For example, in order to prevent forgetting to turn off the television 11 at bedtime, the item of the control setting corresponding to the outlet ID = “D” of the outlet 40D to which the television 11 is connected is set to “turn off the relay at midnight” or the like. Timer information can be set. The power management device 2 switches the relay 51D to the off state when the relay 51D is in the on state at 1 o'clock midnight according to the control setting. Since the information table 55 is displayed on the display device 4, the user who notices that the power of the television 11 is turned off after waking up refers to the contents of the information table 55 displayed on the display device 4. It can be confirmed that the relay 51D is automatically switched to the OFF state in accordance with the control setting of the power management apparatus 2. When the relay 51A connected to the personal computer 8 is switched to the off state by the control setting, the personal computer 8 is normally terminated by remote shutdown before the relay 51A is turned off.

  FIG. 7 is a flowchart illustrating a first example of the activation process of the electrical device by the power management apparatus 2. Here, in a situation where the power of the personal computer 8 and the monitor 9 is off and the relays 51A and 51B are set to the off state, an operation for switching the relay 51A to the on state by the operation of the switch 41A or the remote controller 16 by the user is performed. An example is shown in the case where it is performed or an operation for starting the personal computer 8 is performed by the operation of the remote controller 14 by the user.

  Referring to FIG. 5, when the user presses switch 41A, start signal S2 indicating that is input from switch 41A to control unit 50. When the user transmits a command to switch the relay 51A to the ON state by operating the remote controller 16, a start signal S2 indicating that the command to that effect has been received is input from the receiving unit 42 to the control unit 50. When the user transmits a command to turn on the personal computer 8 by operating the remote controller 14, a start signal S2 indicating that the command to that effect has been received is input from the receiving unit 42 to the control unit 50. The start signal S <b> 2 input to the control unit 50 is transmitted from the PLC transmission unit 54 to the power management apparatus 2.

  Referring to FIG. 3, PLC receiving unit 31 receives start signal S2 from power supply device 3 (step P01 in FIG. 7). The received start signal S2 is input to the control unit 27.

  When the start signal S2 is input, the control unit 27 reads the latest information table 55 held by the management unit 28 as the signal S3 from the management unit 28, and the cooperative relationship is established between the relay 51A and the relay 51A. It is determined whether each set relay 51B is set to an on state or an off state (step P02).

  When relays 51A and 51B are set to the off state (that is, when the determination result in step P02 is “YES”), control unit 27 then switches the switching signal for switching relays 51A and 51B to the on state. S4 is input to the PLC transmission unit 32. The PLC transmission unit 32 transmits the switching signal S4 input from the control unit 27 to the power supply device 3 (step P03). When the relays 51A and 51B are set to the ON state (that is, when the determination result at Step P02 is “NO”), the processing at Step P03 and Step P04 described later is performed for the relays 51A and 51B in the ON state. Is not executed, and the process of step P05 described later is executed.

  Referring to FIG. 5, PLC receiving unit 53 receives switching signal S <b> 4 from power management device 2. Then, the received switching signal S4 is input to the control unit 50. The controller 50 switches the relays 51A and 51B to the on state by the switching signal S4.

  Referring to FIG. 3, control unit 27 that has output switching signal S4 determines whether or not relays 51A and 51B are switched to the on state (step P04). When the switching of the relays 51A and 51B to the ON state is completed, a completion signal S5 is transmitted from the power supply device 3 to the power management device 2, and the PLC receiving unit 31 receives the completion signal S5 and receives the completion signal S5. To enter. The control unit 27 determines that the relays 51 </ b> A and 51 </ b> B are switched to the on state when the completion signal S <b> 5 is input from the PLC receiving unit 31. The determination in step P04 is repeated until the completion signal S5 is input. When the relays 51A and 51B are switched to the on state, in the data S1 that the PLC receiving unit 31 periodically receives from the power supply device 3 with polling, the information indicating the state of the relays 51A and 51B is changed from the off state. Changed to the on state. Thereby, the contents of the information table 55 held by the management unit 28 are updated. Therefore, the control unit 27 can also determine that the relays 51A and 51B have been switched on based on the latest information table 55 read out as the signal S3 from the management unit 28.

