Design on an Autonomous Navigation and Sampling System for Multipurpose Monitoring Vessels in River Systems

Abstract

Currently, water sample collection and environmental monitoring in river basins primarily rely on manual operations. These methods suffer from issues such as low efficiency, high labor intensity, and insufficient real-time data acquisition, making it difficult to meet the complex monitoring demands of river basin environments. To address these challenges, this study designed a smart multi-purpose monitoring vessel system for river travel and sampling. The system aims to achieve autonomous navigation and automatic water sampling in diverse river basins, thereby reducing manual intervention and improving monitoring efficiency and data accuracy. The design process encompassed the development of the system's principle, workflow, motion control, and overall structural designs. Detailed calculations and analyses of key process parameters were conducted. Digital modeling methods were employed for static analysis and optimization of the mechanical structure. The results demonstrate that the designed system can effectively enhance the automation level and operational efficiency of monitoring and sampling in complex aquatic environments. It provides stable and reliable technical support for river basin water ecological monitoring, pollution prevention, water quality management, and resource management.
