The above-mentioned clock-in system using geofences is used in various industries, but some industries have a wide work area and multiple workers work in multiple time zones and multiple areas (for example, firefighting activities by fire department personnel, search activities for missing persons, manufacturing and construction work at factories and construction sites, event management, etc.). It may not be desirable in terms of work efficiency for workers in such industries to go to a specific time-in area determined in advance just to clock in, etc. In particular, when the work is something that requires urgent action, such as firefighting or searching for missing persons, it may be urgent to go to a work area outside the time-in area. In addition, depending on the work content, the start time of the work may differ from the start time of other work. Therefore, it may not be desirable in terms of work efficiency to only be able to clock in within a specific time-in area. However, in the conventional technology, the specific time-in area is determined by a program. If this area needs to be changed, the administrator must change it manually. Such a change work is time-consuming and difficult to handle when it is required to go to a work area outside the time-in area in a hurry.

A server according to one aspect of the present invention includes a communication unit that communicates with each of a plurality of preregistered portable terminal devices, a setting unit that sets a recordable area, and a recording unit that, when it detects through communication by the communication unit that the terminal device has entered the recordable area, records entry information including the time that the terminal device entered the recordable area and information identifying the terminal device that has entered the recordable area, and the setting unit updates the recordable area when a predetermined update condition is met after the recordable area has been set.

Each aspect of the present invention may be realized by a computer. In this case, the present invention also includes a program that causes the computer to operate as each unit (software element) of the system to realize the system, and a computer-readable recording medium on which the program is recorded.

First Embodiment
First, a server 1 according to a first embodiment of one aspect of the present invention will be described.

[composition]
As shown in FIG. 1 , the server 1 includes a communication unit 11 , a storage unit 12 , and a control unit 13 .

[Communications Department]
The communication unit 11 communicates with each of a plurality of preregistered portable terminal devices 2. The communication unit 11 according to the present embodiment is configured with a wireless communication module. That is, the communication unit 11 according to the present embodiment wirelessly communicates with the terminal devices 2.

[Memory unit]
The storage unit 12 according to the present embodiment is configured with a semiconductor memory, a hard disk drive, etc. The storage unit 12 according to the present embodiment also stores an update rule table and a database 121.

As shown in Figure 2, the update rule sheet shows information about the initial (default) recordable range, as well as the correspondence between the update conditions and the recordable area after the update. Details of the update conditions and the recordable area will be explained later.

Database 121 is capable of storing multiple incident management forms (for each incident). As shown in FIG. 3, the incident management form indicates the incident number, the location of the incident, the people scheduled to attend the incident, the scheduled date and time of the incident, the type of incident, and the number of people who have already attended. The location of the incident includes the center of the work area, the entrance and exit of the work area, the planned location of specific equipment (fire engines, etc.), the planned waiting location of the person in charge of the work, etc. The location of the incident may be indicated by an address or by latitude and longitude.

[Control Unit]
The control unit 13 controls each unit of the server 1. The control unit 13 according to the present embodiment includes a setting unit 131, a transmission control unit 132, a reception control unit 133, and a recording unit 134.

(Settings section)
The setting unit 131 sets the recordable area _R1 . The setting unit 131 according to the present embodiment sets the recordable area _R1 according to the location of the case described in the case management form. The recordable area _R1 set by the setting unit 131 according to the present embodiment is a circle with a predetermined radius centered on a predetermined point. The predetermined point according to the present embodiment is the "location of the case" described in the case management form. The recordable area _R1 may extend horizontally or vertically. The recordable area _R1 may be a space such as a sphere or a cylinder including the predetermined point. The setting unit 131 updates the recordable area _R1 when a predetermined update condition is met after the recordable area _R1 is set. Details of the update of the recordable area _R1 will be described later.

(Transmission control section)
The transmission control unit 132 controls the communication unit 11 to transmit the area information to a plurality of terminal devices 2. The area information is information indicating the range of the recordable area _R1 set by the setting unit 131. The transmission control unit 132 according to the present embodiment controls the transmission of the area information to at least the terminal devices 2 possessed (including the case where the terminal device 2 is worn) by the prospective participants of the cases listed in the case management form. The transmission control unit 132 may be configured to control the transmission of the area information to all registered terminal devices 2. When the setting unit 131 updates the recordable area _R1 , the transmission control unit 132 according to the present embodiment controls the communication unit 11 to transmit the area information of the updated recordable area _R1 to a plurality of terminal devices 2.

(Reception control section)
The reception control unit 133 controls the communication unit 11 to receive entry information from the terminal device 2. The entry information is information indicating that the terminal device 2 has entered the recordable area _R1 . In this way, the communication unit 11 receives the entry information every time each terminal device 2 enters the recordable area _R1 .