  When relays 51A and 51B are switched on (that is, when the determination result in step P04 is “YES”), control unit 27 then starts activation signal S6 for activating personal computer 8 and monitor 9. Is input to the LAN transmitter 34. The LAN transmitter 34 transmits the activation signal S6 input from the controller 27 to the personal computer 8 and the monitor 9 (step P05). The personal computer 8 is activated by receiving the activation signal S6. For example, a magic packet describing the MAC address of the personal computer 8 registered in advance in the storage unit 21 is broadcasted to the LAN 12 so that the personal computer 8 that has received the magic packet can be remotely transmitted by WoL (Wake on LAN). Can be activated. Similarly, the monitor 9 is activated by receiving the activation signal S6 for the monitor 9 transmitted from the power management apparatus 2.

  In the above example, the personal computer 8, the monitor 9, the printer 10, and the television 11 are connected to the outlets 40A to 40D of the power supply device 3 installed in the user's home. In the personal computer room or the like, a plurality of personal computers are centrally managed, and the personal computer 8 may be connected to all the outlets 40A to 40D. Then, when starting all the personal computers 8 for maintenance, etc., when all the switches 41A to 41D are pressed by the operator, a start signal S2 to that effect is collectively (for example, as one packet data). It is transmitted from the power supply device 3 to the power management device 2. Alternatively, a button for switching all the relays 51 </ b> A to 51 </ b> D to an on state is prepared on the remote controller 16, and when the operator presses the button, a start signal S <b> 2 indicating that is sent to the power supply device 3. To the power management device 2. In such a case, the power management device 2 collectively transmits a switching signal S4 for switching the relays 51A to 51D to the ON state to the power supply device 2, and the relays 51A to 51D to be turned ON. After the switching is completed, the activation signal S6 is transmitted to all the personal computers 8 at once. As a result, all the personal computers 8 are activated in a lump simply by operating the switches 41A to 41D or the remote controller 16, so that the user's work burden can be greatly reduced.

  FIG. 8 is a flowchart showing a second example of the activation process of the electric device by the power management apparatus 2. Here, in the situation where the power of the personal computer 8 is off, the relay 51A is off, and the relay 51B is on, an operation for starting the personal computer 8 by a remote login operation from the remote personal computer 7 is performed. An example in the case where is performed is shown. The remote login operation can be performed not only from the personal computer 7 but also from an arbitrary terminal such as a mobile phone or a portable information terminal.

  Referring to FIG. 3, WAN receiving unit 29 receives a remote login command to personal computer 8 as start signal S2 from personal computer 7 via communication network 6 and home gateway 5 (step P11 in FIG. 8). The received start signal S2 is input to the control unit 27.

  When the start signal S2 is input, the control unit 27 reads the latest information table 55 held by the management unit 28 as the signal S3 from the management unit 28, and the relay 51A (and the relay 51B in a cooperative relationship) is turned on. It is determined whether it is set to the state or the off state (step P12).

  If relay 51A is set in the off state (that is, if the determination result in step P12 is “YES”), then control unit 27 performs PLC transmission of switching signal S4 for switching relay 51A to the on state. Input to the unit 32. The PLC transmission unit 32 transmits the switching signal S4 input from the control unit 27 to the power supply device 3 (step P13).

  Referring to FIG. 5, PLC receiving unit 53 receives switching signal S <b> 4 from power management device 2. Then, the received switching signal S4 is input to the control unit 50. Control unit 50 switches relay 51A to the ON state by switching signal S4.

  Referring to FIG. 3, the control unit 27 that has output the switching signal S4 switches the relay 51A to the ON state based on the completion signal S5 or the latest information table 55, as in step P04 of the first example. It is determined whether or not it has been (step P14).

  When relay 51A is switched on (that is, when the determination result in step P14 is “YES”), control unit 27 then sends activation signal S6 for activating personal computer 8 to LAN transmission unit 34. To enter. The LAN transmitter 34 transmits the activation signal S6 input from the controller 27 to the personal computer 8 (step P15). The personal computer 8 is activated by receiving the activation signal S6.

  Next, the control unit 27 that has output the activation signal S6 determines whether or not the personal computer 8 has been normally activated (step P16). When the personal computer 8 is activated, the amount of power supplied from the outlet 40 </ b> A to the personal computer 8 increases in the data S <b> 1 that the PLC receiving unit 31 periodically receives from the power supply device 3 along with polling. Thereby, the contents of the information table 55 held by the management unit 28 are updated. Therefore, the control unit 27 can determine that the personal computer 8 has been normally activated based on the latest information table 55 read as the signal S3 from the management unit 28.

  When the personal computer 8 is normally activated (that is, when the determination result in step P16 is “YES”), the control unit 27 then outputs a report signal S7 indicating that the activation process of the personal computer 8 has been normally completed. , Input to the WAN transmitter 30. The WAN transmitter 30 transmits the input report signal S7 to the personal computer 7 via the home gateway 5 and the communication network 6 (step P17).

