Abstract

The network configuration technology for controlling an electric power sensor node is disclosed. The method for controlling electric power includes transmitting an an Ethernet packet type command message to at least one electric power sensor node through an LRWPAN-Ethernet bridge in accordance with profile information related to an electric power control, the profile information being set by a user; receiving LR-WPAN packet type response messages transmitted from the at least one electric power sensor node in response to the Ethernet package type command message as Ethernet packet type response messages through the LRWPAN-Ethernet bridge; and providing a control result of an electric power equipment corresponding to the at least one electric power sensor node to the user based on the Ethernet packet type response messages.

Claims

1. A method for controlling electric power in an electric power controller, comprising:

transmitting an Ethernet packet type command message to at least one electric power sensor node through an LRWPAN-Ethernet bridge in accordance with profile information related to an electric power control, the profile information being set by a user;

receiving LR-WPAN packet type response messages transmitted from the at least one electric power sensor node in response to the Ethernet package type command message as Ethernet packet type response messages through the LRWPAN-Ethernet bridge; and

providing a control result of an electric power equipment to the user based on the Ethernet packet type response messages.

2. The method of claim 1, wherein the at least one electric power sensor node is connected with the electric power equipment and the Ethernet packet type command message includes information for controlling the electric power equipment.

3. The method of claim 1, wherein the electric power controller is connected with a plurality of LRWPAN-Ethernet bridges through a wire communication network and the Ethernet packet type command message includes an MAC address for identifying the plurality of LRWPAN-Ethernet bridges.

4. The method of claim 3, further comprising retrieving the MAC address for identifying the electric power controller among the Ethernet packet type response messages,

wherein the receiving the LR-WPAN packet type response messages receives an Ethernet packet type response message including the MAD address for identifying the electric power controller.

5. The method of claim 4, further comprising retrieving identification information of the at least one electric power sensor node,

wherein the receiving the LR-WPAN packet type response messages filters the Ethernet packet type response message duplicately received based on the identification information of the at least one electric power sensor node.

6. The method of claim 2, wherein the Ethernet packet type command message includes a state information request message for the at least one electric power sensor node and the providing the control result provides a state information of the electric power equipment to the user based on the Ethernet packet type response messages.

7. The method of claim 2, wherein the Ethernet packet type command message includes a command message for turning on/off a power supply of the electric power equipment and the providing the control result provides an on/off state of the power supply of the electric power equipment based on the Ethernet packet type response messages to the user.

8. The method of claim 7, wherein the transmitting the Ethernet packet type command message transmits the command message to an electric power sensor node connected with the electric power equipment to be turned on/off among the at least one electric power sensor node.

9. A method for controlling electric power in an LRWPAN-Ethernet bridge, comprising:

receiving an Ethernet packet type command message to be transmitted to at least one electric power sensor node from an electric power controller;

converting the Ethernet packet type command message into an LR-WPAN packet type command message through header conversion;

transmitting the LR-WPAN packet type command message to the at least one electric power sensor node; and

reconverting LR-WPAN packet type response messages transmitted from the at least one electric power sensor node in response to the Ethernet packet type command message into Ethernet packet type response messages and retransmitting the reconverted Ethernet packet type response messages to the electric power controller.

10. The method of claim 9, wherein the LRWPAN-Ethernet bridge is connected with the at least one electric power sensor node through a wireless communication network, and

the transmitting the LR-WPAN packet type command message transmits the LR-WPAN packet type command message to each of the electric power sensor nodes through the wireless communication network.

11. The method of claim 10, wherein the at least one electric power sensor node is connected with an electric power equipment and the Ethernet packet type command message includes information for controlling the electric power equipment.

12. The method of claim 9, wherein the Ethernet packet type command message includes an MAC address for identifying the LRWPAN-Ethernet bridge, and

the receiving the Ethernet packet type command message receives the Ethernet packet type command message including the MAC address for identifying the LRWPAN-Ethernet bridge.

13. The method of claim 9, wherein the converting the Ethernet packet type command message removes an Ethernet header from the Ethernet packet type command message.

14. The method of claim 9, wherein the reconverting the LR-WPAN packet type response messages adds an Ethernet header to the LR-WPAN packet type response message.

15. The method of claim 9, wherein the LR-WPAN packet type response message including an MAC address for identifying the electric power controller among the Ethernet packet type response messages is identified, and

the retransmitting the LR-WPAN packet type command message transmits the Ethernet packet type response message to the corresponding electric power controller based on the MAC address.
