摘要： A digitalization assembly of the over-sampling type includes an analog to digital converter (2) producing at a frequency F=kf small-format p samples and a digital filter (3) which, through the summation of a certain number n of over-samples, produces validated larger P-format samples at the frequency f, at instants fixed by a clock. In order to readjust the sampling instants in relation to an outside event which can occur at any time, a temporary memory store (5) is inserted between the converter (2) and the filter (3) and, according to the instant of arrival of this event, the appropriate samples to be sent towards the filter for their summation are selected.

摘要： The arrangement in the field of seismic emission-reception system changes as it progrsses along the profile explored, which modifies the respective distances between the source of seismic signals (S) and each of the siesmic receivers (Ri). In order to take account thereof, each of the acquisition boxes (Bi) used in the field for amplifying, digitizing and storing the siesmic signals received during each emission-reception cycle (or possibly a central station) is provided with a processor for determining automatically the gain to be assigned to the various amplifiers from all of the signals acquired and with selection rules taking into account the level of the signals and their evolution observed over several successive emission-reception cycles. The invention has an application in decentralized automatic control of acquisition devices.

摘要： The invention relates to a two-phase method of transmitting, to a central station (CS), seismic signals received by seismic receivers (R) and picked up by collecting units (A) disposed in the field. In the first phase, a compression is applied to each seismic trace, the ratio of which is adapted to the duration of a transmission window placed in the time intervals between successive seismic transmission-reception cycles, as well as to the rate of the transmission route used. The compressed trace as a whole is thus transmitted, allowing an operator at central station (CS) to check qualitatively that recording took place correctly in each collecting unit (A) even though he does not have the exact trace available. In the second phase, at the end of the current seismic session for example, the seismic traces are reconstituted in the central station with the necessary accuracy, either by complete transmission of the data preferably after prior compression, or, in certain cases, by transmission of residues eliminated in the first phase for the requirements of the first transmission.

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.

摘要： The invention pertains to transmission to a remote station, by means of transmission channels (generally radio transmission channels), of seismic data acquired by a data collection equipment comprising a plurality of acquisition units, each being suited to acquire, to store and preferably to compress the data to be transmitted. The invention comprises ordered storage, in a high-capacity memory (flash type memory for example) of each acquisition unit (Ai), of data obtained during successive emission-reception cycles (acquired and possibly preprocessed seismic data) so as to form a stream of stored data to be transmitted, and progressive transfer of the stored data stream from each acquisition unit to the remote station by means of the transmission channel, by reading each storage memory, with a time lag in relation to the time of their storage depending on the transmission rate of each transmission channel and on the transmission mode selected with preferably, if sending of the data of a cycle is delayed, sending of at least partial data, compressed or not, for quality control purposes. The data transmitted are reconstituted at the remote station. The method can be used for large-scale seismic data transmission.

摘要： Seismic data acquisition devices (BA) distributed in an exploration zone are divided into n groups (GA1 to GAn) and, therein, into sub-groups having each a specific frequency for communicating with a concentration unit (Ck) which is connected to a central station (1) through Hertzian channels or cables or optical fibers. Acquisition devices in the various subgroups communicate simultaneously with the corresponding concentration unit (Ck) during predetermined emission windows. The concentration unit collects the signals received from the acquisition devices to transmit them in series to station (1). The acquisition devices are adapted for delaying their own emission window according to the rank which has been previously assigned thereto within the respective subgroups thereof.

摘要： A method and an apparatus are applied to the seismic data received by receivers (Ri) distributed in the field and collected by acquisition boxes (Bi), in order to be transmitted to a central control and recording station (P), for example through hertzian channels. Digital words by adding to each N1-bit digitized signal sample, in each acquisition box, a n-bit coding suffix sufficient for detecting and correcting any transmission-related error. In order to eliminate the effect of long interferences, the method also comprises arranging the words in blocks, interleaving the words of each block at the time of the transmission, and forming digital symbols. A complementary sequence for reverse interlacing, deblocking and correcting possible errors brings the digital samples back to the original state thereof.
