Based on the power transmission completion notification received from the power manager 1, the power reception management unit 43 of the virtual power router 2b at the B home transmits a power transmission completion notification to the user terminal 6b at the B home.

  According to the present embodiment, the power transmission amount from the A home and the power reception amount at the B home are the power transmissions for the combination of the power transmission and reception relations between the home A (transmission power source) and the home B (receiving power source). It is recorded in association with the time and the power reception time. Thereby, the effect that the exchange of the electric power in real time between a specific power transmission (A house) and a receiving power supply (B house) is manageable is acquired.

  The actual power transmission information may further include power transmission position information indicating the power transmission position, and the actual power reception information may further include power reception position information indicating the power reception position. The power transmission / reception record management unit 23 of the power manager 1 collates the power transmission request position notified from the user at the home B of the power receiving power source with the power receiving position indicated by the power receiving position information of the actual power receiving information, for the power transmission / reception related combination. Then, the power transmission approval position notified from the user at home A of the power transmission power source is collated with the power transmission position indicated by the power transmission position information of the actual power transmission information, and the result of the collation is recorded. By using this record, for example, if the verification is successful, the power transmission / reception-related combination is processed free of charge from the home A of the power transmission source to the home B of the power reception source. be able to.

[Power consumption management processing]
Next, power consumption management processing in the power management method according to the present embodiment will be described. 10 and 11 are sequence charts of the power consumption management method according to the present embodiment.

(Step S124) The power consumption management unit 46 of the virtual power router 2b records the operation start time of the operation device with the detected NFC received from the smartphone A_140. The power consumption management unit 46 acquires the user information (the father in the example of FIG. 6) associated with the smartphone A_140 (the detection device 2 in the example of FIG. 6) from the detection device management information held by the device management unit 45. To do. The power consumption management unit 46 associates the acquired user information with the record of the operation device with detection NFC.

(Step S125) The power consumption management unit 46 of the virtual power router 2b inquires of the smart meter 3b about the power value.

(Step S126) The smart meter 3b returns a power value to the power consumption management unit 46 of the virtual power router 2b.

(Step S127) The power consumption management unit 46 of the virtual power router 2b records the power value returned from the smart meter 3b in association with the operation start time of the operation device with detection NFC.

(Step S128) The smartphone A_140 monitors the state of the operating device with the detected NFC.

(Step S129) When the state of the operation device with detection NFC is in operation, the process proceeds to step S130, and when the operation of the operation device with detection NFC is stopped, the process proceeds to step S135.

(Step S130) The smartphone A_140 transmits the operation time of the operation device with the detected NFC to the virtual power router 2b. The process of step S130 is repeatedly performed at regular intervals while the operation of the operation device with the detection NFC continues.

(Step S137) The power consumption management unit 46 of the virtual power router 2b inquires of the smart meter 3b about the power value.

(Step S138) The smart meter 3b returns a power value to the power consumption management unit 46 of the virtual power router 2b.

(Step S139) The power consumption management unit 46 of the virtual power router 2b records the power value responded from the smart meter 3b in association with the operation stop time of the operation device with detection NFC. The power consumption management unit 46 calculates the power consumption of the operation device with detection NFC based on the record of the operation device with detection NFC. The power consumption management unit 46 records the calculated power consumption amount of the operation device with the detected NFC and the user information associated with the recording of the operation device with the detected NFC in association with each other.

12 and 13 are diagrams for explaining the power integration method of the power consumption management unit 46. In the graph of FIG. 12, the horizontal axis represents time, and the vertical axis represents the power value responded from the smart meter 3b. As shown in FIG. 12, when the operating device starts operating (on), the power value responded from the smart meter 3b increases by the usage amount of the operating device. When the operating device stops operating, the power value returned from the smart meter 3b decreases by the amount of use of the operating device. Thereby, the power consumption amount of each operation device is calculated based on the record of each operation device. For example, in FIG. 12, the power consumption of lighting, the power consumption of a personal computer (PC), and the power consumption of a television receiver (TV) are calculated by the following power integration.
Lighting power consumption = (w2-w1) x (t11-t0)
PC power consumption = (w5-w4) x (t9-t2)
TV power consumption = (w4-w2) x (t3-t1) + (w8-w6) x (t10-t7)

  FIG. 13 shows a recording process sequence for a plurality of operating devices. The virtual power router 2b records the time and power value in the power management information storage unit 44 for each operating device. The power consumption management unit 46 calculates the power consumption amount for each operating device based on the record in the power management information storage unit 44.

  According to the present embodiment, since the power consumption is recorded for each operating device, the power consumption of each operating device can be managed. Further, since user information is recorded for each operating device, it is possible to manage which user uses which operating device and how much power is consumed.

  FIG. 14 is a conceptual diagram for explaining the power interchange service according to the present embodiment. In FIG. 14, the parent house (power transmission), the brother's child's house (power reception), and the brother's child (power reception) are a combination of power transmission and reception. According to the present embodiment, for a combination of power transmission / reception relationships between a parent home (power transmission), an older child's home (power reception) and a younger child's home (power reception), the parent home (power transmission) And the amount of power received at each of the brother's child's home (received power supply) and the brother's child's home (received power) are recorded in association with each other based on the power transmission time and the power reception time. By using this record, the amount of power received at each of the brother's child's home (receiving power source) and the brother's child's home (receiving power source) associated with the amount of power transmitted from the parent's home (transmitting power source) is free. The power billing process can be performed. Thereby, for example, it is possible to share, for example, solar power generation in the parent house free of charge to each child house. In addition, when the power supply from the power company is, for example, a maximum of 10 kW instantaneously, and the total power supply amount in three households (parent home and each child home) is 1000 kW per month, By sharing the power, it is possible to flexibly consume the power according to the power consumption of each house.
