2. Description of the Related Art Conventionally, there has been known a work management system including a worker terminal, a management device, a relay device, and an administrator terminal (see, for example, Japanese Patent Application Laid-Open No. 2003-233664).
The worker terminal was equipped with an environmental sensor that acquired work environment information related to the environment surrounding the worker terminal, a work information acquisition means that acquired work information related to the work status of the worker carrying the worker terminal, and a notification means that notifies the work environment information acquired by the environmental sensor and the work information acquired by the work information acquisition means.

JP 2018-36985 A (see especially paragraphs 0011 and 0037)

However, the conventional work management systems described above were configured such that the user, who is the worker, carried a worker terminal, work information was notified by a notification means, and the notification means was used to notify when something occurred. This caused the problem that it was difficult to easily manage attendance records for coming to and leaving work without user operation or with reduced operation.

Therefore, the present invention is intended to solve the problems of the prior art as described above. In other words, the object of the present invention is to provide an attendance management system and an attendance management system program that easily manages attendance when arriving at and leaving work without any user operation or with reduced operation.

The invention according to claim 1 is an attendance management system comprising a beacon installed indoors and emitting a predetermined radio wave, a user portable mobile terminal capable of communicating with the beacon, a server capable of communicating with the user portable mobile terminal, and an administrator terminal capable of communicating with the server, wherein the beacons are installed separately in a predetermined area at an entrance to the indoors, and when the user portable mobile terminal is receiving radio waves from a plurality of beacons, the user portable mobile terminal or the server switches the apparent frequency of the received radio waves from the outer beacon closer to the entrance from an increased state to a decreased state based on the beacon radio wave reception status from those beacons, and the strength of the received radio waves from the outer beacon closer to the entrance As the apparent frequency of the received radio waves from the inner beacons farther from the entrance/exit changes from a gradually increasing tendency to a gradually decreasing tendency, the apparent frequency of the received radio waves from the inner beacons farther from the entrance/exit changes from an increased state to a decreased state, and as the intensity of the received radio waves from the inner beacons farther from the entrance/exit changes from a gradually increasing tendency to a gradually decreasing tendency, the apparent frequency of the received radio waves from the inner beacons farther from the entrance/exit changes from an increased state to a decreased state, and as the intensity of the received radio waves from the inner beacons farther from the entrance/exit changes from a gradually increasing tendency to a gradually decreasing tendency, the apparent frequency of the received radio waves from the outer beacons closer to the entrance/exit changes from a decreased state to a decreased state. When the state of the received radio waves from a plurality of beacons changes to one in which the strength of the received radio waves from the inner beacons farther from the entrance/exit changes gradually, it is determined that the movement is in the direction of entering the room. On the other hand, when the apparent frequency of the received radio waves from the inner beacons farther from the entrance/exit changes from an increased state to a decreased state and the strength of the received radio waves from the inner beacons farther from the entrance/exit changes from a gradually increased to a gradually weakened state, it is determined that the movement is in the direction of entering the room. When the situation of received radio waves from multiple beacons changes to a situation where the apparent frequency of the waves switches from an increased state to a decreased state and the strength of the received radio waves from the outer beacons closer to the entrance/exit switches from a gradually increasing trend to a gradually decreasing trend, while the apparent frequency of the received radio waves from the inner beacons farther from the entrance/exit remains in a decreased state and the strength of the received radio waves from the inner beacons farther from the entrance/exit remains gradually weakening, it is determined that the movement is in the direction of leaving the room, and the server is configured to record information about the movement in the direction of entering or leaving the room in a database together with user name information and date and time information , thereby solving the above-mentioned problem.

