Abstract

The present invention discloses a home network system (1) which can provide an efficient address system for home appliances by using a dynamic address field selectively including at least two different kinds of logical address codes. The home network system (1) includes at least one slave device (40), and a master device (30) connected to the slave devices (40) through a predetermined network (20), the master device (30) and the slave device (40) distinguishing each other by an address field including a dynamic address field selectively having at least two different kinds of logical address codes to distinguish a plurality of slave devices (40) and master devices (30).

Claims

1. A home network system, comprising:

at least one slave device; and

a master device connected to the slave devices through a predetermined network, the master device and the slave device distinguishing each other and communicating with each other by an address field including a dynamic address field selectively having at least two different kinds of logical address codes to distinguish a plurality of slave devices and master devices.

2. The home network system of claim 1, wherein the address field further comprises a fixed address field having a product code provided for the slave device and the master device.

3. The home network system of claim 2, wherein the fixed address field further comprises a network code field.

4. The home network system of either claim 2 or 3, wherein the fixed address field is stored in a nonvolatile memory before the master device and the slave device are connected to the home network system.

5. The home network system of claim 1, wherein the logical address code is a device code for distinguishing a plurality of slave devices and master devices of the same kind in the home network system.

6. The home network system of claim 5, wherein the device code is set by the master device.

7. The home network system of claim 1, wherein the logical address code is a cluster code for clustering the slave device and the master device according to a predetermined standard.

8. The home network system of claim 7, wherein the standard is an installation area of each device.

9. The home network system of claim 7, wherein the standard is a user of the devices.

10. The home network system of either claim 5 or 7, wherein the address field further comprises a flag for indicating whether the logical address code of the dynamic address field is a device code or cluster code.

11. The home network system of either claim 5 or 7, wherein the master device a nd the s lave device store the device code and the cluster code i n the nonvolatile memory.

12. A storage medium for storing an address field of a home network system, the address field used in the home network system comprised of at least two home appliances comprising a fixed address field having a product code provided for the home appliances, and a dynamic address field selectively having at least two different kinds of logical address codes for distinguishing the home appliances.

13. The storage medium of claim 12, wherein the fixed address field further comprises a network code field.

14. The storage medium of claim 12, wherein the code included in the logical address field is a device code for distinguishing a plurality of home appliances of the same kind.

15. The storage medium of claim 12, wherein the code included in the logical address field is a cluster code for clustering the slave device and the master device according to a predetermined standard.

16. The storage medium of claim 15, wherein the standard is an installation area of each device.

17. The storage medium of claim 15, wherein the standard is a user of the devices.

18. The storage medium of either claim 14 or 15, wherein the address field further comprises a flag for indicating whether the logical address code of the dynamic address field is a device code or cluster code.
