Application of Non-Contact Infrared Monitoring Technology in Marine Controlled-source Electromagnetic Transmission System

Abstract. In recent years, marine controlled-source electromagnetic (MCSEM) systems have emerged as a crucial technology in offshore resource exploration. Nevertheless, the high-power operations inherent to these systems present substantial safety challenges, primarily due to undetectable thermal anomalies. This study introduces a novel integration of non-contact infrared thermal imaging technology into MCSEM transmission systems, superseding conventional point-contact 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 constraints. Through a sophisticated hardware-software co-design approach, we have optimized both 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.
