TECHNIQUES FOR SURFACE EXPLORATION AND MONITORING

摘要

Techniques for surface exploration and monitoring are presented. In representative embodiments, a controller can be configured to automatically poll survey probes to obtain identifiers of the probes and determine a relative order the probes. In some embodiments, survey probes can be configured to: (a) collect signals associated with a surface; (b) digitize the signals to form digital data; and (c) store the digital data for later transmission to the survey controller. In some embodiments, survey probes can be configured to: (a) inject current into the surface or (b) provide a return path therefor. Relative positions of survey probes, including those configured to introduce current into a surface as stimulus for geophysical measurements can be automatically determined. Sensor-type survey probes can automatically disconnect from a power conduit while measuring a surface property and operate using an internal source of power when disconnected, to reduce noise.
