Pipeline locator receiver coil structure, signal processing method, pipeline locator receiver

Abstract

The invention belongs to the technical field of power cables, and discloses a pipeline locator receiver coil structure, a signal processing method, and a pipeline locator receiver. The pipeline locator receiver is characterized in that the pipeline locator receiver acquires magnetic field signals of buried cables through a coil and can calculate the location information of the cables by combiningwith methods of analog signal conditioning and digital signal processing; a first horizontal coil detects the magnetic field signals of the buried cables in the horizontal direction, and is combined with a second horizontal coil to measure the buried depth of the buried cables and the magnitude of the current of the buried cables; a vertical coil detects the magnetic field signals of the buried cables in the vertical direction, and is combined with the first horizontal coil to detect the left and right locations of the buried cables; and a third horizontal coil is combined with the second horizontal coil to measure the included angle between the receiver and the buried cables to realize the compass function. The pipeline locator receiver has the advantages of high reliability, compact andreasonable coil structure, complete detection functions, low cost, high anti-interference capability, relatively higher detection accuracy and relatively higher sensitivity.

Description

technical field [0001] The invention belongs to the technical field of power cables, and in particular relates to a coil structure of a pipeline instrument receiver, a signal processing method, and a pipeline instrument receiver. Background technique [0002] In recent years, with the rapid development of domestic power grids, buried cables have been widely used in order to reduce the space resources occupied by overhead lines. Considering that the transformation of the power grid and the relocation of cables may make the original drawings and materials unable to correctly reflect the laying path of underground cables, if the location information of underground cables is not clear enough, it is very difficult to find them, which not only wastes a lot of manpower, material resources and time, but also Incalculable losses will be caused. Domestic research on buried cable path detection started relatively late, but it has developed rapidly. At present, there are many scientifi...
