Abstract

A network system including a first electric appliance having a memory unit and a second electric appliance to communicate with the first electric appliance, in which the second electric appliance includes a first memory unit storing software for monitoring an operation of the second electric appliance and a second memory unit storing software for managing operation information of the first electric appliance delivered from the first electric appliance.

Claims

1. A network system comprising:

a first electric appliance having a memory unit; and

a second electric appliance to communicate with the first electric appliance,

wherein the second electric appliance comprises;

a first memory unit storing software for monitoring an operation of the second electric appliance; and

a second memory unit storing software for managing operation information of the first electric appliance delivered from the first electric appliance.

2. The network system of claim 1, wherein, when the first electric appliance and the second electric appliance are communicably connected to each other, the operation information of the first electric appliance is stored in the second memory unit.

3. The network system of claim 1, wherein the memory unit of the first electric appliance comprises:

a first memory region storing software for controlling an operation of the first electric appliance and monitoring a state of the operation;

a second memory region storing software for performing a networking function of accessing the second electric appliance; and

a third memory region storing software for performing a function of delivering the operation information of the first electric appliance to the second electric appliance.

4. The network system of claim 1, wherein the first memory unit comprises:

a first memory region storing software for controlling an operation of the second electric appliance and monitoring a state of the operation;

a second memory region storing software for performing a networking function of accessing the second memory unit; and

a third memory region storing software for performing a function of delivering operation information of the second electric appliance to the second memory unit.

5. The network system of claim 1, wherein the second memory unit comprises a fourth memory region storing software for storing or managing data delivered from the memory unit of the first electric appliance or the first memory unit.

6. The network system of claim 5, wherein the second memory unit further comprises:

a fifth memory region storing software for performing a communication connection with the memory unit of the first electric appliance or the first memory unit; and

a sixth memory region storing software for setting a route for delivering a message between the memory unit of the first electric appliance and the first memory unit.

7. The network system of claim 1, further comprising:

a plurality of second electric appliances, each with a first and a second memory unit, and

wherein the plurality of second electric appliances performs machine-to-machine (M2M) communication.

8. The network system of claim 7, wherein the plurality of second electric appliances form an arrangement of mesh topology in which the plurality of second electric appliances are individually and communicably connected.

9. The network system of claim 7, wherein the second memory unit comprises a seventh memory region storing software for performing a function of processing protocol messages for communication with the plurality of second electric appliances.

10. The network system of claim 1, further comprising:

a mobile device to monitor the operation information of the first electric appliance or transmit a control command for operating the first electric appliance.

11. The network system of claim 10, wherein,

the control command of the mobile device is transmitted to the second electric appliance, and

the second electric appliance transmits a message corresponding to the control command to the first electric appliance.

12. The network system of claim 11, wherein,

the first electric appliance performs an operation corresponding to the message, senses a change in state caused by performing the operation, and transmits an update message for the changed state information to the second electric appliance, and

the second electric appliance transmits, to the mobile device, a response to a result of performing the control command and the update message of the first electric appliance.

13. The network system of claim 10, wherein,

the mobile device requests the operation information of the first electric appliance from the second electric appliance, and

the second electric appliance transmits the operation information of the first electric appliance stored in the second memory unit of the second electric appliance to the mobile terminal as a response.

14. The network system of claim 1, further comprising:

a plurality of first electric appliances, each with a memory unit, and

wherein the plurality of first electric appliances are communicably connected to a communication module of the second electric appliance.

15. The network system of claim 1, wherein the first electric appliance includes an electric kettle, an outlet device, an illustration device, a hair dryer, or a mixer.

16. The network system of claim 1, wherein the second electric appliance includes a washing machine, a refrigerator, an air conditioner, a cooking device, a television, or a robot vacuum cleaner.

17. A control method of a network system, the control method comprising:

communicably connecting a first electric appliance having a memory unit with a second electric appliance having a first memory unit and a second memory unit;

transmitting a message for requesting state information of the first electric appliance or a control command of the first electric appliance from a mobile device while the first and second electric appliances are communicably connected; and

transmitting a state information response message of the first electric appliance or a control result message of the first electric appliance from the second electric appliance to the mobile device.

18. The control method of claim 17, wherein,

the second electric appliance is provided in a plurality, and

the communicably connecting of the first and second electric appliances comprises:

transmitting a communication access request message from the first electric appliance to the plurality of second electric appliances;

transmitting response messages including communication access information from the plurality of second electric appliances; and

communicably connecting the first electric appliance with a second electric appliance that transmits an earliest arriving response message.

19. The control method of claim 17, further comprising:

requesting, by the mobile device, the operation information of the first electric appliance from the second electric appliance; and

transmitting, by the second electric appliance, the operation information of the first electric appliance stored in the second memory unit to the mobile terminal as a response.

20. The control method of claim 17, wherein the first electric appliance is a small home appliance.

21. The control method of claim 17, wherein the plurality of second electric appliances form a machine-to-machine (M2M) communication network.
