<Specific examples of power supply management>
Next, a specific example of power supply management will be described with reference to FIGS. 3 and 4. 3 is a diagram showing an example in which various devices are connected to the first tap system TS1 according to the present embodiment, and FIG. 4 is a diagram in which various devices are connected to the second tap system TS2 according to the present embodiment. It is the figure which showed the example.

<First tap system TS1>

The DVD Player power cable is connected to the dual-purpose outlet SC12 that has been switched to the normal outlet. In the first extension tap ET1, the TV Game 2 power cable is connected to the dual-purpose outlet SC13 switched to the slave outlet, and the TV Game 1 power cable is connected to the dual-purpose outlet SC 14 switched to the slave outlet. Yes. Other outlets are not used.

  In this example, the master power amount measuring means 20 of the first master tap MT1 measures the power consumption amount of the CATV Tuner connected to the master outlet MC1, and the master power amount determining means 22 is the master power amount measuring means 20. It is determined whether or not the power consumption measured by the above exceeds a predetermined threshold. Here, the power consumption of the CATV Tuner is 5 W (standby power) when the power is off, 50 W when the power is on, and the threshold of the power consumption that is the criterion of the master power amount judging means 22 is 10 W. Consider the case where it is set.

<Powering on CATV Tuner>
When the power of the CATV Tuner is switched from OFF to ON, the power consumption of the CATV Tuner changes from 5 W to 50 W. Therefore, the master power determination unit 22 uses the consumption of the CATV Tuner measured by the master power measurement unit 20. It is determined that the amount of power has exceeded a predetermined threshold (in this example, 10 w), and information (for example, a numerical value of 1) indicating that the threshold has been exceeded is stored in the storage unit 18 as a power determination result. In addition, the transmission unit 24 performs a process of transmitting the power determination result stored in the storage unit 18 (in this example, information indicating that the power consumption exceeds the threshold) toward the first extension tap ET1.

  Next, the master tap power control means 34 performs power control to be supplied from the dual-purpose outlet SC according to the power determination result stored in the storage means 18, but the dual-purpose outlet SC11 is switched to a slave outlet and the power Since the determination result indicates that the threshold value is exceeded, by permitting power supply from the dual-purpose outlet SC11, a process of supplying power to the TV connected to the dual-purpose outlet SC11 is performed. As a result, power is supplied to the TV connected to the dual-purpose outlet SC11 in conjunction with the power-on of the CATV Tuner, and the TV is automatically turned on if the power switch of the TV main body is on.

  On the other hand, since the dual-purpose outlet SC12 is switched to the normal outlet, the power supply from the dual-purpose outlet SC12 is permitted regardless of the power determination result, so that the DVD player connected to the dual-purpose outlet SC12 can be connected. Processing to supply power is performed. As a result, power is always supplied to the DVD player connected to the dual-purpose outlet SC12 regardless of whether the CATV Tuner is turned on. That is, the power-on state is maintained if the power switch of the DVD Player main body is on, and the power-off state is maintained if the power switch is off.

  Next, the receiving means 40 of the first extended tap ET1 receives the power determination result (information indicating that the power consumption amount exceeds the threshold value) transmitted from the transmitting means 24 of the first master tap MT1. Perform the process. The extended tap power control means 44 performs power control supplied from the dual-purpose outlet SC according to the power determination result received by the reception means 40. The dual-purpose outlets SC13 and SC14 are switched to slave outlets and Since the determination result indicates that the threshold value is exceeded, by permitting the power supply from the shared outlets SC13 and SC14, the TV Game2 connected to the shared outlet SC13 and the TV Game1 connected to the shared outlet SC14 are displayed. The process of supplying power to is performed. As a result, power is supplied to the TV Game 2 connected to the dual-purpose outlet SC13 and the TV Game 1 connected to the dual-purpose outlet SC14 in conjunction with the power-on of the CATV Tuner, and the power switch of each device is in the ON state. Each device is automatically turned on.

  Next, the slave power amount measuring means 30 of the first master tap MT1 calculates the power consumption of the TV connected to the dual-purpose outlet (slave outlet) SC11. Further, the transmission unit 24 stores information including the power consumption amount of the CATV Tuner measured by the master power amount measurement unit 20 and the power consumption amount of the TV measured by the slave power amount measurement unit 30 in the first extension tap ET1.