As the strength of the received radio waves from the beacons on the inner side farther from the entrance/exit switch from a gradually increasing trend to a gradually decreasing trend, the apparent frequency of the received radio waves from the beacons on the inner side farther from the entrance/exit remains increased, and the strength of the received radio waves from the beacons on the inner side farther from the entrance/exit switch from a gradually increasing trend to a gradually decreasing trend, and the apparent frequency of the received radio waves from the beacons on the inner side farther from the entrance/exit switch from an increased state to a decreased state, and as the strength of the received radio waves from the beacons on the inner side farther from the entrance/exit switch from a gradually increasing trend to a gradually decreasing trend, the apparent frequency of the received radio waves from the beacons on the outer side closer to the entrance/exit remains decreased, and When the state of the received radio waves from a plurality of beacons changes to one in which the strength of the received radio waves from the beacons continues to gradually weaken, it is determined that the movement is in the direction of entering the room. On the other hand, when the apparent frequency of the received radio waves from the beacons on the inner side, which is farther from the entrance/exit, changes from an increased state to a decreased state, and the strength of the received radio waves from the beacons on the inner side, which is farther from the entrance/exit, changes from a gradually increasing tendency to a gradually weakening tendency, in which the apparent frequency of the received radio waves from the beacons on the outer side, which is closer to the entrance/exit, remains increased, and the strength of the received radio waves from the beacons on the outer side, which is closer to the entrance/exit, continues to gradually strengthen, the apparent frequency of the received radio waves from the beacons on the outer side, which is closer to the entrance/exit, remains increased, When the state of the received radio waves from a plurality of beacons changes to a state in which the apparent frequency of the received radio waves from the inner beacons farther from the entrance/exit remains in a decreasing state and the strength of the received radio waves from the inner beacons farther from the entrance/exit remains gradually weaker as the frequency switches from an increasing state to a decreasing state and the strength of the received radio waves from the outer beacons closer to the entrance/exit switches from a gradually increasing trend to a gradually weakening trend, the above-mentioned problem is solved by comprising a movement direction determination step of determining that the movement is in the direction of leaving the room, and a recording step in which the server records information about the movement in the direction of entering or leaving the room together with user name information and date and time information in a database.

The attendance management system of the present invention comprises a beacon installed indoors and emitting specified radio waves, a user portable mobile terminal capable of communicating with the beacon, a server capable of communicating with the user portable mobile terminal, and a location display terminal capable of communicating with the server, thereby not only enabling the user portable mobile terminal to receive radio waves from the beacon, but also achieving the following unique effects.

A location confirmation system 100 according to a first embodiment of the present invention will be described below with reference to FIGS. 1 to 5B.
Here, Figure 1 is a diagram showing the concept of location confirmation system 100, which is a first embodiment of the present invention, Figure 2 is a chart diagram showing an example of the operation of location confirmation system 100, which is the first embodiment of the present invention, Figure 3 is a diagram showing an example of user-specific display on location information display screen 142 of location confirmation system 100, which is the first embodiment of the present invention, Figure 4 is a diagram showing an example of floor-specific display on location information display screen 142 of location confirmation system 100, which is the first embodiment of the present invention, Figure 5 (A) is a diagram showing an example of notification setting screen 144 of location confirmation system 100, which is the first embodiment of the present invention, and Figure 5 (B) is a diagram showing an example of notification by mail browser 145.

As shown in FIG. 1, the location confirmation system 100 according to the first embodiment of the present invention includes a beacon 110, a smartphone terminal 120 which is an example of a user portable mobile terminal, a server 130, and a computer terminal 140 which is an example of a location display terminal.
Of these, the beacon 110 is installed indoors and is configured to emit a predetermined radio wave.

For example, three beacons 110 are installed separately on a floor FL of a specific room inside a specific building BD.
The smartphone terminal 120 is also provided so as to be able to communicate freely with the beacon 110 via short-range wireless communication means.
Furthermore, the server 130 is provided so as to be able to communicate freely with the user's smartphone terminal 120 .
Further, the computer terminal 140 is provided so as to be able to communicate freely with the server 130 .

In this embodiment, when the user's smartphone terminal 120 is receiving radio waves from the beacon 110 , it transmits the beacon radio wave reception status from the beacon 110 to the server 130 .
The server 130 then estimates the current location of the user's smartphone terminal 120 within the specified indoor area based on the beacon radio wave reception status from that beacon 110 .
Then, the estimated current location information of the user's smartphone terminal 120 is registered in the database 131 of the server 130.
Here, the radio waves of the beacons 110 are different for each beacon 110, and each beacon 110 is configured to emit a unique radio wave.
The unique radio wave may have a different wavelength, frequency, or amplitude, or may include a unique signal every predetermined second.

