The intelligent anti-collision warning system for workboats is an innovative technological solution developed to enhance the safety and reliability of vessels in complex operational environments. The system focuses on three key functions: short-range obstacle detection, crew behavior monitoring, and hazard element identification on board, providing comprehensive safety coverage. In terms of technology, it employs millimeter-wave radar for distance measurement and obstacle avoidance, image detection and processing techniques, and a risk assessment and warning mechanism. These technologies ensure the system's efficiency and practicality in real-world applications. By effectively reducing collision risks and protecting crew safety, this system offers robust support for smooth vessel operations.
