Abstract

A relay and a data processing method are provided. The relay includes: a detection unit for classifying and detecting event oriented monitoring data and non-event oriented monitoring data from monitoring data; a storage unit for storing the detected monitoring data; a communication unit for receiving a request signal of the monitoring data from a monitoring device and transmitting corresponding monitoring data in response to a transmission request signal of the monitoring data; and a control unit for extracting event oriented monitoring data from the monitoring data and performing a control to transmit the monitoring data requested from the monitoring device.

Claims

1. A relay comprising:

a detection unit for classifying and detecting event oriented monitoring data and non-event oriented monitoring data from monitoring data;

a storage unit for storing the detected monitoring data;

a communication unit for receiving a request signal of the monitoring data from a monitoring device and transmitting corresponding monitoring data in response to a transmission request signal of the monitoring data; and

a control unit for extracting event oriented monitoring data from the monitoring data and performing a control to transmit the monitoring data requested from the monitoring device.

2. The relay according to claim 1, wherein the detection unit detects event oriented monitoring data first when detecting monitoring data.

3. The relay according to claim 1, wherein the control unit checks a type of the monitoring data requested from the monitoring device, and performs a control to extract data corresponding to the type of the checked monitoring data from the storage unit in order to transmit the extracted data.

4. The relay according to claim 1, wherein the control unit stores the detected setting value data and the detected monitoring data in a corresponding point in a point list defined by Distributed Network Protocol (DNP).

5. The relay according to claim 1, wherein, when the detection unit detects event oriented monitoring data, the event oriented monitoring data are stored in a point corresponding to the detected event oriented monitoring data.

6. The relay according to claim 1, wherein the transmission request signal of the monitoring data comprises at least one of event oriented monitoring data or monitoring data of a specific index, and the control unit checks the transmission request signal, and transmits corresponding monitoring data to the monitoring device.

7. A monitoring data processing method of a relay, the method comprising:

detecting user setting value data;

storing the detected setting value data;

checking a communication state with respect to a monitoring device that requests the monitoring data;

detecting event oriented monitoring data from the monitoring data;

storing the detected monitoring data;

receiving a transmission request signal of monitoring data from the monitoring device; and

transmitting the monitoring data in response to the transmission request signal of the monitoring data.

8. The method according to claim 7, further comprising storing the detected setting value data and the detected monitoring data in a corresponding point in a point list defined by DSP.

9. The method according to claim 7, wherein the detecting of the monitoring data comprises detecting at least one of event oriented monitoring data and non-event monitoring data.

10. The method according to claim 9, when the event oriented monitoring data are detected, further comprising storing the event oriented monitoring data in a point corresponding to the detected event oriented monitoring data.

11. The method according to claim 9, further comprising transmitting monitoring data in response to the transmission request signal, wherein the transmission request signal of the monitoring data comprises at least one of event oriented monitoring data and monitoring data of a specific index.