It is also assumed that information on the installation location of each beacon 110 is registered in server 130 of position confirmation system 100 .
Therefore, when the user's smartphone terminal 120 receives radio waves from the beacon 110, the position of the user's smartphone terminal 120 can be estimated.
For example, when radio waves from one beacon 110 are being received, it can be estimated that the position of the user's smartphone terminal 120 is in the vicinity of that beacon 110 .
The distance from the beacon 110 may be estimated based on the strength of the received radio wave (received strength divided by transmitted strength) or may be determined based on the phase difference of the radio wave.
Furthermore, by registering (setting) the position of the beacon 110 in advance, it is possible to estimate the relative position, which is the relative coordinates of the user's smartphone terminal 120 with respect to the position of the beacon 110.
In addition, when radio waves from two beacons 110 are being received, the position of the user's smartphone terminal 120 is one of two positions determined by the distance from the two beacons 110 based on the strength of the received radio waves or the phase difference of the radio waves.

Furthermore, when radio waves from three or more beacons 110 are being received, the position of the user's smartphone terminal 120 is determined by the distance from the three or more beacons 110 based on the strength of the received radio waves or the phase difference of the radio waves.
Regarding the estimation or identification of the location of the user's smartphone terminal 120, the configuration may be such that the user's smartphone terminal 120 estimates or identifies the location and transmits the location information to the server 130, or the configuration may be such that the user's smartphone terminal 120 transmits the radio wave reception conditions to the server 130 and the server 130 estimates or identifies the location.

Furthermore, the browser 141 of the computer terminal 140 is configured to communicate with the server 130 and display location information of the user's smartphone terminal 120 estimated based on the beacon radio wave reception status of the user's smartphone terminal 120.
As a result, location information of the user's smartphone terminal 120 estimated based on the beacon radio wave reception status of the user's smartphone terminal 120 is collected by the server 130 and displayed on the browser 141 of the computer terminal 140.
As a result, the administrator can easily grasp the current location of the user within a specific indoor area.
Furthermore, when the user enters a specified indoor location, location information of the user's smartphone terminal 120 estimated based on the beacon radio wave reception status of the user's smartphone terminal 120 is displayed on the browser 141 of the computer terminal 140.
As a result, the administrator can easily manage the users' attendance by recording the reception log from the user's smartphone terminal 120 to the server 130.

The operation of the location system 100 will now be described in more detail.
As shown in FIG. 2, in step S1, as a reception determination step, it is determined whether or not the smartphone terminal 120 of the user is receiving radio waves from the beacon 110.
If it is determined that the signal has been received, the process proceeds to step S2. On the other hand, if it is determined that the signal has not been received, step S1 is repeated.

In step S2, as a transmission step, the user's smartphone terminal 120 transmits the beacon radio wave reception status from the beacon 110 to the server 130.
Then, as a position estimation step, the server 130 estimates the current position of the user's smartphone terminal 120 within a specific indoor location based on the beacon radio wave reception status from the beacon 110 .
As mentioned above, the user's smartphone terminal 120 may be configured to estimate or identify the current location based on the radio waves received from the beacon 110 and transmit the location information to the server 130, or the user's smartphone terminal 120 may transmit the beacon radio wave reception status to the server 130, and the server 130 may estimate or identify the location.
In other words, either immediately before or after the transmission step S2, as a position estimation step S2, the user's smartphone terminal 120 or the server 130 estimates the current position of the user's smartphone terminal 120 within a specified room based on the beacon radio wave reception status from the beacon 110.

In step S3, as a display step, the browser 141 of the computer terminal 140 communicates with the server 130 and displays the location information of the user's smartphone terminal 120 estimated based on the beacon radio wave reception status of the user's smartphone terminal 120.
As an example, as shown in FIG. 3, a browser 141 of a computer terminal 140 displays a location information display screen 142 .

For example, the user's boss, colleagues, subordinates, etc. log into the location confirmation system 100 using a computer terminal 140 .
In response to this, the browser 141 of the computer terminal 140 is configured to display a position information display screen 142 .
The location information display screen 142 is provided with a department item that allows the user to freely select a department, a name item that allows the user to freely display members of the selected department, and a location display item that displays the floor.

Then, when the operator of computer terminal 140 selects, for example, "Development Division 1" in the department item, the names of the members of "Development Division 1" are displayed in the name item.
Furthermore, for example, when "Tanaka Jiro" is selected in the name field, the location display field is configured to display, as an example, the 5th floor of the head office based on the location information of Tanaka Jiro's smartphone terminal 120 registered in database 131 of server 130, and to display the current location information of Tanaka Jiro's smartphone terminal 120 on the 5th floor of the head office using pin 143.

