Hereinafter, the store management system, which is an embodiment of the information processing system of the present disclosure, will be described with reference to the drawings.
The communication distance of the IoT tag (an example of a wireless tag) in the present disclosure is only an example and is not limited. The communication distance of the IoT tag can be appropriately changed or adjusted according to the use of the IoT tag.
In the present disclosure, the "seating tool" is equipment provided in a store for a person to sit down, and examples thereof include chairs and sofas. In the following description, the chair is an example of a sitting tool. Further, the seating tool is described as being a chair for one person, but the present invention is not limited to this.

(1) First Embodiment (1-1) System configuration of the store management system of the present embodiment First, the system configuration of the store management system 1 of the present embodiment will be described with reference to FIG. FIG. 1 is a diagram schematically showing a system configuration of the store management system 1 of the present embodiment.
In FIG. 1, the store management system 1 of the present embodiment is implemented in a store that provides food and drink such as a restaurant. A customer application is installed on the customer user terminal 4. By executing the customer application, the customer can order food and drink from the menu displayed on the user terminal 4. Therefore, store employees do not have to come to the customer's location to take orders.

Since the store management system 1 of the present embodiment is configured so that the customer who has ordered food and drink can specify the seating position (position of the seating tool) of the seated chair, the store employee is the customer. Can serve the food and drink ordered by the customer. For example, an IoT tag is attached to the seating surface of each chair in the store in order to specify the seating position. The IoT tag attached to the chair is appropriately referred to as a "chair tag" in the following description.

In the store management system 1 of the present embodiment, the application server 5 (an example of an information processing device) receives an order from a customer, notifies the customer's seating position and the customer's order details to the store terminal 3, and places an order. It is a cloud-type system that prompts stores to serve food and drink and automatically accounts for customers. The application server 5 can provide services to a plurality of stores, but FIG. 1 shows only one store.

The store terminal 3 (an example of a terminal device) is an information processing terminal provided in a store, and examples thereof include, for example, a laptop personal computer, a tablet terminal, and a smartphone. A store application is installed on the store terminal 3. The store application of the store terminal 3 can communicate with the application server 5 via the network NW.
The network NW is not limited, and examples thereof include LAN (Local Area Network), WAN (Wide Area Network), and the Internet.

As will be described in detail later, the chair tag T1 (IoT tag) is, for example, an energy harvesting type communication device that generates electricity based on radio waves in the surrounding environment, and does not have a battery. The chair tag T1 can contain, for example, a sensor that detects changes in weight, movement (motion such as pickup), ambient temperature, and the like. The application server 5 acquires, for example, data detected by the sensor of the chair tag T1 (sensor data), changes in radio waves output from the chair tag T1 (waveform, etc.), and the weight with respect to the chair tag T1 (that is, that is). By detecting (determining) the load on the corresponding chair), the movement of the corresponding chair, the ambient temperature of the corresponding chair, and the like, it is possible to determine whether or not the chair to which the chair tag T1 is attached is seated.

The communication distance of the chair tag T1 is, for example, in the range of 3 to 10 meters. The chair tag T1 is configured to perform low power consumption wireless communication, and examples of communication protocols include Bluetooth Low Energy (registered trademark) (hereinafter, BLE), Bluetooth (registered trademark), and ZigBee (registered trademark). ) Etc. can be mentioned. In the following, a case of performing communication by BLE will be described as an example.
When the chair tag T1 conforms to the BLE standard, it broadcasts an advertising packet (described later) to surrounding BLE terminals. The packet transmitted by the chair tag T1 includes a tag ID (an example of tag identification information) for identifying the tag, sensor data, and the like.

The route when the application server 5 collects the tag ID and the sensor data of each chair tag T1 in the store is not particularly limited. The collection routes include (i) a route via a gateway device and network NW in a store (not shown), (ii) a customer user terminal 4, a route via a gateway device and network NW (not shown), and (iii) a customer user terminal 4. , A route via a wireless communication network and a network NW, etc. are assumed.

(1-2) Configuration of Each Device of the Store Operation System of the Present Embodiment Next, the configuration of each device of the store operation system 1 of the present embodiment will be described with reference to FIGS. 2 to 6.
FIG. 2 is a block diagram showing an internal configuration of each device of the store management system 1 of the present embodiment. FIG. 3 is a diagram showing a configuration of an advertising packet transmitted from the chair tag T1. FIG. 4 is a diagram showing an example of data structure of the store layout database. FIG. 5 is a diagram showing an example of data configuration of an order data set. FIG. 6 is a diagram showing an example of data structure of the settlement database.

Referring to FIG. 2, the chair tag T1 includes, for example, a control unit 11, an antenna 12, a harvesting unit 13, a voltage control unit 14, an RF transceiver 15, and a sensor 16.
Although the overall form of the chair tag T1 is not shown, for example, it is a thin film in which a conductive metal leaf having a predetermined pattern on which the antenna 12 and the sensor 16 are formed and an IC chip connected to the metal leaf are connected. It is a member. A control unit 11, a harvesting unit 13, a voltage control unit 14, and an RF transceiver 15 are mounted in the IC chip.

The control unit 11 has a microprocessor and a memory 111, and controls the entire chair tag T1. The memory 111 is a RAM (Random Access Memory) or a ROM (Read Only Memory), and is a program executed by a microprocessor, a tag ID which is identification information unique to the chair tag T1, and sensor data output by the sensor 16. Etc. are memorized.

The harvesting unit 13 generates energy harvesting based on radio waves in the surrounding environment (for example, radio waves from ambient wireless communication), and stores the electric power obtained by the power generation in the internal energy storage 131. In the present embodiment, the harvesting unit 13 converts, for example, the radio signal received by the antenna 12 into a DC voltage and stores it in the energy storage 131. The energy storage 131 is, for example, a capacitor. In the case of a capacitor, it may be one configured on a semiconductor chip (that is, an on-die type capacitor).

The radio waves used by the harvesting unit 13 for energy harvesting are radio waves of a plurality of different frequency bands in a wide frequency band. For example, radio waves by wireless communication in the frequency band used in mobile communication systems such as so-called 3G to 5G, and frequency bands used in communication standards such as Bluetooth (registered trademark) and Wi-Fi (registered trademark). Radio waves by wireless communication, radio waves by wireless communication in the 2.4 GHz band represented by communication protocols such as ZigBee (registered trademark) and Thread, frequency bands used in RFID (for example, 900 MHz band, 13.56 MHz band) Radio waves and the like by wireless communication can be mentioned.
Radio waves such as those illustrated here are generally applicable in almost every store. Then, the chair tag T1 operates with the electric power obtained by the energy harvesting by the harvesting unit 13 based on the radio waves of the surrounding environment. Therefore, it is not necessary to mount the battery on the chair tag T1, and the system cost can be suppressed. Further, since it is not necessary to mount the battery, it is not necessary to replace the battery, so that there is no problem that the tag ID cannot be acquired even though the tag exists.

