For example, as shown in FIG. 4, a general BLE advertising packet is periodically (for example, at intervals of 20 ms) in three channels of 37 channels (32a), 38 channels (32b), and 39 channels (32c). Sent by the base station. The mobile station scans the advertising packet while sequentially switching the three channels at

predetermined periods

30a, 30b, and 30c (for example, at intervals of 25 ms).

However, when using a plurality of channels, the received radio wave intensity measured based on the advertising packet received by the mobile station is not stable. Therefore, in the present embodiment, as shown in FIG. 5, the base station 10 fixes the channel used for transmitting the advertising packet to one channel (for example, 37 channels (30a)).

Here, in order for the mobile station 20 to reliably receive the advertising packet transmitted by the base station 10, the advertising packet may be constantly scanned. However, when the mobile station 20 constantly scans, power consumption increases. In this case, low power consumption which is an advantage of BLE cannot be realized. Therefore, the base station 10 transmits an advertising packet at a predetermined period (for example, at an interval of 100 ms) in one channel. The mobile station 20 scans the advertising packet at a predetermined cycle (for example, at an interval of 500 ms) using only one channel. Further, the mobile station 20 transmits the intensity information to the employee management apparatus 100 in the scan stop period 34 after the scan execution period 30a. The mobile station 20 transmits intensity information to the employee management apparatus 100 using a UDP packet during a scan stop period 34 between the current scan execution period 30a and the next scan execution period 30a.

The BLE module 22 derives the received radio wave intensity of each mobile station 20 of the plurality of base stations 10 based on the advertising packet received from each of the plurality of base stations 10. The BLE module 22 determines the top six base stations of received radio wave intensity (RSSI) from the scanned advertising packet (S104). The WiFi module 24 transmits, to the employee management apparatus 100, the base station IDs of the upper six RSSI stations and the strength information indicating the respective RSSIs in the second period after the first period has elapsed (S108). When the second period elapses, the BLE module 22 restarts the advertising packet scan.

Based on the distance to the mobile station 20 for each base station 10 derived by the deriving unit 112 based on the strength information, the identifying unit 114 determines that the distance from the plurality of base stations 10 to the mobile station 20 is the third. A short third base station may be identified. The specifying unit 114 is an example of a first specifying unit, a second specifying unit, and a third specifying unit.

The position determination unit 116 includes a first position indicating the position of the first base station, a second position indicating the position of the second base station, and the first received radio wave intensity at the mobile station with respect to the first base station. The position of the mobile station 20 may be determined based on The position determination unit 116 may determine the position of the mobile station 20 based further on the third position indicating the position of the third base station.

The position determination unit 116 determines a second point on the circumference whose first center is the first position of the first base station and whose radius is the first distance indicating the distance from the first base station to the mobile station 20. The position of the mobile station 20 may be determined based on the second position of the base station. The position determination unit 116 determines a point on the circumference whose center is the first position of the first base station and whose radius is the first distance as the second position of the second base station and the third position of the third base station. The position of the mobile station 20 may be determined based on the three positions. The position determination unit 116 has a second point closest to the second position of the second base station on the circumference whose center is the first position of the first base station and whose radius is the first distance, The intermediate first point on the arc between the third point closest to the third position of the third base station may be determined as the position of the mobile station 20. The position determining unit 116 moves from the intermediate first point on the arc to the second point or the third point side based on the ratio of the received radio wave intensity of the second base station and the received radio wave intensity of the third base station. A point on the shifted arc may be determined as the position of the mobile station 20.

The position determination unit 116 associates in advance with a first base station (a base station 10 closest to the mobile station 20 or a base station 10 having the highest received radio wave intensity at the mobile station 20) among the plurality of base stations 10. The second base station may be identified from among the plurality of base stations that are provided. The shorter the distance from the source to the destination, the more likely there are fewer obstacles. Therefore, the shorter the distance from the transmission source to the reception destination, the smaller the variation in received radio wave intensity. Therefore, the shorter the distance from the transmission source to the reception destination, the smaller the variation in the distance derived from the received radio wave intensity. The mobile station 20 is most likely to be near the base station having the highest received radio wave intensity, that is, the closest distance. Therefore, the position determination unit 116 may determine the position of the base station with the highest received radio wave intensity as the position of the mobile station 20. However, there is a possibility that the position of the mobile station 20 cannot be accurately identified only from the position of one base station 10. Therefore, the position determination unit 116, among the other base stations 10 close to the first base station, receives the second base station having the next highest received radio wave intensity after the first base station, and further receives the next radio wave. A third base station with high strength is identified. Then, the position determination unit 116 includes the first position of the first base station, the first distance from the first base station to the mobile station 20, the second position of the second base station, and the third base station. The position of the mobile station 20 may be determined based on the third position.

