Apparatus and method for collecting geophysical information

摘要

An apparatus for collecting geophysical information may include a geophysical information station disposed along a seismic communication cable. A bypass circuit responsive to a command signal is in communication with a switching circuit that is operable to route electrical power, commands, data or a combination to bypass the geophysical information station in response to the command signal. An exemplary method for bypassing a geophysical information station in a geophysical information collection system includes sending a command signal to a bypass circuit and activating one or more switching circuits using the bypass circuit to route electrical power, commands, data or a combination to bypass the geophysical information station in response to the command signal.

1. An apparatus for collecting geophysical information comprising:
a first geophysical information station disposed along a seismic communication cable, said first geophysical information station including:
a command circuit for receiving command signals from an upstream source and transmitting commands to a downstream source;a first bypass circuit responsive to a command signal issued by the command circuit to issue a first bypass signal; anda switching circuit in communication with a first bypass circuit of a first upstream geophysical information station to receive a bypass signal and operable to route electrical power, commands, and data to bypass said first geophysical information station in response to a command signal from a command circuit of the first upstream geophysical information station causing the generation of a first bypass signal by the first upstream geophysical information station.
