[0023] (An example of a power supply management system) FIG. 1 is a schematic diagram of an example of the power supply management system of the present disclosure used in an example of a working space.

[0024] Note that the illustrated working space 6 has a plurality of seats (not shown) where telephones 51, 52,... 5 n (n is a natural number of 2 or more) are installed, and further includes an attendance management terminal 8. The illustrated attendance management terminal 8 is installed in the internal area of the working space 6 near its entrance / exit 7, but it can also be installed in the external area of the working space 6 or at a location away from the entrance / exit 7.

[0025] The power supply management system 1 includes an in-building switch 2, a seat management server 3, and a power supply hub 4. The in-building switch 2 and the seat management server 3 are connected to a network (intranet, Internet, etc.). Note that in this example, the seat management server 3 can be either on-premises type or cloud type, the working space 6 can be either a company office or a shared office, and the seats can be either fixed seats or flexible seats.

[0026] Connected to the in-building switch 2 is a power supply hub 4 having a plurality of power supply ports for respectively supplying power to the seat management server 3 that manages a plurality of seats installed in the working space 6 and the telephones 51, 52,... 5 n installed on each seat in the working space 6. Therefore, each telephone 51, 52,... 5 nIt is connected to the in-building switch 2 via a power supply hub 4 with a LAN (Local Area Network) cable.

[0027] (An example of an in-building switch) FIG. 2 is a block diagram of an example of the in-building switch 2 of the present disclosure.

[0028] The in-building switch 2 includes a receiving unit 2a, a specifying unit 2b, a transmitting unit 2c, and a control unit 2d.

[0029] The receiving unit 2a is configured to receive an identification number assigned to a specific telephone (a telephone to be powered on installed at a seat reserved by a user). In this example, the in-building switch 2 or the receiving unit 2a receives the identification number of the specific telephone from the seat management server 3.

[0030] The specifying unit 2b is configured to receive the identification number received by the receiving unit 2a from the receiving unit 2a and specify the port number of the power supply hub 4 corresponding to this identification number. This specification can be performed, for example, by collating the identification number acquired from the receiving unit 2a with the telephone information (FIG. 3) stored in the storage unit (not shown) of the in-building switch 2. The storage unit stores telephone information of each telephone 51, 52,... 5 n of the telephones, for example, the MAC (Media Access Control) addresses, port numbers, and identification numbers of each telephone 51, 52,... 5 n are stored in the form of a telephone information table as shown in FIG. 3, for example. Also, as shown in FIG. 3, the storage unit can store internal line numbers and the like.

[0031] The transmitting unit 2c is configured to receive the port number specified by the specifying unit 2b from the specifying unit 2b and transmit a power supply command (i.e., power on of the specific telephone) at the power supply port corresponding to this port number to the power supply hub 4.

[0032] The control unit 2d is configured to control the operations of the receiving unit 2a, the specifying unit 2b, the transmitting unit 2c, and the storage unit.

[0033] (Example of seat management server) FIG. 4 is a block diagram of an example of the seat management server of the present disclosure.

[0034] The seat management server 3 includes a storage unit 3a, a determination unit 3b, a transmission unit 3c, and a control unit 3d.

[0035] (Storage unit) The storage unit 3a stores identification numbers assigned to the telephones 51, 52,... 5 installed on each of the plurality of seats. Note that the storage unit 3a can further store the positions of the plurality of seats (seat positions) in the working space 6, especially in association with the identification numbers of the telephones 51, 52,... 5 installed respectively. n n

[0036] (Determination unit) The determination unit 3b is configured to determine whether or not a seat has been reserved by a user.

[0037] Regarding the determination of whether or not a seat has been reserved by a user, the determination unit 3b can determine that there is a seat reservation by the user, for example, in the following cases (1) to (3) (however, it is not limited to these cases).

[0038] (1) When the user logs in to the seat management server 3 connected to the information terminal installed on the seat at the information terminal installed on the seat.

[0039] (2) When the determination unit 3b or the seat management server 3 obtains the identification number assigned to the telephones 51, 52,... 5 installed on the seat from the user communication terminal. n

[0040] Telephones 51, 52,... 5 n ​​​The identification number assigned to [[ID=]] can be recorded, for example, in an identifier (such as a QR (Quick Response) code (registered trademark), barcode, etc.) attached to the telephone set or the seat where the telephone set is installed. In this case, the user uses the imaging function (such as a camera) of the user communication terminal to image the identifier, and transmits the identification number (information including the identification number) recorded in the identifier to the determination unit 3b or the seat management server 3.