The map information storage unit 130 stores map information of a space where a plurality of base stations 10 are arranged. The map information storage unit 130 may store a floor map of a store where a plurality of base stations 10 are arranged as map information. The base station information storage unit 132 stores the positions of the plurality of base stations 10 on the map and the base station IDs of the base stations 10 associated in advance for each base station ID of the base station 10. The base station 10 associated in advance is a base station 10 located in the vicinity of each base station 10. For example, the base station 10 associated in advance with the first base station is a base station existing within a circle with a predetermined radius centered on the position of the first base station with respect to the first base station. It's okay. The user refers to the floor map, designates another base station 10 associated with each base station 10, and the base station information storage unit 132 selects the pre-associated base station 10 designated by the user. A table shown for each base station 10 may be stored.

The position determination unit 116 refers to the map information and the base station information, the first position of the first base station, the first distance from the first base station to the mobile station 20, and the second base station information. The position of the mobile station 20 may be determined based on the second position and the third position of the third base station.

The strength information provided from the mobile station 20 to the employee management apparatus 100 shows only the received radio wave intensity for the top six stations of the received radio wave intensity among the plurality of base stations 10. Therefore, among the other five stations other than the first base station with the highest received radio wave intensity indicated in the strength information, the base station associated with the first base station, that is, the vicinity of the first base station in advance. The associated base station is not necessarily included.

Accordingly, the position determination unit 116 moves the first position of the first base station when none of the plurality of base stations 10 associated in advance exists among the plurality of base stations 10 indicated in the strength information. The position of the station 20 may be determined. When only one base station 10 associated in advance is included in the plurality of base stations 10 indicated in the strength information, the position determination unit 116 determines that the first base station The position of the mobile station 20 may be determined based on the first position, the first distance from the first base station to the mobile station 20, and the second position of the second base station.

The specifying unit 114 may specify a candidate base station of the first base station that is closest to the mobile station 20 from the plurality of base stations 10 based on the intensity information at the first time point. . Further, when the candidate base station satisfies the first condition in which the distance from the candidate base station to the mobile station 20 is equal to or less than a predetermined first threshold, the specifying unit 114 sets the candidate base station to the first base station You may identify as the 1st base station of a time.

Based on the latest strength information received from the mobile station 20 (current strength information), the specifying unit 114 selects the first base station whose distance from the plurality of base stations 10 to the mobile station 20 is the first closest. Candidate base stations may be identified. For example, when the candidate base station satisfies the first condition that the distance from the candidate base station to the mobile station 20 is 100 cm or less, the specifying unit 114 specifies the candidate base station as the current first base station. You can do it.

The specifying unit 114 determines whether the candidate base station specified based on the intensity information at the first time does not satisfy the first condition and the candidate base station specified based on the intensity information at the first time The distance from the candidate base station to the mobile station 20 is determined based on the intensity information at the second time point before the first time point when the distance to the mobile station 20 is equal to or less than a predetermined second threshold value. If the second condition that is less than or equal to the second threshold is satisfied, the candidate base station may be identified as the first base station at the first time point.

The identifying unit 114 determines that the candidate base station identified based on the latest strength information does not satisfy the first condition, and the distance from the candidate base station identified based on the latest strength information to the mobile station 20 is If the second condition is 200 cm or less and the distance from the candidate base station specified based on the previous strength information to the mobile station 20 is 200 cm or less, the candidate base station You may specify as a base station.

The specifying unit 114 is configured such that the candidate base station specified based on the strength information at the first time does not satisfy the first condition and the second condition, and the candidate base station has the first time point, the second time point, And the third time point before the second time point, when the third shortest distance among the plurality of base stations 10 to the mobile station 20 satisfies the third condition, the candidate base stations are You may identify as the 1st base station of 1 time.

The specifying unit 114 is configured such that the candidate base station specified based on the latest strength information does not satisfy the first condition and the second condition, and the candidate base station is the current time, the previous time, and the previous time, When the third condition where the distance to the mobile station 20 is consecutively shortest among the plurality of base stations 10 indicated by the strength information satisfies the third shortest condition, the candidate base station is identified as the current first base station. It's okay.

FIG. 8 is a flowchart showing an example of a processing procedure for determining the position of the mobile station 20 by the employee management apparatus 100. The employee management apparatus 100 may execute the process shown in FIG. 8 every time the strength information is received from the mobile station 20.

The strength information acquisition unit 102 acquires strength information from the mobile station 20 (S200). The deriving unit 112 derives the distances from the base stations of the top six RSSI stations indicated in the strength information to the mobile station 20 (S202). The specifying unit 114 specifies the base station 10 that is closest to the mobile stations 20 among the top six base stations (S204). First, the specifying unit 114 determines whether or not there is a base station that satisfies the first condition (for example, the distance to the mobile station 20 is 100 cm or less) among the top six base stations. For example, as illustrated in FIG. 9, the derivation unit 112 registers the distances of the top six base stations in a table in which the base station ID is associated with the current, previous, and previous distances. The identifying unit 114 refers to the table and identifies the base station ID: 19 as the first closest base station 10.

