DCVG SURVEY SYSTEM, ESPECIALLY MEASURING CONTINUOUS POTENTIAL DISTRIBUTION

摘要

PURPOSE: A DCVG(DC Voltage Gradient) survey system is provided to identify easily a surveying result by detecting a DCVG electrode signal of a buried pipe and displaying the intensity of the DCVG electrode signal. CONSTITUTION: A signal detector(10) is used for detecting a DCVG electrode signal from a probe. A survey unit(20) is used for analyzing the DCVG electrode signal. The survey unit includes a controller(201) for receiving the DCVG electrode signal, an input part(202) for inputting a predetermined command, a storage part(203) for storing the received electrode signal, an analyzer(204) for analyzing the stored electrode signal, and a display(205) for displaying the received electrode signal and the analyzed result. The controller is used for controlling a receiving process, a storing process, an analyzing process, and a displaying process of the DCVG electrode signal according to the predetermined command the input part.
