In addition, the basic function unit (201 in FIG. 10) uses the computer power control unit (203 in FIG. 10) to send a magic packet for performing the “resume” state transition operation to the corresponding computer device (employee code ( (User code) is transmitted to the computer device corresponding to C1 (B14). The computer power control receiving unit (302 in FIG. 113) of the computer device receives the magic packet transmitted in step B14, and “resumes” the computer device using the computer power control unit (303 in FIG. 13). The state transition operation is performed. As a result, the power state of the computer device temporarily shifts to the operating state (B15).

  Subsequently, the basic function unit (201 in FIG. 10) uses the computer power control unit (203 in FIG. 10) to send a magic packet for performing a state transition operation of “power off” to the corresponding computer device (employee). The code (user code) C1 is transmitted to the computer device (B16). The computer power control receiving unit (302 in FIG. 13) of the computer apparatus receives the magic packet transmitted in step B16, and uses the computer power control unit (303 in FIG. 13) to send “power off” to the computer apparatus. State transition operation is performed. As a result, the power state of the computer device shifts to the power off state (B17).

  Next, the power supply control device 4 updates the status in the computer device database (6 in FIG. 11) to the power-off state (B18). The above is the operation related to power control performed on the computer device (18a to 18f in FIG. 4) when the employee (user) leaves or leaves the room.

  In FIG. 15, after step B8 (that is, after the employee (user) leaves the room), the lighting device / air conditioner power supply control (B19) is performed in parallel. Details of the power supply control (B19) of the lighting device / air conditioner will be described later with reference to FIG.

  Next, FIG. 16 is a flowchart showing details of power supply control (B19) of the illumination device / air conditioner shown in FIG. In the power supply control (B19) of the lighting device / air conditioner, the power-off control of the lighting devices 23a to 23c and the air conditioners 24a to 24c shown in FIG.

  In the entrance / exit / exit management device 2, when the employee (user) leaves the room, the corresponding area of the installation area information database (111 in FIG. 9) (the area where the employee (user) has left) is operating ( The number of PCs in the operating state and the number of rooms in the corresponding room number (the room where the employee (user) has left) in the room information database (110 in FIG. 8) are counted down (B3 and B8 in FIG. 15). When the number of visitors in the corresponding room (either 12a or 12b) is 0 (Yes in C1) due to the countdown described above, the basic function unit of the entrance / exit / exit management device 2 (FIG. 6). 101) turns off the lighting device and the air conditioner in the corresponding room (C2). Specifically, when the corresponding room is (12a in FIG. 4), the lighting device (23a in FIG. 4) and the air conditioner (24a in FIG. 4) are turned off. When the corresponding room is (12b in FIG. 4), the lighting device (23b to c in FIG. 4) and the air conditioner (24b to c in FIG. 4) are turned off.

  On the other hand, if the number of people in the corresponding room (either 12a or 12b in FIG. 4) is not 0 (No in C1), the corresponding area (25a in FIG. 4) in the installation area information database (111 in FIG. 9). It is determined whether the number of PCs in operation (operating state) is 0 (any of -c) (C3). When the number of operating (operating) PCs in the corresponding area is 0 (Yes in C3), the basic function unit 101 (101 in FIG. 6) of the entrance / exit / exit management device 2 The lighting device and the air conditioner are turned off (C5). Specifically, when the corresponding area is (25b in FIG. 4), the lighting device (23b in FIG. 4) and the air conditioner (24b in FIG. 4) are turned off. When the corresponding area is (25c in FIG. 4), the lighting device (23c in FIG. 4) and the air conditioner (24c in FIG. 4) are turned off (in addition, the area (25a in FIG. 4) Will be processed later).

  On the other hand, when it is determined No in step C3, after a predetermined time has elapsed (C4), the process returns to step C1 and the process is repeated.

  Next, the effect of the power supply control system 1 according to the first embodiment will be described.