When there is no base station that satisfies the first condition among the top six base stations, the specifying unit 114 determines that the second condition (for example, the current and previous ones) is included in the top six base stations. It is determined whether or not there is a base station that satisfies a distance to the mobile station 20 of 200 cm or less continuously. For example, the specifying unit 114 refers to the table shown in FIG. 10 and specifies the base station ID: 19 as the first base station 10 that satisfies the second condition.

When there is no base station satisfying the first condition and the second condition among the base stations of the upper six stations, the specifying unit 114 sets the third condition (for example, This time, it is determined whether or not there is a base station that satisfies the distance from the previous mobile station 20 to the previous mobile station 20 that is the shortest among the top six stations. For example, the identifying unit 114 refers to the table illustrated in FIG. 11 and identifies the base station ID: 12 as the first closest base station 10 that satisfies the third condition.

On the other hand, when there is no base station that satisfies the first condition, the second condition, and the third condition among the top six base stations, the specifying unit 114 does not have the first closest base station. Judge. The specifying unit 114 refers to the table shown in FIG. 12 and determines that there is no first closest base station among the top six base stations.

If the identifying unit 114 can identify the first closest base station, the identifying unit 114 then identifies the second closest base station among the top six base stations with the distance to the mobile station 20 (S206). The identifying unit 114 determines whether or not there is a base station associated in advance with the first nearest base station among the top six base stations. The specifying unit 114 may determine whether or not there is a base station that is predetermined as a base station that is closest to the first base station among the top six base stations. If there are a plurality of such base stations, the identifying unit 114 identifies the base station with the shortest distance from the plurality of base stations as the second closest base station.

The specifying unit 114 may specify the base station associated with the first closest base station with reference to a table as illustrated in FIG. 13 in which nearby base stations are registered in association with each base station. For example, when the first closest base station is the base station ID: 02, the specifying unit 114 sets the

base station IDs

01, 03, 20, and 24 as the base stations associated with the first closest base station. Identify. Further, the specifying unit 114 refers to a table indicating the distance from the mobile station 20 to each of the upper six base stations as shown in FIG. 14, and the base station ID: 03 is the second closest base station. Is specified.

When the identifying unit 114 can identify the second closest base station, the identifying unit 114 subsequently identifies the third closest base station among the top six base stations with the distance to the mobile station 20 (S208). The identifying unit 114 refers to the table indicating the distance from the mobile station 20 to each of the upper six base stations as illustrated in FIG. 14 and identifies that the third nearest base station is the base station ID: 24. To do.

For example, the identifying unit 114 refers to a table indicating the distance from the mobile station 20 to each of the upper six base stations as shown in FIG. 15, and the base station ID: 01 is the base station closest to the first base station. Is identified. Furthermore, the specifying unit 114 specifies the base station IDs: 02, 20, 24, and 26 near the base station ID: 01 with reference to the table shown in FIG. The specifying unit 114 specifies that the second nearest base station is the base station ID: 24 with reference to the table shown in FIG. On the other hand, since the base station IDs other than the

base station IDs

01 and 24 are not registered as the nearby base station IDs in the table shown in FIG. 15, the specifying unit 114 does not have the third closest base station. Judge.

Next, when the identifying unit 114 can identify the first, second, and third closest base stations from among the top six base stations, the position determining unit 116 first, second, and third. Based on the position of the closest base station and the distance of the first closest base station, the position of the mobile station 20 is determined (S210). When the specifying unit 114 can specify only the first and second closest base stations among the top six base stations, the position determining unit 116 determines the positions of the first and second closest base stations, The position of the mobile station 20 is determined based on the distance of the base station closest to the th (S212). When the specifying unit 114 can specify only the first closest base station among the top six base stations, the position determining unit 116 determines the position of the current mobile station 20 based on the position of the first closest base station. Is determined (S214). The position determination unit 116 may determine the position of the base station that is closest to the current position of the mobile station 20.

The position determination unit 116 determines the current position of the mobile station 20 and then determines the current position of the mobile station 20 based on the last four positions of the mobile station 20 (S216). The position determination unit 116 may determine the current position of the mobile station 20 by deriving the average of the positions of the last four mobile stations 20. The position determination unit 116 may determine the current position of the mobile station 20 by deriving a moving average of the positions of the mobile stations 20 in the past four times.

