COLLECTION METHOD in the storage devices other than the central station, data from multiple devices, seismic data acquisition

摘要

It is proposed a method for collecting, in a collecting device distinct from a central unit, data coming from a plurality of seismic acquisition units. The method comprises a step of assigning at least one device as a sink unit. For a given sink unit, the method also comprises the following steps for data specific to at least one seismic acquisition unit not assigned as a sink unit: transmitting the specific data from the at least one seismic acquisition unit to the given sink unit, via a radio path established in a radio multi-hop network built at least with the given sink unit and the plurality of seismic acquisition units; and transmitting the specific data from the given sink unit to the collecting device, via a link.
