Abstract

A power control system is provided with a plurality of electric appliances and a power control apparatus that controls the operation of the plurality of electric devices. The plurality of electric devices are grouped into one or a plurality of groups, each group containing a plurality of electric devices, and on the basis of state information of the electric devices, the power control apparatus controls the operation of each electric device by group according to a plurality of sets of control contents prepared ahead of time.

Claims

1. A power control system, comprising:

a plurality of electric appliances; and

a power control device for controlling operations of the electric appliances,

wherein the electric appliances are assorted into one or more groups each including two or more electric appliances, and the power control device controls operations of the electric appliances on a group-by-group basis according to a plurality of control options prepared in advance based on state information of the electric appliances.

2. The power control system of claim 1, wherein the power control device is configured to change the control options depending on the kind and number of the electric appliances belonging to the same group as the state information.

3. The power control system of claim 1, wherein the groups include a group including a plurality of cooling and heating electric appliances, and wherein the power control device is configured to control the cooling and heating electric appliances in association with each other.

4. The power control system of claim 1, wherein the groups include a human detector for detecting a human existing in a monitoring region and notifying the power control device of presence or absence of the human, and wherein the power control device is configured to control the electric appliances by use of different control options when the human is detected by the human detector and when the human is not detected by the human detector.

5. The power control system of claim 1, wherein the groups include a group to which the electric appliances required to be operated at all times belong.

6. The power control system of claim 5, wherein the power control device is configured to receive a control command from a power company and to reduce power consumption by controlling the electric appliances other than the electric appliances required to be operated at all times, when the control command requests the power control device to reduce power consumption.

7. The power control system of claim 5, wherein the power control device is configured to receive an operation input setting an upper limit value of power consumption and to reduce power consumption by controlling the electric appliances other than the electric appliances required to be operated at all times, when it is determined that the power consumption is likely to exceed the upper limit value.

8. The power control system of claim 1, wherein the power control device is configured to detect failure of the electric appliances by confirming operation states of the electric appliances and releases the group to which the electric appliance under failure belongs upon detecting failure of one of the electric appliances.

9. The power control system of claim 1, wherein the power control device stores, as a threshold value, an average setting value acquired from use history information including use time, use frequency and setting content of the electric appliances and determines disposition of a dweller based on the threshold value to reflect the disposition of the dweller in selecting the control options.

10. The power control system of claim 1, further comprising:

a server device for making data communications with the power control device, wherein, when one of the electric appliances is replaced and identification information thereof is renewed, the power control device transmits the renewed identification information to the server device and acquires performance information of the electric appliance corresponding to the renewed identification information from the server device to change the control options pursuant to the performance information.

11. The power control system of claim 1, further comprising:

a server device for making data communications with the power control device, wherein the power control device transmits identification information of the electric appliances and measured power consumption of the electric appliances to the server device, and wherein the server device finds a statistical value of power consumption on the electric appliance having the same identification information as the identification information received and transmits a warning notice to the power control device if the power consumption received is out of a normal range set pursuant to the statistical value.