As described above, considering that the higher the received radio wave intensity, the higher the accuracy of the received radio wave intensity, the higher the received radio wave intensity at the mobile station 20 for each base station 10, the higher the mobile station 20. The selection condition of the base station 10 near is switched. Thereby, it is possible to suppress variation in the selection accuracy of the base station 10 due to the high received radio wave intensity. Therefore, it is possible to prevent variation in the accuracy of the determined position of the mobile station 20 due to the high received radio wave intensity.

Incidentally, the received radio wave intensity varies depending on the presence or absence of obstacles around the mobile station 20. For example, when the base station 10 is installed on the table 80, the received radio wave intensity varies depending on the usage status of the table 80. The accuracy of determining the position of the mobile station 20 based on the received radio wave intensity also varies depending on the presence or absence of obstacles around the mobile station 20.

Here, the POS system 200 manages the usage status of the table 80 in the database 202. That is, if the table 80 is in use, there is a person around the table 80, which may affect radio waves transmitted from the base station 10 installed on the table 80. There is a possibility that the received radio wave intensity at the mobile station 20 may decrease. Here, the table 80 in use is a concept including the table 80 assigned to a customer regardless of whether or not the table 80 actually has a customer. The table 80 in use becomes the target table 80 when it is assigned to a customer and registered in the database 202. When the customer payment of the table 80 is completed or when the customer payment is completed and the cleaning of the table 80 is completed, the usage information of the table 80 managed in the database 202 is updated from being used to vacant. Is done.

Therefore, the determination unit 110 may determine the position of the mobile station 20 based on the usage information indicating the usage status of the area such as the table 80 in which the base station 10 is installed and the strength information. When the usage information indicates that the first area of the plurality of areas is used, the determination unit 110 receives the first base station installed in the vicinity of the first area indicated by the strength information. The radio wave intensity may be increased according to a predetermined increase condition, and the position of the mobile station 20 may be determined based on the increased received radio wave intensity.

When the usage information indicates that the first area is used, the derivation unit 112 indicates that the first area is used, rather than when the first area is not used. The strength information is such that the distance from the first base station to the mobile station 20 derived based on the received radio wave strength at the mobile station 20 with respect to the first base station installed in the vicinity of the first region is shorter. The distance from the first base station to the mobile station 20 that is derived based on the received radio wave intensity for the first base station shown in FIG.

The derivation unit 112 refers to the usage information and identifies the base station 10 installed in the table 80 registered as being used, among the top 6 base stations 10 indicated in the strength information. If the corresponding base station 10 exists, the deriving unit 112 may correct the received radio wave intensity by adding a predetermined increment to the received radio wave intensity for the base station 10.

FIG. 16 is a flowchart illustrating an example of a processing procedure for determining the position of the mobile station 20 using the usage information.

The strength information acquisition unit 102 acquires strength information from the mobile station 20 (S300). The usage information acquisition unit 104 acquires usage information indicating the usage status of each table 80 from the POS system 200 (S302). The deriving unit 112 corrects the intensity information based on the usage status (S304). When the base station 10 associated with the table 80 being used exists in the base station 10 indicated by the strength information, the deriving unit 112 determines the received radio wave strength of the base station 10 by a predetermined increment. increase. For example, the strength information acquisition unit 102 acquires strength information indicating the base station ID and RSSI of the top six stations with the received radio wave strength as shown in FIG. Also, the usage information acquisition unit 104 acquires usage information indicating the usage status of the table corresponding to the base station IDs of the top six stations as shown in FIG. The deriving unit 112 identifies the

base station IDs

19 and 27 of the base station 10 corresponding to the table 80 being used. As shown in FIG. 19, the deriving unit 112 corrects the received radio wave intensity corresponding to the table 80 in use by adding 10 to the RSSI of the corresponding base station ID.

Next, the deriving unit 112 derives the distance from each base station of the top six RSSI stations indicated in the corrected strength information to the mobile station 20 (S306). The specifying unit 114 specifies the base station 10 that is the closest to the top six base stations in the distance to the mobile station 20 (S308).

First, the specifying unit 114 determines whether there is a base station that satisfies the first condition (for example, the distance to the mobile station 20 is 100 cm or less) among the top six base stations. When there is no base station that satisfies the first condition among the top six base stations, the specifying unit 114 determines that the second condition (for example, the current and previous ones) is included in the top six base stations. It is determined whether or not there is a base station that satisfies a distance to the mobile station 20 of 200 cm or less continuously. When there is no base station satisfying the first condition and the second condition among the base stations of the upper six stations, the specifying unit 114 sets the third condition (for example, This time, it is determined whether or not there is a base station that satisfies the distance from the previous mobile station 20 to the previous mobile station 20 that is the shortest among the top six stations. When there is no base station that satisfies the first condition, the second condition, and the third condition among the top six base stations, the specifying unit 114 determines that there is no base station that is closest to the first condition. To do.

