Abstract

According to the present invention, a method for controlling a load comprises the steps of: receiving, from a host device, a load control message for controlling at least one or more load devices; transmitting a load control command to the at least one or more load devices, on the basis of at least one of said load control message, state information of the load devices and, a preset load control condition; and transmitting, to said host device or an external device, a response message that includes information indicative of a load control state in response to said load control message.

Claims

1. A load control method, the method comprising:

a) receiving, from a host device, a load control message for controlling at least one load device;

b) transmitting a load control command to the at least one load device, based on at least one of the load control message, state information of the load device and a preset load control condition; and

c) transmitting a response message comprising information indicating load control state to the host device or an outside device in response to the load control message, wherein the state information of the load device includes any one of contact state, non-contact state and keep state.

2. The load control method of claim 1, wherein the load control message comprises identity information identifying at least one load device, and control information controlling a load of the load device corresponding to the identity information, wherein the load control command is the load control message or includes the load control message.

3. The load control method of claim 1, wherein the load control message comprises at least one of an ON-time section of the load device, OFF-time section, and information controlling an operation subsequent to a predetermined time after receipt of message.

4. The load control method of claim 1, wherein the load control command includes a command controlling an activation switch of the load device.

5. The load control method of claim 1, wherein the c) step includes transmitting the response message including information indicating the load control state in response to a request from the hose device or the outside device.

6. The load control method of claim 1, wherein the preset load control condition is to activate the at least one load device when price information does not surpass a particular value.

7. The load control method of claim 1, wherein the preset load control condition is to activate the at least one load device in association with an electricity rate.

8. The load control method of claim 1, wherein the preset load control condition is to activate the load of the load device in adaptive response to amount of consumed electricity.

9. The load control method of claim 1, wherein the keep state of the load device is to keep the contact state when previous state information is in a contact state and to keep the non-contact state when the previous state information is in a non-contact state.

10. A load control method, the method comprising:

a) from a host device, a load control message for controlling at least one load device;

b) generating a load control command for load control of the load device, based on at least one of the load control message, state information of the load device and a preset load control condition; and

c) performing load control of the load device in response to the load control command, wherein the load control message comprises identity information identifying the load device and control information controlling a load of the load device corresponding to the identity information.

11. The load control method of claim 10, wherein the load control message comprises at least one of an ON-time section of the load device, OFF-time section, and information controlling an operation subsequent to a predetermined time after receipt of message.

12. The load control method of claim 10, further comprising:

d) transmitting a response message comprising information indicating load control state of the load device in response to request of the host device.

13. The load control method of claim 10, wherein the preset load control condition is to activate the at least one load device when price information does not surpass a particular value.

14. The load control method of claim 10, wherein the preset load control condition is to activate the at least one load device in association with an electricity rate.

15. The load control method of claim 10, wherein the preset load control condition is to activate the load of the load device in adaptive response to amount of consumed electricity.

16. The load control method of claim 10, wherein the load control includes a power control of the load device.

17. The load control method of claim 16, wherein the power control of the load device is performed by controlling an output terminal disposed inside a device receiving the load control message.

18. The load control method of claim 16, wherein the power control of the load device is performed by transmitting the load control command to a power control outside device configured to control a power of the load.

19. The load control method of claim 16, wherein the power control of the load device is such that a power-OFF is realized by a remote communication and a power-ON is realized by a remote communication or manually on the spot.

20. The load control method of claim 16, wherein the load control is to control electricity (amount) consumed by the load device based on any one of a real-time power consumption used by the load device, a time-varying power and price information.
