Method of transmitting to a central apparatus for recording data corresponding to signals received by a set of seismic detectors, and which have been sampled, digitised and stored by a plurality of data- acquisition instruments, and device for implementation. …<??>It comprises the storing of the data in static memories (4) arranged in each of the said instruments, the moving over the terrain in the vicinity of each of them, at the end of each recording session, of a mass memory (10) associated with a device (11) for transferring to this mass memory data collected by a high-throughput link (cable, wide-band radio channel, modulated light beams etc.) and the direct transference of the data from the mass memory to the recording device. A radio link with relatively narrow band ensures direct transfers of data from recordings or tests between the instruments and the central recording system. …<??>Application to seismic prospecting. …<IMAGE>… |
