MULTIPLEXING SIGNATURE ALLOCATION FOR WIRELESS EXPLORATION SYSTEM

摘要

Systems and methods related to allocation of multiplexing signatures to wireless data acquisition modules in a seismic array with real time wireless read out. The allocation may include selecting an index value offset from an adjacent index value to form serial data transfer paths wherein reuse of multiplexing signatures are spaced as far apart as possible in serial data path. In an embodiment the allocation of multiplexing signatures may be adaptive wherein a module may scan for the presence of signals utilizing a plurality of multiplexing signatures and in turn employ a multiplexing sequence that avoids any detected noise that could lead to interference. The detected noise may be attributable to sources within the survey area or from ambient noise present in the area.

1. A method for adaptive allocation of multiplexing signatures to a wireless module in a seismic data acquisition system, the method comprising:
first scanning with a first wireless module in the seismic data acquisition system for use of each of a plurality of predetermined multiplexing signatures during a plurality of transmission time periods; and first selecting at the first wireless module one of the plurality of predetermined multiplexing signatures for wireless exchange of seismic data between the first wireless module and another wireless module in the seismic acquisition system for each of the plurality of transmission time periods; wherein the first selecting includes choosing a different one of the plurality of predetermined multiplexing signatures for use during each of the transmission time periods based on the first scanning to develop a first multiplexing sequence for the first wireless module.