(Recording section)
The recording unit 134 records the attendance information when it detects through communication by the communication unit 11 that the terminal device 2 has entered the recordable area _R1 . The attendance information is information including the time when the terminal device ₂ entered the recordable area R1 and information identifying the terminal device 2 that has entered the recordable area _R1 . The recording unit 134 according to this embodiment records the attendance information when the communication unit 11 receives the entry information. Furthermore, the recording unit 134 according to this embodiment records the attendance information in the database 121 of the storage unit 12. Furthermore, the recording unit 134 according to this embodiment updates (+1) the information on the number of people who have entered, which is written on the case management form, every time it records the attendance information.

(Setting section after recordable area is set)
As described above, the setting unit 131 updates the recordable area _R1 when an update condition is met after the recordable area _R1 is set. The setting unit 131 according to this embodiment updates the location information of the case written in the case management form according to the update rule sheet stored in the memory unit 12. As described above, the setting unit 131 sets the recordable area _R1 according to the location of the case written in the case management form. Therefore, when the location of the case is updated, the recordable area _R1 is also updated.

The "update" of the recordable area _R1 includes at least one of "radius expansion,""new area setting," and "area change." Note that the "update" may also include "reduction."

When "radius expansion" is to be updated, the setting unit 131 expands the recordable area _R1 by increasing the radius of the recordable area _R1 , as illustrated in Fig. 4. This allows the setting unit 131 to easily control the setting and expansion of the recordable area _R1 .

When the "new area setting" is set as an update, the setting unit 131 updates the recordable area _R1 by setting a new recordable area R _a separately from the initially set recordable area R1, as illustrated in FIG. _5. The new recordable area R _a may be connected to the initially set recordable area _R1 or may be separated from it (FIG. 5 illustrates a case where the new recordable area R a is connected). This allows the recordable area _R1 to be expanded in a form that corresponds to the topography, the layout of buildings and roads, the movement tendency of the multiple terminal devices 2, and the like, unlike the case where the recordable area R1 is simply expanded. When the setting unit 131 according to this embodiment detects that the terminal device ₂ has entered the recordable area _R1 , it sets a new recordable area R _a including the position of the terminal device 2. This increases the new recordable area R _a on the side of the initial recordable area R1 where the worker entered. Therefore, when multiple workers are all coming toward the recordable area _R1 from the same direction, the new recordable area R _a will extend toward the direction in which the workers are flowing, or will move toward the direction in which the workers are flowing. This allows multiple workers to clock in and out with less movement.

When "area change" is regarded as an update, the setting unit 131 updates the recordable area R1 by changing the recordable area _R1 from the initially set recordable area _R1 to a new recordable area _R2 as shown in Fig. _6. The position of the new recordable area _R2 may be a position including the position indicated by the position information when the position indicated by the position information falls within the recordable area _R1 , as in the case of the above-mentioned "new area setting", or may be a position determined in advance.

The "update conditions" include at least one of the "number of people conditions" and the "time conditions".

When the number of people condition is set as the update condition, the setting unit 131 updates the recordable area _R1 when the number of attendance information recorded by the recording unit 134 reaches a predetermined number (for example, 1). As a result, when a predetermined number of workers have finished clocking in when they come to work, the recordable area _R1 is expanded or changed. Therefore, workers who come to work later can clock in when they come to work (record attendance information) without going to the original recordable area _R1 . In addition, when the number of people condition is set as the update condition, the setting unit 131 further updates the recordable area _R1 each time the number of people condition is met and the second, third, ... nth number of people condition is met (the number of attendance information recorded by the recording unit 134 reaches the second, third, ... nth predetermined number that is greater than the predetermined number: see FIG. ₂ ).

When the time condition is set as the update condition, the setting unit 131 updates the recordable area _R1 when a predetermined time has passed since the recording unit 134 recorded the first entry information. As a result, the recordable area _R1 is expanded when a predetermined time has passed since the first worker to arrive at work has finished punching in. Therefore, workers who arrive later can punch in when they arrive at work without going to the original recordable area _R1 . Furthermore, when the time condition is set as the update condition, the setting unit 131 further updates the recordable area _R1 each time the second, third, ... nth time condition is satisfied (the second, third, ... nth time that is longer than the predetermined time has passed since the recording unit 134 recorded the first entry information) after the time condition is satisfied and the setting unit 131 updates the recordable area _R1 .

[Action and Effect]
According to the server 1 described above, the recordable area _R1 is automatically updated (enlarged or changed) (without placing a burden on the manager) when a predetermined update condition is met (a predetermined number of entries reaches, a predetermined time has passed since the first entry information is recorded). As a result, after the update condition is met, most workers who have the terminal device 2 can clock in (record entry information) without having to go to the original recordable area _R1 .