The voltage control unit 14 supplies the operating voltage to the control unit 11 and the RF transceiver 15, and monitors the voltage of the energy storage 131, and switches the power mode according to the monitoring result. When the voltage of the energy storage 131 is equal to or less than a predetermined threshold value, the power mode is set to the first mode in which only the minimum circuit is operated. At this time, the control unit 11 and the RF transceiver 15 generate packets and wirelessly described later. No signal is transmitted. When the voltage of the energy storage 131 is charged to a predetermined threshold value or more, the power mode is set to the second mode in which the normal processing routine is executed. At this time, the control unit 11 and the RF transceiver 15 generate packets and transmit radio signals. Various processes including transmission are performed.

Note that the control unit 11 detects the sensor data detected by the sensor 16 when the voltage of the energy storage 131 is charged to a predetermined threshold value or higher even when the power mode is, for example, the first mode. It may be stored in the memory 111 together with the data of. In that case, even if the control unit 11 generates and transmits a packet containing the sensor data and the detection time data stored in the memory 111 when the power mode is switched from the first mode to the second mode. good.

The sensor 16 detects data (that is, sensor data) such as the load applied to the chair tag T1, the movement of the chair tag T1, and the ambient temperature of the chair tag T1. The sensor data is temporarily stored in the memory 111 for inclusion in a packet described later. When the sensor data indicates a change in movement, the sensor data may be a value indicating the degree of movement of the chair tag T1 or may be a binary value indicating whether or not the chair tag T1 has moved.

The control unit 11 generates an advertising packet according to the BLE protocol when the power mode is the second mode.
The advertising packet is a packet transmitted using the advertising channel in order to realize broadcast communication in BLE, and has the packet configuration shown in FIG. Advertising packets are, as appropriate, simply referred to as "packets" below.

In FIG. 3, each of the preamble and the address access has a predetermined fixed value. CRC is a cyclic check code, which is check data calculated by using a predetermined generation polynomial for a packet payload (that is, an advertising channel PDU (protocol data unit)).
The advertising channel PDU (hereinafter, simply referred to as "PDU") consists of a header and a payload, and the payload consists of an ADV address and ADV data. The ADV address is the address of the advertiser (that is, the chair tag T1 which is the subject of notification), but it may be a random value set each time the transmission is performed so as not to specify the source. The ADV data is advertiser data (broadcast data), and in the present embodiment, the tag ID and the sensor data output by the sensor 16 are included.

The control unit 11 preferably encrypts the PDU. The encryption method is not limited, but for example, AES (Advanced Encryption Standard) with a key length of 128 bits can be used.

The RF transceiver 15 performs predetermined digital modulation (for example, GFSK (Gaussian Frequency Shift Keying)) on the transmitted packet (baseband signal) and then performs quadrature modulation to perform a high frequency signal (2.4 GHz in the case of BLE). (Frequency band signal) is sent to the antenna 12.

The antenna 12 includes a transmitting antenna and a power generation antenna. The transmitting antenna transmits a high frequency radio signal (packet) transmitted by the RF transceiver 15. On the other hand, the power generation antenna receives radio waves in the surrounding environment, for example, and functions as a rectenna in cooperation with the harvesting unit 13.

As shown in FIG. 2, the store terminal 3 includes, for example, a control unit 31, a storage 32, an operation input unit 33, a display unit 34, and a communication unit 35.
The control unit 31 is mainly composed of a microprocessor and controls the entire store terminal 3. For example, the control unit 31 loads and executes a store application stored in the storage 32.
The store application acquires various information regarding the customer's order from the application server 5, for example, by communicating with the application server 5. For example, since the store application acquires and displays the customer's seating position and the customer's order details from the application server 5, the store employee can eat and drink without going to the customer's seat to pick up the order. It can be served to customers.
The storage 32 is a storage device such as an SSD (Solid State Drive), and stores various programs executed by the control unit 41 such as the above-mentioned store application.

The operation input unit 33 is an input interface that receives operation inputs from store employees in order to execute various programs, and may be a touch panel input unit provided on the display panel of the display unit 34.
The display unit 34 includes a display panel such as an LCD (Liquid Crystal Panel) and a drive circuit of the display panel, and displays the execution result of the program by the control unit 31.
The communication unit 35 is a communication interface for communicating with the application server 5 via the network NW.

As shown in FIG. 2, the user terminal 4 includes, for example, a control unit 41, a storage 42, an operation input unit 43, a display unit 44, a first communication unit 45, and a second communication unit 46.

The control unit 41 is mainly composed of a microprocessor and controls the entire user terminal 4. For example, the control unit 41 loads and executes a customer application stored in the storage 42.
The customer application, for example, communicates with the application server 5 to perform a process for registering user information in the application server 5 in advance when ordering food and drink in a store. The user information is, for example, a user ID, a terminal ID of the user terminal 4, user account information at the time of settlement (settlement) of purchased products, and the like. The user ID is, for example, unique identification information given to the user when the customer application is installed on the user terminal 4. The terminal ID is, for example, an individual identification number of the user terminal 4, a contractor unique ID, or the like.
The customer application displays a menu of foods and drinks that can be provided by the store on the display unit 44 so that the customer can select foods and drinks (order target).
The storage 42 is a storage device such as an SSD, and stores various programs executed by the control unit 41 such as the above-mentioned customer application.

The operation input unit 43 is an input interface that receives operation input from the user in order to execute various programs, and may be a touch panel input unit provided on the display panel of the display unit 44.
The display unit 44 includes a display panel such as an LCD and a drive circuit of the display panel, and displays the execution result of the program by the control unit 41.

The first communication unit 45, for example, performs wireless communication with an object in a communication range narrower than that of the second communication unit, and is configured to receive, for example, a packet broadcast by the chair tag T1. Further, the first communication unit 45 is configured to emit a beacon signal according to, for example, the BLE protocol. The beacon signal includes a terminal ID that identifies the user terminal 4.

The second communication unit 46 is a communication interface for communicating with the application server 5 via, for example, a wireless communication network and a network NW (not shown).
In the present embodiment, the control unit 41 acquires the tag ID and the sensor data from the chair tag T1 via the first communication unit 45. The control unit 41 further transmits the tag ID and sensor data acquired from the chair tag T1 and its own user ID to the application server 5 via the second communication unit 46.
As described above, the chair tag T1 generates energy based on the radio waves of the surrounding environment, but when the radio waves of the surrounding environment are low, normal operations such as packet generation and wireless signal transmission are not performed. (For example, when the power mode is the first mode). Therefore, if the control unit 41 of the user terminal 4 cannot communicate with the chair tag T1 (for example, cannot receive the advertising packet) continues for a predetermined time or longer, does the first communication unit 45 start wireless transmission? Alternatively, it is preferable to control the first communication unit 45 so as to increase the transmission power of the first communication unit 45. As a result, electric power can be stored because the radio waves in the surrounding environment of the chair tag T1 increase, and wireless communication with the user terminal 4 can be started or resumed.