Furthermore, in this embodiment, there are a plurality of beacons 110, which are installed on different floors FL within a specific room, or on a plurality of floors FL within a specific room.
This identifies which of a plurality of floors FL within a given room the user's smartphone terminal 120 is on depending on which beacon 110 the user's smartphone terminal 120 is receiving radio waves from.
As a result, the administrator can easily grasp the current location of the user within a specific building, even if the location is over a wide area spanning multiple floors FL.

In this embodiment, three or more beacons 110 are installed separately from each other on one floor FL in a specific room.
This allows the positional relationship between the user's smartphone terminal 120 and three or more beacons 110 to be identified based on the strength of radio waves received from the three or more beacons 110 or the phase difference of the received radio waves.
As a result, even if one floor FL is large, the administrator can easily grasp the current location of the user on that floor FL.

Furthermore, in this embodiment, the position information display screen 142 is provided with a floor selection button.
When the operator clicks the floor selection button, each floor of each facility where the beacon 110 is installed is displayed as an item in a pull-down menu format.
Then, when the operator selects "5th floor of head office" as an example, the current location information of the smartphone terminals 120 of all users receiving radio waves from the beacon 110 on the 5th floor of the head office is displayed together with their user name information.
This allows the operator to easily check who is on the selected floor.
Plus, you can easily see who's with who.

Also, in this embodiment, as shown in FIG. 5 (A), in the notification setting screen 144 displayed on the browser 141 of the computer terminal 140, which is an example of a location display terminal, the smartphone terminal 120 of a specific user, the floor where the specific beacon 110 is installed, and the computer terminal 140 where the specified input was made or the terminal of the user to be notified can be freely specified.
In other words, the three parties can be freely specified: "When Mr./Ms. XX comes to the △△ area, notify Mr./Ms. XX."
For example, suppose that it is specified that if "Nakamura Rosa" comes to the "5th floor of the head office", then "Tanaka Jiro" is to be notified.

When the smartphone terminal 120 of "Nakamura Rosa" receives radio waves from the beacon 110 installed on the "5th floor of the head office," the smartphone terminal 120 transmits the beacon radio wave reception status from that beacon 110 to the server 130.
The server 130 then receives information about the smartphone terminal 120 of "Nakamura Rosa", a specific user specified by the computer terminal 140, and the beacon 110 of "Head office 5th floor", a specific beacon 110.

Then, the server 130 determines whether the beacon radio wave reception status from the beacon 110 on the specified "5th floor of the head office" has been received from the smartphone terminal 120 of the specified user, "Nakamura Rosa."
When received, server 130 is configured to notify computer terminal 140, which is an example of a location display terminal from which the specified input was made, or computer terminal 140 of the specified user "Tanaka Jiro," that "Nakamura Rosa," the user of smartphone terminal 120 of the specified user "Nakamura Rosa," is in the "5th floor of the head office," which is the area where the specified beacon 110 is installed.

As a result, as shown in FIG. 5B, the mail browser 145 on Mr. "Tanaka Jiro's" computer terminal 140 receives a message from the server 130, and is notified when "Nakamura Rosa" arrives at or returns to the "5th floor of the head office."
As a result, "Tanaka Jiro" can easily know when "Nakamura Rosa" has arrived at or returned to the "5th floor of the head office."
Although email is used as an example of the notification method, notification in text format via chat using a chat application or notification in voice format via telephone may also be used.

The position confirmation system 100, which is the first embodiment of the present invention obtained in this way, includes a beacon 110 installed in a specified room and emitting a specified radio wave, a smartphone terminal 120 which is an example of a user portable mobile terminal that can communicate with the beacon 110, a server 130 which can communicate with the user's smartphone terminal 120, and a computer terminal 140 which is an example of a position display terminal that can communicate with the server 130. When the user's smartphone terminal 120 receives radio waves from the beacon 110, the user's smartphone terminal 120 or the server 130 estimates the current position of the user's smartphone terminal 120 in the specified room based on the beacon radio wave reception status from the beacon 110, and the browser 141 of the computer terminal 140 communicates with the server 130 to display the position information of the user's smartphone terminal 120 estimated based on the beacon radio wave reception status of the user's smartphone terminal 120. This allows the administrator to easily grasp the current location of the user in the specified room, and the administrator can easily manage the user's attendance by recording the reception log from the user's smartphone terminal 120 to the server 130.

Furthermore, since there are multiple beacons 110 and they are installed on different floors FL within a specific room, or on multiple floors FL within a specific room, the administrator can easily grasp the current location of the user within the specific room, even if it is over a wide area that spans multiple floors FL.