  On the other hand, when the relay 51A is not switched on within a predetermined time (for example, several minutes) after the control unit 27 outputs the switching signal S4 (that is, when the determination result in step P14 is “NO”). The control unit 27 inputs a report signal S7 indicating that the switching process of the relay 51A is abnormal to the WAN transmission unit 30. Further, when the personal computer 8 is not started within a predetermined time (for example, several minutes) after the control unit 27 outputs the start signal S6 (that is, when the determination result in step P16 is “NO”), the control unit 27 inputs a report signal S7 indicating that the startup process of the personal computer 8 is abnormal to the WAN transmitter 30. The WAN transmitter 30 transmits the input report signal S7 to the personal computer 7 via the home gateway 5 and the communication network 6 (step P18).

When the user transmits a command to switch the relay 51 </ b> A to the OFF state by operating the remote controller 16, an end signal S <b> 8 indicating that the command to that effect has been received is input from the receiving unit 42 to the control unit 50. The end signal S8 input to the control unit 50 is transmitted from the PLC transmission unit 54 to the power management apparatus 2.

  Referring to FIG. 3, PLC receiving unit 31 receives end signal S8 from power supply device 3 (step P21 in FIG. 9). The received end signal S8 is input to the control unit 27.

  When the end signal S8 is input, the control unit 27 sends an end signal S10 for ending the operation of the personal computer 8 and the monitor 9 for which the cooperative relationship with the personal computer 8 is set to the LAN transmission unit 34. input. The LAN transmitter 34 transmits the end signal S10 input from the controller 27 to the personal computer 8 and the monitor 9 (step P22). The personal computer 8 that has received the end signal S10 ends its operation by remote shutdown. Similarly, by receiving the end signal S10 for the monitor 9 transmitted from the power management device 2, the monitor 9 ends its operation.

  Next, the control unit 27 that has output the end signal S10 determines whether or not the operations of the personal computer 8 and the monitor 9 have ended (step P23). When the operations of the personal computer 8 and the monitor 9 are finished, the data S1 periodically received by the PLC receiver 31 from the power supply device 3 along with polling is supplied from the relay 51A and the relay 51B to the personal computer 8 and the monitor 9, respectively. The amount of power decreases. Thereby, the contents of the information table 55 held by the management unit 28 are updated. Therefore, the control unit 27 can determine that the operations of the personal computer 8 and the monitor 9 have ended based on the latest information table 55 read out as the signal S3 from the management unit 28.

  When the operations of the personal computer 8 and the monitor 9 are completed (that is, when the determination result in step P23 is “YES”), the control unit 27 then switches the switching signal S4 for switching the relays 51A and 51B to the off state. Is input to the PLC transmission unit 32. The PLC transmission unit 32 transmits the switching signal S4 input from the control unit 27 to the power supply device 3 (step P24).

  Referring to FIG. 5, PLC receiving unit 53 receives switching signal S <b> 4 from power management device 2. Then, the received switching signal S4 is input to the control unit 50. The control unit 50 switches the relays 51A and 51B to the off state by the switching signal S4.

  FIG. 10 is a flowchart illustrating a second example of the end process of the electrical device by the power management apparatus 2. Here, when the personal computer 8 and the monitor 9 are turned on and the relays 51A and 51B are set to the on state, an operation for remotely shutting down the personal computer 8 from the remote personal computer 7 is performed. An example is shown.

  Referring to FIG. 3, WAN receiving unit 29 receives a remote shutdown command for personal computer 8 from personal computer 7 via communication network 6 and home gateway 5 as end signal S8 (step P31 in FIG. 10). The received end signal S8 is input to the control unit 27.

  When the end signal S8 is input, the control unit 27 sends an end signal S10 for ending the operation of the personal computer 8 and the monitor 9 for which the cooperative relationship with the personal computer 8 is set to the LAN transmission unit 34. input. The LAN transmitter 34 transmits the end signal S10 input from the controller 27 to the personal computer 8 and the monitor 9 (step P32). The personal computer 8 that has received the end signal S10 ends its operation by remote shutdown. Similarly, by receiving the end signal S10 for the monitor 9 transmitted from the power management device 2, the monitor 9 ends its operation.

