[Operation of order system 100]
Next, the operation of the order system 100 will be described.
When the customer visits the store, the store clerk determines the table to be guided, and inputs the table ID and the number of store visitors through the operation unit 43 of the master terminal 4.
In the master terminal 4, when the table ID and the number of visitors are input by the operation unit 43, the control unit 41 acquires the store visit time by the time measuring unit 46, and uses the input table ID, number of people, and store visit date and time for the store. Stored in the order information storage unit 422. Then, the control unit 41 instructs the digital signage device 2 corresponding to the input table ID to start the order process through the communication unit 45.
In the digital signage apparatus 2, when the communication unit 26 instructs the master terminal 4 to start order processing, the order processing is started.

  FIG. 10 shows a flowchart of order processing executed in the digital signage apparatus 2. The order process is executed in cooperation with the control unit 23 and the program stored in the program storage unit 251.

First, the controller 23 causes the projector 24 to display a menu screen on the image forming unit 27 (step S1).
Next, the control unit 23 acquires the beverage-specific threshold table stored in the beverage-specific threshold storage unit 523 from the management server 5 via the master terminal 4 by the communication unit 26 and stores the acquired beverage-specific threshold value table 256 in the beverage-specific threshold storage unit 256 ( Step S2).

Next, the control unit 23 determines whether pairing information has been received from the coaster 1 by the wireless communication unit 30 (step S3).
Here, when the customer is seated at the table, the store clerk guides the customer to hold the member card 6 over the coaster 1 of the seated seat and perform pairing. When the first wireless communication unit 15 detects the member card 6, the control unit 11 of the coaster 1 reads the customer ID from the member card 6 and stores it in the customer ID storage unit 123. Further, the control unit 11 associates the read customer ID with its own coaster ID and transmits it as pairing information to the digital signage device 2 on the table by the second wireless communication unit 16.

When it is determined that the pairing information has been received by the wireless communication unit 30 (step S3; YES), the control unit 23 stores the received pairing information in the pairing information storage unit 253 (step S4), and the received pair The order history corresponding to the customer ID of the ring information is acquired from the management server 5 via the master terminal 4 by the communication unit 26 and stored in the order history storage unit 254 (step S5), and the process proceeds to step S6.
In step S5, specifically, the control unit 23 transmits the customer ID of the received pairing information to the management server 5 through the communication unit 26, and makes an order history acquisition request. In the management server 5, when the control unit 51 receives a customer ID and order history acquisition request from the digital signage device 2 through the communication unit 55, whether or not the received order history of the customer ID exists in the order history storage unit 522. If it exists, the order history corresponding to the customer ID is read out and transmitted to the digital signage device 2 by the communication unit 55.
As described above, in the digital signage device 2, the control unit 23 can identify the customer seated in the seat corresponding to each coaster 1 based on the pairing information, and can acquire the order history of the customer. .

  When it is determined that the pairing information has not been received by the wireless communication unit 30 (step S3; NO), the control unit 23 proceeds to step S6.

In step S6, the control unit 23 determines whether or not an order is input by the operation unit 32 (step S6).
Here, the order can be input from the menu screen. For example, when the cross button 32a of the operation unit 32 is operated to move the cursor to a desired menu displayed on the menu screen and the determination button 32b is pressed while the menu is selected, the order screen of the selected menu is displayed. . On the order screen, for example, the name and amount of the selected menu are displayed, and the seating chart in the table is displayed. The voice output unit 33 outputs a message such as “To place an order, specify the seat of the orderer from the seating chart and press the enter button”. After confirming the menu and amount to be ordered, the orderer operates the cross key 32a of the operation unit 32 to designate the seat on which he / she is seated from the seating chart and presses the enter button 32b to place the order. Can be entered.

If it is determined that the order has been input (step S6; YES), the control unit 23 refers to the seat / coaster correspondence storage unit 252 to acquire the coaster ID corresponding to the seat designated from the order screen and input it. The order contents and the current time (order time) are stored in the table order information storage unit 255 in association with the coaster ID (step S7). Moreover, the control part 23 acquires customer ID corresponding to the acquired coaster ID with reference to the pairing information storage part 253, and matches table ID, acquired coaster ID, customer ID, order time, and order content. The order information is transmitted to the master terminal 4 by the communication unit 26 (step S8), and the process proceeds to step S9. The control unit 41 of the master terminal 4 stores the information received from the digital signage device 2 by the communication unit 45 in the store order information storage unit 422.
On the other hand, when determining that no order has been input (step S6; NO), the control unit 23 proceeds to step S9.