[0041] Also, for telephones 51, 52,... 5 n The identification number assigned to [[ID=]] can be recorded, for example, in an IC (Integrated Circuit) chip built into an NFC (Near Field Communication) tag provided on the telephone set or the seat where the telephone set is installed. In this case, the user uses the short-range wireless communication function of the user communication terminal to read the identification number (information including the identification number) recorded in the IC chip, and transmits this to the determination unit 3b or the seat management server 3.

[0042] Also, for telephones 51, 52,... 5 n The identification number assigned to [[ID=]] can also be displayed on the telephone set or the seat where the telephone set is installed. In this case, the user notifies the seat management server 3 or the determination unit 3b of the identification number by transmitting it to a reception email address using the user communication terminal.

[0043] (3) When a user registers the use of a seat from a specific date and time on an information terminal connected to the seat management server 3.

[0044] This can be done, for example, by a user who is already logged in using an application having a seat reservation function (hereinafter also referred to as a "seat reservation application") on an information terminal installed on the seat to register (reserve) the use of the seat from a specific date and time after the next day (including a specific time after that day).

[0045] In addition, for example, the commuting management terminal 8 shown in FIG. 1 can function as an information terminal directly or indirectly connected to the seat management server 3. In this case, if a seat reservation application (or a part thereof) can be executed on the commuting management terminal 8, the user can also perform the above registration (reservation) on the commuting management terminal 8 when exiting the working space 6 (for example, leaving work). Further, the user can also perform the above registration (reservation) on the commuting management terminal 8 when entering the working space 6 (for example, arriving at work). In this case, the determination unit 3b can also determine that there is a seat reservation by the user simultaneously with the registration (reservation).

[0046] In addition, the user communication terminal can usually also function as an information terminal. In this case, if a seat reservation application (or a part thereof) can be executed on the user communication terminal, the user can perform the above registration (reservation) regardless of time and place.

[0047] In addition, the above specific date and time are set by the user, but may also be a specific time determined in advance such as the start time.

[0048] In addition, the seats in each of the above examples may be either fixed seats or free seats. However, especially in the case of fixed seats, it is also possible to register in advance the arrival time of each user in the seat management server 3 and determine that there is a seat reservation by the user at that time.

[0049] (Transmission unit) When the determination unit 3b determines that there is a seat reservation by the user, the transmission unit 3c is configured to transmit the identification number assigned to the specific telephone to the in-house switch 2.

[0050] In the case of the determination example (3) of the presence or absence of a seat reservation by the user, the transmission unit 3c is configured to transmit to the in-house switch 2 the identification number of the specific telephone at the above specific date and time, or to transmit a command indicating that power supply to the specific telephone should be awaited until the above specific date and time, together with the identification number.

[0051] The control unit 3d is configured to control the operations of the storage unit 3a, the determination unit 3b, and the transmission unit 3c.

[0052] (Operation example) FIG. 5 shows a timing chart of an example of the operation of the power supply management system of this example. It is assumed that the power of the telephone on an unreserved seat is OFF.

[0053] First, the user makes a seat reservation to the seat management server 3 (S1). Note that "S" means step.

[0054] Next, the seat management server 3 identifies the telephone installed on the reserved seat (S2), and transmits the identification number of the identified telephone to the in-house switch 2 (S3).

[0055] Next, the in-house switch 2 identifies the port number of the power supply hub 4 corresponding to the received identification number (S4), and commands the power supply hub 4 to turn on the power supply port of the identified port number (S5). In response to this, the power of the specific telephone is turned on (S6).

[0056] In this way, the present disclosure can turn on only the power of the telephone for the user who works in the working space of the employee who has come to the office, etc., by interlocking the in-house switch and the seat management system, and can avoid the consumption of unnecessary standby power.

[0057] (Another example of the power supply management system) FIG. 6 is a schematic diagram of another example of the power supply management system of the present disclosure used in an example of a working space, and FIG. 7 is a block diagram of an example of the in-house switch constituting the power supply management system shown in FIG. 6.

[0058] Among the components of the working space and the power supply management system shown in FIG. 6, the description of those common to the components of the working space and the power supply management system shown in FIG. 1 is omitted. Also in this example, the working space 6 may be a company office or a shared office, and the seats may be fixed seats or free seats.

[0059] The power supply management system 1' includes an in-building switch 2' and a power supply hub 4 connected to the in-building switch 2'.

[0060] The in-building switch 2' is configured to include an incoming call receiving unit 2e instead of (or in addition to) the receiving unit 2a in the in-building switch 2 shown in FIG. 2. Note that the in-building switch 2' may be configured such that the receiving unit 2a in the in-building switch 2 also has the function of the incoming call receiving unit 2e.

