Abstract

Used electric energy is collected while maintaining accuracy.

Information to be displayed on a display 14 is generated in such a way that a gateway 4 processes a measured value (with a time stamp) transmitted from a power meter 2, an appliance monitor 5, a solar module 10, and a battery center 13 through a wireless LAN. In the gateway 4, the used electric energy is synchronized with each other by the time stamp. Further, an integrated value of the used electric energy in the time direction is calculated. The information can be secured by obtaining the integrated value of data even if breakdown of devices and the like due to power failure occurs.

Claims

1. A power control device, comprising:

a measuring device configured to measure a flow of power at a plurality of positions in a divided area and to generate a power measured value;

a transmission device configured to add a time stamp to the power measured value from the measuring device and to transmit the power measured value and the time stamp; and

a reception device configured to receive the power measured value and the time stamp from the transmission device,

wherein the reception device calculates an integrated value of the power measured value in a time direction.

2. The power control device according to claim 1, wherein the flow of the power to be measured includes power consumed by an application and power generated by a power generation device.

3. The power control device according to claim 2, wherein the reception device calculates at least one of a total of the power consumed by the application, a total of the generated power, and a difference between the total of the consumed power and the total of the generated power.

4. The power control device according to claim 3, wherein the reception device converts the power into carbon emission strength.

5. The power control device according to claim 3, wherein the reception device transmits the power to an external server through a network, the server stores information of the power, and the information of the power stored in the server is transmitted to the reception device.

6. The power control device according to claim 5, wherein the server converts the information of the power into the carbon emission strength and stores information of the carbon emission strength, and the information of the carbon emission strength stored in the server is transmitted to the reception device.

7. A power control method, comprising the steps of:

measuring a flow of power at a plurality of positions in a divided area and generating a power measured value,

adding a time stamp to the power measured value and transmitting the power measured value and the time stamp;

receiving the power measured value and the time stamp; and

calculating an integrated value of the received power measured value in a time direction.