In step S9, the control unit 23 determines whether or not the detection result from the coaster 1 is received by the wireless communication unit 30 (step S9).
When it is determined that the detection result from the coaster 1 has not been received by the wireless communication unit 30 (step S9; NO), the control unit 23 proceeds to step S15.

  When it is determined that the detection result from the coaster 1 is received by the wireless communication unit 30 (step S9; YES), the control unit 23 refers to the table order information storage unit 255 and receives the coaster from the coaster 1 together with the detection result. The latest order content corresponding to the ID is specified (step S10), and a threshold value corresponding to the beverage of the specified order content is acquired with reference to the beverage-specific threshold storage unit 256 (step S11). Then, the control unit 23 determines whether any of the received remaining amount or temperature exceeds (below) the threshold value (step S12). When it is determined that none of the received remaining amount or temperature exceeds the threshold value (is not below) (step S12; NO), the control unit 23 proceeds to step S15.

  When it is determined that either the remaining amount or temperature received has exceeded (below) the threshold (step S12; YES), the control unit 23 is seated in the seat corresponding to the coaster 1 that is the transmission source of the detection result. It is determined that it is the order timing of the customer (step S13), and menu presentation processing is executed (step S14).

  FIG. 11 shows a flowchart of the menu presentation process executed in step S14 of FIG. The menu presentation process is executed in cooperation with the control unit 23 and the program stored in the program storage unit 251.

First, the control unit 23 searches whether the coaster ID received together with the detection result from the coaster 1 exists in the pairing information storage unit 253, and based on the search result, the coaster 1 that is the transmission source of the detection result is It is determined whether it is paired with the membership card 6 (step S131).
When it is determined that the coaster 1 as a transmission source of the detection result is paired with the member card 6 (step S131; YES), the control unit 23 displays the order history of the customer ID associated with the received coaster ID. A menu (recommended menu) to be acquired from the order history storage unit 254 and presented to the customer with the customer ID is determined based on the acquired order history (step S132), and the process proceeds to step S134.

  As a menu determination method in step S132, for example, referring to the time zone and order order of the past order included in the acquired order history, the order tendency of the customer is analyzed, and the current time zone and the next order are analyzed. The menu having the highest probability of being ordered in the order is determined as the recommended menu. For example, in the case of a customer whose first three orders are always beer and then go to hot coffee, the first three orders are determined as a menu that recommends beer and then hot drink. The recommended menu may be determined in consideration of the season. Alternatively, the menu with the highest order frequency may be specified based on the acquired order history, and the menu with the highest order frequency may be determined as the recommended menu.

On the other hand, when it is determined that the coaster 1 as the transmission source of the detection result is not paired with the member card 6 (step S131; NO), the control unit 23 determines a recommended menu using a predetermined algorithm (step S133), The process proceeds to step S134.
For example, referring to the table order information storage unit 255, a menu ordered by a person on the same table is determined as a recommended menu. In addition, a menu with high sales in a store, a menu for which sales are desired to increase in a store, and the like may be determined as recommended menus.

  In step S134, the control unit 23 reads the determined recommended menu price from the storage unit 25, and determines whether the recommended menu is charged (step S134). Here, the free menu is, for example, water. In the present embodiment, water can be ordered from the menu screen.

When the recommended menu is free (step S134; NO), the control unit 23 proceeds to step S137.
When the recommended menu is charged (step S134; YES), the control unit 23 causes the image forming unit 27 and / or the audio output unit 33 to present the menu determined in step S132 or step S133 (step S135). For example, an image of a person or character whose line of sight is directed toward the seat corresponding to the coaster ID is transmitted to the projector 24 and displayed on the image forming unit 27, and “How about Beverage A? The message “Please press the button” is output by the voice output unit 33.

  Next, the control unit 23 determines whether or not the consent button 32c is pressed by the operation unit 32 within a predetermined time (step S136). When it is determined that the consent button 32c is pressed within the predetermined time (step S136; YES), the control unit 23 proceeds to step S137. When determining that the consent button 32c has not been pressed within the predetermined time (step S136; NO), the control unit 23 returns the display of the image forming unit 27 to the menu screen and returns to step S3 of FIG.

In step S137, the control unit 23 stores the menu and the current time determined in step S132 or step S133 in the table order information storage unit 255 as the order contents and the order time in association with the coaster ID of the detection result transmission source. (Step S137). In addition, the control unit 23 determines the table ID, the coaster ID of the detection result transmission source, the customer ID corresponding to the coaster ID (when paired), the determined menu (order contents), and the current time (order time). Are transmitted to the master terminal 4 as order information by the communication unit 26 (step S138). And it transfers to step S15 of FIG.
In the master terminal 4, when order information is received from the digital signage device 2 by the communication unit 45, the control unit 41 stores the received information in the store order information storage unit 422.