  In the power supply control system 1, the entrance / exit / exit management device (2 in FIG. 4) enters and exits the building (11 in FIG. 4), and the room (11 in FIG. 4) (12a in FIG. 4). 12b), and the power supply control device (4 in FIG. 4) displays the user code C1 output from the entrance / exit / exit management device (2 in FIG. 4) and the entrance / exit / exit room information C2. Is used to control the power supply state of the computer device (18a to 18f in FIG. 4) used by the user who has been successfully authenticated. When the user leaves the building, there is a high possibility that the computer device will not be used for a long period of time. Therefore, the power consumption is reduced by shifting to a power-off state that consumes little power. In addition, when a user leaves the room, there is a possibility of entering the room again and using the computer device, so that the user consumes more power than the power-off state, but shifts to the sleep state where the return time to the operating state is short. ing. As described above, the entrance / exit / exit management device 2 and the power control device 4 cooperate to perform power control according to the user status (entrance, exit, entrance, exit, etc.). . This makes it possible to provide a power supply control system that can contribute to reducing the power consumption of the computer device while ensuring the convenience for the user.

  Further, when leaving the building, the computer apparatus (18a to 18f in FIG. 4) can be surely turned off by the power supply control system 1, so that wasteful power consumption due to forgetting to turn off the power can be eliminated.

  Further, according to the study of the present inventor, when the user leaves the room temporarily, if it is within a certain period of time, including the power consumption to return to the operating state, the sleep state is the power off state. It has been found that there may be less power consumption than the case. For this reason, if the user leaves the room within a certain period of time, the power consumption is reduced and the convenience of the user (such as a short return time to the operating state) can be ensured. .

  In the first embodiment, in addition to power control for the computer devices (18a to 18f in FIG. 4), the entrance / exit / exit management device 2 determines the number of people in each room (12a and 12b in FIG. 4). It is possible to monitor and control the lighting devices (23a to 23c in FIG. 4) and air conditioners (24a to 24c in FIG. 4) installed in the room where the number of people has become 0 to be turned off. Thereby, power consumption in the office can be further reduced. In addition, when the user leaves the room, the lighting devices (23a to c in FIG. 4) and the air conditioner (24a to c in FIG. 4) are automatically turned off, so that the burden on the user can be reduced. . In addition, useless power consumption due to forgetting to turn off the power can be eliminated.

  Furthermore, in the room 12b of FIG. 4, the room is divided into a plurality of areas (25b, 25c), and the lighting devices (23b, 23c) and the air conditioners (24b, 24c) for each area are individually turned on / It is configured to be off. Then, it detects that the number of computer devices whose status is in the operating state among the computer devices installed in each area is 0, and the lighting device (either 23b or 23c) in the corresponding area, air conditioning The device (one of 24b and 24c) is controlled to be turned off. Thus, it becomes possible to further reduce power consumption by controlling the lighting devices (23b, 23c) and the air conditioners (24b, 24c) for each area based on the status of the computer devices 18d to 18f. .

  Note that a hibernation state (also referred to as “hibernation”) may be used instead of the power-off state of the first embodiment. The hibernation state is a power state in which the working state is saved on a hard disk or the like, the operation is temporarily stopped, and power consumption is reduced.

  In the first embodiment, authentication is performed at the time of entering / exiting a building (11 in FIG. 4) and at the time of entering / exiting a room (12a, 12b in FIG. 4) in the building (11 of FIG. 4). However, the present invention is not limited to this. For example, when authentication is performed when entering or leaving a gate in a specific management area (for example, in a factory premises), and when entering or exiting each room of a building in the specific management area, The contents disclosed in the first embodiment can be applied. In this case, an introductory authentication device is installed at the gate of the specific management area (outside the specific management area), and an exit authentication device is installed at the gate of the specific management area (inside the specific management area). The exit management device (equivalent to the entrance / exit management device 2 in FIG. 4) includes an entrance authentication device, an exit authentication device, an entrance authentication device (15a, 15b in FIG. 4), and an exit authentication device (16a in FIG. 4). , 16b) based on the information acquired.

  Each process executed by the control unit 5 of the power supply control device 4 in the embodiment is stored as a program in a storage unit (not shown), and is called and executed by a CPU (Central Processing Unit) provided in the power supply control device 4. Is done. The program can be provided by a (non-transitory) storage medium that stores the program.
