SEISMIC DATA ACQUISITION |
摘要 |
A seismic system uses a plurality of remote acquisition units (12) in each of which geophone signals in digital form are temporarily stored in a buffer (24) for near-real-time transmission by a transmitter (26). The whole of the digital data is also stored in a bulk store (28) within the acquisition unit (12), from which it can be retrieved and transmitted under control of signals received by a receiver (32). This allows a central control unit to cause lost or low quality data to be retransmitted in a flexible manner. |