  Next, the control unit 27 that has output the end signal S10 determines whether or not the operation of the personal computer 8 and the monitor 9 has ended (step P33). When the operation of the personal computer 8 and the monitor 9 is normally completed, the data is periodically supplied from the relay 51A and the relay 51B to the personal computer 8 and the monitor 9 in the data S1 that the PLC receiving unit 31 periodically receives from the power supply device 3 along with the polling. The amount of power used is reduced. Thereby, the contents of the information table 55 held by the management unit 28 are updated. Therefore, the control unit 27 can determine that the operations of the personal computer 8 and the monitor 9 have ended based on the latest information table 55 read out as the signal S3 from the management unit 28.

  When the operations of the personal computer 8 and the monitor 9 are completed (that is, when the determination result in step P33 is “YES”), the control unit 27 then switches the switching signal S4 for switching the relays 51A and 51B to the off state. Is input to the PLC transmission unit 32. The PLC transmission unit 32 transmits the switching signal S4 input from the control unit 27 to the power supply device 3 (step P34).

  Referring to FIG. 5, PLC receiving unit 53 receives switching signal S <b> 4 from power management device 2. Then, the received switching signal S4 is input to the control unit 50. The control unit 50 switches the relays 51A and 51B to the off state by the switching signal S4.

  Referring to FIG. 3, control unit 27 that has output switching signal S4 determines whether or not relays 51A and 51B are switched to the off state (step P35). When the switching of the relays 51A and 51B to the off state is completed, a completion signal S5 is transmitted from the power supply device 3 to the power management device 2, and the PLC receiving unit 31 receives the completion signal S5 and receives the completion signal S5. To enter. The control unit 27 determines that the relays 51 </ b> A and 51 </ b> B are switched to the off state when the completion signal S <b> 5 is input from the PLC receiving unit 31. When the relays 51A and 51B are switched to the off state, in the data S1 that the PLC receiving unit 31 periodically receives from the power supply device 3 with polling, the information indicating the state of the relays 51A and 51B is changed from the on state. Changed to off state. Thereby, the contents of the information table 55 held by the management unit 28 are updated. Therefore, the control unit 27 can also determine that the relays 51A and 51B are switched to the OFF state based on the latest information table 55 read out as the signal S3 from the management unit 28.

  When relays 51A and 51B are switched to the off state (that is, when the determination result in step P35 is “YES”), control unit 27 then reports that the termination processing of personal computer 8 has been completed normally. The signal S7 is input to the WAN transmission unit 30. The WAN transmitter 30 transmits the input report signal S7 to the personal computer 7 via the home gateway 5 and the communication network 6 (step P36).

  On the other hand, when the personal computer 8 is not terminated within a predetermined time (for example, several minutes) after the control unit 27 outputs the end signal S10 (that is, when the determination result in step P33 is “NO”), the control unit 27 inputs a report signal S7 indicating that the termination process of the personal computer 8 is abnormal to the WAN transmitter 30. Further, when the relay 51A is not switched to the OFF state within a predetermined time (for example, several minutes) after the control unit 27 outputs the switching signal S4 (that is, when the determination result in step P35 is “NO”). The control unit 27 inputs a report signal S7 indicating that the switching process of the relay 51A is abnormal to the WAN transmission unit 30. The WAN transmitter 30 transmits the input report signal S7 to the personal computer 7 via the home gateway 5 and the communication network 6 (step P37).

  According to the power management apparatus 2 and the power management system 1 according to the present embodiment, when the control unit 27 receives the start signal S2 for switching the relay 51A set to the off state to the on state, A switching signal S4 for switching the relay 51A to the ON state is transmitted to the power supply device 2, and after the switching of the relay 51A to the ON state is completed, the starting signal for starting the personal computer 8 connected to the relay 51A S6 is transmitted to the personal computer 8. Similarly, when the control unit 27 receives a start signal S2 for activating the personal computer 8 connected to the relay 51A set to the off state, the control unit 27 switches the relay 51A to the on state. S4 is transmitted to the power supply device 2, and after the switching of the relay 51A to the ON state is completed, an activation signal S6 for activating the personal computer 8 connected to the relay 51A is transmitted to the personal computer 8. Accordingly, an operation of manually turning on the switch 41A of the outlet 40A by the user, an operation of turning on the relay 51A with the remote control 16 of the power supply device 3, an operation of turning on the power of the personal computer 8 with the remote control 14 of the personal computer 8, or When the remote login operation of the personal computer 8 is performed from the external personal computer 7 through the communication network 6, the process of switching the relay 51 </ b> A to the ON state and the process of starting the personal computer 8 are controlled by the control unit 27. Automatically executed. Therefore, since the necessary operation when starting up the personal computer 8 is simplified, the troublesomeness of the operation given to the user can be reduced. As a result, it is possible to achieve the original purpose of avoiding standby power consumption by reducing the possibility of misuse of not turning off the outlet even when the electrical equipment is turned off. It becomes.

