Sensor distance regulation method and device

Abstract

The present invention relates to a sensor distance regulation method, belonging to the technical field of location. The method comprises the steps of: obtaining an azimuth angle and an angle of pitchof a device to be detected relative to a sensor array to determine the estimation position of the device to be detected; rotating the sensor array to allow the sensor array to face the estimation position of the device to be detected; obtaining time of each sensor receiving partial discharge signals in the sensor array to obtain the time difference value between each two sensors; and inputting thetime difference values into a pre-built error distance calculation module, and taking a preset distance error range as a constraint condition to determine a value range of a first distance and regulate the distance between each two sensors according to the value range. The sensor distance regulation method and device solve the problem that direction-finding errors cannot be eliminated when a static sensor measures the direction of the partial discharge signals, and can regulate the distance of the sensor according to the direction measurement error range so as to achieve accurate orienteering.

Description

technical field [0001] The invention relates to the field of positioning technology, in particular to a sensor distance adjustment method, device, readable storage medium and storage device. Background technique [0002] In the power industry, the Ultra High Frequency (UHF) signal method is often used to carry out short-distance orientation of power equipment, that is, a number of UHF sensors are arranged near the equipment to be inspected, and the UHF signals generated by the partial discharge of the equipment to be inspected are used to reach different UHF sensors. The situation to determine the direction of the device to be tested. During the process of realizing the present invention, the inventors have found at least the following problems in the prior art: the azimuth measurement method is mainly applied to long-distance direction finding. If the azimuth angle measurement method is combined with the UHF signal method and applied to short-distance orientation, there ma...