When the first closest base station can be specified, the specifying unit 114 then specifies the second closest base station among the top six base stations with the distance to the mobile station 20 (S310). The identifying unit 114 determines whether or not there is a base station associated in advance with the first nearest base station among the top six base stations. The specifying unit 114 may determine whether or not there is a base station that is predetermined as a base station that is closest to the first base station among the top six base stations. If there are a plurality of such base stations, the identifying unit 114 identifies the base station with the shortest distance from the plurality of base stations as the second closest base station. If the identifying unit 114 can identify the second closest base station, the identifying unit 114 subsequently identifies the third closest base station among the top six base stations with the distance to the mobile station 20 (S312).

When the identifying unit 114 can identify the first, second, and third closest base stations from among the top six base stations, the position determining unit 116 determines the first, second, and third closest base stations. The position of the mobile station 20 is determined based on the position of the station and the distance of the first closest base station (S314). When the specifying unit 114 can specify only the first and second closest base stations among the top six base stations, the position determining unit 116 determines the positions of the first and second closest base stations, The position of the mobile station 20 is determined based on the distance of the base station closest to the th (S316). When the specifying unit 114 can specify only the first closest base station among the top six base stations, the position determining unit 116 determines the position of the current mobile station 20 based on the position of the first closest base station. Is determined (S318). The position determination unit 116 may determine the position of the base station that is closest to the current position of the mobile station 20.

The position determining unit 116 determines the current position of the mobile station 20 and then determines the current position of the mobile station 20 based on the last four positions of the mobile station 20 (S320). The position determination unit 116 may determine the current position of the mobile station 20 by deriving the average of the positions of the last four mobile stations 20. The position determination unit 116 may determine the current position of the mobile station 20 by deriving a moving average of the positions of the mobile stations 20 in the past four times.

In FIG. 20, the base station 10-1, the second nearest base station 10-2, the third nearest base station 10-3, and the third nearest base station 10-3 are identified from the top six base stations. It is a figure for demonstrating the procedure which pinpoints the position of the mobile station 20 in the case of being. In this case, the position determination unit 116 has the base station 10 on the circumference 12-1 whose center is the position of the base station 10-1 and whose radius is the distance r derived from the received radio wave intensity of the base station 10-1. -2 closest to the point 13-1 (the point where the straight line connecting the base station 10-1 and the base station 10-2 intersects the circumference 12-1) and the base station 1-3 on the circumference 12-1 The intermediate point 14 on the arc between the point 13-2 closest to (a point where the straight line connecting the base station 10-1 and the base station 10-2 intersects the circumference 12-1) is Determine as position.

FIG. 21 shows the position of the mobile station 20 when only the base station 10-1 closest to the mobile station 20 and the second base station 10-2 closest to the mobile station 20 are specified among the top six base stations. It is a figure for demonstrating the procedure which pinpoints. The position determination unit 116 detects the base station 10-2 on the circumference 12-1 whose center is the position of the base station 10-1 and whose radius is a distance r derived from the received radio wave intensity of the base station 10-1. The closest point 14 (the point where the straight line connecting the base station 10-1 and the base station 10-2 and the circumference 12-1 intersect) is determined as the position of the mobile station 20.

FIG. 22 is a diagram for explaining a procedure for specifying the position of the mobile station 20 when only the base station 10-1 closest to the mobile station 20 is specified from among the six base stations. is there. In this case, the mobile station 20 may exist on the circumference 12-1 whose center is the position of the base station 10-1 and whose radius is the distance r derived from the received radio wave intensity of the base station 10-1. There is sex. However, since another base station 10 close to the mobile station 20 is not specified, the position determination unit 116 cannot specify one point on the circumference 12-1. Therefore, the position determination unit 116 determines the position of the base station 10-1 as the position of the mobile station 20.

Here, the mobile station 20 is a wireless terminal possessed by an employee who provides services to customers. Therefore, the position of the employee can be specified by the position of the mobile station 20 determined based on the received radio wave intensity by the procedure as described above. Based on the position of each mobile station 20 determined based on the received radio wave intensity, it is possible to grasp which table 80 each employee is staying in and which table 80 is not staying. That is, based on the position of each mobile station 20 determined based on the received radio wave intensity, it is possible to grasp whether each employee is in service or not. The behavior of each employee can be grasped from the position of each mobile station 20 determined based on the received radio wave intensity.

The base station information storage unit 132 may store, for example, position information of the partition 84 assigned to each of the plurality of tables 80 as shown in FIG. Then, the position determination unit 116 stays for at least a predetermined period based on the position of the mobile station 20 sequentially determined based on the strength information sequentially acquired by the strength information acquisition unit 102. It is determined whether there is a section 84 that is present. If the corresponding partition 84 exists, the position determination unit 116 determines that the mobile station 20 is staying in the table 80 assigned to the partition 84.

