Abstract
Official abstract text for this publication.
A digital seismic sensor adapted to be connected, via a two-conductor line, to an acquisition device. The digital seismic sensor includes: a digital sensor; a local sampling clock providing a sampling frequency; a receiver for receiving command data coming from the acquisition device and synchronization information providing accurate timing information to enable seismic sensor synchronization; a compensator for compensating, as a function of the synchronization information, a drift of the local sampling clock; a transmitter for transmitting seismic data towards the acquisition device; a driver for driving the receiver and the transmitter, according to a half-duplex transmission protocol over the two-conductor line and using a transmission clock extracted from the received command data; a power receiver for receiving electrical power; and a coupler for coupling the command and synchronization information receiver, the transmitter and the power receiver to the two-conductor line.
First claim
Opening claim text (preview).
The invention claimed is: 1. A seismic sensor adapted to be connected, via a two-conductor line, to an acquisition device which acquires seismic data provided by the seismic sensor and transmits said seismic data to a central recording system or to an intermediate collection device, wherein said seismic sensor is a digital seismic sensor comprising: a digital sensor providing said seismic data; a local sampling clock providing a sampling frequency to said digital sensor; a dat…