As shown in FIG. 2, the application server 5 includes, for example, a control unit 51, a storage 52, and a communication unit 53.

The control unit 51 is mainly composed of a microprocessor and controls the entire application server 5.
The storage 52 (an example of a storage unit) is provided with, for example, a large-scale storage device of an HDD, and stores a store layout database (store L / O DB), an order data set (order DS), a settlement database (settlement DB), and the like. do.
The communication unit 53 functions as a communication interface for communicating with the store terminal 3 and the user terminal 4.

The store layout database of FIG. 4 has values of each field of "tag ID" and "chair position information" for one record, and is a database for managing the arrangement of equipment such as chairs in the store. In the example of FIG. 4, one record corresponds to one chair, and the value in the "tag ID" field is the tag ID of the chair tag attached to the chair, and is in the "chair position information" field. Values include "chair position code" and "coordinates". The "chair position code" is a unique code for specifying the position of the chair. The "coordinates" indicate the coordinates corresponding to the chair position code when the origin is a predetermined position on the store floor.

The order data set of FIG. 5 is data for managing customer orders in a store. One row of data in the order dataset corresponds to a customer's order for one food or drink. Specifically, the data in each row of the order dataset includes tag ID, user ID, order data, and order time information for the chair tag. The order data (an example of request data) includes information on an order ID that identifies an order target and a quantity of the order target.
In order to create the data of each row of the order data set, the control unit 51 performs a process of associating the user ID of the customer who placed the order with the seating position of the customer.

In the settlement database of FIG. 6, each record corresponds to one customer (user). The settlement database has, for example, the values of the "user ID", "terminal ID", "order date", "order data", "payment amount", and "account information" fields for each record. The settlement database is a database for managing the order history for pre-registered customers and the settlement of ordered foods and drinks. As described above, the user ID is unique identification information given to the user (customer) in advance. The terminal ID and account information are information acquired for each user from the customer application of the user terminal 4.

The microprocessor of the control unit 51 executes the following processes (i) to (iii), for example, by executing a predetermined program.

(i) Customer Seating Position Identification Process After the customer visits the store, the application server 5 sequentially receives the user ID, tag ID, sensor data, etc. from the customer's user terminal 4, for example. When the customer is seated in a chair in the store, the control unit 51 detects that the customer is seated based on a predetermined change such as sensor data received from the chair tag of the chair in which the customer is seated. Customer seating detection can be performed from various perspectives.
For example, when the sensor data is the data of the temperature sensor, it may be determined that the customer has been seated when the sensor data indicates a temperature rise within a predetermined time due to the customer's body temperature. When the sensor data is the data of the weight sensor, the seating of the customer can be detected when the sensor data indicates an increase in the weight (load) applied to the chair tag due to the weight of the customer. If the sensor data includes both temperature and weight sensor data, then the customer is based on a combination of sensor data (eg, when both temperature and weight data rise and weight detection results above a given value are shown). You may judge that you were seated. Since there is chair movement when seated, if the sensor data also includes chair tag movement data, there is an increase in weight and / or temperature, for example, multiple chair tag movements have been detected. Based on the combination of sensor data, it may be determined that the customer has been seated.
Since the radio waves transmitted by the chair tag are absorbed into the customer's body when the customer is seated, the value of the received signal strength (RSSI (Received Signal Strength Indicator)) when the user terminal 4 receives from the chair tag decreases. .. Therefore, the decrease in RSSI value may be added to the condition for determining that the customer has been seated.

(Ii) Correspondence processing between the customer's seating position and the customer's order contents Since the control unit 51 sequentially receives the user ID, tag ID, sensor data, etc. from the customer's user terminal 4, the control unit 51 is based on, for example, sensor data. When the customer's seating is detected, the tag ID of the chair tag corresponding to the chair seated by the customer is associated with the user ID in the order data set. Since the tag ID of the chair tag and the position information of the chair are associated with each other in the store layout database, the user ID and the position information of the chair are associated with each other.
Further, the control unit 51 receives the user ID and the order data from the customer application, and associates the tag ID, the user ID, the order data, and the like with the order data set. As a result, the seating position of the customer and the order contents of the customer are associated with each other.

(iii) Accounting processing When the store terminal 3 notifies that the serving of food and drink ordered by the customer is completed, the control unit 51 performs accounting processing on the customer's order data. For example, the control unit 51 updates the settlement database by creating a new record corresponding to the customer's user ID in the settlement database (see FIG. 6). The updated contents of the settlement database are provided to, for example, a payment system (not shown). For example, information such as a credit card registered in advance in a settlement database or the like is also provided to the payment system, and payment is completed without cash.

(1-3) Operation of the store management system of the present embodiment Next, the operation of the store management system 1 of the present embodiment will be described with reference to FIGS. 7 and 8.
FIG. 7 is a sequence chart showing the operation of the store management system 1 of the present embodiment. FIG. 8 is a diagram showing an example of an image displayed on the store terminal 3.

The sequence chart of FIG. 7 is described in association with an event from the customer's visit to the completion of accounting.
First, when a customer visits a store, the customer's user terminal 4 receives a packet including a tag ID, sensor data, and the like from each chair tag T1 in the store (step S2). Each time the user terminal 4 receives a packet from the chair tag T1, the user terminal 4 transmits the user ID, the tag ID included in the received packet, the sensor data, and the like to the application server 5 (step S3).
Each time the application server 5 receives the user ID, the tag ID, the sensor data, and the like, the application server 5 determines (detects) whether or not the customer is seated based on the sensor data and the like. If the customer has not yet been seated after coming to the store, the application server 5 does not detect that the customer has been seated based on the sensor data or the like acquired from the user terminal 4 of the customer, so that the user ID, tag ID, and sensor Discard data etc.

When the customer is seated in a certain chair, the application server 5 detects that the customer is seated based on sensor data or the like (step S10). The application server 5 updates the order data set based on the tag ID corresponding to the sensor data determined to be seating detection and the user ID transmitted together with the tag ID (step S12). That is, the application server 5 adds a new data line to the order data set, and writes the tag ID and the user ID in association with each other in the added data line. As a result, the user ID and the position information of the chair are associated with each other.
Next, the application server 5 may send a seating notification to the store application of the store terminal 3 (step S14).
The seating notification includes, for example, information that identifies the position of the chair for which seating detection has been made. Upon receiving the seating notification, the store terminal 3 displays, for example, the position of the chair for which seating has been detected on the store map (step S16). As a result, the store employee can know the seating position of the new customer and can take a predetermined action such as carrying water.

