Abstract

An appliance located states accumulating method includes the steps of, receiving state information indicating operating state changes of the appliances constituted of a distributed computer through a network, calculating an occurrence time difference from the state changes occurred in the appliances in accordance with occurrence time information indicative of occurrence times of the state changes included in the state information, and calculating the positional relation of the positions, where the appliances occur the state changes, from the calculated occurrence time difference, thereby accumulating the positional relation of the installed appliances.

Claims

1. An appliance located-states accumulating method of accumulating data of a positional relation of individual positions where a plurality of appliances mutually connected through a network are located, comprising:

(a) receiving different classes of state change information from a plurality of different classes of appliances through said network, the state change information being indicative of differing classes of operating state changes of the different classes of appliances;

(b) calculating an occurrence time difference from occurrence times when the differing classes of operating state changes have been detected as having occurred with respect to differing appliances of the differing classes of appliances, in accordance with occurrence time information indicative of occurrence times of the operating state changes included in the state change information; and

(c) acquiring distance between appliances which incur the operating state changes, based on the calculated occurrence time difference;

wherein said acquiring calculates the positional relation in accordance with the occurrence time difference of the operating state changes occurred in two appliances and relationship weight information indicative of a distance between the two appliances; and

wherein said relationship weight information is a value calculated by a predetermined expression in accordance with two elements including;

number of times of occurring the operating state changes; and

the occurrence time difference of the operating state changes occurred in the two appliances.

2. An apparatus cooperative with a plurality of appliances mutually connected through a network and for accumulating data of a positional relation of individual positions where the appliances are located, comprising:

a reception means for receiving different classes of state change information from a plurality of different classes of appliances through said network, the state change information indicating operating state changes of the different classes of appliances,

calculation means calculating an occurrence time difference from occurrence times when the different classes of operating state changes have been detected as having occurred with respect to differing appliances of the differing classes of appliances, in accordance with occurrence time information indicative of occurrence times of the operating state changes included in the state change information; and

acquiring means acquiring a distance between appliances which incur the operating state changes, based on the calculated occurrence time difference;

wherein said acquiring means calculates the positional relation in accordance with the occurrence time difference of the operating state changes occurred in two appliances and relationship weight information indicative of a distance between the two appliances; and

,

wherein said relationship weight information is a value calculated by a predetermined expression in accordance with two elements including;

number of times of occurring the operating state changes; and

the occurrence time difference of the operating state changes occurred in the two appliances.

3. An apparatus according to claim 2, comprising storing means for Storing the occurrence time difference of the operating state changes occurred in the two appliances and the relationship weight information indicative of the distance between the two appliances.

4. A household-appliance located states accumulating method of accumulating data of a positional relation of individual positions where a plurality of household appliances mutually connected throughout a household are located, comprising:

(a) receiving different classes of state change information from a plurality of different classes of appliances through said network, the state change information being indicative of differing classes of operating state changes of the household appliances, where the operating state changes occur responsive to interaction of a person in the household in proximity of ones of the household appliances;

(b) calculating occurrence time differences from occurrence times when the differing classes of operating state changes have been detected as having occurred with respect to differing appliances of the differing classes of appliances, in accordance with occurrence time information indicative of occurrence times of the operating state changes included in the state change information; and

(c) acquiring distance between household appliances which incur the operating state changes in the household, based on the calculated occurrence time differences;

wherein said acquiring calculates the positional relation in accordance with the occurrence time difference of the operating state changes occurred in two appliances and relationship weight information indicative of a distance between the two appliances; and

,

wherein said relationship weight information is a value calculated by a predetermined expression in accordance with two elements including;

number of times of occurring the operating state changes; and

the occurrence time difference of the operating state chances occurred in the two appliances.

5. A system constituted of a plurality of household appliances mutually connected through a network throughout a household, and for accumulating data of a positional relation of individual positions where the household appliances are located in the household, comprising:

a reception means for receiving different classes of state change information from a plurality of different classes of appliances through said network, the state change information indicating differing classes of operating state changes of the different classes of household appliances, where the operating state changes occur responsive to interaction of a person in the household in proximity of the household appliance;

calculation means calculating occurrence time differences from occurrence times when the differing classes of operating state changes have been detected as having occurred with respect to differing appliances of the differing classes of appliances, in accordance with occurrence time information indicative of occurrence times of the operating state changes included in the state change information; and

acquiring means acquiring a distance between household appliances which incur the operating state changes in the household, based on the calculated occurrence time differences;

wherein said acquiring means calculates the positional relation in accordance with the occurrence time difference of the operating state chances occurred in two appliances and relationship weight information indicative of a distance between the two appliances; and

,

wherein said relationship weight information is a value calculated by a predetermined expression in accordance with two elements including;

number of times of occurring the operating state changes; and

the occurrence time difference of the operating state changes occurred in the two appliances.

6. A system according to claim 5, comprising storing means for storing the occurrence time difference of the operating state changes occurred in the two household appliances and the relationship weight information indicative of the distance between the two household appliances.