In addition, by configuring three or more beacons 110 to be installed at different locations on one floor FL within a given room, an administrator can easily grasp the current location of a user on that floor FL even if the floor FL is large.

Furthermore, when a specific user's smartphone terminal 120 and a specific beacon 110 are specified on the computer terminal 140, the server 130 receives information about the specified user's smartphone terminal 120 and the specific beacon 110 from the computer terminal 140, and when it receives from the specified user's smartphone terminal 120 that it is receiving information from the specified specific beacon 110, it notifies the computer terminal 140 from which the specification was made or the specified terminal (140) that the user of the specified user's smartphone terminal 120 is in the area where the specific beacon 110 is installed, so that the administrator and other users can easily know that a user they want to meet has arrived or returned to the area.

The program of the location confirmation system 100, which is the first embodiment of the present invention, includes a reception determination step S1 for determining whether the user's smartphone terminal 120 is receiving radio waves from the beacon 110, a position estimation step S2 for the user's smartphone terminal 120 or the server 130 estimating the current position of the user's smartphone terminal 120 within a specified room based on the beacon radio wave reception status from the beacon 110 when the radio waves are being received, and a display step S3 for the browser 141 of the computer terminal 140 communicating with the server 130 to display the location information of the user's smartphone terminal 120 estimated based on the beacon radio wave reception status of the user's smartphone terminal 120. This allows the administrator to easily grasp the current location of the user within a specified room, and the administrator can easily manage the user's attendance by recording the reception log from the user's smartphone terminal 120 to the server 130, which has a significant effect.

Next, a second embodiment of the attendance management system 200 according to the present invention will be described with reference to FIGS.
Here, Figure 6 is a diagram showing the concept of the attendance management system 200 which is the second embodiment of the present invention, Figure 7 is a chart showing an example of the operation of the attendance management system 200 which is the second embodiment of the present invention, and Figure 8 is a diagram showing an example of the attendance display screen 242 of the attendance management system 200 which is the second embodiment of the present invention.
The attendance management system 200 of the second embodiment manages attendance by determining the direction of movement instead of estimating location information as in the location confirmation system 100 of the first embodiment, and since it has many elements in common with the location confirmation system 100 of the first embodiment, detailed explanations of the common points will be omitted and only a number in the 200 range with the last two digits being used.

As shown in FIG. 6, the second embodiment of the attendance management system 200 of the present invention includes a beacon 210, a smartphone terminal 220 which is an example of a user portable mobile terminal, a server 230, and a computer terminal 240 which is an example of an administrator terminal.
Of these, the beacons 210 are installed at a distance from each other in a predetermined area AR at an entrance/exit of a predetermined room, for example, two beacons 210 .
The installation positions of the two beacons 210 need only be apart from each other within the specified area AR at least in the direction in which the user passes through the entrance/exit, because the received radio waves can be distinguished between when the user is moving in the direction of entering the room and when the user is moving in the direction of leaving the room.

When the user's smartphone terminal 220 is receiving radio waves from two beacons 210, it determines whether the user is moving in the direction of entering or leaving the room based on the beacon radio wave reception conditions from those beacons 210 (strength of the received radio waves, phase difference of the received radio waves, changes in strength of the received radio waves, and changes in apparent frequency), and transmits information indicating entry or exit to the server 230.
Furthermore, the server 230 is configured to record information regarding movement in the direction of entering or moving in the direction of leaving the room received from the user's smartphone terminal 220 in the database 231 together with user name information and date and time information.
Regarding the determination of the movement direction of the user's smartphone terminal 220, the user's smartphone terminal 220 may determine and transmit information on the movement direction to the server 230, or the user's smartphone terminal 220 may transmit the beacon radio wave reception status to the server 230, and the server 230 may determine the direction based on the beacon radio wave reception status received.

This determines whether the movement is in the direction of entering or leaving the room based on the beacon radio wave reception status from multiple beacons 210, and records the user name information and date and time information, eliminating the need for bothersome time card operations.
As a result, convenience for users is improved and the manager can easily manage the attendance records of each user using the manager's computer terminal 240 .

Next, the operation of the attendance management system 200 will be described in more detail.
As shown in FIG. 7, in step S11, a reception determination step, it is determined whether the user's smartphone terminal 220 is receiving radio waves from two beacons 210 installed separately in a specified area AR at an entrance/exit of a specified indoor area.
If it is determined that the signal has been received, the process proceeds to step S12, whereas if it is determined that the signal has not yet been received, step S11 is repeated.