Next, an event is assumed in which the customer sits in a chair and orders food and drink from the customer application of the user terminal 4. The application server 5 receives the user ID and the order data from the customer application of the customer user terminal 4 (step S18).
The application server 5 updates the order data set based on the received user ID and order data (step S20). Specifically, the order data received in step S18 is written in a new data line (data line corresponding to the user ID received in step S18) of the order data set added in step S12.
Next, the application server 5 transmits an order notification to the store application of the store terminal 3 in response to the new data line of the order data set added in step S12 (step S22). The order notification includes, for example, a username, order details, and chair position code. The user name can be specified by referring to the settlement database based on the user ID. The order content is associated with the order ID. The chair position code is specified by referring to the store layout database based on the tag ID. The store application of the store terminal 3 updates the display content based on the order notification (step S24).

In step S24, the store application of the store terminal 3 presents the user ID or user name of the user terminal 4 associated with the position information of the chair, and the order data (request data) indicating the order contents acquired from the user terminal 4. (One example) is acquired and displayed via the application server 5.
FIG. 8 illustrates a screen G1 displayed on the display panel of the store terminal 3 by the store application based on the order notification. The screen G1 includes a store map 101 and an undelivered list 102. The unserved list 102 is a list of orders in which the serving does not live (a list of unserved orders), and is created based on the order notification. In the undelivered list 102, all unserved orders can be confirmed by operating the scroll bar 103. When any of the undelivered orders 102a is selected from the undelivered list 102, the serving position 104 (that is, the seating position of the corresponding customer) corresponding to the selected undelivered order 102a is displayed on the store map 101. Is preferable. As a result, the store employee can serve the food and drink included in the order data to the customer.
In the unserved order of FIG. 8, an example in which the corresponding user name is displayed is shown, but this is not the case. One or both of the user ID and the user name may be displayed.

When the store employee is ready to serve the food and drink ordered by the customer, the customer confirms the seating position of the customer by referring to the undelivered list displayed on the store terminal 3, and serves the food and drink.
After associating the tag ID with the user ID in step S12, the application server 5 does not change the tag ID received from the user terminal 4 at predetermined timings (that is, associates with the user ID in step S12). You may check (whether the tag ID is changed). When there is a change in the tag ID received from the user terminal 4 for a predetermined time or more, the application server 5 determines that the customer corresponding to the user ID has moved the seat, and sets the user ID and the changed tag ID. It is advisable to update the order data set so as to associate with each other and notify the store terminal 3. As a result, store employees can recognize that the chair in which the customer at the serving destination is seated has changed.
After the serving is completed, the store application transmits a serving completion notification to the application server 5 based on a predetermined operation on the store terminal 3 (step S26). The serving completion notification is a notification indicating that the serving of the food and drink ordered by the customer has been completed, and includes the user ID and the order data for which the serving has been completed.
Upon receiving the serving completion notification, the application server 5 performs accounting processing based on the order data for the user terminal 4 of the user ID included in the serving completion notification (step S28). That is, the application server 5 requests the user terminal 4 to execute electronic payment based on the order data acquired from the user terminal 4 associated with the position information of the chair.

In the accounting process, the application server 5 updates the settlement database by creating a new record corresponding to the customer's user ID in the settlement database (see FIG. 6). The updated contents of the settlement database are provided to, for example, a payment system (not shown). For example, information such as a credit card registered in advance in a settlement database or the like is also provided to the payment system, and payment is completed without cash.
In step S28, the application server 5 may transmit the accounting processing contents to the user terminal 4 for confirmation of payment or request for approval. For example, the application server 5 calculates the total amount of food and drink ordered by the user based on the order data, displays the calculated amount on the user terminal 4, and makes an inquiry as to whether or not to make a credit payment for the user. (That is, the user terminal 4 is requested to execute the electronic payment). When the application server 5 receives an instruction to make a credit card payment from the user terminal 4, the application server 5 cooperates with the payment system to execute the corresponding amount settlement process. As a result, the cashless payment is completed by the accounting process of the application server 5.
After the accounting process, the application server 5 updates the order data set (step S30). This order dataset update removes the data row corresponding to the served order data from the order dataset.

As described above, according to the store management system 1 of the present embodiment, since the seating position of the customer can be grasped in the store, it is not necessary for the employee of the store to come to the place where the customer is and take an order. Further, the customer's order is received by the application server 5, and the accounting process is performed without cash. As a result, it is possible to solve the labor shortage when operating the store.

(2) Second Embodiment Next, the store management system 1A according to the second embodiment will be described. In the description of the present embodiment, the same reference numerals will be given to the parts common to the store management system 1 of the first embodiment, and duplicate description will be omitted.

The store management system 1A of the present embodiment can further improve the detection accuracy of the seating position of the customer obtained by the store management system 1 of the first embodiment.
In the store management system 1 of the first embodiment, the customer user terminal 4 receives the packet from the chair tag, and the application server 5 detects whether or not the customer is seated based on the sensor data included in the packet. However, the customer's user terminal 4 may also receive packets from a plurality of surrounding chair tags, and the reception level of the packet from the chair tag of the chair in which the customer is seated is such that the radio wave is the customer. It may decrease when it is absorbed into the body of the chair.
Therefore, in the store management system 1A of the present embodiment, the store management system 1 of the first embodiment is further combined with a position identification system using a locator to further improve the detection accuracy of the customer's seating position. ..

(2-1) System Configuration of Store Management System of the Second Embodiment First, the system configuration of the store management system 1A of the present embodiment will be described with reference to FIG. FIG. 9 is a diagram schematically showing a system configuration of the store management system 1A of the present embodiment.
The store management system 1A of the present embodiment includes a receiver 6 (locator) and a position specifying device 7 with respect to the store management system 1 of the first embodiment. The store management system 1A of the present embodiment may have a gateway device 2 in the store.

The gateway device 2 is an optional element of the store management system 1A of the present embodiment. The gateway device 2 can receive the packet of the chair tag T1 in the store and transfer the received packet to the application server 5 via the network NW.
As described above, the chair tag T1 generates energy based on the radio waves of the surrounding environment, but when the radio waves of the surrounding environment are low, normal operations such as packet generation and wireless signal transmission are not performed. (For example, when the power mode is the first mode). Therefore, when the state in which communication with the chair tag T1 cannot be performed (for example, the state in which the advertising packet cannot be received) continues for a predetermined time or longer, the gateway device 2 starts wireless transmission or increases the transmission power. It is preferable to control. As a result, electric power can be stored because the radio waves in the surrounding environment of the chair tag T1 increase, and wireless communication with the gateway device 2 can be started or restarted.
As described in the first embodiment, when the user terminal 4 receives the packet of the chair tag T1 and transmits the user ID, the tag ID, and the sensor data to the application server 5, the gateway device 2 Does not have to be provided.
When the application server 5 receives the packet of the chair tag T1 via the gateway device 2, the application server 5 extracts the tag ID, sensor data, and the like from the received packet.

The receiver 6 and the position identification device 7 are communicably connected to each other, and constitute a position identification system for specifying the position of the user terminal 4 in the store. The receiver 6 is installed on the ceiling of the store, for example, receives a radio wave (beacon signal) radiated by a user terminal 4 of a visitor moving in the store, and measures the incident angle of the radio wave. The position specifying device 7 positions the user terminal 4 by an AOA (Angle of Arrival) method that specifies the position (position on a plane) of the user terminal 4 in the store based on the incident angle measured by the receiver 6.

