In this embodiment, the "predetermined area" or "facility" is, for example, an office building, factory, hotel, art museum, museum, commercial complex, amusement facility, theme park, residence, etc. including buildings. In addition, the "predetermined area" or "facility" may be a moving body such as a railway vehicle or a ship. The positioning system using the human position detection system 10 in this embodiment is used in places where it is difficult to receive radio waves from artificial satellites used in global positioning systems such as GPS (Global Positioning System), such as buildings and moving objects. When a target such as an interior, an underground facility, or a tunnel is a predetermined area A1 (facility), it is used to measure the position of the transmitter 40 within the predetermined area A1 (facility). In particular, in this embodiment, the predetermined area A1 (facility) will be described as a certain site and a group of offices built on that site.

The human position detection system 10 of this embodiment includes a transmitter 40, a plurality of receivers 20, a position information acquisition section 331, a determination section 333, and a notification section 334, as shown in FIG. Note that the number of receivers 20 is not limited to a plurality of receivers, and may be one.

The transmitter 40 is carried by each person H who is permitted to enter the predetermined area A1 (facility) (see FIG. 3), and transmits individual information by radio wave. The transmitter 40 in this embodiment is, for example, a radio wave transmitter dedicated to a positioning system, such as a tag, but may also be a communication module of an information terminal 70, which will be described later. Further, the person H who is permitted to enter the predetermined area A1 (facility) is a worker of the predetermined area A1 (facility). One transmitter 40 is carried by each person H to enter (see FIG. 2), and each transmitter 40 transmits individual information by radio wave. The individual information is, for example, identification information such as an ID (IDentification) individually assigned to each person H to be admitted.

The plurality of receivers 20 are installed in a predetermined area A1 (facility) and receive individual information transmitted by radio waves from the transmitter 40. Upon receiving the individual information, the receiver 20 transmits information including the individual information to the server 30 via the network 200.

Since the individual information is transmitted, it can be said that the position information acquisition unit 331 acquires the individual position information regarding the current position of each person H to enter.

The determination unit 333 in the server 30 determines the person H to be admitted from among the plurality of people H to be admitted. A specific area A2 (see FIG. 3) is set inside the predetermined area A1 (facility). In particular, in this embodiment, the "specific area" will be explained as one building of the aforementioned office group. When a plurality of persons H to enter exist within a specific area A2, if the exit from the specific area A2 progresses and there are only a few persons H to enter, these few persons H to enter remain. can be said to be a candidate for the final exiter of the specific area A2. Since the location information acquisition unit 331 has acquired individual location information for each person H to enter, the determination unit 333 determines that the person H to enter whose individual location information is within the specific area A2 exists in the specific area A2. can be determined. In this way, the determination unit 333 checks the number of people H to enter the specific area A2, and if the number of people H to enter the specific area A2 becomes equal to or less than a predetermined threshold, the determination unit 333 confirms the number of people H to enter the specific area A2. The entry target person H existing in A2 is determined to be a candidate for notification as a candidate for the final exit person. Note that the above-mentioned description of "several people remaining" corresponds to the description of "number of people below a predetermined threshold," but the "predetermined threshold" is not limited to "several people" and may be set to various numbers. .

Based on the result determined by the determination unit 333, the notification unit 334 notifies the admission target person H determined to be the notification target that he or she is a candidate for the final exit person. This "notification" is sent to the information terminal 70 (see FIG. 2) carried by each person H to enter. The information terminal 70 is a terminal such as a smartphone or a mobile phone, but also includes information devices such as a tablet-type mobile terminal or a notebook computer.

The transmitter 40 is possessed and carried by each person H to be admitted, and the individual information emitted by the transmitter 40 has a one-to-one correspondence with each person H to be admitted, so the individual location information is information indicating the current location of each person H to be admitted. becomes. In this embodiment, the current position of the transmitter 40 corresponds to the position at the time when the receiver 20 receives the wireless signal from the transmitter 40. In this embodiment, since wireless transmission from the transmitter 40 is performed at intervals of 0.1 seconds, the individual position information is also acquired and updated at intervals of 0.1 seconds and stored in the storage unit 32.

The relationship between the entrance/exit authentication terminal 60, the ID card 61, and the server 30 will be explained. An entrance/exit authentication terminal 60 is provided at the entrance/exit to the predetermined area A1 (facility). The entrance/exit authentication terminal 60 is, for example, a non-contact card reader terminal. The entrance/exit authentication terminal 60 communicates with the server 30 via the network 200 within a predetermined area A1 (facility). The communication method of the entrance/exit authentication terminal 60 is, for example, a communication method based on the Ethernet (registered trademark) standard, but the communication method of the entrance/exit authentication terminal 60 can be selected from various communication methods, and even a wired communication method can be used. A wireless communication method based on a standard such as WiFi (registered trademark) may be used. Further, the entrance/exit authentication terminal 60 may be connected to the network 200 via a relay device such as a router or a hub.

The ID card 61 is, for example, a contactless IC (Integrated Circuit) card, and is carried by each person H to be admitted. A non-volatile memory or the like in the ID card 61 stores different information for each person H to enter.

Each time the person H to enter enters or exits the predetermined area A1 (facility), he brings the ID card 61 close to the entrance/exit authentication terminal 60. In this embodiment, there are two types of entrance/exit authentication terminals 60: an entrance/exit authentication terminal 60 (entrance side) that authenticates entry, and an entrance/exit authentication terminal 60 (exit side) that authenticates exit. exist.