In step S15 in FIG. 10, the control unit 23 determines whether or not the communication unit 26 has received an instruction to end order processing from the master terminal 4 (step S15).
Here, when an offer for accounting is made by the customer, the store clerk causes the display unit 44 to display today's order information of the table used by the customer in the master terminal 4 by operating the operation unit 43. Then, accounting is performed based on the displayed information, and accounting registration is performed at the master terminal 4. When the transaction registration is performed, the control unit 41 of the master terminal 4 transmits an order processing end instruction to the digital signage device 2 of the table registered for transaction by the communication unit 45.

When it is determined that the instruction to end the order process from the master terminal 4 has not been received (step S15; NO), the control unit 23 returns to step S3. In addition, when customers exchange seats, it is possible to continue presenting recommended menus according to customers by re-pairing.
When it is determined that an instruction to end order processing from the master terminal 4 has been received (step S15; YES), the control unit 23 performs the pairing information storage unit 253, the order history storage unit 254, and the table order information storage unit 255. The information in the threshold value storage unit 256 for each beverage and the customer ID storage unit 123 of each coaster 1 is reset (step S16), and the order process ends.

  When the transaction registration is completed in the master terminal 4, the control unit 41 stores the customer ID, the visit date / time, the coaster ID, and the order contents of the record in which the customer ID is recorded in the table in which the transaction registration in the store order information storage unit 422 is completed. The order time and the like are associated with each other and transmitted to the management server 5 by the communication unit 45. In the management server 5, the data received from the master terminal 4 by the communication unit 55 is added to the order history storage unit 522 to update the order history storage unit 522.

As described above, according to the ordering system 100, each coaster 1 arranged corresponding to a seat in the table is provided with a remaining beverage container provided based on an order by a customer seated in the corresponding seat. The amount and temperature are detected and transmitted to the digital signage device 2. The control unit 23 of the digital signage device 2 determines the order timing of each customer based on the remaining amount and temperature acquired from each coaster 1, and presents a menu by the image forming unit 27 or the audio output unit 33 at the determined order timing. Let
Therefore, it is possible to present a menu at an optimal order timing that matches the customer's pace and beverage temperature.

  For example, the digital signage device 2 includes a beverage-specific threshold storage unit 256 that stores a remaining amount and a temperature threshold for each beverage type, and the control unit 23 stores the remaining amount and temperature acquired from the coaster 1 and a threshold for each beverage. The order timing is determined based on the comparison result with the threshold value corresponding to the type of beverage stored in the unit 256. Therefore, the menu is presented at the optimal order timing, such as when the remaining amount of the provided beverage is less than the threshold value, or when the temperature of the beverage has cooled below the threshold value (or when it has become slim). It becomes possible to do.

In addition, the digital signage apparatus 2 includes an order history storage unit 254 that stores an order history, and determines a menu to be presented based on the order history of the customer at the order timing.
Accordingly, it is possible to present a menu that matches the customer's order tendency based on the customer's past order history.

For example, the order history storage unit 254 stores at least an ordered menu and an ordered time as the order history, and the control unit 23 refers to the order history of the customer at the order timing, and the customer The menu to be presented is determined based on the time zone ordered in the past and the order ordered.
Therefore, based on the time zone and the order in which the customer ordered in the past, it is possible to determine the menu that presents a beverage with a high probability that the customer will order.

  In addition, for example, by determining as a menu that presents a menu ordered by another customer in the same table as the customer at the order timing, the customer's interest is also attracted to a customer whose order history is not registered. Menu can be presented.

  A customer seated in a seat corresponding to each coaster 1 can be easily identified by holding the member card 6 storing the customer ID over the coaster 1 and causing the coaster 1 to read the customer ID.

  In addition, since the coaster 1 includes the pressure sensor 13 and the temperature sensor 14, the remaining amount of the beverage (remaining amount of the remaining amount) can be obtained using a coaster that is generally placed on the table without placing a special sensor or the like on the table. Change amount) and temperature can be detected. Further, the remaining amount and temperature of the beverage are not limited to the coaster 1, but the table itself may be provided with a sensor or the like, or may be provided in a cup for containing a beverage, or other methods may be used. .

  In addition, the description content in the said embodiment is a suitable example of the digital signage apparatus which concerns on this invention, and is not limited to this.