<Terminal Device>
Next, the terminal device 2 that communicates with the server 1 will be described.

[composition]
The terminal device 2 is portable. The terminal device 2 may be a dedicated device, or may be a mobile phone, tablet terminal, or the like carried by each worker. As shown in FIG. 7 , the terminal device 2 according to the present embodiment includes a terminal communication unit 21, a terminal storage unit 22, and a terminal control unit 23.

[Terminal communication unit]
The terminal communication unit 21 communicates with the server 1. The terminal communication unit 21 according to the present embodiment is configured with a wireless communication module. That is, the terminal communication unit 21 according to the present embodiment wirelessly communicates with the server 1. The terminal communication unit 21 according to the present embodiment also communicates with satellites of a Global Navigation Satellite System (GNSS).

[Memory unit]
The terminal storage unit 22 stores a dedicated application program. The terminal storage unit 22 according to the present embodiment is configured to store area information. The terminal storage unit 22 according to the present embodiment is configured with a semiconductor memory, a hard disk drive, etc. The terminal storage unit 22 may be divided into one that stores the application program and one that stores the area information.

[Terminal control unit]
The terminal control unit 23 controls each unit of the terminal device 2. The terminal control unit 23 according to this embodiment is configured with a processor. The terminal control unit 23 executes various processes according to application programs stored in the terminal storage unit 22. The terminal control unit 23 according to this embodiment includes a terminal reception control unit 231, a position information generation unit 232, a terminal determination unit 233, and a terminal transmission control unit 234.

(Reception control section)
The terminal reception control unit 231 controls the terminal communication unit 21 to receive area information from the server 1. The terminal reception control unit 231 according to this embodiment controls reception of area information periodically or every time the server 1 updates the recordable area _R1 . The terminal reception control unit 231 according to this embodiment stores the area information received by the terminal communication unit 21 in the terminal storage unit 22.

(Location information generating unit)
The position information generating unit 232 generates position information indicating the position of the terminal device 2 (itself). The position information generating unit 232 according to this embodiment generates position information based on a signal received by the terminal communication unit 21 from a GPS satellite. The position information according to this embodiment is information indicating the latitude and longitude of the terminal device 2. The position information may include information indicating the height of the terminal device 2. In this way, it is possible to deal with cases where the recordable area _R1 extends vertically or is a space. In addition, the position information generating unit 232 periodically generates position information. As described above, the terminal device 2 is portable and may move. For this reason, the content of the position information may change each time it is generated.

(Terminal Determination Unit)
The terminal determination unit 233 determines whether the terminal device 2 has entered the recordable area _R1 . Specifically, the terminal determination unit 233 determines whether the position indicated by the most recent position information generated by the position information generation unit 232 is within the range of the recordable area _R1 indicated by the area information received by the terminal communication unit 21. The terminal determination unit 233 according to this embodiment periodically determines whether the terminal device 2 has entered the recordable area _R1 each time the terminal communication unit 21 receives area information or each time the position information generation unit 232 generates position information.

(Terminal transmission control section)
The terminal transmission control unit 234 controls the terminal communication unit 21 to transmit entry information to the server 1 when the terminal determination unit 233 determines that the terminal device 2 has entered the recordable area R ₁ .

[motion]
When the terminal device 2 described above enters the recordable area _R1 , it notifies the server 1 to that effect.

Second Embodiment
Next, a second embodiment of the present invention will be described. For the sake of convenience, the same reference numerals will be used to designate components having the same functions as those described in the first embodiment, and the description thereof will not be repeated.

[Differences in configuration]
As shown in FIG. 8, the server 1A according to this embodiment includes a control unit 13A in addition to the communication unit 11 and storage unit 12 similar to those of the server 1 according to the first embodiment.

The control unit 13A includes a setting unit 131 similar to the control unit 13 according to the first embodiment, as well as a reception control unit 133A, a recording unit 134A, and a judgment unit 135.

(Reception control section)
The reception control unit 133A controls the communication unit 11 to repeatedly receive location information indicating the location of each of the multiple terminal devices 2 from the multiple terminal devices 2 .

(Judgment Department)
The determination unit 135 determines whether the terminal device 2 has entered the recordable area _R1 . The determination unit 135 according to this embodiment determines whether the position indicated by the most recent position information received by the reception control unit 133A is within the range of the recordable area _R1 indicated by the area information set by the setting unit 131. The determination unit 135 according to this embodiment determines whether the terminal device 2 has entered the recordable area _R1 periodically, every time the setting unit 131 sets or updates the recordable area _R1 , or every time the communication unit 11 receives position information.

(Recording section)
The recording unit 134A according to the present embodiment records the entry information when the position indicated by the position information enters the recordable area R _1. Moreover, the recording unit 134A according to the present embodiment records the entry information in the database 121 of the storage unit 12, similar to the recording unit 134 according to the first embodiment.