  In addition, according to the power management apparatus 2 and the power management system 1 according to the present embodiment, the control unit 27 switches one relay 51A out of the relays 51A and 51B for which the cooperative relationship is set to the on state. When the start signal S2 is received, a switching signal S4 for switching both relays 51A and 51B to the ON state is transmitted to the power supply device 3, and after the switching of the relays 51A and 51B to the ON state is completed Then, an activation signal S6 for activating the personal computer 8 and the monitor 9 connected to the relays 51A and 51B is transmitted to the personal computer 8 and the monitor 9. Similarly, when the start signal S2 for starting the personal computer 8 of the personal computer 8 and the monitor 9 for which the cooperative relationship is set to the relays 51A and 51B is received, the relay is connected to the personal computer 8 and the monitor 9. A switching signal S4 for switching both of the relays 51A and 51B to the ON state is transmitted to the power supply device 3, and after the switching of the relays 51A and 51B to the ON state is completed, the personal computer 8 and the monitor 9 are started. An activation signal S6 is transmitted to the personal computer 8 and the monitor 9. Accordingly, for the personal computer 8 out of the personal computer 8 and the monitor 9 that are linked, the user performs an operation of manually turning on the switch 41A of the outlet 40A, so that the relay 51A, The process of switching 51B to the on state and the process of starting the personal computer 8 and the monitor 9 are automatically executed under the control of the control unit 27. Therefore, since the necessary operation when starting two or more electric devices in a cooperative relationship is greatly simplified, the troublesomeness of the operation given to the user can be greatly reduced.

  Further, according to the power management device 2 and the power management system 1 according to the present embodiment, the WAN transmission unit 30 (transmission means) is transmitted by the measurement unit 52A after the control unit 27 transmits the switching signal S4 and the activation signal S6. Based on the measured electric energy, a report signal S7 indicating whether or not the startup process of the personal computer 8 has been normally executed is transmitted to the personal computer 7. When the personal computer 8 that is in the off state is activated, the amount of power supplied from the power supply device 3 to the personal computer 8 increases. Therefore, the startup process of the personal computer 8 is normally executed by measuring the amount of power. It is possible to accurately determine whether or not it has been done. And the user who transmitted start signal S2 from the remote personal computer 7 can confirm whether the starting process of the personal computer 8 was normally performed by receiving report signal S7 from the power management apparatus 2.

  Moreover, according to the power management apparatus 2 and the power management system 1 according to the present embodiment, the WAN transmission unit 30 is configured to measure the power measured by the measurement unit 52A after the control unit 27 transmits the end signal S10 and the switching signal S4. Based on the amount, a report signal S7 indicating whether or not the termination process of the personal computer 8 has been normally executed is transmitted to the personal computer 7. When the operation of the personal computer 8 that is in the ON state is terminated, the amount of power supplied from the power supply device 3 to the personal computer 8 decreases, and therefore the termination process of the personal computer 8 is normal by measuring the amount of power. It is possible to accurately determine whether or not it has been executed. Then, the user who has transmitted the end signal S8 from the remote personal computer 7 can confirm whether or not the end processing of the personal computer 8 has been normally executed by receiving the report signal S7 from the power management apparatus 2. .

  Further, according to the power supply device 3 according to the present embodiment, the reception unit 42 (reception unit) receives the start signal S2 for switching the relay 51A to the on state or starting the personal computer 8, The PLC transmission unit 54 (transmission means) transmits the start signal S2 received by the reception unit 42 to the power management apparatus 2.

Similarly, when the start signal S2 for starting the personal computer 8 connected to the relay 51A set to the off state is received from the power supply device 3, the switching signal for switching the relay 51A to the on state. After S4 is transmitted to the power supply device 2 and the switching of the relay 51A to the ON state is completed, an activation signal S6 for activating the personal computer 8 connected to the relay 51A can be transmitted to the personal computer 8. Therefore, when the user performs an operation of switching the relay 51A to the on state with the remote controller 16 of the power supply device 3 or an operation of turning on the power of the personal computer 8 with the remote controller 14 of the personal computer 8, the relay 51A is turned on. The process of switching and the process of starting up the personal computer 8 are automatically executed under the control of the control unit 27. Therefore, since the necessary operation when starting up the personal computer 8 is simplified, the troublesomeness of the operation given to the user can be reduced. As a result, it is possible to achieve the original purpose of avoiding standby power consumption by reducing the possibility of misuse of not turning off the outlet even when the electrical equipment is turned off. It becomes.