When a person H to enter enters a predetermined area A1 (facility), when the ID card 61 is brought close to the entrance/exit authentication terminal 60 (entrance side), the information in the ID card 61 is detected by the entrance/exit authentication terminal 60 (entrance side). The information is read and the information in ID card 61 is sent to server 30 via network 200. When the information in the ID card 61 is sent to the server 30, the entrance/exit information recording unit 332 in the CPU 33 determines that the person H to enter has entered, and records the entry from the exit state as the entrance/exit information for the person H to enter. The state is changed and stored in the storage unit 32. There is a one-to-one correspondence between the person H to enter and the ID card 61, and information for specifying the person H to enter is stored for each ID card 61. Therefore, the entrance/exit information recording unit 332 uses the information in the ID card 61. The person H to enter who brought the ID card 61 close to the entrance/exit authentication terminal 60 (entrance side) is identified, and is stored in the storage unit 32 as entrance/exit information as being in the entrance state. That is, bringing the ID card 61 close to the entrance/exit authentication terminal 60 (entrance side) has the function of turning on the entrance/exit information to the entrance state. Note that when the entrance/exit information recording unit 332 stores the entrance/exit information of the person H to enter in the storage unit 32 as being in the admission state, the storage unit 32 may also store the time at which the admission state was changed at the same time. good.

When the person to be admitted H leaves the predetermined area A1 (facility), he or she brings the ID card 61 close to the entrance/exit authentication terminal 60 (exit side). At this time, the information in the ID card 61 is read by the entrance/exit authentication terminal 60 (exit side) in the same way as when entering, and the information in the ID card 61 is transmitted to the server 30 via the network 200. When the information in the ID card 61 is sent to the server 30, the entrance/exit information recording unit 332 determines that the person H to enter has left the venue, and changes the entry/exit information of the person H to enter from the admission state to the exit state. and stores it in the storage unit 32. Identifying the person H to enter based on the information in the ID card 61 is the same at the time of exit as at the time of entry. In this way, bringing the ID card 61 close to the entrance/exit authentication terminal 60 (exit side) has the function of turning off the entrance state and turning it into the exit state as entrance/exit information. Note that when the entrance/exit information recording unit 332 stores the entrance/exit information of the person H to enter in the storage unit 32 as being in the exiting state, the storage unit 32 may also store the time at which the entry state was changed to the exiting state at the same time. good.

Due to the relationship between the entrance/exit authentication terminal 60, the ID card 61, and the server 30 as described above, the entrance/exit information indicating whether the person H to enter is entering or leaving the predetermined area A1 (facility) is the entry target. The information is stored in the storage unit 32 for each person H.

Although the relationship and configuration of the entrance/exit authentication terminal 60, ID card 61, and server 30 for acquiring entrance/exit information for each person H to enter has been explained, the above explanation is an example and is not limited to this. . As another configuration, the card reader of the entrance/exit authentication terminal 60 may be configured such that the same card reader is used both at the time of entrance and at the time of exit, without separating the card reader for the entrance side and the exit side. A server 30 including an entrance/exit information recording section 332 and a storage section 32 that stores entrance/exit information, and a server 30 that includes a location information acquisition section 331 and a storage section 32 that stores individual location information are separated as separate servers. The configuration may be such that the servers 30 communicate with each other. Further, the entrance/exit authentication terminal 60 may be any type of biometric authentication device instead of a non-contact card reader. If the entry/exit authentication terminal 60 is a biometric authentication device, the ID card 61 may be changed to the fingerprint, iris, face shape, etc. of the person H to enter, depending on the type of biometric authentication device.

The relationship between the device control system 50, the device 51, and the server 30 will be explained. In this embodiment, the device 51 will be described as a lighting device. The equipment 51 is installed in the grounds (outdoors) and all buildings and rooms 100 within a predetermined area A1 (facility). FIG. 2 shows an example in which a plurality of devices 51 are installed in a room 100.

The device control system 50 is a device that changes the power supply state to the device 51 in order to control the device 51 to turn on, turn off, or dim. The device control system 50 is installed, for example, in each building in a predetermined area A1 (facility), and controls the devices 51 installed in the building. Furthermore, a device control system 50 that controls devices 51 installed outdoors may be separately provided. There are various methods for connecting the device control system 50 and the device 51. For example, in this embodiment, the device control system 50 is connected to a device control terminal (not shown) via a communication line, and Or a plurality of devices 51 are connected. The equipment control terminal includes a communication device and a power supply circuit, and according to commands communicated from the equipment control system 50 to the equipment control terminal, the equipment control terminal controls the electricity supply state of the equipment 51 connected to the equipment 51. Turn on, turn off, or dim. If power is supplied to the device 51, the device 51 lights up, if the power to the device 51 is cut off, the device 51 turns off, and if the current of the device 51 changes, the illuminance of the device 51 changes. By dividing the device control terminal and the devices 51 connected to the device control terminal into groups to be controlled in advance in a building, the device 51 can be controlled for each room or for each predetermined area. The device 51 can be turned on and off using a switch installed in the room, but the device 51 can be further controlled to turn on and off by commands from the device control system 50.

The device control system 50 is connected to the server 30 via the network 200. The device control unit 335 transmits a command to control the device 51 to the device control system 50, and the device control system 50 controls the device 51 according to the contents of the command. The command sent by the equipment control unit 335 to the equipment control system 50 is, for example, a command to turn on or off all the equipment 51 installed in the building, or a command to turn on or turn off only the equipment 51 in a certain room. Although the command may be to turn off the light, the command may be changed as appropriate. Note that in this embodiment, the device 51 has been described as a lighting device, but the device 51 is not limited to a lighting device, and the device 51 may be an electrical device having various communication functions, such as an air conditioner or a display. . Further, communication between the device control system 50 and the device 51 is not limited to communication via the device control system 50, and may be communication not via the device control system 50. A command to control the device 51 may be issued directly from the device control system 50 to the device 51 without going through the device control system 50.

