Seismic Data Acquisition Systems and Methods for Managing Messages Generated by Field Units
First Claim
1. A system for acquiring seismic data, comprising:
- a source for generating acoustic signals into a subsurface of the earth;
a plurality of receivers placed in a selected region for detecting signals reflected from the subsurface and responsive to the generated acoustic signals; and
a plurality of field station units (FSUs), wherein each FSU in the plurality of FSUs;
(i) receives acoustic signals detected by at least one receiver associated therewith in the plurality of receivers;
(ii) detects a condition for each of a plurality of attributes relating to acquisition of the seismic data; and
(iii) transmits wirelessly a plurality of messages to a remote unit indicative of the condition for each attribute when such condition meets a selected criterion.

Abstract
A system and method for acquiring seismic data is provided that utilizes a plurality of field station (data acquisition) units placed over a region of interest and a remote central unit. The system and method, in one aspect, determine a condition associated with each of a plurality of preselected attributes relating to the acquisition of the seismic data at each of the field station units, generate messages at each field station when the condition of any particular attribute meets a selected criterion, and transmit the generated messages to a remote unit wirelessly. The system and methods provide efficient use of the available bandwidth and avoid collisions among messages transmitted simultaneously by several field station units. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