For example, in the above-described embodiment, the coaster 1 detects the remaining amount of beverage in the placed container, and the digital signage device 2 determines the order timing based on the remaining amount of beverage. However, the order timing may be determined based on how much the beverage is reduced (= change amount of the remaining amount).
For example, in the coaster 1, when the pressure sensor 13 increases from 0 (a beverage provided by an order is placed), the control unit 11 reduces the mass (remaining amount) including the beverage container to 0. The value is stored in the storage unit 12 as a value. Then, when the detection is performed by the pressure sensor 13, the control unit 11 calculates the amount of change in the detected value (the amount of change in the remaining amount) from the decrease degree 0 stored in the storage unit 12. The change amount may be transmitted to the digital signage device 2. In the management server 5, the threshold value of the remaining amount change amount is stored in the beverage-specific threshold storage unit 523 for each beverage type, and the digital signage device 2 determines that the remaining amount change amount exceeds the threshold value. It may be determined as the order timing. Moreover, in each coaster 1, the value at the time of reduction 0 is transmitted to the digital signage device 2, and when sensing is performed, data indicating the remaining amount of beverage is transmitted to the digital signage device 2, The digital signage device 2 may calculate the amount of change in the remaining amount.

  In the above embodiment, the remaining amount (the remaining amount change amount), the comparison between the temperature and the threshold value, and the determination of the order timing are performed by the digital signage device 2, but may be performed by each coaster 1. . For example, in each coaster 1, the control unit 11 acquires information of the beverage-specific threshold storage unit 256 from the digital signage device 2 and stores the information in the storage unit 12. Further, when the output from the pressure sensor 13 suddenly increases from approximately 0 (when a new beverage is placed), the order content is acquired from the digital signage device 2 and stored in the storage unit 12. In each coaster 1, the order timing is determined by comparing the remaining amount (change amount of the remaining amount) and temperature detected by sensing with the threshold value of the beverage type corresponding to the order contents, and the second wireless The communication unit 16 may notify the digital signage device 2.

  In the above embodiment, the customer's order history is acquired in advance from the management server 5 in the digital signage device 2 and the menu to be presented at the order timing in the digital signage device 2 is determined. The customer ID of the customer may be transmitted to the management server 5, and the management server 5 may determine a menu to be presented based on the order history corresponding to the received customer ID.

  Moreover, in the said embodiment, although demonstrated as providing the menu based on order history at the order timing with respect to the customer registered as a member, it is not limited to this. For example, a menu ordered by another customer of the same table may be presented. It is also possible to present store sales, a high menu, or a menu that the store wants to drink (want to eat).

  In the above embodiment, the sensing interval in the coaster 1 is determined in advance. In the digital signage device 2 (or the management server 5), each coaster is controlled by the control unit 23 (control unit 51). It is good also as referring to the corresponding customer's past order history, determining the sensing interval of each coaster based on the customer's past order history, and setting each coaster 1. In this way, sensing can be performed at an interval that matches the pace at which the customer eats and drinks (ordering pace). For example, in the case of a customer with a slow pace of eating and drinking (ordering pace), the sensing interval can be increased. Can contribute to power saving.

In the above embodiment, the order timing is determined using both the remaining amount of beverage and the temperature. However, only one of the remaining amount (change amount of remaining amount) and temperature may be used. Good.
In addition, when the temperature of the beverage falls below a predetermined threshold, the master terminal 4 may be notified to reheat the cooled beverage instead of presenting the menu.
Moreover, in the said embodiment, although the case where the target of the remaining amount (change amount of residual amount) and temperature in the coaster 1 and the target of the menu presented to the customer and the customer was a beverage was described as an example, It may be a dish on a plate).

  Further, the configuration of the order system is not limited to the above embodiment. For example, when there is only one store, the master terminal 4 may have the function of the management server 5. When the store has only one table, the digital signage device 2 may have the functions of the master terminal 4 and the management server 5.

In the above embodiment, the membership card 6 is an IC card. However, the communication terminal storing the customer ID is not limited to the IC card. For example, the communication terminal in which the customer ID is stored may be a customer's smartphone.
Moreover, the member card 6 may be a coaster type, and the function of the coaster 1 may be installed, and the member card 6 and the coaster 1 may be integrated into a my coaster.

  In the above-described embodiment, the case where the image forming unit 27 of the digital signage apparatus 2 is a human type has been described as an example. However, other shapes may be used and the present invention is not limited to this.

  In the above embodiment, the case where the present invention is applied to a digital signage apparatus that displays an image by projecting an image from a projector onto a screen has been described as an example. Even when applied to an information output device including the display device, the same effect can be obtained, and the present invention is not limited to this example.

  In addition, the detailed configuration and detailed operation of the digital signage apparatus and the order system can be changed as appropriate without departing from the spirit of the invention.

Although several embodiments of the present invention have been described, the scope of the present invention is not limited to the above-described embodiments, but includes the scope of the invention described in the claims and equivalents thereof.