The schedule recording unit 336 is one of the functional units of the CPU 33 of the server 30. The schedule recording unit 336 causes the storage unit 32 to store the schedule for each person H to enter, in response to the input signal of the schedule for the day for each person H to enter. Input of the schedule by the person to be admitted H is performed from the schedule application on the information terminal 70 or laptop computer owned by each person H to be admitted. The schedule application is managed by an individual account for each person H to be admitted, and the person H to be admitted enters schedule information of the person H to be admitted, such as the schedule contents, time zone, and place where the plan is to be held for a certain day. It is desirable that the place where the appointment is to be made is entered by distinguishing whether it is within the predetermined area A1 (facility) or not.

The schedule of the person to be admitted H entered in the schedule application by the person to be admitted H is transmitted to the server 30 via the network 200 from a terminal such as an information terminal 70 running the application or a notebook computer. When the information regarding the schedule is transmitted to the server 30, the schedule recording unit 336 stores the schedule of the person to be admitted H in the storage unit 32. The schedule of the person to be admitted H stored in the storage unit 32 can also be confirmed by another person to be admitted through the schedule application. Information regarding the schedule of person H to enter may be processed and used in various ways. For example, the schedule after a certain time may be extracted from the schedule for the day and used in the form of "remaining schedule." Note that in this embodiment, the location information acquisition section 331 and the schedule recording section 336 exist in the CPU 33 of the same server 30, and the individual location information and schedule are also stored in the storage section 32 of the same server 30. Not limited to. For example, one server 30 has a location information acquisition unit 331 and a storage unit 32 that stores individual location information, another server 30 has a schedule recording unit 336 and a storage unit 32 that stores schedules, and two The servers 30 may communicate with each other via the network 200.

The determination unit 333 is one of the functional units of the CPU 33 of the server 30. The determining unit 333 determines how many people H are present in a predetermined area A1 (facility) based on the individual position information and entry/exit information for each person H stored in the storage unit 32. judge. Furthermore, if the number of persons H to enter within the specific area A2 becomes equal to or less than a predetermined threshold, the determination unit 333 determines that the persons H to be admitted are to be notified. The human position detection system 10 performs various operations including notification according to the determination content of the determination unit 333. The specific content of the determination performed by the determination unit 333 and the operation of the human position detection system 10 after the determination will be described in detail in each embodiment described later.

The notification unit 334 is one of the functional units of the CPU 33 of the server 30. Based on the determination made by the determining unit 333, a notification is sent to the information terminal 70 carried and carried by the person H to enter that the person H is the final exit candidate. The notification signal from the notification unit 334 to the information terminal 70 is transmitted via the communication unit 31 of the server 30. As described above, the information terminal 70 is a terminal such as a smartphone or a mobile phone. The information terminal 70 corresponds one-on-one to each person H to be admitted, and the correspondence information is stored in advance in the storage unit 32, so the notification unit 334 notifies the information terminal 70 possessed by a specific person H to be admitted. It is possible to issue a notification signal only.

When the information terminal 70 receives the notification signal issued from the notification unit 334, the information terminal 70 displays a message on the display of the information terminal 70 indicating that the person H to enter who is in possession of the information terminal 70 is the final exit candidate for the specific area A2. Display a pop-up message notifying you of this. When the information terminal 70 receives a notification signal from the notification unit 334, the information terminal 70 may sound a ringtone.

(3-1) First Example A first example of the operation of the human position detection system 10 of this embodiment will be described using FIGS. 3 to 4. FIG. 3 shows an example of the state of the predetermined area A1 (facility). In this embodiment, in a predetermined area A1 (facility), a first building exists as a specific area A2, and a second building exists as an area A3. The persons H1 to H12 to be admitted are the persons H to be entered who are individually assigned numbers, and are shown to be scattered inside and outside the predetermined area A1 (facility). In particular, this indicates that it is the moment for the person to enter H4 to exit the specific area A2 (first building). The person H to enter enters and leaves the predetermined area A1 (facility) through the entrance/exit 80.

As shown in FIG. 2, a plurality of receivers 20 are installed on the ceiling 101 in the specific area A2 (first building) and area A3 (second building). Therefore, within the specific area A2 (first building) and area A3 (second building), individual location information is transmitted at 0.1 second intervals by wireless transmission from the transmitter 40 carried by the person H to enter. be obtained.

The specific operation of the first embodiment will be described below, focusing on the specific area A2 (first building). First, the position information acquisition unit 331 of the human position detection system 10 acquires individual position information of the transmitter 40 (S11). At this time, since the persons H1 to H8 to enter are in the first building or the second building, their individual position information is acquired and stored in the storage unit 32, but the persons H9 to H12 to enter are in the first building or the second building. Since the person is not in any of the buildings, no individual position information is acquired, and information indicating “no individual position information” is stored in the storage unit 32.

When the individual location information is acquired in S11, the determination unit 333 reads the individual location information from the storage unit 32 and determines the number of persons H to enter in the specific area A2 (first building) (S12). The determination unit 333 determines whether or not the person H to enter is within the specific area A2 (first building) because position information defining the specific area A2 (first building) is set in advance. This can be determined by comparing the location information that defines A2 (first building) with the individual location information. Through this comparison, the determining unit 333 identifies the persons H to enter within the specific area A2 (first building) and determines the number of them.

