Abstract

Provided is a method of controlling a network system. In the method, it is determined whether a communication modem of an electric product is operable by transmitting a signal between the communication modem and a component. If the communication modem is operable for communication with the component, an operation of the electric product is controlled based on power information received through the communication modem.

Claims

1. A method of controlling an electric product, the method comprising:

determining whether a communication device is operable by transmitting a signal between the communication device and a component; and

if the communication device is operable for communication with the component, controlling an operation of the electric product based on power information received through the communication device.

2. The method according to claim 1, wherein the component is one of an energy management system (EMS) to check a state of the electric product or control the operation of the electric product, a metering device to measure a power consumption amount of the electric product, and the electric product.

3. The method according to claim 1, wherein the determining comprises:

transmitting a check signal to the communication device by the component; and

determining whether a response signal is received from the communication device by the component.

4. The method according to claim 3, wherein if the component receives the response signal from the communication device, the method further comprises communicating with the communication device by the component.

5. The method according to claim 3, wherein if the component does not receive the response signal from the communication device, the method further comprises:

determining whether the check signal is sent more than a predetermined number of times; and

if it is determined that the check signal is sent more than the predetermined number of times times, determining that the communication device is not operable for communication.

6. The method according to claim 5, wherein if the communication device is not operable for communication, the method further comprises displaying the non-operable state information on the component.

7. The method according to claim 1, wherein the communication device sending an operation instruction to the electric product based on the power information by the communication device.

8. The method according to claim 1, further comprises operating the electric product in a mode for reducing a power consumption amount or an electricity charge based on the power information.

9. The method according to claim 1, further comprises operating the electric product in a mode not to exceed an upper limit of electricity charge based on the power information.

10. An electric product for a network system comprising:

a communication device in which power information is communicated; and

a controller that controls an operation of the electric product based on the power information received through the communication device when the communication device is operable; and

a display to display information.

11. The electric product according to claim 10, wherein the display displays at least one of power information of a power source, an operation information of the electric product, power information related to the electric product, and a communication state of the electric product.

12. The electric product according to claim 10, wherein the communication device is detachably attached to the electric product.

13. The electric product according to claim 10, wherein the network system further comprises:

a component that determines whether communication is operable by transmitting a signal between the component and the communication device.

14. The electric product according to claim 13, wherein if the component receives a response signal from the communication device, the component determines that the communication device is operable.

15. The electric product according to claim 14, wherein if the component does not receive the response signal from the communication device, the component determines whether the check signal is sent more than a predetermined number of times;

and

if it is determined that the check signal is sent more than the predetermined number of times, the component determines that the communication device is not operable for communication.

16. The electric product according to claim 13, wherein if the communication device is not operable for communication, the component displays the non-operable state information.

17. The electric product according to claim 13, wherein the component is one of an energy management system (EMS) to check a state of the electric product or control the operation of the electric product, a metering device to measure a power consumption amount of the electric product, and the electric product.

18. The electric product according to claim 10, wherein the communication device sends an operation instruction to the electric product based on the power information.

19. The electric product according to claim 18, wherein the electric product operates in a mode for reducing a power consumption amount or an electricity charge based on the power information.

20. The electric product according to claim 18, wherein the electric product operates in a mode not to exceed an upper limit of electricity charge based on the power information.
