Abstract
The system includes a plurality of acquisition devices (A.sub.i) for collecting signals received by receivers (Rk) and a central control, recording and processing station. This station manages the performance of the devices (A.sub.i), of successive signal acquisition cycles and thereafter the centralization thereof. In order to relieve the central station of part of the tasks thereof in case of a high volume of data to be collected and processed, acquisition devices are used which have management processors (2, M.sub.1, M.sub.2) and with complementary computing processors (7, M.sub.3) programmed for carrying out processings of the data before the transmission thereof. Various combinations of seismic signals, data compression, and quality controls are performed in real time during the phase of setting of the seismic equipment (seismic receivers and acquisition device electronics (CA1 to CAn) in the devices A.sub.i in the field), etc, immediately accessible to operators in the field.
