Data Transmission and Anomaly Analysis of Ocean Exploration Source System

The digital source control system used in marine seismic exploration has the advantages of long transmission distance, strong anti-interference ability and large data volume. However, problems such as GFSM (integrated sensor unit) faults and near-field data affected by inductive noise always come with the using process. Aiming at this situation, this paper combined problems such as bus composition, digital system TDM transmission mode, data parity check mode, inter-line interference and series induction, analyzed the parity check mode of GFSM data through Python program. Then improved the accuracy of system fault judgment. By analyzing the coupling induction of capacitance, inductance and resistance, it is concluded that inductance has little influence on data accuracy. In conclusion, methods above are capable of resolving the problems caused by GFSM faults and reducing the impacts on construction efficiency and product quality.