When the number of people H to enter the specific area A2 (first building) is determined, the determination unit 333 determines that the number of people H to enter the specific area A2 (first building) is less than or equal to a predetermined threshold. (S13). In this embodiment, the threshold value is temporarily set to 3. In FIG. 3, the number of persons H to enter in the first building is 4 until just before the person H4 to enter leaves the first building (No in S13), so the acquisition process of individual position information in S11 is performed again. conduct. In FIG. 3, when the person H4 to enter leaves the first building, the number of persons H to enter in the first building becomes 3, so the determination unit 333 determines that the number of persons H to enter in the first building is 3. It is determined that the value has become equal to or less than the threshold value (Yes in S13).

When the determining unit 333 determines that the number of persons H to enter within the specific area A2 (first building) has become equal to or less than a predetermined threshold, the determining unit 333 selects the persons H to be admitted who are in the first building as notification targets ( (S14). In FIG. 3, immediately after the person to be admitted H4 leaves the first building, the persons to be admitted H1 to H3 in the first building are determined to be the notification targets.

When the determination unit 333 determines the person H to be notified, the notification unit 334 sends a notification to the person H to be notified, who is the final exit candidate for the first building, based on this determination. Execute (S15). In FIG. 3, the notification targets are the admission candidates H1 to H3, so the notification unit 334 sends a notification to the information terminals 70 carried by the admission candidates H1 to H3, who are the final exit candidate candidates.

With the above-described flow, the person position detection system 10 sends a notification to the person H who remains in the first building to enter, that he or she is the final candidate to leave the first building. By receiving a notification on the information terminal 70, the person H to enter can recognize that he/she has become the final candidate to leave the first building, so he/she can turn off the lights of the equipment 51 in the first building or take other actions. This has the advantage of preventing you from forgetting to turn off the power to electrical equipment. In addition, since the individual location information of the person H to enter is automatically grasped by the person position detection system 10, even if the first building is an office with a free address system where specific seats are not determined, the first building This has the advantage of being able to ascertain the number of people in the room and notify the final exit candidates. In the present embodiment, the threshold value for the number of people to be determined as notification targets is set to 3, but the threshold value may be changed as appropriate according to the actual state of operation of the specific area A2 (first building).

(3-2) Second Example A second example of the operation of the human position detection system 10 of this embodiment will be described using FIGS. 5 and 6. FIG. 5 shows an example of the state of the predetermined area A1 (facility). There is a specific area A2 (first building) and area A3 (second building) in a predetermined area A1 (facility), and the receiver 20 is installed on the ceiling 101 of the first building and the second building. Since this is the same as the first embodiment, the explanation will be omitted. However, this embodiment differs from the first embodiment in that an entrance/exit authentication terminal 60 is provided beside the entrance/exit 80 to the predetermined area A1 (facility).

In FIG. 5, numbers H1 to H12 are assigned to persons H to enter inside and outside a predetermined area A1 (facility), and this indicates the moment when person H4 to enter exits from the first building. This is similar to the first embodiment, but differs from the first embodiment in that the "area to which the person H to enter" is further written in < >. In the second embodiment, a "belonging area" is assigned to each person H to be admitted, and is stored in the storage unit 32 as "belonging area information". The notation H1<A2> for admission target person indicates that a specific area A2 (first building) is assigned as the area to which the person belongs. Further, in FIG. 5, the icon of the person H to enter who belongs to the specific area A2 (first building) is shaded.

As for the movement of the person H to enter due to the area to which each person H belongs is allocated, for example, when person H1<A2> goes to work in the predetermined area A1 (facility), the person H1 <A2> moves in the area to which he/she belongs. He enters a certain No. 1 building and mainly performs his duties there. After that, depending on work circumstances, you may move to various locations within the predetermined area (facility) A1, such as area A3 (second building), but ultimately return to the first building, exit from the predetermined area (facility) A1, and leave work. do. That is, the area to which the person belongs is an area set as a base of activities for each person H to enter within the predetermined area (facility) A1. Hereinafter, expressions such as "the belonging area is the first building", "the belonging area information is the first building", and "belonging to the first building" will be used.

The specific operation of the second embodiment will be described below, focusing on a specific area A2 (first building). First, the entrance/exit information recording unit 332 of the person position detection system 10 acquires and records the entrance/exit information of the person H to enter (S21). The entrance/exit information is acquired by bringing the ID card 61 close to the entrance/exit authentication terminal 60 when the person H to enter enters or exits the predetermined area A1 (facility), and is stored in the storage unit 32. In FIG. 5, the entry/exit information for persons H1 to H10 and H13 indicates the entry state, and the entry/exit information for the persons H11 to H12 indicates the exit state.

When the entrance/exit information is acquired in S21, the position information acquisition unit 331 acquires the individual position information of the transmitter 40 (S22). At this time, since the persons H1 to H8 and H13 to enter are in the first building and the second building, their individual position information is acquired and stored in the storage unit 32, but the persons H9 to H12 to enter are in the first building and the second building. Since the user is not in the second building, no individual position information is acquired, and information indicating "no individual position information" is stored in the storage unit 32.

When the individual location information is acquired in S22, the determination unit 333 reads the belonging area information and the individual location information from the storage unit 32, and determines whether the individual location information is within the specific area A2 (first building) and the specific area A2 (first building). The number of persons H to enter the building (S23) is determined. In S23, the number of persons H to enter is determined by, for example, identifying the persons H to enter who are in the first building as in the first embodiment, and further determining whether or not the belonging area information is the first building. This is done by narrowing down.

