In recent years, marine controlled-source electromagnetic (MCSEM) systems have become increasingly crucial for offshore resource exploration. However, the high-power operation of these systems poses significant safety challenges, mainly stemming from undetectable thermal anomalies. This study introduces a novel integration of non-contact infrared thermal imaging technology into MCSEM transmission systems, superseding conventional contact-point temperature measurement methods with comprehensive, real-time surface thermal monitoring. The proposed system effectively resolves several critical issues specific to MCSEM operations, particularly electromagnetic interference (EMI) resilience, high-temperature operational stability, and data transmission bandwidth limitations. Our hardware–software co-design methodology achieves dual optimization of measurement efficiency and operational safety. Hardware advancements incorporate Gigabit Ethernet for enhanced data throughput, EMI-resistant circuitry for improved signal integrity, and motorized zoom lenses for adaptive infrared imaging capabilities. Concurrently, our software architecture facilitates real-time thermal visualization, robust offline data storage, and intelligent region-of-interest temperature alert mechanisms. This research establishes a new operational paradigm for MCSEM monitoring systems, significantly enhancing safety protocols and enabling proactive risk management in high-power offshore applications.