[0061] The incoming call receiving unit 2e is configured to receive an incoming call with an identification number assigned to a specific telephone added from a user communication terminal connected to the in-building switch 2'.

[0062] In this case, the identification number of the specific telephone is visibly displayed on the telephone or its seat, etc., and the user uses this identification number with the user communication terminal to make a call to the in-building switch 2' in the form of, for example, "reception telephone number + delimiter number (#, etc.) + identification number", and the incoming call receiving unit 2e receives the incoming call with this identification number added.

[0063] Also, the identification number of the specific telephone is recorded in an IC chip built into an identifier or an NFC tag, and the user communication terminal can read the identification number of the specific telephone from these and, in particular, automatically add this identification number and make a call to the in-building switch 2'.

[0064] The configuration and operation of the specific unit 2b, transmission unit 2c, and control unit 2d of the in-building switch 2' are the same as the configuration and operation of the specific unit 2b, transmission unit 2c, and control unit 2d of the in-building switch 2 shown in FIG. 2.

[0065] (Operation example) FIG. 8 shows a timing chart of an example of the operation of the power supply management system of this example. It is assumed that the power of the telephones at unreserved seats is OFF.

[0066] First, the user uses the user communication terminal to make a call to the in-building switch 2' with the reserved seat or the identification number of the telephone attached to the telephone (S10).

[0067] Next, the in-building switch 2' identifies the port number of the power supply hub 4 corresponding to the received identification number (S20), and commands the power supply hub 4 to turn on the power supply port of the identified port number (S30). In response, the power of the specific telephone is turned on (S40).

[0068] In this way, the present disclosure can turn on only the power of the telephone for the user who works in the working space of the employees who come to the office, etc., and can avoid the consumption of unnecessary standby power.

[0069] Furthermore, in this example, since the in-building switch 2' directly receives the identification number of the specific telephone, the seat management server 3 becomes unnecessary. However, the power supply management system 1' can additionally include the above seat management server 3, and this configuration is not excluded from the present disclosure.

[0070] (Development example) In each of the above examples, the power supplies of the telephones 51, 52,... 5 n can also be turned off at a predetermined time (for example, closing time).

[0071] Furthermore, the power supplies of the telephones 51, 52,... 5 n can also be turned off, for example, when the user logs off on the information terminal installed at the seat when leaving work, or when the user registers leaving work with the seat management server 3 via the attendance management terminal 8. In this case, for example, the determination unit 3b determines that the reservation for the seat has ended when there is a logoff operation or a registration of leaving work, etc., and the transmission unit 3c transmits the identification numbers of the telephones 51, 52,... 5 n at that seat to the in-building switches 2, 2', and the in-building switches 2, 2' command the power supply hub 4 to turn off the power supply port corresponding to the identification number.

[0072] Furthermore, in this example, for example, in order to enable an operation of setting (extension number / originating number / phone directory / originating and terminating call history / function buttons, etc.) for the telephones 51, 52, … 5 n corresponding to the user who has reserved a seat, the identification numbers of the telephones 51, 52, … 5 n are used. However, if such an operation is not necessary, an extension number may be used instead of the identification number.

[0073] The above control unit (or control circuit) can be configured using so-called hardware resources (information processing devices, computers), and those having the configuration exemplified in FIG. 9 can be used. For example, the hardware resource 1000 can include a processor 1001, a memory 1002, a network interface 1003, etc., which are mutually connected by an internal bus 1004.

[0074] However, the configuration shown in FIG. 9 is not intended to limit the hardware configuration of the hardware resource 1000. The hardware resource 1000 may include hardware not shown (for example, an input / output interface). For the processor 1001, for example, a CPU (Central Processing Unit), an MPU (Micro Processor Unit), a GPU (Graphics Processing Unit), etc. can be used.

[0075] Also, for the memory 1002, for example, a RAM (Random Access Memory), a ROM (Read Only Memory), an HDD (Hard Disk Drive), an SSD (Solid State Drive), etc. can be used. Here, a predetermined threshold value regarding the above predetermined physical quantity can be stored in the memory 1002, and a control program for performing the above control can also be stored.

[0076] Furthermore, for the network interface 1003, for example, a LAN (Local Area Network) card, a network adapter, a network interface card, etc. can be used.

[0077] Furthermore, the functions of the hardware resources 1000 are realized by a processing module. The processing module is realized, for example, by the processor 1001 executing a program stored in the memory 1002. Also, the program can be downloaded via a network or updated using a storage medium storing the program. Furthermore, the above processing module may be realized by a semiconductor chip. That is, the functions performed by the above processing module may be realized as long as software is executed in some hardware.