When the number of persons H to enter who belong to the specific area A2 (first building) within the specific area A2 (first building) is determined, the determining unit 333 It is determined whether the number of persons H to enter who belong to the specific area A2 (first building) is equal to or less than a predetermined threshold (S24). In this embodiment, the threshold value is temporarily set to 3. In FIG. 5, until just before the person H4 to enter the first building leaves the first building, the number of people H4 in the first building to be judged in S24 is 4 (No in S24), so the process is repeated in S21. Obtain entry/exit information. In FIG. 5, when the person H4 to enter leaves the first building, the number of people H4 to enter who belong to the first building in the first building becomes three, so the determination unit 333 It is determined that the number of persons H to enter the building belonging to the building has become equal to or less than a predetermined threshold (Yes in S24).

When the determining unit 333 determines that the number of persons H to enter who belong to the specific area A2 (first building) within the specific area A2 (first building) has become equal to or less than a predetermined threshold, the determining unit 333 determines whether or not to enter the specific area A2 (first building). The entry target person H whose exit information is an entry state and whose area belongs to the specific area A2 (first building) is determined to be a notification target (notification transmission target) (S25). In FIG. 5, immediately after the person to be admitted H4 leaves the first building, the persons to be admitted H1, H2, H4, H8, H9, and H13 are determined to be the notification targets. The entry target person H11 belongs to the specific area A2 (first building), but since the entry/exit information indicates an exit state, the entry target person H11 is not determined to be a notification target.

When the determination unit 333 determines the person H to be notified, the notification unit 334 sends a notification to the person H to be notified, who is the final exit candidate for the first building, based on this determination. Execute (S26). In the second embodiment, the notification unit 334 sends notifications to the information terminals 70 carried by the admission candidates H1, H2, H4, H8, H9, and H13, who are final exit candidate candidates.

In addition, in FIG. 5, the case where the person to be admitted H leaving the first building is not the person to be admitted H4 but the person to be admitted H3 will be described. In S24, even if the person to be entered H3 leaves the specific area A2 (first building), the area to which the person to be entered H3 belongs is area A3 (second building). The number of persons H to enter who belong to the specific area A2 (first building) within the building remains unchanged at 4. Therefore, since the number of admission candidates H to be determined in S24 does not become less than the threshold value (No in S24), the notification unit 334 does not issue a notification.

In the above-described flow, the person position detection system 10 sends a notification to the person H who is the subject of notification that he or she is the final exit candidate for the first building. Compared to the first embodiment, even if the determination of the number of persons H remaining in the specific area A2 (first building) is the same, the notification target is in the admission state, and the specific area A2 ( The difference is that the person to be admitted is H who belongs to the first building). In FIG. 5, the persons H4, H8, and H9 who are subject to admission have left the first building, but remain within the predetermined area A1 (facility) and may return to the first building. In this way, by sending a notification that the person H to enter who may return to the area to which he/she belongs is also a final exit candidate, it is possible for such person H to enter to turn off the lights of the equipment 51 in the first building. This has the advantage of preventing you from forgetting to turn off the power to other electrical devices. In addition, in determining the number of persons H remaining in the specific area A2 (first building), the number of persons H remaining in the specific area A2 (first building) is changed to the number of persons H belonging to the specific area A2 (first building). We have narrowed it down to only person H. Since the person to be admitted H3 does not belong to the first building, if such person to be admitted H3 is included as a target for counting to determine whether the number of people remaining in the first building is greater than or equal to the threshold value. , there is a risk that the notification of the final exit candidate may not be properly given to the person H who belongs to the first building and is subject to admission. For example, in FIG. 5, if the area to which the persons H1 to H4 belong is area A3 (second building), the first building has only persons H who belong to the second building, and the first building has only persons H who belong to the second building. A notification of the final exit candidate for the building is sent to the entry target H who is in the entry state and belongs to the first building. The second embodiment has the advantage of eliminating the possibility that such notification of the final exit candidate will not be made appropriately. Note that the threshold value in S24 may be changed as appropriate, similar to the first embodiment.

(3-3) Third Example A third example of the operation of the human position detection system 10 of this embodiment will be described using FIGS. 7 and 8. FIG. 7 shows an example of the state of the predetermined area A1 (facility). There is a specific area A2 (first building) and area A3 (second building) in a predetermined area A1 (facility), and the receiver 20 is installed on the ceiling 101 of the first building and the second building. Since this is the same as the first embodiment, the explanation will be omitted.

In FIG. 7, numbers H1 to H6 are assigned to persons H to enter inside and outside a predetermined area A1 (facility), and the moment H1 to enter indicates the moment of exit from the first building. .

The specific operation of the third embodiment will be described below, focusing on a specific area A2 (first building). First, the position information acquisition unit 331 of the human position detection system 10 acquires individual position information of the transmitter 40 (S31). At this time, since the persons H1 to H2 to enter are in the first building and the second building, their individual position information is acquired and stored in the storage unit 32, but the persons H3 to H6 to enter are in the first building and the second building. Since the person is not inside the building, no individual position information is acquired, and information indicating "no individual position information" is stored in the storage unit 32.

When the individual position information is acquired in S31, the determining unit 333 reads the individual position information from the storage unit 32 and determines the number of persons H to enter in the specific area A2 (first building) (S32). The method for determining the number of persons H to enter within the specific area A2 (first building) is the same as that in the first embodiment, so the explanation will be omitted.