The position of the user terminal 4 can be estimated by one receiver 6, but it depends on the magnitude of the received signal strength (RSSI) of the beacon signal transmitted from the user terminal 4, the store area, and the radio wave environment of the store. It is preferable to provide many receivers 6. The positioning method of the user terminal 4 is not limited to the AOA method, and other methods such as the TOA (Time of Arrival) method may be used.

(2-2) Configuration of Each Device of the Store Management System of the Present Embodiment Next, the configuration of each device of the store management system 1A of the present embodiment will be described with reference to FIG. FIG. 10 is a block diagram showing an internal configuration of each device of the store management system 1A of the present embodiment.

As shown in FIG. 10, the receiver 6 includes a radio wave receiving unit 61, an incident angle measuring unit 36, and a communication unit 63.
The radio wave receiving unit 61 includes an antenna that receives a beacon signal (radio wave) transmitted from the user terminal 4.
The incident angle measuring unit 62 measures the incident angle of the radio wave from the user terminal 4 received by the radio wave receiving unit 61.
The communication unit 63 is an interface for communicating with the user terminal 4 and the position specifying device 7. For example, the communication unit 63 demodulates the received signal from the user terminal 4. Further, the communication unit 63 functions as a communication interface between the receiver 6 and the position identification device 7, and the position identification device 7 associates the incident angle information measured by the incident angle measurement unit 62 with the terminal ID. Send to. The communication between the receiver 6 and the position specifying device 7 may be wired or wireless.

As shown in FIG. 10, the position specifying device 7 includes a control unit 71 and a communication unit 72.
The control unit 71 is mainly composed of a microprocessor and controls the entire position specifying device 7. For example, the microprocessor of the control unit 71 executes the position identification module (software) and identifies the position of the user terminal 4 based on the beacon signal transmitted from the user terminal 4 and including the terminal ID of the user terminal 4. .. The control unit 71 identifies the position of the user terminal 4 based on the information on the incident angle of the beacon signal received from the user terminal 4 by the receiver 6. More specifically, when using the AOA method, as described above, the known position of the receiver 6 in the store (the position of the three-dimensional coordinates based on the predetermined position of the store) and the receiver 6 Based on the information on the incident angle (arrival direction of radio waves) of the user terminal 4 sequentially acquired from, the position in the store area of the user terminal 4 (the position of the XY coordinates of the store floor) according to the passage of time is specified. (Positioning).
The control unit 71 sequentially transmits the identified position information (position information) of the user terminal 4 to the application server 5 via the communication unit 72 in association with the terminal ID of the user terminal 4.
The positioning interval of the user terminal 4 may be set arbitrarily, but it is set to a time (for example, several hundred ms or less) necessary for accurately grasping the position of the user terminal 4.

The communication unit 72 is a communication interface for communicating with the receiver 6 and communicating with the application server 5 via the network NW.
In the following description, the receiver 6 and the position specifying device 7 may be collectively referred to as a "position specifying system" as appropriate.

The control unit 51 of the application server 5 of the present embodiment has the position information of the user terminal 4 specified by the position identification device 7 and the position information of the chair corresponding to the tag ID of the chair tag having a predetermined change in the sensor data or the like. And, based on, the user ID received from the user terminal 4 and the tag ID of the chair tag are associated with each other. Since the tag ID of the chair tag and the position information of the chair are associated with each other in the store layout database, the user ID and the position information of the chair are associated with each other.
For example, when the position of the user terminal 4 specified by the position specifying device 7 and the position of the chair corresponding to the tag ID of the chair tag having a predetermined change in the sensor data or the like are equal to or less than a predetermined distance, the user It is determined that the user of the terminal 4 is seated in the chair, and the user ID of the user terminal 4 and the position information of the chair corresponding to the tag ID of the chair tag are associated with each other. The predetermined changes in the sensor data and the like are as described in the first embodiment.
That is, the approximate range in which the user terminal 4 is located is specified by the position specifying device 7, and the chair corresponding to the chair tag in which the sensor data has a predetermined change in the range is the seating position of the user of the user terminal 4. It can be judged that there is.
When the gateway device 2 receives the tag ID, the control unit 51 of the application server 5 sets the position information of the user terminal 4 specified by the position specifying device 7 and the position of the user terminal 4 within a predetermined range. Among the tag IDs received from the provided gateway device 2, the user ID of the user terminal and the position information of the chair are associated with each other based on the position information of the chair corresponding to the tag ID having a predetermined change in the sensor data or the like. You may.

(2-3) Operation of the store management system of the present embodiment Next, the operation of the store management system 1 of the present embodiment will be described with reference to FIG.
FIG. 11 is a sequence chart showing the operation of the store management system 1A of the present embodiment. Since the sequence chart of FIG. 11 differs from the sequence chart of FIG. 7 only in the processing from the customer's store visit event to the seating event, the description will be focused on the period from the store visit event to the seating event.

Each chair tag T1 in the store transmits a packet including the tag ID and sensor data to the application server 5 via the gateway device 2 (GW) or the user terminal 4 of the customer in the store (step S2). When a new customer visits the store, each chair tag T1 may be transmitted to the application server 5 via the customer's user terminal 4.
After the customer visits the store, the user terminal 4 of the customer transmits a beacon signal (step S4), and the beacon signal is received by the position identification system. The beacon signal includes the terminal ID of the user terminal 4. The position identification system performs position identification processing based on the received beacon signal and identifies the position of the user terminal 4 (step S6). The position identification system transmits the position data to the application server 5 in association with the terminal ID (step S8). Since the user ID and the terminal ID are associated with each other (see FIG. 6), the application server 5 can know the approximate position of the user corresponding to the user ID.
The processes of steps S4 to S8 are repeated at least until the user is seated.

Each time the application server 5 receives the tag ID and the sensor data from each chair tag T1, it determines (detects) whether or not the customer is seated based on the sensor data. If the customer has not yet been seated after coming to the store, the application server 5 does not detect that the customer has been seated based on the sensor data acquired from the user terminal 4 of the customer, and therefore discards the tag ID and the sensor data.

When the customer is seated in a certain chair, the application server 5 detects that the customer is seated based on sensor data or the like. Further, at the timing when the seating is detected, the application server 5 acquires the approximate position of the user corresponding to the user ID specified by the position specifying system. When the position of the chair specified based on the sensor data or the like at the timing when the customer's seating is detected and the approximate position of the user corresponding to the user ID are within a predetermined distance, the application server 5 is said to be the user. It is determined that the user is seated in the chair (step S10).
In FIG. 11, the processing after step S12 is the same as in FIG. 7.

As described above, according to the store management system 1A of the present embodiment, the accuracy of identifying the seating position of the customer can be improved by using the position identification system and the sensor data of the chair tag together.

