ON-LINE STATUS DIAGNOSIS DEVICE AND ON-LINE STATUS DIAGNOSIS METHOD FOR ELECTRIC POWER UTILITIES
First Claim
1. An on-line status diagnosis device for an electric power utilities, which comprises a degradation detection sensor configured to provide a degradation detection signal as an electrical analog signal by detecting a degradation status of the electric power utilities, a data acquisition unit (DAU) configured to acquire and provide degradation detection data based on the degradation detection signal, and a communication unit configured to transmit the degradation detection data from the DAU to the outside of the on-line status diagnosis device,wherein the DAU comprises:
- an analog-digital converter configured to acquire degradation detection data as digital data by converting the degradation detection signal from the degradation detection sensor into a digital signal; and
a microcomputer configured to determine a degree of risk by comparing the degradation detection data with at least one predetermined risk determination reference value, if the degree of risk is high, output a control signal to the analog-digital converter to increase a sampling rate that is a number of sampling times of detection data per unit time in the analog-digital converter and also output the degradation detection data to quicken a report rate that is a time required to transmit data of a predetermined number, and if the degree of risk is low, output a control signal to the analog-digital converter to decrease the sampling rate of the analog-digital converter and also output the degradation detection data to decrease the report rate.

Abstract
The present invention is to provide an on-line status diagnosis device for an electric power utilities, in which sampling and data transmission rates are differentiated according to a degree of risk of degradation status data. The on-line status diagnosis device includes a sensor for providing a degradation detection signal of the electric power utilities, a data acquisition unit (DAU) for acquiring and providing degradation detection data, and a communication unit for transmitting the degradation detection data to the outside. The DAU includes an analog-digital converter for acquiring degradation detection data as digital data by converting the degradation detection signal from the sensor into a digital signal, and a microcomputer for determining a degree of risk by comparing the degradation detection data with at least one predetermined risk determination reference value, and outputting a control signal to the analog-digital converter to change a sampling rate and a report rate.