The procedure by which the position determination unit 116 identifies the table 80 where the mobile station 20 is staying is not limited to the above example. The position determination unit 116 determines that the mobile station 20 is the first base station when the first base station that has the maximum received radio wave intensity at the mobile station 20 exists in a predetermined period among the plurality of base stations 10. It may be determined that the user is staying in the first area associated with. When there is a first base station in which the received radio wave intensity at the mobile station 20 is greater than a predetermined value and is maximum among the plurality of base stations 10 during a predetermined period, the position determining unit 116 The mobile station 20 may determine that it is staying in the first area associated with the first base station. For example, if the base station with the highest received radio wave intensity at the mobile station 20 is the same for a predetermined period based on the intensity information sequentially acquired by the intensity information acquisition unit 102, the position determination unit 116 is the same. The mobile station 20 may determine that the mobile station 20 is staying in the table 80 assigned to the base station. For example, as illustrated in FIG. 24, the position determination unit 116 determines the base station (base station ID: 19) having the highest received radio wave intensity at the mobile station 20 specified based on the current intensity information, and the previous intensity. The base station (base station ID: 19) having the highest received radio wave intensity at the mobile station 20 identified based on the information is the same, and the received radio wave intensity is a predetermined value (eg, -100). In the case described above, it may be determined that the mobile station 20 is staying in the table 80 assigned to the base station (base station ID: 19).

Subsequently, employee management using the stay status of the mobile station 20 specified based on the received radio wave intensity at the mobile station 20 will be described.

The POS system 200 manages various pieces of information regarding the status of service provided to customers. For example, the POS system 200 uses the usage status of the table 80, the cleaning status of the table 80, whether or not there is an order from the customer, the time from when the table 80 is assigned to the customer until the order is received, the order contents of the customer, The database 202 manages the time from receipt of the payment to the completion of serving to the customer, the payment status of the customer, and the like.

Using such POS information, it is possible to provide better services to customers by giving appropriate notifications to appropriate employees. For example, in a restaurant such as a restaurant, a responsible employee may be assigned to each table 80. The quality of service can be improved by giving an appropriate instruction to the employee in charge in accordance with the service provision status. However, it is difficult to grasp the current employee behavior only with information managed by the POS system 200. For example, even if the time until the order is accepted has passed the allowable time, the employee may visit the customer's table 80 and give an order advice to the customer. Or, the employee may be serving customers at another table 80. In such a situation, it is not always optimal to notify the employee in charge of an instruction to ask for an order. Even after the allowable time allocated for a service has passed, the service is not necessarily provided because the employee does not notice it. In addition, if the employee in charge is a customer service but not another employee, it is possible to request the service of the customer on behalf of the employee in charge of the other employee to improve the quality of service to the customer. We can expect improvement.

Therefore, the employee management device 100 provides services to employees as appropriate via the mobile station 20 based on the stay information indicating the stay status of the table 80 of the mobile station 20 and the service information indicating the service provision status. A notification that prompts

In the employee management apparatus 100 shown in FIG. 7, the stay information storage unit 108 includes a region allocated to each mobile station 20 among a plurality of regions near any one of the plurality of base stations 10. The stay information indicating the identification information and the identification information of the area where each mobile station 20 is staying in association with the identification information of each mobile station 20 is stored. The stay information storage unit 108 includes a table ID of the table 80 assigned by each employee among the plurality of tables 80, and a table of the table 80 in which the mobile station 20 owned by each employee is staying. The stay information indicating the ID associated with the mobile station ID of each mobile station 20 is stored.

The generation unit 106 generates stay information based on the strength information. The generation unit 106 generates stay information based on the position of the mobile station 20 determined by the determination unit 110 from the intensity information. The generation unit 106 generates stay information according to the table 80 in which the mobile station 20 is staying, which is determined by the determination unit 110 based on the strength information.

The search unit 120 provides a predetermined service during a predetermined allowable time for a predetermined service based on the service provision status for each of the plurality of areas managed in the database 202. The first area that has not been searched is searched. Based on the service provision status with respect to each of the plurality of tables 80 managed in the database 202, the search unit 120 determines whether a predetermined service is provided during a predetermined allowable time for a predetermined service. A table 80 that is not provided is searched.

When the stay information does not indicate that the first mobile station assigned to the first area is staying in the first area, the instructing unit 122 notifies the first area to provide a predetermined service. The notification unit 124 is instructed to perform to the first mobile station. The instructing unit 122 does not indicate that the stay information indicates that an employee who is assigned as the person in charge of the table 80 for which the predetermined service is not provided even after the allowable time is staying in the table 80. In this case, the notification unit 124 is instructed to notify the mobile station 20 of the employee in charge that the service is provided for the table 80.

