Abstract
An underground digital locating system includes a receiver capable of acquiring a signal produced by an underground object and displaying a digital representation of the orientation of underground object and of its depth. The system includes a carrying case for the digital locating receiver, the carrying case further including a transmitter for energizing underground objects to emit a magnetic field. A method of locating an underground object using the described system is also disclosed, as well as methods of measuring a flux field and translating a flux field signal of an underground object into a visual representation of the underground object on the display screen of the locating receiver.
Claims8
A method of measuring a flux field signal emitted by an underground object by using a locating receiver comprising the steps of:
- acquiring said flux field signal by a locator having a first set of antennas and a second set of antennas, the antennas of each set emitting a response upon acquiring said signal;
- processing said response from each antenna through a network of analog switching circuitry housed within said receiver, said switching circuitry being controlled by a microcontroller;
- said antenna responses being passed by said circuitry through a sum and a difference amplifier, producing numerical results;
- and
- whereby said flux field is calculated by mathematical processing of said numerical results, said mathematical processing calculating magnitude and phase of said antenna responses.
