Sensor detection threshold determination method, device, storage medium, and processor

Abstract

The invention discloses a sensor detection threshold determination method, device, a storage medium, and a processor. The method comprises steps: the background noise of a target device is collected;the collected background noise is analyzed to obtain a first curve and a second curve, wherein the first curve is used to represent the change of the intensity of the background noise during an observation period, and the second curve is used to represent the change of the time-frequency parameters of the background noise during the observation period; and based on the first curve and the second curve, the noise threshold of the target sensor and the filter bandwidth of the target sensor are determined, wherein the target sensor is used to collect the discharge signal of the target device to detect the target device. Thus, the problems that when a related technology is applied to partial discharge of high-voltage equipment, setting of the detection threshold of the sensor is performed manually or through experience, threshold setting is generally completed at one time after the sensor is mounted, and adaptability to the field environment is lacked can be solved.

Description

technical field [0001] The present application relates to the field of electric equipment detection, in particular, to a method and device for determining a detection threshold of a sensor, a storage medium, and a processor.
