First Claim
Patent Images
1. A seismic system for geophysical exploration comprising:
- at least one remote geophone monitoring means, each said remote geophone monitoring means being adapted to receive electrical signals from at least one geophone means; and
a central control means for generating electrical signals for initiating the operation of said at least one remote geophone monitoring means;
said central control means including means for receiving data from said at least one remote geophone monitoring means;
each said remote geophone monitoring means including;
means for generating a tilt alarm signal representative of an indication that said remote geophone monitoring means has been tilted with respect to a desired position of said remote geophone monitoring means;
means for sensing that said remote geophone monitoring means has been tilted with respect to a desired position of said remote geophone monitoring means and for generating an enabling signal when said remote geophone monitoring means has been tilted;
means for supplying said enabling signal to said means for generating a tilt alarm signal to thereby enable said means for generating a tilt alarm signal to generate a tilt alarm signal;
means for transmitting a signal to said central control means;
means for supplying said tilt alarm signal to said means for transmitting a signal to said central control means, said tilt alarm signal being automatically supplied from said remote geophone monitoring means to said central control means.

Abstract
In a seismic exploration in which a plurality of remote geophone monitors are utilized to acquire data from a plurality of geophones and transmit the data to a central control station, method and apparatus is provided whereby an indication that the remote geophone monitor has been tilted is transmitted from the remote geophone monitor to the central control station. Method and apparatus can also be provided whereby an audio alarm is sounded at the location of the remote geophone monitor if the remote geophone monitor is tilted.

5. A method for indicating that a remote geophone monitoring means has been tilted with respect to a desired position of said remote geophone monitoring means comprising the steps of:
-
sensing that said remote geophone monitoring means has been tilted with respect to a desired position of said remote geophone monitoring means and generating an enabling signal when said remote geophone monitoring means is tilted; generating a tilt alarm signal in response to said enabling signal; and automatically transmitting said tilt alarm signal from said remote geophone monitoring means to a central control station to thereby provide an indication that said remote geophone monitoring means has been tilted. - View Dependent Claims (6, 7, 8)