The notification unit 124 may notify the mobile station 20 of the employee in charge by transmitting a message prompting the provision of service. The notification unit 124 may perform the notification by transmitting a command to vibrate the mobile station 20 of the employee in charge to the mobile station 20.

The instructing unit 122 indicates that the stay information indicates that the first mobile station assigned to the first area where the service is to be provided is not staying in the first area and that the first mobile station is staying in another area. In the case where it is shown, the notification unit 124 may be instructed to notify another mobile station whose staying information is not indicated in the stay information among the plurality of areas. The instructing unit 122 confirms that the table 80 to be provided with the service is assigned as the person in charge, the employee's mobile station 20 is not staying at the table 80, and the mobile station 20 is staying at another table 80.

The instruction unit 122 refers to the stay information, specifies an employee to be notified, and instructs the notification unit 124 to notify the mobile station 20 of the employee of the message.

FIG. 26 is a flowchart showing an example of the stay information update procedure. The generation unit 106 updates the stay information for all employees to be managed with the stay information (S400). The generation unit 106 determines whether there is a table 80 in which the target employee is staying or which table 80 is in the staying table 80, based on the position of the mobile station 20 of the target employee by the determination unit 110. Judgment is made from the determination result (S402). If the generation unit 106 determines that the target employee is not staying in any table 80, the generation unit 106 updates the customer service information of the target employee to “Free” (S404).

If the target employee is staying in any of the tables 80, the generation unit 106 updates the customer service information of the target employee to the table ID of the staying table 80 (S406). Further, the generation unit 106 refers to the stay information stored in the stay information storage unit 108, and determines whether or not the employee stays for the first time after the customer is seated on the staying table 80 (S408). . The generation unit 106 may determine whether or not a responsible employee is assigned to the table ID of the table 80 in which the target employee is staying with reference to the stay information charge table. If the employee in charge is not yet assigned, the generation unit 106 registers the table 80 in which the target employee is staying as stay information of the target employee in the stay information (S410). Further, the generation unit 106 starts an order waiting monitoring timer of the staying table 80 in order to monitor the customer's order waiting (S412). If the time measured by the order waiting monitoring timer has passed a predetermined allowable time for order waiting and the order in the table 80 has not been received, the instruction unit 122 displays the employee in charge. The notification unit 124 may be instructed to prompt the mobile station 20 to request an order. On the other hand, if the employee in charge has already been assigned, the generation unit 106 ends the update process.

That is, the search unit 120 refers to the database 202 of the POS system 200 and acquires service information indicating the service provision status of the target table. The search unit 120 refers to the POS information and determines whether there is a service that is currently scheduled to be provided for the target table (S504). If there is a service scheduled to be provided, the search unit 120 determines whether or not the allowable time allocated to the service scheduled to be provided currently exceeds (S506). The POS system 200 may count the time until a service is provided with a timer for each service. The POS system 200 may store the allowable time for each service. The search unit 120 may acquire the POS information including the current time counted by the timer for the target service and the allowable time of the target service from the POS system 200. The search unit 120 may determine from the POS information whether the service allowable time is exceeded.

At this time, if the service allowable time is exceeded, the instruction unit 122 refers to the stay information and determines whether the employee in charge of the target table is currently staying in the target table (S508). If the target employee is not staying at the target table, the instruction unit 122 executes notification processing for the target table (S510). The POS system 200 repeats the process for all the tables 80 to be monitored (S512).

FIG. 28 is a flowchart illustrating an example of a notification instruction processing procedure by the instruction unit 122. The instruction unit 122 acquires the stay information of the employee in charge from the stay information storage unit 108 (S600). The instructing unit 122 refers to the stay information and determines whether or not the employee in charge is currently serving customers (S602). If the responsible employee is not currently serving customers, the instruction unit 122 instructs the notification unit 124 to notify the mobile station 20 of the responsible employee in order to instruct immediate service provision to the target table of the responsible employee ( S604).

If the employee in charge is currently in service, the instruction unit 122 notifies the notification unit 124 to the mobile station 20 of the employee in charge in order to instruct the employee in charge to provide a service for the target table after completion of the current customer service. An instruction is given (S606).

The instruction unit 122 starts an elapsed time count timer after instructing the notification to the notification unit 124 (S608). When the count by the elapsed time count timer has passed the standby period, the instruction unit 122 refers to the POS information provided from the POS system 200 and determines whether the provision of the target service is completed (S610). ). If the provision of the target service has not been completed, the instructing unit 122 refers to the stay information and instructs an employee who does not have a staying table among the non-responsible employees to provide immediate service for the target table. Accordingly, the notifying unit 124 is instructed to notify the mobile station 20 of other employees who do not have a staying table, that is, are not currently serving customers (S612).