When the number of people H to enter the specific area A2 (first building) is determined, the determination unit 333 determines whether the number of people H to enter the specific area A2 (first building) is zero. (S33). In FIG. 9, the number of persons H to enter in the first building is 1 until just before the person H1 to enter leaves the first building (No in S33), so the acquisition of individual position information in S31 is performed again. . In FIG. 7, when the person H1 to enter leaves the first building, the number of people H1 to enter in the first building becomes zero, so the determination unit 333 determines that the number of people H1 to enter in the first building becomes zero. (Yes in S33).

When the determination unit 333 determines that the number of persons H to enter in the specific area A2 (first building) has become zero, the device control unit 335 turns off the device 51 in the specific area A2 (first building) ( S34). The device control unit 335 transmits a command to the device control system 50 that controls the devices 51 in the first building via the network 200, and cuts off the power to the devices 51 in the first building to turn off the lights. This light-off control may be a control that turns off all the devices 51 in the first building, or may be changed as appropriate according to the actual state of operation of the first building, such as not turning off some of the devices 51.

With the above-described flow, the human position detection system 10 turns off the lights of the equipment 51 in the first building where the person H to enter is no longer present. Since the individual position information of the person H to enter the first building is automatically grasped by the person position detection system 10, the first building is a free-address system in which specific seats are not determined. Even in an office, the number of people in the first building can be ascertained, and when there are no more persons H to enter the first building, the equipment 51 in the first building can be automatically turned off, thereby preventing forgetting to turn it off. It has the advantage of being able to

(3-4) Fourth Example A fourth example of the operation of the human position detection system 10 of this embodiment will be described using FIGS. 9 to 10. FIG. 9 shows an example of the state of the predetermined area A1 (facility). There is a specific area A2 (first building) and area A3 (second building) in a predetermined area A1 (facility), and the receiver 20 is installed on the ceiling 101 of the first building and the second building. Since this is the same as the first to third embodiments, the explanation will be omitted. Also, similar to the second embodiment, an entrance/exit authentication terminal 60 is provided beside the entrance/exit 80 to the predetermined area A1 (facility).

9 is similar to FIG. 7 in that numbers are assigned to the persons H1 to H6 to enter, and that the moment when the person H1 exits from the first building is shown. On the other hand, in FIG. 9, in addition to the state shown in FIG. 7, the "area to which the person belongs" is allocated to the person H to enter, and the person H to enter further indicates the "area to which he belongs" in < >. There is. “Belonging area information” indicating the area to which the person to be admitted H belongs is also stored in the storage unit 32. Further, as in the second embodiment, the icon of the person H to enter who belongs to the specific area A2 (first building) is shown in shading.

The specific operation of the fourth embodiment will be described below, focusing on a specific area A2 (first building). First, the entrance/exit information recording unit of the person position detection system 10 acquires and records the entrance/exit information of the person H to enter (S41). The entrance/exit information is acquired by bringing the ID card 61 close to the entrance/exit authentication terminal 60 when the person H to enter enters or exits the predetermined area A1 (facility), and is stored in the storage unit 32. In FIG. 9, the entry/exit information for persons H1 to H4 indicates an entry state, and the entry/exit information for persons H5 to H6 indicates an exit state.

When the entrance/exit information is acquired in S41, the location information acquisition unit 331 acquires the individual location information of the transmitter 40 (S42). At this time, since the persons H1 to H2 to enter are in the first building and the second building, their individual position information is acquired and stored in the storage unit 32, but the persons H3 to H6 to enter are in the first building and the second building. Since the person is not inside the building, no individual position information is acquired, and information indicating "no individual position information" is stored in the storage unit 32.

When the individual location information is acquired in S42, the determination unit 333 reads the individual location information from the storage unit 32 and determines the number of persons H to enter in the specific area A2 (first building) (S43). The method for determining the number of persons H to enter within the specific area A2 (first building) is the same as that in the first embodiment, so the explanation will be omitted.

When the number of people H to enter the specific area A2 (first building) is determined, the determination unit 333 determines whether the number of people H to enter the specific area A2 (first building) is zero. (S44). In FIG. 9, the number of persons H to enter in the first building is 1 until just before the person H1 to enter leaves the first building (No in S44), so the acquisition of the entrance/exit information in S41 is performed again. . In FIG. 9, when the person H1 to enter leaves the first building, the number of persons H to enter in the first building becomes zero, so the determination unit 333 determines that the number of persons H to enter in the first building is zero. It is determined that there is one (Yes in S44).

When the determining unit 333 determines that the number of persons H to enter in the specific area A2 (first building) is zero, the determining unit 333 further determines that the entrance/exit information is in the admission state and that the number of persons H to enter in the specific area A2 (first building) is zero. It is determined whether there is one or more persons H to enter who belong to one building (S45). The determination in S45 can be made, for example, by reading the entry/exit information and the belonging area information from the storage unit 32 and determining whether both match the determination content in S45. In FIG. 9, immediately after the person H1 to enter leaves the first building, the number of people H1 to enter who are in the admission state and belong to the specific area A2 (first building) is 2, that is, 1 or more. Therefore, the process returns to S41 to obtain entrance/exit information (Yes in S45). If Yes in S45, the device control unit 335 maintains the power of the device 51 and maintains the lighting state of the device 51.

After it is determined as Yes in S45, the process goes from S41 to S45 again, and if the person to be admitted H1 and the person to be admitted H3 have exited from the entrance/exit 80 from FIG. It is determined that there is no person H to enter who belongs to area A2 (first building) (No in S45).

