Abstract

A method for recognizing an electronic appliance in multiple control system for controlling at least one electronic appliance is disclosed, which includes the steps for setting each ID including a variable value and a fixed value to the electronic appliances, determining whether the electronic appliances of the same model exist among the connected electronic appliances on connecting the electronic appliances to the multiple control system by reading corresponding ID and analyzing the ID value; changing the ID of the connected electronic appliance in case that the electronic appliances of the same model exist; and recognizing the corresponding electronic appliance as the changed ID.

Claims

1. A method for recognizing an electronic appliance in a multiple control system capable of controlling more than one electronic appliance, comprising:

setting up an ID which includes a variable value and a static value for each electronic appliance;

transmitting the ID from an electronic appliance to a central controller;

reading the ID when connecting the electronic appliance to a network, analyzing the ID, and deciding whether another electronic appliance, connected to the network, having the same ID exists among any other electronic appliances connected to the network; and

changing the variable value of the ID of the electronic appliance connected to the network at the central controller, if it is decided that another electronic appliance has the same ID, and recognizing the corresponding electronic appliance with the newly changed ID, wherein the static value is based on a model number of the electronic appliance.

2. The method of claim 1, wherein analyzing the ID is carried out by comparing the static value with a pre-determined static value.

3. The method of claim 1, further comprising:

transmitting an ID change command to each electronic appliance, when changing the ID of the connected electronic appliance; and

changing only the variable value of the ID data corresponding to the electronic appliance in which an ID change is carried out.

4. The method of claim 1, wherein changing the variable value involves incrementing the variable value.

5. The method of claim 1, wherein the electronic appliance having its ID changed sets an ID change flag.

6. A method for recognizing an electronic appliance in a multiple control system controlling more than one electronic appliance, comprising:

setting up an ID for each electronic appliance according to its model number;

reading the ID when connecting the electronic appliance to the network, analyzing the ID value, recognizing whether other electronic appliances connected to the network have the same ID, and recognizing data of a corresponding appliance model by matching a given virtual ID, wherein the virtual ID is deleted when the power of its corresponding electronic appliance is turned off.

7. The method of claim 6, wherein the electronic appliance given a virtual ID sets an ID change flag.
