Abstract

An information processing system includes an obtaining unit, a specifying unit, and an output unit. The obtaining unit obtains information indicating a state of the use of each of plural electrical apparatuses. The specifying unit specifies a power supply-and-receive relationship between the plural electrical apparatuses, on the basis of a change in power associated with the obtained information concerning each of the plural electrical apparatuses. The output unit outputs information indicating the power supply-and-receive relationship.

Claims

1. An information processing system comprising:

an obtaining unit configured to obtain information indicating a state of the use of each of a plurality of electrical apparatuses;

a specifying unit configured to specify a power supply-and-receive relationship between the plurality of electrical apparatuses, on the basis of a change in power associated with the obtained information concerning each of the plurality of electrical apparatuses; and

an output unit configured to output information indicating the power supply-and-receive relationship,

wherein the specifying unit is further configured to determine, concerning a combination of electrical apparatuses having a power supply-and-receive relationship, an electrical apparatus having a larger level of power associated with the obtained information to be an electrical apparatus which supplies power, and determines an electrical apparatus having a smaller level of power associated with the obtained information to be an electrical apparatus which receives power, and

wherein;

the obtaining unit is configured to obtain information indicating power consumed in each of the plurality of electrical apparatuses; and

the specifying unit is configured to specify a power supply-and-receive relationship between the plurality of electrical apparatuses, on the basis of power consumption indicated in the obtained information concerning each of the plurality of electrical apparatuses.

2. The information processing system according to claim 1, wherein the specifying unit specifies, among electrical apparatuses which satisfy a condition that the change in power has reached a predetermined amount, a combination of electrical apparatuses between which a difference in the change in power is contained within a predetermined range, and determines the specified combination of electrical apparatuses to be the combination of electrical apparatuses having a power supply-and-receive relationship.

3. The information processing system according to claim 1, further comprising:

a correcting unit configured to correct at least one of information indicating a time of the use of each of the plurality of electrical apparatuses and information indicating the state of the use of the electrical apparatus at the time of the use of the electrical apparatus,

wherein the obtaining unit obtains the information indicating the time of the use of each of the plurality of electrical apparatuses and the information indicating the state of the use of the electrical apparatus at the time of the use of the electrical apparatus, and the specifying unit specifies a power supply-and-receive relationship between the plurality of electrical apparatuses on the basis of the information corrected by the correcting unit.

4. The information processing system according to claim 2, further comprising:

a correcting unit configured to correct at least one of information indicating a time of the use of each of the plurality of electrical apparatuses and information indicating the state of the use of the electrical apparatus at the time of the use of the electrical apparatus,

wherein the obtaining unit obtains the information indicating the time of the use of each of the plurality of electrical apparatuses and the information indicating the state of the use of the electrical apparatus at the time of the use of the electrical apparatus, and the specifying unit specifies a power supply-and-receive relationship between the plurality of electrical apparatuses on the basis of the information corrected by the correcting unit.

7. The information processing system according to claim 1, wherein the specifying unit is configured to specify the power supply-and-receive relationship between the plurality of electrical apparatuses at a same point in time.

8. The information processing system according to claim 1, wherein the specifying unit is further configured to, in response to a number of the electrical apparatuses exhibiting a change in power consumption being greater than or equal to a predetermined number, updating the power supply-and-receive relationship if a difference between a change in power consumption of a first one of the electrical apparatuses exhibiting a largest power consumption change and a second one of the electrical apparatuses exhibiting a smallest power consumption change, is within a predetermined range.

5. An information processing method comprising:

obtaining information indicating a state of the use of each of a plurality of electrical apparatuses;

specifying a power supply-and-receive relationship between the plurality of electrical apparatuses, on the basis of a change in power associated with the obtained information concerning each of the plurality of electrical apparatuses; and

outputting information indicating the power supply-and-receive relationship,

wherein the specifying determines, concerning a combination of electrical apparatuses having a power supply-and-receive relationship, an electrical apparatus having a larger level of power associated with the obtained information to be an electrical apparatus which supplies power, and determines an electrical apparatus having a smaller level of power associated with the obtained information to be an electrical apparatus which receives power,

wherein the obtaining obtains information indicating power consumed in each of the plurality of electrical apparatuses, and

wherein the specifying specifies a power supply-and-receive relationship between the plurality of electrical apparatuses, on the basis of power consumption indicated in the obtained information concerning each of the plurality of electrical apparatuses.

6. A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:

obtaining information indicating a state of the use of each of a plurality of electrical apparatuses;

specifying a power supply-and-receive relationship between the plurality of electrical apparatuses, on the basis of a change in power associated with the obtained information concerning each of the plurality of electrical apparatuses; and

outputting information indicating the power supply-and-receive relationship,

wherein the specifying determines, concerning a combination of electrical apparatuses having a power supply-and-receive relationship, an electrical apparatus having a larger level of power associated with the obtained information to be an electrical apparatus which supplies power, and determines an electrical apparatus having a smaller level of power associated with the obtained information to be an electrical apparatus which receives power,

wherein the obtaining obtains information indicating power consumed in each of the plurality of electrical apparatuses, and

wherein the specifying specifies a power supply-and-receive relationship between the plurality of electrical apparatuses, on the basis of power consumption indicated in the obtained information concerning each of the plurality of electrical apparatuses.