In step S12, which is a movement direction determination step, the user's smartphone terminal 220 determines whether the movement is in the direction of entering or leaving the room based on the beacon radio wave reception conditions from the two beacons 210.
For example, when a user enters a room, the user moves toward both of the two beacons 210, one closer to the entrance (outer side) and the other farther from the entrance (inner side).
When the user moves in the direction of entering the room, he/she passes the position of the beacon 210 closer to the entrance/exit (closer to the outside), and from the moment the user's smartphone terminal 220 passes the position of the beacon 210 closer to the entrance/exit (closer to the outside), it moves away from the beacon 210 closer to the entrance/exit (closer to the outside).
That is, for the beacon 210 closer to the entrance (closer to the outside), the movement is away, and for the beacon 210 farther from the entrance (closer to the inside), the movement remains approaching.
At this time, the apparent frequency of the received radio waves from the beacon 210 closer to the entrance/exit (outer side) switches from an increased state to a decreased state, and the strength of the received radio waves from the beacon 210 closer to the entrance/exit (outer side) switches from a gradually increasing tendency to a gradually decreasing tendency.
In addition, the apparent frequency of the received radio waves from the beacons 210 farther from the entrance/exit (closer to the inside) remains increased, and the strength of the received radio waves from the beacons 210 farther from the entrance/exit (closer to the inside) continues to tend to gradually increase.

Furthermore, when the user moves in the direction of entering the room, he/she passes the position of the beacon 210 farther from the entrance/exit (closer to the inside), and from the moment the user's smartphone terminal 220 passes the position of the beacon 210 farther from the entrance/exit (closer to the inside), it moves away from the farther (closer to the inside) beacon 210.
That is, the beacon 210 moves away from both the beacon 210 closer to the entrance (outside) and the beacon 210 farther from the entrance (inside).
At this time, the apparent frequency of the received radio waves from the beacon 210 farther from the entrance/exit (closer to the inside) switches from an increased state to a decreased state, and the strength of the received radio waves from the beacon 210 farther from the entrance/exit (closer to the inside) switches from a gradually increasing tendency to a gradually decreasing tendency.
In addition, the apparent frequency of the received radio waves from the beacon 210 closer to the entrance/exit (outside) remains decreased, and the strength of the received radio waves from the beacon 210 closer to the entrance/exit (outside) continues to tend to gradually weaken.
In this way, the state of the received radio waves from the two beacons 210 switches, and the moving direction of the user's smartphone terminal 220 is determined to be the direction of entering the room.

On the other hand, when the user leaves the room, the user moves toward both of the two beacons 210, one closer to the entrance (outer side) and the other farther from the entrance (inner side).
When the user moves in the direction of leaving the room, he/she passes the position of the beacon 210 farther from the entrance/exit (closer to the inside), and from the moment the user's smartphone terminal 220 passes the position of the beacon 210 farther from the entrance/exit (closer to the inside), it moves away from the beacon 210 farther from the entrance/exit (closer to the inside).
That is, for the beacon 210 that is farther from the entrance (closer to the inside), the movement is away, and for the beacon 210 that is closer to the entrance (closer to the outside), the movement remains approaching.
At this time, the apparent frequency of the received radio waves from the beacon 210 farther from the entrance/exit (closer to the inside) switches from an increased state to a decreased state, and the strength of the received radio waves from the beacon 210 farther from the entrance/exit (closer to the inside) switches from a gradually increasing tendency to a gradually decreasing tendency.
In addition, the apparent frequency of the received radio waves from the beacon 210 closer to the entrance/exit (closer to the outside) remains increased, and the strength of the received radio waves from the beacon 210 closer to the entrance/exit (closer to the outside) continues to tend to gradually increase.

Furthermore, when the user moves in the direction of leaving the room, he/she passes the position of the beacon 210 closer to the entrance/exit (closer to the outside), and from the moment the user's smartphone terminal 220 passes the position of the beacon 210 closer to the entrance/exit (closer to the outside), it moves away from the closer (closer to the outside) beacon 210.
In other words, the beacon 210 closer to the entrance (closer to the outside) and the beacon 210 farther from the entrance (closer to the inside) are moved away from each other.
At this time, the apparent frequency of the received radio waves from the beacon 210 closer to the entrance/exit (outer side) switches from an increased state to a decreased state, and the strength of the received radio waves from the beacon 210 closer to the entrance/exit (outer side) switches from a gradually increasing tendency to a gradually decreasing tendency.
In addition, the apparent frequency of the received radio waves from the beacons 210 farther from the entrance/exit (closer to the inside) remains decreased, and the strength of the received radio waves from the beacons 210 farther from the entrance/exit (closer to the inside) continues to tend to gradually weaken.
In this way, the state of the received radio waves from the two beacons 210 switches, and the moving direction of the user's smartphone terminal 220 is determined to be the direction toward leaving the room.

