US 5,351,218 A · Method for reconnection and connection of sensor groups

Abstract

A method for reconnection and connection of sensor groups, especially hydrophone groups or channels in a seismic cable, where the active sections in the seismic cable are connected with electronic modules or one another via connector plugs, is based on the principle that a specific number of hydrophone groups are connected symmetrically on each side of each electronic module. The number of connected hydrophone groups on each side is identical and constitutes at least one respective active section. A summation of a set of hydrophone groups in a section is performed automatically by connecting this section with another section or by connecting a respective section and the electronic module.

A method for reconnection and connection of hydrophone sensor groups i a seismic streamer having a plurality of active sections connected with electronic modules via connector plugs, comprising:

connecting together a specific number of hydrophone groups on each side of each electronic module to form a first active section on one side of said electronic module and a second active section on the other side of said electronic module, each active section comprising a forward section and a rearward section, said forward section of said first active section being symmetrical with said rearward section of said second active section, so that the number of hydrophone groups in said forward section and said rearward section on each side of each electronic module is identical;
and
automatically performing a summation of a set of hydrophone groups in at least one respective first and second active section by connecting said at least one respective active section with another respective active section.