The determination unit 333 determines that the number of persons H to enter in the specific area A2 (first building) is zero, and there are no persons H to enter who belong to the specific area A2 (first building) in the admission state. If so, the device control unit 335 turns off the device 51 in the specific area A2 (first building) (S46). In S46, the equipment control unit 335 transmits a command to the equipment control system 50 that controls the equipment 51 in the first building via the network 200, cuts off the power to the equipment 51 in the first building, and turns off the equipment 51. This control to turn off the lights may be a control that turns off all the equipment 51 in the first building, or may be controlled as appropriate depending on the actual state of operation of the first building, such as maintaining the power of some equipment 51 and not turning off the lights. May be changed.

According to the above-described flow, the human position detection system 10 is configured such that even if the person H to enter the first building disappears, the person H to enter the predetermined area A1 (facility) remains in the predetermined area A1 (facility), and the person H who belongs to the first building is still in the predetermined area A1 (facility). If it exists, control is performed to maintain power to the equipment 51 in the first building and keep the equipment 51 lit. In FIG. 9, when the person H1 to enter leaves the first building, the person H1 to enter is absent from the first building, but the person H1 or H3 to enter ends their schedule in the predetermined area A1 (facility). , there is a possibility that it will return to the first building. At this time, if the equipment 51 of the first building is turned off when the number of persons H to enter in the first building reaches zero as in the third embodiment, When person H returns to the first building, the first building is dark and there is a possibility of inconvenience. In the fourth embodiment, even if the number of persons H to be admitted in the first building becomes zero, the number of persons H to be admitted in the first building is kept until all the persons H to be admitted belonging to the first building have left the predetermined area A1 (facility). By controlling the lighting of the equipment 51 in one building, it is possible to automatically turn off the equipment 51 in the first building while eliminating the above-mentioned inconvenience, and there is an advantage that it is possible to prevent forgetting to turn off the equipment 51 in the first building.

(3-5) Fifth Example A fifth example of the operation of the human position detection system 10 of this embodiment will be described using FIGS. 11A to 12. FIG. 11A and FIG. 11B show an example of the state of the predetermined area A1 (facility). There is a specific area A2 (first building) and area A3 (second building) in a predetermined area A1 (facility), and the receiver 20 is installed on the ceiling 101 of the first building and the second building. Since this is the same as the first to fourth embodiments, the explanation will be omitted. Also, similar to the second and fourth embodiments, an entrance/exit authentication terminal 60 is provided beside the entrance/exit 80 to the predetermined area A1 (facility).

In FIGS. 11A and 11B, numbers are assigned to persons H1 to H6, and the moment when person H1 exits the first building is shown. ” is allocated, and the “area to which the person H belongs” is further written in < >, as in FIG. 9 . “Belonging area information” indicating the area to which the person to be admitted H belongs is also stored in the storage unit 32 in the same way. On the other hand, in addition to the state shown in FIG. 9, in FIGS. 11A and 11B, schedule information indicating whether or not the admission target person H in the admission state has a schedule remaining for the day is also described. Further, as in the second and fourth embodiments, the icon of the person H to enter who belongs to the specific area A2 (first building) is shown in shading. Note that the difference between FIG. 11A and FIG. 11B is whether or not there is a remaining schedule for the admission target person H3, and while there is no remaining schedule in FIG. 11A, there is a remaining schedule in FIG. 11B.

The specific operation of the fifth embodiment will be described below, focusing on a specific area A2 (first building). First, the entrance/exit information recording unit 332 of the person position detection system 10 acquires and records the entrance/exit information of the person H to enter (S51). The entrance/exit information is acquired by bringing the ID card 61 close to the entrance/exit authentication terminal 60 when the person H to enter enters or exits the predetermined area A1 (facility), and is stored in the storage unit 32. In FIGS. 11A and 11B, the entry/exit information for the persons H1 to H4 indicates the entry state, and the entry/exit information for the persons H5 to H6 indicates the exit state.

When the entrance/exit information is acquired in S51, the schedule recording unit 336 acquires information regarding the schedule for each person H to enter, and stores it in the storage unit 32 (S52). Information regarding the schedule of the person to be admitted H is inputted by the schedule application of the information terminal 70 or other electronic device owned by each person to be admitted, and the result is transmitted to the server 30 via the network 200. The schedule recording unit 336 stores the schedule in the storage unit 32 .

When the schedule of the person to be admitted H is acquired in S52, the location information acquisition unit 331 acquires the individual location information of the transmitter 40 (S53). At this time, since the persons H1 to H2 to enter are in the first building and the second building, their individual position information is acquired and stored in the storage unit 32, but the persons H3 to H6 to enter are in the first building and the second building. Since the person is not inside the building, no individual position information is acquired, and information indicating "no individual position information" is stored in the storage unit 32.

When the individual position information is acquired in S53, the determination unit 333 reads the individual position information from the storage unit 32 and determines the number of persons H to enter in the specific area A2 (first building) (S54). The method for determining the number of persons H to enter within the specific area A2 (first building) is the same as that in the first embodiment, so the explanation will be omitted.

When the number of people H to enter the specific area A2 (first building) is determined, the determination unit 333 determines whether the number of people H to enter the specific area A2 (first building) is zero. (S55). In FIGS. 11A and 11B, until just before the person H1 to enter the first building leaves the first building, the number of persons H1 to enter the first building is 1 (No in S55), so the entry/exit information in S51 is again Perform the acquisition. In FIG. 11A, when the person H1 to enter leaves the first building, the number of persons H to enter in the first building becomes zero, so the determination unit 333 determines that the number of persons H to enter in the first building is zero. It is determined that there is one (Yes in S55).