(2-4) Modification Example Next, a modification of the store management system 1A of the present embodiment will be described. Any modification can be applied to the store management system 1 of the first embodiment.

(2-4-1) Modification 1
Modification 1 will be described with reference to FIG. FIG. 12 is a diagram showing an example of an image displayed on the store terminal 3.
In the above-described embodiment, the store terminal 3 has shown an example of displaying information viewed by store employees, such as an undelivered list, but the present invention is not limited to this. The store terminal 3 may be arranged at the entrance of the store or the like so that visitors can view information about vacant seats in the store.
FIG. 12 shows a screen G2 including vacant seat guidance information displayed by the store terminal 3. On the screen G2, in the store map 101, the vacant chair is displayed in a display mode different from that of the occupied chair. On the contrary, in the store map 101, the occupied chair may be displayed in a display mode different from that of the vacant chair.
In this modification, the application server 5 sequentially determines whether the corresponding chair is seated based on the sensor data or the like acquired from each chair tag in the store, and transmits the determination result to the store terminal 3. As a result of the determination, the store terminal 3 has the position information of the chair (that is, the occupied chair) associated with the user ID of the user terminal 4 in the store, or the chair that is not associated (that is, vacant). The position information of the chair) is acquired and displayed via the application server 5. In addition, the application server 5 has a chair to which a tag ID that cannot be associated with the above-mentioned user ID and cannot detect seating is attached for a predetermined period, or a tag ID that cannot detect seating because there is no change in sensor data, for example. It may be determined that the attached chair is empty.
The store terminal 3 displays vacant seat guidance information based on the determination result of the application server 5. By displaying the vacant seat information, store visitors can quickly select a seat after entering the store.

(2-4-2) Modification 2
Modification 2 will be described with reference to FIG. FIG. 13 is a diagram illustrating a positioning method of the user terminal 4.
The second modification is an example in which the chair tag is used to further improve the detection accuracy of the position of the user terminal 4. In this modification, the application server 5 associates the user ID of the user terminal 4 with the position information of the chair corresponding to the tag ID of the chair tag based on the RSSI value obtained from the chair tag acquired from the user terminal 4. For example, it is determined that the customer is seated in the chair corresponding to the chair tag indicating the largest RSSI value among the RSSI values obtained from the plurality of chair tags, and the user ID and the position information of the chair corresponding to the chair tag are used. May be associated with.
Further, the application server 5 may acquire the RSSI value of at least three or more chair tags in the user terminal 4 in the store area from the user terminal 4, and specify the position of the user terminal 4 based on the RSSI value. In this modification, the application server 5 is an example of the position specifying device.

FIG. 13 schematically shows a plan view of a six-seat chair and two tables in the store. Customers U1 to U3 are seated. Here, for example, in order to specify the position of the user terminal 4 of the customer U1, the chair tags T1-1, T1-2, and T1-3 of other chairs other than the seating position of the customer U1 can be used. Specifically, the distance between each chair tag and the user terminal 4 is estimated based on the RSSI values of the signals received from the plurality of chair tags on the user terminal 4 by using the radio wave attenuation characteristic according to the distance. The user terminal 4 is positioned by the triangulation method.

In the example shown in FIG. 13, the RSSI values of the received signals (packets) received by the user terminal 4 from the chair tags T1-1, T1-2, and T1-3 are S _R1 , S _R2 , and S _{R 3} , respectively. _{After the application server 5 acquires the RSSI value (SR1} , S _R2 , S _R3 ) of the received signal from each chair tag from the user terminal 4, the RSSI value and the known position of the chair corresponding to each chair tag are obtained. Based on the information (see FIG. 4), the user terminal 4 can be positioned by the triangulation method.

Since the radio wave propagation environment in the store is generally not an ideal free space, the positioning accuracy of the user terminal 4 can be further improved by using an arbitrary number of four or more chair tags for the positioning of the user terminal 4. It can also be increased. For example, when the user terminal 4 receives a packet from a plurality of chair tags of four or more, the user terminal 4 uses three chair tags from among the plurality of chair tags in descending order of RSSI value for positioning of the user terminal 4. Can be done.
Further, like the chair in which the customers U1 to U3 are seated in FIG. 13, the radio wave from the chair tag of the chair in which the customer is seated is absorbed in the customer's body, and the reception signal on the user terminal 4 is received. Since the level is lowered, the RSSI value corresponding to the distance from the user terminal 4 may not be observed in the user terminal 4. Therefore, when using the chair tag for positioning of the user terminal 4, it is preferable to use the chair tag that is not seated.

(2-4-3) Modification 3
Modification 3 will be described with reference to FIG. FIG. 14 is a diagram illustrating a positioning method of the user terminal 4.
Modification 3 is an example in which a plurality of gateway devices 2 are used to improve the accuracy of specifying the position of the user terminal 4. The user terminal 4 is positioned by using the RSSI value when a plurality of gateway devices 2 whose positions are known in the store receive the beacon signal from the user terminal 4.
The position where the gateway devices 2 are arranged is not limited, but in the example shown in FIG. 14, an example in which the gateway devices 2 are arranged at equal intervals in a matrix on the ceiling of the store is shown.

In this method, when each gateway device 2 receives a packet from the user terminal 4, the device ID for identifying its own device and the RSSI value when the beacon signal is received from the user terminal 4 are transmitted to the application server 5. Send. For example, in FIG. 14, the RSSI values when the beacon signal is received from the user terminal 4 are SR1, SR2, SR4, SR5 in the gateway devices 2-1, 2-2, 2-4, 2-5, respectively. .. In this example, the RSSI value in the gateway devices 2-3 and 2-6 is assumed to be very small and ignored.

Here, as in the modified example 2, the distance between the user terminal 4 and each gateway device is estimated based on the RSSI value of each gateway device by using the radio wave attenuation characteristic according to the distance, and the user is subjected to the triangulation method. Position the terminal 4.
For example, in FIG. 14, after acquiring the RSSI values of each gateway device, the application server 5 has three RSSI values (for example, SR1, SR2, SR5) in descending order and known positions of the gateway devices corresponding to each RSSI value. Based on the information, the user terminal 4 can be positioned by the triangulation method. Further, since the radio wave propagation environment in the store is generally not an ideal free space, the positioning accuracy of the user terminal 4 can be further improved by using an arbitrary number of four or more gateway devices for the positioning of the user terminal 4. It can also be increased.

(3) Third Embodiment Next, the store management system 1B according to the third embodiment will be described. In the description of the present embodiment, the same reference numerals will be given to the parts common to the store management systems of the first and second embodiments, and duplicate description will be omitted.

(3-1) System Configuration of Store Management System of Third Embodiment First, the system configuration of the store management system 1B of this embodiment will be described with reference to FIG. FIG. 15 is a diagram schematically showing a system configuration of the store management system 1B of the present embodiment.

