Research on On-line Data Transmission Technology in Marine Controlled Source Electromagnetic Transmitter

This paper proposes a method for acquiring complete data from the Marine Controlled Source Electromagnetic (MCSEM) transmitter during offshore experiments. The lower computer's modules are designed with STM32 MCU and μC/OS-II real-time operating system, while the upper computer's software is designed using Python language to match the lower computer. This allows workers on the deck to control the lower computer in real-time for high-precision data acquisition, storage, Ethernet file transfer, and other tasks. The joint tests between the lower and upper computers have demonstrated the stability and reliability of the online transmitter system, which provides significant convenience for offshore exploration.