  On the other hand, the slave power amount measuring means 30 of the first extension tap ET1 includes the power consumption amount of the TV Game2 connected to the dual-purpose outlet (slave outlet) SC13 and the consumption of the TV Game1 connected to the dual-purpose outlet (slave outlet) SC14. Calculate the amount of power. Further, the first extension tap ET1 includes the CATV Tuner power consumption and TV power consumption acquired from the first master tap MT1, and the TV Game2 power consumption and TV Game1 calculated by the slave power amount measuring means 30. The total power consumption and the electricity bill are calculated. The electricity charge can be calculated by multiplying the calculated total power consumption by an electricity charge per power consumption (for example, 2.1 yen per 1 W / h).

  In this example, the first extended tap ET1 acquires the information on the power consumption from the first master tap MT1 and calculates the total power consumption and the electricity charge. However, the first master tap MT1 The information of the power consumption amount may be acquired from the first extension tap ET1, and the total power consumption amount and the electricity charge may be calculated, or an external device may use the first master tap MT1 or the first extension tap via wireless communication. Information on the power consumption amount may be acquired from ET1, and the total power consumption amount and the electricity charge may be calculated (the same applies to the second tap system TS2).

  In addition, a display unit (for example, an LED or a liquid crystal display device) capable of displaying the calculated total power consumption or electricity charge may be provided, or the calculated total power consumption or electricity charge may be transmitted to the outside by wireless communication. Alternatively, it may be displayed on an external PC.

<Power off of CATV Tuner>
When the power of the CATV Tuner is switched from ON to OFF, the power consumption of the CATV Tuner changes from 50 W to 5 W. Therefore, the master power amount determination means 22 uses the consumption of the CATV Tuner measured by the master power amount measurement means 20. A process of determining that the amount of power is equal to or less than a predetermined threshold (in this example, 10 w) and storing information indicating that the amount of power is equal to or less than the threshold (for example, numerical value 0) in the storage unit 18 as a power determination result. Do. Further, the transmission unit 24 performs a process of transmitting the power determination result stored in the storage unit 18 (in this example, information indicating that the power consumption is equal to or less than the threshold value) toward the first extension tap ET1. .

  Next, the master tap power control means 34 performs power control to be supplied from the dual-purpose outlet SC according to the power determination result stored in the storage means 18, but the dual-purpose outlet SC11 is switched to a slave outlet and the power Since the determination result indicates that it is equal to or less than the threshold value, the power supply to the TV connected to the dual-purpose outlet SC11 is cut off by prohibiting the power supply from the dual-purpose outlet SC11. Thereby, in conjunction with the power-off of the CATV Tuner, the power of the TV connected to the dual-purpose outlet SC11 is automatically turned off (standby state).

  On the other hand, since the dual-purpose outlet SC12 is switched to the normal outlet, the power supply from the dual-purpose outlet SC12 is permitted regardless of the power determination result, so that the DVD player connected to the dual-purpose outlet SC12 can be connected. Processing to supply power is performed. Thus, power is supplied to the DVD player connected to the dual-purpose outlet SC12 regardless of the power-off of the CATV tuner. That is, the power-on state is maintained if the power switch of the DVD Player main body is on, and the power-off state is maintained if the power switch is off.

  Next, the receiving means 40 of the first extended tap ET1 sends the power determination result (information indicating that the power consumption amount is equal to or less than the threshold value) transmitted from the transmitting means 24 of the first master tap MT1. Process to receive. The extended tap power control means 44 performs power control supplied from the dual-purpose outlet SC according to the power determination result received by the reception means 40. The dual-purpose outlets SC13 and SC14 are switched to slave outlets and Since the determination result indicates that the threshold value is exceeded, by prohibiting power supply from the dual-purpose outlets SC13 and SC14, the TV Game2 connected to the dual-purpose outlet SC13 and the TV Game1 connected to the dual-purpose outlet SC14 are displayed. Processing to cut off the power of. Thereby, in conjunction with the power-off of the CATV Tuner, the power of the TV Game 2 connected to the shared outlet SC13 and the power of the TV Game 1 connected to the shared outlet SC14 are turned off.

<Second tap system TS2>
As shown in FIG. 4, in this example, in the second master tap MT2, a PC (personal computer) power cable is connected to the master outlet MC2, and the dual outlet SC21 switched to the normal outlet is connected to the ROUTER (router). ) Power cable is connected. In the second extension tap ET2, the HDD (hard disk) power cable is connected to the dual-purpose outlet SC22 switched to the slave outlet.