In step S13, as a transmission step, the user's smartphone terminal 220 transmits, to the server 230, information on movement in the direction of entering or leaving the room.
As mentioned above, the movement direction of the user's smartphone terminal 220 may be determined by the user's smartphone terminal 220 and transmit information on the movement direction to the server 230, or the user's smartphone terminal 220 may transmit a beacon radio wave reception status to the server 230 and the server 230 may make a determination based on the beacon radio wave reception status received.
In other words, steps S12 and S13 may be reversed.
In step S14, as a recording step, the server 230 records the information on movement in the direction of entering or moving in the direction of leaving the room received from the user's smartphone terminal 220 in the database 231 together with the user name information and date and time information.

As a result, as described above, based on the beacon radio wave reception status from multiple beacons 210, it is determined whether the movement is in the direction of entering or leaving the room, and this is recorded together with the user name information and date and time information, eliminating the need for cumbersome time card operations.
As a result, convenience for users is improved and the manager can easily manage the attendance records of each user using the manager's computer terminal 240 .
For example, as shown in FIG. 8, when a manager logs in to the attendance management system 200 using a computer terminal 240 , a browser 241 of the manager's computer terminal 240 displays an attendance display screen 242 .
As an example, the attendance display screen 242 has a department field that allows the user to freely select the department, a name field that allows the user to freely display members of the selected department, a user-specific display field that indicates the display target, a date field, an arrival time field, a departure time field, and a return time from leaving the office field.

Then, when the administrator selects, for example, "Development Division 1" in the department item, the names of the members of "Development Division 1" are displayed in the name item.
Furthermore, for example, when "Tanaka Jiro" is selected in the name field, the user-specific display field representing the display target displays the name "Tanaka Jiro," and the date field, arrival time at work field, departure time field, departure time field, and return time from leaving field are configured to display the attendance information of "Tanaka Jiro" based on, for example, the entry/exit information, which is the direction of movement of Tanaka Jiro's smartphone terminal 220, and the date and time information registered in the database 231 of the server 230.

The attendance display screen 242 is provided with a display switching button, and is configured to be freely switched between a user-based display and a weekly/monthly display.
The user-specific display is provided to display attendance information for each user.
The weekly and monthly displays are designed to display attendance information for a specified week or month.

The attendance management system 200, which is the second embodiment of the present invention obtained in this way, includes a beacon 210 installed in a specified room and emitting a specified radio wave, a smartphone terminal 220 which is an example of a user's portable mobile terminal that can communicate with the beacon 210, a server 230 which can communicate with the user's smartphone terminal 220, and a computer terminal 240 which is an example of an administrator terminal that can communicate with the server 230. The beacons 210 are installed separately in a specified area AR at the entrances and exits of the specified room, and when the user's smartphone terminal 220 receives radio waves from the multiple beacons 210, the user's smartphone terminal 220 or the server 230 determines whether the movement is in the direction of entering or leaving the room based on the beacon radio wave reception status from the beacons 210, and the server 230 records information on the movement in the direction of entering or leaving the room together with user name information and date and time information in the database 231. This configuration increases the convenience of the user and allows the administrator to easily manage the attendance of each user's arrival and departure using the administrator's computer terminal 240.

The program of the attendance management system 200, which is the second embodiment of the present invention, includes a reception determination step S11 for determining whether the user's smartphone terminal 220 is receiving radio waves from multiple beacons 210 installed separately in a specified area AR at the entrances and exits of a specified room, a movement direction determination step S12 for the user's smartphone terminal 220 or the server 230 for determining whether the movement is in the direction of entering or leaving the room based on the beacon radio wave reception status from those beacons 210 when the radio waves are being received, and a recording step S14 for the server 230 for recording information on the movement in the direction of entering or leaving the room together with the user name information and date and time information in the database 231. This increases the convenience for users and allows the administrator to easily manage the attendance of each user's arrival and departure using the administrator's computer terminal 240, and has a significant effect.

