FIELD: seismic prospecting. ^ SUBSTANCE: invention can be used for conducting 2D, 3D, 4D seismic prospecting by means of multichannel telemetering seismic stations. Multichannel telemetering system for collecting seismic data has central seismic data control and registration device which has in turn excitation synchronizing system and control computer. Control and registration central control unit is connected with field control units due to trunk line communication channels. Field control units are connected with field registration devices through linear communication channels. Field registration devices are connected with group of geophones. Seismic data central control and registration unit has also trunk line controller which has the first input-output connected with input-output of control computer. The second and the third input-outputs are connected correspondingly with first and second trunk line channels and fourth input-output is connected with input-output of excitation synchronization system through wire. ^ EFFECT: improved efficiency and reliability of measurements. ^ 4 cl, 4 dwg |
