Abstract

An appliance control method is for controlling a target appliance located in a building to disguise the number of people in the building. The method includes: obtaining an operation history of the target appliance (S101); determining a change in the number of people in the building (S102); creating, based on the operation history and the change in the number of people in the building, control patterns each of which is for controlling the target appliance and corresponds to a different one of the numbers of people including the number of people (S103); selecting, from among the created control patterns each of which corresponds to a different one of the numbers of the people, a control pattern which corresponds to the predetermined virtual number of people (S111); and controlling the target appliance according to the selected control pattern (S112).

selecting, from among the created control patterns each of which corresponds to a different one of the numbers of the people, a control pattern which corresponds to the predetermined virtual number of people; and

controlling the target appliance according to the selected control pattern.

2. The appliance control method according to claim 1,

wherein the creating includes creating the control patterns each of which corresponds to a different one of the numbers of the people, by associating an operation detail included in the operation history with the number of people in the building according to the change in the number of people in the building and an operation time included in the operation history.

3. The appliance control method according to claim 1,

wherein the determining includes determining the change in the number of people in the building based on how frequently a user has carried out an operation, the frequency being obtained from the operation history.

4. The appliance control method according to claim 1,

wherein the obtaining includes obtaining operation histories of target appliances located in the building,

the creating includes creating control patterns each of which is for controlling the target appliances and corresponds to a different one of the numbers of the people, and

the controlling includes controlling, according to the selected control pattern, only a target appliance included in the target appliances and located in a target zone which is at least one of zones that are created based on a layout of the building.

5. The appliance control method according to claim 4,

wherein the creating includes creating, for each of the zones, control patterns, each of which corresponds to a different one of the numbers of the people, based on (i) an operation history of a target appliance included in the target appliances and located in the zone and (ii) the change in the number of people in the building, and

the selecting includes selecting a control pattern from among the control patterns each of which corresponds to a different one of the numbers of the people, the selected control pattern corresponding to the predetermined virtual number of the people and the target zone.

6. The appliance control method according to claim 5,

wherein the determining includes determining a change in the number of people in each of the zones, and

the creating includes creating, for each of the zones, control patterns, each of which corresponds to a different one of the numbers of the people, based on (i) an operation history of a target appliance included in the target appliances and located in the zone, and (ii) the change in the number of people in the zone.

7. The appliance control method according to claim 1,

wherein the controlling includes controlling the target appliance in the case where the current number of people in the building is smaller than the predetermined virtual number of the people.

8. The appliance control method according to claim 7,

wherein the obtaining includes obtaining operation histories of target appliances located in the building,

the creating includes creating control patterns each of which is for controlling the target appliances and corresponds to a different one of the numbers of people,

the appliance control method further comprises

in the case where the current number of the people in the building is larger than zero and smaller than the predetermined virtual number of the people, creating a complementary control pattern by extracting a control instruction from among control instructions included in the control pattern that corresponds to the virtual number of the people, the extracted control instruction being sent to a target appliance which is included in the target appliances and has not been operated for a predetermined period in the operation history, and

in the case where the virtual number of the people is larger than the current number of the people in the building, the controlling includes controlling the target appliances according to the complementary control pattern instead of the selected control pattern.

9. The appliance control method according to claim 1,

wherein the obtaining includes obtaining operation histories of appliances located in the building, and

the determining includes determining the change in the number of people in the building based on a time interval between operations on the appliances and locations of the appliances, the operations being obtained from the operation histories.

10. The appliance control method according to claim 9, further comprising

defining the locations of the appliances by (i) comparing the operation histories with a change of power supplied to each of areas in the building and (ii) defining an area, included in the areas, in which each of the appliances is located,

wherein the determining includes determining the change in the number of people in the building based on the defined locations of the appliances.

11. The appliance control method according to claim 1,

wherein the creating includes extracting an operation only from a time unit, among time units, indicating as many operations as a threshold or more, and, based on the extracted operation and the change in the number of people in the building, creating the control patterns each of which corresponds to a different one of the numbers of the people, the time units being included in the operation history and each having predetermined duration, and the control patterns each being created for a different one of the time units.

16. A non-transitory computer-readable recording medium for use in a computer, the recording medium having a computer program recorded thereon for causing a computer to execute the appliance control method according to claim 1.

12. An appliance control apparatus which controls a target appliance located in a building to disguise the number of people in the building, the appliance control apparatus comprising:

an operation history obtaining unit configured to obtain an operation history of the target appliance;

a number-of-people determining unit configured to determine a change in the number of people in the building;