Next, a attendance management system 300 according to a third embodiment of the present invention will be described with reference to FIGS.
Here, Figure 9 is a diagram showing the concept of the attendance management system 300 which is the third embodiment of the present invention, Figure 10 is a chart showing an example of the operation of the attendance management system 300 which is the third embodiment of the present invention, and Figure 11 is a diagram showing an example of the attendance menu screen 321 displayed on the smartphone terminal 320 of the attendance management system 300 which is the third embodiment of the present invention.
The attendance management system 300 of the third embodiment manages attendance by recording attendance information through input operations on the attendance menu screen 321 instead of determining the direction of movement as in the attendance management system 200 of the second embodiment, and since many elements are common to the location confirmation system 100 of the first embodiment and the attendance management system 200 of the second embodiment, detailed explanations of the common points will be omitted and only a number in the 300 range with the last two digits being common will be used.

As shown in FIG. 9, the attendance management system 300 according to the third embodiment of the present invention includes a beacon 310, a smartphone terminal 320 which is an example of a user portable mobile terminal, a server 330, and a computer terminal 340 which is an example of an administrator terminal.
Of these, one beacon 310 is installed in a predetermined area AR at an entrance/exit of a predetermined indoor space.

In this embodiment, when the user's smartphone terminal 320 receives radio waves from the beacon 310, the user's smartphone terminal 320 accesses the server 330 and displays a predetermined attendance menu screen 321 on the display unit.
When the user operates the attendance menu screen 321 , the user's smartphone terminal 320 transmits attendance information based on the operation on the attendance menu screen 321 to the server 330 .
The server 330 is then configured to record the attendance information received from the user's smartphone terminal 320 in a database 331 together with the user name information and date and time information.

As a result, the attendance menu screen 321 is displayed based on reception of radio waves from the beacon 310, and the user simply operates the attendance clock-in/clock-out buttons, and attendance information, user name information, and date and time information are recorded in the database 331.
As a result, convenience for users is improved and the manager can easily manage the attendance records of each user using the manager's computer terminal 340 .
For example, there is no need to wait in line for a time card punching machine, nor is there need to wait in line for an IC card type card reader device; instead, the user can simply operate buttons to clock in, clock out, go out, return, etc. in a designated area AR near the entrance/exit of the building BD, thereby improving user convenience.

Next, the operation of the attendance management system 300 will be described in more detail.
As shown in FIG. 10, in step S21, as a reception determination step, it is determined whether or not the user's smartphone terminal 320 is receiving radio waves from a beacon 310 installed in a predetermined area AR at an entrance/exit of a predetermined indoor space.
If it is determined that the signal has been received, the process proceeds to step S22. On the other hand, if it is determined that the signal has not been received, step S21 is repeated.

In step S22, as shown in FIG. 11, as an attendance menu display step, the user's smartphone terminal 320 accesses the server 330 based on preset URL information and displays a predetermined attendance menu screen 321 on the display unit.
The attendance menu screen 321 is provided with, as an example, a "Clock in" button, a "Leave work" button, a "Go out" button, a "Return to work" button, a "Break time" button, and a comment input field.
In step S23, as an operation determination step, the user's smartphone terminal 320 determines whether or not the user has performed an operation on the attendance menu screen 321.
If it is determined that an operation has been performed, the process proceeds to step S24. On the other hand, if it is determined that no operation has been performed yet, step S23 is repeated.

In step S24, as a transmission step, the user's smartphone terminal 320 transmits attendance information based on operations on the attendance menu screen 321 to the server 330.
For example, when the user taps the “Come to work” button on the attendance menu screen 321, the smartphone terminal 320 transmits attendance information indicating “Come to work” to the server 330.
In step S25, as a recording step, the server 330 records the attendance information received from the user's smartphone terminal 320 in the database 331 together with the user name information and date and time information.

For example, when attendance information indicating “arrived at work” is received, the user name information is identified from identifiable information such as the registration information and MAC address (Media Access Control address) information of the sending user's smartphone terminal 320, and is recorded in the database 331 together with date and time information.
As a result, as described above, the attendance menu screen 321 is displayed based on reception of radio waves from the beacon 310, and the user simply presses the attendance clock-in/clock-out buttons, and attendance information, user name information, and date and time information are recorded in the database 331.
As a result, convenience for users is improved and the manager can easily manage the attendance records of each user using the manager's computer terminal 340 .
