Abstract

An object of the present invention is to provide a control device and the like that controls home electrical appliances via a communication line by using function codes which are set without being specialized for specific home electrical appliances. This object is achieved by a home electrical appliance control device that controls a home electrical appliance connected via a communication line, comprising: a memory section for storing a function table for mapping function identifiers, which identify function types allocated with the focus on the function itself to functions with which the home electrical appliance is equipped, with attributes of the functions; and a control section for controlling the home electrical appliance via the communication line on the basis of the function table.

Claims

1. A home electrical appliance control device that controls a home electrical appliance connected via a communication line, said control device comprising:

a memory section for storing a function table for mapping function identifiers, which identify function types allocated to functions of the home electrical appliance based solely on said functions regardless of kinds of the home electrical appliances, with attributes of the functions; and

a control section for controlling the home electrical appliance via the communication line on the basis of said function table.

2. The home electrical appliance control device according to claim 1, further comprising a storage section for generating built-in function information that associates the function identifier and the home electrical appliance on the basis of the received built-in function notice in case that a built-in function notice including a function identifier corresponding to a function of the home electrical appliance is received from the home electrical appliance and for storing said built-in function information in the memory section.

3. The home electrical appliance control device according to claim 2, wherein the control section retrieves the function identifier which corresponds to the function to be controlled from the function table and transmits the function identifier together with information that an inquiry on the state of the function is to be performed to the home electrical appliance which corresponds to the function identifier retrieved by making reference to the built-in function information.

4. The home electrical appliance control device according to claim 2, wherein the control section retrieves the function identifier which corresponds to the function to be controlled from the function table and transmits the function identifier together with information including the set value for the function to the home electrical appliance which corresponds to the function identifier retrieved by making reference to the built-in function information.

5. The home electrical appliance control device according to claim 1, wherein the attributes are at least one of:

a function name, which is the name of the function which corresponds to the function identifier;

a function description, which is a description of the function which corresponds to the function identifier;

the data type of a control description that indicates the operating state of the function which corresponds to the function identifier;

a size, which is the data length of the control description of the function which corresponds to the function identifier;

a value range, which is a numerical value range permitting setting of the control description of the function which corresponds to the function identifier; and

access information indicating controllability with respect to the function which corresponds to the function identifier.

6. A control method for a control device for controlling a home electrical appliance connected via a communication line,

wherein the control device performs the steps comprising:

holding a function table, which includes function identifiers that permit the control device and the home electrical appliance to commonly identify the types of functions with which the home electrical appliance is equipped, and attribute information for the functions; and

built-in function information tables, which include built-in function information that indicates the functions built into each home electrical appliance and identification information that identifies the home electrical appliance;

specifying the function identifier of a certain function which is the control target from the function table; and

specifying home electrical appliance identification information that includes the specified function identifier, from the built-in function information tables.

7. The control method according to claim 6, further comprising the step of inquiring a state of a function of a home electrical appliance constituting the control target on the basis of the specified function identifier and identification information.

8. The control method according to claim 6, further comprising the step of transmitting the specified function identifier and setting information which is to be set for the function to the home electrical appliance which corresponds to the identification information to control the functions of the home electrical appliance.

9. The control method according to claim 8, further comprising the steps of:

broadcasting the identification information is broadcast to all of the home electrical appliances connected to the communication line; and

updating the setting for the function identifier of the home electrical appliance to the received setting information when the home electrical appliance comprises a function which corresponds to the function identifier thus received.

10. A control program for a control device for controlling a home electrical appliance connected via a communication line, wherein the control program causes the control device to perform the steps of:

holding a function table, which includes function identifiers that permit the control device and the home electrical appliance to commonly identify the types of functions with which the home electrical appliance is equipped, and attribute information for the functions; and

built-in function information tables, which include built-in function information that indicates the functions built into each home electrical appliance and identification information that identifies the home electrical appliance;

specifying the function identifier of a certain function which is the control target from the function table; and

specifying home electrical appliance identification information that includes the specified function identifier, from the built-in function information tables.

11. A home electrical appliance that is connected via a communication line to a control device, comprising:

a memory section for storing a built-in function table which is constituted by selecting a combination of function identifier and attributes in accordance with the functions of the home electrical appliance from a function table for mapping function identifiers that permit the control device and the home electrical appliance to commonly identify the function types allocated, based solely on the functions, to functions of the home electrical appliance regardless of kinds of the home electrical appliances, with attributes of the functions; and

a transmission section for transmitting a built-in function notice that includes a function identifier on the basis of the built-in function table, and access information that indicates the ability of the control device to control the function which corresponds to the function identifier, to the control device via the communication line.