It is a point. The tableware tag T2 is attached to, for example, the bottom of the tableware TW1.

In the store management system 1B of the present embodiment, the tableware tag T2 is used to confirm whether or not all the foods and drinks to be served to the customer have been served. Before serving the tableware TW1 to the customer, the store performs a process of associating the customer's user ID or order data with the tag ID of the tableware tag T2 in the store application of the store terminal 3.
The application server 5 determines whether or not the order corresponding to the order data (an example of the request data) has been executed based on the position information of the user terminal 4 and the position information of the tableware tag T2 specified by the position specifying device 7. More specifically, after the food and drink are served to the customer, the application server 5 determines whether the position of the chair detected when the customer is seated and the position of the tableware tag T2 are equal to or less than a predetermined distance. By doing so, it is confirmed whether or not the food and drink as ordered is served to the customer.

The configuration of the tableware tag T2 is the same as the configuration of the chair tag T1 shown in FIG. The tableware tag T2 includes, for example, data (sensor data) of at least one of the weight (load) applied to the tableware tag T2, the movement of the tableware tag T2, the ambient temperature of the tableware tag T2, and the tag ID.

(3-2) Operation of the store management system of the present embodiment Next, the operation of the store management system 1B of the present embodiment will be described with reference to FIG.
FIG. 16 is a sequence chart showing the operation of the store management system 1B of the present embodiment. The sequence chart of FIG. 16 shows only the parts before and after the serving event, and the processing of the sequence charts of FIGS. 7 and 11 can be applied to the other parts.

In FIG. 16, before serving food and drink to the customer, the store application of the store terminal 3 receives a packet including the tag ID of the tableware tag T2 to be served, and the tag ID and the customer's user ID and / or The order data is associated with the order data (step S38). The customer's user ID and order data are included in the undelivered list (see FIG. 8), and these data are associated with the tag ID of the tableware tag T2. Information in which the tag ID of the tableware tag T2 is associated with the customer's user ID and / or order data is transmitted from the store terminal 3 to the application server 5 in order to perform the confirmation process in step S46, which will be described later. It may be held in the application server 5.

The dishes are ready to be served, and at the serving event, the dishes are served at the customer's seating position. At this point, the seating position of the customer has already been specified.
The position identification system receives a packet from the tableware tag T2 attached to the served tableware (step S40), performs a process of identifying the position of the tableware based on this received signal (step S42), and uses the tableware tag T2. The tag ID and the position data are transmitted to the application server 5 (step S44).
The application server 5 confirms whether the position of the tableware acquired in step S44 and the seating position (user position) of the customer are equal to or less than a predetermined distance (step S46). If the distance is less than or equal to the predetermined distance, the application server 5 determines that the food is served correctly. If it exceeds a predetermined distance, it can be determined that the food is not served correctly and the store terminal 3 can be notified. Further, the application server 5 refers to the customer's order data after a lapse of a predetermined time from the start of serving, and determines whether or not the serving is completed as ordered. The application server 5 transmits a confirmation result notification including the confirmation result of step S46 to the store application of the store terminal 3 (step S48). The store terminal 3 displays an image showing whether or not the tableware is properly served to the customer based on the received confirmation result notification (step S50).

As described above, according to the store management system 1B of the present embodiment, by using the tableware tag T2, the store employee confirms whether or not the food and drink as ordered is served to the customer. Can be done.

(4) Fourth Embodiment Next, the store management system 1B according to the fourth embodiment will be described. The configuration of the store management system 1B of the present embodiment may be the same as that of the third embodiment. In the description of the present embodiment, the same reference numerals are given to the parts common to the store management system of the first and second embodiments, and duplicate description is omitted.

In the store management system 1B of the present embodiment, the tableware tag T2 (an example of the third wireless tag) is used so that the store employee can appropriately determine the timing of replacing the food and drink served to the customer or the replacement. Is attached to a container containing food and drink corresponding to the order data acquired from the user terminal 4 associated with the position information of the chair in the store. The application server 5 detects at least one of the load (or weight) on the tableware, the movement of the tableware, the ambient temperature of the tableware, the remaining amount in the tableware, etc. from the tableware tag T2 attached to the tableware. Acquire some sensor data.
When there is a predetermined change in the sensor data of the tableware tag T2, the application server 5 determines that the food and drink replacement condition or the food and drink replacement condition is satisfied, and notifies the store terminal 3. Based on the notification, the store employee provides the customer with a food and drink replacement service or a food and drink replacement service. The notification transmitted from the application server 5 to the store terminal 3 is an example of a request for executing an order corresponding to the order data acquired from the user terminal 4.

The conditions for replacing food and drink are not limited, but for example, when the sensor data of the tableware tag T2 includes data related to temperature, weight, etc., for example, the temperature may be lower than the predetermined temperature and the weight may be equal to or higher than the predetermined temperature. .. For example, when the food or drink is coffee, the store terminal 3 is notified to prompt the replacement of coffee when the coffee has cooled down even though it is sufficiently left in the tableware.

The conditions for substituting food and drink are not limited, but for example, when the sensor data of the tableware tag T2 or the like includes data related to the weight or the like, the weight may be less than a predetermined value, for example. For example, when the food and drink is coffee and the tableware is empty, the store terminal 3 is notified to prompt the replacement of coffee. The food and drink replacement condition may be a condition that, for example, when the sensor data of the tableware tag T2 includes the movement data of the tableware tag T2, the predetermined movement with respect to the tableware tag T2 exceeds a predetermined number of times. This is because if the customer moves the tableware frequently, the contents in the tableware are considered to be sufficiently low.

Next, the operation of the store management system 1B of the present embodiment will be described with reference to FIG.
FIG. 17 is a sequence chart showing the operation of the store management system 1B of the present embodiment. The sequence chart of FIG. 17 shows only the parts before and after the serving event, and the processing of the sequence charts of FIGS. 7 and 11 can be applied to the other parts.

In FIG. 17, before serving food and drink to the customer, the store application of the store terminal 3 receives a packet including the tag ID of the tableware tag T2 to be served, and the tag ID and the customer's user ID and / or The order data is associated with the order data (step S38). The customer's user ID and order data are included in the undelivered list (see FIG. 8), and these data are associated with the tag ID of the tableware tag T2. Information in which the tag ID of the tableware tag T2 is associated with the user ID and / or order data of the customer is transmitted from the store terminal 3 to the application server 5 in order to make the determination in step S62, which will be described later, and the application. It may be held in the server 5.

The dishes are ready to be served, and at the serving event, the dishes are served at the customer's seating position. At this point, the seating position of the customer has already been specified.
The application server 5 sequentially receives packets including the tag ID and sensor data from the tableware tag T2 of the tableware served to the customer via the user terminal 4 or the gateway device 2 (GW) (step S60). Then, each time the application server 5 receives the packet, it determines whether or not the replacement condition or the replacement condition is satisfied based on the sensor data or the like included in the packet, the customer's user ID, the customer's order data, or the like ( Step S62). When the replacement condition or the replacement condition is satisfied (step S62: YES), the application server 5 transmits a notification for prompting the food and drink replacement service or the food and drink replacement service to the store terminal 3 (step S64). ).