  In this example, the master power amount measuring means 20 of the second master tap MT2 measures the power consumption amount of the PC connected to the master outlet MC2, and the master power amount determining means 22 is measured by the master power amount measuring means 20. It is determined whether or not the consumed power amount exceeds a predetermined threshold value. Here, the power consumption of the PC is 3 W (standby power) when the power is off, 25 W when the power is on, and the threshold of the power consumption that is the criterion of the master power amount judging means 22 is set to 8 W. Consider the case.

<PC power on>
When the power of the PC is switched from OFF to ON, the power consumption of the PC changes from 3 W to 25 W. Therefore, the master power amount determination unit 22 determines that the power consumption of the PC measured by the master power amount measurement unit 20 is the same. It is determined that a predetermined threshold value (8w in this example) has been exceeded, and information (for example, a numerical value 1) indicating that the threshold value has been exceeded is stored in the storage unit 18 as a power determination result. Further, the transmission unit 24 performs a process of transmitting the power determination result stored in the storage unit 18 (in this example, information indicating that the power consumption amount exceeds the threshold value) toward the second extension tap ET2.

  In the present embodiment, the information transmitted from the transmission unit 24 of the first master tap MT1 is configured to be received only by the reception unit 40 of the first extension tap ET1, and the reception unit of the second extension tap ET2 40 is configured not to be able to receive. Conversely, the information transmitted from the transmission means 24 of the second master tap MT2 is configured to be received only by the reception means 40 of the second extension tap ET2, and is received by the reception means 40 of the first extension tap ET1. Is configured not to receive. That is, the first tap system TS1 and the second tap system TS2 are independent systems.

  Next, the master tap power control unit 34 performs power control supplied from the dual-purpose outlet SC according to the power determination result stored in the storage unit 18, but for the dual-purpose outlet SC21, the dual-purpose outlet SC is switched to a normal outlet. Therefore, the process of supplying power to the ROUTER connected to the shared outlet SC21 is performed by permitting the power supply from the shared outlet SC21 regardless of the power determination result. As a result, power is supplied to the ROUTER connected to the dual-purpose outlet SC21 regardless of whether the PC is turned on. That is, the power-on state is maintained if the switch of the ROUTER main body is on, and the power-off state is maintained if the switch is off.

  Next, the receiving means 40 of the second extension tap ET2 receives the power determination result (in this example, information indicating that the power consumption exceeds the threshold) transmitted from the transmitting means 24 of the second master tap MT2. Perform the process. The extended tap power control unit 44 performs power control supplied from the dual-purpose outlet SC according to the power determination result received by the reception unit 40. The dual-purpose outlet SC22 is switched to a slave outlet and the power determination result Indicates that the threshold value exceeds the threshold value, the power supply to the HDD connected to the dual-purpose outlet SC22 is performed by permitting the power supply from the dual-purpose outlet SC22. Thus, in conjunction with the power-on of the PC, power is supplied to the HDD connected to the dual-purpose outlet SC22. If the power switch of the HDD main body is on, the power of the HDD is automatically turned on.

  Next, the transmission unit 24 performs processing for transmitting information including the power consumption amount of the PC calculated by the master power amount measurement unit 20 toward the second extension tap ET2. On the other hand, the slave power amount measuring means 30 of the second extension tap ET2 calculates the power consumption amount of the HDD connected to the dual-purpose outlet (slave outlet) SC22. The second extension tap ET2 adds up the PC power consumption obtained from the second master tap MT2 and the HDD power consumption calculated by the slave power measurement means 30 to obtain the total power consumption and the electricity bill. Is calculated.

<PC power off>
When the power supply of the PC is switched from on to off, the power consumption of the PC changes from 25 W to 3 W. Therefore, the master power consumption measuring unit 20 determines that the power consumption of the PC measured by the master power measurement unit 20 is the same. It is determined that the predetermined threshold value (8w in this example) has been reached or less, and information (for example, a numerical value of 0) indicating that the threshold value has been reached or less is stored in the storage unit 18 as a power determination result. The transmission unit 24 performs a process of transmitting the power determination result stored in the storage unit 18 (in this example, information indicating that the power consumption amount is equal to or less than the threshold) toward the second extension tap ET2. .

  Next, the master tap power control unit 34 performs power control supplied from the dual-purpose outlet SC according to the power determination result stored in the storage unit 18, but for the dual-purpose outlet SC21, the dual-purpose outlet SC is switched to a normal outlet.
