SYSTEM AND METHOD FOR LOCATING UNDERGROUND LINES USING ANTENNA AND POSITIONING INFORMATION

摘要

A system and method of for underground line location includes an underground line locator. The underground line locator includes an antenna system configured to generate signal information based on a proximity and an orientation of an underground line relative to the antenna system, a positioning system configured to generate position information based on the location of the underground line locator, and a controller coupled to the antenna system and the positioning system. The controller is configured to receive the signal information from the antenna system and the positioning information from the positioning system.

主权项

1. An underground line locator comprising:
a first antenna disposed at a first position, the first antenna determining first signal information associated with an alternating current (AC) magnetic field associated with an underground line; and a second antenna disposed at a second position apart from the first position, the second antenna determining second signal information associated with the AC magnetic field; wherein:
the first signal information includes a first magnitude and a first angle; andthe second signal information includes a second magnitude determined along an axis defined by the first angle.