When the determination unit 333 determines that the number of persons H to enter in the specific area A2 (first building) is zero, the determination unit 333 further determines that the entrance/exit information is the admission state and that the number of persons H to enter the specific area A2 (first building) is zero. It is determined whether there is one or more persons H to enter who belong to the first building (S56). The determination at S56 can be made, for example, by reading entry/exit information and belonging area information from the storage unit 32 and determining whether both pieces of information match the determination content at S56. If the entrance/exit information is in the entry state and there is not one or more persons H to enter who belong to the specific area A2 (first building) (No in S56), the device control unit 335 The equipment 51 in A2 (first building) is turned off (S58).

In S56, if the entry/exit information is in the entry state as shown in FIGS. 11A and 11B, and there is one or more persons H to enter who belong to the specific area A2 (first building) (in S56 Yes), proceed to S57.

When the determination unit 333 determines that “the entry/exit information is in the admission state and there is one or more persons H to enter who belong to the specific area A2 (first building),” the determination unit 333 further determines that It is determined whether there is one or more persons H whose entry/exit information is in the entry state, who belong to the specific area A2 (first building), and who have a schedule remaining (S57). The determination in S57 can be made, for example, by reading in information regarding the schedule from the storage unit 32 in addition to the entry/exit information and the belonging area information, and checking whether all the conditions match the determination content in S57. . In FIGS. 11A and 11B, an example in which the schedule after a certain time of the day's schedule of person H to enter is processed into information called "remaining schedule" and written next to the icon indicating person H to be admitted in the admission state. It shows. Hereinafter, the present embodiment will be described assuming that the determination in S57 is made at 18:50.

In FIG. 11A, the persons H1 and H3 are in the entry state and belong to the specific area A2 (first building), but the persons H1 and H3 are both 18: At the time of 50, there is no remaining schedule. That is, since there is no one or more persons H to enter whose entry/exit information is in the entry state, who belong to the specific area A2 (first building), and who have a schedule remaining (No in S57), the process moves to S58. Then, the device control unit 335 turns off the device 51 in the specific area A2 (first building) (S58).

In FIG. 11B, the persons H1 and H3 are in the entry state and belong to the specific area A2 (first building). As of 18:50, the person H1 to enter has no remaining schedule, but the person H3 to enter has a remaining schedule in area A3 (second building) from 19:00 to 20:00. That is, since there is one or more persons H to enter whose entry/exit information is in the entry state, who belong to the specific area A2 (first building), and who have a schedule remaining (Yes in S57), the process moves to S59. do.

In S57, when the determination unit 333 determines that "there is one or more persons H to enter whose entry/exit information is in the entry state, who belong to the specific area A2 (first building), and who have a schedule remaining". , the device control unit 335 maintains the power of the device 51 in the specific area A2 (first building) until a predetermined time has elapsed from the end of the schedule to maintain the lighting state of the device 51, and then turns off the power of the device 51. is shut off and the device 51 is turned off (S59). In this example, if the predetermined time is 10 minutes, at the time of S57 and S58, the remaining schedule is the schedule of person H3 to enter from 19:00 to 20:00 in the second building. The unit 335 keeps the equipment 51 in the first building lit until 20:10, and then turns off the light.

In the above example, in S57 and S59, "Entrance target person H whose entry/exit information is in the admission state, who belongs to specific area A2 (first building), and has a schedule remaining" is determined to be an entry target. Since the remaining schedule is from 19:00 to 20:00, equipment 51 in the first building was kept lit until 20:10. If there are more than one, the lighting of the equipment 51 in the first building is maintained until the time obtained by adding 10 minutes of the predetermined time to the latest time of the plurality of remaining schedules. Furthermore, since S51 to S59 are repeatedly carried out at regular intervals, if the person H to enter returns to the first building while the equipment 51 in the first building remains lit, no Then, the determination and operation from S51 are performed again while the lighting of the equipment 51 in the first building is maintained. Note that the method and operation of turning off the lights of the equipment 51 in the first building in S58 and S59 may be changed as appropriate according to the actual situation of the first building, as in the third and fourth embodiments. Further, the predetermined time for maintaining the lighting of the device 51 is not limited to 10 minutes, and may be changed as appropriate.

According to the above-described flow, the human position detection system 10 is configured such that even if the person H to enter the first building disappears, the person H to enter the predetermined area A1 (facility) remains in the predetermined area A1 (facility), and the person H who belongs to the first building is still in the predetermined area A1 (facility). If there is a remaining schedule for the person H to enter, control is performed to maintain the lighting of the equipment 51 in the first building until a predetermined time has elapsed from the end of the schedule. In FIG. 11B, when the person H1 to enter leaves the first building, the person H3 to enter is absent from the first building, but since the person H3 to enter has a remaining schedule, the person H3 to enter is scheduled in area A3 (second building). There is a possibility that you will return to the first building after finishing. At this time, if the equipment 51 of the first building is turned off when the number of persons H to enter in the first building reaches zero as in the third embodiment, When person H returns to the first building, the first building is dark and there is a possibility of inconvenience. In the fifth embodiment, even if the number of persons H to enter in the first building becomes zero, the persons H to enter who are in the predetermined area A1 (facility) and belong to the first building remain. If there is a schedule, by performing control to keep the equipment 51 in the first building turned on until a predetermined time has elapsed after the end of the remaining schedule, the equipment 51 in the first building can be switched on while eliminating the above-mentioned inconvenience. 51 can be automatically turned off, and there is an advantage that forgetting to turn it off can be prevented.

As mentioned above, the embodiments of the present invention have been described with reference to the drawings (FIGS. 1 to 12). However, the scope of the invention is not limited by the above. Various modifications and changes can be made to the present invention within the scope of the gist of the present invention as set forth in the claims.
