Design of Control Platform for the Marine Electromagnetic Transmitting System Based on PLC System and LabVIEW

摘要

The marine controlled source electromagnetic transmitting method could greatly improve the success rate of the offshore drilling and reduce drilling risk greatly. So it has been widely used in the abroad exploration industry of marine oil and gas in recent years. As a primary means of subsea communications, power line communication (PLC) system plays a major role in the marine electromagnetic exploration system. The communications platform of marine controlled source electromagnetic transmission system has been built by PLC system and the LabVIEW software in this paper. The GPS module has been used for time synchronization in this platform. The communication between the deck control platform and subsea uses the PLC system. And marine transmitter control platform could timely display and save the information of the operating, operating current and operating frequency in the subsea system. The experiment results verify that this platform could work stably for a long time and have the high transmission rate about 1kb/s.
