases with the number of goods in stock at the user's house being one. However, the inventory amount specifying unit 433 may specify that the number of items in stock is equal to the number of purchase units by another method. For example, the inventory amount specifying unit 433 adds the purchase unit number to the latest inventory number when the determination unit 434 transmits the order instruction to the computer 5 and receives notification from the computer 5 that the order has been completed. Inventory may be updated. In addition, the inventory amount specifying unit 433 adds the number of purchased units to the latest number of inventory when notified that the product of the number of purchased units has arrived from the communication terminal 3 or another device (for example, the computer of the delivery company). Stock may be updated.

[Modification 3]
The period from when the user decides to order a product to when the product arrives at the user may vary depending on the date and time when the product is shipped and the day of the week. For example, if the user decides to order a product on a Saturday morning, there will be a two day delay by Monday morning when the employees of the company using the order management device 4 can process the shipment of the product. .

  Therefore, the stock amount specifying unit 433 may specify the stock amount in association with the date or day corresponding to the measurement timing, and the determining unit 434 may determine the recommended order timing based on the stock amount and the date or day. . For example, the determination unit 434 increases the threshold value of the inventory amount for determining the recommended order timing when the predetermined number of days or hours before the weekend or holiday is reached, and allows the user to place an order at an earlier timing than usual. Ensure that the goods will be shipped by Friday.

  The determination unit 434 may determine the threshold value of the stock amount to be determined as the recommended order timing, based on the consumption period of the product at the user home. For example, the determination unit 434 calculates an amount estimated to be consumed during the weekend or holiday based on the consumption period, and adds the calculated amount to the normal threshold to the weekend or holiday The threshold used up to a predetermined number of days or hours. By doing this, it becomes possible for the company providing the product to place an order so that the inventory at the user's home does not run out even if the product is consumed during the weekend or holiday.

[Modification 4]
Although the case where the capacity of the goods delivered to a user's house was one type was illustrated in the above explanation, there may be a plurality of kinds of goods (for example, 10L and 5L) from which a capacity differs. In this case, the order management system S can further enhance the convenience of the user by the following method.

  For example, it is assumed that the recommended consumption period is set for the product. In this case, the inventory amount specifying unit 433 specifies a cycle in which the user consumes one product based on the opening date and time (for example, the date and time when the weight increases). When the consumption cycle specified by the stock amount specifying unit 433 exceeds the recommended consumption time limit, the determining unit 434 transmits, to the communication terminal 3, a message recommending a product with a small capacity per piece. The determination unit 434 may transmit, to the communication terminal 3, a message recommending a product with a small capacity per piece when detecting that the consumption pace has become slow based on the history of weight data. By doing this, the user can consume the product within the recommended consumption period.

  In addition, when the weight acquired by the weight acquiring unit 432 increases, the inventory amount specifying unit 433 has a product with a weight larger than the weight after the increase and closest to the weight after the increase among the plurality of products having different capacities. It may be determined that it has been replaced. For example, when the weight data acquired by the weight acquiring unit 432 is 6 kg, the inventory amount specifying unit 433 determines that 10 L of a product with a weight of 10 kg is installed, and when the weight data is 4.5 kg, the weight is It determines that 5 kg of 5 L products have been installed. By doing this, the inventory amount specifying unit 433 can improve the identification accuracy of the inventory amount when there are a plurality of products having different capacities.

[Effect by order management system S]
As described above, in the order management device 4, the stock amount identification unit 433 determines the stock amount of the product based on the purchase unit amount and the weight of the product measured by the measuring device 2 installed at the user's house. Identify. Then, the determination unit 434 determines, based on the stock amount, a recommended ordering timing that is a timing at which the ordering of a product of the purchase unit amount is recommended. By doing this, in the order management system S, even when the user does not set the initial stock amount, it is possible to specify the timing suitable for the order. Therefore, by using the order management system S, the company providing the product can allow the user to order the product before the product inventory at the user home runs out, so the product runs out at the user home Can prevent the occurrence of the

  Further, in the order management system S, when the user installs a new product in the water server 1, the user does not need to input the number of stock of the product, and the order management device 4 estimates the number of stock. Therefore, it is possible to prevent the order management device 4 from erroneously recognizing the stock quantity by the user forgetting to input the stock quantity or incorrect input of the stock quantity.

  Further, in the order management system S, the determination unit 434 determines the recommended order timing based on the timing when the number of stocks becomes equal to or less than the predetermined number, and communicates via the communication unit 41 that the recommended order timing is available. The terminal 3 is notified. Then, when the communication terminal 3 receives from the user an operation for instructing an order at the notified recommended order timing, the communication terminal 3 transmits, to the order management device 4, order information indicating that the purchase unit water is ordered. With such a configuration, the user of the communication terminal 3 can determine whether the product is shipped or not, so that the product provider can ship the product at an appropriate timing for the user.

  As mentioned above, although the present invention was explained using an embodiment, the technical scope of the present invention is not limited to the range given in the above-mentioned embodiment, and various modification and change are possible within the range of the gist. is there. For example, a specific embodiment of device distribution and integration is not limited to the above embodiment, and all or a part thereof may be functionally or physically distributed and integrated in any unit. Can. In addition, new embodiments produced by any combination of a plurality of embodiments are also included in the embodiments of the present invention. The effects of the new embodiment generated by the combination combine the effects of the original embodiment.

  For example, although the case where goods are water was illustrated in the above-mentioned explanation, the present invention is applicable to arbitrary goods in which weight changes by user's consumption. For example, even when the product is rice and the measuring device 2 is provided in rice bran, it is apparent that the application of the present invention produces the same effect as the case where the product is water.