FIG. 29 is a flowchart illustrating an example of a notification instruction processing procedure by the instruction unit 122. The instruction unit 122 acquires the stay information of the employee in charge from the stay information storage unit 108 (S700). The instructing unit 122 refers to the stay information and determines whether or not the employee in charge is currently serving customers (S702). If the responsible employee is not currently serving customers, the instruction unit 122 instructs the notification unit 124 to notify the mobile station 20 of the responsible employee in order to instruct immediate service provision to the target table of the responsible employee ( S704).

If the employee in charge is currently serving customers, the instruction unit 122 determines whether notification instructions can be sequentially issued for all employees who can provide services in order to identify employees who are not currently serving customers (S706). The instructing unit 122 refers to the stay information to determine whether another target employee is currently serving customers (S708). If another target employee is currently in service, the instruction unit 122 determines whether another employee is currently in service (S712).

If other employees of the target who are not serving customers are found, the instruction unit 122 instructs the notification unit 124 to provide the mobile station 20 of the other employees of the target in order to provide immediate service to the other employees of the target. Is notified (S710).

As described above, if there is a service that has not been completed even after the allowable time has passed, the customer service is completed so that the service is completed according to the customer service status of the employee in charge and the customer service status of other employees. Appropriate notifications can be made to employees who can. Therefore, useless instructions are not given to employees, service provision can proceed smoothly, and service quality can be improved.

】 A more specific service will be described as an example. The POS system 200 manages the order reception status of each of a plurality of areas as a service provision status in the database 202. The search unit 120 may search a region that has not received an order during a predetermined allowable time as the first region. The POS system 200 manages the order acceptance status of each of the plurality of tables 80 as a service provision status in the database 202. The search unit 120 may search the table 80 to be notified of a table 80 that has not received an order during a predetermined allowable time. The order acceptance status may indicate the time when the order can be accepted and whether or not the order has been accepted. The time when the order can be received is the time when the table 80 is assigned to the customer, the time assigned to the employee in charge of the table 80, and the time when the first employee stays in the table 80 of the new customer. Good.

FIG. 30 is a flowchart showing an example of an order waiting time monitoring procedure. The search unit 120 repeats this monitoring procedure for all the tables 80 to be monitored (S800). The search unit 120 acquires order status information from the POS system 200. The order status information includes the time at which the employee is assigned as the person in charge of the table 80 (the time when the employee is registered in the person in charge table in the stay information), the order information indicating the order item ordered by the customer, and the time at which the order is placed. . The search unit 120 refers to the order status information and determines whether there is order information corresponding to the target table (S804).

If there is no order information, the instructing unit 122 determines whether or not the order waiting monitoring timer has exceeded the allowable time for inquiring about orders (S806). The order waiting monitoring timer is, for example, a timer that starts counting from the time when the employee is assigned as the person in charge of the table 80. If the instruction allowable time is exceeded, the instructing unit 122 refers to the stay information and determines whether the employee in charge of the target table is currently staying in the target table (S810). If the employee in charge is not staying at the target table, the instructing unit 122 executes processing for instructing an order for the target table (S812).

On the other hand, if there is order information, the order waiting monitoring timer and the elapsed time counter timer that starts counting when an order inquiry instruction is given to the employee are cleared (S814).

The instruction unit 122 repeats the processing from step S802 on all the monitored tables 80.

If the employee in charge is not currently in customer service, the instruction unit 122 instructs the notification unit 124 to notify the employee in charge of the mobile station 20 of an immediate order for the target table. S904).

If the responsible employee is currently in service, the instruction unit 122 notifies the responsible employee's mobile station 20 to notify the responsible employee of ordering for the target table after the current customer service is completed. The unit 124 is instructed (S906).

The instruction unit 122 starts an elapsed time count timer after instructing the notification unit 124 (S908). The instructing unit 122 further refers to the order status information provided from the POS system 200 and determines whether or not there is order information in the target table before the elapsed time count timer exceeds a predetermined waiting period. (S910). If there is no order information in the target table even if the count of the elapsed time count timer exceeds a predetermined waiting period, the instruction unit 122 refers to the stay information, and the table being stayed among the non-charged employees is The notification unit 124 is instructed to notify the other employee's mobile station 20 of an order to inquire about the order to the target table to other non-employees (S912).

As described above, when an order is not received from a customer within a predetermined allowable time, there is a possibility that an employee forgets to ask for an order on the table 80 and the customer cannot place an order. Therefore, when such a situation occurs, the ordering instruction is notified to the mobile station 20 of the employee in charge. If an order for the target table is not received even after the instruction to ask the mobile station 20 to order the mobile station 20, the mobile stations of employees who are not currently serving customers among employees other than the employee in charge are not accepted. 20 is further notified of an order inquiry instruction. As a result, it is possible to prevent the customer from placing an order and waiting, and to improve the quality of service.