According to the store management system 1B of the present embodiment, by using the tableware tag T2, an employee can come to the customer's seating position and replace the food and drink provided to the customer without checking the customer's tableware. The replacement service can be provided at the right time.

The store management system 1B of the present embodiment can also be applied when providing a course meal. For example, in a course meal, when products A, B, and C are provided to customers in order, products A, B, and C are arranged on tableware with different tableware tags, and each tableware tag is served. The tag ID and the order ID corresponding to each of the A product, the B product, and the C product are associated in advance. Then, when the application server 5 determines that the contents of the product A are empty or small based on the sensor data of the tableware tag, the application server 5 transmits a notification instructing the store terminal 3 to serve the product B. Similarly, when the application server 5 determines that the contents of the product B are empty or small, the application server 5 transmits a notification instructing the store terminal 3 to serve the product C.

(5) Fifth Embodiment Next, the store management system 1C according to the third embodiment will be described with reference to FIGS. 18 to 20. In the description of the present embodiment, the same reference numerals will be given to the parts common to the store management system of the first to fourth embodiments, and duplicate description will be omitted.
FIG. 18 is a diagram schematically showing a system configuration of the store management system 1C of the present embodiment. FIG. 19 is a diagram showing a data configuration example of the store layout database of the present embodiment. FIG. 20 is a sequence chart showing the operation of the store management system 1C of the present embodiment.

In the store management system 1C of the present embodiment, a table tag T3 is attached as an IoT tag to each table TB in the store in order to prevent a mistake in serving food and drink ordered by the customer. The table tag T3 is arranged, for example, on the surface on which the tableware is served. The table tags T3 may be arranged at predetermined intervals on the serving surface of the table.
The configuration of the table tag T3 is the same as the configuration of the chair tag T1 shown in FIG. 2, for example, sensor data of at least one of weight (load on the table), movement of the table, ambient temperature of the table, and the like. Is detected. When tableware is served on the table, the temperature and weight indicated by the sensor data of the table tag T3 rise due to the increase in the weight added to the table TB by the tableware and the radiant heat due to the heat conduction of the contents in the tableware. Is shown. Therefore, based on the sensor data of the table tag T3 and the like, it is possible to determine whether or not the table TB has been served.

As shown in FIG. 19, in the store layout database of the present embodiment, the tag ID of the table tag is associated with the tag ID of the chair tag. The table tag and chair tag to which the tag ID is associated means that the corresponding tables and chairs are laid out in combination in the store.

Next, the operation of the store management system 1C of the present embodiment will be described with reference to FIG. The sequence chart of FIG. 20 shows only the parts before and after the serving event, and the processing of the sequence charts of FIGS. 7 and 11 can be applied to the other parts.
Each table tag T3 in the store sequentially transmits packets including the tag ID and sensor data to the application server 5 via the user terminal 4 or the gateway device 2 (GW) (step S70). Each time the application server 5 receives a packet, it determines whether or not it has been served in the corresponding table based on the sensor data or the like included in the packet, the customer's user ID, the customer's order data, or the like (step S72). If not served, the application server 5 discards the corresponding packet.

When the tableware is served at the customer's table after the serving event, the application server 5 determines that the tableware has been served based on the change in the sensor data or the like acquired from the table tag T3 (step S72: YES). Next, does the application server 5 associate the tag ID of the table tag of the table determined to be served with the tag ID of the chair tag of the chair whose seating has been detected in the store layout database (see FIG. 19)? Check whether or not (step S74). A confirmation result notification including the confirmation result of step S74 of the application server 5 is transmitted to the store terminal 3 (step S76). Upon receiving the confirmation result notification, the store terminal 3 updates the display content (step S78).

According to the store management system 1C of the present embodiment, it is possible to verify whether or not the food and drink ordered by the customer is served at the corresponding table by using the sensor data of the table tag T3 and the like.

Although the information processing apparatus, the information processing system, and the embodiment of the program of the present invention have been described above, the present invention is not limited to the above-described embodiment. Further, the above-described embodiment can be improved or modified in various ways and a combination of the above-described embodiments can be combined without departing from the gist of the present invention.

In the above-described embodiment, the case where the IoT tag (chair tag T1, tableware tag T2, table tag T3) has a built-in sensor and transmits a packet including the sensor data has been illustrated, but the present invention is not limited to this. The IoT tag attached to the chair, tableware, table, etc. described above has a waveform that changes according to, for example, the load (or weight) on the object to be attached, the movement of the object to be attached, the ambient temperature of the object to be attached, and the like. A wireless signal is transmitted, and for example, a tag management server or a terminal device connected to a network analyzes the waveform of the wireless signal transmitted from the IoT tag, and detects the result of the analysis, weight, movement, ambient temperature, etc. For example, it may be provided to the application server 5 or the like.
Further, the tag management server may authenticate the tag ID included in the packet transmitted from each tag. Further, in the above-described embodiment, the position identification system identifies the position of the tableware tag T2 by receiving the packet of the tableware tag T2, but the sensor data of the chair tag T1, the tableware tag T2, and the table tag T3. Etc. may be received and the application server 5 may detect a predetermined change in each tag.

In the above-described embodiment, for example, an example in which the position of the chair is fixed has been described, but the present invention is not limited to this, and the case where the position of the chair is not fixed is also applicable. Even when the position of the chair is not fixed, the user ID and the position information of the chair can be associated with each other by the following method, for example. In either method, the position information of the chair is specified by the position specifying device 7 or the like based on the received signal of the packet including the corresponding tag ID.
(i) The position identification device 7 or the like specifies the position information of the user terminal 4 and the position information of the chair corresponding to the tag ID of the chair tag having a predetermined change in the sensor data or the like, and the position information of the user terminal 4 and the like. Based on the position information of the chair, the user ID corresponding to the user terminal 4 and the position information of the chair are associated with each other. For example, when the position indicated by the position information of the user terminal 4 and the position indicated by the position information of the chair are within a predetermined distance, the user ID of the user terminal 4 and the position information of the chair are associated with each other.
(ii) A chair corresponding to the position information of the user terminal 4 and the tag ID having a predetermined change in sensor data or the like among the tag IDs received from the gateway device 2 provided within a predetermined range from the position of the user terminal 4. The position information of the user terminal may be specified by the position specifying device 7 or the like, and the user ID of the user terminal and the position information of the chair may be associated with each other based on the specified position information.
(iii) As shown in FIG. 13, the position of the chair in which the user of the user terminal 4 is seated based on the RSSI value of the received signal in the user terminal 4 of the packet transmitted from the plurality of chair tags whose positions have been specified. Information may be specified. As a result, the user ID corresponding to the user terminal 4 and the position information of the chair are associated with each other.