[Action and Effect]
According to the server 1A described above, similarly to the server 1 according to the first embodiment, the recordable area _R1 is automatically updated when a predetermined update condition is met. As a result, after the update condition is met, most workers who have the terminal device 2 can clock in and out without having to go to the original recordable area _R1 .

<Modifications of the first and second embodiments>
The control unit 13, 13A may include an acquisition unit 136 as shown in FIG. 9. The acquisition unit 136 acquires the number of visitors who have entered the predetermined area among a plurality of people other than the holder of the terminal device 2. In this case, the setting unit 131 may be configured to update the recordable area R ₁ when the number of visitors acquired by the acquisition unit 136 reaches a predetermined number. The number of visitors may be received, for example, from a counting device (such as an entrance gate) provided in the predetermined area, or may be calculated based on location information received from a mobile phone carried by the visitor. For example, if the predetermined area is an event venue and the holder of the terminal device 2 is an event staff member, the more the number of event participants who are visitors increases, the more the staff members will be dispersed to various places in the venue to work. For this reason, by doing as described above, a worker who arrives at work later can stamp his/her arrival time without going to the original recordable area R _1. As a result, the worker can start work at his/her post earlier than if he/she went to the recordable area R ₁ .

The communication unit 11 may be configured to communicate with a device different from the terminal device 2. The device includes, for example, a device used by a worker for work (for example, a fire engine used for firefighting work, etc.). In this case, the setting unit 131 may be configured to set a new recordable area R _a including the location of the device, or to change the location to a new recordable area R ₂ , when detecting that the device has entered the predetermined area. The "predetermined area" may be the recordable area R ₁ , or may be another area (such as an actual work location). Workers often gather near the device used for work. For this reason, by doing as described above, after the device arrives in the predetermined area, many workers can stamp their attendance without going to the original recordable area R ₁ .

Furthermore, the setting unit 131 may be configured to set a new recordable area R _a including the position of the specific terminal device 2, or change it to a new recordable area R ₂ , when detecting that a specific terminal device 2 among the multiple terminal devices 2 has entered the specified area. The "specified area" may be the recordable area R ₁ , or may be another area. Workers often gather near the person in charge who is the main body of the work. For this reason, by having the person in charge carry the specific terminal device 2 as described above, after the specific terminal device 2 arrives in the specified area, many workers can clock in and out without going to the original recordable area R ₁ .

In addition, when setting the recordable area _R1 , the setting unit 131 may be configured to set the second recordable area _R3 at a position different from the recordable area _R1 (setting a plurality of recordable areas _R1 at once) as shown in FIG. 10. In this case, the recording unit 134 may be configured to record the entry information when it detects that the terminal device 2 has entered the recordable area _R1 or the second recordable area _R3 . In this case, the setting unit 131 may be configured to update at least one of the recordable area _R1 and the second recordable area _R3 when an update condition is satisfied after the recordable area _R1 is set (FIG. 10 illustrates a case where only the recordable area _R1 is updated). In this way, even if the work place is divided into two or more places, after the update condition is satisfied, many workers who have the terminal device 2 can punch in at the time of coming to work without going to the original recordable area _R1 .

Furthermore, the setting unit 131 may be configured to update the recordable area _R1 based on an area change instruction received from a specific terminal device 2 (manually by the holder of the specific terminal device 2) among the multiple terminal devices 2. In this way, by having the specific terminal device 2 held by a responsible person, the recordable area _R1 can be changed flexibly according to the judgment of the responsible person.

The functions of the server 1 can be realized by a program for making a computer function as the server 1 and for making a computer function as each control block of the server 1 (particularly each part included in the control unit 13). In this case, the server 1 includes a computer having at least one control device (e.g., a processor) and at least one storage device (e.g., a memory) as hardware for executing the program. The functions described in the above embodiment are realized by executing the program using the control device and the storage device. The program may be recorded on one or more computer-readable recording media, not on a temporary basis. The recording media may or may not be included in the device. In the latter case, the program may be supplied to the device via any wired or wireless transmission medium.

In addition, some or all of the functions of each of the above control blocks can be realized by a logic circuit. For example, an integrated circuit in which a logic circuit that functions as each of the above control blocks is formed is also included in the scope of the present invention. In addition, it is also possible to realize the functions of each of the above control blocks by, for example, a quantum computer.

The effects of each aspect of the present invention described above will contribute to the achievement of Goal 9 of the Sustainable Development Goals (SDGs) advocated by the United Nations, "Build resilient infrastructure, promote inclusive and sustainable industrialization, and innovate inclusive and sustainable ways."

Furthermore, the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. The technical scope of the present invention also includes embodiments obtained by appropriately combining the technical means disclosed in different embodiments.
